Radioimmunoimaging of metastatic medullary carcinoma of the thyroid gland using an indium-111-labeled monoclonal antibody to CEA
Elevated levels of carcinoembryonic antigen (CEA) or calcitonin after surgical therapy for medullary carcinoma of the thyroid gland (MCT) indicate the presence of residual or metastatic disease. CEA elevations appear to be prognostically more reliable in patients with metastatic disease and suggest a more virulent tumor. Attempts to stage the disease with use of conventional imaging techniques are usually inadequate, as is the therapy for disseminated or recurrent MCT. An indium-111-labeled anti-CEA monoclonal antibody (ZCE-025) was used to image metastases in a patient with MCT. Potential applications of monoclonal antibody technology in the management of MCT would include (1) preoperative differentiation of unicentric from multicentric thyroid gland involvement, (2) detection of regional or distant metastases or both, (3) measurement of response to systemic therapy, and (4) the facilitation of radionuclide immunoconjugate therapy.
