ABSTRACT

Objective To investigate the bladder cancer incidence and mortality in cancer registries of Zhejiang province during 2000 to 2009.Methods The data were collected from six cancer registries in Zhejiang province.Staff of Zhejiang Provincial Cancer Prevention and Control Office checked the data and calculated crude rate,standardized rate and trend. Results The incidence rate of bladder cancer in Zhejiang cancer registration areas was 6.97 /105 during 2000 to 2009. The incidence of male was higher than female,the ratio was 3.40∶1.The incidence rate increased from 2000(6.36 /105 ) to 2009(7.99 /105 ),with the Annual Percent Change (APC)of 3.69% (95% Confidence Interval2.49% ~4.90%). The mortality rate of bladder cancer in Zhejiang cancer registration areas was 2.00 /105 during 2000 to 2009.The mortality of male was higher than female,with the ratio 3.27∶1.The mortality of bladder cancer showed ascending trend with a slight fluctuation from 2000 to 2009 (APC =2.28%).The incidence and mortality of bladder cancer showed significantly increasing in above 55 years old age groups.The incidence rate peaked in the 80 -84 age group,while the mortality peaked at age group of over 85 years old.Conclusion The bladder cancer prevention and control work should be focused on the elderly male population in Zhejiang province.
