超声内镜引导下支气管针吸活检在肺癌及纵隔病变中的诊断价值

Objective To investigate the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in lung carcinoma and mediastinal lesions.Methods From Jan.,2015 to Dec.,2015,368 patients with hilar and/or mediastinal lymphadenopathy or mass outside the airways by CT scan or PET/CT in Department of Pulmonary Medicine,Zhongshan Hospital,Fudan University were enrolled and recieved EBUS-TBNA examination.All of their clinical data were collected.Results Retrospective analysis was performed in the 368 patients.In the 252 patients diagnosed as malignancy,232 patients were diagnosed by EBUS-TBNA,while the other 116 patients were diagnosed as benign disease.The diagnostic concordance rate was 92.9%.A total of 387 lymph nodes and 56 masses outside the airways were found among the 368 patients received EBUS-TBNA procedure.The sensitivity and specificity of EBUS-TBNA were 92.1% and 100%,respectively.Conclusions EBUS-TBNA is an effective and safe method with high specificity and sensitivity in diagnosis of unknown hilar and/or mediastinal lymphadenopathy,mediastinal mass as well as lymph node staging in lung cancer patients.
