Abstract Objective To evaluate the feasibility of colorectal cancer screening being combined with the annual physical examination in a military unit. Methods A total of 1208 people aged 40 and above received fecal occult blood test and questionnaires. Those tested positive and at risk underwent colonoscopy. Results 1045 of these people received both FOBT and the risk factor survey,the response rate being 86.5%. 25 people got positive results in FOBT, 21 underwent colonoscopy, 118 people got positive results in the risk factor survey and 83 people underwent colonoscopy.There was no statistical difference between the two groups in the response rate of colonoscopy,positive rate of colonoscopy, detection rate of cancer,or detection rate of ademoma with atypical hyperplasia. The detection rate of villous adenoma and multiple tubular adenoma was higher in FOBT positive group than in survey group（P＜0.05）while the detection rate of solitary adenoma was higher in survey group than in FOBT positive group（P＜0.05）. Conclusion The response rate is higher in the protocol of colorectal cancer screening accompanied by annual physical examinations. The risk factor survey is an efficient method in colorectal cancer screening.
