Professional Focus

Dr. Mary Feng specialized in treatment of gastrointestinal and hepatobiliary cancers. Her research focuses on technical and biological methods to individualize and adapt radiotherapy for each patient with pancreas and liver cancer to maximize the effectiveness of treatment. Her primary goals are 1) Improving outcomes for patients with pancreas and liver cancer through novel combination treatments; 2) Adapting radiotherapy based on early blood and imaging biomarkers of tumor response and treatment effects on nearby organs; and 3) Evaluating the use of advanced technologies in radiotherapy.

Dr. Feng is Vice-Chair for Clinical Research, Clinical site director for the Mission Bay Clinic, and Director of Quality Assurance and Safety for the Department of Radiation Oncology at UCSF. She also serves on numerous national and international cancer organization panels and groups, including the National Comprehensive Cancer Network Pancreatic Adenocarcinoma Panel, the American Society of Clinical Oncology Gastrointestinal Cancer Guideline Advisory Group, and the American Society for Radiation Oncology IHE-RO Clinical Advisory Subcommittee as co-chair.
