Accuracy of fecal immunochemical tests for detecting advanced colorectal neoplasia at surveillance colonoscopy.

Key Points

• The central aim is to evaluate the accuracy of fecal immunochemical tests for detecting advanced colorectal neoplasia at surveillance colonoscopy.
• Evaluated the sensitivity of fecal immunochemical tests with a lowered hemoglobin cutoff.
• Assessed the impact of serial testing on detection rates.
• Analyzed potential changes in surveillance strategies based on FIT results.
• Lowering the FIT hemoglobin cutoff significantly enhanced sensitivity for detecting advanced lesions.
• Serial testing could further improve detection rates.
• FIT-based surveillance may serve as an alternative to traditional colonoscopy procedures.
