title: [Are there any differences between the characteristics and the behavior of bladder cancer according to the age of presentation? Our experience].
abstract: BACKGROUND
  Owing to the different results from the series that evaluate the behavior of the bladder cancer according to the age at the moment of the diagnosis, our objective is based on valuing the characteristics and behaviour according to age of appearance.
  
  
  METHODS
  A retrospective study of bladder cancer diagnosed in our area during decade 1993-2003, distributed in 3 intervals of age and some characteristics and behaviour are valued.
  
  
  RESULTS
  Elderly patients present greater tumors, non differentiated and with greater rate of progression to infiltrated. Moreover the age, the pathological stage and the tumorlike degree appear as independent significant factors in the multivariant study.
  
  
  CONCLUSIONS
  In our experience, the patients greater than 70 years present neoplasms of similar clinical characteristics, although pathologically more aggressive, with greater percentage of progression and worse survival.
