Abstract
OBJECTIVE: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new method for the diagnosis and staging of lung disease, and its use is increasing worldwide. It has been used as a means of diagnosing lung cancer in its initial stages, and there are data supporting its use for the diagnosis of benign lung disease. The aim of this study was to share our experience with EBUS-TBNA and discuss its diagnostic value.Entities:

Figure 2.ROC curve analysis: when a lymph node size (short-axis diameter) cut-off value of 16.5 mm was applied, the sensitivity and specificity of endobronchial ultrasound (for a diagnosis of granulomatous disease or malignancy) were 76% and 60%, respectively. Diagonal segments are produced by ties.
