Flutamide versus stilboestrol in the management of advanced prostatic cancer. A controlled prospective study.

Summary— In a prospective randomised study the effect of flutamide 750 mg daily was compared with that of stilboestrol 3 mg daily in the treatment of 40 previously untreated patients with advanced prostatic cancer. There was a good subjective response to both treatments. After 12 months, a response was demonstrated in 13 of 20 patients treated with flutamide and 8 of 20 patients treated with stilboestrol. The difference was not statistically significant. Treatment with stilboestrol caused more frequent, and more severe, side effects than flutamide.
