Daniel E. Spratt, MD, on the Impact of Antiandrogen Treatment in Prostate Cancer: NRG Oncology/RTOG 9601 Trial
2019 ASTRO Annual Meeting
Daniel E. Spratt, MD, of the University of Michigan, discusses phase III study findings showing that 2 years of antiandrogen therapy increased cardiac and neurologic toxicities, as well as mortality from causes other than prostate cancer, in men with low levels of prostate-specific antigen after prostatectomy who received adjuvant early salvage radiotherapy (Abstract LBA1).
Erica H. Bell, PhD, of The Ohio State University, discusses phase III findings from a prognostic and predictive molecular subgroup analysis of radiotherapy vs radiotherapy plus procarbazine/lomustine/vincristine in high-risk low-grade gliomas (Abstract 161).
Andrew Kneebone, MD, of Royal North Shore Hospital, discusses phase III study findings showing that at 5 years, biochemical control was similar between adjuvant and early salvage radiotherapies, the latter sparing half of the men potential side effects of radiotherapy without any significant compromise in outcome (Abstract 77).
Robert Olson, MD, of the BC Cancer Centre for the North, discusses a secondary analysis of the SABR-COMET trial, which showed there was a small magnitude decline in quality of life in both arms of the study but no associated detriment with stereotactic ablative radiotherapy (Abstract 148).
Daniel M. Trifiletti, MD, of the Mayo Clinic, discusses study findings showing that, between two different radiation doses (30 Gy/10 fractions vs 37.5 Gy/15 fractions), there was no difference in the time to cognitive failure, tumor control, or overall survival for patients with brain metastases (Abstract 19).
Youssef Zeidan, MD, PhD, of the American University of Beirut Medical Center, discusses study findings showing that, in patients with one to three positive lymph nodes, postmastectomy radiation treatment decreased the risk of locoregional recurrence, particularly in estrogen receptor–positive disease (Abstract 83).
