目的了解嘉定区居民大肠癌筛查的检出率，并通过实践评估大肠癌筛查实施效果。方法对嘉定区常住人口中50岁以上并参加本区各类医疗保障的退休人员，采用危险度评估和粪便潜血试验(FOBT)检查相结合的方式进行初筛，初筛阳性者进行全结肠镜检查。结果嘉定区共有77653人参与初筛，初筛阳性率为24.85%；肠镜检查人数7143人，肠镜检出率为25.07%，其中男性检出率26.05%，女性检出率24.46%，差异无统计学意义(X2=2.283=0.131)；年龄分组中，50~59岁组检出率最低15.98%，且随年龄增加检出率逐年增高，70岁及以上最高为30.32%，差异有统计学意义(X2=189.21<0.001)；本次筛查共检出大肠癌患者70例，早期率达到43.33%。结论开展社区居民大肠癌筛查有利于提高大肠癌早期发现率，降低发病率和死亡率上升，值得在社区推广。“,”Objective Understand the detection rate of colorectal cancer screening, Jiading district, residents and evaluation of colorectal cancer screening ef ect through practice. Methods Jiading district, the population of permanent residents in more than 50, and participate in al kinds of health care in this area of the retirees, using risk assessment and fecal occult blood test (FOBT) check the combination of early screening, early screening positive for a colonoscopy. Results Jiading district, the results of a total of 77653 people participate in early screening, early screening positive rate is 24.85%;Endoscopic check number 7143 people, colonoscopy detection rate was 25.07%, and a detection rate of 26.05%of men, women, detection rate of 24.46%, there was no statistical y significant dif erence (χ2=2.283, =2.283);Age group, 15.98%detection rate minimum 50 to 59 years old group, and increase the detection rate increased year by year, along with the age 70 and older as high as 30.32%, the dif erence was statistical y significant (χ2=189.21, <0.001);The 70 cases with detection in patients with colorectal cancer screening, early rate reached 43.33%. Conclusion To car y out the community residents is beneficial to increase the rate of early detection of colorectal cancer, colorectal cancer screening to reduce morbidity and mortality, is worth popularizing in the community.
