Abstract:
Objective :To analyze the cancer survival rate during 1988-1991 and 1992-1995 and evaluate the prognosis of urological cancer in urban Shanghai.
Methods :Population-based cancer registration data was used in the analysis. Life table and Hakulinen's methods were used to estimate the observed and relative survival rates.
Results :During 1988-1995, the 5-year relative survival rates of male bladder, renal and prostate cancers were 57.4%, 49.9%, 36.5%, respectively, and the rate for female bladder and renal cancers were 47.6% and 53.5%, respectively. For male bladder cancer, the survival rate was higher than that of female patients. During 1988-1991 to 1992-1995, the 5-year relative survival rates of male bladder, renal and prostate cancers increased from 53.7%,41.6%,38.0% to 57.2%,50.6%,39.1 %,respectively. For female bladder cancer, the rate increased from 41.8% to 44.7 %;however in renal cancer, the rate decreased from 48.0% to 47.3%.
Conclusions :Increasing trend has been observed for the survival rate of urological cancer patients from 1988-1991 to 1992 1995 in the urban of Shanghai, but there are only statistically significant changes in male renal and prostate cancers.
