Abstract
Objective To evaluate correlation factors of cervical lymph nodes metastasis in thoracic esophageal carcinoma.Methods Local-regional metastasis of lymph node for 126 cases with esophageal squamous cell cancer after surgery from 2004 to 2009 were reviewed.Risk factors of cervical lymph nodes metastasis were examined by multiple Logistic regression analysis.Results In 126 cases,supraclavicular lymph node metastasis rate was 43.7％ (55/126).By logistic regression,none of the primary site,T stage,N stage,histological grade,lymph node metastasis rate,lymph node metastasis degree and number of lymph nodes metastatic field was not the high risk of cervical lymph nodes metastasis.In addition,multivariate analysis found that lymph node metastasis in mediastinum region 1 was high risk factor for lymph node metastasis of region 1 ( x2 =12.14,9.27,P =0.000,0.002),lymph node metastasis in region Ⅲ and region 2 were high risk factors for lymph node metastasis of region Ⅱa ( x2 =14.56,8.27,8.02,3.93,P =0.000,0.004,0.005,0.047 ).Conclusion Mediastinal para-recurrent nerve lymph node metastasis is a significant predictor for cervical lymph nodes metastasis. Key words: Esophageal neoplasms/surgery; Neoplasms meatstasis,neck lymph nodes; Neoplasms metastasis,para-recurrent nerve lymph node
