921例经支气管镜确诊肺癌的临床特点分析

目的 对921例经支气管镜确诊肺癌的临床特点进行分析。方法 采用常规支气管镜检查，镜下直视、盲目活检组织病理检查和刷检细胞学检查的方法，确定诊断和病理类型。结果 肺癌的发病率在40岁以下显著增加，50-69岁为发病高峰，70岁以下开始下降。921例肺癌中，鳞癌占38．5％，腺癌和低分化癌分别占27．4％和21．9％，小细胞癌占8．7％，其他占3．5％。男性鳞癌的发病率最高，女性腺癌发病率最高。结论 50-69岁是肺癌的高发年龄段，发病率最高的是鳞癌，其次是腺癌、低分化癌和小细胞癌。男女性别的病理类型分布有差别。重视支气管镜检查和提高活检技术，可显著提高诊断率。为临床治疗提供依据。

Clinical characterization analysis of 921 cases lung cancer diagnosed by bronchoscope

Objective] To analyse the clinical characteristics of 921 cases lung cancer diagnosed by bronchoscope. Methods] Normal bronchoscope examination was used to confirm the mass localization by direct view and the diagnosis of pathological types by blindness biopsy, and cytological examination by brush test. Results] The incidence of lung cancer were significantly increased in patients of age over 40 years old. The peak level of incidence at the age from 50 to 69, and then decreased at age over 70. In the 921 cases, the proportion of squamous cell carcinoma was 38.5%, adenocarcinoma and poor differentiation carcinoma were 27.4% and 21.9% respectively. Small cell lung cancer was 8.7% and others were 3.5%. The predominant pathological type of lung cancer in this investigation was squamous cell carcinoma in male, and adenocaroinoma in female. Conclusion] The higher incidence of lung cancer at age from 50 to 69, and the predominant types of pathology was squamous cell carcinoma, adenocarcinoma, poor differentiation carcinoma and small cell lung cancer in turn. Some difference of distribution in pathological type existed in sex. The bronchoscope examination and improvement the biopsy technique should be emphasized, which may be the effective clinical approach for diagnosis of lung cancer, and further provide a reliable evidence for its clinical therapy.
