对我院病理科１９８７年１１月－１９９３年１２月收检的３１６例胸段食管癌（ＥＣａ）根治术标本进行分析。全组淋巴结转移（ＬＮＭ）率为４５．６％。胸上段ＥＣａ、胸中段ＥＣａ、ＮＴ段ＥＣａ的ＬＮＭ率分别为２９．２％、４４．３％、５４．８％。ＬＮＭ程度与肿瘤长度、浸润深度及组织学类型表明的恶性程度呈正相关。胸上段ＥＣａ主要发生上行转移；胸中段ＥＣａ多发生双向转移；而胸下段ＥＣａ主要发生下行转移，胸中下段ＥＣａ转移至其它站的淋巴结较胸上段ＥＣａ多。／／关键词
The 316 cases of thoracic esophageal cancer (ECa) radical mastectomy specimens from our department of pathology from November 1987 to December 1993 were analyzed. The overall lymph node metastasis (LNM) rate was 45.6%. The LNM rates of ECa in the upper chest, ECa in the mid thoracic ECA, and ECa in the NT segment were 29.2%, 44.3%, and 54.8%, respectively. The degree of LNM was positively correlated with the length of the tumor, depth of invasion, and histological type of malignancy. In the upper thoracic ECa, there was an upward shift; in the middle thoracic ECa, there was a two-way shift; in the lower thoracic ECa, there was a major downward shift; in the lower thoracic ECa, more lymph nodes were transferred to other stations than in the upper thoracic ECa. //Key words
