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).
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).

Arjun Sahgal, MD, of the Sunnybrook Health Sciences Centre, discusses results of the first phase III trial to suggest that dose escalation with stereotactic body radiotherapy may be superior to conventional palliative radiotherapy in improving pain outcomes for patients with spinal bone metastases (Abstract LBA2).
The ASCO Post Staff
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.

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).
