David P. Dearnaley, MD, on Prostate Cancer: Conventional vs Hypofractionated High-Dose Radiotherapy
2020 Genitourinary Cancers Symposium
David P. Dearnaley, MD, of The Institute of Cancer Research and Royal Marsden NHS Foundation Trust, discusses 8-year outcomes of the phase III CHHiP trial, which showed that modest hypofractionation is noninferior to conventional fractionation in localized prostate cancer, with no increase in side effects. Disease control was also reported in patients older than age 75 (Abstract 325).
Jonathan E. Rosenberg, MD, of Memorial Sloan Kettering Cancer Center, discusses study results which showed that, in first-line cisplatin-ineligible patients with metastatic urothelial carcinoma, enfortumab vedotin/pembrolizumab demonstrated activity and durability, with a manageable safety profile (Abstract 441).
Julie N. Graff, MD, of Oregon Health & Science University and Knight Cancer Institute, discusses study findings that show pembrolizumab plus enzalutamide after progression on enzalutamide produced clinical activity and can lead to durable responses, with a manageable safety profile. The phase III KEYNOTE-641 trial will test patients who are enzalutamide-naive (Abstract 15).
Hannah L. Rush, MBChB, of the Clinical Trials Unit at University College London, discusses an analysis of the STAMPEDE trial, which showed that patients treated with abiraterone had higher scores in global quality of life as well as in the physical, social, and role function domains and lower scores for pain and fatigue over the first 2 years than those receiving docetaxel (Abstract 14).
Maha Hussain, MD, of the Robert H. Lurie Comprehensive Cancer Center of Northwestern University, discusses the first phase III clinical trial to demonstrate the feasibility of tissue-based genomic testing to preselect men with metastatic castration-resistant prostate cancer for targeted treatment and the superiority of the PARP inhibitor olaparib compared to enzalutamide or abiraterone (Abstract 195).
Neeraj Agarwal, MD, of the University of Utah Huntsman Cancer Institute, discusses trial findings that showed the combination of cabozantinib and atezolizumab had a tolerable safety profile and showed activity in men with metastatic disease. Further evaluation of cabozantinib and atezolizumab is planned in a phase III trial (Abstract 82).
