Gastrointestinal Malignancies

Research Abstract

My major research interests are soft tissue sarcomas and gastrointestinal cancers. My focus in soft tissue sarcomas includes evaluating histologic and immunohistochemical parameters that predict clinical outcome, and identifying diagnostically useful immunophenotypic markers. The sarcomas I currently study include gastrointestinal stromal tumors (GIST), leiomyosarcomas, histiocytic and dendritic cell sarcomas, and neural tumors of skin and soft tissue. My focus in gastrointestinal cancer is the pathology of Barrett's esophagus and associated dysplasia and adenocarcinoma, in particular with the goal of improving the prognostic value of endoscopic surveillance biopsies, and studying the clonal evolution of neoplasia in Barrett's esophagus. In addition to esophageal adenocarcinoma, I also study colorectal carcinoma and pancreatic carcinoma.
