食管癌右喉返神经旁淋巴结转移的相关因素研究

Related factors of right recurrent nerve nodal involvement in esophageal cancer

目的 探讨食管癌右侧喉返神经旁淋巴结转移的相关因素.方法 回顾性分析280例行右侧喉返神经旁淋巴结清扫的食管癌患者的临床病理学资料.应用χ^2检验进行单因素分析,应用Logistic回归分析进行多因素分析.结果 280例食管癌患者中,右侧喉返神经旁淋巴结转移76例,转移率为27.1%.右侧喉返神经旁淋巴结清扫979枚,转移118枚,转移度为12.1%.Logistic回归分析结果显示,肿瘤分级、淋巴结转移数、脉管瘤栓、胸部淋巴结转移数、腹部淋巴结转移数、隆突下淋巴结转移以及食管周围淋巴结转移是影响右侧喉返神经旁淋巴结转移的独立因素.结论 右侧喉返神经旁淋巴结清扫应该参照淋巴结转移的影响因素,合理地进行清扫.

Objective To study the related factors of right recurrent nerve nodal involvement in esophageal cancer. Methods 280 patients with thoracic esophageal cancer received esophagectomy and right recurrent nerve node dissection. The clinicopathological data were analyzed retrospectively. Univariate data were analyzed by chi-square test, and multivariate data were analyzed by logistic regression. Results The right recurrent nerve nodal metastasis was found in 76 cases （27.1% , 76/280）. In the 979 excised right recurrent nerve nodes, metastases were found in 118 nodes （12.1%）. The tumor staging, the total number of involved lymph nodes, vascular invasion, the number of lymph node metastases in the thorax, the number of lymph node metastasis in the abdomen, subcarinal node metastasis, and peri-esophageal lymph node metastasis were independent risk factors of right recurrent nerve node metastasis in esophageal carcinoma.Conclusion Right recurrent nerve lymph nodes should be dissected in those patients with high risk factors of lymph node metastasis in thoracic esophageal carcinoma.
