Highlights From the 2026 ASCO GU Cancers Symposium

Dr. Monty Pal and Dr. Andrea Apolo discuss practice-changing studies and other novel approaches in bladder, kidney, and prostate cancers that were presented at the 2026 ASCO Genitourinary Cancers Symposium. TRANSCRIPT Dr. Monty Pal: Hello and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist, professor and vice chair of academic affairs at the City of Hope Comprehensive Cancer Center in Los Angeles. And today is super exciting, we're highlighting key abstracts that were presented at the 2026 ASCO GU Cancers Symposium, and I'm just delighted to be joined by the chair of this year's meeting, who is also a dear friend, Dr. Andrea Apolo. Dr. Apolo serves within the Center for Cancer Research at the NCI as head of the Bladder Cancer Section, and she is also acting deputy chief of the Genitourinary Malignancies Branch. Welcome, Andrea, it is so great to have you on the podcast. Dr. Andrea Apolo: Oh, thank you so much for having me. What a great ASCO that we had, it is really exciting, lots of really great data. So I look forward to chatting about it. Dr. Monty Pal: Excellent. And you know, our full disclosures are available in the transcript of this episode in case our listeners want to have a peek. The theme of this year's GU meeting was "Patient-Centered Care: From Discovery to Delivery." I love that theme. And really, this is one of the most competitive meetings out there, more than 850 abstracts being presented on high-impact science. Andrea, I just wanted to get right into it and dive into what I think we both felt were some of the most exciting abstracts of the meeting. And the first of those is one that I know is near and dear to your heart, being a bladder cancer expert yourself, and that is the KEYNOTE-B15 study presented by Matt Galsky. Can you give us a flavor for what that study entailed and some of the key results? Dr. Andrea Apolo: Yeah, I think this was kind of the missing study that we have been waiting for since we saw the EV-302 data in metastatic disease in the frontline setting. We wanted to know how well this combination would work in muscle-invasive bladder cancer patients. And we saw half of that puzzle, you can say half of the piece of the puzzle, when we saw the data at ESMO, the EV-303 data in patients that were cisplatin-ineligible. And then now we are getting the full story with patients that are platinum-eligible, cisplatin-eligible, with the EV-304 data. So that study randomized patients to receive chemotherapy, so different than the EV-303 where the patients were randomized just to receive the radical cystectomy. These patients were randomized to receive neoadjuvant EV plus pembro and then adjuvant EV plus pembro versus neoadjuvant gemcitabine and cisplatin with no adjuvant component to the control arm. So I think this is a really, really important study. Dr. Monty Pal: And share with us some of the results because this in my mind is definitely practice-changing. This is one of those studies that I think you walked into the office on Monday and you are like, "Okay, this is what I am doing now," right? Dr. Andrea Apolo: Yeah. So the study was positive. The primary endpoint was event-free survival, and it met the primary endpoint. The secondary endpoint of overall survival was also met. So really, really great results. Consistent with what we saw with EV-303, the median event-free survival was not reached for the EV plus pembro arm, and it was 48 months for the patients receiving gem-cis. And then looking at the 24-month estimated event-free survival, it was 79% for the EV plus pembro and 66% for the chemo, the gem-cis arm. And that was a hazard ratio of 0.5. So that is really exciting. That is the event-free survival. And then the overall survival, the medians were not reached for either arm, but when you look at the 24-month estimated overall survival, it was 87% for the EV plus pembro versus 81% for the gem-cis, and that was a hazard ratio of 0.65. So very positive study. And then another question that we had was the pathologic CR rate. Very consistent with what we saw with the EV-303, the pathologic response rate was about 56% for the patients that received EV plus pembro and about 32%, 33% for the patients that received gem-cis. So very consistent with the findings that we have been kind of seeing in phase 2 studies, and this is a pT0N0, so that is important. Dr. Monty Pal: So Andrea, you know, I think that the big question in folks' minds is at this point, we see the data from NIAGARA, cis-gem-durva, we have now seen this data. Put it into context for us. Is there a patient in this day and age who maybe shouldn't get IO altogether, who should maybe get the NIAGARA regimen as opposed to EV-pembro in this context? What are your thoughts there? Dr. Andrea Apolo: Now, that is a great question. I would say with this data, it is very enticing to give EV pembro to our patients in the perioperative setting, and for that to be the new standard of care for all patients, regardless of cisplatin eligibility. So similar to what we saw with EV-302 really changing the standard of care in the frontline setting, I think these two studies, the EV-303 and the EV-304, change the standard of care for patients with muscle-invasive bladder cancer in the perioperative setting, and this should be the new standard of care if the patients don't have a restriction to receiving an immunotherapy. Dr. Monty Pal: I totally agree with that assessment. It is great to hear it from the expert's mouth as well. Thanks a lot for that, Andrea. The next abstract I wanted to tackle is one that is, I would say, near and dear to my heart because I know these folks really well. It is led by the SWOG group, and this is SWOG S1602. The number there for the audience gives you a sense of how long the study has been running for. The 16 prefix means it is something that we kicked off back in 2016. So this study is really 10 years in the making, right? So Rob Svatek presented this data. It is interesting, right, because it addresses this issue of the BCG (Bacille Calmette-Guérin) shortage, right, where we have needed to sort of rely potentially on other alternative sources or regimens and so forth. Tell us about this trial, Andrea. Dr. Andrea Apolo: This is one of my favorite studies. We talked about putting it in the main oral abstracts, but we put it in one of the educational sessions that talked about non-muscle-invasive bladder cancer because we thought that would be the best audience for it. But it doesn't take away from how important this abstract is, and the tremendous effort that went into the study. Almost a thousand patients enrolled. I think 984 were eligible to enroll in this study. So it is a very high enrolling, randomized, cooperative group study in high-grade non-muscle-invasive bladder cancer. And really the study was designed to address two questions. One is the BCG shortage and can we use a different strain, Tokyo versus TICE? And whether there is a priming effect if you gave intradermal BCG to patients with non-muscle-invasive bladder cancer, can that enhance the effect if you gave it a little bit earlier? I think the study is really important, and it met its primary endpoint, which was it is not inferior to TICE. The findings were really terrific in terms of the outcomes. Numerically. When you look at the endpoint, it looked like the Tokyo strain was as good, if not maybe a little bit better, but not statistically significant than the TICE. And then they broke it down by carcinoma in situ, they broke it down by papillary tumors, and the Tokyo strain was non-inferior in both of those instances. But interestingly, the intradermal BCG did not change outcomes. There was really no priming effect, which was really backed up by pre-clinical data that there would be, but there wasn't a priming effect when the intradermal BCG was given in the Tokyo strain. So that was a really, really interesting finding. But a great study, really important outcomes in the field for non-muscle-invasive bladder cancer. Dr. Monty Pal: Totally. And it just seems like we can't get away from BCG, right? You know, as hard as we try, I mean, I appreciate the studies that sort of build on it that are emerging right now, but it seems like BCG at least for the foreseeable future is kind of here to stay, right? Dr. Andrea Apolo: It works. It is one of the most effective treatments we have for non-muscle-invasive bladder cancer. So, you know, I think it is here to stay and, you know, we need to find alternatives in terms of strains so we don't deal with this shortage that we have been dealing with for so many years now. Dr. Monty Pal: Yeah, indeed. Moving on to some of the other highlighted studies from the meeting, you had mentioned the EV-303 data, so we probably don't need to rehash that study design in much detail. But there was also a rapid oral abstract presented by Dr. Ullén that I think is of interest here, right, that really hones in on pathologic outcomes and DFS from that trial. Do you mind just outlining that for our listenership? Dr. Andrea Apolo: This is the KEYNOTE-905, also known as the EV-303 study. This is a follow-up to the EV-303 data looking at the pathologic response rates, looking at the downstaging effect, looking at the surgical margins after treatment with the neoadjuvant EV plus pembro in the 303. Now, remember in the 303, patients got three cycles of neoadjuvant EV plus pembro and then six cycles in the adjuvant setting. A little bit different than the 304, where they got four cycles, which is really kind of the standard in the neoadjuvant setting, and then five cycles in the adjuvant setting. So still a total of nine cycles. But in the 303, the treatment arm had no systemic therapy, so it was just radical cystectomy. And they looked at the negative margins that you get with the EV plus pembro treatment, which was 92.6% ve

Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer Guideline Update

Dr. Lakshmi Rajdev and Dr. Manish Shah join the podcast to discuss the updated guideline on immunotherapy and targeted therapy in unresectable locally advanced, advanced, or metastatic gastroesophageal cancer. They share first-line and subsequent-line recommendations for both gastroesophageal adenocarcinoma and esophageal squamous cell carcinoma based on actionable biomarkers including PD-L1 expression, MMR and/or MSI, CLDN18.2 expression, and HER2 status. They note the importance of the algorithms and tables in the guidelines that provide visual illustrations and quick reference guides of the evidence-based recommendations. They also comment on ongoing and recently presented trials that may impact future guidelines in this space. Read the full guideline, "Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer: ASCO Guideline Update" at www.asco.org/gastrointestinal-cancer-guidelines" TRANSCRIPT This guideline, clinical tools and resources are available at www.asco.org/gastrointestinal-cancer-guidelines.

