Postoperative Complications Independently Predict Cancer-Related Survival in Peritoneal Malignancies

Background The authors hypothesized that postoperative complications after cytoreductive surgery–hyperthermic intraperitoneal chemoperfusion (CRS–HIPEC) have a negative impact on perioperative and oncologic outcomes and that the novel Comprehensive Comorbidity Index (CCI) would be a better predictor of such outcomes than the traditional Clavien–Dindo classification (CDC).
