Vinai Gondi, MD, on Glioblastoma: Dose Intensification, IMRT, Standard Radiotherapy, and Temozolomide
2020 ASTRO Annual Meeting
Vinai Gondi, MD, of Northwestern Medicine Cancer Center and Northwestern Medicine Proton Center, discusses the preliminary results of an NRG Oncology study of radiotherapy dose intensification using intensity-modulated radiotherapy vs standard-dose radiotherapy with temozolomide in patients with newly diagnosed glioblastoma (Abstract 42).

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).

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).

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).

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).
