广东省社区人群大肠癌流行病学调查

Epidemiology investigation of colorectal cancer on community group in Guangdong province

目的探讨广东省社区人群大肠癌流行病学特征。方法选取广东省惠东县5个镇2005年7月1日时间截面的全人口100 859人,用"高危人群大肠癌筛检方案"和"粪隐血试验筛检方案"进行大肠癌普查,并进行疾病登记和死因登记,探讨广东省一个完整社区人群大肠癌的患病和发病情况。结果广东惠东社区人群中的大肠癌总粗发病率为15.2/10万(男17.2/10万,女13.0/10万),标化发病率为17.6/10万(男19.5/10万,女16.7/10万)。粗患病率41.9/10万(男46.5/10万,女37.2/10万),标化患病率为49.0/10万(男54.1/10万,女45.6/10万)。粗死亡率为5.0/10万(男5.9/10万,女4.0/10万),标化死亡率为6.4/10万(男7.2/10万,女5.7/10万)。结论广东省惠东社区大肠癌发病率(17.6/10万)低于我国高发区,但接近全国总体水平及世界平均水平。

Objective To explore the epidemiology characteristics of colorectal cancer on community group in Guangdong province. Methods Huidong was took as the research spot to investigate the sickness and incidence of colorectal cancer among a whole community group in Guangdong province, and two projects were used simultaneously： ＂screening of colorectal cancer in high risk group＂ and ＂screening project using fecal occult blood test＂. The numeration time for population of 10 towns was set at July 1, 2005. Five towns were sampled out from Huidong with 100 859 persons. Meanwhile, the diseases and death cause registering system was established. Results The incidence of colorectal cancer in Huidong community group was 15.2/100 000 （male 17.2/100 000, famale 13.0/100 000）, the age-adjusted incidence was 17.6/100 000 （ male 19. 5/100 000, female 16. 7/100 000 ）. The morbility was 41.9/100 000 （ male 46.5/100 000, female 37.2/100 000）, the age-adjusted morbility was 49. 0/100 000 （male 54. 1/ 100 000,female 45.6/100 000 ）. The mortality was 5.0/100 000 （male 5.9/100 000, female 4. 0/ 100 000） and the age-adjusted morbility was 6.4/100 000 （male 7. 2/100 000, female 5.7/100 000）. Conclusion The incidence of colorectal cancer in Huidong community group is lower than that of high incidence area in China, but gets close to the normal incidence area of China and general level of the world.
