目的 :了解启东市食管癌发病流行规律 ,为食管癌防治措施提供依据。方法 :利用启东市 1972～ 2 0 0 0年食管癌发病数据库及历年人口资料 ,计算粗发病率、标化发病率、截缩发病率并分析性别及年龄分布 ,应用 χ2 、分 3时段作时间趋势分析。结果 :2 9年间 ,食管癌粗发病率男性差异无显著性 (P >0 .0 5 ) ,女性有上升趋势 (P <0 .0 1) ;男∶女为 2 .16∶1;标化发病率男高于女 ,但均呈现下降趋势 (P <0 .0 1) ,以男性下降速度为快。食管癌发病年龄主要集中于中老年人 ,中位发病年龄男性较女性提早 3年。三个时期相比较 ,1991～ 2 0 0 0年标化发病率及截缩发病率下降速度均快于 1981～ 1990年与 1972～ 1980年。结论 :食管癌总体水平呈下降趋势。
Objective: To understand the prevalence of esophageal cancer in Qidong and to provide evidence for the prevention and treatment of esophageal cancer. Methods: According to the database of incidence of esophageal cancer from 1972 to 2000 and the data of population over the years, the incidences of crude disease, standardized incidence and truncation were calculated and sex and age distribution were analyzed. The χ2, trend analysis. Results: The crude incidence rate of esophageal cancer was not significantly different between males and females (P <0.01); the male and female was 2.16:1 The incidence was higher in males than in females, but both showed a downward trend (P <0.01), with males declining rapidly. The age of onset of esophageal cancer mainly in the elderly, the median age of onset men than women 3 years earlier. Compared with the three periods, the decreasing rates of the standardized incidence and the incidence of truncation from 1991 to 2000 were all faster than those from 1981 to 1990 and from 1972 to 1980. Conclusion: The overall level of esophageal cancer is declining.
