    Abstract:
    BACKGROUND: The costs for loco-regional treatment of peritoneal carcinomatosis from gastric cancer are not well investigated. The aims of this study were to evaluate the costs and clinical outcome of systemic chemotherapy followed by cytoreductive surgery and intraperitoneal chemotherapy compared to systemic chemotherapy only in patients with peritoneal carcinomatosis from gastric cancer. MATERIAL AND METHODS: Ten patients were scheduled for systemic chemotherapy followed by loco-regional treatment. A reference group of 10 matched control patients treated with systemic chemotherapy only were used and both groups were evaluated with respect to clinical outcome and cost. RESULTS: The mean overall cost in the loco-regional group was $145,700 (range $49,900-$487,800) and $59,300 (range $23,000-$94,800) for the control group. The mean overall survival for the loco-regional group was 17.4 months (range 6.0-34.3), and 11.1 months (range 0.1-24.2) for the systemic chemotherapy only group. The gain in life-years was 0.52 and in quality-adjusted life-years 0.49, leading to incremental cost per life-year and quality-adjusted life-years gained of $166,716 and $175,164, for loco-regional group compared to systemic chemotherapy. DISCUSSION: Treatment of peritoneal carcinomatosis from gastric cancer is costly irrespective of treatment modality. If the survival benefit from adding loco-regional treatment to systemic chemotherapy indicated from this comparison is true, the incremental cost is considered high.
