The diagnosis value of chest CT,bronchoscopy and sputum cytology for central lung cancer

Objective To investigate the diagnosis value of chest CT,bronchoscopy and sputum cytology for central lung cancer.Methods A retrospective analysis of clinical data of 120 cases in our hospital with central lung cancer confirmed by pathology.All patients were received chest CT,bronchoscopy and sputum cytology.The diagnostic rate of three methods were compared to evaluate the diagnosis value for central lung cancer.Results The diagnostic rate of central lung cancer by chest CT,bronchoscopy and sputum cytology were 87.5%,91.7% and 40.8%.the diagnosis coincidednce rate of fiber bronchoscope was highest,the chest CT,exfoliative cell examination of sputum was lowest,differences were statistically signifincant(P0.05).The diagnostic rate of three methods combined was 100.0%.In the organization histological type,squamous cell carcinoma and poorly differentiated carcinoma were more common,of 62.5% and 15.8% respectively.Conclusion In the diagnosis value of central lung cancer,fiberoptic bronchoscopy has the maximum value.Its diagnosis rate was the highest.Chest CT and sputum cytology could be used as the good complementary approaches.The three methods combined can significantly improve the diagnosis rate.
