Topics in Pulmonary Medicine: PDF OnlyTransbronchial Needle Aspiration in Lung CancerSchenk, David A. M.D., F.C.C.R Author Information Dr. Schenk is in private practice in San Antonio, TX. Clinical Pulmonary Medicine: September 1994 - Volume 1 - Issue 5 - p 333-338 Buy Abstract Thirty percent to 40% of patients with lung cancer who undergo a surgical staging procedure have mediastinal lymph node metastasis. Transbronchial needle aspiration (TBNA) staging of patients with lung cancer who manifest paratracheal adenopathy on chest computed tomography (CT) offers the opportunity to pathologically stage patients at the time of diagnostic bronchoscopy. This can be performed safely in an outpatient setting resulting in significant cost savings. In skilled hands TBNA staging can be a sensitive and specific technique. It should be the initial staging procedure in all patients who present with lung cancer and paratracheal adenopathy on chest CT. This review addresses TBNA from a historical perspective, staging/diagnostic utilities, technique, and concerns pertaining to TBNA that have arisen over the past several years. © Williams & Wilkins 1994.
