title: Hormonal effects of high dose medroxyprogesterone acetate treatment in males with renal or prostatic adenocarcinoma.
abstract: In 18 patients, 12 with renal and 6 with prostatic carcinoma, the gonadal, pituitary and adrenal functions were studied by measurements of steroid hormones and gonadotrophins, before and after six weeks treatment with medroxyprogesterone acetate (MPA), injected intramuscularly 500 mg per day for 5 days each week. The testosterone-oestradiol-binding globulin (TeBg) was measured and the amount of albumin and TeBg bound and unbound testosterone was calculated. Treatment with high doses of MPA caused a profound decrease in serum concentrations of testosterone, dehydroepiandrosterone sulphate (DHEAS), cortisol and TeBg. There were significant decreases in serum concentrations of luteinizing hormone (LH), follicle stimulating hormone (FSH) and oestradiol-17 beta. The serum concentration of prolactin was significantly elevated. The protein unbound testosterone fraction was lowered by MPA treatment but less than total testosterone. In conclusion, MPA therapy in high dose alters the gonadal, pituitary and adrenal functions suppressing serum concentrations of androgens, gonadotrophins, cortisol and TeBg but elevating prolactin concentration.
