OBJECTIVE: To evaluate the diagnostic yield and the safety of endobronchial ultrasound-guided transbronchial needle biopsy (EBUS-TBNA) in mediastinal and hilar lymph nodes and lung tumors.
METHODS: EBUS-TBNA was performed in 70 patients with thoracic masses or mediastinal-hilar lymphoadenopathy proved by CT scan.
RESULTS: From July 2009 to January 2010, 70 patients were included in the study. EBUS-guided TBNA was performed to obtain samples from mediastinal and hilar lymph nodes (120 stations) and lung tumors (11 masses). In 46 cases of newly diagnosed lung cancer, 44 were confirmed by EBUS-TBNA without on site cytology assistance, with 2 false negative cases. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of EBUS-TBNA in the diagnosis of lung cancer were 96%, 100%, 100%, 92% and 97% respectively. Non-caseous granuloma formed by epithelioid cells was found in EBUS-TBNA histological specimen from 5 out of 10 patients with clinically diagnosed sarcoidosis. TBNA cytological smear showed acid-fast bacilli and histology of the lymph node demonstrated coagulatory necrosis from 1 out of 4 tuberculous cases. The procedure was uneventful, and there were no complications.
CONCLUSION: EBUS-TBNA is an effective and safe method for the diagnosis of bronchogenic carcinoma and unknown mediastinal-hilar lymphadenopathy.
