Serum alphafetoprotein (AFP) in diagnosis and management of endodermal sinus (yolk sac) tumor and mixed germ cell tumor of the ovary.
Serum AFP was determined serially by radioimmunoassay in 13 patients with ovarian germ cell tumors and in one patient with bilateral pure gonadoblastoma. There were 4 patients with pure dysgerminoma, one with pure endodermal sinus tumor (EST) and 8 with mixed germ cell tumors, all containing EST. The patients with dysgerminoma and gonadoblastoma had normal serum AFP at all times. All patients with tumors containing EST had raised serum AFP, although in most cases it was first determined between 1 and 3 weeks after operation and there was no evidence of metastases. Serum AFP became normal 5 to 7 weeks after operation and began to rise when disease recurred. Serum AFP determinations detected presence of recurrent disease long before it became detectable by other methods. Serum CEA was determined serially by radioimmunoassay in 8 of these patients, including 2 who dies with metastases, and was normal on all occasions.
