[Prostatic growth factors and benign hypertrophy of the prostate. Current knowledge and perspectives].

The importance of growth factors in prostatic regulation has been demonstrated for several years. These "prostatic" growth factors are ubiquitous polypeptides which are not specific to the prostate. To date, three principal families of growth factors appear to be potentially involved in the development of benign prostatic hypertrophy: Epidermal Growth Factor (EGF), Fibroblast Growth Factor (FGF), Transforming Growth Factor beta (TGF beta). The FGF and TGF beta families probably play a central role in the pathogenesis of benign prostatic hypertrophy. A better definition of the respective roles of growth factors and androgens in the control of prostatic growth opens up prospects for the future in the field of basic treatment of benign prostatic hypertrophy.
