Clinic charactoristie analysis of young lung cancer patiens under 40 years old

Objective To study clinic caharacteristics in young lung cancer patients.Methods We analysed restrospetively the data of 102 young lung cancer patients enrolled between 1994 and 2005.Results Among them,the number of male patinents was 70 and female 32,male to female ratios was 2.2 vs 1.The average time of final diagnosis was 3.8 months and the misdiagnosis rate was 71.6%.The most frequent histologic type was adenocarcinoma(55/102),followed by squamous cell arcinoma (14/102),small cell carcinoma(13/102)and unstereotypia(20/102).According to typing standard,102 cases included 4 of Ⅰ stage,7 of Ⅱ stage,16 of ⅢA stage,47 of ⅢB stage and 28 of Ⅳstage. Conclusions Lung carcinomas of the young patients growed quickly and disseminated early which were untypical in clinic appearance.In young lung cancer which pathologic type was principally adenocarcinoma,the female proportion stepped up and the correlation attenuated between young lung cancer and smoking.
