    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 tumor 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.
