Abstract: A method for inducing or enhancing in a human subject the production of antibodies reactive with the polypeptide subunit of Urinary Tumor Associated Antigen having a molecular weight of about 90 to 100 kD after reduction by .beta.-mercaptoethanol and separation by SDS-polyacrylamide gel electrophoresis is disclosed. The method comprises administering to the subject an effective dose of a composition comprising inactivated tumor cells having Urinary Tumor Associated Antigen on the cell surface and at least one tumor associated antigen selected from the group consisting of GM-2, GD-2, Fetal Antigen and Melanoma Associated Antigen.
