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).

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).

Toni K. Choueiri, MD, of Dana-Farber Cancer Institute, describes a currently recruiting phase III study (COSMIC-313) of cabozantinib in combination with nivolumab and ipilimumab vs nivolumab/ipilimumab for patients with previously untreated advanced renal cell carcinoma of intermediate or poor risk (Abstract TPS767).
The ASCO Post Staff
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).

Karim Fizazi, MD, PhD, of the Institut Gustave Roussy, discusses results from the CARD study, which showed that cabazitaxel improved pain, time to pain progression, and symptomatic skeletal events, as well as quality of life in patients with metastatic castration-resistant prostate cancer. The findings support the use of this agent as a standard of care (Abstract 16).

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).
