Jeff M. Michalski, MD, MBA, on Medulloblastoma and Radiation Treatment in Pediatric Patients
2020 ASTRO Annual Meeting
Jeff M. Michalski, MD, MBA, of the Washington University School of Medicine, discusses a Children’s Oncology Group study that confirmed data previously reported: Involved-field radiotherapy is noninferior to posterior fossa radiotherapy in patients with average risk-medulloblastoma. However, low-dose craniospinal irradiation is not as effective as standard-dose irradiation in younger children (Abstract 1).

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).

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).
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).

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).
