2014-2015年上海金山区社区居民大肠癌筛查结果分析

目的 通过对上海市金山区社区居民进行大肠癌筛查，探讨社区居民大肠癌筛查的效果，为探索大肠癌筛查策略提供参考。方法 对上海市金山区常住居民进行大肠癌筛查。采用问卷调查结合粪便隐血试验（fecal occult blood test，FOBT）的两步筛查模式，初筛阳性者行全结肠镜检查，并对结果进行分析。结果 完成初筛58 215人，初筛完成率99.07%，初筛阳性率25.44%，肠镜依从性41.87%，大肠癌检出率0.45%，腺瘤检出率46.40%，总病变检出率35.74%，男女间检出率差异有统计学意义（χ2=224.337，P<0.001），随着年龄的增大，检出率不断上升，各年龄组间检出率差异有统计学意义（χ2=37.788，P<0.001）。结论 大肠癌筛查能有效地检出居民大肠癌及腺瘤等病变，对于大肠癌的早发现、早诊断、早治疗有重要意义。

There were significant differences in detection rates between men and women(χ2=224.337,P<0.001). With the increase of age, the detection rate was rising. The detection rate of all age groups were significant different(χ2=37.788,P<0.001). Conclusions Colorectal cancer screening can detect colorectal cancer, adenoma and other diseases. It has important significance for early detection, early diagnosis and early treatment of colorectal cancer.
