食管癌恶性程度高、预后差。淋巴结转移及阳性淋巴结数量是影响患者预后的重要原因之一,尤其颈淋巴结和喉返神经旁淋巴结是一直研究争议的热点。虽然颈胸腹三野淋巴结清扫术较胸腹两野淋巴结清扫术可以延长患者生存时间并减少复发,但是,该种术式在使患者生存获益的同时也带来了术后高并发症。颈淋巴结是否存在转移直接影响着淋巴结清扫范围,虽然可以通过多种方法诊断颈淋巴结有无转移,但是敏感性及特异性低。喉返神经旁淋巴结被认为是食管癌的前哨淋巴结,用于预测颈淋巴结是否存在转移,然而准确率不超过50%。本文将对目前食管癌颈淋巴转移诊治现状进行综述。
Esophageal cancer has a high degree of malignancy and a poor prognosis. Lymphatic metastasis and the number of positive lymph nodes are one of the important reasons that affect the prognosis of patients. In particular, cervical lymph nodes and para-lingual lymph nodes of the recurrent laryngeal nerve are the hot issues of controversy. Although neck and thoracic and three-field lymphadenectomy compared with chest and abdomen and two-node lymphadenectomy can prolong the survival time of patients and reduce the recurrence, this kind of operation has brought the high postoperative complications while benefiting patients’ survival. The existence of cervical lymph node metastasis directly affects the lymph node dissection range, although there are many ways to diagnose cervical lymph node metastasis, but the sensitivity and specificity low. The recurrent laryngeal para-lymph nodes are considered as sentinel nodes of esophageal cancer and are used to predict the presence or absence of metastases in cervical lymph nodes, however, with an accuracy of no more than 50%. This article will review the current status of diagnosis and treatment of cervical lymph node metastasis of esophageal cancer.
