CLIFFORD HUDIS: Welcome to this ASCO in Action podcast brought to you by the ASCO Podcast Network, a collection of nine programs covering a range of educational and scientific content and offering enriching insights into the world of cancer care. You can find all of the shows, including this one, at podcast.asco.org.

The ASCO in Action podcast is a series where we explore the policy and practice issues that impact oncologists, the entire cancer care delivery team, and the individuals we care for-- people with cancer. My name is Dr. Clifford Hudis. And I'm the CEO of ASCO and the host of the ASCO in Action podcast series.

For today's podcast, I am especially pleased to have as my guest my friend, colleague, and mentor Dr. Richard Schilsky, ASCO's chief medical officer. Now, I am sure that many of our listeners have already heard that Dr. Schilsky will be leaving ASCO in February of 2021, retiring.

However, I want to reassure everybody that even in retirement, he will continue to make contributions and provide leadership to all of us. And his illustrious and path-blazing career in oncology spanning more than four decades is not quite over thankfully.

Rich is ASCO's first chief medical officer. And as such, he has made a truly indelible mark on all of us. He started with a proverbial blank piece of paper. The position had no precedent. It had no budget. It had no staff.

But now after just eight years in the role, he has helped make the CMO a critically important position at the society. And I have to say that success is more than anything due to Rich's vision and his leadership. And that's some of what we'll be talking about today.

So Rich, thank you very much for joining me today for what I hope is going to be a great casual but informative conversation about your amazing career, your unique role at ASCO, and maybe most importantly in the end what you see for the future of oncology not just in the United States, but around the world. Thanks for coming on, Rich.

RICHARD SCHILSKY: Thanks, Cliff. It's great to be here today.

CLIFFORD HUDIS: So with that, let's just dive right in and start at the very beginning. Rich, tell everybody why you decided to become an oncologist and maybe share a little bit about what those early days looked like for you and, in that context, what it was like to have cancer at the beginning of your career.

RICHARD SCHILSKY: Well, I knew from an early age that I wanted to be a doctor. And in fact, I had written a little essay when I was in sixth grade as a homework assignment called My Ambition. And my mother had tucked that away in a scrapbook. And I found it a number of years ago. And on rereading it, it was quite amazing to me to see what I was thinking about even then.

Because I said not only did I want to be a doctor, but I didn't think that was enough, that I wanted to be a medical researcher because I wanted to discover new information that would help people heal from whatever their diseases might be.

And so it was never really any doubt in my mind that I would be a physician. I went to medical school at the University of Chicago. But I was living in New York City at the time having grown up in Manhattan. And the only year we had off in medical school, the only time we had off in medical school, was the summer between the end of the first year and the beginning of the second year.

So during that time, I went back to Manhattan. And I was able to get a fellowship from the American College of Radiology that allowed me to essentially hang out in the radiation therapy department at New York University Medical Center, which was within walking distance of where I grew up. And so I would go over there every day. And I was taken under the wing of a young radiation oncologist.

And of course, I wasn't really qualified to do anything at that point except to follow him around, talk and listen to the patients. But that turned out to be a really formative experience for me because we saw the whole gamut of cancer. We saw head and neck cancers. We saw lung cancer. We saw patients with breast cancer and prostate cancer.

And in those years-- this is the early 1970s-- many of these patients have fairly locally far advanced disease and were quite debilitated by it. But listening to their stories, hearing about their hopes and their struggles, really demonstrated to me the human side of cancer.

So I went back to school and thought about this in the context of my own personal experience, which dated back to when I was in college when my mother's mother, my maternal grandmother, was diagnosed with breast cancer. This was 1968. And as you well know, there were very few therapies available for breast cancer in the late 1960s, mostly hormone therapies.

And my grandmother had the treatment that was considered standard of care at that time, which was extended radical mastectomy followed by chest wall radiation. And some years after that first mastectomy, she had a breast cancer that developed in the opposite breast and had a second extended radical mastectomy and chest wall radiation. And these were very traumatic and disfiguring procedures for her to go through.

Anyway, long story short is after another few years, she developed bone metastases and then brain metastases. And there was really very little that could be done for her other than hormone therapies. And having observed her go through that illness and realizing how limited our treatment options were and then having the experience after my first year in medical school pretty well cemented for me that I wanted to be an oncologist.

I thought actually about being a radiation oncologist. But then I did my internal medicine rotation in medical school, fell in love with internal medicine. And that sort of put me on the path to be a medical oncologist.

The clinical challenge of caring for cancer patients, the emotional attachment to those patients, and, of course, even then, the unfolding biology of cancer was so intellectually captivating that I actually applied for oncology fellowship when I was a senior medical student. So even before going off to do my medical residency, I had already been accepted as a clinical associate at the National Cancer Institute to start two years hence. And that's how I became an oncologist.

CLIFFORD HUDIS: So it's so interesting. Because, of course, the story I'm sure for many people interested not just in oncology, but even medical education, there are little things that don't happen nowadays that happened with you like that last little vignette about the early acceptance into an advanced training program before your fellowship among other things.

Can you remind us about the timeline? Because I think one of the things that many of our listeners often can lose sight of is just how new oncology really is as a specialty. ASCO itself founded in 1964. And the first medical oncology boards were mid-'70s, right? So you were in med school just before that second landmark, right?

RICHARD SCHILSKY: That's right. I graduated from medical school in 1975. I started my oncology fellowship in 1977. And I got board-certified in medical oncology and joined ASCO in 1980. And so that was the time frame at that point.

CLIFFORD HUDIS: So the internal medicine was actually, if I heard you right, just two years, not the now traditional four.

RICHARD SCHILSKY: Yeah. I was a short tracker. I did only two years of internal medicine training rather than three. I did my training at Parkland Hospital and University of Texas Southwestern in Dallas with at that time a legendary chair of medicine, Don Seldin, who I had to get permission from him to leave the program prior to completing the third year of residency because I had already been accepted into fellowship at NCI.

And he, Seldin, who was a brilliant chairman and a brilliant nephrologist, was not at all interested in cancer. And it took a bit of-- I was going to say arm twisting, but it really took bleeding on my part to get him to agree to allow me to leave the residency program to go to the NCI. But he eventually agreed.

And in those years, the first-year clinical fellowship at the NCI was like being an intern all over again. There were about 15 of us. We were on call overnight in the clinical center once every two weeks. We cared for all of our inpatients as well as had a cadre of outpatients.

We did all of our own procedures. We had no intensive care unit. So patients who were sick enough to require ventilator support, we cared on the floor in the inpatient service on our own with guidance from senior oncologists. It was a bit different from the way it is now. But, of course, it was fantastic on-the-job training because we just learned a ton and had to learn it very quickly.

CLIFFORD HUDIS: So that's actually a great segue to the advances because there was a lot to learn then. But, wow, there's a lot more to learn, I think, now. And I have real sympathy for trainees and younger oncologists for the breadth of what they need to learn. Again, just testing your memory, but platinum came along pretty much in the mid-'70s as well, right? That was a pivotal expansion of the armamentarium for us.

So what do you see-- when you summarize progress in cancer research and care over these decades, what do you think are the most pivotal or revolutionary milestones that you identify over the span of your career?

RICHARD SCHILSKY: Yeah. It's really interesting to think about it historically. There were the early years of discovery in oncology from the 1950s to the 1970s when we really had the introduction of the first chemotherapy drugs and the miraculous observation that people with advanced cancer could actually obtain a remission and, in some cases, a complete remission with chemotherapy and combination chemotherapy in particular.

And so that was the formative years of oncology as a medical specialty and really proof of concept that cancer could be controlled with drugs. When we got into the 1980s, the 1980s in many respects were the doldrums of progress in clinical oncology. There really was not a lot of innovation in the clinic.

But what was happening and what was invisible to many of us, of course, was that was the decade of discovery of the fundamental biology of cancer. That's when oncogenes were discovered, when tumor suppressor genes were discovered, when it became clear that cancer was really a genetic disease. And that is what transformed the field and put us on the path to targeted therapy and precision medicine as we think of it today.

So I think that clearly understanding the biology of cancer as we do now and all that it took to lead us to that point, which was a combination of understanding biology, developing appropriate technology that would, for example, enable the sequencing of the human genome and then the cancer genome.

And the other formative technology in my opinion that really changed the way we care for cancer patients was the introduction of CT scanning. When I was still a fellow at the NCI, we did not have a CT scanner. If we needed to get detailed imaging of a patient, we did tomography. And if you remember what tomograms looked like, they were really blurry images that you could get some depth perception about what was going on in the patient's chest or abdomen. But they really weren't very precise.

When CT scanning came along, it really revolutionized our ability to evaluate patients, assess the extent of disease, stage them in a much more precise way, which then allowed for better patient selection for curative surgery, better radiation therapy planning. So we don't often point to imaging advances as some of the transformative things that paved the way in oncology, but I think imaging is really overlooked to some extent.

So I think the technology advances, the biological advances, are the things that really allowed the field to move forward very quickly. And by the time we got into the mid-1990s, we were beginning to see the introduction of the targeted therapies that have now become commonplace today.

And then it was around 2000, I think, that we saw the introduction of Gleevec. And I'm reminded always about an editorial written by Dan Longo in The New England Journal a few years ago. And Dan and I were fellows together. We worked side by side on the wards at the clinical center and became very good friends.

And Dan in his role as a deputy editor of The New England Journal wrote an editorial a few years ago that was titled "Gleevec Changed Everything." And Gleevec did change everything. It changed our entire perception of what were the drivers of cancer and how we might be able to control cancer very effectively and potentially put it into long-term remission.

Now, of course, we know now that the whole Gleevec story is more of an exception than a rule in targeted therapy. And, of course, we know that tumors become resistant to targeted therapies. But we couldn't have known any of this back in the early years of oncology because we had no real insight into what caused cancer to grow or progress. And the notion of drug resistance, while we realized that it occurred, we had no idea what the mechanisms were. So it's such a different landscape now than what it used to be. It's quite remarkable.

CLIFFORD HUDIS: So as you tell the story, there's, of course, a lot of focus on technology, whether it's biology and understanding the key features of malignancy or imaging or more. But what I also note in your story and I want to come back to is the people. And I can't help but reflect on where we are in this moment of the COVID-19 pandemic. Yes, we've moved to telemedicine. Everything can be accomplished via technology. And, yet, the human touch is so important.

When we think about being in the room with people, when we think about face to face from the context of career development and your own career, you touched on Dr. Seldin, I think, already from the perspective of internal medicine training. But are there are other mentors or important shapers of your career that you think we should know about?

RICHARD SCHILSKY: Well, probably, the most influential person early in my career in medical school was John Altman. John, you may know, was the inaugural director of the University of Chicago's NCI-designated Cancer Center, which was one of the very first NCI-designated cancer centers in 1973 after the National Cancer Act of 1971 created the cancer centers program.

And John, who was a leading oncologist studying Hodgkin and non-Hodgkin's lymphoma, was a faculty member there. He was the director of our cancer center as I said. He took me under his wing even when I was in medical school and served as a real role model and mentor to me.

When I was in my internal medicine training as I mentioned earlier, Don Seldin, the chair of medicine, was never particularly interested in oncology. So, to some extent, I didn't have-- I had great internal medicine training. But I did not have good mentorship in oncology. When I got to the NCI, then my whole world really opened up.

And the two pivotal people there in my career were Bob Young, who was chief of the medicine branch and was my clinical mentor and remains a mentor and friend to this day, and then, of course, Bruce Chabner, who was the chief of the clinical pharmacology branch.

And in my second year of fellowship when we all went into the laboratory, I went into Bruce's lab. And that's where I really got interested in the mechanism of action of anti-cancer drugs and ultimately in drug development and early phase clinical trials. And both Bob and Bruce remain very close to me even today.

CLIFFORD HUDIS: So I'm concerned about time on our call today on our discussion. Because we could obviously fill lots of hours on all of these remarkable experiences and amazing people you worked with. But I'm going to ask that we fast forward a little bit.

You and I share, I think, passion and love for ASCO. So I think that it's reasonable for us to focus a little bit on that for the time we have left here. You didn't start out obviously as chief medical officer at ASCO. But you were a really active ASCO volunteer and leader. Maybe tell us a little bit about some of the ASCO volunteer roles that you engaged in and what that meant to you at the time and how that led to this role.

RICHARD SCHILSKY: Well, I'll be brief. I joined ASCO in 1980 at the first moment that I was eligible to join ASCO. I had attended my first ASCO meeting the year before, 1979, when I was still in my fellowship training. And it was clear to me even then when the whole annual meeting was about 2,500 people in two ballrooms in a hotel in New Orleans that that was a community of scholars and physicians that I wanted to be a part of.

And so, over the years, I did what people do even today. I volunteered to participate in whatever ASCO activity I could get involved with. Over the years-- I think I counted it up not too long ago-- I think I served or chaired 10 different ASCO committees, more often serving as a member, but in a number of those committees also serving as the chair over many years.

And as I became more deeply involved in ASCO and saw other opportunities to engage, I had the opportunity to run for election to the board and was-- after a couple of tries was elected to serve on the board and then eventually elected to serve as ASCO president in 2008-2009.

But the attraction of ASCO in many ways was a community of diverse but, in many ways, like-minded people, people who had similar passion and drive and focus. But I think what you get at ASCO in many ways is the wonderful diversity of our field. If you work in a single institution for much of your career as I did and as you did, you get to know that institution pretty well. You get to know its perspectives and its biases and its strengths and its weaknesses.

