Abstract

This study aimed to evaluate the characteristics of lymph node (LN) metastases from thoracic esophageal carcinoma near the recurrent laryngeal nerve and the influence of these metastases on patient prognosis and to determine the reasonable regional LN dissection range. The clinical data from 120 patients who underwent resection for thoracic esophageal carcinoma were analyzed retrospectively. LN metastases near the recurrent laryngeal nerve were detected in 34.2% of the cases, and the metastasis rates in the left and right LNs near the recurrent laryngeal nerve were 20.8 and 15.8%, respectively. The primary tumor site (metastasis rates for esophageal cancer in the upper thoracic segment vs chest or lower thoracic segment: 60.0 vs 40.3 or 15.8%, respectively; P vs well differentiated or differentiated: 56.0 vs 22.0 or 35.6%, respectively; P vs T1 and T2: 42.9 and 50.0% vs 8.33 and 14.3%, respectively; P vs 58.2%; P
