Serum from 59 men with testicular masses was examined for the presence of human chorionic gonadotropin-beta. Results indicate: 1) In patients with testicular tumor human chorionic gonadotropin-beta serves as a sensitive and specific marker of tumor activity with an incidence of 28%. 2) Because human chorionic gonadotropin-beta levels correlate with response to therapy this test will be useful in selecting men for adjunctive irradiation or chemotherapy. 3) Radioimmunoassay for human chorionic gonadotropin-beta is far more sensitive and specific than conventional methods for detecting human chorionic gonadotropin production. 4) After unilateral orchiectomy for carcinoma of the testis elevated serum luteinizing hormone levels are common and may be unrelated to the presence or activity of residual tumor. 5) Human chorionic gonadotropin-beta producing tumors were associated with increased estradiol and testosterone levels and significantly depressed serum follicle stimulating hormone levels in this series. 6) The prognostic implications of the presence of human chorionic gonadotropin beta are not yet fully understood. The importance of this study is the fact that men with testicular tumors have a high incidence of human chorionic gonadotropin-beta secretion and this fact provides the physician with a powerful new tool for examining the various aspects of tumor activity. It also shows the feasibility for prospective screening of patients with a wide variety of neoplasms of differing histologic types.