You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I am interviewing Dr. Lakshmi Rajdev from the Icahn School of Medicine at Mount Sinai and Dr. Manish Shah from Weill Cornell Medicine, co-chairs on "Immunotherapy and Targeted Therapy for Advanced Gastroesophageal Cancer: ASCO Guideline Update." Thank you for being here today, Dr. Rajdev and Dr. Shah. Dr. Lakshmi Rajdev: Thank you. Dr. Manish Shah: Thank you for having us. It is wonderful. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Rajdev and Dr. Shah, who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into what we are here today to talk about, Dr. Shah, I would like to start first with what prompted the update to this guideline, which was previously published in 2023, and what is the scope of this updated guideline? Dr. Manish Shah: Yes, terrific. So even in the last few years, the pace of drug development in gastroesophageal cancers has just been astounding. So, what prompted this guideline is actually the practice-changing results for a new biomarker, CLDN18.2 hat was based on the GLOW and SPOTLIGHT studies, as well as a practice-changing study in HER2-positive disease where we added pembrolizumab to trastuzumab and chemotherapy for tumors that are HER2-positive and PD-L1 CPS 1 or greater. And then there were also new studies and new approvals in esophageal squamous cell cancer that you will hear about as well. So there were several studies, overall more than 5,000 patients were reported on, and that led to several new therapies, new indications, and it really necessitated this guideline. Brittany Harvey: Excellent. It is great to hear about all of these exciting updates in this space. So then to next review the key recommendations of this guideline by clinical question that the expert panel addressed. So, Dr. Rajdev, what is the recommended first-line treatment for patients with proficient mismatch repair, microsatellite stable, HER2-negative gastroesophageal adenocarcinoma? Dr. Lakshmi Rajdev: Thank you for that question. So historically, we have sort of used fluoropyrimidine and platinum doublets, which yielded a survival of about one year. More recently, immunotherapy and targeted therapy options have improved outcomes in patients with advanced esophageal and gastric adenocarcinoma, as well as squamous cell carcinoma. Patients with gastric and GE junction adenocarcinoma have a high rate of actionable alterations, so it is imperative that physicians test the following biomarkers upfront so that it can help guide therapy. The markers recommended by the ASCO panel are HER2, MMR or MSI, CLDN18.2, and PD-L1. And also, it was recommended to use NGS if feasible in this patient population. HER2, as we know, is expressed in about 15% to 25% of patients; PD-L1 expression occurs in about 80% of patients; MSI-high, deficient MMR is present in about 5% to 8% of patients; and CLDN18.2 expression is present in about 40% of patients. There is, of course, biomarker overlap. About 13% to 22% of CLDN18.2 patients are also PD-L1 positive. For patients with pMMR or microsatellite stable HER2-negative disease with PD-L1 expression greater than 1 and absence of CLDN18.2, the panel recommended a first-line therapy with fluoropyrimidine and platinum-based therapy in combination with immunotherapy. These recommendations stem from large phase 3 trials, and the agents approved in the United States are pembrolizumab, nivolumab, and tislelizumab. It has been shown that immunotherapy benefit is greater in patients with higher PD-L1 expression, and it is not possible to comment on the individual PD-L1 cutoff scores and sort of identify the optimal PD-L1 cutoff score that sort of balances benefits and harms. But what is recommended is that immunotherapy-based treatments can be offered in patients with a CPS score of greater than 1. With regard to the choice of immunotherapy agents, that is pembrolizumab, nivolumab, or tislelizumab, these agents are considered to have similar efficacy, and the selection of an agent could be based on dosing schedule, cost considerations, toxicity, and the method of administration. Typically, clinicians should avoid withholding the start of chemotherapy while awaiting biomarker testing, depending on the clinical scenario. Now, for patients with pMMR microsatellite stable disease that is HER2-negative with PD-L1 expression less than 1 and positive CLDN18.2 expression, zolbetuximab-based treatments or in combination with chemotherapy is recommended, and this is based on two global phase III randomized controlled trials, the GLOW and the SPOTLIGHT. And across both studies, the hazard ratio for the overall survival was 0.78, and similarly, there was also an improvement in progression-free survival favoring the zolbetuximab group compared to the chemotherapy group alone. An important note is that nausea, vomiting is commonly associated with zolbetuximab-based treatments, and the panel recommended prophylactic antiemetics, adjusting zolbetuximab infusion rates, pausing infusion temporarily, using non-prophylactic antiemetics, and hydration intravenously prior to discontinuation of zolbetuximab-based chemotherapy. So effective handling of the GI-related symptoms with zolbetuximab is recommended prior to discontinuation of therapy. Now, for patients with pMMR microsatellite stable HER2-negative gastric, GE junction adenocarcinoma with PD-L1 expression greater than 1 and CLDN18.2 positivity, the ones with the dual expression with CLDN18.2 as well as PD-L1 chemotherapy, the choice of therapy can be based on the degree of PD-L1 expression, the toxicity profile, the burden of symptoms, and the anticipated improvement in symptoms associated with response to treatment, the patient comorbidities, the prior medical and treatment history. So this decision needs to be made on a case-by-case basis, and these are some of the factors that we suggested that could potentially influence the choice of therapy. For patients with pMMR microsatellite stable disease that is HER2-negative and a PD-L1 expression less than 1 and an absence of CLDN18.2 expression, first-line therapy with fluoropyrimidine and platinum-based chemotherapy is recommended. So you can see we have segmented out patients based on PD-L1 expression, pMMR and microsatellite stable disease expression, and also based on CLDN expression. Brittany Harvey: Absolutely. And that first point you noted, I think is really important, that biomarker testing is really critical for treatment decision-making in this space. So then the next subgroup of patients that the panel looked at, Dr. Shah, what first-line therapy is recommended for patients with proficient mismatch repair, microsatellite stable, HER2-positive gastroesophageal adenocarcinoma? Dr. Manish Shah: So this was an update from a few years ago. So we have known for 15 years now that if you are HER2-positive, you should get trastuzumab plus chemotherapy. That was based on the ToGA trial. And the update now is based on a trial called KEYNOTE-811, where it examined the addition of pembrolizumab to trastuzumab and chemotherapy versus trastuzumab and chemotherapy, and there was a progression-free and overall survival benefit. And again, here, the biomarkers are important. If your CPS PD-L1 is l

