Dr. Pedro Barata and Dr. Kathryn Schmitz discuss evidence-based exercise oncology programs, how to incorporate exercise into cancer care and connect the right patient to the right program, and ultimately build a culture of exercise in oncology. TRANSCRIPT Dr. Pedro Barata: Hello, and welcome to By the Book, a podcast series from ASCO that features compelling perspectives from authors and editors of the ASCO Educational Book. I'm Dr. Pedro Barata. I'm a medical oncologist and a clinical trialist at the University Hospital Seidman Cancer Center and an associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I'm also happy to serve as a deputy editor for the ASCO Educational Book. Today, we'll be talking about exercise. We have plenty of evidence that exercise benefits symptoms, improves the quality of life of patients, and actually has been shown to reduce risk of recurrence of cancer but also improve survival. And I think that's increasingly clear as data emerges. Today, I'm delighted to be speaking to Dr. Kathryn Schmitz. She's a leading expert on integrating exercise into cancer care. Dr. Schmitz serves as the deputy director of the University of Pittsburgh Hillman Cancer Center and also a professor of hematology-oncology at University of Pittsburgh Medical School. She's the senior author of a fantastic article in the ASCO Educational Book that's titled "Implementation Science as the Secret Sauce for Integrating Exercise Screening and Triage Pathways in Oncology." She also led a really compelling piece that just got published in JCO titled "If Exercise Were a Pill, We'd All Prescribe It to Patients With Cancer. But It's Not" So I'm thrilled to have Dr. Schmitz joining us today and helping us explore evidence-based exercise oncology programs, how to incorporate exercise into cancer care, and also how to connect the right patient to the right program.  So with that, welcome, Dr. Schmitz. Thank you so much for taking the time to chat with us. Dr. Kathryn Schmitz: Thank you for the opportunity. Dr. Pedro Barata: One of the highlights of ASCO last year and practice changing, in my opinion, data out of The New England [Journal of Medicine] is called the CHALLENGE trial. It did provide high level evidence that a structured, supervised exercise program could improve both disease-free survival and overall survival. This is a study in the GI world, but I think it got a lot of attraction and attention beyond the GI world, across solid tumors, really. Could you give us a little brief recap of that trial and what have you seen as being the impact in practices around oncology? Dr. Kathryn Schmitz: So, CHALLENGE was very exciting. Prior to CHALLENGE, there were any number of observational studies that indicated that there was a relationship between being more physically active and reduced recurrence and improved overall survival for colon cancer in particular. You know, notably, in 2006, Jeff Meyerhardt published two papers in the same journal, of the same issue of JCO, showing very, very similar data from two very large studies. And those were studies number five and six in this area. You know, there's a lot of evidence observationally, but we don't generally change clinical practice on the basis of observational data. So, we were all waiting very impatiently for the results of the CHALLENGE trial. And it was very exciting to be in the front row when the results were reported out and to be part of the group with a standing ovation for the authors when it was presented. To summarize, 889 colon cancer patients, stage II and III, were randomized into either a structured exercise program or a health education control comparison group and followed for an average of 7.9 years. And the structured exercise group had a 27% reduced risk of recurrence and a 38% improvement in overall survival. One of the things that's really notable about this is that what we typically expect is that when we go from the observational literature to the clinical trial literature, that we expect effects to go down. We expect to see a larger effect in the observational than in the RCT land, and that did not happen here. We actually see an effect that matches what we've seen in observational literature, which is really, really exciting.  And, you know, one of the reasons why this has been so exciting across not just GI but other cancers is the notable finding of a reduced risk of second primaries. So, they only observed two breast cancer second primaries in the treatment group and 12 in the comparison group. And overall, they reduced the second primaries occurrence, hazard ratio was 0.5, a 50% reduction of second primaries, which is just remarkable. It really got everybody very, very excited. And now the big question, of course, is, all right, how do I do this? How do I make this happen?  The thing to note is that what they did in CHALLENGE is probably not doable in your clinic tomorrow. It's a heavy intervention. The number of touchpoints from staff is extensive, and the amount of time needed from staff for the coaching and supervised exercise is extensive as well. The criteria for getting people into the program required that people go through a series of blood tests and imaging tests that would just simply not be possible for the average community oncologist. So I'm guessing that you're going to ask me some questions about how we do this. Dr. Pedro Barata: Right. That's a fantastic segue. That's exactly right. Walk us through maybe starting by, what does that mean? Dr. Kathryn Schmitz: The first thing to say is I have to go back to the observational literature. And the observational literature shows really compellingly that we have a strong reduction of breast cancer recurrence and mortality from being more physically active, prostate cancer recurrence and mortality, and colon cancer recurrence and mortality. I find it very difficult to believe in this day and age, in our current environment, if you will, that we are ever going to have the equivalent of CHALLENGE for prostate or for breast cancer. There is an ongoing study in prostate that's led by some Australian researchers, but I just don't think that it's likely that we're going to mount something similar for another tumor site. We have tremendous correlative data that indicates that there are a number of biomarkers and biological pathways through which breast, colon, and prostate cancer would be reduced in recurrence if people were more physically active. And so, there is really, from my thinking, very little to state that it would be just a colon cancer effect. And so this is something we probably can enact in more than just the colon cancer community, overall, which is great news, and it makes it easier for us to be able to enact this type of programming. Dr. Pedro Barata: One of the things that comes up perhaps often is, if I were the leader of the cancer center and were to incentivize the different care teams to implement an exercise program at each level: GI team, GU, breast, thoracic, etc. How do we do that? Dr. Kathryn Schmitz: So, I want to give you an analogy. You're a medical oncologist, and you prescribe your patients chemotherapy. Now, just imagine, if you will, what would happen and how likely it would be for your patients to get chemotherapy if there was no chemoinfusion suite. If the chemoinfusion suite disappeared tomorrow and you were to tell your patients, "Go get some chemotherapy," what proportion of those patients do you think would go find all of the equipment necessary and all of the drugs necessary and understand how to dose the chemotherapy for themselves and get that all done? Very few people would do it. So with exercise, why would we be surprised then that our patients don't actually do a whole lot if we just simply tell them to go get some exercise? Exercise is a medicine. It is effective like a medicine. We've shown this through the CHALLENGE trial and many other correlative studies and an ocean of observational data as well. So the question is, how do we build the infrastructure that is necessary in order for your patients to do this? So the very first thing that has to happen is that somebody has to tell the patient to exercise. We currently do not have a culture of exercise in oncology. We do in heart disease. If you ask the average person on the street, "Is exercise good for your heart?" Anybody with an eighth-grade education is going to say, "Yes, of course," because the American Heart Association has done an amazing job telling everybody that exercise is good for your heart. But what has ASCO done, frankly? Can I be that bold? What has ASCO done to tell patients that they should be exercising during and after their cancer treatment? I'm not sure that I know more than a guideline. There is a guideline, and that's great. And the guideline is very helpful, but I'm not sure that patients know that there's a guideline. In fact, I can tell you that patients don't know that there is a guideline. So, you know, making sure that there's a paradigm shift in the country that says exercise is good for patients during and after their cancer treatment is the first step. The second step is getting a medical professional to say something to the patient about the exercise. And I'm very careful with the two words that I just chose: medical professional. I do understand medical oncologists are very busy. I understand that there's a whole lot to say in that 15 minutes when you're with the patient. And so maybe it isn't the medical oncologist. Ideally, it would be, but I get it that there's limited time. So it could be a nurse practitioner, it could be a nurse, there could be a social worker, it could be somebody else on the team that says, "Hey, you know, we want you to do an exercise program. We want to connect you to an exercise program." And then there's what is the program itself? You know, I'm very interested in this happening across the entire country. And so I've been working with the leadership of the Commission on Cancer on the question of, well, how would you do this in community oncology? You know, it's not enough to do it in academic medicine, but how do you do this in community oncology? And you can't expect that every community hospital is going to build a gym for their cancer patients. That is just not reasonable to do. So, we start to try to figure out some phone counseling. Could we give people Fitbits and follow them? Could we use technology to help us? Are there telehealth opportunities for us to do? Are there apps that have been built? In fact, there is a [free] app called Cancer Exercise that's on, you know, all of the platforms and available to patients. So there are programs. I've developed a directory of over 2,000 programs that exist across the country for exercise oncology that patients can find, medical oncologists can find.  So there are a lot of people trying to figure out how best to get the information to medical oncologists and other medical professionals so that they can have an 'easy button' to be able to connect their patients to existing programming so that you don't feel like you have to build a whole new program. Dr. Pedro Barata: If I don't have the resources around me, what would be your advice for the care team or for the providers that might not have that available at their site? Where do they start? Who do they reach out to? Who should they be looking at to get more information on how to set it up? Dr. Kathryn Schmitz: I lead an international consortium called Moving Through Cancer. You can find us at movingthroughcancer.org. That's where you'll find the map of all of the programs across the country and the directory. We actually have a triage tool that sits at the front of the directory that allows people to discern what type of exercise they're safe to do. We do recognize that, you know, the 80-year-old that fell last week doesn't need the same program as the 35-year-old that was playing pickleball the day before diagnosis. So, you know, there are different kinds of programs for people at different levels of acuity. We're happy to be helpful to folks to help them set up programs.  