[Estimates and prediction on incidence, mortality and prevalence of brain and neurologic tumors in China, 2008].

OBJECTIVE:To estimate the incidence, mortality and 5-year prevalence of brain and neurologic tumors in China, 2008. METHODS:Data from 36 cancer registries in China and from the Third National Death Survey in China were used to estimate the incidence, mortality and 5-year prevalence of brain and neurologic tumors in 2008, using the mathematical models. Prediction on the incidence, and mortality of brain and neurologic tumors in the next 20 years was also carried out. RESULTS:In 2008, the incidence of brain and neurologic tumors in China was 66 454 (2.4%) and the incidence rate of age-standardized was 4.4/100 000, ranking tenth among all the cancers. The mortality of brain and neurologic tumors in China was 45 573 (2.3%), with mortality rate as 3.0/100 000, which ranked seventh among all the cancers. The 5-year prevalence of brain and neurologic tumors in China was 91 449 (2.0%) and the proportion was 8.6/100 000, which ranked twelfth among all the cancers. Incidence rates of brain and neurologic tumors in all the age groups were similar in both sexes, but the rate of incidence increased faster before 40 years old and slowed down thereafter. In the next 20 years, data from the prediction showed that the incidence and mortality of brain and neurologic tumors in China would gradually increase. CONCLUSION:The burden of brain and neurologic tumors was increasing continuously.
