title: Bicalutamide: a new antiandrogen for use in combination with castration for patients with advanced prostate cancer.
abstract: Maximum androgen blockade, a relatively recent development in the treatment of prostate cancer, combines medical or surgical castration with antiandrogen therapy. A large randomized study comparing the non-steroidal antiandrogen, bicalutamide, with flutamide, each in combination with luteinizing hormone-releasing hormone (LHRH) analogs, showed that after a median follow-up of 49 weeks, the time to treatment failure was significantly longer for the bicalutamide patients compared with the flutamide patients (p = 0.005). After a median follow up to 95 weeks, bicalutamide in combination with LHRH analog therapy produced at least equivalent efficacy with flutamide in combination with LHRH analog therapy in terms of time to treatment failure and equivalent efficacy in terms of survival. The tolerability profile of bicalutamide, as based on reported findings and a literature review, indicates a superior tolerability to that of currently available antiandrogens, particularly with respect to diarrhea with a low incidence of treatment-related withdrawals.
