in order to examine the relative usefulness of measurements of oncoplacental proteins as tumor markers in patients with nonseminomatous germ cell tumors , the authors measured alpha-fetoprotein ( afp ) , human chorionic gonadotropin ( hcg ) , pregnancy-specific beta 1-glycoprotein ( sp1 ) , human placental lactogen ( hpl ) , and placental cystine aminopeptidase ( oxytocinase , cap ) in serial blood samples obtained from 26 men with these neoplasms .