But the number one thing is to really be very aware of the power of saying something about doing exercise, just simply the power of saying, "I want you to be moving." Because frankly, I don't think anybody listening to this would disagree, no one benefits from sitting on the couch all day, no one. No one, no one. It doesn't matter how acute their medical issues are. We get people out of bed. We try to move people even when they're in the hospital. So I think saying something is huge. And then, if you can, applying a triage tool, if you can get something embedded within your clinical flow so that you can understand who it is that needs to go to physical therapy as opposed to who's ready for an exercise program. Those are the two things. So triage and referral is kind of step one. And if you can get that done, the rest will fall into place. Dr. Pedro Barata: This is really powerful message, where one, awareness of the care teams. Number two, bring it up to the patient. And then working on the referral, triage and referral process. That's fantastic. Another aspect that comes up quite a bit is like, "Look, this is great, but we have a system that relies on payers to make things happen, or at least to get them approved." And that can be very different or heterogeneous. The coverage can be different. Sometimes already going through a system programs for interventions, therapeutic interventions, let alone probably the insurance is not going to cover that. Is that true? Is it not true? How do you walk through the different insurance supports, perhaps, depending on where you're practicing? Dr. Kathryn Schmitz: You've just hit on the hot button. I've been working on this issue for about nine years now, trying to figure out using efforts to talk to CMS and see if we can get third party payer coverage going. We were making good progress there, and there was a change of administration and a new focus on "Make America Healthy Again," the MAHA movement. And, you know, CMS is really no longer interested in one-off national coverage determination. They instead, they want to know, "How do we make exercise happen for every American over 65?" And my question is, "Well, wait a minute, cancer patients are not just older patients. There's a lot going on there. They need something special." So I've been working on that. It's been working with accrediting bodies for policy with a little p. Very proud of the work that I've done in collaboration with the National Accreditation Program for Breast Centers, trying to get standards to get exercise referrals for breast patients. And I'm currently holding my breath to see whether the CoC is going to try to make some forward motion in this area as well, crossing all period appendages, waiting for news there. So it's not paid for unless it's done by a physical therapist. And, you know, there's published evidence and I have plenty of evidence from UPMC as well, that people don't really want to go to the physical therapist for this. I'm not saying physical therapists aren't great. Physical therapists are great, and there are people who really need to go to physical therapy, and we try hard to get those patients connected. But for the patients that are ready for something more than physical therapy, we really have an uphill battle to try to figure out what insurers are willing to pay for and what the return on investment is.  One of the challenges with the return on investment is that the timeline, time course for return on investment for American insurers is about one year. And I'll remind you that the time course for return on investment for CHALLENGE was 7.9 years. So we have a mismatch there. So we're trying to figure out if we can produce the evidence to show that there is an improvement in unplanned health care utilization. We have documented that for breast cancer. We're working on it for other cancers. If we can document that it is worthwhile to the insurer to pay for these programs, then I believe that they will pay for them. You know, my conversations are very positive with UPMC, which is a very large insurer and a large health plan. We're slowly working our way towards the middle, where there's a program that they can pay for and a program that is efficacious. That's the puzzle we're trying to solve for right now. Dr. Pedro Barata: This has been wonderful and super helpful. Before we wrap it up, is there anything else you would like to share with our listeners? Dr. Kathryn Schmitz: I want to make sure that your audience is aware that there are a variety of ways that exercise oncology is practiced. The program that most oncologists will be familiar with is LIVESTRONG, which is a program at the YMCA. It's a free program. At one point, there were over 800 locations across the U.S. They have contracted since COVID, probably because of COVID. So they still do exist but imagine, if you will, telling your patients that chemo is only available Tuesdays and Thursdays at 7:00 p.m. It would be difficult for patients to get there and get the chemotherapy. The same thing is true for the LIVESTRONG program. It's a fantastic, fantastic program for people who are able to get there, but that's one option. Another option for patients is there are a variety of online opportunities. I'll call out 2Unstoppable for women's cancers. It's literally the number 2Unstoppable.org. It's a free program available to women with cancer to have live, small group training programs. And they're based in Virginia, but they have programs all over the country. And then finally, I just want to overemphasize the app, the Cancer Exercise app. It's literally called Cancer Exercise in the app store. And that is a super duper easy button, very comprehensive, developed by a nurse scientist, Anna Schwartz. And then there are a variety of books. I wrote a book called Moving Through Cancer. There's a new book out [MyExerciseMedicine for Cancer] by Dr. Rob Newton as well, who's an Australian author. And there are certifications for exercise professionals that folks can look into as well through the American College of Sports Medicine. Dr. Pedro Barata: Dr. Schmitz, this is fantastic. Thank you for sharing those great insights with us. Super, super helpful. Thank you for taking the time. Dr. Kathryn Schmitz: Thank you so much. Dr. Pedro Barata: Thank you to our listeners for your time today. Remember, you'll find links to Dr. Schmitz's fantastic Educational Book as well as the JCO articles in the transcript of this episode. I'll invite all of you to go and read. And we'll also include a link to Dr. Schmitz's book titled Moving Through Cancer: An Exercise and Strength Program for the Fight of Your Life, which empowers patients and caregivers in simple five steps.  So with that, please join us again next month on By the Book for more insights on key advances and innovations that are shaping modern oncology.

Dr. Pedro Barata and Dr. Ugwuji Maduekwe discuss the evolving treatment landscape in gastroesophageal junction and gastric cancers, including the emergence of organ preservation as a selective therapeutic goal, as well as strategies to mitigate disparities in care. Dr. Maduekwe is the senior author of the article, "Organ Preservation for Gastroesophageal Junction and Gastric Cancers: Ready for Primetime?" in the 2026 ASCO Educational Book. TRANSCRIPT Dr. Pedro Barata: Hello, and welcome to By the Book, a podcast series from ASCO that features compelling perspectives from authors and editors of the ASCO Educational Book. I'm Dr. Pedro Barata. I'm a medical oncologist at University Hospitals Seidman Cancer Center and an associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I'm also the deputy editor of the ASCO Educational Book. Gastric and gastroesophageal cancers are the fifth most common cancer worldwide and the fourth leading cause of cancer-related mortality. Over the last decade, the treatment landscape has evolved tremendously, and today, organ preservation is emerging as an attainable but still selective therapeutic goal. Today, I'm delighted to be speaking with Dr. Ugwuji Maduekwe, an associate professor of surgery and the director of regional therapies in the Division of Surgical Oncology at the Medical College of Wisconsin. Dr. Maduekwe is also the last author of a fantastic paper in the 2026 ASCO Educational Book titled "Organ Preservation for Gastroesophageal Junction and Gastric Cancers: Ready for Prime Time?" We explore these questions in our conversations today.  Our full disclosures are available in the transcript of this episode as well. Welcome. Thank you for joining us today. Dr. Ugwuji Maduekwe: Thank you, Dr. Barata. I'm really, really glad to be here. Dr. Pedro Barata: There's been a lot of progress in the treatment of gastric and gastroesophageal cancers. But before we actually dive into some of the key take-home points from your paper, can you just walk us through how systemic therapy has emerged and actually allowed you to start thinking about a curative framework and really informing surgery decision-making? Dr. Ugwuji Maduekwe: Great, thank you. I'm really excited to be here and I love this topic because, I'm terrified to think of how long ago it was, but I remember in medical school, one of my formative experiences and why I got so interested in oncology was when the very first trials about imatinib were coming through, right? Looking at the effect, I remember so vividly having a lecture as a first-year or second-year medical student, and the professor saying, "This data about this particular kind of cancer is no longer accurate. They don't need bone marrow transplants anymore, they can just take a pill." And that just sounded insane. And we don't have that yet for GI malignancies. But part of what is the promise of precision oncology has always been to me that framework. That framework we have for people with CML who don't have a bone marrow transplant, they take a pill. For people with GIST. And so when we talk about gastric cancers and gastroesophageal cancers, I think the short answer is that systemic therapy has forced surgeons to rethink what "necessary" really means, right? We have the old age saying, "a chance to cut is a chance to cure." And when I started out, the conversation was simple. We diagnose the cancer, we take it out. Surgery's the default. But what's changed really over the last decade and really over the last five years is that systemic therapy has gotten good enough to do what is probably real curative work before we ever enter the operating room. So now when you see a patient whose tumor has essentially melted away on restaging, the question has to shift, right? It's no longer just, "Can I take this out?" It's "Has the biology already done the heavy lifting? Have we already given them systemic therapy, and can we prove it safely so that maybe we don't have to do what is a relatively morbid procedure?" And that shift is what has opened the door to organ preservation. Surgery doesn't disappear, but it becomes more discretionary. Necessary for the patients who need it, and within systems that can allow us to make sure that we're giving it to the right patients. Dr. Pedro Barata: Right, no, that makes total sense. And going back to the outcomes that you get with these systemic therapies, I mean, big efforts to find effective regimens or cocktails of therapies that allow us to go to what we call "complete response," right? Pathologic complete response, or clinical complete response, or even molecular complete response. We're having these conversations across different tumors, hematologic malignancies as well as solid tumors, right? I certainly have those conversations in the GU arena as well. So, when we think of pathologic CRs for GI malignancies, right? If I were to summarize the data, and please correct me if I'm wrong, because I'm not an expert in this area, the traditional perioperative chemo gives you pCRs, pathologic complete response, in the single digits. But then when you start getting smarter at identifying biologically distinct tumors such as microsatellite instability, for instance, now you start talking about pCRs over 50%. In other words, half of the patients' cancer goes away, it melts down by offering, in this case, immunotherapy as a backbone of that neoadjuvant. But first of all, this shift, right, from going from these traditional, "not smart" chemotherapy approaches to kind of biologically-driven approaches, and how important is pCR in the context of "Do I really need surgery afterwards?" Dr. Ugwuji Maduekwe: That's really the crux of the entire conversation, right? We can't proceed and we wouldn't be able to have the conversation about whether organ preservation is even plausible if we hadn't been seeing these rates of pathologic complete response. If there's no viable tumor left at resection, did surgery add something? Are we sure? The challenge before this was how frequently that happened. And then the next one is, as you've already raised, "Can we figure that out without operating?" In the traditional perioperative chemo era, pathologic complete response was relatively rare, like maybe one in twenty patients. When we go to more modern regimens like FLOT, it got closer to one in six. When you add immunotherapy in recent trials like MATTERHORN, it's nearly triple that rate. And it's worth noting here, I'm a health services-health disparities researcher, so we'll just pause here and note that those all sound great, but these landmark trials have significant representation gaps that limit and should inform how confidently we generalize these findings. But back to what you just said, right, the real inflection point is MSI-high disease where, with neoadjuvant dual-checkpoint blockade, trials like NEONIPIGAS and INFINITY show pCR rates that are approaching 50% to 60%. That's not incremental progress, that's a whole new different biological reality. What does that mean? If we're saying that 50% to 60% of the people we take to the OR at the time of surgery will end up having no viable tumor, man, did we need to do a really big surgery? But the problem right now is the gold standard, I think we would mostly agree, the gold standard is pathologic complete response, and we only know that after surgery. I currently tell