Objectives. To affirm the feasibility of using intermittent androgen suppression in patients with hormone-naive prostate cancer.Methods. Leuprolide and flutamide were administered for 9 to 12 months and then discontinued until prostate-specific antigen (PSA) levels reached a threshold value determined by the baseline PSA value. This constituted one cycle of treatment. Androgen suppression was then administered intermittently as described until there was evidence of androgen independence.Results. Twenty-two patients with PSA failure after primary therapy with surgery and/or radiation and untreated early or Stage D2 disease were treated. Twenty-one patients completed androgen suppression during cycle 1, with a median time to PSA nadir of 3.5 months (range, 2 to 12). Fifteen patients completed cycle 1 with a median time off treatment of 6 months (range, 2 to 19) or 38% (range, 17% to 64%) of a treatment cycle. Six patients continued off treatment during cycle I for I + to 31 + months. During cycle 2, 1 2 patients achieved a PSA nadir in a median time of 3.5 months. Two patients completed cycle 2 with a median time off treatment of 10 months (51%), Median follow-up for all patients is 26 months (range, 10 to 51). While off treatment, all patients reported a reduction of symptoms associated with androgen suppression.Conclusions. Intermittent androgen suppression is a feasible alternative to continuous androgen suppression for treatment of prostate cancer, and duality of life is improved while off treatment.
