Abstract: Objective To investigate mortality and other hazards posed by bladder carcinoma to residents of Guangxi.Methods Data were collected on bladder carcinoma in Guangxi during 2004~2005.Crude mortality rates，standardized mortality rates，potential years of life lost （PYLL），and potential years of life lost rate （PYLLR） were analyzed.Results The crude mortality rate due to bladder carcinoma was 0.97 per 100 000 for both genders，1.33 per 100 000 for males and 0.56 per 100 000 for females.The rate was 2.38-fold higher for males than for females，and this difference was significant （u=3.60，P<0.05）.The mortality rate was significantly higher during this period than during 1990~1992 （u=1.97，P<0.05）.PYLL was 285 person-years for males and 60 person-years for females；PYLL rates were 0.07% for males and 0.02% for females.Conclusions Mortality due to bladder carcinoma seems to be increasing，with mortality higher among males than among females.Thus bladder cancer appears to pose a greater risk to males than to females.