But there's a whole world of oncology out there. And you can get exposed to that at ASCO because you meet and work with colleagues from every clinical setting, every research setting, people who have remarkable skills and interests and passions. And it's just a wonderful environment to help develop your career. So I consider myself to be extremely fortunate to have had the journey in ASCO that I've had culminating, of course, with ultimately my coming on the staff as ASCO's first chief medical officer.

CLIFFORD HUDIS: We often joke about that blank sheet of paper. But in retrospect, it's very obvious that you had built up that collection of LEGO blocks, and then you assembled them all into the ASCO Research Enterprise, a name you gave it.

And it really, in retrospect, builds, I think, very cleanly upon all of your prior experience, but also the vision that you developed based on that experience for how research should be conducted. Can you maybe share with everybody the scope and vision for the ASCO Research Enterprise, what the intent was, and where you see it going, and what it includes today?

RICHARD SCHILSKY: Sure. I won't claim that I came to ASCO with the whole thing fully developed in my mind. As you said, when I came, I literally did have a blank slate. Allen Lichter, who hired me, said, come on board and help me make ASCO better. And so I, in a sense, reverted to what I knew best how to do, which was clinical research.

And having in my career been a cancer center director, a hem-onc division chief, a cooperative group chair, I had a lot of experience to draw on. And it was obvious to me that ASCO was fundamentally an organization that took in information from various sources, evaluated it, vetted it, collated it, and then disseminated it through our various channels, most notably our meetings and our journals.

But ASCO itself did not contribute to the research enterprise. And that seemed to me to be a lost opportunity. We knew that ASCO had lots of data assets that could be of interest to our members and to the broader cancer community. But they were scattered all around the organization and not particularly well annotated or organized. So we began to collate those. And they are now available to ASCO members on the ASCO data library.

I recognized that we did not have an organized unit in ASCO to support or facilitate or conduct research. So, in 2017, we formed the Center for Research and Analytics and brought together staff who were already working at ASCO but scattered in different departments but all people who had an interest in clinical research or research policy and brought them into this new unit, which has really become the focal point for research work at ASCO.

We recognized that ASCO members for many years were interested in surveying their colleagues, surveying other ASCO members, to help advance research questions. But ASCO actually had a policy that prohibited that.

So that never really made good sense to me. It seemed like a lost opportunity. And we were able to create a program and have the ASCO board approve it whereby any ASCO member could opt in to participate in what we now call the Research Survey Pool.

And in doing so, they are essentially agreeing to participate in research surveys conducted by their colleagues. So that program is now up and running. There are, I think, eight surveys that have been completed or are currently in the field. And this is now a service that ASCO provides through CENTRA to its members to enable them to survey their colleagues for research purposes.

Most importantly, I think we saw an opportunity back in 2014 or 2015 to begin to learn from what our colleagues were doing in clinical practice as they began to deploy precision medicine. And there was a lot of genomic profiling that was going on at that time. It was revealing actionable alterations in roughly 30% or so of the tumors that were profiled.

But there was a lot of difficulty in doctors and patients obtaining the drugs that were thought to be appropriate to treat the cancer at that particular time because most of those drugs would have to be prescribed off label. And there was not a sufficient evidence base to get them reimbursed. And, moreover, even if they could be reimbursed, there was no organized way to collect the patient outcomes and learn from their experiences.

So that led to us developing ASCO's first prospective clinical trial, TAPUR, which really solves both of those problems. Through the participation of the eight pharmaceutical companies that are engaged with us in the study, we are providing-- at one point, it was up to 19 different treatments free of charge to patients.

These are all marketed drugs but used outside of their FDA-approved indications. And we were collecting data on the patients, the genomic profile of cancer, the treatment they received, and their outcomes in a highly organized way.

And so now this is a study that we launched in 2016. We're now almost to 2021. We have more than 3,000 patients who have been registered on the study, meaning consented to participate, more than 2,000 who have been treated on the study. And we are churning out results as quickly as we can about which drugs are used or not useful in the off-label setting for patients whose tumors have a specific genomic profile.

So we built all this infrastructure. And having this in place has also then allowed us to respond rapidly to unmet needs. So when the COVID-19 pandemic overwhelmed all of us, and when our members were looking for information about what was the impact of COVID-19 on their patients, one of the things we were able to do because we had CENTRA, because we had a skilled staff and an infrastructure, was to very quickly stand up the ASCO COVID-19 registry, which we launched in April of this year.

And there are now about 1,000 patients who've enrolled in the registry from around 60 practices that are participating. And we will follow these patients now longitudinally and learn from their experiences what has been the impact of the COVID-19 illness on them and their outcomes, how has it disrupted their cancer care, and ultimately how that impacts their overall cancer treatment outcomes.

So as I now contemplate leaving ASCO after eight years having started with a blank slate, I'm very proud of the fact that I think I'm leaving us with a remarkable infrastructure. We now have a clinical trials network of 124 sites around the country participating in TAPUR that we never had before. We have through the work of CancerLinQ a real-world evidence data generator that is beginning to churn out valuable insights.

We have a capacity to survey ASCO members for research purposes. We have an ability to stand up prospective observational registries to gather information longitudinally about patients and their outcomes. We have a core facility in CENTRA with highly skilled data analysts and statisticians that can support these various research activities.

So ASCO is now primed, I think, to really contribute in a very meaningful way to the gaps in knowledge that will forever exist in oncology just because of the complexity of all the diseases we call cancer. And that's what I mean by the ASCO Research Enterprise. It is in fact remarkable and, I think, powerful enterprise if we continue to use it effectively.

CLIFFORD HUDIS: Well, that's an interesting segue to my next thought, which is really about what comes next. I'll talk about you. But let's start with ASCO first. Your successor, Dr. Julie Gralow, obviously has been announced publicly. She's an accomplished clinician and researcher. She has a known recognized passion for patients, patient advocacy, clinical research through her leadership at SWOG but also health care equity and global oncology.

So from your perspective, having created all of these assets and resources, what advice would you give Dr. Gralow publicly on how to make the position hers, what to take us to next? And I do want to acknowledge for everybody listening that the hints I've been making up until now are that Rich has agreed that he will continue to contribute as a leader to TAPUR for the short term, at least, at least the next year helping Julie get fully oriented to this program and others. So what will your advice be to Julie?

RICHARD SCHILSKY: That's a great question. She's a great selection. And congratulations on hiring her. I think there are two key issues, I think, maybe three. One is to have a broad scope and cast a wide net. Oncology care and cancer research and cancer biology are incredibly complicated and nuanced and broad in scope.

And although Julie is an accomplished breast cancer clinician and researcher, in this role at ASCO, you have to be very broad. You have to understand all of cancer care, all of cancer research, all of policy and advocacy not as an expert in necessarily in any one aspect of ASCO's work, but you have to understand the impact of all of those things on cancer care providers and on cancer patients.

And it's important to always be looking to the future. The future is going to be here before you know it. And we as a professional society have to prepare our members for that future. So that leads me to the second point, which is listen to the members.

The members are the people on the front lines who are delivering care to patients every day. And, fundamentally, ASCO's job is to be sure that our members have all the tools and knowledge and resources that they need to deliver the highest quality care to patients every day. So listening to what they need, what their struggles are, what their burdens are, is extremely important.

And then the third thing I would recommend to her is that she get to know the staff and colleagues that she'll be working with. ASCO has a remarkably accomplished, skilled, motivated, passionate staff, many of whom have been with the organization for years, if not decades, who understand what ASCO can and cannot do and who understand what our members need. And she will be well advised to spend a good portion of her first few months on the job just listening and learning from her colleagues.

CLIFFORD HUDIS: That's always good advice for anybody making a big career move. But, of course, the wisdom you bring to it is palpable and much appreciated. And I'm sure Julie will be taking your advice. And, by the way, so will I continue to do that even after you make your move. So speaking of your retirement, can you share with us a little bit about what it's actually going to look like for you? Is it about family? Or are you still going to have some professional engagement? Again, I suggest that there might be some already, but maybe you could expand on it.

RICHARD SCHILSKY: Yeah. I'm still fully focused on my work at ASCO. And, of course, as you know, when I wake up on February 15, I will no longer be ASCO's chief medical officer. And it's going to be a bit of a rude awakening. Fortunately, I will be able to continue my engagement with ASCO through the TAPUR study as you mentioned. I will, of course, forever be at ASCO member and a donor to Conquer Cancer and be willing to serve the society in any way.

I have a number of activities that I've been involved with even throughout my time at ASCO. Not-for-profit boards, for example-- I'm on the board of directors of Friends of Cancer Research. I'm on the board of directors for the Reagan-Udall Foundation for FDA.

I plan to continue with those activities as long as they'll have me. I've been serving the last few years on the board also of the EORTC, the large European cooperative clinical research group. And I expect to continue in that role.

Beyond that, I will see what opportunities come my way. I think one of the things about retirement if you will that I'm looking forward to is the opportunity to pick and choose what to work on based on what interests me without having the burdens of having a full-time job.

On the personal front, of course, we're all looking forward to crawling out from the pandemic. I've basically been locked in my home outside Chicago since March. And I'm looking forward to getting back out to a little bit of a social life. As you know, I have two grown daughters and now three grandchildren, two of whom are in Atlanta, one of whom is near by us in the Chicago area. So looking forward to spending time with them as well.

So it will be a change for me to be sure after working as hard as-- I feel like I've worked for really now 45 years since I graduated from medical school. But I also feel like I'm not quite done yet and that I still have ways in which I can contribute. I just feel like at this point, maybe it's time for me to choose how I want to make those contributions and spend a little bit more time doing some other things.

CLIFFORD HUDIS: Well, both you and my predecessor, Allen Lichter, are modeling something, have modeled something, that I think is not often discussed but can be very important. For people and for institutions, change is not a bad thing. And setting the expectation that you will pour your heart and soul into something but not necessarily do it alone or forever and not prevent others from taking that role at some point, that's a really-- I think it's a selfless kind of sacrifice in a way.

Because, of course, you could stay and do what you're doing for longer. But as you and I have discussed, there is a value for all of us collectively in having fresh eyes and new people take organizations in a new direction. That's how I ended up here frankly. And I think that's the kind of opportunity you're creating right now, something that should be celebrated in my opinion.

RICHARD SCHILSKY: Well, thanks. And I couldn't agree more. When I look back at the arc of my career and having all the different kinds of leadership roles that I've had, I basically have made a job change every 8 to 10 years. I was the director of our cancer center for nearly 10 years. I was associate dean for clinical research at the University of Chicago for eight years, another position that I created from a blank slate at that institution.

The exception was serving 15 years as a CALGB group chair. But that was a position I really loved and enjoyed and felt like at the end of the first 10 I hadn't quite accomplished everything I wanted to accomplish.

But the point is that I think it is both necessary for organizations to have regular leadership change. And it's also refreshing for us as individuals. There gets to a point where you feel like you can do your job in your sleep. And I actually think that's a good time to make a change.

Because if that's the way you feel, you're not being sufficiently challenged. And you're probably not being sufficiently creative. And so it's a good time to move on and refresh your own activities and give your organization a chance to bring in someone to hopefully build on whatever you've created and bring it to the next level.

CLIFFORD HUDIS: Well, I agree with all that, although I think your comment there about doing the job in your sleep would not apply because I'm pretty confident that the environment and opportunities have continued to evolve in a way that has made it interesting from beginning to end. But you don't have to rebut me on that. I just want to thank you very, very much, Rich.

As we set up this podcast, I expected that we would have a really fun and enlightening conversation. And, of course, you did not disappoint. We could talk for much, much longer if we only had the time.

On a personal note to you and for the benefit of our listeners, I want to share that Rich has been for me a remarkable friend and mentor and colleague. I first met Rich at the very beginning of my career when my mentor, Larry Norton, pushed me out from Memorial into the larger world. And he did that first and primarily through ASCO and the Cancer and Leukemia Group. Those are really the two places where I was exposed to the world.

And through the CALGB, Rich really began to offer me and others, many others, opportunities that shaped careers plural, mine and others. So when I got to ASCO as CEO, Rich was there. And I knew I could always depend on you to be clearheaded, intellectually precise, constructive, visionary. And the thing about you, Rich, is that you never would say yes to anything unless you knew for sure you could do it and indeed, I think, how you could do it.

I always share this story which your staff at CENTRA pointed out to me. And I have to admit that I hadn't picked it up myself. But in all the years of now working down the hall from Rich, probably hundreds and hundreds of hours of meetings, he never has taken a note in front of me. And, yet, everything we talk about, every action item we conclude to pursue, they all get done.

So I don't know, Rich. You have a remarkable way of organizing your thoughts and your plans, keeping it together, and getting things done. And I'm going to miss that tremendously in the years ahead.

So, Rich, I want to say congratulations. Congratulations on reaching this really important milestone in your life. Thank you on behalf of ASCO and the broader oncology community and the patients we care for and their families for making the world a better place. And just as a small thing, thank you for joining me today for this ASCO in Action podcast.

The ASCO in Action Podcast is ASCO's podcast series that explores the policy and practice issues that impact oncologists, the entire cancer care delivery team, and the individuals we care for—people with cancer.

I'm Dr. Clifford Hudis, CEO of ASCO and the host of the ASCO in Action podcast series. For this podcast, I wanted to share with listeners a preview of the 2020 ASCO Advocacy Summit and Week of Action taking place September 14-18.

