Abstract
Results obtained from studies using experimental animal model clearly showed that (1) A marker(s) for CCA does exist; 2) This marker is a glycoprotein with a molecular weight of 200 kDa; (3) It is produced and secreted in vitro by tumor cell lines; (4) It is highly immunogenic in mice and the MAb specific for this antigen is directed against the carbohydrate moiety; (5) This tumor antigen can be detected in serum and bile of tumor-bearing animals by a sandwich ELISA employing this MAb; (6) Kinetic studies show a gradual elevation of this antigen during tumor development; and (7) The elevation of this antigen can be detected at a time when no pathological changes have yet taken place, as judged by microscopic examination. Preliminary work from the human counterpart using human cholangiocarcinoma cell line showed promising results. CCA-specific antigen could be similarly identified and the MAbs produced were highly specific for this 160 kDa antigen.
