Individuals with high fecal hemoglobin concentrations detected by fecal immunochemical testing (FIT) but negative findings on high-quality colonoscopy represent a clinically challenging population. Although colonoscopy is considered the gold standard diagnostic procedure, previous studies suggest that these individuals may still have an elevated long-term risk of colorectal cancer.Read full original descriptionShow less

From Uncertainty to Evidence: A Randomized Controlled Trial for Optimal Surveillance in High-Risk Colonoscopy-Negative Individuals After Positive FIT

Individuals with high fecal hemoglobin concentrations detected by fecal immunochemical testing (FIT) but negative findings on high-quality colonoscopy represent a clinically challenging population. Although colonoscopy is considered the gold standard diagnostic procedure, previous studies suggest that these individuals may still have an elevated long-term risk of colorectal cancer.

This randomized controlled trial aims to determine the optimal surveillance strategy for this high-risk group by comparing two approaches: repeat FIT testing after two years versus direct colonoscopy after two years.

Inclusion: Age 45-74 years; Quantitative FIT result with fecal hemoglobin ≥100 µg/g within the past two years; Negative high-quality colonoscopy following the positive FIT result; Ability to provide written informed consent.

Exclusion: History of colorectal cancer; Inflammatory bowel disease; Known hereditary colorectal cancer syndrome; Life expectancy less than five years; Inability or unwillingness to undergo colonoscopy.