Typically, ASCO gathers volunteer advocates in Washington, D.C., in September for education sessions and in-person meetings with their Members of Congress.

Due to the COVID-19 pandemic—like so many events scheduled to take place this year—the 2020 ASCO Advocacy Summit will be a virtual event, but that said, participants can expect the same advocacy and education opportunities that the event provides every year.

ASCO volunteers will meet with Members of Congress and their staff by phone or video to advocate for policies that will improve access to high-quality, equitable care for people with cancer and ensure robust funding for cancer research.

Advocacy Summit attendees will also attend webinars to receive education and training on lobbying Congress and the current political landscape.

What is different this year is our online Week of Action, which will give all ASCO members an opportunity to advocate on critical issues of great importance to the cancer care delivery system in the United States.

Participants in the Week of Action will amplify the Advocacy Summit's messages through email and social media messages to Members of Congress using ASCO's ACT Network. And, it's easy to get involved and make your voice heard. You just need to click on the link to the ACT Network in the Advocacy Center on ASCO.org and sign up to receive ASCO ACT Network emails. Then, you'll get all the information on the fastest and easiest ways to contact lawmakers delivered directly to your inbox. We hope you will participate as much as you can—the effort will take just minutes. Even one message a day by every ASCO member to your representatives in Congress will have a tremendous impact.

During the virtual Advocacy Summit, which will be held in the middle of the Week of Action on September 16, ASCO volunteer advocates will have their virtual meetings with Members of Congress and their staff. The three issues or "legislative asks" that they will be discussing will be the same asks that ASCO members will contact their Members of Congress about during the Week of Action.

One, we will ask Congress to support legislation—The CLINICAL TREATMENT Act, which will give all Medicaid beneficiaries coverage of routine costs when enrolled in clinical trials—coverage Medicare and private insurance plans already provide. The importance of improving health equity has become even more apparent during the COVID-19 pandemic, and this legislation takes us one step closer to that goal.

Two, ASCO volunteer advocates will request lawmakers to co-sponsor the Safe Step Act, which will help protect patients from harmful step therapy protocols, which ASCO believes is never appropriate in the treatment of cancer.

And three, we'll address the impact COVID-19 has had on cancer practices and research. Specifically, advocates will ask Congress to endorse maintaining reimbursement flexibilities for telehealth, as many oncology practices have rapidly transitioned to telehealth to ensure patients continued receiving treatment during the pandemic.  We'll also be asking Congress to provide emergency funding to the National Institutes of Health to mitigate disruptions caused to labs and clinical trials by COVID-19, and to restart research across the county.

These are the same issues that participants in the Week of Action will be advocating for all week long in their outreach to Congress.

The goals of the Advocacy Summit and Week of Action are to advance priority legislation, amplify the collective voice of the cancer care community on Capitol Hill, and to get ASCO members involved in advocacy initiatives.

Members of Congress and their staff have grown accustomed to virtual constituent meetings, and personal stories continue to be the most effective form of advocacy, so the Advocacy Summit and Week of Action—even virtually—remain critical to ASCO's larger advocacy efforts.

In addition to the meetings and messages between advocates and lawmakers, the ASCO Advocate of the Year and the Congressional Champion for Cancer Care will be named during the Advocacy Summit.

In closing today, I encourage everyone listening today to follow the Advocacy Summit through social media by way of the hashtag ASCO Advocacy Summit (#ASCOAdvocacySummit) on Twitter AND to participate in the Week of Action through the ACT Network.

ASCO President Lori J. Pierce, MD, FASTRO, FASCO, joins ASCO CEO Dr. Clifford A. Hudis in the latest ASCO in Action podcast to discuss how her childhood inspired her to become an oncologist and how the theme of her presidential year, "Equity: Every Patient. Every Day. Everywhere." is more important than ever as the country responds to a healthcare pandemic that is disproportionately impacting people of color.

"Every patient, no matter who they are, deserves high-quality care and every patient has the right to equitable care," says Dr. Pierce. "We have to get to the root causes to understand the barriers that patients face if we're going to really make a difference, so it's important to me that equity be front and center of everything that we do."

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I'm interviewing Dr. Sonam Puri from Moffitt Cancer Center, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer with Driver Alterations: ASCO Living Guideline, Version 2026.3.0." It's great to have you here today, Dr. Puri.

Dr. Sonam Puri: Thanks, Brittany.

Brittany Harvey: And then just before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Puri, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

So then, to dive into the content that we're here today to talk about, Dr. Puri, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer with driver alterations is updated on an ongoing basis. So, what data prompted this latest update to the recommendations?

Dr. Sonam Puri: So Brittany, non-small cell lung cancer is one of the fastest-moving areas in oncology right now, particularly when it comes to targeted therapy for driver alterations. New data are emerging continuously from clinical trials, regulatory approvals, real-world experience, which is exactly why these are living guidelines. The goal is to rapidly integrate important advances as they happen, rather than waiting for years for a traditional update.

Since the last full update of the ASCO Stage IV Non-small Cell Lung Cancer Guideline with Driver Alterations published in 2024, there have been seven new regulatory approvals and changes in first-line therapy for some driver alterations. [This version] of the "Stage IV Non-small Cell Lung Cancer Guidelines with Driver Alterations" represents a full update, which means that the panel reviewed and refreshed every applicable section of the guideline to reflect the most current evidence across therapies including sequencing and clinical decision-making. This is to ensure that clinicians have up-to-date practical guidelines that keep pace with how quickly the field is evolving.

Brittany Harvey: Absolutely. As you mentioned, this is a very fast-moving space and this full update helps condense all of those versions that the panel reviewed before into one document, along with additional approvals and new trials that you reviewed during this time period.

So then, the first aspect of the guideline is there's a new overarching recommendation on biomarker testing. Could you speak a little bit to that updated recommendation?

Dr. Sonam Puri: Yeah, definitely. So the panel has discussed and provided recommendations on comprehensive biomarker testing and its importance in all patients diagnosed with non-small cell lung cancer. Ideally, biomarker testing should include a broad-based next-generation sequencing panel, rather than single-gene tests, along with immunohistochemistry for important markers such as PD-L1, HER2, and MET.

These results really drive treatment decisions, both in frontline settings for all patients diagnosed with non-small cell lung cancer and in subsequent line settings for patients with non-small cell lung cancer harboring certain targetable alterations. Specifically in the frontline setting, it helps determine whether a patient should receive upfront targeted therapy or immunotherapy-based approach. We now have strong data that shows that complete molecular profiling results before starting first-line therapy is associated with better overall survival and actually more cost-effective care.

Using both tissue and blood-based testing can improve likelihood of getting actionable results in a timely way, and we've also provided guidance on platforms that include RNA sequencing, which are specifically helpful for identifying gene fusions that might be otherwise missed with other platforms. On the flip side, outside of a truly resource-limited setting, single-gene PCR testing really should not be routine anymore. This is what the panel recommends. It's less sensitive and inefficient and increases the risk of missing important actionable alterations.

Brittany Harvey: Understood. I appreciate you reviewing that recommendation. It really helps identify critical individual factors to match the best treatment option to each individual patient.

So then, following that recommendation, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer with a driver alteration?

Dr. Sonam Puri: Since the last full update in 2024, there have been four additional interim updates which were published across 2024 and 2025. Compared to the last version, there have been several updates which have been included in this full update. One of the most important shifts has been in first-line treatment of patients with non-small cell lung cancer harboring the classical, or what we call as typical, EGFR mutation.

The current version of the recommendation is based on the updated survival data from the phase III FLAURA2 and MARIPOSA studies, based on which the panel recommended to offer either osimertinib combined with platinum-pemetrexed chemotherapy or the combination of amivantamab plus lazertinib in the first-line treatment of classical EGFR mutations. And these recommendations, as I mentioned, are grounded in the results of the FLAURA2 and MARIPOSA trials, both of which demonstrated improvement in progression-free survival and overall survival compared to osimertinib alone in patients with common EGFR mutations.

That being said, the panel actually spent significant time discussing the toxicities associated with these treatments as well. These combination approaches come with higher toxicity, longer infusion time, increased treatment frequency. So while combination therapy is now recommended as preferred, the panel has recommended that osimertinib monotherapy remains a reasonable option, particularly for patients with poor performance status and for those who are not interested in treatment intensification after knowing the risks and benefits.

Brittany Harvey: Absolutely. It's important to consider both those benefits and risks of those adverse events that you mentioned to match appropriately individualized patient care.

So then, beyond those recommendations for first-line therapy, what is new for second-line and subsequent therapies?

Dr. Sonam Puri: So this is a section that saw several major updates, particularly again in the EGFR space. The first was an update on treatment after progression on osimertinib for patients with classical EGFR mutation. Here the panel recommends the combination of amivantamab plus chemotherapy, and this recommendation was based on the phase III MARIPOSA-2 trial, which compared amivantamab plus chemotherapy with chemotherapy alone with progression-free survival as the primary endpoint.

The study met its primary endpoint, showing an improvement in median PFS with the combination of amivantamab plus chemotherapy compared to chemotherapy alone. And as expected, the combination was associated with higher toxicity. So, although the panel recommends this regimen, the panel emphasizes that patients should be counseled on the side effects which may be moderate to severe with the combination therapy approach.

In addition, a new recommendation was added for patients who are not candidates for amivantamab plus chemotherapy. In those cases, platinum-based chemotherapy with or without continuation of osimertinib may be offered, and the option of continuing osimertinib with chemotherapy was recommended and supported by data from a recently presented phase III COMPEL study, which randomized 98 patients with EGFR exon 19 deletion or L858R-mutated advanced non-small cell lung cancer who had experienced no CNS progression on first-line osimertinib, and these patients were randomized to receive platinum-pemetrexed chemotherapy with osimertinib or placebo. Although this study was small, it demonstrated a PFS benefit with continuation of osimertinib with chemotherapy, and this approach may be appropriate for patients without CNS progression who prefer or require alternatives to more intensive treatment strategies.

Next was an update on options for patients with EGFR-mutated lung cancer after progression on osimertinib and platinum-based chemotherapy. Here the panel recommended that for patients whose disease has progressed after both osimertinib and platinum-based chemotherapy, a new drug known as datopotamab deruxtecan can be offered as a treatment option. And this treatment recommendation was based on evaluation of pooled data from the TROPION-Lung01 and TROPION-Lung05 study, in which in the pooled analysis about 114 patients with EGFR-mutant non-small cell lung cancer were treated with Dato-DXd, 57% of whom had received three or more prior lines of treatment, and what was observed was an overall response rate of 45% with a median duration of response of 6.5 months. So definitely promising results.

Next, we focused on updates to subsequent therapy options for patients with another type of EGFR mutation known as EGFR exon 20 insertion mutations. In this section, the panel added sunvozertinib as a subsequent line option after progression on platinum-based chemotherapy with or without amivantamab. Sunvozertinib is an oral, irreversible, and selective EGFR tyrosine kinase inhibitor with efficacy demonstrated in the phase II WU-KONG6 study conducted in Chinese patient population. In this study, amongst 104 patients with platinum-pretreated EGFR exon 20 mutated non-small cell lung cancer, the observed response rate was 61%.

Staying in the EGFR space, the panel added a recommendation for patients with acquired MET amplification following progression on EGFR TKI therapy. In these situations, the panel recommended that treatment may be offered with osimertinib in combination with either tepotinib or savolitinib. As our listeners may know, MET amplification occurs in approximately 10% to 15% of patients with EGFR-mutated non-small cell lung cancer when they progress on third-generation EGFR TKIs, and detection of MET amplification is done with various methods, such as tissue-based methods like FISH, NGS, and IHC, as well as ctDNA-based NGS with variable cut-offs.

Over the last few years, several studies have informed this recommendation. I'm going to be discussing some of them. In the phase II ORCHARD trial, 32 patients with MET-amplified non-small cell lung cancer after progression on first-line osimertinib were evaluated, where the combination of osimertinib plus savolitinib achieved an overall response rate of 47% with a duration of response of 14.5 months.

More recently, the phase II SAVANNAH trial reported outcomes in 80 patients with MET-amplified tumors after progression on osimertinib, and in this patient population, the combination of savolitinib and osimertinib achieved an overall response rate of 56% with a median PFS of 7.4 months.

And lastly, the phase II single-arm INSIGHT 2 trial assessed the efficacy of osimertinib plus tepotinib in patients with advanced EGFR-mutant non-small cell lung cancer who had disease progression following first-line osimertinib therapy. And in this study, in a cohort of 98 patients with MET-amplified tumors confirmed by central testing, the overall response rate with the combination was 50% with a duration of response of 8.5 months. So definitely informing this guideline recommendation.

Next, we had an update on recommendation in patients with ROS1-rearranged non-small cell lung cancer. For patients with ROS1-rearranged non-small cell lung cancer, the panel recommended specifically for patients who progressed after first-line ROS1 TKIs, the addition of taletrectinib as a new option alongside repotrectinib. And this recommendation was based on analysis of the results of the TRUST-I and TRUST-II studies, which showed that amongst 113 tyrosine kinase inhibitor-pretreated patients, taletrectinib achieved a confirmed overall response rate of 55.8% with a median duration of response of 16.6 months and a median PFS of 9.7 months, a very promising agent.

