Linda G.W. Kerkmeijer, MD, PhD, on Prostate Cancer: Adding a Focal Boost to External-Beam Radiotherapy
2020 ASTRO Annual Meeting
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 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).

Neha Vapiwala, MD, of the University of Pennsylvania, who served as a discussant for LBA1, summarizes her review of this study of patients with prostate cancer who had biochemical recurrence in the post-prostatectomy setting, who were candidates for salvage radiotherapy, and who received either conventional imaging or PET scans to help determine the course of treatment.
Juliane Hörner-Rieber, MD, of Heidelberg University Hospital, discusses phase III results of the MINT trial, which showed that conventionally fractionated intensity-modulated radiotherapy with a simultaneous integrated boost was noninferior to three-dimensional conformal radiotherapy followed by a sequential boost for both local control and cosmesis in patients with breast cancer (Abstract 19).

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).
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).
