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).

C. Jillian Tsai, MD, PhD, of Memorial Sloan Kettering Cancer Center, discusses results from the first randomized trial of stereotactic body radiation therapy (SBRT) to treat oligoprogressive, metastatic lung and breast cancers. The standard of care for patients with these types of tumors is to switch to a different systemic treatment. Adding local therapy such as SBRT may help treat drug-resistant lesions (Abstract LBA3).

Amar U. Kishan, MD, of the University of California, Los Angeles, discusses findings from a meta-analysis of clinical trials in patients with localized prostate cancer. The phase III results suggest that the use of androgen-deprivation therapy (ADT) or prolonged adjuvant ADT with radiotherapy may benefit patients with localized prostate cancer. Further biomarkers are needed to better personalize treatment intensification (Abstract 8).

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).

Howard M. Sandler, MD, of Cedars-Sinai Medical Center, discusses whether hypofractionation can be safely employed in the post-prostatectomy setting and the role of short-term hormone therapy in the management of intermediate-risk prostate cancer with radiotherapy.

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).