Finally, for patients with HER2 exon 20 mutated non-small cell lung cancer, the panel added two new oral HER2 tyrosine kinase inhibitors, zongertinib and sevabertinib, as options in addition to T-DXd and after exposure to T-DXd. These recommendations are based on early phase data from two trials: the phase I Beamion LUNG-01 study, which evaluated zongertinib, and the phase I/II SOHO-01 study that evaluated sevabertinib. In this study, zongertinib demonstrated an overall response rate of 71% in previously treated patients, with an overall response rate of 48% amongst patients who had received prior HER2-directed ADCs including T-DXd. Sevabertinib in its early phase study showed an overall response rate of 64% in previously treated but HER2 therapy-naive patients, and an overall response rate of 38% in patients previously exposed to HER2-directed therapy. The panel believes that both agents had manageable toxicity profile and represent meaningful new options for this patient population.

Brittany Harvey: Certainly, it's an active space of research, and I appreciate you reviewing the evidence underpinning all of these recommendations for our listeners.

So, it's great to have these new options for patients in the later-line settings. And given all of these updates in both the first and the later-line settings, what should clinicians know as they implement this latest living guideline update, and how do these changes impact patients with non-small cell lung cancer?

Dr. Sonam Puri: Some great questions, Brittany. I think for clinicians when implementing this update, I think about two practical steps. First is reiterating the importance of comprehensive biomarker testing. That is the only way to identify key drivers and resistance mechanisms that we are now targeting. And second, picking a first-line strategy that balances efficacy and toxicity and patient preference for your specific patient. I think informed decision-making, shared decision-making is more important than any time right now. It has always been important, but definitely very important now.

For patients, this guideline brings recommendations on more personalized treatment options for both first-line and post-progression settings, which potentially means better outcomes. But it is also very important for our patients to continue to have informed conversations about side effects, time commitment, and what matters most to them with their providers. The panel in this version of the guideline specifically acknowledges the real-world barriers that prevent patients from receiving guideline-concordant therapy, including challenges with access to comprehensive molecular testing and treatment availability, and the panel emphasizes on the importance of shared decision-making, and we provide practical discussion points to help clinicians navigate these conversations with the patient.

In addition, the panel has also addressed common real-world clinical complexities, such as treating elderly or frail patients, managing multiple chronic conditions, considerations around pregnancy and fertility, and certain disease scenarios such as oligoprogression or oligometastatic disease. And where available, the guideline summarizes this existing data to support informed individual decision-making in these complex situations.

Brittany Harvey: Shared decision-making is really paramount, especially with all of the options and weighing the risks and benefits and considering the individual circumstances of each patient that comes before a clinician.

We've talked a lot about all of the new studies that the panel has reviewed, but what other studies or areas of research is the panel examining for future updates to this living guideline as it continues to be updated on an ongoing basis?

Dr. Sonam Puri: Yes, definitely, so much to look forward to, right? Looking ahead, the panel is closely monitoring several rapidly evolving areas that are likely to shape future updates of the guideline. This includes emerging data from ongoing later-phase studies, particularly the studies that are evaluating these new targeted agents moving to earlier lines of therapy, alongside studies evaluating additional combination strategies or more refined approaches to treatment sequencing.

We're also closely watching advances in biomarker testing, the evolving understanding of resistance mechanisms, development of new targets, and promising therapeutic agents. I think ultimately the living guideline exists to help clinicians and patients navigate this rapidly evolving field, and we would like to ensure that scientific advances are rapidly translated into better, more personalized patient care.

Brittany Harvey: Definitely. We'll look forward to those updates from those ongoing trials and future areas of research that you mentioned to provide better options for patients with non-small cell lung cancer and a driver alteration.

So I want to thank you so much for your work to rapidly and continuously update this guideline, and thank you for your time today, Dr. Puri.

Dr. Sonam Puri: Thanks so much. Thanks so much for the opportunity.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I am interviewing Dr. Joshua Reuss from Georgetown University, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer Without Driver Alterations: ASCO Living Guideline, Version 2026.3.0."

It is great to have you back on the show today, Dr. Reuss.

Dr. Joshua Reuss: Happy to be here, Brittany.

Brittany Harvey: Just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Reuss who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

Dr. Reuss, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer without driver alterations is updated on an ongoing basis. So, what prompted this latest update to the recommendations?

Dr. Joshua Reuss: Our committee is tasked with making routine updates to the living guidelines and really keeping them living, right? So, evaluating new data as it is coming in to see, is this practice changing? Is this data that should inform and potentially alter our guideline recommendations so that practitioners and other care providers could really make the best treatment decisions for their patients?

So that is something that happens on a more routine basis, but periodically, we are tasked with performing a more comprehensive update of our guideline where we really evaluate every one of our point recommendations, the data associated with these recommendations, to be sure that these are up to date, these are comprehensive, and to see if we need to alter anything in the language of these updates.

Brittany Harvey: Excellent. Thank you for providing that background. And yes, this is truly a comprehensive update that goes through all the latest literature. Given that, I would like to review what has changed and what is new in the recommendations. So, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer without driver alterations?

Dr. Joshua Reuss: So there are two main guidelines that we recommend from this panel. One is a driver mutation-positive guideline and the other is a driver mutation-negative guideline. And I think on first blush, one might look at kind of the recent flurry of approvals and new data and say, well, all the excitement, you know, is in the driver mutation-positive guideline.

But I would say that the driver mutation-negative guideline is equally as important and really has several unique challenges associated with it. You know, first and foremost is that there are really a multitude of regimens that can be considered for any one patient. And how to choose between one can be quite difficult and a stressful challenge that clinicians can have, particularly since there are really no randomized studies comparing these regimens in a head-to-head fashion.

In addition, you know, these guidelines are really broken down by two key factors. One is disease histology, so namely squamous versus non-squamous histology. And the other is PD-L1 status, broken down into one of three tertiles: PD-L1 high, which is greater than or equal to 50% expression; PD-L1 low, which is 1% to 49% expression; and then PD-L1 negative or unknown.

So what you are really looking at, if you do that math, is really six unique patient subpopulations where we need to make a recommendation on one of the multitude of treatment regimens that is approved. And what that means is you are oftentimes really looking at subset and sub-subset level data to help inform clinicians in their treatment decision making, which can be quite challenging because as those small subsets of data is more and more parsed, there are many confounders that can be interjected there. And so I think the committee is tasked with really quite a challenge in terms of how to really communicate and broadcast that data in a way that informs clinicians in making a decision on what is the right treatment for their patient.

Brittany Harvey: Absolutely. It can be challenging to interpret that subgroup data across several different studies that are reporting on different regimens and different outcomes. And I appreciate you mentioning the driver mutation-positive guideline as well. Listeners can check out the companion episode with Dr. Puri for more information on what is changed in the driver mutation-positive guideline.

Based on that primer, what is new for first-line therapy for patients with stage IV non-small cell lung cancer without driver alterations?

Dr. Joshua Reuss: Even though I will say there is not a lot of new trial data that was incorporated into this guideline, there were some updates and just some meaningful long-term data that we incorporated. I think first and foremost, there is a new top-level recommendation in this guideline pertaining to molecular testing, which is absolutely critical in both the driver mutation-positive and driver mutation-negative space. I think we tend to think that, oh, well, molecular testing really only pertains to then finding a driver mutation. But the lack of a mutation is absolutely critical as well, right? Because that is what leads us down the mutation-negative pathway.

We also need this molecular testing to assess PD-L1 status. We are seeing emerging data on molecular mutations that might confer resistance to certain immunotherapy-based strategies. So the committee felt strongly that a recommendation on molecular testing is critical to include in both the driver mutation-positive guideline and the driver mutation-negative guideline.

I will also say that we are now seeing five and six-year updates from some of the landmark trials of immunotherapy in driver mutation-negative non-small cell lung cancer. It is really incredible to see that in some of these trials, we are seeing very impressive durability of the treatment in the patient subsets that we are commenting on. In others, perhaps that durability is less clear, and I think that leads to challenges in making a recommendation on any one particular regimen. And I think that is nowhere more clear than in the squamous subset. I think that was one perhaps subtle change that is in this guideline where, particularly in the PD-L1 negative squamous population, the committee felt that no one regimen really was worthy of standing above the others.

Sometimes I think it is important to really champion one unique regimen if we feel that the data is there to support it. But I think it is equally important to list multiple regimens where the data is less clear. I think another point is that while perhaps there were no new regimens that we have added or that led to other clear changes in the prioritization of one regimen over another, there are other unique data subsets that I think come into play in making a decision and that really are important when looking at the discussion on any one recommendation from this guideline.

For example, we know there is emerging data on perhaps the significance of molecular alterations in KEAP1 or STK11 and how that might influence frontline decision-making. You know, there is not a prospective phase III trial in this population, but I think we still need to use that data in certain scenarios to make recommendations for a particular patient.

Another example of a trial that, again, did not change our recommendations, but I think one can incorporate in their decision making is the KEYNOTE-598 trial. Now, this is not a new study, but what it studied was pembrolizumab versus pembrolizumab plus ipilimumab in a PD-L1 high subset, and found that the addition of ipilimumab to pembrolizumab in the PD-L1 high population did not significantly improve clinical efficacy.

And so while pembrolizumab plus ipilimumab is not an approved regimen, it is hard to extrapolate that to our combination treatments that are approved. I think some clinicians might find that data valuable when making a frontline treatment decision on a patient who has PD-L1 high status. So a bit of a whirlwind tour, but I think there are still multiple factors that went into this guideline that are important to review when making treatment decisions for any one patient.

Brittany Harvey: Absolutely. I think what you just mentioned in having that upfront molecular testing is really key for individualized patient care. And the evidence summaries that you provide in addition to the recommendations are really important for clinicians to be able to refer to as they are making decisions in their clinic.

So then beyond those changes for first-line therapy, what is updated for second-line and subsequent therapies?

Dr. Joshua Reuss: For second-line and subsequent therapies, we did see one new treatment recommendation join these ranks, and that was telisotuzumab vedotin. Telisotuzumab vedotin, quite a mouthful. That is an antibody-drug conjugate. I like to think of that as smart chemotherapy, targeted chemotherapy, where you are trying to utilize some aspect of a marker that is selectively expressed or overexpressed on the cancer surface to then shepherd in the anticancer molecule, a highly potent chemotherapeutic in the case of currently approved antibody-drug conjugates, to exert antitumor killing effect.

So in this case, the antibody-drug conjugate telisotuzumab vedotin targets MET overexpression. So telisotuzumab is an antibody targeting MET, and that is conjugated to an MMAE highly potent chemotherapeutic payload called vedotin. So we know MET can be selectively expressed and overexpressed in non-small cell lung cancer in both driver mutation-positive and mutation-negative subsets.

The data that led to this approval was from the phase II LUMINOSITY trial which evaluated telisotuzumab vedotin, or Teliso-V, in many subsets. But the subset that really showed promise and was expanded was the EGFR wild-type, non-squamous, non-small cell lung cancer population with MET overexpression. And so in 78 patients with high levels of expression, the response rate here was 34.6%, median progression-free survival of 5.5 months, and a median overall survival of 14.6 months. With an overall acceptable safety profile; grade 3 or higher adverse events, neuropathy was perhaps the most common at 7%, also increased ALT at 3.5%, and pneumonitis at 2.9%.

Now this was phase II data that led to an accelerated approval. There is an ongoing phase III study randomizing patients with high expression to Teliso-V versus docetaxel. That is the phase III TeliMET study. But it is nice that we now have another option for patients, perhaps a more biomarker-directed option with, again, this MET overexpression. And again, it further reinforces the importance of molecular testing in patients with traditionally driver mutation-negative non-small cell lung cancer, whether that is upfront or at progression, and in particular utilizing immunohistochemistry to assess MET expression in these patients.

And this does join another ADC that we had previously made an update in our recommendation, which is trastuzumab deruxtecan, which is approved for those patients with HER2-overexpressing non-small cell lung cancer. So just again to reiterate the importance of molecular testing in patients both at the outset of their treatment and upon progression on frontline therapy.

Brittany Harvey: Definitely. It is great to have this new antibody-drug conjugate join the treatment options, and as you mentioned, very important in this case to have that molecular testing done at the outset and at progression.

So then in your view, what should clinicians know as they implement this living guideline, and how do these changes impact patients with non-small cell lung cancer?

Dr. Joshua Reuss: Because there are so many different regimens that one can consider for any one patient, I think it is easy to become overwhelmed and stress on, "Am I making the right choice for my patient?" And I think one of the key take home points is that in many cases, there is no one right regimen. And I think one has to weigh several factors. It is the treatment schedule. It is the toxicity profile. It is the molecular profile of the patient. It is the patient preference. You know, there are so many factors here.

And I would like to draw the reader and viewer's attention to an important section of these guidelines, particularly the Patient and Clinician Communication section, where we have a box focused on discussion points between patients and clinicians, which I think focuses on several of the high-level points that one can emphasize in making these decisions, ranging on things from: what are the goals of the treatment? What are the risks and benefits to any one approach? What are comorbidities that should be factored in? Common concerns, toxicity management, clinical trial consideration. All of these factors that I think are incredibly important in making that frontline treatment decision and implementing a regimen that both the clinician and, more importantly, the patient feels comfortable with.

Brittany Harvey: It is really important that there is shared decision-making in these scenarios. And I think that patient-clinician communication section can tease out some of those preferences from the patient end and talk through the risks and benefits of different regimens as well.

