BACKGROUND: Because only approximately 50% of gastric carcinomas are resectable for cure, the authors hypothesized that effective systemic preoperative (neoadjuvant) chemotherapy, aimed at decreasing the size and extent of the primary tumor and eradicating distant microscopic disease, may increase the rate of resectability and have a greater impact on survival than postoperative (adjuvant) treatment alone. In addition, because the peritoneal cavity is the most common site of first recurrence after successful gastric cancer resection, intraperitoneal (IP) chemotherapy seemed a logical choice for postoperative (adjuvant) treatment. METHODS: Fifty-nine patients with invasive primary gastric adenocarcinoma who were deemed resectable for cure entered a clinical trial that called for 2 cycles of protracted infusion 5-fluorouracil with weekly leucovorin and cisplatin chemotherapy followed by surgery. Approximately 3-4 weeks after potentially curative surgery, patients were scheduled to receive two cycles of IP 5-fluoro-2'deoxyuridine and cisplatin. RESULTS: Of the 59 patients studied, 58 (98%) received both cycles of systemic chemotherapy. Fifty-six patients (95%) underwent surgery: 40 patients (71%) had resections intended to cure for Stage 0-IIIB disease, 15 patients (27%) had palliative surgery for Stage IV gastric carcinoma, and one patient died intraoperatively without being staged. Two patients refused surgery, and the remaining patient died of progressive disease prior to surgery. Thirty-one of the 40 patients who underwent curative surgery completed both cycles of postoperative IP therapy; 4 patients received only 1 cycle. Three patients (5%) died secondary to treatment complications. There were two operative deaths, and one patient died of peritonitis associated with Grade 4 granulocytopenia. Nine of the 40 patients (23%) whose carcinomas were resected for cure had recurrent carcinoma. With a median follow-up period now exceeding 45 months, the calculated median survival for the 59 patients entered into the trial is >4 years. CONCLUSIONS: This program of preoperative systemic and postoperative IP chemotherapy has been found to be safe and appears to decrease gastric carcinoma recurrence rates and increase survival compared with historic controls.
