1981-2002年天津市食管癌流行趋势

目的 分析1981-2002年天津市食管癌流行趋势变化,帮助预测未来流行趋势,为进一步加强食管癌防治工作提供科学依据.方法 统计1981-2002年天津市内六个区食管癌的发病及死亡资料,计算男女各年龄段发病率、粗发病率、粗死亡率及世界人口标化发病率、标化死亡率等指标,分析天津市22年食管癌的流行趋势.采用年均变化百分比描述发病率和死亡率的升降幅度.结果 1981-2002年天津市累计报告食管癌病例8206例,其中男性5533例,女性2673例,男女比例为2.07∶1.45岁之前食管癌发病率较低(＜1/10万),45岁后逐渐上升,中位发病年龄69岁(四分位数间距为62～75岁).女性发病高峰年龄为75～80岁,较男性(80～85岁)提前,近几年女性发病高峰年龄出现后移,渐与男性接近.1981-2002年,食管癌粗发病率和标化发病率均呈下降趋势.男、女粗发病率和标化发病率年均分别下降2.22%、3.56%和5.18%、6.56%.各年龄组的发病率均呈下降趋势.22年间天津市食管癌死亡率呈下降趋势.结论 天津市食管癌发病率呈下降趋势,但食管癌患者的生存情况未获明显改善.

Trends in incidence and mortality of esophageal cancer from 1981 to 2002 in Tianjin

Objective To investigate the trends in incidence and mortality of esophageal cancer from 1981 to 2002 in Tianjin,China and to predict future trends and facilitate future prevention.Methods All new cancer cases registered in the Tianjin Cancer Registry between 1981 and 2002 were reviewed.Yearly age-specific,crude and age-adjusted incidence rates were calculated for males and females.Secular trends of incidence and mortality were indicated by the estimated annual percentage change(EAPC).Results A total of 8206 cases of esophageal cancer were reported in Tianjin form 1981 to 2002,with 5533 males and before 45 years,but increased rapidly after 45 years.The median age of esophageal cancer cases was 69 years,with quartile range from 62 to 75 years.The peak for age specific incidence in females was 75-80 years,which was earlier than that in males(aged 80-85).But recent data indicated that the peak age in females had increased and became similar to that of the males.The crude and age-standardized incidence rates(ASIR)of esophageal cancer decreased in last 22 years.For male and female,crude incidence decreased by 2.22% and 3.56% per year and ASIR decreased by 5.18% and 6.56% per year.The mortality of esophageal cancer decreased in the last 22 years.Conclusion The incidence of esophageal cancer decreased in the last 22 years in Tianjin,but there is little overall improvement in survival.
