1526例胸段食管癌及贲门癌淋巴结转移状况分析(附1996~2004年河北医科大学第四医院随机抽样报告)

Lymph Node Metastases from Carcinoma of the Thoracic Esophagus and Cardia: a Random Sampling Report of 1,526 cases

  • 摘要: 目的 :本研究拟通过分析胸段食管癌及贲门癌淋巴结转移状况及规律,探究影响淋巴结转移的因素。 方法 :随机抽取1996年1月~2004年12月河北医科大学第四医院收治的胸段食管癌及贲门癌手术病例1526例,建立患者临床资料Access数据库。选取年龄、肿瘤部位、肿瘤长度、病理类型、浸润深度、脉管瘤栓、周围器官受侵和标本残端8个临床特征因素,对每一因素进行分层,分析其与淋巴结转移之间的相关性。统计分析采用SPSS13.0软件包进行分析。 结果 :胸段食管癌淋巴结转移部位包括胸腔和腹腔;胸上段食管癌主要向颈部和胸腔淋巴结转移;胸中段食管癌淋巴结转移呈上下双向;胸下段食管癌主要向食管旁淋巴结、贲门旁淋巴结和胃左动脉淋巴结转移,其转移率和转移度均显著高于胸上段和胸中段食管癌(P<0.0125)。贲门癌腹腔淋巴结转移程度显著高于胸段食管癌。贲门癌组贲门旁和胃左动脉淋巴结的转移率和转移度显著高于食管癌组(P<0.05);贲门癌胸腔食管旁淋巴结也易发生转移,转移程度与胸段食管癌相似。食管旁淋巴结的转移率和转移度在贲门癌和胸段食管癌两组之间无显著性差异(P>0.05)。多因素Logistic回归分析:肿瘤长度、浸润深度、脉管瘤栓、标本残端情况对淋巴结转移均有显著性影响(P<0.05)。 结论 :胸上段食管癌主要向颈部及胸腔淋巴结转移,胸中段食管癌淋巴结转移呈上下双向转移,胸下段食管癌主要向胸腔、腹腔淋巴结转移,贲门癌淋巴结转移主要在腹腔,食管旁淋巴结也易出现转移。胸段食管癌颈部淋巴结清扫应引起重视,胃左动脉淋巴结同样是清扫中最需要关注的,贲门癌食管旁淋巴结的清扫不容忽视。随着肿瘤长度、浸润深度的增加以及脉管瘤栓和残端癌细胞的出现,发生淋巴结转移的危险性显著增加。

     

    Abstract: Objective : To observe the status of lymph node metastases from carcinoma of the esophagus and cardia and to analyze the related factors. Methods : Clinical data from 1,526 patients with carcinoma of the thoracic esophagus and cardia seen in our hospital between January 1996 and December 2004 were analyzed.Fac-tors including age, tumor location, tumor diameter, pathological classification, depth of tumor invasion, vascu-lar tumor embolus, involvement of other organs, and the status of tumor residues were stratified and analyzed with SPSS13.0 software. Results : Carcinoma of the upper thoracic esophagus mainly metastasized to tho-racic and cervical lymph nodes; carcinoma of the middle-third thoracic esophagus metastasized bidirectional-ly; and carcinoma of the lower-third thoracic esophagus mainly metastasized to the lymph nodes of the lateral esophagus, lateral cardia and gastric artery.The rate of metastasis to lymph nodes of lower-third esophageal cancer was higher than that of upper and middle-third esophageal cancer ( P <0.05).Compared with thoracic esophageal cancer, cardiac carcinoma had a higher rate of metastases to lymph nodes in the abdominal cavi-ty, lateral cardia and gastric artery ( P <0.05).No statistical significance was found in the number of metastases to the lateral esophageal lymph nodes between cardiac carcinoma and thoracic esophageal carcinoma ( P > 0.05).Results of Multiple Factors Logistic Regression Analysis showed that tumor diameter, depth of tumor in-vasion, vascular tumor embolus and the status of carcinoma residues influenced the lymphatic metastasis. Conclusion : Tumor diameter, depth of tumor invasion, vascular tumor embolus and the status of tumor residues are correlated to lymphatic metastases.
