Results From 2013 to 2021,a total of 172,244 permanent residents aged 50-74 years old were carried out colorectal cancer screening in Jinshan district.The positive rate of primary screening was 24.28%,of which 25.73% was males and 23.34% was females.They had statistically significant(χ²=127.145,P＜0.001).A total of 16,714 residents with positive screening results underwent colonoscopy,and the colonoscopy rate was 39.97%,including 40.28% for males and 39.74% for females.There was no significant difference in colonoscopy rates between the two genders(χ²=1.258,P=0.262).In the past 9 years,a total of 90 cases of colorectal cancer were detected through colonoscopy,with a detection rate of 0.54%,and 2,974 cases of precancerous lesions were detected,with a detection rate of 17.79%.There was a significant difference in the distribution of colonoscopy diagnosis results between males and females(χ²=747.903,P＜0.001)and there were also significant differences in the distribution of colonoscopy diagnosis results among residents of different age groups(χ²=111.769,P＜0.001).
