Background: Endobronchial ultrasound-guided transbronchial aspiration (EBUSTBNA) has the potential to improve nodal diagnosis and staging in non-small cell lung cancer (NSCLC). This study was performed to explore the roles of EBUS-TBNA in NSCLC. Methods: From2007 to 2009, 164 NSCLC patientswere examined by EBUS-TBNA. The patients were divided into a diagnosis group (n = 64) and a staging group (n = 100). Results: For all patients, the diagnostic sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were 92.3%, 100%, 100%, 88.2%, and 95.1%, respectively. In the diagnosis group, the diagnostic sensitivity, specificity, PPV, NPV, and accuracy were 89.7%, 100%, 100%, 86.2%, and 94.4%, respectively. Thirty five patients (54.7%) positive for malignancy as determined by EBUS-TBNA avoided surgery. In the staging group, the diagnostic sensitivity, specificity,PPV,NPV, accuracy, and surgery avoidance rate were 93.8%, 100%, 100%, 89.7%, 96%, and 61%, respectively. Conclusions: EBUS-TBNA is a feasible and effective tool for NSCLC diagnosis and staging that also reduces surgery rates. Patients with NSCLC should initially undergo the less invasive EBUS-TBNA procedure for diagnosis and staging of NSCLC.However, negative findingsmust be confirmed by surgery.
