Overview

Dr. Sean Dineen is an Assistant Member of the Department of Gastrointestinal Oncology at Moffitt Cancer Center. Dr. Dineen has a particular interest in the treatment of patients with metastatic disease, including carcinomatosis. In particular, he focuses on patients that have developed peritoneal spread of disease and the application of heated intraperitoneal chemotherapy (HIPEC) in the treatment of this advanced process. Dr. Dineen’s research focuses on identifying how the tumor and the local environment interact to promote metastatic disease. Dr. Dineen is a native of Lexington, KY. He earned his medical degree from the University of Louisville. He completed residency in general surgery at UT Southwestern in Dallas, which included a research fellowship focused on the tumor microenvironment. He subsequently completed a fellowship in Complex General Surgical Oncology at MD Anderson Cancer Center, where he earned the Clinical Excellence award from the Department of Surgery. Dr. Dineen joins Moffitt from the University of Kentucky, where he was previously the Medical Director of the Multidisciplinary Clinic at Markey Cancer Center. Dr. Dineen has an excellent publication record and has presented nationally and internationally on GI and peritoneal diseases. He is a member of the American College of Surgeons (ACS), the Americas Hepato-Pancreato-Biliary Association (AHPBA) and the Society for Surgeons of the Alimentary Tract (SSAT).
