Abstract
Studies in both patients and mice have been carried out using heterologous antibody directed at secreted products of tumors. In preliminary therapeutic studies in patients with drug-resistant choriocarcinoma and malignant teratoma, heterologous anti-human chorionic gonadotrophin (HCG) and anti-alpha-fetoprotein have been combined with continued cytotoxic chemotherapy. The results to date, although interesting, are inconclusive. In nude mice, anti-HCG administration at the time of inoculation with choriocarcinoma cells failed to inhibit tumor growth. 131I-Labeled anti-HCG and anti-carcinoembryonic antigen have been used in localization studies. Specific:nonspecific ratios of up to 2:1 were obtained in human and murine studies with HCG- and carcinoembryonic antigen-producing tumors.
