[Complications and tolerance of heated intraperitoneal chemotherapy and cytoreductive surgery for peritoneal carcinomatosis: results of a phase I-II study of peritoneal carcinomatosis from different sources].

Peritoneal carcinomatosis represents the terminal stage of adenocarcinomas of the gastrointestinal tract. A new treatment combining cytoreductive surgery and intraperitoneal chemotherapy-hyperthermia has been used with encouraging results. The purpose of this study was to report the complications associated with this treatment. Fourty procedures were carry out in 37 patients. Death occurred in 3 patients. Major medical complications were 13 pulmonary infections, 11 acute renal failure (with only 3 who needed dialysis) and 10 patients with neutropenia grade 3 and 4 toxicity. Intra-abdominal complications occurred in 16 patients (there were 11 anastomotic leak and/or bowel perforation, and 12 intra-abdominal infections). Some complications like secretory diarrhea or tubulopathia which were related to these treatment need further investigations. Six procedures were without any complications, 6 presented minor ones and 22 major complications. Adverse effects were relatively important with this new treatment strategy. This was maybe due to a learning process; there is no death and only one anastomotic leak in our last study including 30 patients with cytoreductive surgery and intraperitoneal chemotherapy-hyperthermia.
