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).
Nicholas D. James, PhD, MBBS, of The Institute of Cancer Research in London, discusses the health economics of adding abiraterone to first-line, long-term hormone therapy in prostate cancer, and what it means for long-term survival, quality-adjusted survival, and cost-effectiveness (Abstract 204).
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).
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).
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).
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).
