Dr. Erik Folch and Dr. Colleen L. Channick join CHEST Podcast Editor, D. Kyle Hogarth, MD, FCCP, for a discussion on whether 50 supervised ultrasound-guided transbronchial needle aspiration procedures are needed to declare competency to assess lung cancer stage. Dr. Folch argues for, noting that although the procedure is safe, the risk of upstaging or downstaging is high in those without more extensive experience. Dr. Channick makes the case that the number 50 is arbitrary and that requiring such a large number of supervised procedures might exclude competent clinicians, thereby denying many patients with lung cancer a vital, non-surgical staging tool
