title: Clinical radioimmunodetection of cancer with radioactive antibodies to human chorionic gonadotropin.
abstract: Injection of iodine-131-labeled goat immunoglobulin G antibody to human chorionic gonadotropin (hCG) into patients with hCG-secreting trophoblastic and germinal tumors permitted tumor detection and location by external gamma-ray scintigraphy. Excision of one of the metastatic tumors located by this method indicated a tumor/nontumor ration of 39.29. The method appears to offer a new clinical tool for precisely locating hCG-producing tumors in the body, even when tumor identification by other clinical methods has failed.