my patients, right, because I don't want them to be like, "Wait, we did this whole thing." I'm like, "We're going to do this surgery, and my hope is that we're going to do the surgery and there will be no cancer left in your stomach after we take out your stomach." And they're like, "But we took out my stomach and you're saying it's a good thing that there's no cancer." And yes, right now that is true because it's a measure of the efficacy of their systemic therapy. It's a measure of the biology of the disease. But should we be acting on this non-operatively? To do that, we have to find a surrogate. And the surrogate that we have to figure out is complete clinical response. And that's where we have issues with the stomach. In esophageal cancer, the preSANO protocol, which we'll talk about a little bit, validated a structured clinical response evaluation. People got really high-quality endoscopies with bite-on biopsies. They got endoscopic ultrasounds. They got fine-needle aspirations and PET-CT, and adding all of those things together, the miss rate for substantial residual disease was about 10% to 15%. That's a number we can work with. In the stomach, it's a lot more difficult anatomically just given the shape of people's stomachs. There's fibrosis, there's ulceration. A fair number of stomach and GEJ cancers have diffuse histology which makes it difficult to localize and they also have submucosal spread. Those all conceal residual disease. I had a recent case where I scoped the patient during the case, and this person had had a 4 cm ulcer prior to surgery, and I scoped and there was nothing visible. And I was elated. And on the final pathology they had a 7 cm tumor still in place. It was just all submucosal. That's the problem. I'm not a gastroenterologist, but I would have said this was a great clinical response, but because it's gastric, there was a fair amount of submucosal disease that was still there. And our imaging loses accuracy after treatment. So the gap between what looks clean clinically and what's actually there pathologically remains very wide. So I think that's why we're trying to figure it out and make it cleaner. And outside of biomarker-selected settings like MSI-high disease, in general, I'm going to skip to the end and our upshot for the paper, which is that organ preservation, I would say for gastric cancer particularly, should remain investigational. I think we're at the point where the biology is increasingly favorable, but our means of measurement is not there yet. Dr. Pedro Barata: Gotcha. So, this is a perfect segue because you did mention the SANO, just to spell it out, "Surgery As Needed for Oesophageal" trial, so SANO, perfect, I love the abbreviation. It's really catchy. It's fantastic, it's actually a well-put-together perspective effort or program applying to patients. And can you tell us how was that put together and how does that work out for patients? Dr. Ugwuji Maduekwe: Yeah, I think for those of us in the GI space, we have SANO and then we also have the OPRA for rectum. SANO for the upper GI is what takes organ preservation from theory to something that's clinically credible. The trial asked a very simple question. If a patient with a GEJ adenocarcinoma or esophageal adenocarcinoma achieved what was felt to be a clinical complete response after chemoradiation, would they actually benefit from immediate surgery? And the question was, "Can you safely observe?" And the answer was 'yes'. You could safely observe, but only if you do it right. And what does that mean? At two years, survival with active surveillance was not inferior to those who received an immediate esophagectomy. And those patients had a better early quality of life. Makes sense, right? Your quality of life with an esophagectomy versus not is going to be different. That matters a lot when you consider what the long-term metabolic and functional consequences of an esophagectomy are. The weight loss, nutritional deficiencies that can persist for years. But SANO worked because it was very, very disciplined and not permissive. You mentioned rigor. They were very elegant in their approach and there was a fair amount of rigor. So there were two main principles. The first was that surveillance was front-loaded and intentional. So they had endoscopies with biopsies and imaging every three to four months in the first year and then they progressively spaced it out with explicit criteria for what constituted failure. And then salvage surgery was pre-planned. So, the return-to-surgery pathway was already rehearsed ahead of time. If disease reappeared, take the patient to the OR within weeks. Not sit, figure out what that means, think about it a little bit and debate next steps. They were very clear about what the plan was going to be. So they've given us this blueprint for, like, watching people safely. I think what's remarkable is that if you don't do that, if you don't have that infrastructure, then organ preservation isn't really careful. It's really hopeful. And that's what I really liked about the SANO trial, aside from, I agree, the name is pretty cool. Dr. Pedro Barata: Yeah, no, that's a fantastic point. And that description is spot on. I am thinking as we go through this, where can this be adopted, right? Because, not surprisingly, patients are telling you they're doing a lot better, right, when you don't get the esophagus out or the stomach out. I mean, that makes total sense. So the question is, you know, how do you see those issues related to the logistics, right? Getting the multi-disciplinary team, getting the different assessments of CR. I guess PETs, a lot of people are getting access to imaging these days. How close do you think this is, this kind of program, to be implemented? And maybe I would assume it might need to be validated in different settings, right, including the community. How close or how far do you think you see that being applied out there versus continuing to be a niche program, watch and wait program, in dedicated academic centers? Dr. Ugwuji Maduekwe: I love this question. So I said at the top of this, I'm a health equity/health disparities researcher, and this is where I worry the most. I love the science of this. I'm really excited about the science. I'm very optimistic. I don't think this is a question of "if," I think it's a question of "when." We are going to get to a point where these conversations will be very, very reasonable and will be options. One of the things I worry about is: who is it going to be an option for? Organ preservation is not just a treatment choice, and I think what you're pointing out very rightly is it's a systems-level intervention. Look at what we just said for SANO. Someone needs to be able to do advanced endoscopy, get the patients back. We have to have the time and space to come back every three to four months. We have to do molecular testing. There needs to be multi-disciplinary review. There needs to be intensive surveillance, and you need to have rapid access to salvage surgery. Where is that infrastructure? In this country, it's mostly in academic centers. I think about the panel we had at ASCO GI, which was fantastic. And as we were having the conversation, you know, we set it up as a debate. So folks were debating either pro-surveillance or pro-surgery. But both groups, both people, were presenting outcomes based on their centers. And it was folks who were fantastic. Dr. Molena, for example, from Memorial Sloan Kettering was talking about their outcomes in esophagectomies [during our session at GI26], but they do hundreds of these cases there per year. What's the reality in this country? 70% to 80% to 90%, depending on which data you look at, of the gastrectomies in the United States occur at low-volume hospitals. Most of the patients at those hospitals are disproportionately uninsured or on government insurance, have lower income and from racial and ethnic minority groups. So if we diffuse organ preservations without the system to support it, we're going to create a two-tiered system of care where whether you have the ability to preserve your organs, to preserve bodily integrity, depends on where you live and where you're treated. The other piece of this is the biomarker testing gap. One of the things that, as you pointed out at the beginning, that's really exciting is for MSI-high tumors. Those are the patients that are most likely to benefit from immunotherapy-based organ preservation. But here's the problem. If the patient isn't tested at time of initial diagnosis before they ever see me as a surgeon, the door to organ preservation is closed before it's ever open. And testing access remains very inconsistent across academic networks. And then there's the financial toxicity piece where, for gastrectomy, pancreatectomy, I do peritoneal malignancies, more than half of those patients experience significant financial toxicity related to their cancer treatment. We're now proposing adding at least two years, that's the preliminary information, right? It's probably going to be longer. At least a couple of years of surveillance visits, repeated endoscopies, immunotherapy costs. How are we going to support patients through that? We're going to have to think about setting up navigation support, geographic solutions, what financial counseling looks like. My patient for clinic yesterday was driving to see me, and they were talking about how they were sliding because it was snowing. And they were sliding for the entire three-hour drive down here. Are we going to tell people like that that they need to drive down to, right, I work at a high-volume center, they're going to need to come here every three months, come rain or snow, to get scoped as opposed to the one-time having a surgery and not needing to have the scopes as frequently? My concern, like I said, I'm an optimist, I think it is going to work. I think we're going to figure out how to make it work. I'm worried about whether when we deploy it, we widen the already existing disparities. Dr. Pedro Barata: Gotcha, and that's a fantastic summary. And as I'm thinking also of what we've been talking in other solid tumors, which one of the following do you think is going to evolve first? So we are starting to use more MRD-based assays, which are based on blood test, whether it's a tumor-informed ctDNA or non-informed. We are also trying to get around or trying to get more information response to systemic therapies out of RNA-seq through gene expression signatures, or development of novel therapeutics which also can help you there. Which one of these areas you think you're going to help this SANO-like approach move forward, or you actually think it's actually all of the above, which makes it even more complicated perhaps? Dr. Ugwuji Maduekwe: I think it's going to be all of the above for a couple of reasons. I would say if I had to pick just one right now, I think ctDNA is probably the most promising and potentially the missing piece that can help us close the gap between clinical and pathologic response. If you achieve clinical complete response and your ctDNA is negative, so you have clinical and molecular evidence of clearance, maybe that's a low-risk patient for surveillance. If you have clinical complete response but your ctDNA remains positive, I would say you have occult molecular disease and we probably need intensified therapy, closer monitoring, not observation. I think the INFINITY trial is already incorporating ctDNA into its algorithm, so we'll know. I don't think we're at the point where it alone can drive surgical decisions. I think it's going to be a good complement to clinical response evaluation, not a replacement. The issue of where I think it's probably going to be multi-dimensional is the evidence base: who are we testing? Like, what is the diversity, what is the ancestral diversity of these databases that we're using for all of these tests? How do we know that ctDNA levels and RNA-seq expression arrays are the same across different ancestral groups, across different disease types? So I think it's probably going to be an amalgam and we're going to have to figure out some sort of algorithm to help us define it based on the patient characteristics. Like, I think it's probably different, some of this stuff is going to be a little bit different depending on where in the stomach the cancer is. And it's going to be a little bit more difficult to figure out if you have a complete clinical response in the antrum and closer to the pylorus, for example. That might be a little bit more difficult. So maybe the threshold for defining what a clinical complete response needs to be is higher because the therapeutic approach there is not quite as onerous as for something at the GE-junction. Dr. Pedro Barata: Wonderful. And I'm sure AI, whether it's digitization of the pathology from the biopsies and putting all this together, probably might play a role as well in the future.  Dr. Maduekwe, it's been fantastic. Thank you so much for sharing your insights with us and also congrats again for the really well-done review published.  For our listeners, thank you for staying with us. Thank you for your time.

