2003-2007年中国胃癌发病与死亡情况分析

目的:分析2003-2007年中国胃癌的发病与死亡情况.方法:利用2003-2007年全国32个市/县肿瘤登记数据中胃癌的统计结果,分析中国近期胃癌发病率和死亡率的水平及变化趋势.结果:2003-2007年中国胃癌发病率为33.14/10万,世界人口标化率为23.09/10万,居恶性肿瘤第2位,男性高于女性.同期胃癌死亡率为24.34/10万,世界人口标化率为16.39/10万,居恶性肿瘤死因第3位,男性高于女性.胃癌发病率和死亡率基本随年龄增长而上升；地区间男性胃癌世界人口标化发病率和世界人口标化死亡率最大差异分别为16.3倍和19.1倍,女性为17.5倍和27.0倍.结论:2003-2007年中国胃癌发病率和死亡率仍处于较高水平,不同年龄和地区间的胃癌发病和死亡水平差异较大.

Analysis of incidence and mortality of stomach cancer in China from 2003 to 2007

Objective:To analyze the incidence and mortality of stomach cancer in China from 2003 to 2007.Methods:The registration data during 2003 to 2007 from 32 cities/counties were used to estimate stomach cancer incidence and mortality and their changing trends in China.Results:The crude incidence rate of stomach cancer was 33.14/100 000 and the age-standardized rate(ASR) by world population was 23.09/100 000,ranked the second of all new cancer cases during 2003 to 2007 in China.A higher incidence rate was found in the males than in the females.In the same time period,the crude mortality rate of stomach cancer was 24.34/100 000,and the ASR by world population was 16.39/100 000,ranked the third of all cancer deaths,with a higher rate in the males than in the females.The age-specific incidence and mortality rates were increased with increasing age.The differences of ASR in the incidence and the mortality by world population among different regions were found as high as 16.3 and 19.1 folds in the males,and 17.5 and 27.0 folds in the females,respectively.Conclusion:The incidence and mortality of stomach cancer are still high in China from 2003 to 2007.There are substantial variations in the incidence and mortality rates of stomach cancer by age and region.
