Cure8 research brief
Better triage methods that combine FIT with demographics and blood biomarkers could reduce unnecessary colonoscopies while keeping sensitivity for colorectal cancer and other serious findings, which matters for symptomatic patients and healthcare capacity.
For people with IBD or symptoms that prompt urgent referral, improved selection could speed diagnosis for those most likely to benefit from colonoscopy.
Clinicians and endoscopy services involved in urgent cancer referral pathways; researchers developing diagnostic triage tools; symptomatic adult patients referred for colonoscopy.
This abstract reports a preprint study evaluating multivariable triage models that combine fecal immunochemical test (FIT) results with demographics and blood biomarkers to select symptomatic patients for colonoscopy in an urgent cancer pathway.
The study used clinical samples collected before colonoscopy and internally validated models (5-fold cross-validation). One model added age/sex to FIT and an extended model added blood biomarkers; performance was assessed by AUC and by estimating specificity and colonoscopy reduction at fixed sensitivities.
The study cohort included 1,586 symptomatic patients with 84 colorectal cancers, 111 advanced adenomas, and 29 inflammatory bowel disease cases detected at colonoscopy. The FIT-plus-demographics model had a higher AUC than FIT alone according to the abstract. This is a structured abstract of a preprint; Cure8 did not review a full peer-reviewed paper.
Interpret the reported performance as preliminary and awaiting peer review and external validation.
This source is a preprint/abstract (structured content depth: abstract). Results are internally validated but require external validation and peer review before clinical adoption. The abstract reports AUC and colonoscopy-reduction estimates but not full study details or prospective impact on clinical outcomes.

This study highlights factors—tumor location, age, smoking, and having IBD—that were associated with survival and progression in a Lebanese CRC cohort.
This study helps distinguish patterns of colorectal dysplasia seen in people without IBD from those seen in IBD, which may affect how pathologists and clinicians interpret biopsy findings and consider cancer risk and...
Noninvasive blood biomarkers that track IBD activity could reduce reliance on repeat endoscopy. If validated, serum galectin‑3 might complement fecal calprotectin and CRP to help identify active disease.
