[Lack of effect of therapy with LHRH analogs, alone or associated with flutamide, on prolactin levels in advanced prostatic carcinoma].

Fourteen patients with advanced prostatic carcinoma have been considered. Some were treated with goserelin depot and some with goserelin depot plus flutamide; basal and stimulated PRL were studied in the two groups before and after two months treatment in order to verify a possible interference with prolactin secretion which seems to have a trophic and stimulating effect on neoplastic tissue growth. Basal PRL levels and levels after TRH infusion haven't shown significant variations between the two groups of patients. Even if relative to a short time, our results exclude PRL increase, which might be suspected with these drugs, and at last confirm the effectiveness of this treatment (LHRH analogs plus flutamide) in prostatic carcinoma.
