Characteristics and analysis of clinical features of lung cancer diagnosed by bronchoscopy in 384 male patients

Objective To study the characteristics of the bronchoscopy signs and the clinical features in male lung cancer patients.MethodsThe bronchoscopy data of 384 male lung cancer patients were analyzed retrospectively.ResultsThe most common histopathology was squamous cell carcinoma(53.13%),followed by small cell carcinoma(30.73%),and adenocarcinoma(14.32%)and the others(1.83%).More cases of squamous cell carcinoma were examined in the old-aged group compared with the middle-aged group(χ2=4.0352,P0.05),but fewer cases of small cell carcinoma(χ2=7.7671,P0.01).The diseases were mainly located in the right lung and upper lobes.92.19% patients had direct signs.70.59% squamous cell carcino-ma had proliferative changes and 52.73% adenocarcinoma had infiltrative changes.There were more proliferative changes than infiltrative changes in small cell carcinoma.ConclusionsClinical features and bronchoscopy characteristics of male lung cancer patients have particularity,and knowing these points would be helpful to clinic.
