Systemic Chemotherapy With or Without Intraperitoneal Chemohyperthermia in Treating Patients Undergoing Surgery for Peritoneal Carcinomatosis From Colorectal Cancer

RATIONALE: Drugs used in chemotherapy, such as leucovorin, fluorouracil, and oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether systemic chemotherapy is more effective with or without intraperitoneal chemohyperthermia in treating patients with peritoneal carcinomatosis from colorectal cancer.
PURPOSE: This randomized phase III trial is studying systemic chemotherapy to see how well it works compared with or without intraperitoneal chemohyperthermia in treating patients undergoing surgery for peritoneal carcinomatosis from colorectal cancer.