As we mentioned at the top of this episode, this guideline is a living guideline and updated on an ongoing basis. So what is the panel examining and keeping an eye on for future updates to this guideline?

Dr. Joshua Reuss: So I think there are a lot of exciting new therapies and more up-to-date trials that we are anxiously awaiting the results of on our committee, and I think the oncology community in general is awaiting the results of. When we will have these results, I think, is a bit of an open-ended question, but I can give some insight on several of the trials that our committee is really keeping a close eye on.

One that we have mentioned for several guideline iterations is the ECOG-ACRIN INSIGNA trial. This is a phase III clinical trial comparing pembrolizumab versus pembrolizumab plus carboplatin and pemetrexed chemotherapy in PD-L1 positive, non-squamous, non-small cell lung cancer. We talk about there being different regimens that can be considered in PD-L1 positive and PD-L1 high subsets, namely immunotherapy alone or immunotherapy plus chemotherapy, but there is no direct head-to-head comparison here. So this trial hopefully will answer that question. It has now finished accrual.

There are other very interesting molecules and trials. I think another interesting compound is ivonescimab. This is a PD-1/VEGF bispecific antibody that is currently approved in China as monotherapy in patients with PD-L1 positive non-small cell lung cancer based off of the HARMONi-2 trial, where the progression-free survival of this bispecific antibody, ivonescimab, appeared superior to pembrolizumab. And we are looking closely at ongoing trials to see if these results will be replicated in an ex-China population. And if so, I think it could have a real impact and change on our guidelines.

Still other very interesting things. There are obviously confirmatory studies for antibody-drug conjugates, such as the TeliMET study that I alluded to earlier, and many promising antibody-drug conjugates, both bispecific and trispecific antibody-drug conjugates, that hopefully can inform practice.

And then there are several unique subsets of populations that I think we now are utilizing data on to make decisions, but a lot of that is retrospective in small subsets where we do not have that prospective data. And there are several trials ongoing in some of these subsets to try to gain clarity on what regimen may be the best for patients.

One example is the phase III TRITON trial, which is looking at comparing CTLA-4 containing regimen, particularly the POSEIDON regimen of durvalumab plus tremelimumab and chemotherapy, versus the KEYNOTE-189 regimen, which is pembrolizumab plus carboplatin and pemetrexed, in patients with non-squamous, non-small cell lung cancer that have alterations in either KRAS, KEAP1, and/or STK11. There is a lot of both preclinical and clinical data to suggest that patients with these alterations in STK11 and KEAP1 may be more resistant to a PD-1 based treatment approach, and perhaps the incorporation of CTLA-4 can lead to a more meaningful response in this unique subset. Obviously, that data, it is retrospective, it is in small subsets. And when you add in a CTLA-4 molecule, you are also introducing greater risk for toxicity. So this trial is going to be very important in elucidating: is there a benefit in that unique subset? Does that data that we see retrospectively in this small subset hold true when evaluated in a prospective fashion?

So while our guideline, our most recent comprehensive panel update, may not have had a lot of new data in it that has influenced frontline treatment decision-making, I think the future is bright and there are a lot of novel studies and novel treatments on the horizon that will hopefully improve the outcomes for our patients.

Brittany Harvey: Absolutely. We will look forward to the results of those ongoing trials to provide more options and particularly clarity for patients with non-small cell lung cancer and to inform this guideline and its many updates to come.

So I want to thank you so much for your work to rapidly and continuously update this guideline, and thank you for your time today, Dr. Reuss.

Dr. Joshua Reuss: Thank you so much.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I am interviewing Dr. Mary-Ellen Taplin from Dana-Farber Cancer Institute, lead author on "Systemic Therapy in Patients With Metastatic Castration-Resistant Prostate Cancer: ASCO Living Guideline, Version 2026.1."

Thank you for being here today, Dr. Taplin.

Dr. Mary-Ellen Taplin: Thank you, Brittany. It is a pleasure.

Brittany Harvey: Before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Taplin who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

To dive into the content here and what we are here today to talk about, this living clinical practice guideline for systemic therapy for patients with metastatic castration-resistant prostate cancer is updated on an ongoing basis. Dr. Taplin, what prompted this latest update to the recommendations?

Dr. Mary-Ellen Taplin: Thank you, Brittany. Several things prompted the latest update. There have been several phase III trials that have been practice-changing that have resulted in the last several years that needed to be added to the guidelines to inform clinicians of comprehensive treatment options.

Brittany Harvey: Great, and it is great to have this updated guideline for readers. I would like to review the changes to the recommendations in this latest iteration across the patient populations that are outlined in the guideline.

So, starting with: What are the updated recommendations for patients previously treated with androgen deprivation therapy alone whose disease has progressed to metastatic castration-resistant prostate cancer?

Dr. Mary-Ellen Taplin: A nice feature of this guideline is that in addition to the tables, which provide detailed options, is at the end of the guidelines, our readers will find very clear algorithms that describe past treatment scenarios that patients could have had and then outline their treatment options. So it is very clear. Our clinicians will love these algorithms.

And one of the changes for the disease state that you mentioned, which is the least treated castration-resistant state of prostate cancer which is previously treated with ADT alone, is that we recommend testing for mutations in the HRR, homologous recombination repair, genes. And the ones that are specifically known and applicable to prostate cancer are the BRCA genes. So there is clear recommendation of testing to remind us, as treating physicians, that now is the time, if it hasn't been done before, to institute both germline and somatic testing. And somatic testing, if it can be done on tissue, is preferable, but if not, the liquid biopsy approaches, the ctDNA approaches, have now advanced to the point that most patients with metastatic prostate cancer will be able to successfully have testing on the liquid biopsies.

So that is number one, testing. And then the new treatment options include, if a patient does have an HRR gene alteration, and maybe about 20-25 percent of patients will be in that category, the combinations of an androgen pathway inhibitor and a PARP inhibitor are now treatment options. So for instance, talazoparib and enzalutamide; olaparib and abiraterone; or niraparib and abiraterone are some of the newer treatment options if the patient is HRR-positive.

So, Brittany, in regard to patients treated with ADT alone, another new treatment option is the combination of radium-223 with enzalutamide. This is data based on the PEACE-3 trial which did show both an rPFS and OS benefit. For the patient who is HRR-negative and has previously not had an ARPI, just ADT alone, the combination of radium and enzalutamide is a new recommendation added to the algorithm.

Brittany Harvey: Great. Thank you for reviewing those options for that patient population. And as you mentioned, I think those algorithms are very helpful as figures in the document. They are clear and can be used as at-a-glance tools for clinicians in their busy clinics.

So then the next patient population that the guideline addresses: What is new for patients previously treated with androgen deprivation therapy and an androgen receptor pathway inhibitor whose disease has now progressed to metastatic castration-resistant prostate cancer?

Dr. Mary-Ellen Taplin: Right, so there are several new treatment options. So one is lutetium-PSMA-617, the trade name of which is Pluvicto. So that has now been FDA approved to use after progression on an AR pathway inhibitor and prior to the use of docetaxel chemotherapy.

Brittany Harvey: Thank you for reviewing that new option for patients treated with androgen deprivation therapy and an ARPI whose disease has progressed.

So then moving into the next set of recommendations, what does the panel now recommend for patients previously treated with androgen deprivation therapy and docetaxel whose disease has progressed to metastatic castration-resistant prostate cancer?

Dr. Mary-Ellen Taplin: The next group of patients is those treated with ADT and docetaxel but haven't had an AR pathway inhibitor. Treatment options, again the HRR testing is important. So all patients with metastatic castration-resistant prostate cancer should be considered for both germline and somatic testing. I will repeat that. And if they are BRCA mutation positive, then the option of talazoparib and enzalutamide; olaparib and abiraterone; and niraparib and abiraterone.  So the AR pathway inhibitors plus the PARPs. There are three choices, so that can be somewhat complicated to think through, but most practitioners will get familiar with one of those combinations and be their go-to.

So those are for BRCA-positive or HRR-positive. The talazoparib/enzalutamide trial also included non-BRCA HRR-positive gene mutations. And if they are HRR-negative, the option that we discussed above of radium and enzalutamide is new to the guideline.

Brittany Harvey: Great. And then the last category of patients that is addressed in this update: What has changed for patients previously treated with androgen deprivation therapy, an androgen receptor pathway inhibitor, and docetaxel whose disease has now progressed to metastatic castration-resistant prostate cancer?

Dr. Mary-Ellen Taplin: Well, in this space, patients who are heavily pretreated with ADT and ARPI, one or even two, and chemotherapy, generally with docetaxel, the recommendations are not new within the last year or two. And they include Pluvicto; a PARP inhibitor if HRR-positive and they have not had one; second-line chemotherapy such as cabazitaxel. And if they are a very rare group and they have been sequenced and they are MSI-high, then considering a PD-1 inhibitor such as pembrolizumab can be considered. I will note that this is a very small percentage of mCRPC patients, probably in the order of 5 percent or less.

Brittany Harvey: Understood. And I appreciate you reviewing the recommendations across all of these patient populations. It sounds like some of the key points is that HRR testing is very important for this patient population, and that the algorithms and the tables in the manuscript provide the full list of options that clinicians and patients can refer to.

Dr. Mary-Ellen Taplin: Those are the highlights. And I will note in the tables, all the sections have "Special Considerations" sections because patients never fall into the black and white of one category. And those practical information or special situations sections of each of the recommendations can also help clinicians think about the individual patient in front of them and how they might choose one therapy over another since there are generally choices in all of these treatment situations.

Brittany Harvey: Absolutely. That information for the individualized patient-clinician decision-making is really key when, as you said, there is a list of options to choose from.

So in your view, what should clinicians know as they implement this living guideline update, and how do these changes impact patients?

Dr. Mary-Ellen Taplin: I am so excited about this living document. ASCO has invested to developing the software to, in real time and iteratively, assess the new data that is published in prostate cancer and other diseases. So now we don't have to wait many years for the next guideline to come out. The guidelines will be updated every six months in prostate cancer based on this automatic search of the literature and a standing panel of both academic and community experts in prostate cancer treatment. So we no longer have to wait.

That is what makes this guideline stand out to other guidelines. And in the digestible format that we have made, a clinician can seek out the table and read some details, seek out practical information for the recommendations, or they can just go right to the clear figure algorithm and take a quick snapshot. "Yep, I need to do HR testing. Done. Oh, okay. HR-positive or negative, these are my options," and then think about the individual patient in front of them when there is more than one option. For instance, a patient with cardiovascular history, abiraterone might not be a good choice for them. Or a patient with neuropathy, docetaxel might not be a good choice for them. But, within this guideline, it really will be up to date and focused on the busy clinician and knowing what the options are for their patient.

Brittany Harvey: Definitely. This new era of living guidelines is very exciting and can provide even more up-to-date, evidence-based recommendations to really support clinicians and patients with metastatic castration-resistant prostate cancer.

So in that vein, finally, what is the panel examining, and what are you excited for for new data coming out for future updates to this living guideline?

Dr. Mary-Ellen Taplin: The future updates will depend on the results of phase III clinical trials. You know, there are many phase III trials ongoing in advanced prostate cancer, some of which include targeted therapy, which has been long awaited in prostate cancer. So such compounds as antibody-drug conjugates that are targeting certain proteins in prostate cancer cells, such as STEAP1, KLK2, B7-H3.

So I think we are entering a new era in prostate cancer where we will be targeting cells and delivering drugs and applying them to prostate cancer if the trials are positive. So I think with AI and a large investment in prostate cancer clinical drug development, I think the treatment options for our patients will be rapidly evolving in a manner not previously seen. So the guidelines need to follow along with these developments.

Brittany Harvey: Definitely. It sounds like an exciting time for research in metastatic castration-resistant prostate cancer. And we will await the result of those phase III trials to inform this guideline and lead to future updates.

So I want to thank you so much for your work to rapidly and continuously update these guidelines and for your time today, Dr. Taplin.

Dr. Mary-Ellen Taplin: Oh, it was my pleasure. ASCO has been a leader in this area, and as a practicing clinician, we are thankful for the investment and guidance that ASCO gives us.

Brittany Harvey: Absolutely.

Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I am interviewing Dr. Lisa Hicks from St. Michael's Hospital and University of Toronto, and Dr. Joseph Mikhael from the Translational Genomics Research Institute, an affiliate of City of Hope Cancer Center, co-chairs on "Treatment of Multiple Myeloma: American Society of Clinical Oncology-Ontario Health (Cancer Care Ontario) Living Guideline."

Thank you for being here today, Dr. Hicks and Dr. Mikhael.

Dr. Lisa Hicks: Thanks so much.

Dr. Joseph Mikhael: It is a pleasure to be with you, Brittany. Thank you.

Brittany Harvey: Before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Hicks and Dr. Mikhael who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

So then to dive into what we are here today to talk about, Dr. Mikhael, I would like to start by recognizing that this guideline updates the 2019 ASCO-CCO Guideline on the Treatment of Multiple Myeloma. So what prompted this update and what is the scope of this updated guideline?

Dr. Joseph Mikhael: It is amazing when we think back in myeloma years, 2019 actually seems a very, very long time ago because really so much has changed in myeloma over these last six to seven years. Indeed, there have been over 150 randomized controlled trials that we didn't have at the prior guideline that we reviewed for this. Myeloma is a disease that has really changed so dramatically over these last several years. Multiple new agents have been introduced. We now have CAR-T cell therapy, bispecific antibodies, and multiple other agents that were not available at the time.

