David A. Palma, MD, PhD, on HPV-Associated Oropharyngeal Squamous Cell Carcinoma: Radiotherapy vs Surgery
2021 ASTRO Annual Meeting
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).

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).

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).

Youssef Zeidan, MD, PhD, of Florida International University and the Lynn Cancer Institute, discusses the advances in radiotherapy planning and delivery that have reduced cardiac radiation exposure in patients with HER2-positive breast cancer who are treated with radiotherapy and trastuzumab (Abstract 12).
The ASCO Post Staff
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.

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).
