Background: This work was to evaluate cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for advanced gastric cancer (GC).
Methods: CRS and HIPEC were performed on 28 GC patients with peritoneal carcinomatosis (PC) and/or malignant ascites, with survival and perioperative safety as study endpoints.
Results: A total of 30 CRS and HIPEC procedures were performed. Cytoreduction scores ratings (CCR) were CCR-0 in 11 (39.2%), CCR-1 in 6 (21.4%), CCR-2 in 8 (28.8%), and CCR-3 in 3 (10.6%) cases. The 6-, 12-, 18-, and 24-month survival rates were 75%, 50%, 43%, and 43%, respectively. The median survivals of patients with PCI <or=20 and high PCI >20 were 27.7 months (95% CI 15.2-40.3 months) and 6.4 months (95% CI 3.8-8.9 months) (P = 0.000). The estimated median survival for patients with CCR-0, CCR-1, and CCR-2 and 3 were 43.4 months (95% CI, 26.9-59.9 months), 9.5 months (95% CI 6.4-12.6 months), and 7.5 months (95% CI 3.0-13.6 months) (P = 0.001, CCR0 vs. CCR1-3). No perioperative death but 1 (3.6%) serious adverse event occurred.
Conclusions: CRS plus HIPEC could offer survival advantage for selected GC patients with PC and/or ascites, with acceptable safety profile.