Furthermore, with this growing complexity, it is becoming more important than ever to be able to provide practical advice and guidelines to the oncology community. For most oncologists, they have less than 5% of their time dedicated to multiple myeloma. It is important to bring a clarity to them that allows them to care for their patients. And the scope of these guidelines, furthermore, really cover the whole spectrum of myeloma. They go further than our prior guideline where now we have included smoldering multiple myeloma along with frontline therapy and relapsed multiple myeloma. So, we have really tried to provide the full spectrum to our colleagues in oncology to ensure that they have the tools they need to provide the best care possible for their patients.

Dr. Lisa Hicks: That is a really terrific summary. And maybe one thing I will just add is it is really unique to have this much literature. I can't think of another guideline that I have ever been involved with that has seen a field move so quickly and develop so many advancements in a period of just over four or five years.

Brittany Harvey: Certainly, there is a large volume of evidence that you all had to review for this guideline update. I think to your point probably one of the greater volumes of literature for a guideline update that you both mentioned.

Based on that, I would like to review the key recommendations that are updated in this guideline. So Dr. Hicks, that new patient population that Dr. Mikhael mentioned earlier, what are the key recommendations for patients with smoldering multiple myeloma?

Dr. Lisa Hicks: So this is the first time that an ASCO guideline is addressing this branch of multiple myeloma care. It is an area where I think some guidance is needed, and smoldering myeloma is not an active cancer. And so one thing that I really want to highlight is that the panel felt very strongly that to recommend any therapy in this space we needed a higher level of evidentiary certainty, of evidentiary confidence, to make recommendations for active therapy.

The panel really made two very important recommendations. First of all, the panel did not recommend treatment for low or intermediate risk smoldering myeloma. That is important. And then the area where I think for the first time we have recommended consideration of treatment is patients with high risk smoldering myeloma. And for patients with high risk smoldering myeloma, the panel recommended that it was appropriate to consider either treatment with daratumumab or careful observation.

Dr. Joseph Mikhael: And I think that move forward as you have mentioned, Dr. Hicks, is particularly important because it is an area to some degree still of equipoise and many trials are going on in the area. But we do now have a strong phase III trial that supports the use of daratumumab monotherapy for three years when compared to close observation. But of course, that is not for everyone. And one of the key themes of all of our recommendations are going to be now that more and more choices are available, that we have discussions with our patients to ensure that we match the right treatment with the preference of the patient. And I think that is particularly important here in smoldering myeloma.

Dr. Lisa Hicks: Multiple myeloma care and the multiple myeloma evidence is really so nuanced, and one of the nuances that readers will appreciate if they read the guideline is that how smoldering myeloma is risk stratified has been different across different trials. And that really adds to the complexity of this recommendation and is one of the reasons that the panel felt that it was appropriate to recommend either observation or treatment.

Brittany Harvey: It is great to have these new recommendations for this unique patient population. And as you both mentioned, that individualized patient care is really important across this entire guideline.

So then following those recommendations, Dr. Mikhael, what is recommended for initial therapy, autologous stem cell transplantation, post transplant therapy, and measurement of response for patients with transplant eligible multiple myeloma?

Dr. Joseph Mikhael: Well, that is an area that has really considerably also grown since the last guideline. Obviously one would have to consult the guidelines to get every last detail, but in essence, we want to assess whether or not patients are transplant eligible or ineligible. And that assessment is not based on age or renal function alone, but indeed on a careful assessment of that patient.

When that assessment is made and deemed that a patient is transplant eligible, our recommendation is that a patient typically would receive a quadruplet. That is to say, a monoclonal antibody directed against CD38, a proteasome inhibitor, an immunomodulatory drug, and dexamethasone to be given for approximately four to six cycles followed by the stem cell transplant, followed by potentially another two cycles of consolidation, and then maintenance therapy.

A couple of important caveats. One, we do have two different CD38 antibodies that can be used, either daratumumab or isatuximab. Although typically bortezomib is the preferred proteasome inhibitor, consideration can be given to carfilzomib by virtue of the potential toxicity from bortezomib. And then lastly in the maintenance setting, we are typically recommending at least lenalidomide alone, but consideration can be given to dual maintenance therapy as the data is emerging to either add to that daratumumab or carfilzomib. All the while using the IMWG criteria for response. The goal of course is to achieve the deepest response possible and to maintain that response until such time as patients would relapse.

Finally, the length of maintenance therapy continues to be an area of equipoise and study in multiple myeloma. And so at minimum, patients would receive two to three years of maintenance therapy, and based on risk status and depth of response it can be considered that patients would potentially come off maintenance therapy, of course always with the caveat that toxicity would influence length of therapy as well.

Brittany Harvey: Yes, as you mentioned, evaluating which patients are eligible is extremely important for considering what is recommended in the guideline for both transplant eligible and transplant ineligible patients.

So then Dr. Hicks, following those recommendations for transplant eligible multiple myeloma, what are the recommended treatments, goals of therapy, and measurement of response for patients with transplant ineligible multiple myeloma?

Dr. Lisa Hicks: You know, I really can't emphasize enough how important an individualized patient assessment is. When we are thinking about the range of patients that are included in this category of transplant ineligible patients, it is a huge range. You may have fairly fit patients in their late 70s all the way to patients in their 90s. And we really want to see that treatments are tailored both to the fitness of the patient, their individual circumstances, and their preferences. And it is a wonderful thing to have lots of options for patients in this circumstance.

What the guidelines have recommended for most patients who are transplant ineligible but fit enough for a stronger therapy is quadruplet therapy. So actually therapy that is very similar to what is being recommended in the transplant eligible population but for a longer period of time. And then for those patients who for whatever reason, be it their fitness or their preference, are not appropriate for that quadruplet therapy, the recommendation is for triplet therapy with a combination of lenalidomide, bortezomib, dexamethasone, or very often, more often in most cases, an antibody based approach with an anti-CD38 plus lenalidomide plus dexamethasone.

Dr. Joseph Mikhael: The only thing I would add to that, I think we have to also, as we do mention in our recommendations, be particularly cautious with the dosing of these medications. Because even though we think of them as a single agent or a particular class, there can be quite a variation within the dosing regimen that can affect a patient's side effects and their quality of life. And so being very careful with dose modifications, and particularly in the transplant ineligible patient, is an important part of the recommendation as well.

Dr. Lisa Hicks: Yeah, this is a podcast so no one can see me nodding vigorously that dose modification is so important particularly with those older and frailer patients, and with particular attention to trying to reduce dexamethasone doses and favoring weekly administration of bortezomib when that drug is used.

Brittany Harvey: Absolutely. Considering the risks and benefits and patient preferences is really key to selecting therapy for these patients.

So then Dr. Mikhael, for the final overarching patient population addressed in this guideline, for patients with relapsed or refractory multiple myeloma, what treatment options are recommended?

Dr. Joseph Mikhael: This of course is, if you will, the biggest part of the guideline because there has been so much done in the relapse setting. And I think we start the guideline by saying a decision has to be made as to when to institute therapy. That there may be some patients with slow biochemical relapse that may be monitored for a period of time. But when the decision is made to initiate treatment, instead of a simple algorithm, the guideline emphasizes the fact that there are multiple choices that can be given to a patient that are going to match what comorbidities the patient has, what they have been treated with before, and of course what their preferences are.

I think we highlight two particular areas. That now that CAR-T cell therapy is available as early as first relapse, it should be a consideration by virtue of the fact that it has resulted in such deep and durable responses. But that triplets should also be considered in that earlier relapse setting because we do have multiple classes of agents that can be used. We know that in later relapse options exist including bispecific antibodies for which we have four different choices. And that in general, patients will ultimately receive either a triplet or CAR-T cell therapy in earlier relapse, but there are some patients who may be eligible only for a doublet by virtue of their comorbidities and of their prior therapies.

Lastly, it really does emphasize the point as we have mentioned a few times in this podcast, and I am so glad it keeps coming up, is that as I often say we don't treat myeloma, we treat people. And engaging the patient in that conversation to ensure that the right treatment gets matched to the right patients is particularly important because with all the new classes that we have with antibody drug conjugates, with XPO1 inhibitors, the traditional three classes of proteasome inhibitors, immunomodulatory drugs, monoclonal antibodies, along with as we have already mentioned CAR-T and bispecific antibodies, it really is an incredible laundry list of choice. And making that choice specific to the patient becomes absolutely critical.

I should also lastly note that there are patients who may defer their initial transplant. There may be patients who may be eligible for a second transplant. So autologous stem cell transplant, although primarily used in the frontline setting, may still be a consideration for a smaller subset of patients in the relapse setting.

Dr. Lisa Hicks: I think maybe one thing that I would add is an overarching principle which is actually similar to a principle in the first guideline, and that is that in the relapsed or refractory setting, there are many different treatment options. And in fact, the number of treatment options feels like it is evolving every day. But an overarching principle for clinicians to consider is to try and choose combinations of drugs that the patient has either not been exposed to in the past or certainly that they are not refractory to. We really want to be pulling new options out of the toolbox as much as we can.

Dr. Joseph Mikhael: Very often we do see where someone may be on a triplet and they are progressing on it and someone just changes out one drug. We have suggested not to take that approach but to take the approach of completely introducing a new therapy when someone is progressing on their current therapy. I think that point is particularly important and the consensus panel was very clear.

Brittany Harvey: Understood. That is very helpful when thinking about what options to offer to patients in the relapsed and refractory setting. And as you mentioned earlier, the figures in this guideline provide an outline of options and then the tables really go into some of the details and outcomes of the trials, and those are very helpful for clinicians to refer to.

So then Dr. Hicks, we have talked a little bit about some of the nuances of the guideline, but what should clinicians know as they implement these new and updated recommendations?

Dr. Lisa Hicks: I think they should feel comfortable that these are trustworthy guidelines. So these are evidence-based guidelines that have been rigorously developed after a very thorough evidence review and put together by a panel of experts who were extremely thoughtful in their review of the evidence. And so all of this contributes to the trustworthiness of the guidance.

And then I would also encourage people to take a deep look at the guidelines because of the importance of nuance that is addressed in them, and then to also explore some of the tools that ASCO is developing that helps with implementation including the flow charts that are contained within the guidelines and some additional tools that are available online.

Brittany Harvey: Absolutely. The tools and resources for this guideline are available online with the publication and we will provide links to that in the show notes of the episode.

So then following that, Dr. Mikhael, how does this guideline update affect patients with multiple myeloma?

Dr. Joseph Mikhael: As we sort of intimated earlier, I like to say I don't treat myeloma, I treat people. I think we should always be patient-centric and patient-focused. And I think in the discussion we always were. We always wanted to ensure that multiple factors go into a decision-making process. We are not just looking at the biology of the disease, we are looking at patient factors. Those patient factors include their frailty as we commented in a frailty assessment, their preferences, their comorbidities.

And I think, in a day where we have so many choices, we emphasize in the guideline the importance of that conversation with the patient. That, if you will, shared decision-making model where options are laid out and based on the patient factors and the treatment factors they can then be meshed together in the best way so that patients can make the right choice.

And of course in conjunction with the guidelines, we have patient friendly summaries of them. And we involved, of course, patients in the development of these guidelines. And I think that is one of the greatest strengths of the ASCO guidelines is that there is a patient with us at the table who is giving their perspective on the guideline as we go forward. So I am very thankful that we have created a product that is, if you will, not only for the providers, the practitioners that are prescribing these agents and that are directly giving the care, but indeed for the very patients who of course have the most at stake here.

Dr. Lisa Hicks: Yeah Joe, I am so glad you called out the participation of patient partners in the guideline. It is such an important part and they were really- the patient partner was such an important part of this panel in helping us understand the patient perspective as we developed this guidance.

Brittany Harvey: Definitely. It is a hugely important role for the panel and for all of the panel including the patient partners and the experts in the disease to review the evidence and come up with comprehensive recommendations. And yes, as you mentioned, the individualized treatment and the shared decision-making is really paramount to this guideline.

Finally, Dr. Hicks, you alluded to earlier the vast number of treatment options that is really exploding in multiple myeloma. And so this guideline is becoming a living guideline continuously updated by ASCO. So what are the outstanding questions regarding this topic and what evidence is the panel looking forward to for future updates?

Dr. Lisa Hicks: I am really excited about this. This is one of the first guidelines that will be a living guideline for ASCO and it is such a good fit. You have heard Joe and I say a few times how quickly this field is moving, how complex the field is. I think everyone on the panel knew that no matter how quickly we did it and how deeply we reviewed the evidence, it was inevitable that more evidence would be generated as we were putting out the guideline.

In a field like that, it is really important that we find a way to provide evidence-based guidelines quickly to the community. You know, waiting another five years, letting another 150 trials accrue before we do another guideline is not what the community needs. And so ASCO has really risen to this challenge and is committed to living guidelines.

And so a living guideline is a guideline that commits to reviewing the evolving evidence on an ongoing basis, watching for practice changing trials, and having a standing panel that will review evidence and update recommendations on a regularly scheduled basis. So that is what a living guideline is, and that is what this guideline is becoming. That is just the first thing in terms of what a living guideline is.