Expanding Treatment Options for Breast Cancer: ADCs and Oral SERDs

Dr. Monty Pal and Dr. Hope Rugo discuss advances in antibody-drug conjugates for various breast cancer types as well as treatment strategies in the new era of oral SERDs for HR-positive breast cancer. TRANSCRIPT Dr. Monty Pal: Hello, and welcome to the ASCO Daily News Podcast. I'm your host, Dr. Monty Pal. I'm a medical oncologist and vice chair of academic affairs here at the City of Hope Comprehensive Cancer Center, Los Angeles. Today, I'm thrilled to be joined by Dr. Hope Rugo, an internationally renowned breast medical oncologist and my colleague here at City of Hope, where she leads the Women's Cancers Program and serves as division chief of breast medical oncology. Dr. Rugo is going to share with us exciting advances in antibody-drug conjugates (ADCs) that are expanding treatment options in various breast cancer types. She'll also address some of the complex questions arising in the new era of oral SERDs (selective estrogen receptor degraders) that are revolutionizing treatment in the hormone receptor-positive breast cancer space. Our full disclosures are available in the transcript of this episode. Dr. Rugo, welcome, and thanks so much for being on the podcast today. Dr. Hope Rugo: Thank you. Pleasure to be here. Dr. Monty Pal: So, I'm going to switch to first names if you don't mind. The first topic is actually a really exciting one, Hope, and this is antibody-drug conjugates. I don't know if I've ever shared this with you, but I actually started my training at UCLA, I was a med student and resident there, and it was in Dennis Slamon's lab. I worked very closely with Mark Pegram and a handful of others. This is right around the time I think a lot of HER2-directed therapies were really evolving initially in the clinics. Now we've got antibody-drug conjugates. Our audience is well-familiar with the mechanism there but tell us about how ADCs have really started to reshape therapy for HER2-positive breast cancer. Dr. Hope Rugo: Yeah, I mean, this is a really great place to start. I mean, we have had such major advances in breast cancer just this year, I think really changing the paradigm of treating patients. But HER2-positive disease, we've been used to having sequenced success of new agents. And I think the two biggest areas where we've made advances in HER2-positive disease, which were remarkably advanced this year in 2025, have been in antibody-drug conjugates with trastuzumab deruxtecan and with new oral tyrosine kinase inhibitors (TKIs) that have less of a target on EGFR and more on HER2, so they have an overall more tolerable toxicity profile and therefore a potentially better efficacy in the clinic. At least that's what we're seeing with these new strategies that we couldn't really pursue in the past because of toxicities of the oral TKIs. So, although our topic is ADCs, I'm going to include the TKI because it's so important in our thinking about treating HER2-positive disease. In the metastatic setting, we've seen these remarkable improvements in progression-free and overall survival in the second-line setting with T-DXd, or trastuzumab deruxtecan, compared to T-DM1. And then sequencing ADCs with giving T-DXd after T-DM1 was better than an oral tyrosine kinase or a trastuzumab combination with standard chemotherapy. That was DESTINY-Breast03 and DESTINY-Breast02. So, then we've had other trials since then, and T-DXd has moved into the early-stage setting, which I'll talk about in just a moment. But the next big trial for T-DXd in HER2-positive disease was moving it to the first-line setting to supplant what has become an established treatment for now quite a long time: the so-called CLEOPATRA regimen, which used the combined antibodies trastuzumab, pertuzumab with a taxane as first-line therapy. And then we've proceeded on with maintenance with ongoing HP for patients with responding or stable disease. And we'd seen long-term data showing, you know, at 8 years there was a group of patients whose cancers had never progressed and continued improved overall survival. So, T-DXd was studied in DESTINY-Breast09, either alone or in combination with pertuzumab compared to THP. The patient population had received a little bit more prior treatment, but interestingly, not a lot compared to CLEOPATRA. And they designed the trial to be T-DXd continued until progression with or without pertuzumab versus THP, which would go for six cycles and then stop around six cycles, and then stop and continue HP. Patients who had hormone receptor-positive disease could use hormone therapy, and this is one of the issues with this dataset because, surprisingly in this dataset and one other I'll mention, very few patients took hormone therapy. And even in the maintenance trial, the HER2CLIMB-05, less than 50% took hormone therapy as maintenance. This is kind of shocking to me and highlights an area of really important education, that outcome is improved when you add endocrine therapy for hormone receptor-positive HER2-positive metastatic disease in the maintenance phase, and it's a really important part of treatment. But suffice it to say, you know, you're kind of studying continued chemo versus stopping chemo in maintenance. And T-DXd, as we all expected, in combination with pertuzumab was superior to THP in terms of progression-free survival, really remarkably improved. And you could stop the chemo with toxicity, but most people continued it with T-DXd. Again, not a lot of people got hormone therapy, which is an issue, and you stop the chemo in the control arm. So, this has brought up a lot of interest in trying to use T-DXd as an induction and then go to maintenance, much as we do with the CLEOPATRA regimen with hormone therapy. But it brings up another issue. So first, T-DXd is superior; it's a great treatment. Not everybody needs to have it because we don't know whether it's better to give T-DXd first or second with progression - that we need a little bit longer follow-up. But just earlier this week, interestingly, the third week of December, the U.S. FDA approved T-DXd in the DESTINY-Breast09 approach with pertuzumab. So as I mentioned earlier, there was a T-DXd-alone arm; that arm has not yet reported. So very interesting, we don't know if you need pertuzumab or not. So what about the maintenance? That's the other area where we've made a huge advance here. So, we all want to stop chemo and we want to stop T-DXd. You don't want somebody being nauseated for two years while they're on treatment, and also there's a small number of patients with mostly de novo metastatic HER2-positive disease who are cured of their disease. We'd like to expand that, and I think these new drugs give us the opportunity to improve the number of patients who might be cured from metastatic disease. So the first maintenance study we saw was adding palbociclib, the CDK4/6 inhibitor, to endocrine therapy and HP, essentially. There, we had a remarkable improvement in progression-free survival difference of 15.2 months: 29 to 44 months, really huge. At San Antonio this year, we saw data with this oral tyrosine kinase inhibitor tucatinib, already showed it was great in a triplet, but as maintenance in combination with HP, it showed also a remarkable improvement in progression-free survival. But the numbers were all shifted down. So in PATINA, the control arm was in the 24-month range; here it was the tucatinib-HP arm that was in the 25 months and 16 months for control. So there was a differential benefit in ER-negative and ER-positive disease. So I think we're all thinking that our ideal approach moving forward would be to give T-DXd to most patients, we see how they do, and treat to best response. And then, stop the T-DXd, start HP, trastuzumab, pertuzumab for ER-negative, with tucatinib for ER-positive with palbociclib. We also have early data that suggests that both approaches may reduce the development of brain metastases, an issue in HER2-positive disease, and delay time to progression of brain metastases as seen in HER2CLIMB-05 in very early data - small numbers, but still quite intriguing that you might delay progression of brain metastases with tucatinib that clearly has efficacy in the brain. So, I think that this is a hugely exciting advance for our patients, and these approaches are quickly moving into the early stage setting. T-DXd compared to standard chemo, essentially followed by THP, so a sequenced approach resulted in more pathologic complete responses than a standard THP-AC-type neoadjuvant therapy. T-DXd alone for eight cycles wasn't better, and that's interesting. We still need the sequenced non-cross-resistant chemo. But I think even more importantly, the data from DESTINY-Breast05 looking at T-DXd versus T-DM1 in patients with residual disease after neoadjuvant HER2-targeted therapy showed a remarkable improvement in invasive disease-free survival with T-DXd versus T-DM1, and quite early. It was a high-risk population, higher risk than the T-DM1 trial with KATHERINE, but earlier readout with a remarkable improvement in outcome. We expect to be FDA approved sometime in the first half of 2026. So then we'll get patients who've already had T-DXd who get metastatic disease. But my hope is that with T-DXd, maybe with tucatinib in the right group of patients or even sequenced in very high-risk disease, that we could cure many more patients with early-stage HER2-positive breast cancer and cure a subset, a greater subset of patients with de novo metastatic disease. Dr. Monty Pal: That's brilliant. And you tackled so many questions that I was going to follow up with there: brain metastases, etc. That was sort of looming in my mind. I mean, general thoughts on an ADC versus a TKI in the context of brain mets? Dr. Hope Rugo: Yeah, it's an interesting question because T-DXd has shown quite good efficacy in this setting. And tucatinib, of course, had a trial where they took patients with new brain mets, s

Therapy for Stage IV NSCLC With Driver Alterations: ASCO Living Guideline Update 2026.3.0 Part 2

