title: Human chorionic gonadotropin-positive seminoma: is this a special type of seminoma with a poor prognosis?
abstract: Prognosis and treatment of HCG-positive seminomas with syncytiotrophoblastic giant cells are still a matter of discussion. Between 1977 and 1982 the serum HCG and alpha-feto protein levels were determined in a prospective study of a total of 51 patients presenting with histologically proven pure seminomas. A total of 13 of the 51 patients with pure seminoma had elevated serum HCG levels, but all of them were negative for alpha-feto protein. On clinical examination six patients had tumor Stage I, six had had tuor Stage II A-B and one patient had a tumor Stage III. The clinical stage was not found to correlate with HCG levels. In six patients presenting with tumors of clinical Stage II who underwent orchiectomy and subsequently radiation therapy there was a decrease in HCG levels following therapy. Five patients were followed for five years after therapy had been discontinued. There is no indication of a relapse in four patients, and the patients are negative or HCG. One patient suffering from a tumor, Stage IIB died three years later as a result of cirhosis of the liver. Autopsy did not reveal any signs of a residual tumor; the serum HCG levels were negative. For the time being HCG-positive seminomas should be classified and treated as a special morphologic form of seminoma.
