Abstract
A study was conducted to determine the bronchoscopic and chest roentgenographic findings associated with a positive TBNA. One hundred fifty-seven of 465 patients who were diagnosed for the first time as having carcinoma of the lung had a positive aspirate. Bronchoscopic findings associated with a positive TBNA of N2 nodes were carinal widening and endobronchial disease, especially of the right upper lobe. Mediastinal adenopathy noted on chest roentgenograms and subcarinal nodes on CAT scans were associated with a positive aspirate as well. In 34 of 465 patients, TBNA was the only means of establishing the diagnosis of pulmonary malignancy. A useful, simple and safe procedure, TBNA can be used to stage the mediastinum in patients with lung cancer and is most likely to be positive with endobronchial and nodal disease. It can also facilitate therapeutic decision-making in patients whose surgical candidacy is marginal.
