胸部CT、纤维支气管镜及痰脱落细胞联合检查在中央型肺癌诊断中的价值

The diagnostic value of CT,fibro-bronchoscopy and sputum cytology for central pulmonary carcinoma

目的:评价胸部CT、纤维支气管镜及痰脱落细胞联合检查对中央型肺癌的诊断价值。方法:回顾分析130例经病理证实的中央型肺癌,全部病例均有胸部CT、支气管镜检查及痰脱落细胞检查,其中40例分别于纤支镜检查前后送检痰脱落细胞,对各种检查结果进行对照分析。结果:痰脱落细胞学检查、胸部CT、纤维支气管镜对中央型肺癌的诊断符合率分别为34.6%、83.7%、89.2%,纤支镜术后痰脱落细胞学检查的诊断符合率可达到43.1%。胸部CT与纤维支气管镜、痰脱落细胞学检查结合诊断符合率达100%。组织学类型以鳞癌、小细胞未分化癌多见,分别为62.4%、35.9%。结论:胸部CT、纤维支气管镜及痰脱落细胞联合检查可提高诊断阳性率。

Objective：To evaluate the diagnostic value of central pulmonary carcinoma with chest CT,fibro-bronchoscopy and sputum cytology. Methods： 130 cases of central pulmonary carcinoma confirmed by pathology were reviewed and analyzed. All cases had chest CT fibro-bronchoscopy and sputum cytology, The results of each examination were analysed comparatively. Results：The diagnostic rate of central pulmonary carcinoma by sputum cytology ,CT and fibro-bronchoscopy was 34. 6% , 83.7% and 89. 2% respectively. The diagnostic rate of central pulmonary carcinoma by sputum cytology after fibro-bronchoscopy was 43.1%. The diagnostic rate of central pulmonary carcinoma by sputum cytology combined with CT and fibro-bronchoscopy was up to 100%. In histology squamous cell and small cell undifferentiated carcinoma were more common, in 62.4% and 35.9% respectively. Conclusion：CT combined with fibro-bronchoscopy and sputum cytology is benefit to the diagnosis of central pulmonary carcinoma.
