Mark K. Buyyounouski, MD, MS, on Prostate Cancer: Hypofractionated vs Conventional Radiotherapy After Surgery
2021 ASTRO Annual Meeting
Mark K. Buyyounouski, MD, MS, of Stanford University, discusses phase III results from the NRG Oncology GU003 trial, which showed that, post-prostatectomy, using fewer—but higher—doses of radiation does not appear to increase long-term side effects or reduce quality of life when compared with conventional radiation treatment (Abstract 3).

Daniel F. Hayes, MD, of the University of Michigan Rogel Cancer Center, discusses whether liquid biopsies can provide insight into the challenge of curing metastatic breast and possibly other cancers, how oligometastases are similar to a primary cancer, and why some kinds of local therapy for widespread disease might improve survival and lead to a cure.
The ASCO Post Staff
Robert A. Olson, MD, of the University of British Columbia, discusses phase II findings from the SABR-5 trial on stereotactic ablative radiotherapy for up to five oligometastases. Although toxicity of liver and adrenal metastases warrants caution, the trial seemed to show that this type of radiation treatment is relatively safe and should be studied further, given the long overall survival in this patient population (Abstract 6).

Diana D. Shi, MD, of Dana-Farber Cancer Institute and Brigham and Women’s Cancer Center, discusses studies being planned and already underway to test BAY 2402234, a de novo pyrimidine synthesis inhibitor that possibly could be used clinically to target IDH-mutant gliomas and may act as a tumor-selective radiosensitizer (Abstract 167).
The ASCO Post Staff
Erin Murphy, MD, of Cleveland Clinic, discusses new data that show no apparent difference in cognitive performance up to 2 years post-treatment among adults with low-grade glioma who were treated with concurrent radiotherapy and temozolomide (Abstract 3258).
The ASCO Post Staff
Yongbae Kim, MD, of the Yonsei Cancer Center and Yonsei University College of Medicine, discusses findings that showed the use of internal mammary area irradiation (IMNI) in regional nodal irradiation did not significantly improve disease-free survival for women with node-positive breast cancer. However, patients with medially or centrally located tumors may be considered for treatment with IMNI (Abstract 2).
