The present invention encompasses useful products in the treatment of cancer formed by processes utilizing physical and immunologic therapies for the treatment of neoplasms. Products for encouraging host immune responses are formed by conditioning a neoplastic tissue mass with an immunoadjuvant (also called immunomodulator or immunopotentiator) and then physically destroying the conditioned neoplasm in the presence of the immunoadjuvant. Tumor specific antibodies and antigen/antibody complexes are isolated and utilized.
