The management and prognosis of human chorionic gonadotropin-producing seminoma still are controversial issues. In a review of 210 patients irradiated between 1950 and 1982, 10 had elevated human chorionic gonadotropin values: 3 with stage I, 6 with stage II and 1 with stage IV disease. All human chorionic gonadotropin values became negative: 4 postoperatively and 6 following radiotherapy. All patients are well with a mean followup of 6 years. One patient who suffered liver metastases only was salvaged by chemotherapy. Based on these patients human chorionic gonadotropin production is not an unfavorable prognostic sign in cases of pure seminoma.
