中国胃癌流行病学现状

Epidemiology of stomach cancer in China

目的:通过对中国人群肿瘤登记数据中胃癌资料进行分析,了解全国胃癌流行现状。方法:根据全国肿瘤登记中心的数据,评估全国胃癌流行情况及胃癌长期变化趋势。结果:2012年中国胃癌新发病例约42.4万例,死亡病例约29.8万例。2000年至2012年我国城市地区男性与女性胃癌发病率、死亡率保持平稳,农村地区男性呈上升趋势,农村地区女性变化不大,调整年龄后发病率和死亡率均呈下降趋势。2003年至2005年胃癌5年相对生存率为27.4%(95%CI:26.7%~28.1%)。结论:胃癌是中国常见的恶性肿瘤,疾病负担严重,农村地区尤为明显,是国家癌症防治的重点。

Objective： Population-based cancer registration data were used to analyze stomach cancer epidemiology in China. Meth- ods： Stomach cancer data were retrieved from the National Central Cancer Registry Database, and incident and death cases were esti- mated. The trend of stomach cancer was analyzed. Results： Approximately 424,000 new cancer cases and 298,000 cancer deaths oc- curred in China in 2012. The incidence and mortality rates of stomach cancer in urban males and females remained stable in 2000- 2012, whereas the rates in rural males increased and less changes were observed in rural females. After age standardization, both inci- dence and mortality rates significantly decreased. The five-year age-standardized relative survival rate was 27.4% （95%C1： 26.7%- 18.1%） in 2003-2005. Conclusion： Stomach cancer is a common cancer, which has heavy burden in China, particularly in rural areas. El- forts should be exerted for the prevention and control of the disease.
