Colonoscopic Biomarkers for Cancer Risk Assessment and Prevention
Subjects are randomly assigned at the time of stain-enhanced magnification colonoscopy to
have any ACF removed or merely observed. Subjects are evenly divided into those with and
those without a personal history of colon cancer. ACF are tabulated by an observer blinded
to the subject's personal history. All subjects are then re-evaluated after one year by an
observer blinded to the original procedure.