Dr. Hope Rugo and Dr. Vivek Subbiah discuss innovative trial designs to enable robust studies for smaller patient populations, as well as the promise of precision medicine, novel therapeutic approaches, and global partnerships to advance rare cancer research and improve patient outcomes. TRANSCRIPT  Dr. Hope Rugo: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I am your host, Dr. Hope Rugo. I am the director of the Women's Cancers Program and division chief of breast medical oncology at the City of Hope Cancer Center [in Los Angeles]. The field of rare cancer research is rapidly transforming thanks to progress in clinical trials and treatment strategies, as well as improvements in precision medicine and next-generation sequencing that enable biomarker identification. According to the National Cancer Institute, rare cancers occur in fewer than 150 cases per million each year, but collectively, they represent a significant portion of all cancer diagnoses. And we struggle with the appropriate treatment for these rare cancers in clinical practice. Today, I am delighted to be joined by Dr. Vivek Subbiah, a medical oncologist and the chief of early-phase drug development at the Sarah Cannon Research Institute in Nashville, Tennessee. Dr. Subbiah is the lead author of a paper in the ASCO Educational Book titled "Designing Clinical Trials for Patients with Rare Cancers: Connecting the Zebras," a great title for this topic. He will be telling us about innovative trial designs to enable robust studies for small patient populations, the promise of precision medicine, and novel therapeutic approaches to improve outcomes, and how we can leverage AI now to enroll more patients with rare cancers in clinical trials. Our full disclosures are available in the transcript of this episode.  Dr. Subbiah, it is great to have you on the podcast today. Thanks so much for being here. Dr. Vivek Subbiah: Thank you so much, Dr. Rugo, and it is an honor and pleasure being here. And thank you for doing this podcast for rare cancers. Dr. Hope Rugo: Absolutely. We are excited to talk to you. And congratulations on this fantastic paper. It is such a great resource for our community to better understand what is new in the field of rare cancer research. Of course, rare cancers are complex and multifaceted diseases. And this is a huge challenge for clinical oncologists. You know, our clinics, of course, cannot be designed as we are being very uni-cancer focused to just be for one cancer that is very rare. So, oncologists have to be a jack of all trades in this area. Your paper notes that there are approximately 200 distinct types of rare and ultra-rare cancers. And, by definition, all pediatric cancers are rare cancers. Of course, clinical trials are essential for developing new treatment strategies and improving patient outcomes, and in your paper, you highlight some unique challenges in conducting trials in this rare cancer space. Can you tell us about the challenges and how really innovative trial designs, I think a key issue, are being tailored to the specific needs of patients with rare cancer and, importantly, for these trials? Dr. Vivek Subbiah: Rare cancers present a perfect storm of challenges. First, the patient populations are very small, which makes it really hard to recruit enough participants for traditional type trials. Second, these patients are often geographically dispersed across multiple cities, across multiple states, across multiple countries, across multiple zip codes. So, logistics become complicated. Third, there is often limited awareness among clinicians, which delays referrals and diagnosis. Add to that regulatory hurdles, funding constraints, and you can see why rare cancer trials are so tough to execute. To overcome these barriers, we are seeing some really creative novel trial designs. And there are four different types of trial designs that are helping with enrolling patients with rare cancers. The first one is the basket trial. So let us talk about what basket studies are. Basket studies group patients based on shared genetic biomarkers or shared genetic mutations rather than tumor type. So instead of running separate 20 to 30 to 40 trials, you can study one therapy across multiple cancers. The second type of trial is the umbrella trial. The umbrella trials flip that concept of basket studies. They focus on one cancer type but test multiple targeted therapies within it. The third category of innovative trials are the platform studies. Platform trials are another exciting innovation. They allow new treatment arms to be added or removed as the data matures and as the data evolves, making trials more adaptive and efficient. The final category are decentralized tools in traditional trials, which are helping patients participate closer to where they are so that they can sleep in their own bed, which is, I think, a game changer for accessibility.  These designs maximize efficiency and feasibility for rare cancer research and rare cancer clinical trials. Dr. Hope Rugo: I love the idea of the platform trials that are decentralized. And I know that there is a trial being worked on with ARPA-H (Advanced Research Projects Agency for Health) funding in triple-negative breast cancer as well as in lung cancer, I think, and others with this idea of a platform trial. But it is challenged, I think, by precision medicine and next-generation sequencing where some patients do not have targetable markers, or there isn't a drug to target the marker. I think those are almost the same thing. We have really seen that these precision medicine ideas and NGS have moved the needle in helping to identify genetic alterations. This helps us to be more personalized. It actually helps with platform studies to customize trial enrollment. And we hope that this will result in better outcomes. It also allows us, I think, to study drugs even in the early stage setting more effectively. How can these advances be best applied to the future of rare cancers, as well as the challenges of not finding a marker or not having a drug? Dr. Vivek Subbiah: Thank you so much for that question. I think precision medicine and next-gen sequencing, or NGS, are truly the backbone of modern precision oncology. They have transformed how we think about cancer treatment. Instead of treating based on where the tumor originated or where the tumor started, we now look at the genetic blueprint of cancer. The NGS or next-gen sequencing allows us to sequence millions of DNA fragments quickly. Twenty, 30 years ago, they said we cannot sequence a human genome. Then it took almost a decade to sequence the first human genome. Right now, we have academic centers and commercial sequencing companies that are really democratizing NGS across all sites, not just in academic centers, across all the community sites, so that NGS is now accessible. This means that we can identify these actionable alterations like picking needles in haystacks, like NTRK fusions, RET fusions, or BRAF V600E alterations, high tumor mutational burden. This might occur across not one tumor type, across several different tumor types. So for rare cancers, this is critical because some of these mutations often define the best treatment option. Here is why this matters. Personalized therapy, right? Instead of a one-size-fits-all approach, we can tailor treatment to the patient's unique molecular profile. For trial enrollment, this can definitely help because patients can join biomarker-driven trials even if their cancer type is rare or ultra-rare. NGS technology has also helped us in designing rational studies. Many times monotherapy does not work in these cancers. So we are thinking about rational combination strategies. So NGS technology is helping us. Looking ahead, I see NGS becoming routine in clinical practice, not just at major niche academic centers, but everywhere. We will see more tumor-agnostic approvals, more molecular tumor boards guiding treatment decisions in real time. And I think we are seeing an expanded biomarker setup. Previously, we used to have only a few drugs and a handful of mutations. Now with homologous recombination defects, BRCA1/2 mutation, and expanding the HRD and also immunohistochemistry, we are expanding the biomarker portfolio. So again, I personally believe that the future is precision. What I mean by precision is delivering the right drug to the right patient at the right time. And for rare cancers, this isn't just progress. It is survival. And it is maybe the only way that they can have access to these cutting-edge precision medicines. Dr. Hope Rugo: That is so important. You mentioned an important area we will get to in a moment, the tumor-agnostic therapies. But as part of talking about that, do you think that the trials should also include just standard therapies? You know, who do you give an ADC to and when with these rare cancers? Because some of them do not have biomarkers to target and it is so disappointing for patients and providers where you are trying to screen a patient for a trial or a platform trial where you have one arm with this mutation, one arm with that, and they do not qualify because they only have a p53 loss, you know? They just do not have the marker that helps them. But we see this in breast cancer all the time. And it is tough because we don't have good information on the sequencing. So I wonder, you know, just because for some of these rare cancers it is not even clear what to use when with standard treatments. And then that kind of gets into this idea of the tumor-agnostic therapies that you mentioned. There are a lot of new treatments that are being evaluated. We have seen approval of some treatments in the last few years that are tumor-agnostic and based on a biomarker. Is that the best approach as we go forward for rare cancers? And what new treatment options are most exciting to you right now? Dr. Vivek Subbiah: Tumor-agnostic therapies, really close to my heart, are real breakthrough therapies and represent a major paradigm shift in oncology. Traditionally, for the broad listeners here, we are used to thinking about designing clinical trials and therapy like where the cancer originated, breast cancer, kidney cancer, prostate cancer, lung cancer. A tumor-agnostic therapy flips that model. Instead of focusing on the organ, they target the specific genetic alteration or biomarker that drives cancer growth regardless of where the tumor started, regardless of the location of the tumor, regardless of the zip code of the tumor. So why is this so important for rare cancers? Because many rare cancers share molecular features with more common cancers. For instance, NTRK fusion might occur in pediatric sarcoma, a salivary gland tumor, or a thyroid cancer. Historically, each of these would require separate trials, which is nearly impossible, unfeasible to conduct in these ultra-rare cancers like salivary gland cancer or pediatric sarcomas. Tumor-agnostic therapies allow us to treat all those cancers with the same targeted drug if they share that biomarker. Again, we are in 2025. The first tissue-agnostic approval, the historic precedent, was in fact an immunotherapy. Pembrolizumab was approved in 2017, May 2017, as the first immunotherapy to be approved in a tumor-agnostic way for a genomic biomarker, for MSI-High and dMMR cancers. Then came the NTRK inhibitors. So today we have not one, not two, but three different NTRK inhibitors: larotrectinib, entrectinib, and repotrectinib, which show response rates of nearly more than 60 to 75% across a handful of dozens and dozens of cancer types. Then, of course, we have RET inhibitors like selpercatinib, which is approved tissue-agnostic, and