Daniel E. Spratt, MD, on Prostate Cancer: Short-Term Adjuvant vs Neoadjuvant Hormone Therapy
2020 ASTRO Annual Meeting
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).

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).
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).

Alphonse G. Taghian, MD, PhD, of Massachusetts General Hospital, reviews the 10-year follow-up of a dose-escalation trial studying accelerated partial-breast irradiation and discusses the optimal dose, adverse effects, and cosmetic outcomes (Abstract 25).

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).

Youssef Zeidan, MD, PhD, of the American University of Beirut Medical Center, discusses study findings showing that breast-conserving surgery, whole-breast irradiation, and trastuzumab offer effective local tumor control for patients with HER2-positive breast cancer. An additional radiation boost does not seem to further improve outcomes (Abstract 52).
