Morbidity and mortality of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the management of peritoneal carcinomatosis.

PURPOSE: Peritoneal carcinomatosis (PC), which has been regarded as a lethal condition, may now be treated, achieving a long-term disease-free survival with cytoreductive surgery by treating macroscopic tumor seeding and hyperthermic intraperitoneal chemotherapy (HIPEC) by treating residual microscopic disease. The purpose of this study was to analyse the morbidity and mortality of this procedure. METHODS: A total of 39 consecutive patients were included in this retrospective study. After complete resection of the PC, HIPEC was performed via the coliseum technique. The chemotherapeutic agents used depended on the tumors' histology. RESULTS: Postoperative mortality and morbidity rates were 5.1%% (2/39) and 43.5% (17/39), respectively. The most frequent complications were pulmonary complications (31%), gastrointestinal fistulas (20%), hematologic toxicity (16%) and postoperative bleeding (11%). Statistical correlations were evidenced between morbidity and PC index (p<0.004), duration of surgery (p<0.001) and blood loss (p<0.001). CONCLUSION: This approach has resulted in a relatively high but acceptable percent of adverse events considering the expected advantage for survival.
