对877例具有临床和X线检查指征的患者进行了纤支镜检查,其中177例获得组织学或细胞学诊断,均确诊为肺癌。肺癌的确诊率为20%。本文对纤支镜提高肺癌的确诊率,纤支镜直视所见与细胞学类型的关系以及细胞学类型与部位关系进行了探讨。 Fifty-seven patients with clinical and radiographic indications underwent bronchoscopy, of whom 177 were diagnosed histologically or cytologically and were diagnosed with lung cancer. The diagnosis rate for lung cancer is 20%. In this paper, the diagnostic rate of bronchoscopy in the diagnosis of lung cancer, the relationship between the type of bronchoscopy and the type of cytology, and the relationship between the type of cytology and its location were discussed.
