从１９８５年至１９９０年６月，作者共收集２３３例经外科手术切除之胃癌病例，发现切端癌残留４０例，切端癌阳性率为１７．１％。切端癌残留率与肿瘤发生部位，肿瘤浸润深度，区域淋巴结转移，病理类型、临床病理分期有关。切端癌残留不会影响吻合口瘘发生率及吻合口复发率。切端阳性组与切端阴性组 ３年生存率分别为４０％、５８．５％（Ｐ＼０．０５）。Ⅲ期胃癌切端癌残留患者，化疗组、无化疗组３年生存率分别为６９．２％、１７．６％（Ｐ＼０．０１）。说明Ⅲ期胃癌术后切端癌残留通过化疗可提高生存率。
From 1985 to June 1990, the authors collected a total of 233 cases of gastric cancer that had been surgically resected and found that 40 cases had residual cancer of the cut end. The positive rate of cut-end cancer was 17.1%. The residual rate of cancer at the cut end was related to the location of the tumor, depth of tumor invasion, regional lymph node metastasis, pathological type, and clinical pathological stage. Cholesocarcinoma residuals do not affect the incidence of anastomotic leakage and the recurrence rate of anastomoses. The 3-year survival rates of the positive group and the negative group were 40% and 58.5%, respectively (P0.05). In patients with stage III gastric cancer residual cancer, the 3-year survival rates in the chemotherapy and non-chemotherapy groups were 69.2% and 17.6%, respectively (P0.01). This shows that the residual cancer in the excision of stage III gastric cancer can improve the survival rate through chemotherapy.
