Emerging Treatment Paradigms in Genitourinary Cancers

Dr. Pedro Barata and Dr. Rana McKay discuss the integration of innovative advances in molecular imaging and therapeutics to personalize treatment for patients with renal cell and urothelial carcinomas. TRANSCRIPT Dr. Pedro Barata: Hello, I'm Dr. Pedro Barata, your guest host of By the Book, a podcast series featuring insightful conversations between authors and editors of the ASCO Educational Book. 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 an associate editor of the ASCO Educational Book. Now, we all know the field of genitourinary cancers (GU) is evolving quite rapidly, and we have new innovations in molecular imaging as well as targeted therapeutics. Today's episode will be exploring novel approaches that are transforming the management of renal cell and urothelial carcinomas and also their potential to offer a more personalized treatment to patients. For that, joining for today's discussion is Dr. Rana McKay, a GU medical oncologist and professor at University of California San Diego. Dr. McKay will discuss her recently published article titled, "Emerging Paradigms in Genitourinary Cancers: Integrating Molecular Imaging, Hypoxia-Inducible Factor-Targeted Therapies, and Antibody-Drug Conjugates in Renal Cell and Urothelial Carcinomas." Our full disclosures are available in the transcript of this episode. And with that, Rana McKay, great to have you on the podcast today. Dr. Rana McKay: Oh, thank you so much, Dr. Barata. It's really wonderful to be here with you. So, thanks for hosting. Dr. Pedro Barata: No, thanks for taking the time, and I'm looking forward to this conversation. And by the way, let me start by saying congrats on a great article in the Educational Book. Really super helpful paper. I'm recommending it to a lot of the residents and fellows at my own institution. I would like to first ask you to kind of give our listeners some context of how novel approaches in the molecular imaging as well as targeted therapeutics are actually changing the way we're managing patients with GU, but specifically with renal cell carcinoma and urothelial carcinoma. So, what are the areas you would call out as like being big areas for innovation in this context, and why are they important? Dr. Rana McKay: Very good question. And I think this is really what this article highlights. It highlights where are we going from an imaging diagnostics standpoint? Where are we going from a therapeutic standpoint? And I think if we have to step back, from the standpoint of diagnostics, we've seen PET imaging really transform diagnostics in prostate cancer with the advent of PSMA PET imaging, and now PSMA PET imaging is used as a biomarker for selection for theranostics therapy. And so, we're starting to see that enter into the RCC landscape, enter into the urothelial cancer landscape to a lesser extent. And I think it's going to potentially be transformative as these tools get more refined. I think when we think about therapeutics, what's been transformative most recently in the renal cell carcinoma landscape has been the advent of HIF2α inhibition to improve outcomes for patients. And we have seen the approval of belzutifan most recently that has reshaped the landscape. And now there's other HIF2α inhibitors that are being developed that are going to be further important as they get refined. And lastly, I think when we think about urothelial carcinoma, the greatest transformation to treatment in that context has been the displacement of cisplatin and platinum-based chemotherapy as a frontline standard with the combination of enfortumab vedotin plus pembrolizumab. And we've seen antibody-drug conjugates really reshape treatment and tremendously improve outcomes for patients. So, I think those are the three key areas of interest. Dr. Pedro Barata: So with that, let's focus first on the imaging and then
