title: [The diagnostic value of transbronchial needle aspiration in patients with extrabronchial bronchogenic carcinoma].
abstract: Tissue pathologic and cytologic examination of 47 cases with suggestive extrabronchial bronchogenic carcinoma using the four technics of transbronchial needle aspiration (TBNA), bronchial biopsy, brushing and washing through the fiberoptic bronchoscopy were reported. For any one case, any one or more of the above said technic showed positivity will be regarded as positive case. The results showed that the total positive rate was 82.9%. The diagnostic rate of using TBNA alone was 68.1% that of bronchial biopsy 63.8% and bronchial brushing 70.2% (P > 0.05), but obviously higher than the bronchial washing (34.0%) (P < 0.05). Thus the deficiency of any one above said technic will be complemented by one of the other technics. The results also showed that TBNA is especially suitable for use in the squamous and small cell types of lung cancer. Complications of pneumothorax or bleeding were not found with the TBNA technic. We, therefore, recognize that the TBNA is one of a high positive rate, easily performed and with few complications diagnostic technic for extrabronchial bronchogenic carcinoma, and it should be recommended for clinical application.
