title: [Bladder cancer survival, study of 557 cases identified at the autonomous community of La Rioja from 1975 to 1991].
abstract: OBJECTIVE
  To analyze survival in 557 cases of bladder cancer that had been detected in La Rioja (Spain) from 1975 to 1991.
  
  
  RESULTS
  The Kaplan Meier and Mantel and Haenszel methods were used for the statistical analyses. The survival rate for each 5-year period analyzed was 69%, 58% and 73%, respectively. Most deaths occurred within the first 24 months. The survival rates were 25%, 21% and 0%, respectively, for infiltrating tumors and 84%, 76% and 85% for superficial tumors was of the. The survival rates for males and females were not statistically significant.
  
  
  CONCLUSIONS
  The survival rate in patients with bladder cancer has increased. Patients with infiltrating bladder tumors have a worse prognosis. The survival rates for males and females are not statistically significantly different.