pralsetinib, which also shows tissue-agnostic activity across multiple cancers. And more recently, combination therapy with a BRAF and MEK combination, dabrafenib and trametinib, received tumor-agnostic approval for all BRAF V600E tumors with the exception of colorectal cancer. And even recently, you mentioned about antibody drug conjugates. Again, I think we live in an era of antibody drug conjugates. And Enhertu, trastuzumab deruxtecan, which was used first in breast cancer, now it is approved in a histology-agnostic manner for all HER2-positive tumors defined by immunohistochemistry 3+. So again, beyond NGS, now immunohistochemistry for HER2 is also becoming a biomarker. So again, for the broad listeners here, in addition to comprehensive NGS that may allow patients to find treatment options for these rare cancers for NTRK, RET, and BRAF, immunohistochemistry for HER2 positivity is also emerging as a biomarker given that we have a new FDA approval for this. So I would say personally that these therapies are game changers because they open doors for patients who previously had no options. Instead of waiting for years for a trial in their specific cancer type, they can access a treatment based on their molecular profile. I think it is precision medicine at its finest and best. Looking ahead, the third question you asked me is what is exciting going on? I think we will see more of these approvals. My hope is that today, I think we have nine to ten approvals. My hope is that within the next 25 to 50 years, we will have at least 50 to 100 drugs approved in this space based on a biomarker, not based on a location of the tumor type. Drug targeting rare alterations like FGFR2 fusions, FGFR amplifications, ALK fusions, and even complex signatures like high tumor mutational burden. I think we will be seeing hopefully more and more drugs approved. And as sequencing becomes routine, we will identify more patients for these therapies. I think for rare cancers, this is not just innovative approach. This is essential for them to access these novel precision medicines. Dr. Hope Rugo: Yeah, that is such a good point. I do think it is critical. Interestingly in breast cancer, it hasn't been, you know, there is always like two patients in these tumor-agnostic trials, or if that. You know, I think I have seen one NTRK fusion ever. I think that highlights the importance for rare cancers. And you know, I am hoping that that will translate into some new directions for some of our rarer and impossible-to-treat subtypes of breast cancer. It is this kind of research that is really going to make a difference. But what about those people who do not have biomarkers? What if you do not fit into that? Do you think there is a possibility of trying to do treatments for rare cancers in some prospective way that would help with that? You know, it is really a huge challenge. Dr. Vivek Subbiah: Absolutely. I think, you know, you're right, usually many of these rare cancers are driven by specific biomarkers. And again, some of the pediatric salivary gland tumors or pediatric sarcomas like fibrosarcomas, they are pathognomonic with NTRK fusions. And again, given that we have a tumor-agnostic approval, now these patients have access to these therapies. And I do not think that we would have had a trial just for pediatric fibrosarcomas with NTRK fusions. So that is one way. Another way is SWOG, right? The SWOG DART [1609] had this combination dual checkpoint, it was called the DART study dual combination chemotherapy with ipi/nivo. Now here the rare cancer subtype itself becomes a biomarker and they showed activity across multiple rare cancer subtypes. They didn't require a biomarker. As long as it was a rare or ultra-rare cancer, these patients were enrolled into the SWOG DART trial and multiple arms have read out. Angiosarcoma, Kaposi sarcoma, even gestational trophoblastic disease. Again, they have shown responses in these ultra-rare, rare cancers. Sometimes they might be seeing one or two cases a whole year. And I think this SWOG effort, this cooperative group effort, really highlighted the need for such studies without biomarkers as well. Dr. Hope Rugo: That is such a fantastic example of how to try and treat patients in a collaborative way. And in the paper, you also emphasize the need for collaborative research efforts, you know, uniting resource expertise across different ways of doing research. So cooperative groups, advocacy organizations that can really help advance rare cancer research, improve access to new therapies, and I think importantly influence policy changes. I think this already happened with the agnostic approvals. Could you tell us more about that? How can we move forward with this most effectively? Dr. Vivek Subbiah: Personally, I believe that collaboration is absolutely critical and essential for rare cancer research. No single institution, no single individual, or no single state or entity can tackle these challenges alone. The patient populations are small and dispersed. So pooling resources is the only way to run these meaningful trials. Again, it is not like singing, it is like putting a huge, huge, I would say, an opera piece together. It is not a solo, vocal therapy, but rather putting a huge opera piece like Turandot. You know, you mentioned cooperative groups. Cooperative groups, as I mentioned earlier, the SWOG DART program, the ASCO [TAPUR study]. ASCO is doing a phenomenal work of the TAPUR study. Again, this ASCO TAPUR program has enrolled so many patients with rare cancers who otherwise would not have treatment options. NCI-MATCH, the global effort, right? NCI-MATCH and the ComboMATCH are great examples. They bring together hundreds of sites, thousands of clinicians to run large-scale trials that would be impossible for any individual center or institution. These trials have already changed practice. For instance, the DART demonstrated the power of immunotherapy in rare cancers and influenced NCCN guidelines. One of the arms of the NCI-MATCH study from the BRAF V600E arm contributed towards the BRAF V600E tissue-agnostic approval. So, the BRAF V600E tissue-agnostic approval was by a pooled analysis of several studies. The ROAR study, the Rare Oncology Agnostic Research study, the NCI-MATCH dataset of tumor-agnostic cohort, and another pediatric trial, and also evidence from literature and evidence of case reports. And all this pooled analysis contributed to the tissue-agnostic approval of BRAF V600E across multiple rare cancers. There are several patient advocacy organizations which are the real unsung heroes here. Groups like, for instance, we mentioned in the paper, Target Cancer Foundation, don't just raise awareness for rare cancer research, they actively connect patients to trials providing financial, emotional support, and even run their own studies like the TRACK trial. They also influence policy to make access easier. On a global scale, initiatives like DRUP in the Netherlands, the ROME study in Italy, the PCM4EU in Europe are expanding precision medicine across these borders. These collaborations accelerate research, improve trial enrollment, and ensure patients everywhere can have access to these cutting-edge therapies. Again, it is truly a team effort, right? It is a multi-stakeholder approach. Researchers, clinicians, investigators, industry, regulators, academia, patients, patient advocates, and their caregivers all working together. And it takes a village. Dr. Hope Rugo: Absolutely. I mean, what a nice response to that. And I think really exciting and it is great to see your passion about this as well. But it helps all of us, I think, getting discouraged in treating these cancers to understand what is happening moving forward. And I think it is also a fabulous opportunity for our junior colleagues as they rise up in academics to be involved in these international collaborative efforts which are further expanding. One of the things that comes up for clinical trials for patients, and I think it is highlighted with rare cancers because, as you mentioned, people are all over the place, you know, they are so rare. They are all far away. Our patients are always saying to us, "Should I go here for a phase 1 trial?" Can you talk a little bit about how we can overcome these financial and geographic burdens for the patients? You talked about having trials locally, but it is a big financial and just social burden for patients. Dr. Vivek Subbiah: Great point. Financial cost is a major barrier in rare cancer clinical trials. It is a major barrier not just in rare cancer clinical trials, but in clinical trials in general. The economics of rare cancer research are one of the toughest challenges we face. Developing a new drug is already expensive, often billions of dollars. On an average, it takes 2 billion dollars or 2.8 billion dollars according to some data from drug discovery to approval. For rare cancers, the market is tiny, which means the pharmaceutical companies have really little financial incentive to invest. That is why initiatives like the Orphan Drug Act were created to provide tax credits, grants, and market exclusivity to encourage development for rare diseases. Clinical trials themselves are expensive because the small patient populations mean longer recruitment times and higher per-patient costs. Geographic dispersion, as you mentioned, for the patients adds travel, coordination. That is why we need to think out of the box about decentralized trial infrastructure so that we can mitigate some of these expenses. Complex trial designs like basket or platform trials sometimes require sophisticated data systems and regulatory oversight. That is a challenge. And I think some of the pragmatic studies like ASCO TAPUR have overcome those challenges. Advanced technologies like next-gen sequencing and molecular profiling also add significant upfront cost to this. Funding is also limited because rare cancers receive less attention compared to common cancers. Public funding and cooperative group trials help a lot, but I think they cannot cover everything. Patient advocacy organizations sometimes step in to bridge these gaps, but sustainable financing remains a huge challenge. So, the bottom line is without financial incentives and collaborating funding models, many promising therapies for rare cancers would never make it to patients. That is why we need system-wide policy changes, global partnerships, and innovative, effective, seamless trial designs which are so critical so that they can help reduce the cost and make research feasible so that we can deliver the right drug to the right patient at the right time. Dr. Hope Rugo: There is a lot of excitement about the future integration of AI in screening. Just at the San Antonio Breast Cancer meetings, we have a number of different presentations about AI to find markers, even like HER2, and using AI where you would screen and then match patients to clinical trials. Do you have any guidance for the rare cancer community on how to leverage this technology in order to optimize patient enrollment and, I think, identification of the best treatment matches? Dr. Vivek Subbiah: I think artificial intelligence, AI, is a game-changer in the making. Right now, clinical trial is clunky. Matching patients to trial is often manual, time consuming, laborious. You need a lot of personnel to do that. AI can automate this process by analyzing genomic data, medical records, and trial eligibility criteria to find the best matches quickly, accurately, and effectively. For the community, the key is to invest in data standardization and interoperability because AI needs clean, structured data to work effectively.

