BACKGROUND: Colorectal cancer is the second leading cause of cancer-related mortality worldwide. Peritoneal metastases carry the worst prognosis among all sites of colorectal cancer metastases. In recent years, the advent and acceptance of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy have greatly improved survival for selected patients with low-volume peritoneal metastases. OBJECTIVE: Here, we report the evolution of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for colorectal peritoneal metastases at a statewide tertiary referral center over an 8-year period. DESIGN: This is a retrospective study from 2009 to 2017. SETTING: The study was conducted at a single center over 8 years. PATIENTS: Patients with colorectal peritoneal metastases undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were included. MAIN OUTCOMES: Main outcomes included evaluation of grade III/IV morbidity rate, mortality rate, overall and relapse-free survival, and prognostic factors influencing survival on a Cox multivariate analysis model. RESULTS: One hundred one cytoreductive surgeries were undertaken on 96 patients during this time for colorectal peritoneal metastases. The median patient age was 60 years with 55.2% being female. The median Peritoneal Carcinomatosis Index was 9, with complete cytoreduction achieved in 76 (75.2%) cases. Grade III or IV complications occurred in 26 cases (25.7%) with 2 (2%) perioperative mortalities. Median overall survival for the entire cohort was 32 months, with a 3-year survival of 38%. For patients who achieved a complete cytoreduction, median overall survival was 37 months, with a relapse-free survival of 13 months and a 3-year survival of 54%. Complete cytoreduction and nonmucinous histology were key factors independently associated with improved overall survival. LIMITATIONS: The main limitation this study is its retrospective nature. CONCLUSION: Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy for isolated low-volume colorectal peritoneal metastases are not safe and effective, with low morbidity. It offers selected patients a highly favorable overall and relapse-free survival. See Video Abstract at http://links.lww.com/DCR/B2.
