中国肿瘤登记的代表性研究

[目的]对我国目前肿瘤登记点的代表性进行分析，为将来登记处建设规划提供依据。[方法]对上报全国肿瘤登记中心的2004年年报的死亡登记数据与全国第三次死因调查结果相比较，用负二项回归方法对相对死亡率指数进行统计学检验，验证登记点与死因监测点主要肿瘤死亡率的符合程度。[结果]肿瘤登记点合计以及城市地区死亡率和死因调查结果接近；而农村地区死亡率比死因调查结果高13％，男性和女性分别高15．7％和10．7％，差别较为显著。[结论]我国肿瘤登记处数据在全国水平有一定的代表性，但尚不能反映不同地区的实际肿瘤负担，尤其对农村地区的实际水平有所高估．主要癌肿差异显著。在下一步的肿瘤登记规划中，应加强对农村地区非肿瘤高发区的登记网络建设。

A Representative Study of Cancer Registry in China

[Purpose ] To investigate representative cancer registration data in China and provide information to luther layout for cancer registry. [Methods] The data from Cancer Registration Annual Report, 2004, China were compared with the third National Death Survey. Negative binomial regression was used to estimate site-specific cancer mortality rate ratios between the cancer registration and the third death survey. [Result] The general cancer estimated mortalities from whole cancer registries and in urban areas were close to the third death survey, but mortality was over-estimate for 13% for rural area （male, 15.7%; female 10.7%） with significan differences. [Conclusion] Although cancer registration data of whole country is representative, they could not reflect real cancer burden in rural areas, over-estimate for rural areas was existed especially in some particular cancer types. Setting up new cancer registries in non-high risk areas of rural areas should be enhanced in further net construction for cancer registration.
