Cyto-Chip: Cytoreductive Surgery Versus Cytoreductive Surgery And Hyperthermic Intraperitoneal Chemotherapy For Gastric Cancer With Peritoneal Metastasis: A Propensity-Score Analysis From Big Renape And Fregat Working Groups.
JOURNAL OF CLINICAL ONCOLOGY(2018)
摘要
8Background: Gastric cancer with peritoneal carcinomatosis (PC) is considered by most as an end-stage disease. Poor outcomes are achieved with palliative chemotherapy. Aggressive combination of cytroreductive surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) are still debated in this indication. Purpose: to assess the impact of HIPEC on survival and postoperative outcomes after complete CRS compared with CRS alone (CRSa) Methods: Data from 277 consecutive patients treated for gastric cancer with PC in 19 French centers from 1989 to 2014 were collected. 180 patients who underwent CRS and HIPEC were compared to 97 treated by CRSa. Extension of PC was assessed by the Peritoneal Cancer Index (PCI). Only patients treated by complete CRS were included (CC-0 or CC-1). To assess the effect of HIPEC and to account for confounding factors, a Cox proportional hazards regression model with inverse probability of treatment weighting (IPTW) based on propensity score was used. Multivariate models and s...
