[目的]研究胸段食管癌淋巴结转移规律。[方法]对胸段食管鳞癌切除手术标本150例的淋巴结进行分组制片、光镜观察。[结果]150例病人有淋巴结转移者81例 ,转移率54 0 % ,病变长度≤5cm者 ,转移率为32 3% ,>5cm者为70 6%。淋巴结转移以局部转移多见 ,其次为连续性及跳跃转移 ,淋巴结转移呈向上、向下及双向转移的多方向性为又一特点。[结论]根据淋巴结的转移特性重视术中淋巴结的清扫及术后给以有目的综合治疗 ,可望提高中晚期食管癌的治疗效果。
[Objective] To study the rule of lymph node metastasis in thoracic esophageal cancer. [Method] The lymph nodes in 150 cases of thoracic esophageal squamous cell carcinoma resection were divided into groups and observed with light microscope. [Results] There were 81 cases with lymph node metastasis in 150 cases, the metastasis rate was 54 0%, the length of lesion ≤ 5 cm, the metastasis rate was 32 3%, and those with> 5 cm were 70 6%. Lymphatic metastasis to local metastasis more common, followed by the continuity and jump transfer, lymph node metastasis was up, down and two-way transfer of multi-directional characteristics as another. [Conclusion] It is expected to improve the therapeutic effect of advanced esophageal cancer by paying attention to the dissection of lymph nodes and the postoperative purposeful integrative treatment according to the metastatic characteristics of lymph nodes.