Dr. Pedro Barata and Dr. Ravin Garg discuss strategies to increase trial representation, including leveraging trial navigators and prioritizing pragmatic trial models, as featured in the ASCO Educational Book article, "Practical Guide to Clinical Trial Accessibility: Making Trial Participation a Standard of Care." TRANSCRIPT Dr. Pedro Barata: Hello, and welcome to By the Book, a podcast from ASCO featuring compelling perspectives from authors and editors of the ASCO Educational Book. I'm Dr. Pedro Barata. I am a medical oncologist at University Hospital Seidman Cancer Center and an associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I am also the associate editor of the ASCO Educational Book. We know that in recent years, the oncology community has increasingly prioritized the need to modernize clinical trial eligibility, reduce patient burden, and enhance diversity in trial participation. On that note, today we will be speaking about ways to enhance access to clinical trials with Dr. Ravin Garg. He is a hematologist oncologist at Maryland Oncology Hematology and also an assistant professor of oncology at Johns Hopkins Hospital in Baltimore. Dr. Garg is also the co-author of a fantastic paper in the ASCO Educational Book titled, "Practical Guide to Clinical Trial Accessibility: Making Trial Participation a Standard of Care."  Dr. Garg, welcome. Thanks for being here, and congrats on your paper. Dr. Ravin Garg: Thank you for having me, Pedro. I am excited to be here. Dr. Pedro Barata: [KI1]  Your paper is a wonderful, multidisciplinary piece that actually features perspectives from the different stakeholders, right? The patient advocacy, industry, community practice, and academia about these challenges in making trials more available. This podcast is a wonderful platform. It reaches out to a lot of folks within our community. So, I will start by asking you the obvious. Why do you think it is a must read for our community, for our listeners? Dr. Ravin Garg: So Pedro, thanks again for inviting me. You do a great job with these podcasts.  So, I think first and foremost, oncologists right now are under a lot of stress, just in terms of clinical volume. There is concern for research money, and how we get the best care for our patients. So I think this article is very important because it helps bring together, as you had mentioned, the stakeholders throughout academic to community practice and everywhere in between, and try to find how, as a team with different oncologists who partake in different aspects of oncology, can come together to streamline the process to try to get our patients on trials, or certainly have them have availability of trials, just if they are interested in going on them. Being in practice, we have had several challenges that we can talk about throughout this podcast, but I think it is a very important paper because it recognizes that at the end of the day, it takes a team effort for all of us in academics, community, industry, and pharmaceuticals to really come together as a team to really help put forth the trials for our patients. Dr. Pedro Barata: So, from the perspective of a community oncologist, how do you put together, or maybe you can describe some of the challenges that you see to increase trial participation in the community? Dr. Ravin Garg: Yes, Pedro, that is a great question, and it is something that I keep on thinking about and trying to find ways to be better at it myself. But I will say some of the challenges as a community doctor that I have seen for myself and talking to other colleagues. Number one, I do think there is a lot of stress on doctors in the community in general, Pedro. Oftentimes we are tasked to see a wide smorgasbord of patients, so we may not have the luxury of being a specialist in any particular tumor subtype. Like oftentimes, we will have to see lung cancer, the next one will be breast cancer, the next one could be CML, the next one could be thrombocytopenia. And as you know better than I do, Pedro, the field in each one of these disciplines is changing so rapidly: molecular genomics, radioligand treatments, different imaging tests, MRD testing for some of our hematologic malignancies. And I think one challenge we have in community is just keeping up with the basics of Oncology 101. In the process of doing that, it can be very difficult to sometimes remember that we have very exciting trials available for our patients. So, I think a lot of it is the day in and day out of being an oncologist is so taxing at times that oftentimes a research trial is not the first thing in our head space when we see a patient. I think number two, Pedro, at least in the community, and perhaps this is with academics too, is that we are bombarded, I would say, by a lot of messaging these days. We have in-baskets to go through, labs to go through, things of that nature. And in the process of a patient visit, seeing them, doing an exam, taking a history, trying to go over the NCCN guidelines on best practice for how to manage their care, at least for me at times, it is very hard to remember, "Hey, there might be a great trial available, whether within our network or maybe partnering with an academic center." So getting through a day can be fraught with a lot of peril and just difficulties, I would say. And I would say number three, Pedro, at least as, you know, I am in a private practice where I do see a wide range of benign and malignant hematology and solid tumors, so I would not call myself a specialist. And I think the challenge with that, at least for trials, Pedro, is that when you are a specialist or perhaps you are focusing on a couple of disease subtypes, you become more of an authoritative voice in those types of tumors, and you might be more aware of the trials within your network or perhaps in proxy with an academic center that you can offer your patient. So I think when sometimes we spread ourselves too thin, it can be very hard to be a thought leader, if you will, in a particular subtype of a malignancy, let's say, and maybe not be aware of a trial that could be really well-suited for your patient. In terms of ideas that myself and colleagues have had in terms of helping mitigate against some of these, I would say, setbacks or issues in the practice for trial enrollment, some of the things we have talked about, Pedro, is, number one, is we do partner with academic centers. So we live here in Maryland. We have several really fantastic academic centers. So, you know, oftentimes, not just within our practice of Maryland Oncology Hematology, we have a lot of great trials available here too, for certain, but in addition to that, we will often times work with doctors at Georgetown, Johns Hopkins, and Maryland if they have a compelling trial that we do not have within our network. It is really of the patient's interest, Pedro, to reach out to them in a collaborative manner to see if they have a trial that might be really compelling for your patient. So I do find myself collaborating a lot with colleagues in, like talented like yourself in academics. You know, I think you do a lot of GU malignancies. So as an example, like partnering with colleagues who are GU experts and say, "Hey, we have a patient with stage IV renal cell. These are the standard options I know, but are there any trials that you might have available?" I think the other thing that has been very helpful for us is having navigators within research, Pedro. Like as an example, what has really helped the uptake of trial enrollment for our center in Annapolis is having a research navigator because often times what they can do is, a priori, Pedro, before you see the patient and you are kind of formulating a standard of care treatment plan perhaps, they might tug you on the shirt and say, "Hey, we have a great trial here through Sarah Cannon, or there might be something else out there." And being aware of that when you go into a patient's room really provides a nice arena, if you will, to go and say, "The standard of care is here, but hey, we have a trial option that might be well suited for you, maybe perhaps even better, that we can talk about, too." So having research support in the community is really a huge boon, I think, Pedro, for us to really increase our enrollment for patients onto trials. Dr. Pedro Barata: Yes, I really love that, Ravin. So, let me switch gears a bit. I would love for you to talk a little bit about patient advocacy because they do play a huge role in cancer, and they address many barriers. How do you think we should leverage the patient advocacy groups to reduce patient burden and maybe have them really leverage patient advocacies to improve representation in clinical trials? What do we think we can do more? Dr. Ravin Garg: Oh, Pedro, I think they are very critically important. As a clinical oncologist now, and I would say this is for anyone in the field of medicine, you are exactly right. I think patients are bombarded by information. There are a lot of things online, whether it be TikTok, Facebook, Google, Yahoo, and people really just have a lot of information given to them. And some of it is fact driven, and some of it is not, Pedro. And oftentimes, I do think there can be at times a mistrust with some medical personnel. I think we are in an era where we are seeing that to some degree with some attributes of medicine. And I think of it as an opportunity for education for the patient and for myself as a physician. And I think patient advocates, to your point, which was well taken, serve as a bridge to both. And what I mean is that, you know, patient advocates are wonderful. They are, I think, outstanding communicators. They almost are a neutral party, Pedro, where many patients feel that they are an independent source of information that is free of bias, if you will. They are there to provide support, emotional support, scientific support for patients so they can make an informed decision. So, in terms of our practice right now, patient advocates is something that we are evolving in that capacity, I would say, Pedro. I think now more than ever, having more people as bridges of communication with care providers along with patients is of critical importance. And I would venture a guess, and I think this has been published, where patient advocates really can help tremendously in familiarizing patients with trials and what they are all about and maybe clear up some misconceptions of what trials, what the mission of trials are. Because I do think some patients, at least I have had a few over the years, where when they hear the term trial, they almost think they are being experimented upon, when, in point of fact, they could really help advance their care. That messaging along the way for some can may be mixed up a little bit. And so I think patient advocates is a really great way to offer more information for patients with a source they find very independent and trustworthy, if you will. And it can really help expedite, and I think make a more fruitful conversation for care providers, whether academic or community, and they might be more open-minded in terms of enrolling onto a trial. Dr. Pedro Barata: Wonderful. Yes, I agree. I agree with you completely.  So let's focus a little bit now on the folks designing the studies. We usually call them the sponsors. It might be an academic sponsorship, if you will, but we can also have pharma being the sponsor of a study. The angle from an academic design, it is not necessarily the same as what happens when we have pharma. And from that angle, how do you think a more inclusive research can be promoted? Dr. Ravin Garg: Oftentimes with trials, I think keeping them simple, as simple as we can. And what I mean by that is, often times for trials, Pedro, even for care providers who are enrolling, it can be daunting when there are a lot of different things involved, particularly, let's say, for investigator sponsored, which are incredibly brilliant science, incredible, but it can be a little bit daunting for patients and even the referring physician to talk about getting translational specimens, imaging, traveling to certain centers to get scans and biopsies and even different diagnostic testing like PSMA testing for, you know, prostate cancer. And it can, I think, be very intimidating for patients in terms of what might be required of him or her to enter onto a trial. Like, "This is not what I signed up for. This is laborious. This is a full time job for me. Do I have to pay for parking to go to a city? Do I have to pay for these imaging tests? And do I have to stay in a place for my family to enroll onto a trial?" So I think keeping trials as simple as possible, but yet cull the data we need as investigators where we can really advance the care, hopefully get approval for a drug, but also learn more about the medication and how it works for our patients. So I think simplifying language for trial is very important. I know when I have gone over studies for patients, Pedro, if it is a voluminous amount of information, they can right away get very intimidated. "Like, oh my goodness, this is like a term paper for college again," you know? I am joking, but you know, keeping language simplified is very important, I think, number one. And I feel that sometimes when they are asked to do a lot of different diagnostic testing, which is very important for translational work, I 100% understand, but I do think sometimes patients can get a little bit off put, if you will, and frustrated with the whole process of doing it. The second thing for our patients, Pedro, that they have mentioned to us when we put them on trials, not just within our own site but elsewhere, is that it takes a lot of time in terms of collecting information, perhaps a washout period from their last standard of treatment prior to enrollment onto a study. Many patients, Pedro, as you know better than I do, are in maybe crisis in terms of their health and their cancer might be growing, promulgating out of control, and they worry about not being able to expeditiously start onto a treatment, onto a trial. So that can lead to a lot of frustration. And one thing that you brought up, which was outstanding for me, is the enrollment criterion for some of our patients is felt to be somewhat strict. We have had some patients who may have had a remote history of a stage I malignancy that was by all accounts in remission, you know, let's say 4 or 5 years in the past, and the risk of recurrence at this point would be incredibly low, but they may not be able to enter onto a study because of some stringent criterion put forth. And that can be a little bit frustrating. In fact, I have had one or two patients who, as an example, with kidney issues, but the GFR was about 60, like right near a cutoff that oftentimes, as you know, we use where you can get into trial or not. And you know, if they are at 58, as an example, and otherwise they are a picture of health, a great candidate for a trial that will likely advance their care, and if the entry criterion is too stringent, that might be a lost opportunity for all parties involved, all stakeholders, if you will. I do appreciate the criterion for entry onto studies cannot be too liberalized. You have to have a certain baseline, but there is a little bit of a gray area and tension, of sorts, if you will, where the patient has a comorbid illness that is a disqualifying offense, but in practicality, perhaps it shouldn't be, especially if they are motivated and there is an opportunity to really advance their care. We have run into, not often, but sometimes in the past, I should say, where patients have been very off put because we try to get them onto a study and there may have been a particular feature or attribute in their underlying care that they couldn't get onto it. So I think having a little bit more thoughtfulness, perhaps, in terms of entry criterion and practicality, if you will, I think would really help enrollment onto studies. Dr. Pedro Barata: Really well said. Is there anything else that you would like to tell our listeners before we wrap up the podcast today? Dr. Ravin Garg: I would say just macroscopically speaking, it is really an honor to be an oncologist. I think I speak for both of us. Anyone listening who is thinking about the field, it is tremendous. Just the research, the bravery of our patients, and the thoughtfulness of our scientists like Pedro and translationalists and clinical trialists is really awe inspiring. So I have really loved this field. I will say from a trial perspective, we really need to enter as many patients as we can onto trials because the science is so brilliant now, the genomic underpinnings of the tumor, we are making great strides as a team of clinicians and scientists, translationalists. So the more that we can get people onto trials and get approved drugs, it is going to help them out in the end. So I think it is such an important time for all of us to come together as a community, find the best way to help our patients out. And clinical trials have to be at the forefront of how we can continue to advance care for our patients. Dr. Pedro Barata: Yeah, no Ravin, I really agree with you. We really need to increase access to clinical studies, and actually your paper is a great step in that direction by raising awareness, bringing up solutions, and again, collaboration, collaboration, collaboration is really a multidisciplinary effort to accomplish that.  Thank you so much for sharing your fantastic thoughts and insights with us. Dr. Ravin Garg: Thank you, Pedro. I am- you do a wonderful job with these podcasts. I am really honored to meet you and to be part of this. Dr. Pedro Barata: And thank you to our listeners for your time today. I encourage you to check out Dr. Garg's article in the 2025 ASCO Educational Book.

