1990年1月至1995年12月间，行近侧胃大部分切除、食管一胃主动脉弓下吻合术治疗贲门癌396例，切缘癌残留率15．7％（62／396），以食管侧为主。认为贲门癌手术切除长度（切缘至瘤缘长度）不足是导致切缘癌残留的主要原因，切除长度5cm以上，能显著降低切缘癌残留率；切缘癌残留还与肿瘤的生长方式、组织学类型和病期有密切关系，并降低生存率。同时对预防措施进行讨论。
Between January 1990 and December 1995, 396 patients with cardiac cancer were treated with proximal gastrectomy and esophageal-gastric aortic arch anastomosis. The residual margin of cancer at the margin of resection was 15.7% (62/396). Mainly. It is considered that the length of surgical resection of the cardiac cancer (incisional margin to the length of the tumor margin) is the main cause of marginal resection of the cancer. The resection length of more than 5 cm can significantly reduce the residual margin of the resection margin; the resection margin and the tumor growth pattern, The type of histology is closely related to the stage of disease and reduces the survival rate. At the same time, discuss preventive measures.
