研究目的探讨中心型及周围型肺癌的诊断方法。研究背景国内对中心型及周围型肺癌纤支镜检查阳性诊断率结果报道差别较大。我们以诊断了1288例肺癌，进一步分析纤支镜检查在中心型及周围型肺癌诊断中的价值。方法全部病例根据纤夫镜活俭及刷检、痰细胞学、胸水细胞学、肺穿刺活检及肺叶切除病理学检查结果确诊。结果纤支镜检查总阳性确诊率为64.36％，中心型及周围型肺癌阳性确诊率分别为79.90％和40.80％。结论纤支镜检查中对中心型肺癌的阳性确诊率较高，但对周围型肺癌的阳性确诊率较低。
The purpose of the study was to investigate the diagnosis of central and peripheral lung cancer. Research Background Domestic reports on the positive diagnosis rate of bronchoscopy in central and peripheral lung cancers are quite different. We diagnosed 1288 lung cancers and further analyzed the value of bronchoscopy in the diagnosis of central and peripheral lung cancer. Methods All cases were diagnosed according to the results of fiberoptic fluoroscopy and brush examination, sputum cytology, pleural fluid cytology, lung biopsy, and lobectomy pathology. Results The total positive rate of bronchoscopy was 64.36%, and the positive rate of central and peripheral lung cancer was 79.90% and 40.80%, respectively. Conclusions The positive rate of positive diagnosis of central lung cancer in bronchoscopy is higher, but the positive rate of positive diagnosis of peripheral lung cancer is lower.