Dr. Sonam Puri discusses the full update to the living guideline on stage IV NSCLC with driver alterations. She shares a new overarching recommendation on biomarking testing and explains the new recommendations and the supporting evidence for first-line and subsequent therapies for patients with stage IV NSCLC and driver alterations including EGFR, MET, ROS1, and HER2. Dr. Puri talks about the importance of this guideline and rapidly evolving areas of research that will impact future updates. Read the full living guideline update "Therapy for Stage IV Non-Small Cell Lung Cancer With Driver Alterations: ASCO Living Guideline, Version 2026.3.0" at www.asco.org/thoracic-cancer-guidelines TRANSCRIPT This guideline, clinical tools and resources are available at www.asco.org/thoracic-cancer-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO-25-02822 Brittany Harvey: Hello and welcome to the ASCO Guidelines podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I'm interviewing Dr. Sonam Puri from Moffitt Cancer Center, co-chair on "Therapy for Stage IV Non-Small Cell Lung Cancer with Driver Alterations: ASCO Living Guideline, Version 2026.3.0." It's great to have you here today, Dr. Puri. Dr. Sonam Puri: Thanks, Brittany. Brittany Harvey: And then just before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Puri, who has joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then, to dive into the content that we're here today to talk about, Dr. Puri, this living clinical practice guideline for systemic therapy for patients with stage IV non-small cell lung cancer with driver alterations is updated on an ongoing basis. So, what data prompted this latest update to the recommendations? Dr. Sonam Puri: So Brittany, non-small cell lung cancer is one of the fastest-moving areas in oncology right now, particularly when it comes to targeted therapy for driver alterations. New data are emerging continuously from clinical trials, regulatory approvals, real-world experience, which is exactly why these are living guidelines. The goal is to rapidly integrate important advances as they happen, rather than waiting for years for a traditional update. Since the last full update of the ASCO Stage IV Non-small Cell Lung Cancer Guideline with Driver Alterations published in 2024, there have been seven new regulatory approvals and changes in first-line therapy for some driver alterations. [This version] of the "Stage IV Non-small Cell Lung Cancer Guidelines with Driver Alterations" represents a full update, which means that the panel reviewed and refreshed every applicable section of the guideline to reflect the most current evidence across therapies including sequencing and clinical decision-making. This is to ensure that clinicians have up-to-date practical guidelines that keep pace with how quickly the field is evolving. Brittany Harvey: Absolutely. As you mentioned, this is a very fast-moving space and this full update helps condense all of those versions that the panel reviewed before into one document, along with additional approvals and new trials that you reviewed during this time period. So then, the first aspect of the guideline is there's a new overarching recommendation on biomarker testing. Could you speak a little bit to that updated recommendation? Dr. Sonam Puri: Yeah, definitely. So the panel has discussed and provided recommendations on comprehensive biomarker testing and its importance in all patients diagnosed with non-small cell lung cancer. Ideally, biomarker testing should include a broad-based next-generation sequencing panel, rather than single-gene tests, along with immunohistochemistry for important markers such as PD-L1, HER2, and MET. These results really drive treatment decisions, both in frontline settings for all patients diagnosed with non-small cell lung cancer and in subsequent line settings for patients with non-small cell lung cancer harboring certain targetable alterations. Specifically in the frontline setting, it helps determine whether a patient should receive upfront targeted therapy or immunotherapy-based approach. We now have strong data that shows that complete molecular profiling results before starting first-line therapy is associated with better overall survival and actually more cost-effective care. Using both tissue and blood-based testing can improve likelihood of getting actionable results in a timely way, and we've also provided guidance on platforms that include RNA sequencing, which are specifically helpful for identifying gene fusions that might be otherwise missed with other platforms. On the flip side, outside of a truly resource-limited setting, single-gene PCR testing really should not be routine anymore. This is what the panel recommends. It's less sensitive and inefficient and increases the risk of missing important actionable alterations. Brittany Harvey: Understood. I appreciate you reviewing that recommendation. It really helps identify critical individual factors to match the best treatment option to each individual patient. So then, following that recommendation, what are the updated recommendations on first-line therapy for patients with stage IV non-small cell lung cancer with a driver alteration? Dr. Sonam Puri: Since the last full update in 2024, there have been four additional interim updates which were published across 2024 and 2025. Compared to the last version, there have been several updates which have been included in this full update. One of the most important shifts has been in first-line treatment of patients with non-small cell lung cancer harboring the classical, or what we call as typical, EGFR mutation. The current version of the recommendation is based on the updated survival data from the phase III FLAURA2 and MARIPOSA studies, based on which the panel recommended to offer either osimertinib combined with platinum-pemetrexed chemotherapy or the combination of amivantamab plus lazertinib in the first-line treatment of classical EGFR mutations. And these recommendations, as I mentioned, are grounded in the results of the FLAURA2 and MARIPOSA trials, both of which demonstrated improvement in progression-free survival and overall survival compared to osimertinib alone in patients with common EGFR mutations. That being said, the panel actually spent significant time discussing the toxicities associated with these treatments as well. These combination approaches come with higher toxicity, longer infusion time, increased treatment frequency. So while combination therapy is now recommended as preferred, the panel has recommended that osimertinib monotherapy remains a reasonable option, particularly for patients with poor performance status and for those who are not interested in treatment intensification after knowing the risks and benefits. Brittany Harvey: Absolutely. It's important to consider both those benefits and risks of those adverse events that you mentioned to match appropriately individualized patient care. So then, beyond those recommendations for first-line therapy, what is new for second-line and subsequent therapies? Dr. Sonam Puri: So this is a section that saw several major updates, particularly again in the EGFR space. The first was an update on treatment after progression on osimertinib for patients with classical EGFR mutation. Here the panel recommends the combination of amivantamab plus chemotherapy, and this recommendation was based on the phase III MARIPOSA-2 trial, which compared amivantamab plus chemotherapy with chemotherapy alone with progression-free survival as the primary endpoint. The study met its primary endpoint, showing an improvement in median PFS with the combination of amivantamab plus chemotherapy compared to chemotherapy alone. And as expected, the combination was associated with higher toxicity. So, although the panel recommends this regimen, the panel emphasizes that patients should be counseled on the side effects which may be moderate to severe with the combination therapy approach. In addition, a new recommendation was added for patients who are not candidates for amivantamab plus chemotherapy. In those cases, platinum-based chemotherapy with or without continuation of osimertinib may be offered, and the option of continuing osimertinib with chemotherapy was recommended and supported by data from a recently presented phase III COMPEL study, which randomized 98 patients with EGFR exon 19 deletion or L858R-mutated advanced non-small cell lung cancer who had experienced no CNS progression on first-line osimertinib, and these patients were randomized to receive platinum-pemetrexed chemotherapy with osimertinib or placebo. Although this study was small, it demonstrated a PFS benefit with continuation of osimertinib with chemotherapy, and this approach may be appropriate for patients without CNS progression who prefer or require alternatives to more intensive treatment strategies. Next was an update on options for patients with EGFR-mutated lung cancer after progression on osimertinib and platinum-based chemotherapy. Here the panel recommended that for patients whose disease has progressed after both osimertinib and platinum-based chemotherapy, a new drug known as datopotamab deruxtecan can be offered as a treatment opt

