Abstract

Transbronchial fine needle aspiration(TBNA) is one of the cytologic methods in diagnosing lung cancers. TBNA can be used in cases of hilar, mediastinal or lung masses adjacent to the bronchi. We analyzed and compaired the findings of 27 cases of TBNA and bronchial washing and brushing(BW/BB) in lung cancers confirmed by either biopsy or surgical resection between Jun, 1996 and May, 1997 in Asan Medical Center. They were 18 cases of non-small cell carcinomas(eight squamous cell carcinomas, nine adenocarcinomas, and one large cell undifferentiated carcinoma), eight cases of small cell carcinomas, and one case of metastatic hepatocellular carcinoma. The sensitivity of TBNA was 37%(10/27) and false negative was 63%(17/27). Although the sensitivity of BW/BB w3s 56%(15/27), it was not different statistically from that of TBNA(Chi square, p=0.38). Overall sensitivity of TBNA and BW/BB in this series was 70%(19/27). Forty-seven percent of false negative TBNA(8/17) were positive in BW/BB. The findings suggest that the addition of TBNA to the standard BW/BB increases diagnostic yield in cytologic diagnosis of lung cancer.
