Abstract
Sera from 190 patients (including 125 patients with cancer of the digestive tract) have been investigated for the presence of circulating antibodies directed against the carcinoembryonic antigen (CEA). Use of three different techniques (passive hemagglutination, immunoadsorption and immunoftuorescence) revealed no evidence for the autoantigenicity of this particular antigen. The titers demonstrated in patients' sera were due to antibodies directed against normal tissue proteins which were present in perchloric acid extracts of colonic tumors.

Studies of immune recognition in cancer have defined several tumor antigens using autologous cytotoxic T lymphocytes and by detection of serum antibodies to tumor-associated products such as p53 and HER-2/neu. The AIS gene is a p53 homologue with multiple protein products (p40, p51, p63, p73L) on ch
CEA and cellular mucin antigens have been recognized as potential targets for specific immunotherapy and are frequently expressed in bladder cancer. We studied the coordinated expression of a bladder cancer-associated CEA glycoform and of the mucins MUC1, MUC2 and MAUB under various growth condition
