Diadynamic Value of Fiberbrornchoscope on 111 Cases of Youth Lung Cancer

Objective To study the clinical characteristics and the features of fibrobronchoscopy in lung cancer patients under 39 years of age.Methods We analysed retrospectively the fibrobronchoscopic data of 111 young lung cancer patients.Results The proportion of young patients with lung cancer in all lung cancer patients was 6.55%.The male/female ratio was 1.47/1.The lung tumor,slabby vague and pulmonary atelectasis were detected in the 95.5% patients,right lung cancer is more than left lung.The hilus of lung and upper lobes were the most common regions;The most frequent histologic types was small cell carcinoma(36.94%),followed by squamous cell carcinoma(20.72%) and adenocarcinoma(12.61%),and carcinoma in situ.Among 111 young lung cancer patients,80.18% had direct sign,18.02% had indirect sign.Conclusions Lung cancer in young patients is prone to be misdiagnosed as pneumonia or tuberculosis.Therefore,it is necessary to pay more attention to the lung cancer of young patients.