Dr. Pedro Barata and Dr. Aditya Bagrodia discuss the evolving landscape of testicular cancer survivorship, the impact of treatment-related complications, and management strategies to optimize long-term outcomes and quality of life. TRANSCRIPT:  Dr. Pedro Barata: Hello and welcome to By the Book, a podcast series from ASCO that features engaging conversations between editors and authors of the ASCO Educational Book. I'm Dr. Pedro Barata. I'm a medical oncologist at University Hospitals Seidman Cancer Center and associate professor of medicine at Case Western Reserve University in Cleveland, Ohio. I'm also an associate editor of the ASCO Educational Book. We all know that testicular cancer is a rare but highly curable malignancy that mainly affects young men. Multimodal advances in therapy have resulted in excellent cancer specific survival, but testicular cancer survivors face significant long term treatment related toxicities which affect their quality of life and require surveillance and management. With that, I'm very happy today to be joined by Dr. Aditya Bagrodia, a urologic oncologist, professor, and the GU Disease Team lead at UC San Diego[KI1]  Health, and also the lead author of the recently published paper in the ASCO Educational Book titled, "Key Updates in Testicular Cancer: Optimizing Survivorship and Survival." And he's also the host of the world-renowned BackTable Urology Podcast. Dr. Bagrodia, I'm so happy that you're joining us today. Welcome. Dr. Aditya Bagrodia: Thanks, Pedro. Absolutely a pleasure to be here. Really appreciate the opportunity. Dr. Pedro Barata: Absolutely.  So, just to say that our full disclosures are available in the transcript of this episode.  Let's get things started. I'm really excited to talk about this. I'm biased, I do treat testicular cancer among other GU malignancies and so it's a really, really important topic that we face every day, right? Fortunately, for most of these patients, we're able to cure them. But it always comes up the question, "What now? You know, scans, management, cardio oncology, what survivorship programs we have in place? Are we addressing the different survivorship piece, psychology, fertility, et cetera?" So, we'll try to capture all of that today. Aditya, congrats again, you did a fantastic job putting together the insights and thoughts and what we know today about this important topic. And so, let's get focused specifically about what happens when patients get cured. So, many of us, in many centers, were fortunate enough to have these survivorship programs together, but I find that sometimes from talking to colleagues, they're not exactly the same thing and they don't mean the same thing to different people, to different institutions, right? So, first things first. What do you tell a patient perhaps when they ask you, "What can happen to me now that I'm done with treatment for testicular cancer?" Whether it's chemotherapy or just surgery or even radiation therapy? "So, what about the long term? What should I expect, Doctor, that might happen to me in the long run?" Dr. Aditya Bagrodia: Totally. I mean, I think that question's really front and center, Pedro, and really appreciate you all highlighting this topic. It was an absolute honor to work with true thought leaders and the survivorship bit of it is front and center, in my opinion. It's really the focus, you know, we, generally speaking should be able to cure these young men, but it's the 10, 15, 20 years down the way that they're going to largely contend with. The conversation really begins at diagnosis, pre-education. Fortunately, the bulk of patients that present are those with stage one disease, and even very basic things like before orchiectomy, talking about a prosthetic; we know that that can impact body image and self esteem, whether or not they decide to receive it or not. Actually, just being offered a prosthetic is important and this is something, you know, for any urologist, it's kind of critical. To discussing fertility elements to this, taking your time to examine the contralateral testicle, ask about fertility problems, issues, concerns, offer sperm banking, even in the context of a completely normal contralateral testicle, I think these things are quite important.  So if it's somebody with stage one disease, you know, without going too far down discussing adjuvant therapy and so forth, I will start the conversation with, "You know, the testes do largely two things. They make testosterone and they make sperm." By and large, patients are going to be able to have acceptable levels of testosterone, adequate sperm parameters to maintain kind of a normal gonadal state and to naturally conceive, should that be something they're interested in. However, there's still going to be, depending on what resource you look at, somewhere in the order of 10-30% that are going to have issues. Where I think for the stage one patients, it's really incumbent upon us is actually to not wait for them to discuss their concerns, particularly with testosterone, which many times can be a little bit vague, but to proactively ask about it every time. Libido, erectile quality, muscle mass maintenance, energy, fatigue. All of these are kind of associated symptoms of hypogonadism. But for a lot of kids 18-20 years old, it's going to be something insidious that they don't think about. So, for the stage one patients, it absolutely starts with gonadal function. If they are stage two getting surgery, I think the counseling really needs to center around a possibility for ejaculatory dysfunction. Now, for a chemotherapy-naive, nerve-sparing RPLND, generally these days we should be able to preserve ejaculatory function at high volume centers, but you still want to bring that up and again kind of touch base on thinking about sperm banking and so forth before the operation, scars, those are things I think worth talking about, small risk of ascites. Then, I think the intensity of potential long term adverse effects really ramps up when we're talking about systemic therapy, chemotherapy. And then there's of course some radiation therapy specific elements that come up. So, for the chemotherapy bits of it, I really think this is going to be something that can be a complete multi-system affected intervention. So, anxiety, depression, our group has actually shown using some population resources that even suicidality can be increased among patients that have been treated for germ cell tumor. You know, really from the top down, tinnitus, hearing changes, those are things that we need to ask about at every appointment. Neuropathy, sexual health, that we kind of talked about, including ED (erectile dysfunction), vertigo, dizziness, Raynaud's phenomenon, these are kind of more the symptoms that I think we need to inquire about every time. And what we do here and I think at a lot of survivorship programs is use kind of a battery of validated instruments, germ cell tumor specific, platinum treated patient specific. So we use a combination of EORTC questions and PROMIS questions, which actually serves as like a review of systems for the patient, also as a research element. We review that and then depending on what might be going on, we can dig into that further, get them over to colleagues in audiology or psychology, et cetera.  And then of course, screening for the hypertension, hyperlipidemia, metabolic syndrome with basically you or myself or somebody kind of like us serving, many times it's the role of the PCP, just making sure we're checking out, you know, CBC, CMP, et cetera, lipid parameters to screen for those kind of cardiac associated issues along with secondary malignancies. Dr. Pedro Barata: So that's super comprehensive and thorough. Thank you so much. Actually, I love how you break it down in a simple way. Two functions of the testes, produce testosterone and then, you know, the problem related to that is the hypogonadism, and then the second, as you mentioned, produce sperm and of course related to the fertility issues with that.  So, let's start with the first one that you mentioned. So, you do cite that in your paper, around 5-10% of men end up getting, developing hypogonadism, maybe clinical when they present with symptoms, maybe subclinical. So, I'm wondering, for our audience, what kind of recommendations we would give for addressing that or kind of thinking of that? How often are you ordering those tests? And then, when you're thinking about testosterone replacement therapy, is that something you do immediately or are there any guidelines into context that? How do you approach that? Dr. Aditya Bagrodia: So, just a bit more on digging into it even in terms of the questions to ask, you know, "Do you have any decrease in sexual drive? Any erectile dysfunction? Are your morning erections still taking place? Has the ejaculate volume changed? Physically, muscle mass, strength? Have you been putting on weight? Have you noticed increase in body fat?" And sometimes this is complicated because there's some anxiety that comes along with a cancer diagnosis when you're 20, 30 years old, multifactorial, hair loss, hot flashes, irritability. Sometimes they'll, you know, literally they'll say, "You know, my significant other or partners noticed that I'm really just a little bit labile." So I think, you know, there's the symptoms and then checking, usually kind of a gonadal panel, FSH, LH, free and total testosterone, sex hormone binding globulin, that's going to be typically pretty comprehensive. So if you've got symptoms plus some laboratory work, and ideally that pre-orchiectomy testosterone gives you some delta. If they started out at an 800, 900, now they're 400, that might be a big change for them. And then, when you talk about TRT (Testosterone Replacement Therapy) recommendations, you know, Pedro, yourself, myself, we're kind of lucky to be at academic centers and we've got men's health colleagues that are ultra experts, but at a high level, I would say that a lot of the TRT options center around fertility goals. Exogenous testosterone treats the low T, but it does suppress gonadal function, including spermatogenesis. So if that's not a priority, they can just get TRT. It should be done under the care of a urologist, a men's health, an endocrinologist, where we're checking liver chemistries and CBCs and a PSA and so forth. If they're interested in fertility preservation, then I would say engaging an endocrinologist, men's health expert is important. There's medications even like hCG, Clomid, which works centrally and stimulate the gonadal access. Niche scenarios where they might want standard TRT now, and then down the way, 5, 7 years, they're thinking about coming off of that for fertility purposes, I think that's really where you want to have an expert involved because there's quite a bit of nuance there in recovery of actual spermatogenesis and so forth.  