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.

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).

David A. Palma, MD, PhD, of Ontario’s London Health Sciences Centre, discusses results of the ORATOR2 study, which compared two treatment options that could be de-escalated for patients with HPV-associated oropharyngeal squamous cell carcinoma: a lower-dose radiation approach (6 weeks instead of 7, often with chemotherapy) vs a transoral surgical approach (with low-dose radiation afterward, for 5 weeks) (Abstract LBA2).

Benjamin Movsas, MD, of the Henry Ford Cancer Center, discusses results from the NRG Oncology/RTOG 0815 study, which explored dose-escalated radiotherapy alone or in combination with short-term hormonal therapy for patients with intermediate-risk prostate cancer. In addition to clinical outcomes, Dr. Movsas discusses patient-reported results in the study that may help patients make informed decisions when choosing between these treatment options (Abstract 4).

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.
