Neha Vapiwala, MD, on Prostate Cancer: Imaging and the Decision to Treat With Radiation
2020 ASTRO Annual Meeting
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.

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).

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).

Cynthia Menard, MD, of the University of Montreal, discusses a study on the use of prostate-specific membrane antigen PET and CT to guide treatment. The scans led to high rates of new lesion detection and therefore intensification of radiotherapy for patients with prostate cancer, without an increase in side effects (Abstract 34).

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).

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).