To kind of summarize, you got to ask about it. Checking it is, is not overly complicated. We do a baseline pre-orchiectomy and at least once annually, you can tag it in with the tumor markers, so it's not an extra blood draw. And if they have symptoms of course, kind of developed, then we'll move that up in the evaluation. Dr. Pedro Barata: Got it. And you also touch base on the fertility angle, which is truly important. And I'm just curious, you know, a lot of times many of us might see one, two patients a year, right, and we forget these protocols and what we've got to do about that.  And so I'm interested to hear your thoughts about when you think about fertility, and how proactive you get. In other words, who do you refer for the fertility clinic, for a fertility preservation program? You know, do all cases despite getting through orchiectomy or just the cases that you're going to, you know you're going to seek chemotherapy at some point? What kind of selection or it depends on the chemo, like how do you do that assessment about the referral for preservation program that you might have available at UCSD? Dr. Aditya Bagrodia: Yeah, I mean I feel really fortunate to sit on the NCCN Testis Cancer Guidelines. It's in there that fertility counseling should be discussed prior to orchiectomy. So 100% bring it up. If there are risk factors, undescended testicles, previous history of fertility concerns, atrophic contralateral testicle, anything on the ultrasound like microlithiasis in the contralateral testicle, you kind of wanna get it there. And then again, there's kind of niche scenarios where you're really worried, maybe get a semen analysis and it doesn't look that good, arrange for the time of orchiectomy to have onco-testicular sperm extraction from the, quote unquote, "normal" testis parenchyma. You know, I think you have to be kind of prepared to go that route and really make sure you're doing this completely comprehensively.  So pre-orchiectomy all patients. Don't really push for it too hard if they've got a contralateral testicle, if they've had no issues having children. There's some cost associated with this, sperm banking still isn't kind of covered even in the context of men with cancer. If they've got risk factors, absolutely pre-orchiectomy. Pre-RPLND, even though the rates of ejaculatory dysfunction at a high-volume center should be low single digits, I'll still offer it. That'd be a real catastrophe if they were in that small proportion of patients and now they're going to be reliant on things like intrauterine insemination, where it becomes quite expensive.  Pre-chemo, everybody. That's basically a standard these days where it should be discussed and it's kind of amazing currently, even if you don't have an accessible men's health fertility clinic, there are actually companies, I have no vested interest, Fellow is one such company where you can actually create an account, receive a FedEx semen analysis and cryopreservation kit, send it back in, and all CLIA certified, it's based out of California. The gentleman that runs it, is a urologist and very, very bright guy who's done a lot of great stuff for testis cancer. So, even for patients that are kind of in extremis at the hospital that kind of need to get going like yesterday, we still discuss it. We've got some mechanisms in place to either have them take a semen analysis over to our Men's Health clinic or send it off to Fellow, which I think is pretty cool and that even extends to some of our younger adolescent patients where going to a clinic and providing a sample might be tricky.  So, I think bringing it up every stage, anytime there's an intervention that might be offered, orchiectomy, chemo, surgery, radiation, it's kind of incumbent on us to discuss it. Dr. Pedro Barata: Gotcha. That's super helpful. And you also touch base on another angle, which is the psychosocial angle around this. You mentioned suicidal rates, you mentioned anxiety, perhaps depression in some cases as well as chronic fatigue, not necessarily just because of the low testosterone that you can get, but also from a psychological perspective. I'm curious, what do the recommendations look like for that? Do these patients need to see a social worker or a psychologist, or do they need to answer a screening test every time they come to see us and then based on that, we kind of escalate, take the next steps according to that? Do they see a psychologist perhaps every so often? How should that be managed and addressed? Dr. Aditya Bagrodia: It's an excellent question and again, these can be rather insidious symptoms where if you don't really dig in and inquire, they can be glossed over. I mean, how easy to say, "Your markers look okay, your scans look okay. See you in six months," and keep it kind of brief. First off, I think bringing it up proactively and normalizing it, that, "This may be something that you experience. Many people do, you're not alone, there's nothing kind of wrong with you." I also think that this is an area where support groups can be incredibly useful. We host the Testicular Cancer Awareness Foundation support group here. They'll talk about chemo brain or just like a little bit of an adjustment disorder after their diagnosis. Support groups, I think are critical. As I mentioned, we have a survivorship program that's led by a combination of our med oncs, myself on the uro-onc side, as well as APPs, where we are systematically asking about essentially the whole litany of issues that may arise, including psychosocial, anxiety, depression, suicidality. And we've got a nice kind of fast path into our cancer center support services for these young men to meet with a psychologist. If that isn't going to be sufficient, they can actually see a psychiatrist to discuss medications and so forth. I do think that we've got to screen for these because, as anticipated from diagnosis, those first 2 years, we see a rise. But even 10, 15 years out, we note, compared to controls, that there is an increased level of anxiety, depression, suicidality that might not just take place at that initial acute period of diagnosis and treatment. Dr. Pedro Barata: Really well said. Super important.  So I guess if I were to put all these together, with these really amazing advances in technology, we all know AI, some of us might be more or less aware of biomarkers coming up, including microRNA for example, and others, like as I think of all these potential long term complications for these patients, look at the future, I guess, can we use this as a way to deescalate treatment where it's not really necessary, as a way to actually prevent some of these complications? Like, how do we see where we're heading? As we manage testicular cancer, let's say, within the next 5 or 10 years, do you think there's something coming up that's going to be different from what we're doing things today? Dr. Aditya Bagrodia: Totally. I mean, I think it's as exciting as a time as there's ever been, you know, maybe notwithstanding circa 1970s when platinum was discovered. So microRNAs, which you mentioned, you know, there's a new candidate biomarker, microRNA-371. We are super excited here at UCSD. We actually have it CLIA-certified available in our lab and are ordering these tests for patients kind of in their acute stage, you know, stage one and surveillance, stage two, post-RPLND, receiving chemotherapy. And essentially this is a universal germ cell tumor specific biomarker, except for teratoma, suffice it to say 90% sensitive and specific. And I think it's going to change the way that we diagnose and manage patients. You know, pre-orchiectomy, that's pretty straightforward. Post-orchiectomy, maybe we can really decrease the number of CT scans that are done. Maybe we can identify those patients that basically have occult disease where we can intervene early, either with RPLND or single cycle chemo. Post-RPLND, identify the patients who are at higher risk of relapse that may benefit from some adjuvant therapy. In the advanced setting, look at marker decline for patients in addition to standard tumor markers. Can we modulate their systemic therapy?  So, the international interest is largely on modifying things. There's really cool clinical trials that we have for stage one patients, that treatment would be prescribed based on a post-orchiectomy microRNA. I think the microRNAs are really exciting. Teratoma remains an outstanding question. I think this is where maybe ctDNA, perhaps some radiomics and advanced imaging processing and incorporating AI may allow us to safely avoid a lot of these post-chemo RPLNDs. And then identification using SNPs and so forth of who might be most susceptible to some of the cardiac toxicity, autotoxicity and personalizing things in that way as well. Dr. Pedro Barata: Super exciting, right, what's about to come? And I agree with you, I think it's going to change dramatically how we manage this disease.  This has been a pleasure sitting down with you. I guess before letting you go, anything else you'd like to add before we wrap it up? Dr. Aditya Bagrodia: Yeah, first off, again, just want to thank you and ASCO for the opportunity. And it's easy enough to, I think, approach a patient with the testicular germ cell tumor as, "This is an easy case. We're just going to do whatever we've done. Go to the guidelines that says do X, Y, or Z." But there's so much more nuance to it than that. Getting it done perfectly, I think, is mandatory. Whatever we do is an impact on them for the next 50, 60, 70 years of their life. And I found the germ cell tumor community, people are really passionate about it. If you're ever uncertain, there's experts throughout the country and internationally. Ask somebody before you do something that you can't undo. I think we owe it to them to get it perfect so that we can really maximize the survivorship and the survival like we've been talking about. Dr. Pedro Barata: Aditya, thanks for sharing your fantastic insights with us on this podcast. Dr. Aditya Bagrodia: All right, Pedro. Fantastic. Appreciate the opportunity. Dr. Pedro Barata: And also, thank you to our listeners for your time today. I actually encourage you to check out Dr. Bagrodia's article in the 2025 ASCO Educational Book. We'll post a link to the paper in the show notes. Remember, it's free access online, and you can actually download it as well as a PDF. You can also find on the website a wealth of other great papers from the ASCO Educational Book on key advances and novel approaches that are shaping modern oncology.  So with that, thank you everyone. Thank you, Aditya, one more time, for joining us. Thank you, have a good day. Disclaimer: The purpose of this podcast is to educate and to inform.
