Abstract
BACKGROUND: In recent years, more and more young patients have been suffering from lung cancer, and these young patients do not always have good prognosis. This article wants to study the relationship between the histopathology with gender, location and the sign of fibrobronchoscopy in lung cancer patients under the age of 40. METHODS: The article analyzed retrospectively the fibrobronchoscopy data of 469 young lung cancer patients under the age of 40. RESULTS: In the 469 patients, the male/female ratio was 2.42/1. The most common histopathology was squamous cell carcinoma (33.0%), followed by adenocarcinoma (26.%) and small cell carcinoma (20.5%). The ratio of squamous cell carcinoma in male (40.7%) was more than in female (14.6%), and ratio of adenocarcinoma in female (43.1%) was more than in male (19.0%), it is obviously different on the distribution of cancer histopathology between male and female patients (P >0.05). The location of lung carcinoma was more likely in the bilateral upper lobars and in the right lung, 81.4% had direct signs. CONCLUSIONS: Lung cancer patients under the age of 40, squamous cell carcinoma is significantly more in male group, but adenocarcinoma is significantly more in female group. This study suggests fibrobrochoscopy is an indispensable approach in the diagnosis of young lung cancer. Paying more attention to the lung cancer of young patients and examining with fibrobronchoscopy will be found much helpful to early diagnosis.
