Lung cancer in young patients aged from 15 to 44 years: incidence trend, current status and survival analysis from 2002 to 2005.

Abstract

Objective:To analyze the incidence trend,current status and survival period of young patients with lung cancer aged from 15 to 44 years in Shanghai between 2002 to 2005.Methods:All the data were collected from the database of registration and ma-nagement system of diagnosed cancer cases in Shanghai city organized by Shanghai Municipal Center for Disease Control Prevention.The incidence trend was analyzed by using APC(annual percent change)model.The survival period and median survival time were calculated by using SPSS 12.0 software and life table method.The univariate and multivariate analyses were analyzed by using Kaplan-Meier and COX regression model,respectively.Results:A total of 972 young patients with lung cancer who aged from 15 to 44 years were diagnosed in Shanghai between 2002 and 2005,accounting for 3.09% of the whole lung cancer population.The ratio of male and female patients was 1.63∶1.The percentage of adenocarcinoma in young patients was higher than that in whole lung cancer population at the same period,while the TNM stage was not significantly different between male and female young patients.Multivariate analysis demonstrated that gender,pathological classification and TNM stage were independent prognostic factors for young patients with lung cancer.Conclusion:The lung cancer had different characteristics in young patients compared with that in whole lung cancer population in Shanghai city.It was necessary to further investigate the biologic behavior of lung cancer in young patients.
