Abstract:
Objective To investigate the incidence and mortality of brain tumor in Zhejiang cancer registration areas from 2000 to 2009.Methods Data from 6 Cancer registration areas of Zhejiang province were collected.Number of cases,crude rates,proportions,age standardized rates,cumulate rates,cut rates,age-specific rates and annual percentage change (APC,95％ CI) of brain tumor incidence and mortality were analyzed.Results There were 5 123 new diagnosed brain tumor cases in Zhejiang cancer registration areas,accounting for 3.14％ of all the new cancer cases.The incidence rate of brain tumor was 8.53/100 000,and the standardized incidence rate by Chinese population was 5.72/100 000,ranking the 7th in cancer incidence spectrum of anatomic sites.Agespecific incidence of brain tumor increased along with age,and peaked among 70-74 age groups (24.09/100 000).The annual incidence rate of brain tumor increased from 2000 (6.87/100 000) to 2009 (8.35/ 100 000),with APC as 1.58％ (95 ％ CI:-2.17％-5.47％,no statistical significance).A total of 2 357 deaths caused by brain tunor were reported from 2000-2009,accounting for 2.47％ of all the cancer death cases.Mortality rate on brain tumor appeared to be 3.92/100 000,with the standardized mortality rate by Chinese population as 2.45/100 000,ranking the 7th in cancer mortality spectrum of anatomic sites.The age-specific mortality of brain tumor remained low among 0-39 year-olds,and reached the peak at 80-84 age groups (17.64/100 000).The annual mortality rate of brain tumor decreased from 2000 (4.30/100 000) to 2009 (3.83/100 000) with minor fluctuation,and the APC was-0.65％ (95％CI:-3.35％-2.12％,no statistical significance).Conclusion Brain tumors incidence and mortality in Zhejiang cancer registration areas were at a relatively high level.People who were at middle-age,especially above 70 years old should be the key targets for protection on this disease.Brain tumor incidence rates increased annually in Zhejiang,which should be called for attention.
