Juliane Hörner-Rieber, MD, on Breast Cancer: Boosting Intensity-Modulated and Conventional Radiotherapies
2020 ASTRO Annual Meeting
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).
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).
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).
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).
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).