And then what are we watching? Well, honestly what aren't we watching? There is so much happening in multiple myeloma. We knew as we put the guideline out that there were trials in process, some trials that had been released at conferences but not yet published. We will be waiting for those and if they are practice changing they will be addressed in upcoming updates. There is new evidence just recently presented around combined anti-CD38 and bispecific antibodies. I don't know yet whether that will be addressed but I wouldn't be surprised if it was. There are so many things coming down the pipeline and it is just wonderful that there is going to be a way to try and address them in a robust fashion.

Dr. Joseph Mikhael: Yeah I agree with you, Lisa. I can't think of another disease that would be more relevant for a living guideline. I mean we had difficulty because new data kept coming in as we were making recommendations. And so at some point we had to draw a line and say this is where we will stop and produce this guideline and have it ongoing. And I really look forward to seeing the updates because we know as you mentioned that there are so many things that are on the verge of approval and on the verge of changing the way we manage this terrible disease.

And before I close, I would love to remind all of our listeners that as we commented from the start, patient engagement is critical at ASCO and in our guidelines process. Unfortunately we lost a very dear patient during the guidelines process, and that is Jack Aiello. Jack Aiello had been a patient and a patient advocate for many, many years in the myeloma community. And indeed we have actually dedicated these guidelines to his honor. And so I thought it would be valuable for us to mention that today. And we miss you Jack, but we are very grateful that we have been able to dedicate this excellent body of work to your memory.

Brittany Harvey: Absolutely. This guideline and your dedication to him is an honor to his memory and we really recognize him in thinking about this guideline.

We will look forward to those future trial results that you mentioned, Dr. Hicks, to update this guideline and continue to provide options for patients with multiple myeloma and improve upon those options and shared decision-making with patients.

So I want to thank you both for all of your work to develop this guideline and for your time today, Dr. Hicks and Dr. Mikhael.

Dr. Lisa Hicks: You are so welcome. Thanks for featuring this guideline.

Dr. Joseph Mikhael: Thank you so much, Brittany. It has been a privilege.

Brittany Harvey: Hello and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts.

My name is Brittany Harvey, and today I am interviewing Dr. Alison Loren from the Perelman School of Medicine of the University of Pennsylvania and Dr. Ann Partridge from Dana-Farber Cancer Institute, co-chairs on "Management of Cancer During Pregnancy: ASCO Guideline." Thank you for being here today, Dr. Loren and Dr. Partridge.

Dr. Alison Loren: Thanks for having us.

Dr. Ann Partridge: It's a pleasure.

Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Partridge and Dr. Loren who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes.

So then to dive into the meat of this guideline, to start us off, Dr. Loren, could you provide an overview of the scope and purpose of this new guideline on the optimal management of cancer during pregnancy?

Dr. Alison Loren: Sure, thanks, Brittany. So this was really born out of I think a lot of passion and concern for this really vulnerable patient population. We have observed, and I am sure it is not any surprise to your audience, that the incidence of cancer in young people is increasing. And simultaneously, people are choosing to become pregnant at older ages, and so we are seeing more and more people with a cancer diagnosis during their pregnancy. And for probably obvious reasons, there is really no way to do randomized clinical trials in this population. And so really trying to assemble and articulate the best evidence for safely managing the diagnosis of cancer, the management of cancer once it is confirmed, being thoughtful about obviously the health of the mom, but also attending to potential risks to the developing fetus, and really just trying to be really comprehensive and balanced about all the choices for these patients when they are facing some really challenging decisions in a very emotionally fraught environment. And I think it is really emotionally fraught for the providers, too. You know, this is obviously an extremely intense, very emotional set of decisions, and so trying to provide a rudder essentially to sort of help people frame the questions and trying to make as evidence-based a set of recommendations as possible.

Dr. Ann Partridge: And I would just add that "evidence-based" is a strong word here because typically our, as you just heard, our gold standard evidence is a randomized trial, but you can't do that in this setting, in general. And so, what we were able to do with the support of the phenomenal ASCO staff was to pull together kind of the world's literature on the safety and outcomes of treatments during pregnancy, as well as consensus opinion. And I think that is a really, really critical difference about this particular guideline compared to many of the other ones that ASCO does, where consensus and good judgment needed to kind of rule the day when evidence is not available. So, there is a lot of that in our recommendations.

Dr. Alison Loren: That is such a good point. And I just, before we move forward, I just want to reflect that the composition of the panel was really broad and wide-ranging. We had maternal medicine specialists, we had legal and ethical experts, we had representatives who understand pharmaceutical industries' perspectives, and then medical oncologists representing the full spectrum of oncology diagnoses. And so it was a really diverse, in terms of expertise, panel, internationally composed to try to really get the best consensus that we could in the absence of gold standard evidence.

Brittany Harvey: Absolutely. That multidisciplinary panel is really key to developing this guideline and, as you said, looking at the evidence and even though it does not reach the level of randomized trials, still critically evaluating it and reviewing that along with consensus to come up with optimal management for diagnosis and management of cancer during pregnancy.

So then to follow that up, I would like to next review the key recommendations of the guideline across the main sections that the expert panel provided. First, I will throw this out to either of you, but what are the important general principles for the management of cancer during pregnancy?

Dr. Ann Partridge: I think there were three major principles that we hammer home in the guidelines. One is that this is a team sport. It is multidisciplinary care that is necessary in order to optimize outcomes for the patient and potentially for the fetus. And that you really need to, from the beginning, bring in a coordinated team, including not just oncologists but obstetricians, maternal-fetal medicine specialists, neonatologists, ethics consultants, and obviously the patient and potentially her family. So that, I think, is one of the most important things.

Second would be that obviously in a pregnancy, there are two potential patients and that the nuances of safety and risk from treatment is really wrapped up in where in the trimester of the pregnancy the patient is diagnosed, along with the kind of cancer that it is, both the urgency of treatment and the risk of the cancer, as well as the potential risks of any given intervention across the cancer continuum. It is a broad guideline in that regard.

And then finally, and this is particularly timely given what is going on from a sociopolitical standpoint in the U.S., really thinking about informed consent and potential ethical as well as legal implications of some of the choices that patients might have when they are thinking about, in particular, continuing a pregnancy or potential termination.

Dr. Alison Loren: And I will just add that I think that the key to all of this guidance is nuance and individualization and also making sure that patients and their care providers understand all the choices that are available to them and also the consequences of those choices. You know, nobody would choose to receive chemotherapy during pregnancy if that wasn't necessary. So there are risks to treatment, but there are also risks to not treatment. And making sure that in a suboptimal situation where you do not have a lot of evidence, trying to weigh, the best you can, the risks and benefits of all of the choices so that the patient can come to a decision about the treatment plan that is right for her.

Brittany Harvey: Definitely. And those core concepts really set the stage for individualized care on what is necessary for appropriate multidisciplinary care, prioritizing both patient autonomy and informed decision making.

With those core concepts and key principles in mind, I would like to move into the recommendations section of the guideline. So what are the key recommendations regarding diagnostic evaluation for pregnant patients with signs or symptoms of cancer?

Dr. Alison Loren: I think the most important thing is to not delay, that there are very careful and well-thought-out recommendations for how to evaluate a potential cancer. And while there are certain things that we know can be harmful, particularly when certain dose thresholds are exceeded - for instance, abdominal imaging, there are certain radiographic thresholds that you don't want to exceed because of risk of harm to the embryo or fetus - there are still lots of options for diagnosing cancer during pregnancy. And again, thinking about the costs of not doing versus the cost of doing, right? It is really important to make the diagnosis of cancer if that is a consideration or a concern. And sometimes going directly to biopsies or getting definitive studies, even if there is a small risk to the developing fetus, is really essential because if the mom does not survive, of course, the fetus is also not going to survive. And so we need to be thinking first about the patient who is sitting in front of us, the woman who needs to know what is going on in her body so she can make good decisions about her health. So, I think that is a key principle in thinking about this.

Brittany Harvey: Absolutely. So, following that diagnosis of a new or recurrent cancer, what is recommended for oncologic management of patients who are diagnosed with cancer during their pregnancy?

Dr. Ann Partridge: So, I think the general principle is, again, cancer is such a wide number of diseases and even within diseases, a range of stages and risks and associated opportunities for risk reduction and/or treatment depending on the type of cancer. Just by example, in the work that I do, which is breast cancer, once someone has had a surgery in the early-stage setting, a lot of our treatment is about risk reduction. And that is very different than from what Alison does, which is treating people with leukemia, where it is kind of binary. If you do not treat, including with cytotoxic drugs, the patient and an unborn fetus will die, especially early in the pregnancy, obviously.

So this is where cancers are very, very different. So I think taking the approach of what would you do if the patient were not pregnant? And what is the best treatment for that particular patient with that particular kind of cancer? And then applying the pregnancy and where the patient is in that pregnancy in terms of the trimester of the pregnancy, and what is safe and what is unsafe from the options that you would give her if she were not pregnant. And then if the patient is choosing to keep the pregnancy, which in my practice, many people come and they come to me because they want to hold onto their pregnancy and want to figure out how to make it work, coming up with a regimen that tries to give them kind of the best bang for the buck, the best possible breast cancer therapy with the least harm, when possible, to the fetus. It is a bit of a balance, right? And then we cannot always give people the best approach. And sometimes it comes down to making a decision to give up something that may improve their survival so as not to harm the fetus. And sometimes it goes the opposite direction where a patient will say, "Oh, that is going to improve my survival by 5% and you can't give it to me now? I am going to choose to terminate." Even though that is obviously a very, very difficult and challenging decision to make in this setting because they want to optimize their survival and ideally live on to potentially have another pregnancy in the future if that is something that is of interest to her. So these are really, really hard conversations as you can imagine, but that is kind of where we go.

Dr. Alison Loren: Yeah, and I think this is where the need for more research and understanding is really key because sometimes questions come up. I guess I am thinking about like HER2-directed agents, which we know are contraindicated in pregnancy. But what about sequencing? Does it matter when you get it? Can you get it later? I think that is something that we don't really fully understand. And similarly, again, this is obviously like a breast cancer and blood cancer focused discussion because that is what we do, but thinking about managing blood cancers, certainly with acute lymphoblastic leukemia, there is actually a lot of options now that, you know, you could potentially use to temporize or sort of get somebody through a pregnancy relatively safely. I am focusing on the word "relatively" because we do not know what the long-term impact might be of potentially not optimal therapy in the long run. And then thinking about other things like timing of a bone marrow transplant relative to either delivery or termination. I mean, again, we really do not know what are the right sets of sort of timing considerations for those. So there are just a lot of unknowns. And I think trying to be sort of self-aware and humble and honest about those unknowns so that the patient can engage in the conversation in a way that is meaningful to her and make the decisions that make the most sense for her. I think the most important thing is to make sure that the patient feels supported and safe to make those decisions with as little regret as possible.

Brittany Harvey: Yes, I think it is really important that you mentioned that there is a wide range of cancers here, and that means that care really needs to be individualized for each patient. I will also note, just in this section, that I found really informative while reading through the guideline the list of oncologic agents that may be offered in each individual trimester, whether it is contraindicated or it can be used with caution, or if there is relatively good safety data on it for prioritizing maternal treatment needs and balancing fetal safety at the same time. I think that is, that is really key. And I think readers will really like that section of the guideline to provide concrete information for them and their patients.

Dr. Alison Loren: Thank you. We actually spent a lot of time on that table and just thinking about what it should look like, what the format ought to be, what the language ought to be. Because of course, at the end of the day, everything should be used with caution. So what does that actually mean? And we sort of tried to explicate that a little bit in like the footnotes. We really tried to leverage what we know from clinical experience, from package labels, from mechanism of action to try to be as clear and definitive as we could be without overstating or understating what we know.

Dr. Ann Partridge: Yeah, and I think we are focusing on breast and leukemia because that is what we do. But the truth is much of the data comes from those two areas. Leukemia, not because it is so common, but because you do not really have choices to treat or not treat. And so for decades, they have been treating and saying, "We hope the progeny comes out okay." And for many agents it does. The babies are okay. And so, we have reasonable observational data. And then in breast cancer, there have been actually some prospective registry-type studies where people have been followed and treated when pregnant, and the progeny have been accounted for, and so we have some good experience in that way too. Again, not randomized trials, but at least data that suggests certain agents are safe. And increasingly, because of that, when we have had to treat patients, we have said, "Okay, let us do it on this registry so that we can at least learn from every patient that comes in in this situation." And so, I think we will have more and more data given the growing number of young adults with cancer and the delays in childbearing that are happening around the world, and particularly in Westernized countries. I wish we did not. We wish we did not see this problem, but of course, when we do, we have to make sure that we learn from it and try and get patients enrolled in these registries and any kinds of studies that are available.

Dr. Alison Loren: Yeah, I will just underscore that to say that, you know, there is outcomes of pregnancy and then there is outcomes of pregnancy, right? So there is like, "Okay, the baby was born with 10 fingers and 10 toes, and they passed their Apgar, and they are doing all their developmental processes along the way." But what happens when they are 10 or 15 or 20? Are they maturing normally? Are they cognitively intact? And then, of course, it is really inseparable from what is the impact on a family of having the mom with cancer? And how does that impact childhood development and intellectual development? And so these are really, really important questions that are very difficult to answer given the longitudinal information that you need, but it is a really critical question that, you know, patients ask and we do not know the answer.

