Gastrointestinal Cancer Program

Radiation Therapy for Gastrointestinal Cancers

Director: Bryan W. Chang, MD

Patients with gastrointestinal cancers are cared for by a multidisciplinary team consisting of surgeons, radiation oncologists, medical oncologists and gastroenterologists. Our radiation oncologists have expertise in the management of esophageal, gastric, pancreatic, hepatic, biliary, rectal, and anal cancers using both 3-dimensional conformal and intensity-modulated radiation therapy (IMRT). The department is equipped with the latest in 4-dimensional CT simulation and image-guided radiation therapy (IGRT) equipment, which are used routinely to ensure that treatments are delivered with precision and accuracy. Our team also includes experienced nurses, a dietitian, and a massage therapist.

Stereotactic Body Radiation Therapy (SBRT) for Liver Tumors

Selected patients with tumors of the liver that can not be treated with surgery or other local therapies may be offered stereotactic body radiation therapy (SBRT). SBRT is a highly potent and completely noninvasive technique for ablating liver tumors. Simulation is performed with a 4-dimensional CT or cine magnetic resonance imaging (MRI) scan to evaluate tumor and organ motion, and a highly customized treatment plan is created to deliver a powerful and focused dose of radiation to the target. Treatment is typically performed in 3 to 5 sessions.
