C. Jillian Tsai, MD, PhD, on Using Radiotherapy to Thwart Tumor Growth in Advanced Cancers
2021 ASTRO Annual Meeting
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).

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).

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).
The ASCO Post Staff
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).

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.

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).
