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).
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.
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).
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).
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).
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.
