目的：探讨纤支镜检查在肺癌诊断中的作用及肺癌病理学分型。方法：回顾分析４０４例纤支镜检查确诊为肺癌患者的临床资料及检查结果。结果：肺癌的高危人群为中老年男性，发病部位右肺多于左肺，上叶多于下叶；因肺癌病理组织学分类不同，其在纤支镜下表现各异。结论：纤支镜检查是确诊肺癌的重要手段，其镜下表现和病理分类可给肺癌临床治疗提供参考
Objective: To explore the role of fiberbronchoscopy in the diagnosis of lung cancer and the pathological classification of lung cancer. Methods: The clinical data and examination results of 404 patients diagnosed with lung cancer by fibrobronchoscopy were retrospectively analyzed. Results: The high-risk groups of lung cancer were middle-aged and old men. The incidence of right lung was more than that of the left lung and the upper lobe was more than the lower lobe. Because of the different pathological histology of lung cancer, its performance was different under bronchoscopy. Conclusion: Fibrobronchoscopy is an important method for the diagnosis of lung cancer. Its microscopic appearance and pathological classification can provide reference for clinical treatment of lung cancer.
