Actual 5-Year Survival After Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy for Patients with Peritoneal Carcinomatosis of Colorectal Origin

Background Cytoreductive surgery and heated intraperitoneal chemotherapy (CRS/HIPEC) improves survival compared with chemotherapy alone in patients with peritoneal carcinomatosis (PC) of colorectal (CRC) origin, however, long-term survival data are lacking. We report the actual survival of patients who underwent CRS/HIPEC for PC of CRC origin with a minimum potential 5-year follow-up period to identify factors that preclude long-term survival. Methods We performed a retrospective analysis of a prospective database, analyzing patients undergoing CRS/HIPEC for PC of CRC origin from 2007 to 2017. Patients with aborted CRS/HIPEC, postoperative follow-up
