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).

Aadel A. Chaudhuri, MD, PhD, of Washington University School of Medicine in St. Louis, discusses circulating tumor DNA, which has the potential to better personalize treatment for patients with oligometastatic cancer and help clinicians determine whether to offer systemic therapy alone or curative-intent local consolidative therapy.

Daniel J. Ma, MD, of the Mayo Clinic Alix School of Medicine, discusses results from a phase III study of patients with HPV-associated oropharyngeal squamous cell carcinoma. Comparing a 2-week course of de-escalated adjuvant radiation therapy with the standard 6-week course, investigators found that the shorter treatment appeared to have less toxicity, higher quality of life, and similar disease control as the longer standard-of-care treatment (Abstract LBA1).

Shauna Campbell, DO, of Cleveland Clinic, discusses results from her study that showed hypofractionated intensity-modulated radiation therapy (H-IMRT) in the definitive or postoperative treatment of head and neck cancers using ≥ 50 Gy in 20 fractions appears to be safe and well tolerated with modest toxicity. Dr. Campbell suggests that prospective studies comparing the safety and efficacy of H-IMRT with those of conventionally fractionated IMRT are warranted (Abstract 2313).

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).

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).
