  • Title: Immunoscintigraphy in medullary thyroid cancer using an 123I- or 111In-labelled monoclonal anti-CEA antibody fragment.
    Author: Reiners C, Eilles C, Spiegel W, Becker W, Börner W.
    Journal: Nuklearmedizin; 1986 Dec; 25(6):227-31. PubMed ID: 3808964.
    Abstract:
    The monoclonal anti-CEA F(ab')2 fragment MAb BW 431/31, labelled with 123I or 111In, was used for immunoscintigraphy (IS) in 9 patients with medullary cancer of the thyroid (CCC). The results of 11 studies lead to the following conclusions: When using radioiodine as a label for MAb in IS, potassium iodide is absolutely necessary to block the thyroid which is of special importance in patients with thyroid cancer; Preinjection of "cold" MAb reduces the relatively high unspecific uptake (especially in bone marrow) of MAb BW 431/31, which is of special importance for the antibody labelled with 111In; IS with MAb BW 413/31 in patients with CCC and elevated serum CEA is positive only in cases with large secondaries; and In patients with CCC and several manifestations of secondaries, only a single (large) metastasis may be apparent.
