An anti-CEA monoclonal antibody (FO23C5), belonging to the IgG1a class, was used to perform several preclinical and clinical studies on radioimmunoscintigraphy (RIS) in patients with colorectal carcinoma. Preliminary screening on different tissues showed high specificity of this antibody for gastric and colorectal carcinomas. A pilot study on 51 patients with 64 localizations of colorectal carcinoma was realized, followed by a multicenter validation study in which, among 509 patients bearing CEA secreting tumors, 254 patients had primary or relapsed colorectal tumors. High sensitivity and specificity values were obtained by these studies and many "unsuspected" localizations were recorded. In order to better define the clinical utility of this approach, a prospective trial was run on 59 patients previously submitted to surgery for colorectal carcinoma and with suspected local relapses. A comparative evaluation of RIS, CT scan, US and MRI was performed. RIS and MRI have the highest value of accuracy (86%) followed by CT scan (68%) and US (54%). No adverse reactions were noticed in any of the patients examined.
