Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a minimally invasive technique for evaluating the mediastinum and staging patients with lung cancer. In the hands of an experienced operator, the procedure is safe and provides excellent sensitivity, specificity, and predictive diagnostic values. In conjunction with endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA), a nearly complete mediastinal evaluation can be performed in a minimally invasive fashion. This strategy results in improved lymph node staging, markedly reduced need for mediastinoscopy, and fewer futile thoracotomies compared with a traditional surgical staging procedure. The procedure is cost effective and provides excellent cytologic specimens that have proven well suited for ancillary testing, such as immunohistochemistry and tumor genotyping. EBUS-TBNA, initially used as a tool to sample the lymp...
