Popis: | Urinary estradiol production rates were found to be elevated in 6 consecutive men with gonadotropin-producing tumors (4 with choriocarcinoma, and 2 with ectopic gonadotropinproducing tumors of stomach and lung). The ranged from 63 to 605 μg/day (1½- to 15-fold elevated) and correlated with gonadotropin production and tumor mass. To determine the origin of the elevated E2, 3H dehydroepiandrosterone sulfate (DHEA-SO4) was given iv and its conversion to urinary E2 determined by reverse isotope methods. The transfer constant ranged from 0.5 to 11.0% and increased as the increased. Control cancer patients had ρ values of |
