RESUMO
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.
