Résumé : Peritoneal carcinomatosis (PC) from colorectal cancer is a dreadful situation characterized by a rapid and mortal evolution (median survival of 5 to 7 months amongst the series published in the literature). The classical treatment includes systemic chemotherapy whether or not associated with palliative surgery. Since the early nineties, locoregional treatments combining extensive cytoreductive surgery with intraperitoneal hyperthermic chemotherapy have been developed, affording some patients a cure and yealding a 5-year survival as high as 30 to 40% in some series. However, it is associated with high morbidity and mortality rates.
