中国胃癌流行病学现状

  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。  

Epidemiology of stomach cancer in China

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%CI: 26.7%-18.1%) in 2003-2005. Conclusion:Stomach cancer is a common cancer, which has heavy burden in China, particularly in rural areas. Ef-forts should be exerted for the prevention and control of the disease.
