A multicentric prospective study has been carried on 69 patients affected by peritoneal carcinomatosis from colorectal cancer. Patients have been treated by cytoreductive surgery and intraoperative hyperthermic chemoperfusion. CC 0-1 has been achieved in 82%. Major morbidity and mortality was 21.7% and 2.9% respectively. Three-yrs overall survival was 26.7% for all series. Difference in survival evaluating CC 0-1 vs. CC 2 pts and PCI < or = 10 vs. >10 was statistically significant. Evaluating only patients CC 0-1 and PCI < or = 10 4-yrs overall survival rised up to 44.7%. A smaller subgroup of patients with a disease-free interval to peritoneal carcinomatosis > or = 2-yrs showed a 5-yrs disease-free survival of 50%.


PCI < or = 10, complete or optimal cytoreduction feasibility have to be considered for the patients selection to the integrate treatment. Disease-free interval seems to be a powerful prognostic indicator and deserve to be better outlined in further studies.
