目的分析江苏省启东市1993—2012年间胃癌的发病率,分析其危害程度及发病特征,为胃癌的预防、研究和控制工作的实施提供依据。方法整理启东市肿瘤登记处1993年1月至2012年12月启东市户籍人群胃癌发病资料,应用年均变化百分比(APC)模型分析启东胃癌发病率的时间变化趋势。采用2000年第五次全国人口普查的标准人口年龄构成进行标化。结果 1993—2012年间启东共报告胃癌新发病例8 272例,中位发病年龄为67.92(57.50~76.00)岁。其中,男性5 269例,中位发病年龄为67.25(57.75~74.75)岁;女性3 003例,中位发病年龄为69.16(57.00~77.91)岁。胃癌年均粗发病率为40.37/10万,标化发病率25.22/10万。1993—2002年间胃癌粗发病率呈明显下降趋势(APC=-1.59,t=-4.6,P<0.01),2002—2007年胃癌粗发病率呈明显著上升趋势(APC=8.88,t=-5.3,P<0.01)。1993—2002与2002—2007年间胃癌标化发病率与粗发病率趋势相同。男女性胃癌粗发病率均随年龄增长而上升(男:APC=734.8,t=-511.2,P<0.01;女:APC=43.6,t=17.9,P<0.01),在75~80岁人群中,男女性粗发病率均达到高峰。结论 1993—2012年启东市人群胃癌发病率较高,男性和老人是高发人群。
Objective To analyze the incidence of gastric cancer between 1993 and 2012 in Qidong City, Jiangsu Province, and to analyze the degree of its harm and the incidence of gastric cancer, so as to provide a basis for the prevention, research and control of gastric cancer. Methods The incidence of gastric cancer in Qidong registered permanent residents from January 1993 to December 2012 was analyzed. The change trend of the incidence of gastric cancer in Qidong was analyzed by the average annual percentage change (APC) model. The standard population age composition of the fifth national census in 2000 was used for standardization. Results A total of 8 272 new cases of gastric cancer were reported in Qidong from 1993 to 2012, with a median onset age of 67.92 (57.50-76.00) years. Among them, there were 5 269 males with a median age of onset of 67.25 (57.75-74.75) years and 3 003 females with a median age of onset of 69.16 (57.00-77.91) years. The annual average incidence of gastric cancer was 40.37 / 100000, the standardization of incidence of 25.22 / 100000. The crude incidence of gastric cancer decreased significantly from 1993 to 2002 (APC = -1.59, t = -4.6, P <0.01). The incidence of gastric cancer increased significantly from 2002 to 2007 (APC = 8.88, t = -5.3 , P <0.01). Between 1993-2002 and 2002-2007, the incidence of gastric cancer was the same as that of crude incidence. The prevalence of gastric cancer in both men and women increased with age (male: APC = 734.8, t = -511.2, P <0.01; female: APC = 43.6, t = 17.9, P <0.01) , The crude incidence of both men and women reached their peak. Conclusion The incidence of gastric cancer was higher in Qidong City from 1993 to 2012, while the incidence of gastric cancer was higher in men and the elderly.
