[Plasma testosterone: a sound criterion of the effectiveness of hormonal treatment of prostatic carcinoma].

Plasma concentrations of testosteron, LH, FSH were repeatedly followed up during a three-year hormonal treatment in 40 patients with comfirmed prostate carcinoma. The initial concentrations of the indicated hormones were established not to differ statistically from their levels in intact subjects and cannot serve as diagnostic criteria. With a drop of testosteron concentration under 70 per cent from the initial level, the treatment with hormonal preparations could be admitted successful and with a drop to 10 per cent--a maintaining therapy should be followed.
