Intraperitoneal Hyperthermic Perfusion With Oxaliplatin in Treating Patients With Stage IV Peritoneal Cancer Due to Appendix Cancer or Colorectal Cancer

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Hyperthermia therapy kills tumor cells by heating them to several degrees above normal body temperature. Adding chemotherapy to hyperthermia and infusing it directly into the abdomen may kill more tumor cells. Giving this treatment after surgery may kill any tumor cells that remain after surgery. PURPOSE: This phase I trial is studying the side effects and best dose of intraperitoneal hyperthermic perfusion with oxaliplatin in treating patients with stage IV peritoneal cancer due to appendix cancer or colorectal cancer.
