Overview

Background This randomized phase III study was to evaluate the efficacy and safety of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) for the treatment of peritoneal carcinomatosis (PC) from gastric cancer. Methods Sixty-eight gastric PC patients were randomized into CRS alone ( n  = 34) or CRS + HIPEC ( n  = 34) receiving cisplatin 120 mg and mitomycin C 30 mg each in 6000 ml of normal saline at 43 ± 0.5°C for 60–90 min. The primary end point was overall survival, and the secondary end points were safety profiles. Results Major clinicopathological characteristics were balanced between the 2 groups. The PC index was 2–36 (median 15) in the CRS + HIPEC and 3–23 (median 15) in the CRS groups ( P  = 0.489). The completeness of CRS score (CC 0–1) was 58.8% (20 of 34) in the CRS and 58.8% (20 of 34) in the CRS + HIPEC groups ( P  = 1.000). At a median follow-up of 32 months (7.5–83.5 months), death occurred in 33 of 34 (97.1%) cases in the CRS group and 29 of 34 (85.3%) cases of the CRS + HIPEC group. The median survival was 6.5 months (95% confidence interval 4.8–8.2 months) in CRS and 11.0 months (95% confidence interval 10.0–11.9 months) in the CRS + HIPEC groups ( P  = 0.046). Four patients (11.7%) in the CRS group and 5 (14.7%) patients in the CRS + HIPEC group developed serious adverse events ( P  = 0.839). Multivariate analysis found CRS + HIPEC, synchronous PC, CC 0–1, systemic chemotherapy ≥ 6 cycles, and no serious adverse events were independent predictors for better survival. Conclusions For synchronous gastric PC, CRS + HIPEC with mitomycin C 30 mg and cisplatin 120 mg may improve survival with acceptable morbidity.
