Abstract

Monoclonal antibodies (MAbs) which recognize a human tumor antigen, termed tumor-associated glycoprotein-72 (TAG-72), have successfully been used to localize primary as well as metastatic colorectal tumor lesions in patients. The localization of the anti-TAG-72 MAbs has also been exploited intraoperatively using a hand-held gamma probe. That procedure, termed radioimmunoguided surgery (RIGS), has identified occult tumors which were not detected using standard external imaging techniques. In another clinical trial, interferon-γ (IFN-γ) was administered intraperitoneally to patients diagnosed with either gastrointestinal or ovarian carcinoma with secondary ascites. Analysis of the tumor cells isolated from the malignant ascites revealed a substantial increase in TAG-72 expression on the surface of tumor cells isolated from seven of eight patients. The results provide evidence that the combination of an anti-carcinoma MAb with the administration of a cytokine, such as IFN-γ, may be an effective approach for the detection and subsequent treatment, of colorectal carcinoma.
