Jing Li, MD, PhD, on Brain Metastases: Stereotactic Radiosurgery vs Whole-Brain Radiation Therapy
2020 ASTRO Annual Meeting
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).
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).
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).
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).
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).
