The results of a randomized, multicenter, cooperative group trial evaluating hormonal therapy with either megestrol acetate or dexamethasone in advanced, hormonally refractory prostate cancer are reported. Three of 29 patients (∼10%) on the megestrol acetate arm experienced an objective response lasting 41, 84, and 202 days, respectively, whereas two of 29 patients (∼7%) on the dexamethasone arm achieved an objective response lasting 359 and 512 days, respectively. Twenty of 29 patients (∼69%) on the megestrol acetate arm had stable disease lasting for a median duration of 117 days, whereas 21 of 29 patients (72%) on the dexamethasone arm had stable disease for a median duration of 86 days. Median survival of all patients was 9 months from initiation of treatment. The median survival for patients on the megestrol acetate arm was 268 days compared to 246 days for patients on the dexamethasone arm (P = 0.2). Neither dexamethasone nor megestrol acetate would seem to be of substantive value in altering the progression of advanced, hormonally refractory prostate cancer.
