The Japanese Gastric Cancer Association (JGCA) started a new nationwide gastric cancer registry in 2008. Approximately 50 data items, including surgical procedures, pathological diagnoses, and survival outcomes, for 12004 patients with primary gastric cancer treated in 2001 were collected retrospectively from 187 participating hospitals. Data were entered into the JGCA database according to the JGCA Classification of gastric carcinoma, 13th edition and the International Union Against Cancer (UICC) TNM Classification of malignant tumors, 5th edition by using an electronic data collecting system. Finally, data of 11261 patients with gastric resection were analyzed. The 5-year follow-up rate was 83.5%. The direct death rate was 0.6%. TNM 5-year survival rates (5YSRs)/JGCA 5YSRs were 91.8/91.9% for stage IA, 84.6/85.1% for stage IB, 70.5/73.1% for stage II, 46.6/51.0% for stage IIIA, 29.9/33.4% for stage IIIB, and 16.6/15.8% for stage IV. The proportion of patients more than 80 years old was 7.0%, and their 5YSR was 48.7%. Compared to the JGCA archived data, though the follow-up rate needs to be improved, these data suggest that the postoperative results of patients with primary gastric carcinoma have improved in those with advanced disease and in the aged population in Japan.
日本胃癌协会（JGCA）于 2008 年启动了一项新的全国性胃癌登记。从 187 家参与医院回顾性收集了 2001 年治疗的 12004 例原发性胃癌患者的大约 50 项数据，包括手术程序、病理诊断和生存结果。根据 JGCA 胃癌分类第 13 版和国际抗癌联盟（UICC）恶性肿瘤 TNM 分类第 5 版，使用电子数据收集系统将数据输入 JGCA 数据库。最后，分析了 11261 例胃切除术患者的数据。5 年随访率为 83.5%。直接死亡率为 0.6%。TNM 5 年生存率（5YSR）/JGCA 5YSR 分别为 IA 期 91.8%/91.9%、IB 期 84.6%/85.1%、II 期 70.5%/73.1%、IIIA 期 46.6%/51.0%、IIIB 期 29.9%/33.4%和 IV 期 16.6%/15.8%。80 岁以上患者的比例为 7.0%，其 5YSR 为 48.7%。与 JGCA 存档数据相比，尽管需要提高随访率，但这些数据表明，日本晚期和老年人群中原发性胃癌患者的术后结果有所改善。
