title: [Comparison the standard therapies of gastric cancer in Japan with those in the West].
abstract: We compare Japanese practice guidelines for gastric cancer with those published from National Comprehensive Cancer Network (NCCN). In surgery, D1 dissection is referred as standard in NCCN, because mortality of D2 dissection was higher than that of D1 (10% vs 4%). However, Japanese investigators show lower mortality rate (0.8%) of D2 dissection, so D2 dissection is referred as standard for stage II/III disease in Japan. Chemoradiotherapy is chosen for residual disease or unresectable disease (M0) in NCCN, but these categories are required D2 dissection or extensive resection in Japan. Because Japanese D2 dissection has better optimized survival rate than chemoradiotherapy,chemoradiotherapy will not be introduced to Japan. In chemotherapy, ECF or taxanes (e.g., DCF) is referred as a prior therapy in NCCN, but 5-FU contain regimen (e.g., FP, LV/5-FU, S-1, or S-1/CDDP) as a prior therapy in Japan. Both ECF and DCF are too toxic regimen for Japanese patient to use. Difference of race seem to be relevant to difference of mortality or toxicities. From the results of ACTS-GC, we think that adjuvant chemotherapy is referred as standard in Japan. Future, results of JCOG 9912 and many other trials will be coming soon, so the guidelines will be changed.