Dr. Ann Partridge: Yeah, that actually leads me to one of the important principles in the guideline that is a little bit of a change from when I first started practicing, which is we have learned from the wider neonatology literature, as they have followed up on the children that were born prematurely, that it is actually better not to be premature and to keep the baby in utero as long as it is safe for the fetus and the mother as long as possible, ideally to term rather than delivering early and then giving the chemo after that or separating the chemo from before and after. We used to try and deliver early and then give agents, but now we typically will give agents that are safe to be given at the end of pregnancy, ideally close to term, a couple weeks out, to allow for the ability of count recovery, and you do not want to go into preterm labor with chemotherapy on board, but we used to go much earlier and have an argument with our maternal-fetal medicine doctors. "How early can you get them out?" And they would say, "How long can they stay in?" And increasingly, we have been able to try and compromise to go even later and allow the fetus to go to term because of the neonatal outcomes that in longer term there is a suggestion that the children are developing better in the long run if they are kept in utero for as long as possible.

Dr. Alison Loren: Yeah, that is such a great point. I think that is probably the most important thing for people to take away. For anyone who sort of does this, I mean, no one does this regularly because it is a rare event, although I think it is increasing as I mentioned. But this idea that the third trimester is, most of us know, is primarily a time for growth. Most of the critical development has already occurred, and so administering most chemotherapy agents towards the end of the third trimester seems to be preferable long term than delivering them early. So that is a really big change. I think we used to try to sort of, "Oh, get them to 30 or 32 weeks and then deliver," but we really are trying to get them closer to term, 37 weeks or more, and then coordinating the treatment so that they are not nadiring, as Ann said, at the time of planned delivery.

Brittany Harvey: Yes, and that is a really important point related to evidence-based care and why we have changed that practice.

And so then that actually leads nicely into my next question. But as you both mentioned, this is an important collaboration between oncologists and obstetricians. So the next section of the guideline addresses obstetrical practice. And so beyond what is standard, what additional recommendations are there in obstetrical management for pregnant patients with cancer?

Dr. Alison Loren: That is a great question. So I will say we were really struggling with like how much do we cover? Like this is an oncology guideline. We are not obstetricians. We certainly had great representation from our maternal-fetal medicine colleagues on the panel. But really trying to sort of give useful information without overstepping. And so I think that the main recommendations are to increase the frequency of fetal monitoring, make sure that there is close attention to blood counts in the patient. But I think there is really still a gap in terms of what we know about optimal management of a pregnant person who is receiving therapy and how to handle the pregnancy itself. The delivery should be a usual delivery. Our colleagues did not recommend a planned C-section. They recommended usual care in terms of planning for the delivery. Obviously, if a C-section is indicated, then it should be done, but it should not be planned this way because of the cancer diagnosis. And I guess the other thing that we mentioned in the guideline, although we were reluctant to push it too hard because of access to these specialized services, was evaluating the placenta after birth to ensure that there were no metastases in the placenta itself.

Dr. Ann Partridge: Those are the main things, and judicious and prudent obstetrical care, as I think, you know, is trying to be practiced regularly with MFM. Typically these patients should be followed not by your average OB/GYN, but a maternal-fetal medicine specialist because these patients will have special concerns, especially if they are sick. So oftentimes, especially Alison's patients, are actually sick with leukemia. And so you are monitoring them a lot, whereas, you know, a breast cancer patient typically isn't sick, although they could get sick with their chemotherapy. And so we really want to hand-in-hand manage these patients with our MFM colleagues.

Dr. Alison Loren: I think we also highlighted in the guideline just for the refresher purposes of the oncology community, generally which drugs that would be given in a normal oncology setting are safe to be given to a pregnant person. So we talked a little bit about what kinds of steroids are recommended, antiemetics, DVT prophylaxis, peripartum. These are things that we think about a lot in oncology, but just want to make sure that it sort of intersected appropriately with the care of a pregnant patient.

Brittany Harvey: Definitely. That specialized care is really important for patients who are pregnant and have cancer.

And then the last section of the recommendations addresses psychological and social support. As you both mentioned before, this is a highly emotional time and it can be difficult and challenging to make decisions. So what is recommended for the psychological and social support of pregnant patients with cancer?

Dr. Ann Partridge: Well, as I said, it is really something that needs to be considered at the beginning, through the diagnostic period, all the way into survivorship. Ironically, even though it is a highly fraught, emotional situation, I find that my pregnant patients actually are extraordinarily resilient, and what they are really focused on often is the safety of the fetus, because again, many of the people that come to me, it is a highly wanted pregnancy. They are also focused on their own health, of course, and often you need to bring in social work, sometimes a psychologist, professionals who are there just to help manage their emotions while we are focusing on what do they need medically to be as healthy as possible, both for the again, the mother, the patient, and the fetus.

It is very tricky, and I will say also bringing in sometimes people on the ethics team in the hospital to help, both from the "Are you recommending and giving something that is safe?" That is number one. And then number two, sometimes patients want to be treated with drugs that we do not have any safety data for in pregnancy. What are our obligations? I think most of us would say we would not treat someone if we do not have safety data and there is suspicion for concern. But where is that line in terms of the right thing to do by that patient? And so we are all beholden to our ethics colleagues to help us when we make decisions like that. You know, we all want to do right by the patient, but we have to uphold our oaths and legal obligations. I don't know if you have to add on that because it's very tricky.

Dr. Alison Loren: It is, it is very hard. I mean, I think, you know, there is a lot of emotion, obviously any cancer diagnosis is extremely charged and people are already at sort of a heightened, you know, they are anticipating a new baby and planning around that. And so it is just an extremely disruptive is the smallest word I can think of to describe it. And I think that often there is a co-parent, there might be parents and in-laws and other siblings, and then there is care after delivery. And so it is just a very complex set of dynamics. And having both our ethics colleagues and our psychology and social work colleagues to sort of just pitch in and make sure that the patient is being supported. I think there are sometimes really difficult situations where maybe what the patient wants is different from what the father of the baby wants or what the rest of the family wants. And so that can be really challenging. And you never really know where those landmines are going to pop up. So it is good to have the team on board early and often.

Dr. Ann Partridge: Yeah, I would add to that, the other thing here that I think is really important, like in all of medicine but especially in situations like this, this is where we have to be very careful as professionals not to impose our own ethical, moral, emotional, personal views on the patient and to try to reserve judgment as much as possible. We are their navigator with the most important evidence and information that we can provide in the current situation. And that is where this guideline is extraordinarily helpful, we hope, for clinicians in the years to come. And at the same time, we cannot necessarily impose our own views and what we would do on a patient or what we tell our daughters, sisters, friends, family members. It is very tricky in that way. And so sometimes not just support for the patient, but support for the care team may be warranted in some of these very fraught situations.

Dr. Alison Loren: Yeah, that is such a great point. And I was sort of thinking that too. I mean, it is, of course, the patient is front and center, but these are really difficult situations to navigate. And I will just add also that a lot of times these patients end up in academic centers, which I think is that's where the expertise or even just the experience may be. But the downside of that is that, you know, the teams are constantly changing. You have a new resident, you have a new intern, you have a new attending, a new fellow. And so, you know, the patients may be subjected to lots of different ways of communicating and sometimes those perceived differences can be really challenging. So sort of team huddles to sort of make sure that everybody is reading from the same script and everyone is comfortable with how the information is being presented so that the patient does not feel more confused or more overwhelmed, that they are kind of getting a consistent message from the whole team that, "This is what we know, this is what we are recommending, here are your other choices, and here are the pros and cons of each of these options."

Brittany Harvey: Yes, I think you have both touched on this and that bringing in appropriate experts to support both clinicians and patients and their decision-making and their mental health is really important for this section of the guideline.

We have already discussed this a fair bit throughout our conversation, but in your view, what is the importance of this guideline and how will it impact both clinicians and pregnant patients diagnosed with cancer?

Dr. Ann Partridge: I could start with that. We just talked about experts and having them all around, but the fact is most people do not have the experts all around when they are dealing with this. And I think this is, you know, an expert-based, evidence-based guideline where having this in one's back pocket, whether you are in rural Montana or at a major cancer center on either coast, you will be armed with the latest and the greatest in terms of what we know and what we do not know, and some very helpful algorithms for how to think through the process of dealing with a patient who is diagnosed during pregnancy, whichever type of cancer it is. We could not cover every single specific thing about every cancer, although it is a pretty long guideline and there is a lot of nuance in there. So you might find a lot about specific cancers. And I think that that will be very, very helpful for people who are faced with this situation in the clinics just to frame it out, think through. Sometimes there is no answer that is the perfect answer and then, you know, using this as kind of a scaffolding and phoning a friend who may have more experience to help guide you and guide the patient, most importantly. I think it will be very helpful in that regard.

Dr. Alison Loren: Yeah, I think so too. And I have talked about that we are working on this guideline and the anecdotal feedback has been, "This is so helpful." Like there really has not been, I think, an all-in-one place, diagnostic considerations, radiographic considerations, staging, treatment, all the modalities, surgical, radiation, systemic chemotherapy. We tried to include, when we could, novel agents including targeted agents and monoclonal antibodies and bispecifics and cellular immunotherapies and non-cellular immunotherapies. We really, really tried to cover in 2025 what are people using to treat cancer and to try to give the most balanced view of what we think is is safe or reasonably safe and what we think is either unproven or known to be risky, really to have it be kind of a go-to, like all-in-one, as much information as we have about these really challenging cases. We tried to include, Ann mentioned, you know, specific cancers, and I think when there were specific things to shout out with specific cancers, we really tried to highlight that. Like, "Okay, lots of young patients with cancer have Hodgkin's lymphoma, so what is safe and what is not for that specific case?" Or, "What is safe or what is not when you are thinking about colon cancers?" And we have a shout-out in here about considering checking for DPD deficiencies in patients who are pregnant. And I know it is generally recommended nowadays, but certainly for people who are pregnant, you know, you really want to avoid excess toxicity. So I think just really trying to be attentive to specifics about certain cancers in young patients and what would be valuable for a practicing oncologist and obstetrician to know when you are faced with this situation.

Dr. Ann Partridge: Yeah, and I think the other critical thing that is great about this guideline is it's a starting place. And I anticipate that we will be building on this guideline for many years to come. And remember that when first, I was not around then, but probably three or four decades ago, when chemotherapy was just coming out and patients were coming in pregnant, there was a feeling I am sure that was, "We cannot give this to this person because it is purposefully going to destroy cells. And when you destroy cells in a growing fetus, you are going to destroy or harm that fetus." And yet, people did not have great choices. It was get treated or die, especially with things like leukemia early on. And bold patients along with their oncologist said, "Bring it on." And that is how some of this literature has been born. And so moving forward, there will be either purposeful exposures or inadvertent exposures of some of our therapies where we will learn ultimately. And this is a place where we can update these guidelines. That is the beautiful thing about the ASCO guidelines is that they are constantly being thought about to be updated. And then when there is enough of a change in practice, they will be updated such that they will continue to inform how we do this in the years to come for patients who come in pregnant.

Dr. Allison Loren: Yeah, and I will say I have been doing this long enough now, we were just talking about a different guideline, the fertility guideline earlier today, and over the 20 years that the fertility guidelines have been out, just the amount of research has really skyrocketed. And you can see as you look at each guideline how much we have learned, what we can say, "Yes, this is working," "No, this is not working." Like, it is stuff that we used to say, "Oh, we do not really know," and now we have answers. 

I think I speak for both of us when I say that we are hopeful that this will serve as, as Ann said, as a starting off point and really inspire people to ask the questions and do the research so that we can give better guidance moving forward, really trying to think about, you know, mechanisms and leaning on our colleagues in pharma and in the government who sort of think about safety and efficacy, to sort of make sure that they are contemplating not just non-pregnant patients, but also pregnant patients or as they are thinking about marking the package inserts with safety guidelines around this.

Brittany Harvey: Yes, this is a critically important first guideline on the management of cancer during pregnancy, and we will look forward to continuing to build on that. I think as you mentioned, this guideline is far-reaching and has a lot of recommendations in it. And so both the full text of the guideline and those at-a-glance algorithms, figures, and tables will be really useful for clinicians in their clinic.

Finally, to wrap us up, we have just been discussing this a little bit, but specifically, what are the outstanding questions on the management of pregnant patients with cancer, and where is this further research needed?

Dr. Alison Loren: There are lots and lots and lots of unanswered questions. And I think if you look at the table, most of what we say is, "We are pretty sure this is okay, we are not so sure about this." I am paraphrasing, but we really just are operating in a paucity of what we would normally consider gold-standard evidence. It is hard to imagine, of course, there would ever be, as we mentioned in the beginning, randomized trials. But I think that preclinical data, mechanistic data, trying to think about including as we go through animal data, making sure that we are looking at female animals and pregnant animals so that we can sort of fully understand what the impact may be. And then I think thinking about more localized therapies around sort of radiation, you know, we are now moving into really hyper-focused radiation treatments like protons. Is that better because there is less scatter? Like I think those are real considerations that we just do not know the answer to.

What do you think?

Dr. Ann Partridge: I think so many unanswered questions, and this is a call to action to continue to and increase the documentation of the experiences and outcomes for patients diagnosed during pregnancy.

Dr. Alison Loren: Yeah, and I think the long-term outcomes too are really going to be critical.

Brittany Harvey: Yes, we will look forward to learning about more evidence across the spectrum of care to inform future updates to this guideline.

So I want to thank you both so much for your work to develop this guideline, to review the extensive amounts of literature that you did, and work to create this guideline. And thank you also for your time today, Dr. Loren and Dr. Partridge.

Dr. Alison Loren: Thanks. It was fun.
