胸段食管鳞癌喉返神经旁淋巴结转移特点及临床意义

目的：了解胸段食管鳞癌双侧喉返神经旁淋巴结的转移特点及对预后的影响，探讨合理的淋巴结清扫范围。方法：对120例临床资料完整胸段食管鳞癌患者的双侧喉返神经旁淋巴结转移及预后情况进行回顾性分析。结果：120例患者喉返神经旁旁淋巴结转移率为34．2％（41／120），其中左侧20．8％，右侧15．8％。影响喉返神经旁淋巴结转移的因素有肿瘤部位、浸润深度和组织分化程度，而与年龄、性别、肿瘤长度无关。喉返神经旁淋巴结转移的食管癌患者颈部淋巴结转移率为51．2％（21，41），明显高于无喉返神经转移组13．9％（11／79）（P〈0.01）。喉返神经旁淋巴结转移患者术后局部复发为8.3％，同期非三野清扫食管癌手术组3年局部复发率为18％。喉返神经旁淋巴结转移食管癌患者3年生存期为29．3％，明显低于无淋巴结转移患者58．2％（P〈0.05）。结论：所有胸段食管鳞癌均应行双侧喉返神经旁淋巴结清扫，有助于提高根治的彻底性、降低复发率、提高生存率。检测喉返神经淋巴结有助于指导食管癌患者是否行颈淋巴清扫术。

Characteristics of Para-recurrent Laryngeal Nerve Lymph Node Metastases from Thoracic Esophageal Carcinoma and Their Clinical Significance

Objective: To study the characteristics of para-recurrent laryngeal nerve lymph node metastases from thoracic esophageal carcinoma and their influence on patient prognosis and to determine the optimal extent of regional lymph node excision. Methods: The clinical materials of 120 patients who underwent resection of thoracic esophageal carcinoma were retrospectively analyzed. Results: Para-recurrent laryngeal nerve lymph node metastases were found in 41 of these 120 cases (34.2%), with the rate of left and ri...
