Objective:
To analyze survival in 557 cases of bladder cancer that had been detected in La Rioja (Spain) from 1975 to 1991.
Methods/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.
Conclusion:
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.
