Background: The peritoneal carcinomatosis (PC) due to gastrointestinal or gynecological cancer has increased its incidence. It has a worse prognosis compared to other sites of metastasis. The peritoneal carcinomatosis index (PCI) establishes overall survival in patients with gastrointestinal or gynecological tumors and carcinomatosis. Objective: To evaluate the relationship of PCI to overall survival (OS) and recurrence-free survival (RFS) in patients treated with cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC). Method:A descriptive, retrolective study of 80 charts of patients with CP was conducted.We included patients with colon, ovarian, appendicular, pseudomyxoma and gastric tumors with CP treated with CRS plus HIPEC.The OS and RFS were determined according to the type of adenocarcinoma and the degree of differentiation.The OS and RFS were determined in months in patients with PCI > 15 PCI as well as in patients with PCI 70 months, compared to patients with gastric tumors (4 months).Conclusions: The PCI and histology are predictors of OS.Patients with ovarian tumors and PCI < 15 have higher OS, similar to pseudomyxomas.RFS was also higher in patients with PCI < 15.
