RESUMO
UNLABELLED: Feasibility and efficacy of S-1 and cisplatin followed by surgery was evaluated, and factors contributing to survival benefit were analyzed. PATIENTS AND METHODS: In total, 120 consecutive patients with highly advanced gastric cancer were treated with S-1 (80 mg/m(2) for 21 consecutive days) and cisplatin (50 mg/m(2) on day 8). RESULTS: The response rate was 62.5% overall, and 75.7% for these with metastatic lymph nodes. Grade 3/4 adverse events were less than 10%. The median survival time was 41.9 months among 93 patients whose primary lesion was resected. Liver metastasis, R2 resection, poor performance status and lack of response were identified as independent risk factors by a multivariate analysis. CONCLUSION: Preoperative chemotherapy with S-1 and cisplatin was effective. The results show the need for different approaches in the treatment of patients with metastases and these without.
