Anandron (RU 23908) associated with orchiectomy in stage D prostate cancer. Preliminary results of a randomized,...

A randomized, double-blind, multicenter trial was performed comparing the association of orchiectomy plus the nonsteroid antiandrogen Anandron (300 mg daily) to orchiectomy plus placebo in the treatment of patients with stage C or D prostate cancer. The results for 98 evaluable stage D patients with a median follow-up of 23.4 +/- 8.9 months are given. Although there was no statistically significant difference between the two treatments with regard to any parameter (subjective response, best objective response according to NPCP criteria, and progression-free interval and survival), the results were invariably in favor of the combined treatment, as already reported in other trials on Anandron.