Smell: The Scent of Inevitability

Listen to JCO's Art of Oncology article, "Smell," by Dr. Alice Cusick, who is a Hematology Section Chief at Veterans Affairs Ann Arbor Health System and Assistant Professor at the University of Michigan Division of Hematology and Oncology. The article is followed by an interview with Cusick and host Dr. Mikkael Sekeres. Dr Cusick shares a connection to a cancer patient manifested as a scent. TRANSCRIPT Narrator: Smell, by Alice Cusick, MD Dr. Mikkael Sekeres: Welcome back to JCO's Cancer Stories: The Art of Oncology. This ASCO podcast features intimate narratives and perspectives from authors exploring their experiences in oncology. I'm your host, Mikkael Sekeres. I'm Professor of Medicine and Chief of the Division of Hematology at the Sylvester Comprehensive Cancer Center, University of Miami. Joining us today is Alice Cusick, Hematology Section Chief at the Veterans Affairs Ann Arbor Healthcare System and Assistant Professor at the University of Michigan, Division of Hematology and Oncology, to discuss her Journal of Clinical Oncology article, "Smell." Alice, thank you for contributing to Journal of Clinical Oncology and for joining us to discuss your article. Dr. Alice Cusick: Thank you so much for having me, Mikkael. I appreciate it. Dr. Mikkael Sekeres: It's really a pleasure, and as usual, Alice and I discussed this beforehand and agreed to call each other by first names. I always love to hear your story first. Can you tell us about yourself? Where are you from, and walk us through your career, if you could. Dr. Alice Cusick: I'm a Midwesterner. I grew up in Iowa and Illinois and went to a small college in Illinois, played basketball, Division lll, and was an English Literature major. I took one science class and was going to be an English professor. And then my father's a physician. My senior year, I realized I don't think I could spend all my time in a library. I didn't feel like I was helping anyone. And so I talked to my dad, and he said, "Yeah, I think you could be a doctor." So I thought I would help people by being a physician. So I moved to Iowa City and spent two years working in a lab and doing science classes and took the MCAT, which was the first year they had the essay on there, and I rocked that. That was my highest score. I got into the University of Iowa and then went on to residency and fellowship at the University of Wisconsin, just in hematology. I didn't do solid tumors. And then went on, spent a couple years there, worked in Pennsylvania in more of a group practice, and then came back to academics at the University of Michigan about 10 years ago. And then five years ago, I became the Hematology Section Chief at the VA in Ann Arbor. So I work there full time now. Dr. Mikkael Sekeres: I love that story. I served on the admissions committee at Cleveland Clinic and Case Western when I was also a Midwesterner for 18 years. And I always wondered if instead of searching for science majors, we should be searching for English majors because I think there's a core element of medicine that is actually storytelling. Dr. Alice Cusick: Oh, very much so. My father was a country doctor for many, many years in rural Iowa in the fifties and sixties. So he did house calls, and he talked about how you really got to know people by going to their house. And I'll never forget the first time that I did a full history and physical, I think I was maybe a second-year medical student, and I was telling him, "Oh, I'm so excited. I'm going to do my first history and physical." And he said, "Alice, don't talk to them about medicine right away or about their problems right away. Talk to them about something else. Get to know them because you know about sports, talk about sports." I said, "Dad, that's called establishing rapport." You know, that's what they had taught us. But it was intuitive to him. I'll never forget that he just said their story is important and how they live and where they live and who they live with is so important. It really helps you figure out their medical issues as well. And I've always tried to carry that through. Dr. Mikkael Sekeres: It's funny what we glean from our parents. My dad was a journalist for the Providence Journal-Bulletin. He was a reporter for a couple of decades, and I almost feel like some of what I'm doing is acting as a reporter. It's my job to get the story and get the story right and solicit enough details from a patient that I really have a sense that I'm with them on the journey of their illness, so I can understand it completely. Dr. Alice Cusick: Oh, very much so. And that's one of the things I really harp about with the fellows because sometimes I remember more of the social history than I do sometimes the medical history when I'm seeing a patient. I remind them, you need to know who they live with and how they live. It helps you take care of them. Dr. Mikkael Sekeres: Well, and that must be particularly germane with your patient population. When I was a medical student, my first rotation on internal medicine was at the Philadelphia VA, and it's actually what convinced me to specialize within internal medicine. What is it like caring for veterans? Dr. Alice Cusick: This is the best job I've ever had in my life. And I think because it speaks to my sense of duty that I got from my parents, particularly from my father, and I really feel I got back to my original focus, which is helping people. So that sense of duty and serving those who served, which is our core mission, this job is the most rewarding I've ever had because you really feel like you're helping people. Dr. Mikkael Sekeres: How much do you learn about your patients' military history when you first interact with them? Dr. Alice Cusick: It can come up in conversation. It sort of depends on what the context is and how much you ask and how much of that is incorporated into what's going on with their medical history. It comes up a lot in terms of, particularly cancer, because a lot of cancers that veterans develop can be related to their military exposures. So it can come up certainly in that context. Dr. Mikkael Sekeres: You write about how your patient and his wife brought in photographs of his younger self. Can you describe some of those photos? Dr. Alice Cusick: So a lot of it was about the sports he was doing at the time. He was kind of almost like a bodybuilder and doing like martial arts. So there were some pictures of him in his shirt and shorts, showing how healthy he was. He was much younger, but it was such a contrast to how he was at that time as he was nearing death. But it really rounded out my understanding of him because, as we all know, when we meet people, we see them when they're at that particular age, and we may not have that context of what they were 20, 30 years ago. But that still informs how they think about themselves. I mean, I still think of myself as an athlete even though I'm much older. So that's important to understand how the patient thinks about himself or herself. Dr. Mikkael Sekeres: You know, it's funny you mentioned those two photographs. I- immediately flashed into my mind, I had a patient who also was a martial arts expert, and I remember he was in his early seventies and hospitalized, but he made sure to put up that photo of him when he was in his prime, in his martial arts outfit in a pose. And I've had another patient who was a boxer, and all he wanted to talk about whenever he saw me was his first experience boxing in Madison Square Garden and what that moment felt like of climbing into the ring, squeezing in between the ropes, and facing off in front of what must have been some massive crowd. Dr. Alice Cusick: Yeah. Dr. Mikkael Sekeres: Why do you think it was important to them to bring in those photos to show you? Dr. Alice Cusick: I think it was to help me understand what he had been. I think it was important for him, and because we had a relationship, it wasn't just transactional in terms of his medical problems. It was really conversations every day about what he was doing and how his life was going. And I think he really wanted me to understand what he had been. And so I felt really honored because I think that was important. It told me that his relationship with me was very important to him. I found that very, very humbling. Dr. Mikkael Sekeres: Yeah, I find it fascinating the details that patients offer to us about themselves as opposed to the ones that we solicit. I think it speaks to also the closeness of the relationship we have with patients when they want to share that aspect of them. They want to show you who they were before they were ill. And it's not a point of bragging. It's not flexing for them. I think it's really to remind themselves and us of the vitality of the person who's sitting in front of us or lying in front of us in the hospital johnny or sitting on an exam table. Dr. Alice Cusick: Oh, very much so. And I've experienced that even with my own parents as they got older and were in the medical system. I remember vividly, my father had had a stroke, and the people taking care of him didn't understand what he had been. They didn't understand that his voice was very different. We kept asking, you know, "His voice is different." They had no concept of him beforehand. So that also really hit home to me how important it is to understand patients in the whole context of their lives. Dr. Mikkael Sekeres: And as a family member, do you think it's equally important to share that story of who somebody was before they were ill as a reminder to yourself and to the people taking care of a relative? Dr. Alice Cusick: Oh, very much so. I think it's very helpful because it also makes you feel like you're supporting the loved one as well by, if they can't speak for themselves, particularly when they're very ill, to help people understand, it may help the physicians or any p

Management of Cancer During Pregnancy Guideline

Dr. Alison Loren and Dr. Ann Partridge share the latest guideline from ASCO on the management of cancer during pregnancy. They highlight the importance of this multidisciplinary, evidence-based guideline and overarching principles for the management of cancer during pregnancy. Drs. Loren and Partridge discuss key recommendations from each section of the guideline, including diagnostic evaluation, oncologic management, obstetrical management, and psychological and social support. They also touch on the importance of this guideline and accompanying tools for clinicians and how this serves as a framework for pregnant patients with cancer. The conversation wraps up with a discussion on the unanswered questions and how future evidence will inform guideline updates. Read the full guideline, "Management of Cancer During Pregnancy: ASCO Guideline" at www.asco.org/survivorship-guidelines TRANSCRIPT This guideline, clinical tools, and resources are available at www.asco.org/survivorship-guidelines. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in the Journal of Clinical Oncology, https://ascopubs.org/doi/10.1200/JCO-25-02115  Brittany Harvey: Hello and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey, and today I am interviewing Dr. Alison Loren from the Perelman School of Medicine of the University of Pennsylvania and Dr. Ann Partridge from Dana-Farber Cancer Institute, co-chairs on "Management of Cancer During Pregnancy: ASCO Guideline." Thank you for being here today, Dr. Loren and Dr. Partridge. Dr. Alison Loren: Thanks for having us. Dr. Ann Partridge: It's a pleasure. Brittany Harvey: And then just before we discuss this guideline, I would like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO conflict of interest policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Partridge and Dr. Loren who have joined us here today, are available online with the publication of the guideline in the Journal of Clinical Oncology, which is linked in the show notes. So then to dive into the meat of this guideline, to start us off, Dr. Loren, could you provide an overview of the scope and purpose of this new guideline on the optimal management of cancer during pregnancy? Dr. Alison Loren: Sure, thanks, Brittany. So this was really born out of I think a lot of passion and concern for this really vulnerable patient population. We have observed, and I am sure it is not any surprise to your audience, that the incidence of cancer in young people is increasing. And simultaneously, people are choosing to become pregnant at older ages, and so we are seeing more and more people with a cancer diagnosis during their pregnancy. And for probably obvious reasons, there is really no way to do randomized clinical trials in this population. And so really trying to assemble and articulate the best evidence for safely managing the diagnosis of cancer, the management of cancer once it is confirmed, being thoughtful about obviously the health of the mom, but also attending to potential risks to the developing fetus, and really just trying to be really comprehensive and balanced about all the choices for these patients when they are facing some really challenging decisions in a very emotionally fraught environment. And I think it is really emotionally fraught for the providers, too. You know, this is obviously an extremely intense, very emotional set of decisions, and so trying to provide a rudder essentially to sort of help people frame the questions and trying to make as evidence-based a set of recommendations as possible. Dr. Ann Partridge: And I would just add that "evidence-based" is a strong word here because typically our, as you just heard, our gold standard evidence is a randomized trial, but you can't do that in this setting, in general. And so, what we were able to do with the support of the phenomenal ASCO staff was to pull together kind of the world's literature on the safety and outcomes of treatments during pregnancy, as well as consensus opinion. And I think that is a really, really critical difference about this particular guideline compared to many of the other ones that ASCO does, where consensus and good judgment needed to kind of rule the day when evidence is not available. So, there is a lot of that in our recommendations. Dr. Alison Loren: That is such a good point. And I just, before we move forward, I just want to reflect that the composition of the panel was really broad and wide-ranging. We had maternal medicine specialists, we had legal and ethical experts, we had representatives who understand pharmaceutical industries' perspectives, and then medical oncologists representing the full spectrum of oncology diagnoses. And so it was a really diverse, in terms of expertise, panel, internationally composed to try to really get the best consensus that we could in the absence of gold standard evidence. Brittany Harvey: Absolutely. That multidisciplinary panel is really key to developing this guideline and, as you said, looking at the evidence and even though it does not reach the level of randomized trials, still critically evaluating it and reviewing that along with consensus to come up with optimal management for diagnosis and management of cancer during pregnancy. So then to follow that up, I would like to next review the key recommendations of the guideline across the main sections that the expert panel provided. First, I will throw this out to either of you, but what are the important general principles for the management of cancer during pregnancy? Dr. Ann Partridge: I think there were three major principles that we hammer home in the guidelines. One is that this is a team sport. It is multidisciplinary care that is necessary in order to optimize outcomes for the patient and potentially for the fetus. And that you really need to, from the beginning, bring in a coordinated team, including not just oncologists but obstetricians, maternal-fetal medicine specialists, neonatologists, ethics consultants, and obviously the patient and potentially her family. So that, I think, is one of the most important things. Second would be that obviously in a pregnancy, there are two potential patients and that the nuances of safety and risk from treatment is really wrapped up in where in the trimester of the pregnancy the patient is diagnosed, along with the kind of cancer that it is, both the urgency of treatment and the risk of the cancer, as well as the potential risks of any given intervention across the cancer continuum. It is a broad guideline in that regard. And then finally, and this is particularly timely given what is going on from a sociopolitical standpoint in the U.S., really thinking about informed consent and potential ethical as well as legal implications of some of the choices that patients might have when they are thinking about, in particular, continuing a pregnancy or potential termination. Dr. Alison Loren: And I will just add that I think that the key to all of this guidance is nuance and individualization and also making sure that patients and their care providers understand all the choices that are available to them and also the consequences of those choices. You know, nobody would choose to receive chemotherapy during pregnancy if that wasn't necessary. So there are risks to treatment, but there are also risks to not treatment. And making sure that in a suboptimal situation where you do not have a lot of evidence, trying to weigh, the best you can, the risks and benefits of all of the choices so that the patient can come to a decision about the treatment plan that is right for her. Brittany Harvey: Definitely. And those core concepts really set the stage for individualized care on what is necessary for appropriate multidisciplinary care, prioritizing both patient autonomy and informed decision making. With those core concepts and key principles in mind, I would like to move into the recommendations section of the guideline. So what are the key recommendations regarding diagnostic evaluation for pregnant patients with signs or symptoms of cancer? Dr. Alison Loren: I think the most important thing is to not delay, that there are very careful and well-thought-out recommendations for how to evaluate a potential cancer. And while there are certain things that we know can be harmful, particularly when certain dose thresholds are exceeded - for instance, abdominal imaging, there are certain radiographic thresholds that you don't want to exceed because of risk of harm to the embryo or fetus - there are still lots of options for diagnosing cancer during pregnancy. And again, thinking about the costs of not doing versus the cost of doing, right? It is really important to make the diagnosis of cancer if that is a consideration or a concern. And sometimes going directly to biopsies or getting definitive studies, even if there is a small risk to the developing fetus, is really essential because if the mom does not survive, of course, the fetus is also not going to survive. And so we need to be thinking first about the patient who is sitting in front of us, the woman who needs to know what is going on in her body so she can make good decisions about her health. So, I think that is a key principle in thinking about this. Brittany Harvey: Absolutely. So, following that diagnosis of a new or recurrent cancer, what is recommended for oncologic management of patients who are diagnosed with cancer during their pregnancy? Dr. Ann Partridge: So, I think the general prin

