title: [Cyproterone acetate (Androcur-depo) in the treatment of inoperable prostatic cancer].
abstract: The authors consider fundamentals of hormone therapy in prostate cancer, mechanism of long-term androgenic stimulation, detail mechanism of action of antiandrogen (ciproteron acetate-androcur) on the basis of discovered key role of cellular receptor in endocrine regulation of physiological functions in metabolism. Monotherapy with androcur-depo (300 mg once a week) was given to 24 patients with prostatic cancer stage T2-T4. Eight patients had metastases to the bones. The age of the patients ranged from 58 to 80 years. Alleviation of pain, reduction of the prostate size and density, positive uroflowmetric changes (maximal urination rate increased from 2-5 to 10-15 ml/s), residual urine fall occurred as early as treatment week 5-7. There was also a decrease in the activity of acid phosphotase from 5-10 to 0.3-0.8 units according to Bodansky. Serum level of prostate-specific antigen (PSA) dropped from 388-23 to 116-4 ng/ml. Androcur-depo monotherapy demonstrated high efficacy in the treatment of local prostatic cancer.
