To the Editor: In their study of minimally invasive endoscopic staging of suspected lung cancer, Dr Wallace and colleagues1 concluded that endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) has higher sensitivity than traditional transbronchial needle aspiration (TBNA). When evaluating the relative accuracy of a newer technique, it is important to ensure that the standard technique (in this case TBNA) is performed to recognized standards.
