[Peritoneal carcinomatosis treated by cytoreductive surgery and intraperitoneal chemohyperthermia].
OBJECTIVE
The aim of this prospective non-randomized trial was to report a series of intraperitoneal carcinomatosis due to miscellaneous causes, treated by intraperitoneal hyperthermic perfusion (IPHP) and cytoreductive surgery.


METHODS
From January 1995 to May 1999, 35 patients were treated by IPHP and 26 of them underwent maximal cytoreductive surgery. IPHP was performed for 60 minutes at an intraperitoneal temperature of 42 degrees C with Mitomycin C (10 mg/L) or cisplatinum (12 mg/L) at a flow rate of 0.9 L/min.


RESULTS
There was one (2.8%) postoperative death due to respiratory complications on day 16. Three patients (8.5%) were admitted to the intensive care unit. A high morbidity rate (54%) was observed with intra-abdominal complications in 28.5% of patients, requiring reoperation in three patients. In patients with stages 1 and 2 peritoneal carcinomatosis (granulations less than 5 mm), the 12- and 24-month survival rates were 63.1% and 31.5%, respectively. In patients with advanced stage 3 (diffuse malignant nodules less than 2 cm) and stage 4 carcinomatosis (malignant nodules larger than 2 cm), the 12- and 24-month survival rates were 31.2% and 12%, respectively. Six patients survived for more than 30 months.


CONCLUSIONS
IPHP appears to be an effective treatment for peritoneal carcinomatosis. IPHP combined with cytoreductive surgery is aggressive with a high morbidity rate. Rigorous patient selection is necessary. IPHP is still under evaluation. Prospective randomized trials with identical IPHP protocols are required.
