RESUMO

BACKGROUND AND OBJECTIVES: The aims of this multi-institutional study were to assess the feasibility of iterative cytoreductive surgery (iCRS)/hyperthermic intraperitoneal chemotherapy, iCRS in colorectal peritoneal carcinomatosis (CRPC), evaluate survival, recurrence, morbidity and mortality outcomes, and identify prognostic factors for overall survival. METHODS: Patients with CRPC that underwent an iCRS, with or without intraperitoneal chemotherapy, from June 1993 to July 2016 at 13 institutions were retrospectively analyzed from prospectively maintained databases. RESULTS: The study comprised of 231 patients, including 126 females (54.5%) with a mean age at iCRS of 51.3 years. The iterative high-grade (3/4) morbidity and mortality rates were 23.4% and 1.7%, respectively. The median recurrence-free survival was 15.0 and 10.1 months after initial and iCRS, respectively. The median and 5-year survivals were 49.1 months and 43% and 26.4 months and 26% from the initial and iCRS, respectively. Independent negative predictors of survival from the initial CRS included peritoneal carcinomatosis index (PCI) > 20 ( P = 0.02) and lymph node positivity ( P = 0.04), and from iCRS, PCI > 10 ( P = 0.03 for PCI 11-20; P < 0.001 for PCI > 20), high-grade complications ( P = 0.012), and incomplete cytoreduction ( P < 0.001). CONCLUSION: iCRS can provide long-term survival benefits to highly selected colorectal peritoneal carcinomatosis patients with comparable mortality and morbidity rates to the initial CRS procedure. Careful patient selection is necessary to improve overall outcomes.
