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

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.
