Gastrointestinal / Hepatobiliary Oncology Program

Physicians Reviewing PaperworkThe Gastrointestinal/Hepatobiliary Oncology Program is a multidisciplinary clinical and scientific program that provides comprehensive services to patients with pre-cancerous and cancerous conditions involving the esophagus, stomach, small intestines, colon, rectum, pancreas, biliary tract, liver, retroperitoneum, and other intra-abdominal organs. The program emphasizes the comprehensive evaluation of patients with a close collaboration of multiple specialists including surgical oncologists, medical oncologists, radiation oncologists, gastroenterologists, radiologists, pathologists, nurses, pharmacists and social workers.

David August, MDThe Gastrointestinal (GI) Group meets on a weekly basis to address clinical and research issues relating to all types of GI malignancies. The team discusses treatment and patient care issues to assure that the full spectrum of cancer prevention, diagnosis, treatment and follow-up options are appropriately considered for every patient. The program integrates a spectrum of clinical, basic, and translational research activities, assuring close collaboration between basic scientists and clinicians for the rapid translation of research discoveries to clinical care and to enlist the assistance of basic researchers in solving clinical problems.

The clinical arm of the program provides interdisciplinary diagnostic and treatment options that include prevention in high risk populations, early diagnosis, therapeutic evaluations, multi-disciplinary management of patients with cancer and pre-cancerous conditions, and treatment of advanced disease. The program strives to make new prevention, diagnostic, and treatment approaches available to patients through clinical trials.
