Key Points Question What are the morbidity and mortality of cytoreductive surgery combined with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) compared with other major oncologic surgical procedures? Findings In this cohort study of 1822 patients who received CRS/HIPEC compared with patients who received other high-risk surgical oncology procedures, overall 30-day mortality was lower in CRS/HIPEC (1.1%) compared with pancreaticoduodenectomy (2.5%), right lobe hepatectomy (2.9%), esophagectomy (3.0%), and trisegmental hepatectomy (3.9%). Meaning Comparative analysis revealed CRS/HIPEC to be safe across the spectrum of National Surgical Quality Improvement Project safety metrics when compared with oncologic procedures with similar inherent risk.
