Objective: To estimate stomach cancer incidence and mortality in Henan, 2016 and analyze the trend of stomach cancer incidence and mortality from 2010 to 2016. Methods: Stomach cancer related data in 2016 was extracted from Henan cancer registration and follow-up system. All data were qualified in validity, reliability and completeness according to the Guideline on Cancer Registration in China and International Agency for Research on Cancer (IARC/IACR). The incidence and mortality of stomach cancer were estimated by areas, gender and age based on the quality data and the registered population data of Henan province in 2016. The epidemic trend of stomach cancer was also been evaluated based on the age-standardized incidence and mortality by Chinese population (ASR China) from 2010 to 2016. Results: In 2016, the estimated incident cases of stomach cancer were 44 311. The incidence was 41.07/100 000, ASR China was 30.17/100 000, ASR by world population (ASR world) was 30.36/100 000, and the cumulative incidence rate was 3.84%. The incidences of male and female were 55.65/100 000 and 25.35/100 000, respectively. Meanwhile, 32 927 people died of stomach cancer in Henan. The mortality was 30.52/100 000, ASR China was 21.45/100 000, ASR world was 21.54/100 000, and the cumulative mortality was 2.53%. From 2010 to 2016, both the ASR China for incidence and mortality of stomach cancer in Henan showed a steady downward trend. In rural, the ASR China for incidence and mortality decreased rapidly, while the stable trend was observed in urban. Nevertheless, the incidence and mortality of stomach cancer in rural were still higher than those in urban. Conclusions: The incidence and mortality of stomach cancer in Henan province showed steadily declining trend from 2010 to 2016, and the geographical distribution difference between rural and urban areas was gradually narrowing. However, the disease burden was still high in 2016.
目的： 分析2016年河南省胃癌流行特征及2010—2016年胃癌发病与死亡变化趋势。 方法： 收集2016年河南省肿瘤登记与随访系统中胃癌的发病与死亡数据，并按照《中国肿瘤登记手册》以及国际癌症研究中心的肿瘤登记数据质量标准对数据进行有效性、完整性及可靠性评价。根据符合质量要求的数据及人口资料，按城乡、性别、年龄估计2016年河南省胃癌的流行情况。基于2010—2016年河南省胃癌中标发病率与中标死亡率数据，分析河南省2010—2016年胃癌的流行趋势。 结果： 估计2016年河南省胃癌新发病例数为44 311例，发病率为41.07/10万，中国人口标化率(中标率)为30.17/10万，世界人口标化率(世标率)为30.36/10万，累积发病率为3.84%。男性和女性的发病率分别为55.65/10万和25.35/10万。2016年河南省胃癌死亡例数约32 927例，死亡率为30.52/10万，中标率为21.45/10万，世标率为21.54/10万，累积死亡率为2.53%。2010—2016年河南省胃癌中标发病率和死亡率呈现平稳下降的趋势。农村地区胃癌的中标发病率和死亡率下降趋势明显，而城市地区整体平稳；农村地区的胃癌中标发病率和死亡率仍然高于城市地区。 结论： 虽然2010—2016年河南省胃癌发病率和死亡率整体呈下降趋势，且农村和城市地区的地区差异逐渐缩小，但是河南省胃癌流行形势依然严峻。.
