Comparisons of multiple characteristics between young and old lung cancer patients.
2012
Abstract Risk factors that contribute to younger patients with lung cancer are still relatively unknown. The aim of this study was to compare the clinical characteristics, histological types, stages at diagnosis, treatment modalities and survival rates between young and old patients with lung cancer. The study was designed as a retrospective review of all lung cancer patients admitted to the Third Affiliated Hospital of Harbin Medical University from 1998 to 2008. Survival analyses using univariate and multivariate approaches were performed to compare the survival rates between different age groups and to discover potential prognostic factors. This research included 3320 patients with primary lung cancer, of whom 626 (18.8%) were 45 years old or younger at the time of diagnosis. The percentage of smokers and the male to female ratios between the young and old patient groups were 51.27% vs. 70.6% (P
