Daniel E. Spratt, MD, on Prostate Cancer: Relugolix vs Leuprolide
2020 ASTRO Annual Meeting
Daniel E. Spratt, MD, of the University of Michigan Rogel Cancer Center, discusses phase III results of the HERO trial, which suggested benefits of the oral medication relugolix: a substantially faster time to castration with longer duration, fewer cardiac events, and a faster return to normal testosterone levels compared with leuroplide (Abstract 35).
Paul Sargos, MD, of the Institut Bergonié, discusses phase III findings from the GETUG-AFU 17 study, which compared adjuvant vs early salvage radiotherapy, both combined with short-term androgen-deprivation therapy after radical prostatectomy for localized prostate cancer. Although lacking statistical power, the study showed no benefit in event-free survival for adjuvant compared to salvage radiotherapy (Abstract 33).
Linda G.W. Kerkmeijer, MD, PhD, of the University Medical Center Utrecht and Radboud University Medical Center, discusses results from the phase III FLAME trial, which explored the question of whether biochemical disease–free survival can be improved by adding a focal boost to the intraprostatic lesion in whole-gland external-beam radiotherapy for patients with intermediate- and high-risk prostate cancers (Abstract 126).
Daniel E. Spratt, MD, of the University of Michigan Rogel Cancer Center, discusses a pooled analysis of two phase III trials showing adjuvant androgen-deprivation therapy (ADT) improves biochemical control and reduces distant metastasis when compared with a neoadjuvant approach, with no difference in late gastrointestinal or genitourinary toxicities. The analysis also showed that delaying radiotherapy to deliver neoadjuvant ADT did not benefit most patients (Abstract 32).
Jing Li, MD, PhD, of The University of Texas MD Anderson Cancer Center, discusses phase III results showing the use of stereotactic radiosurgery in patients with 4 to 15 brain metastases, compared with whole-brain radiotherapy, may better preserve cognitive function and minimize the interruption of systemic therapy without compromising overall survival (Abstract 41).
Justin Oh, MD, of the University of British Columbia, discusses results from the ASCENDE-RT trial, which compared a low-dose–rate brachytherapy boost to a dose-escalated external-beam boost for patients with high- and intermediate-risk prostate cancers (Abstract 127).
