摘    要: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。

Abstract:Objective:To study the epidemic trend of the incidence rate of esophagus cancer in Qidong in order to take measures for prevention and treatment in the field.Methods:Data base of cancer registration was used to calculate the crude incidence rates, age-standardized incidence rates and truncated incidence rates regarding to age and sex, and chi-square test was used to analyze the time trend by period. Population data was collected from household registration of local security bureau. Results:There is no significant changes for crude incidence rate of esophageal cancer for males in 29 years(P>0 05), while the rate for females was in increase (P<0.01). The sex ratio is 2.16∶1. The age-standardized rates showed decreasing trends (P<0.01) for both males and females, but the former was faster than that of the latter. The incidence cases were often seen after age of forties, accounting for a large percentage. The median incidence age of males is three years earlier than that of females. The down speed of the standardized rate and the truncated incidence rate in 1991-2000 was the highest among rates from three periods of 1972-1980, 1981-1990, and 1991-2000. Conclusions:The total incidence of esophagus cancer in Qidong was a dereasing trend.
Keywords:Esophagus neoplasm    Incidence rate    Trend analysis
