TAG-72/CA 72-4 Information for Pathologists

Summary:

Definition: monoclonal antibody that recognizes tumor-associated glyocoprotein 72 (TAG-72), a mucin-like sugar and protein complex on the surface of many cancer cells. Antibody is directed against the Sialyl-Tn blood group antigen. Interpretation Cytoplasmic staining. Uses by pathologists

Common Uses By Pathologists:

Distinguish pulmonary adenocarcinoma (positive) from mesothelioma (negative) as part of a panel (Diagn Cytopathol 1997;17:115). Distinguish carcinoma in cytology specimens (positive) from benign effusions (usually negative, but may have focal staining, J Clin Pathol 1990;43:1026, Acta Cytol 1987;31:537, Diagn Cytopathol 2007;35:300). Confirm diagnosis of breast apocrine carcinoma (APMIS 2006;114:712).
