Fluorescence Endoscopy Using a Fluorescein-Labeled Monoclonal Antibody Against Carcinoembryonic Antigen in Patients with Colorectal Carcinoma and Adenoma

Abstract

Fluorescence endoscopy using fluorescein-labeled monoclonal antibody against CEA was shown to be positive in most cancers and some adenomas. Further and larger studies will be needed to demonstrate the value of this technique for differential diagnosis.
