Recently, the cases of colorectal cancers has been rising in younger age (<50) individuals. Although current guidelines recommend colorectal cancer screening should be initiated at age 45 instead of 50, the optimal approach of colorectal cancer screening is not clear.
This article investigates the efficacy of fecal immunochemical test (FIT), which detects occult blood in stool, in predicting advanced colorectal polyps and tumors among people aged 40–49.
The findings suggest FIT is useful to identify such people with high risk to have advanced colorectal lesions. Hence, FIT may be considered as the first-line screening tool for these people, and further comparative study between FIT and colonoscopy will be of great value.
The detection rate of ACRN(advanced) and CRC based on FITs in individuals aged 40–49 years is acceptable, and the yield of ACRN might be similar between individuals aged 45–49 and 50–59 years. Further comparative and cost-effective analysis of colonoscopies is mandatory to guide its use in EOCRC screening.
