经支气管针吸活检对肺癌的诊断价值

该文对５５例颖为支气管肺癌的肺部病变行纤维支气管镜检查。无可视肿瘤表现者采用经支气管针吸活检术（简称ＴＢＮＡ）检查，并与刷检及术后病理组织细胞学结果进行比较，结果证明５５例病人中ＴＢＮＡ与刷检的正确诊断率分别为９２．７％（５１／５５）和５０．９％（２８／５５）；其中肺癌４１例ＴＢＮＡ和刷检正确诊断率分别为９０．２％（３７／４１）和３４．１％（１４／４１）；ＴＢＮＡ检查明显优于刷检（Ｐ〈０．０１）。

CLINICAL VALUES OF TRANSBRONCHIAL NEEDLE ASPITATION IN THE DIAGNOSIS OF LUNG CANCER

s: Transbronchial needle aspiration (TBNA) biopsy was performed in 55 patients with suspicious ling cancer that had no endoscopically visible tumor. The results of TBNA were compared with that of brushing and operational specimens for cytological examination. In these cases, the correct diagnosis was 92.7% (51/55) for TBNA and 50.9% (28/55) for brushing. In 41 lung cancers, the rate of correct diagnosis was 90.2% for TBNA, 34.1% for brushing. The inspection result of TBNA was better than that of brushing ( P <0.01). When fiberoptic bronchoscopy showed indirect finding, the diagnosis rate of TNBA was 95.7% and that in normal mucosa under bronchoscopy was 83.3%. There was no statistic difference between them ( P >0.05). It is considered that TBNA is useful for all the cases with suspicious lung cancer not only in chest X-ray but also in fiberoptic bronchosocopy. TBNA is a safe, simple, cost-saving and effective skill with important practical and clinical value.
