北京社区结直肠癌筛查的初步结果分析

目的探索城市居民中老年人群结直肠癌的发病情况,并通过积极干预降低社区结直肠癌的发病率。方法北京丰台区东高地居民区16个单位50～80岁共10740人接受大肠癌筛查,9843人(91.65%)接受连续3次的便隐血(免疫法)检查,阳性患者2709人(占受检者的27.52%),其中260人(占便隐血阳性者的9.60%)接受了电子肠镜检查。结果260例接受电子肠镜检查的患者中,检出大肠癌12例,男性8例,女姓4例,年龄66～77岁。其中息肉癌变2例,直肠类癌2例(均为早期),DukeⅡ期大肠癌4例,DukⅢA期大肠癌1例。检出结肠腺瘤127例。结直肠癌的检出率为121.9/105。结论城市居民中老年人群结直肠癌的发病率呈直线上升。通过便隐血检查后,阳性患者接受肠镜检查可以发现早期结直肠癌。建议此项工作应在城市居民中广泛开展以改善结直肠癌的预后。

The preliminary result of colorectal cancer (CRC) screening in Beijing community

Objective To investigate the incidence of colorectal cancer(CRC) in middle aged and old aged in urban population. Try to reduce the incidence of CRC of community by positive intervention. Methods A total of 10740 persons from the population of 16 units in Beijing DongGaoDi, aged 50~80 years, accepted CRC screening. 9843(91.65%)persons received 3 times of fecal occult blood test. The number of positive cases was 2709(27.52%). 260 positive cases(9.6%) received colonoscopy. Results In 260 persons examined by colonoscopy, 12 patients (8men and 4 women)with CRC were detected, aged 66~77 years, including 2 polyp carcinogenesis, 2 rectal carcinoid (early stage), 4 CRC of Duke II, 1 CRC of Duke IIIA. 127 patients with colonic adenoma were detected. The rate of detection of CRC was 121.9/105. Conclusion The incidence of CRC in middle aged and old aged in urban population was rising sharply. After screening using fecal occult blood test, patients who have positive results should be examined by colonoscopy and early CRC can be detected. We suggest that this work should be performed widely in urban population to improve the prognosis of CRC.
