Non-resectable gastric cancer is an incurable disease. Systemic chemotherapy confers prolongation of survival and improvement of quality of life. Regimens containing cisplatin and 5-fluorouracil (5-FU) are widely adopted in the world. A P-HDFL regimen, based primarily on weekly 24-hour infusion of cisplatin and high-dose 5-FU and leucovorin, is commonly used in Taiwan for patients with advanced gastric cancer; the overall response rate is around 60% (45%-76%, 95% C.I.), and the patients' compliance is excellent.
