Background: Peritoneal carcinomatosis (PC) from colorectal cancer is associated with a poor prognosis. Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) have improved survival compared to systemic chemotherapy. We evaluate the results of this treatment in our institution.
Methods: Treatment consisted of complete CRS followed by HIPEC with oxaliplatin (460 mg/m(2) ) in 2 L/m(2) of D5W at 42°C during 30 min.
Results: From 2004 to 2011, 40 patients with PC from colorectal cancer were included and 25 CRS + HIPEC were performed. Six patients had a negative second-look surgery and nine had unresectable disease. Median follow-up was 22.8 months. Overall 3- and 5-year survival rates for the cohort were 56% and 33%. The 3- and 5-year overall survival rates were 61% and 36% for HIPEC group, 82% and 67% for patients with negative second-look, and 22% and 0% for the unresectable group (P = 0.0087). 3-year disease-free survival for HIPEC group was 22%. Major complication and mortality rate for HIPEC group were 20% and 4%. Peritoneal carcinomatosis index (P = 0.0374) and lymph node status (P = 0.027) were prognostic indicators.
Conclusions: CRS + HIPEC with oxaliplatin for PC from colorectal cancer is an effective treatment with encouraging survival results.
