EBUS-TBNA is primarily used in diagnosing and staging lung cancer, but additional applications exist, including evaluation of unexplained mediastinal lymphadenopathy, suspected granulomatous diseases (i.e., sarcoidosis) and lymphoproliferative disorders (2-5). The most recent guidelines from the American College of Chest Physicians (ACCP) and European Society of Thoracic Surgeons (ESTS) recommend EBUS-TBNA as the first-line test for mediastinal staging in non-small cell lung cancer (NSCLC) (1,6) %U http://jtd.amegroups.com/article/view/28408/html
