近年来早期胃癌(EGC)逐渐增加,本文试对其合理的外科治疗及有关问题作粗浅的综述。早期胃癌的定义:即浅表性或粘膜内癌可描述为局限于粘膜层(M)或粘膜下层(SM),而未形成一个块状物的癌,与有无淋巴结转移无关。1970年以后日本报道在切除的标本中EGC占30～40%,1978年高木等报道占同期胃癌根治手术中的37.9%,即三例根治术中即有一例,1980年报道EGC534例占同期胃癌1,229例之43.5%,这说明EGC有所增加。早期胃癌的淋巴结转移
In recent years, early gastric cancer (EGC) has gradually increased. This article tries to provide a summary of its reasonable surgical treatment and related issues. The definition of early gastric cancer: Superficial or intramucosal cancer can be described as being confined to the mucosal layer (M) or submucosa (SM), whereas a cancer that does not form a mass is not associated with lymph node metastasis. After 1970, Japan reported that EGC accounted for 30 to 40% of resected specimens. Takagi et al reported in 1978 that it accounted for 37.9% of radical mastectomy in the same period, that is, one case of radical mastectomy in three cases. In 1980, 534 cases of EGC were diagnosed as gastric cancer in the same period. Of the 1,229 cases, 43.5% indicate that EGC has increased. Lymph node metastasis in early gastric cancer
