【摘要】Objective: To explore the pattern of solitary lymph node ( SLN ) metastasis and its clinical significance in thoracic esophageal carcinoma ( TEC ) and to explore the theoretical basis for determining the scope of lymphadenectomy in TEC.Methods:The clinicopathologic data of 66 successive patients with solitary positive lymph nodes who underwent radical surgery on TEC were retrospectively amlyzed.The exact location of the metastasized SLN was studied, and the correlation among the location of SLN, the site of primary tumor, and the depth of invasion was investigated.Univariate analyses were used to evaluate the prognostic factors in the patients.Results: In the groups we investigated, the SLN metastasis was most frequently found beside the recurrent nerve and the esophagus as well as around the stomach.There vere 20 cases with skipping nodal metastasis ( 30.3％ ).The SLN metastasis was limited to two or three areas in the patients with superficial TEC, and was widely distributed in those with advanced TEC, including the lymph nodes in the neck, thorax, and abdomen.The postoperative 5-year survival rates were 36.4％ and 42.8 ％ in the group with SLN metastasis and the group without SLN metastasis, respectively, with significant
