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).
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).
Ziad Bakouny, MD, of Dana-Farber Cancer Institute, discusses two types of renal cell cancer that are associated with poor prognosis. Because recent early data suggest these tumors respond well to immune checkpoint inhibitors, the authors characterized the tumors in an integrative molecular and clinical study (Abstract 715).
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).
Thomas Powles, MD, PhD, of Queen Mary University of London, summarizes two papers on metastatic renal cell carcinoma for which he was the discussant: nivolumab in combination with stereotactic body radiotherapy in pretreated patients, and combining dual immune checkpoint inhibition with stereotactic radiation (Abstracts 613 & 614).
Nizar M. Tannir, MD, of The University of Texas MD Anderson Cancer Center, discusses overall survival and an independent review of response in CheckMate 214 with 42-month follow-up, using first-line nivolumab plus ipilimumab vs sunitinib in patients with advanced renal cell carcinoma (Abstract 609).
