Official title

Colonoscopic Biomarkers for Cancer Risk Assessment and Prevention

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

We hypothesized that aberrant crypt foci (ACF) are precursors of colon cancer; their prevention would correlate with cancer risk and their elimination would reduce that risk. In this study we wished to (1) establish the feasibility of stain-enhanced magnification colonoscopy, (2) determine whether colorectal cancer is asociated with increased numbers of ACF, and (3) investigate the natural history of ACF and the durability of their elimination.
