OBJECTIVE
In many countries, the cervical cancer prevalence has declined but less information about the changes is available in China. This study aims to understand the epidemiological characteristics and trend of cervical cancer in China.
METHODS
Cervical cancer data of 11 cancer registries during 1988-2002 in China were analyzed. The age and urban/rural differences and trend of cervical cancer incidence and mortality were described and discussed.
RESULTS
During 1988-2002, a total of 6007 incidence cases and 3749 mortality cases of cervical cancer were reported in the 11 cancer registries. The incidence crude rate of cervical cancer was 3.80/100,000 and the world age adjusted rate was 2.78/100,000. In the same period, the mortality crude rate was 2.37/100,000 and the world age adjusted rate was 1.66/100,000. Declined incidence and mortality trends were observed during this period in urban as well as in rural areas. When calculating the rates by age group, we found that the declining trends were only for older women and increasing trends for younger women, especially for women in the rural areas.
CONCLUSION
The incidence and mortality rates declined during the period of 1988-2002 in China for older women. The younger women showed an increasing trend during the same period, especially for women in rural area.
目的
在许多国家，宫颈癌的患病率已经下降，但中国关于这种变化的信息较少。本研究旨在了解中国宫颈癌的流行病学特征和趋势。
方法
分析了中国 1988-2002 年 11 个癌症登记处的宫颈癌数据。描述和讨论了宫颈癌发病率和死亡率的年龄和城乡差异及趋势。
结果
在 1988-2002 年期间，11 个癌症登记处共报告了 6007 例宫颈癌发病病例和 3749 例宫颈癌死亡病例。宫颈癌发病率粗率为 3.80/100000，世界年龄调整率为 2.78/100000。同期，宫颈癌死亡率粗率为 2.37/100000，世界年龄调整率为 1.66/100000。在此期间，城市和农村地区的发病率和死亡率均呈下降趋势。按年龄组计算发病率时，我们发现下降趋势仅见于年龄较大的女性，而年轻女性的趋势则上升，尤其是农村地区的女性。
结论
1988-2002 年间，中国年龄较大的女性宫颈癌发病率和死亡率呈下降趋势。同期年轻女性呈上升趋势，尤其是农村地区的女性。
