N2 - Background: Current national guidelines do not include hyperthermic intraperitoneal chemoperfusion (HIPEC) as treatment for gastric cancer, and there are no completed clinical trials of cytoreduction, gastrectomy, and HIPEC from the US. Methods: Patients with gastric adenocarcinoma and positive peritoneal cytology or carcinomatosis who had completed systemic chemotherapy and laparoscopic HIPEC underwent cytoreduction, gastrectomy, and HIPEC with 30 mg mitomycin C and 200 mg cisplatin. The primary endpoint was overall survival (OS), with a secondary endpoint of postoperative complications (NCT02891447). Results: We enrolled 20 patients from September 2016 to March 2019. Six patients had positive cytology only and 14 had carcinomatosis. All patients were treated with systemic chemotherapy with a median of eight cycles (range 5–11 cycles) and at least one laparoscopic HIPEC. The median peritoneal carcinomatosis index at cytoreduction/gastrectomy/HIPEC was 2 (range 0–13). After surgery, the 90-day morbidity and mortality rates were 70% and 0%, respectively. Median length of hospital stay was 13 days (range 7–23 days); median follow-up was 33.5 months; median OS from the date of diagnosis of metastatic disease was 24.2 months; and median OS from the date of cytoreduction, gastrectomy, and HIPEC was 16.1 months. 1-, 2-, and 3-year OS rates from the diagnosis of metastatic disease were 90%, 50%, and 28%, respectively. Conclusions: Survival rates for patients with gastric adenocarcinoma and peritoneal disease treated with cytoreduction, gastrectomy, and HIPEC are encouraging; our early results are similar to those of recent prospective registry studies. Multi-institutional and cooperative group trials should be supported to confirm survival and safety outcomes.
