The clinical efficacy of chemotherapy for patients with advanced gastric cancer has not been established. We investigated in a phase II study the combination chemotherapy of low dose 5-fluorouracil (5-FU) and cisplatin (low dose FP) to evaluate its clinical efficacy in terms of response, quality of life and survival in 43 gastric cancer patients including 29 advanced and 14 recurrent cases. The administration of 5-FU was done by continuous intravenous infusion for 28 consecutive days with a dose of 250 mg/m2, while the administration of cisplatin was done by 1-h intravenous drip-infusion for 5 consecutive days and 2-day intervals per week with a dose of 3.5 mg/m2, that was repeated for 4 weeks in one cycle. The response rate in advanced cases was 48.3%, evaluated in 14 cases of partial response (PR), whereas its response rate in recurrent cases was 35.7%, evaluated in 5 cases of PR. The most effective lesions for low dose FP chemotherapy were primary lesion and lymph node metastasis. The quality of life assessed by performance status and oral intake was improved in 13.8% and 37.9% of advanced cases, and 21.4% and 28.6% of recurrent cases, respectively, as compared to those of pretreatment. The median survival time and 1-year survival rate were 6 months, 21.6% in advanced cases and 10 months, 28.8% in recurrent cases, respectively. The major adverse effect was observed in gastrointestinal toxicity and leukopenia, and the all toxicities were less than grade 2, that were controllable during the treatment. These results indicated that the combination chemotherapy of low dose administration of 5-FU and cisplatin might have therapeutic efficacy in tumor response and offer improvement in quality of life in patients with advanced and recurrent gastric cancer.
