Mapping the location of peritoneal metastases using the peritoneal cancer index and the correlation with overall survival: a retrospective study.

Purpose: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is a promising treatment for patients with peritoneal carcinomatosis (PC). Our objective was to identify new prognostic factors within the Peritoneal Cancer Index (PCI) score in PC patients.

Methods: 140 patients (60 ovarian, 45 colon, 14 gastric, 10 pseudomyxoma peritonei, 5 mesothelioma, 6 sarcoma) with PC treated with CRS+HIPEC from 2007 to December 2013 were retrospectively included.