Genomic Profile of Small Cell Bladder, Lung and Urothelial Cancer

JCO PO authors Dr. Abhishek Tripathi and Dr. Salvador Jaime-Casas at City of Hope Comprehensive Cancer Center share insights into their article, "Comparative Genomic Characterization of Small Cell Carcinoma of the Bladder Compared With Urothelial Carcinoma and Small Cell Lung Carcinoma." Host Dr. Rafeh Naqash and Drs. Tripathi and Jaime-Casas discuss a novel understanding of the genomic alterations underlying SCBC, revealing actionable mutations that could serve as potential targets for improved clinical outcomes. TRANSCRIPT Dr. Rafeh Naqash: Hello and welcome to JCO Precision Oncology Conversations, where we bring you engaging conversations with authors of clinically relevant and highly significant JCO PO articles. I am your host, Dr. Dr. Rafeh Naqash, Podcast Editor for JCO Precision Oncology and Associate Professor at the OU Health Stephenson Cancer Center at the University of Oklahoma. Today, I am thrilled to be joined by Dr. Abhishek Tripathi, Associate Professor in the Department of Medical Oncology and Experimental Therapeutics Research at the City of Hope Comprehensive Cancer Center, as well as his mentee, Dr. Salvador Jaime-Casas, postdoctoral research fellow and first author of the JCO Precision Oncology article entitled "Comparative Genomic Characterization of Small Cell Carcinoma of the Bladder Compared with Urothelial Carcinoma and Small Cell Lung Carcinoma". At the time of this recording, our guest disclosures will be linked in the transcript. Abhishek and Salvador, welcome to our podcast and thank you for joining us today. This is a very interesting topic given that at least the landscape for neuroendocrine carcinomas, where small cell lung cancer is on one end of the spectrum, has been changing, at least on the lung cancer side, with recent approvals and some new ADCs. So, of course, understanding the genomic and transcriptomic similarities or differences between pulmonary small cell and extrapulmonary small cell is of huge interest. Could you tell us a little bit about small cell bladder cancer, current approaches to treatment of small cell bladder cancer, and then why you wanted to investigate that in this project as far as the genomic differences or similarities are concerned? Dr. Salvador Jaime-Casas: Well, first of all, thank you very much for having me. I am very excited to be here. And really what served as backbone for this research project was the notion that there is a currently evolving genomic landscape in the area of bladder cancer. We know this is a highly heterogeneous disease when it comes to molecular underpinnings and mutational profile. Specifically, we know that the most common histologic subtype is urothelial carcinoma. Small cell bladder cancer represents a histology that is found in less than 1% of all bladder cancer cases. However, it is one of the most aggressive histologies. It presents with a very poor prognosis to patients and very poor response to treatment, which is why we attempted to really elucidate what is the mutational profile behind this and provide a comparison contrast between small cell bladder cancer, small cell lung cancer, and conventional urothelial carcinoma. As your question mentioned, in terms of treatment, the conventional urothelial carcinoma and small cell bladder cancer are two distinct pathways when it comes to treatment algorithms. We know that in the current era there are newer and newer drugs being developed for conventional urothelial carcinoma. We have perioperative immunotherapy in the context of metastatic disease. We have antibody-drug conjugates such as enfortumab vedotin. But really, this amazing track record of drug development hasn't been mirrored in small cell bladder cancer. And here most of the therapy is usually extrapolated from studies from other small cell histologies like you mentioned earlier, small cell lung cancer has given some form of background in terms of what therapies are used here. Cytotoxic chemotherapy, for some patients with localized disease and small cell bladder cancer, concurrent chemotherapy and radiotherapy or perioperative cytotoxic chemotherapy have been the cornerstone of treatment for many years now. However, like I mentioned, the oncologic outcomes are very suboptimal when it comes to comparing it with other disease histologies, which is why we really wanted to describe the landscape here and provide this comparison across three different groups. For this particular study, we leveraged the Tempus dataset. So, include patients with urothelial carcinoma with small cell bladder cancer and small cell lung cancer. We included their demographic information, as well as the frequency of most common genomic alterations identified. And really, it was a very comparable Table 1. We see the demographic data across the three groups was very similar. One key thing that we identified was the female prevalence was a little bit lower in patients with small cell bladder cancer when compared to small cell lung cancer. But other than that, the age, race, ethnicity, was comparable across groups, and even the smoking history. Most of the patients in this cohort were former smokers, which we believe comes to explain that regardless of any mutational profile that we talked about in a few minutes, there are shared commonalities between these histologies and shared environmental exposures and risk factors that are going to be implicated in the disease biology for these three histologies. Dr. Rafeh Naqash: Thank you so much, Salvador, for that useful background. I would like to shift to Abhishek real quick. Abhishek, you are a practicing clinician, you have led several studies in the GU space, especially bladder. Based on what you see in the small cell lung cancer space, how drug development is shaping up, which aligns with what you are trying to evaluate in this paper as targets, how do you see some of that being implemented for small cell bladder cancer in the current era and age? Abhishek Tripathi: Thanks so much for the excellent question, Rafeh. As a GU investigator, small cell bladder cancer has always lagged behind in some regards regarding enrollment abilities for the novel clinical trials. And small cell lung cancer has paved the way and led the development of a lot of these drugs across the board. With the most recent sort of drugs targeting DLL3 already approved and several antibody-drug conjugates currently in development. That actually translates really well to how we should approach drug development in bladder cancer. What we saw in the study is that although there are overlaps and similarities between small cell lung cancer and small cell bladder cancer, there are also certain differences. So the long-term assumption that all therapies for small cell bladder cancer can be extrapolated to small cell bladder], may or may not be true, and I think it is high time that we specifically investigate these novel agents in tissue-specific small cell carcinomas. To that effect, we are excited to be participating in trials that are looking at some of the novel DLL3 targeted agents, specifically bispecific antibodies and T cell engagers so to speak, and antibody-drug conjugates that are now starting to open enrollment specifically in non-lung cancer cohorts to evaluate its efficacy. So overall, I think studies like this have the opportunity to identify more putative targets for organ-specific development of these novel agents. Dr. Rafeh Naqash: Absolutely, I could not agree more. I think tumor-agnostic therapies definitely have a place, but not all therapies work the same in different tumors with a similar histological or genomic background because there are definitely differences. So now going to the comparison that Salvador, you guys did in this project, could you help us understand what are some of the things you looked at, what were some of the commonalities and the differences, and what were some of the conceptual thoughts that come out from those results? Dr. Salvador Jaime-Casas: Of course. So, the first thing that we identified was which were the most frequent molecular alterations across these histologies. We actually provided a table showcasing how the most common mutations that we identified were TP53, TERT, RB1. However, like Dr. Tripathi mentioned, the distinction between these histologies is notable in the sense that some are more predominant in small cell-pertaining cancers such as bladder cancer and lung cancer. While some others are more common in bladder-pertaining malignancies like urothelial carcinoma and small cell bladder cancer. For instance, we saw that TP53 and RB1 were significantly more evident in small cell histologies, both small cell bladder cancer and small cell lung cancer, as opposed to conventional urothelial carcinoma, which really this mirrors what is known about these mutations and what has been published. These are markers associated with more aggressive disease with a worse prognosis and even to resistance to treatment. We also identified how TERT mutations were characteristically more prevalent in small cell bladder cancer as opposed to small cell lung cancer, as well as in urothelial carcinoma. TERT mutations were more commonly identified than in small cell lung cancer. And we give a long list of these mutations that we identified, but really what we wanted to underscore here was, A, the most common mutations across histologies; B, the most common co-occurring mutations where we saw that these are not mutually exclusive. A lot of patients had co-occurring TP53 and RB1 or RB1 and TERT or RB1 and ARID1A, really elucidating how heterogeneous this molecular landscape is across histologies. And the third one that we believe really brings down the clinical impact of this research was evidencing the idea of clinically actionable mutations. We also provided a table here showcasing how mutations like FGFR, DLL notch pathway, HER2, were evident in th

