From January 1965 until December 1982, early gastric carcinoma cases comprised 765 of 2,235 curative resections and 17 of 620 noncurative resections, for a total of 782 cases. The rate of lymph node metastasis for mucosal carcinoma was 1.2%, and that for submucosal carcinoma was 18.2%. Gastrectomy with removal of the second-group lymph node proved adequate for submucosal carcinoma. The five-year survival rates for mucosal carcinoma and for submucosal carcinoma were 94.9% and 93.6% respectively. The rate of recurrence of mucosal carcinoma was 0.6%, against 2.5% for submucosal carcinoma. Adjuvant chemotherapy is necessary to obtain improved surgical results for submucosal carcinoma. Important factors affecting the recurrence of submucosal carcinoma are lymph node metastasis, macroscopic findings and histological findings. Ten out of 17 cases of noncurative resection had cancer cells at the resection margin, caused by inadequate resection.
从1965年1月至1982年12月，早期胃癌病例在2235例根治性切除术中占765例，在620例非根治性切除术中占17例，共计782例。黏膜癌的淋巴结转移率为1.2%，黏膜下癌的淋巴结转移率为18.2%。对于黏膜下癌，切除第二组淋巴结的胃切除术被证明是足够的。黏膜癌和黏膜下癌的五年生存率分别为94.9%和93.6%。黏膜癌的复发率为0.6%，而黏膜下癌的复发率为2.5%。对于黏膜下癌，需要辅助化疗以提高手术效果。影响黏膜下癌复发的重要因素是淋巴结转移、宏观表现和组织学表现。17例非根治性切除病例中有10例在切除边缘有癌细胞，这是由于切除不充分所致。
