Abstract
The accuracy of morphologic diagnosis from transbronchial fine needle aspirates (TBN), bronchial secretions (BS), bronchial washings (BW), brush biopsy (BB) and forceps biopsy (FB) sampled via a flexible fiberoptic bronchoscope was studied in 60 [human] malignant lung tumors. In visible tumors the best results were obtained with FB (85%) while TBN was positive in 65%. In cases where bronchoscopy only showed secondary signs of tumor, the sensitivity of FB, BB and TBN was higher than that of BW and aspiration of BS. In tumors not visible through the bronchoscope, the diagnostic accuracy of BB, BW and aspiration of BS was higher than that of FB and TBN. In the diagnosis of carcinoma of the lung, the diagnostic accuracy of combining FB and 1 cytologic method (BW) was higher than that of any of the single methods (P < 0.05), while no appreciable increase was achieved by using additional methods.