TTFields in Locally Advanced Pancreatic Adenocarcinoma

Host Dr. Shannon Westin and guest Dr. Hani Babiker discuss the JCO article "Tumor Treating Fields With Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: Randomized, Open-Label, Pivotal Phase III PANOVA-3 Study." TRANSCRIPT TTFields in Locally Advanced Pancreatic Adenocarcinoma Dr. Shannon Westin: Hello everyone, and welcome to another episode of JCO After Hours, the podcast where we get in depth with manuscripts that have been published in the Journal of Clinical Oncology. I am your host, gynecologic oncologist Shannon Westin, social media editor at the JCO, and just excited to be here to learn today about pancreatic cancer. None of our participants have conflicts of interest related to this podcast, and it is my honor to introduce Dr. Hani Babiker. He is an associate professor of medicine, consultant in oncology at the Mayo Clinic in Jacksonville, Florida. Welcome, Dr. Babiker. Dr. Hani Babiker: Hi, Dr. Westin. Thank you for the great opportunity to discuss our trial, and thank you for having me here. I really appreciate it, and I am excited. Dr. Shannon Westin: All right, so are we. So we are going to be talking about "Tumor Treating Fields with Gemcitabine and Nab-Paclitaxel for Locally Advanced Pancreatic Adenocarcinoma: A Randomized, Open-Label, Pivotal Phase III PANOVA-3 Study." This was simultaneously published and presented in the JCO and at the annual meeting of ASCO on 5/31/2025. So, let's level set. Can you speak to us just a little bit about pancreatic cancer? What is the survival, and what is the typical treatment for locally advanced disease? This gynecologic oncologist has not kept up in this field. Dr. Hani Babiker: Absolutely, Dr. Westin, and thank you for that question. Pancreatic adenocarcinoma is a lethal cancer. When I first started my career, the 5-year survival, per the Surveillance, Epidemiology, and End Results, was at 4.5%. I always, whenever I was giving talks, say that I really hope that I will see it in the double digit. Now, the 5-year survival for all pancreatic adenocarcinoma is 13.3%. And the 5-year survival, and although it is a double digit, I still hope that I will see it in a higher double digit in the future. It is even worse in patients with metastatic cancer, about 3% 5-year survival for metastatic pancreatic cancer. It is a dismal diagnosis. I really hope in the future we will find a better therapeutic approach to this lethal cancer. Dr. Shannon Westin: Yes, I just lost a very dear friend and colleague to this disease, so I completely agree with you. Well, now that we are settled kind of with the basics here, I would love to talk a little bit about kind of the primary piece of this intervention, the Tumor Treating Fields. So, how does this work? And what diseases has it gotten indications in as yet? Dr. Hani Babiker: Absolutely. So, Tumor Treating Fields is alternating frequency electrical fields that have been studied preclinically and shown that it abrogates cancer cell proliferation. Earlier on, we knew that it inhibits polymerization of tubulin, and hence, it affects cancer cells from proliferating. Later, we are learning that there are multiple mechanisms of action. It affects permeability, allowing for better drug delivery. It also inhibits cancer cell proliferation through affecting autophagy mechanisms that pancreatic cancer cells will use for proliferating and becoming more aggressive. There is also some early data preclinically in colorectal cancer cell lines and lung cancer cell lines and in vivo models showing that it potentially could activate the microenvironment to make it more pro-immunogenic. We recently published papers showing that it could also affect the nanomechanical properties of the tumor microenvironment within pancreatic cancer, hinting towards affecting, potentially, the stroma. So, there are multiple mechanisms to Tumor Treating Electric Fields. It is a new, novel therapeutic approach. Sometimes when I speak with my trainees, I say, "Well, we have surgery, we have radiation and chemotherapy, and this is something new." Tumor Treating Fields initially was studied in refractory GBM and got an indication there. Subsequently, frontline treatment of GBM in a randomized clinical trial, and then malignant pleural mesothelioma and non-small cell lung cancer. We have studied it in pancreatic cancer. Dr. Shannon Westin: I don't think I have ever heard it described so perfectly. That was brilliant. So thank you, and I hope everyone listening knows that you just got a masterclass on this mechanism. You know, they dabbled in it a little bit in ovarian cancer and it didn't quite make the grade, so I was a little definitely disappointed. But very excited about the data we're going to talk about today. So let's get into the PANOVA-3 study. Can you highlight the overall design and also the key eligibility criteria that would be helpful for our listeners? Dr. Hani Babiker: Absolutely. So, it started off with preclinical work in pancreatic cancer showing Tumor Treating Fields with chemo abrogate cancer cell perforation. It led to a trial, the PANOVA-2 trial, that was run in Europe that showed efficacy for OS and PFS in patients with locally advanced pancreatic cancer, which included metastatic and locally advanced pancreatic cancer, more so in locally advanced that led to the PANOVA-3 trial, which was an international, global study. This was in more than 190 centers, 20 countries in Latin America, North America, Europe, and Asia. It was a randomized trial. Patients were randomized 1 to 1 to either chemotherapy with gemcitabine plus nab-paclitaxel per drug label. The other arm was with Tumor Treating Fields at 150 kHz for a recommendation for patients to wear it 18 hours per day. The primary end point of the trial was OS, overall survival. The secondary end point included other efficacy landmarks such as local PFS, pain control, quality of life, and safety. And there was a post hoc that looked at distant PFS. Dr. Shannon Westin: That's a pretty common secondary end point in pancreatic studies of looking at the pain-free interval. I thought that was really brilliant because, you know, I think in gyn cancers, we see resolution of symptoms as being a really big deal, but it's not necessarily something that we always look at. So I thought that was really nice that you included that. Okay, talk to us a little bit about the population. So, the population that actually got treated in PANOVA-3 is pretty generalizable to what people are treating in the clinic. Dr. Hani Babiker: So, in pancreatic cancer, unfortunately, most of our patients present, approximately 80%, with metastatic disease. Local is divided to resectable, borderline, and locally advanced. We studied this trial, a randomized trial, in locally advanced and unresectable, which is really an unmet need. Most of our patients with locally advanced and unresectable are grouped up with other trials in the metastatic setting without a focus on locally advanced and unresectable, save for a few trials. This year, a trial that we were looking for for a long time, the LAPLACE trial, unfortunately, that we were very excited about, this is a molecule that targeted connective tissue growth factor, that showed earlier efficacy in a randomized trial, did not meet up the median OS end point. And hence, PANOVA-3 is the first trial in locally advanced and unresectable that did meet its primary end point. So, it's a very unmet need in locally advanced and unresectable. A lot of the times, our patients in clinic are treated with frontline chemotherapy that was studied in metastatic disease and locally advanced and unresectable, which include either FOLFIRINOX, NALIRIFOX, or gemcitabine/abraxane. I do have in my clinic multiple patients that would stay on the regimen for such a long time, and then we would have to devise a mechanism of maintenance, although this is not studied really in details, either with capecitabine or dropping the oxaliplatin to continue FOLFIRI. And then we also approach chemoradiotherapy. So the trial was in a disease in pancreatic cancer that really is an unmet need. So the inclusion criteria included a patient with locally advanced and unresectable. These were done at multiple centers. Most of them academic centers were discussed at the tumor board, and if it's unresectable, they will be meeting specific metrics of appropriate liver function tests, kidney function tests, and blood counts. We excluded patients that obviously had, given that these are electric fields, patients that have, for example, stimulators or pacemakers, knowing that this could potentially affect some of these devices. But for the most part, it was locally advanced and unresectable patients with a very good performance status and good counts. Dr. Shannon Westin: That's great. I think everyone's excited to hear about the primary outcome of overall survival. What did you find, and how does it compare to some of the recent trials? Dr. Hani Babiker: We're very excited that it did meet its primary end point of median overall survival. It was very exciting knowing that a lot of us were disappointed a little bit of some of the trials that were presented at ASCO GI, such as the LAPLACE trial that I alluded to. Just before the presentation, the PRODIGE 29 trial that is in locally advanced and unresectable that randomized patients with locally advanced disease to either FOLFIRINOX or single-agent gemcitabine, allowing for a crossover, although it did meet its primary end point of PFS, there was no overall survival benefit. So that kind of got us a little bit disappointed, but having the PANOVA-3 trial being positive in median OS got us all excited. In addition, the 12-year overall survival rate was increased in both the intention-to-treat and modified intention-to-treat. The modified intention-to-treat were patients that have had at least one cycle of the

Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors Guideline

Dr. Kimberly Perez and Dr. Jaydira Del Rivero discuss the new guideline from ASCO on symptom management for well-differentiated GEP-NETs. They share the latest recommendations on managing symptoms related to hormone excess, including carcinoid syndrome and carcinoid heart disease, managing symptoms of functioning pancreatic neuroendocrine tumors, and also palliative interventions. Dr. Perez and Del Rivero share how to use this guideline in concert with the systemic therapy for tumor control in metastatic well-differentiated GEP-NETs guideline, and hope for the future for the treatment of gastroenteropancreatic neuroendocrine tumors. Read the full guideline, "Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline." Transcript This guideline, clinical tools, and resources are available on ASCO.org. Read the full text of the guideline and review authors' disclosures of potential conflicts of interest in JCO Oncology Practice. Brittany Harvey: Hello and welcome to the ASCO Guidelines Podcast, one of ASCO's podcasts delivering timely information to keep you up to date on the latest changes, challenges, and advances in oncology. You can find all the shows, including this one, at asco.org/podcasts. My name is Brittany Harvey and today I'm interviewing Dr. Kim Perez from Dana-Farber Cancer Institute and Dr. Jaydira Del Rivero from the Center for Cancer Research at the National Cancer Institute, co-chairs on "Symptom Management for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors: ASCO Guideline." Thank you for being here today, Dr. Del Rivero and Dr. Perez. Dr. Kim Perez: Thank you. Dr. Jaydira Del Rivero: Thank you so much for the invitation. Brittany Harvey: And then before we discuss this guideline, I'd like to note that ASCO takes great care in the development of its guidelines and ensuring that the ASCO Conflict of Interest Policy is followed for each guideline. The disclosures of potential conflicts of interest for the guideline panel, including Dr. Perez and Dr. Del Rivero, who have joined us here today, are available online with the publication of the guideline in JCO Oncology Practice, which is linked in the show notes. So then to jump into the content here, first Dr. Del Rivero, could you provide an overview of the scope and purpose of this guideline? Dr. Jaydira Del Rivero: Yeah. Thank you so much. Well, first, we really wanted to thank ASCO for allowing us to develop these guidelines for the management of gastroenteropancreatic neuroendocrine tumors. I do want to mention that there is also another set of guidelines that I was very fortunate also to co-chair with Dr. Perez on the systemic management of gastroenteropancreatic neuroendocrine tumors. But when discussing these guidelines as well as with the different panelists, experts in this type of disease, we also realized that the management of these tumors are quite complex, not only from the management of the disease progression, but at the same time, management of the symptoms related to the hormone excess. And because of that, we like to thank ASCO for allowing us to then not only have a discussion on the systemic management of these tumors, but at the same time develop recommendations for the symptoms related to the different hormones that these neuroendocrine tumors may produce. These guidelines are for the management of grade 1 to grade 3 metastatic gastroenteropancreatic neuroendocrine tumors. These guidelines include the management of the different aspects and the symptoms related to hormone excess, such as carcinoid syndrome, carcinoid heart disease, how to manage carcinoid crisis, as well as the different symptoms and how to manage the functional pancreatic neuroendocrine tumors and as well as provide recommendations in the different treatments for these tumor types, not only from the systemic management but also from the surgical management as well as for liver-directed therapy options and the different aspects in terms of the palliative care of these patients to improve not only the symptoms related to the hormone excess caused by these tumors, but as well as to improve the quality of life. Brittany Harvey: Absolutely. And I appreciate that overview. And yes, we'll link the guideline on the Systemic Therapy for Tumor Control for Well-Differentiated Gastroenteropancreatic Neuroendocrine Tumors in the show notes for our listeners so that they can refer to that companion guideline as well. So then you just described the several different categories of recommendations that this guideline covers on symptom management. So, Dr. Perez, I'd like to start reviewing some of those key recommendations of that guideline. So, starting with what are the key recommendations for carcinoid syndrome and carcinoid heart disease? Dr. Kim Perez: Thank you Brittany. Yeah, I also want to thank ASCO for inviting us to do this podcast today. Just to start, I think these guidelines will really add to what's available in the literature to provide a kind of a quick look for the community provider to manage carcinoid-related symptoms. I think the highlights that I would point out are we've all been using somatostatin analogs for the last few decades to manage symptoms, but with the newer treatments that are now available, we tried to highlight what does the literature support in regards to PRRT, what does the literature support in regards to using systemic therapy for disease management, but also the benefits that you will get from a symptom management perspective using other modalities. I think the highlight really is it's a multidisciplinary approach. We are now considering surgery and embolization or interventional radiology as a critical piece. And I think the third that I'd highlight is the fact that sometimes we get too focused on carcinoid syndrome and the symptoms will actually, may result from other things. And the highlight in the algorithms that we've provided is what other things cause carcinoid-related diarrhea. And let's not forget about that because we will find ourselves treating and patients getting very frustrated with persistence of symptoms when in actuality, we should be treating something else that is causing a very similar symptom. For carcinoid heart disease, I think there are more and more guidelines that are now available to provide guidance there, but I think the major advances are that we should be utilizing heart assessment with echocardiogram with lab values such as BMP. But also critical to this is consulting with our cardiology colleagues and making sure that we're identifying heart related issues that are resulting from hormone excess sooner than later because interventions on the earlier side can really make a significant impact on quality of life and associated comorbidities and mortality. Brittany Harvey: Thank you for reviewing those key points for both carcinoid syndrome and carcinoid heart disease symptom management. So then the next set of recommendations. Dr. Del Rivero, what are the key highlights for symptom management of functioning pancreatic neuroendocrine tumors? Dr. Jaydira Del Rivero: Yes, it's very important to recognize the symptoms related to hormone excess due to pancreas neuroendocrine tumors. Up to 10% of pancreas neuroendocrine tumors may produce different hormones. Among those hormones can be insulin, gastrin, glucagon, somatostatin. So it's important to know and understand that based on what a neuroendocrine tumor is, they may produce different types of hormones. The importance of these guidelines is to also recognize some of these symptoms and how to address that, because it's not necessarily in these tumor types besides the management of metastatic disease, and know the different options that we recommend for metastatic disease from the systemic therapy, such as chemotherapy or targeted therapies or PRRT. It's important to recognize the symptoms because based on the symptoms we may recommend a different approach. That's something that is important to acknowledge and recognize. Moreover, in certain functional pancreas neuroendocrine tumors, as Dr. Perez mentioned, is a multidisciplinary approach. And it's important to also discuss these different cases with your endocrinologist. You may need to have an experienced endocrinologist to manage, for example, the excess of insulin. And also discuss your cases with a surgeon and interventional radiologist because some of these approaches can certainly improve the symptoms related to hormone excess. I understand that sometimes medical oncologists in the communities may not have access to the multidisciplinary approach or have the different teams that can manage these tumors, and that's the reason why with these guidelines we wanted to establish the understanding of different symptoms associated with the hormone excess to these neuroendocrine tumors as well as how to manage this. For example, in the case of insulinoma, I think for the medical oncologist it is important to know that the everolimus is an option to be used for these tumors, not only to manage tumor progressions related to this tumor type at the same time, because everolimus as a side effect causes hyperglycemia, that can also improve some of the symptoms related to the excess of insulin besides the somatostatin agonist. I think these recommendations will allow the medical oncologist to recognize the symptoms and based on what the symptoms cause, then you can have a different approach that could be added to the systemic therapies options as well. Brittany Harvey: Yes, beyond systemic therapy, it's important to be recognizing symptoms to provide an individualized approach for every single patient. So then, following that overview of symptom management for functioning pancreatic neuroendocrine tumors, Dr. Perez, what is recommended regarding palliative interventions for patients with gastroenteropancreatic n
