New study reveals best way to spot dangerous colon growths
NCT ID NCT01521091
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared three methods used during colonoscopy to predict whether colorectal growths are cancerous: narrow band imaging (NBI), indigo carmine staining, and acetic acid staining. Researchers studied 565 patients with at least one lesion 6mm or larger. The goal was to see which method most accurately identifies invasive cancer. Results suggest NBI may be the best first choice.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- narrow band imaging, indigo carmine, and acetic acid staining
- What this could lead to
- If successful, this could help doctors choose the best method to accurately diagnose colorectal lesions during colonoscopy, potentially reducing unnecessary biopsies.
- What could go wrong
- This is a completed diagnostic accuracy study, not a treatment trial. Results may not apply to all patients or settings, and the methods require specialized equipment and training.
