James B. Yu, MD, of Yale School of Medicine, summarizes the plenary lecture on results from the NRG Oncology/phase III study comparing two fractionation schedules for low-risk prostate cancer (Abstract LBA6).
Stephen G. Chun, MD, of MD Anderson Cancer Center, discusses the comparison of 3D conformal and IMRT outcomes for locally advanced non-small cell lung cancer (Abstract 2).
Joel E. Tepper, MD, of the University of North Carolina School of Medicine, discusses the ways in which SBRT has changed radiotherapy, as demonstrated in key studies presented at this year's meeting on stereotactic body radiotherapy for liver metastases and hepatocellular carcinoma, and borderline resectable and unresectable pancreatic tumors (Abstracts 253, 255, 351, 357).
Catherine C. Park, MD, of the University of California, San Francisco, summarizes results from three clinical trials of radiation therapy for various cancers: metastatic melanoma, oropharyngeal squamous cell carcinoma, and breast cancer (Abstracts 215, 3, and LBA7).
Jay Harris, MD, of Dana-Farber Cancer Institute and Brigham and Women’s Hospital, discusses the difficulty reconciling recent important trials on radiotherapy for breast cancer: The Z11 trial suggested that breast tangents are sufficient, while MA.20 and EORTC studies suggested that full nodal irradiation is beneficial.
Leonard Gunderson, MD, of the Mayo Clinic College of Medicine, discusses PET/CT imaging in upper and lower gastrointestinal cancers, which can be of value as a baseline study prior to treatment, in determining the degree of response to treatment, and in helping decide whether there is a relapse after a complete response to treatment.
