Outcome of patients with negative and unsatisfactory cytologic specimens obtained by endobronchial ultrasound‐guided transbronchial fine‐needle aspiration of mediastinal lymph nodes

Endobronchial ultrasound‐guided transbronchial fine‐needle aspiration (EBUS‐FNA) has gained acceptance as the diagnostic procedure of choice with which to sample hilar and mediastinal lymph nodes (LNs) for diagnosing and staging patients with lung cancer. Studies have shown that EBUS has a high positive predictive value; however, its negative predictive value (NPV) varies significantly. The aim of the current study was to evaluate the clinical outcome surrounding negative and nondiagnostic EBUS‐FNA of mediastinal LNs.
