UNASSIGNED: Conclusions This study demonstrated a high incidence of competing mortality in @entity1 with @entity135 ( @entity135 ). It identified age to be an independent prognostic factor for @entity5 mortality. These findings contribute to the appropriate treatment selection in clinical settings and study design in clinical trials. Objectives To investigate the incidences of second @entity5 (SPC) and @entity5 mortalities among @entity1 with @entity135 and reveal the determinant factors for these mortalities. Methods This study reviewed the records of 334 @entity1 with @entity135 between 2006-2012. The cumulative incidences of @entity135 , @entity5 , and SPC mortalities were estimated. A Fine and Gray regression model was used to investigate factors associated with @entity5 and @entity5 mortalities. Results The 5-year cumulative incidences of @entity135 , SPC, and @entity5 mortalities were 28.0%, 2.5%, and 6.5%, respectively. In univariate analysis, the factors associated with SPC mortality were @entity5 site and comorbidity, whereas those associated with @entity5 mortality were age, gender, and comorbidity. In multivariate analysis, age (sub-distribution hazard ratio   =   2.59) was the independent risk factor for @entity5 mortality.
