摘　　要：目的通过对16年来胃癌发病情况的动态观察,分析其流行病学变化趋势及可能成因。方法将我院1986年～2001年胃镜检查资料列为研究对象,人为分成1986～1993和1994～2001前后两组,探讨检出率和性别的差异,并以1989年和1999年为例,比较10年间胃癌平均发病年龄的变化。结果16年来随着胃镜受检人数的增加,胃癌检出人数亦呈波动上升趋势,但是胃癌检出率却呈波动下降趋势.前后两组检出率分别为11.29%(1102/9760)和7.28%(2325/31945),差异显著(P<0.001,χ2=132.79)。后组男女性别比(2.9)低于前组(3.5)(P<0.05,χ2=5.23)。1999年平均发病年龄为1989年的1.08倍(P<0.001,μ=6.60)。结论盐城地区胃癌检出率呈波动下降趋势,胃癌患者平均发病年龄上升,男性比例有所下降,可能与环境因素改变有关。Objective To analyze gastric cancer epidemiology during the last sixteen years. Methods Data of endoscopy examination between 1986 and 2001 was divided into two groups and their differences in detection rate and sex ratio were investigated. The change of mean age was compared between 1989 and 1999. Results The number of gastric cancer patients went up fluctuatedly during the past sixteen years attended by arising endoscopy examination patients, but detection rate declined fluctuatedly. The former detection rate （ 11.29 % ） was higher than that of the latter （7.28 % ） significantly （ P 〈 0.001, X^2 = - 132.79） .The sex ratio of the latter （2.9） was lower than that of the former （3.5） （ P 〈 0.05, X^2 = 5.23）. The mean age of 1999 was 1.08 times of 1989 （ P 〈 0.001, = 6.60）. Conclusion The detection rate of gastric cancer in Yancheng district declines fluctuatedly. The mean age of gastric cancer goes up , and the proportion of male patient goes down. All these changes may be due to environment.
