Spectroscopic detection of colon polyps (Spy Colonic Neoplasia)


The purpose of this study is to determine if colon cancer or precancerous colon polyps can be predicted from examining the lining of the rectum with a special harmless light. If so, primary care physicians will be able to determine from this simple test which of their patients actually needs a colonoscopy instead of referring 100% of their patients simply because they turn 50 years old.

About This Study

The goal of this study is to determine if a special light delivered by a thin optical probe can detect precancerous changes in the colon. The light is passed through a computer that analyzes the light to determine if the person’s colon contains a cancer or growths called polyps that can become a colon cancer. We hope this simple device will predict the presence of colon cancer or precancerous colon polyps more accurately than current methods.
