underwent FIT following two previous negative tests.The proportion of SD lesions located in the proximal colon was 71.3% for CRC and 56.1% for advanced adenomas.CONCLUSION: One FIT could detect some proximal lesions among people with negative FS.The optimal interval between FS and FIT and the cost effectiveness ratio of this strategy need to be assessed.
