I conduct clinical research on a variety of gastrointestinal cancers and provide care for patients with those cancers. We have trials of combined modality therapy (surgery +/- radiation +/- chemotherapy) on gastric, esophageal, pancreas and rectal cancers. We also perform phase I and II trials of biologically targeted agents as well as newer immunotherapeutics. In collaboration with a number of colleagues, we conduct translational studies analyzing novel imaging (e.g. contrast enhanced ultrasound and perfusion scans) and molecular biomarkers (e.g. CDX2 as a prognostic and predictive factor in colon cancer and matrix metalloproteinases as prognostic factors in pancreas cancer).
