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.
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.
分析1975年至1991年在西班牙拉里奥哈地区检测出的557例膀胱癌患者的生存率。
方法/结果：采用Kaplan Meier法以及Mantel和Haenszel法进行统计分析。所分析的每个5年时间段的生存率分别为69%、58%和73%。大多数死亡发生在最初24个月内。浸润性肿瘤的生存率分别为25%、21%和0%，浅表性肿瘤的生存率分别为84%、76%和85%。男性和女性的生存率无统计学显著差异。
膀胱癌患者的生存率有所提高。浸润性膀胱肿瘤患者的预后较差。男性和女性的生存率无统计学显著差异。
