* * Conclusions: Adjuvant chemotherapy with S-1 for gastric cancer is feasible and effective. This regimen can be the standard treatment for stage II/III gastric cancer pts after curative D2 dissection. 一种新型口服氟尿嘧啶类药物: Tegafur (5FU前体药物) Gimeracil (通过抑制 DPD酶阻断5FU降解) 吉美嘧啶 Oteracil (Oxo乳清酸磷酸核糖转移酶的竞争性抑制剂使5FU的胃肠道毒性减小) 奥替拉西 ORR of 26-49% in various phase II trials in gastric cancer1 * Figure 1. Kaplan-Meier Estimates of Overall Survival and Relapse-free Survival. Three years after randomization, the rate of overall survival was 80.1% in the S-1 group and 70.1% in the surgery-only group (Panel A), and the rate of relapse-free survival was 72.2% in the S-1 group and 59.6% in the surgery-only group (Panel B). The hazard ratio for death in the S-1 group as compared with the surgery-only group was 0.68 (95% confidence interval, 0.52 to 0.87; P=0.003). The hazard ratio for relapse in the S-1 group was 0.62 (95% confidence interval, 0.50 to 0.77; P﹤0.001) * ARTIST study design. Lee et al. ASCO GI 2009 * In conclusion: XP was tolerable in the post-operative setting. The addition of radiotherapy to adjuvant XP chemotherapy did not significantly increase toxicity. The majority of patients completed the planned post-operative treatment. The results on disease-free survival will be available in 2011. Lee et al.
