Background: Peritoneal metastases carry the worst prognosis among all sites of colorectal cancer (CRC) metastases. In recent years, the advent of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has improved survival for selected patients with limited peritoneal involvement. We report the evolution of CRS and HIPEC for colorectal peritoneal metastases at a tertiary referral center over a 10-year period. Methods: Patients with colorectal peritoneal metastases undergoing CRS and HIPEC were included and retrospectively analyzed at a tertiary referral center from January 2006 to December 2015. Main outcomes included evaluation of grade III/IV complications, mortality rate, overall and disease-free survival, and prognostic factors influencing survival on a Cox multivariate analysis. Results: Sixty-seven CRSs were performed on 67 patients during this time for colorectal peritoneal metastases. The median patient age was 57 years with 55.2% being female. The median peritoneal carcinomatosis index (PCI) was 7, with complete cytoreduction achieved in 65 (97%) cases. Grade > 2 complications occurred in 6 cases (8.9%) with no mortality. The median overall survival for the entire cohort was 41 months, with a 3-year overall survival of 43%. In case of complete cytoreduction, median overall and disease-free survival were 57 months and 36 months respectively, with a 3-year disease-free survival of 62%. Complete cytoreduction and nonmucinous histology were key factors independently associated with improved overall survival. Conclusions: CRS and HIPEC for limited peritoneal metastases from CRC are safe and effective, with acceptable morbidity. In selected patients, it offers a highly favorable long-term outcomes.
