[Surgical or medical castration with LH-RH analogue for prostatic cancer].

Since the discovery by Huggins and Hodges that androgen deprivation therapy is effective for prostatic cancer, surgical castration or the administration of exogenous estrogen has been the mainstay of treatment for advanced prostatic cancer. However, surgical castration is refused by some patients because of psychological impact and estrogen therapy is reported to be associated with significant morbidity and mortality. The chronic administration of superactive analogue of LHRH has been shown to suppress markedly gonadal steroidogenesis. Medical castration with LHRH analogue has been demonstrated to be safe and effective in patients with advanced prostatic cancer. But the traditional surgical castration still remains as another powerful option, because it is more excellent in the points of compliance and cost-benefit than a monthly injection of expensive LH-RH analogue.
