Paper Abstract

Purpose: Conventional endoscopic imaging in human colon detects large hyperplastic and adenomatous polyps (<5mm diam). However, detecting smaller early neoplastic lesions and flat adenomas is problematic. To improve the detection of such lesions we assessed the utility of fluorescence contrast agents for enhancing contrast between normal and abnormal tissues. To this end, a near infrared (NIR) fluorescent dye conjugated to a monoclonal antibody (MAb) with high affinity for a tumour-associated-glycoprotein (TAG72) antigen commonly found in colon tumours was studied as a potential fluorescence contrast agent.
