[Primary treatment for stage D2 prostate cancer: a randomized study of combined androgen blockade alone versus combined with UFT].
To evaluate the efficacy of chemoendocrine therapy for the initial treatment of stage D2 prostate cancer, we conducted a prospective randomized study which compared combined androgen blockade alone to that combined with UFT. Twenty-one patients received LH-RH agonist and flutamide (Group-A), and 23 patients received LH-RH agonist, flutamide and UFT (Group-B). The overall response rate and the PSA response rate of Group-A was 71.4% and 100% respectively, against 65.2% and 90%, respectively in Group-B. The median follow-up period was 24 months. The 2-year progression-free survival rate of Group-A was 7.4% and that of Group-B was 15.9%. The response rate and progression-free survival rate did not differ significantly between the 2 groups. Liver dysfunction due to flutamide was common in both groups, and a total of 4 patients did not continue the treatment because of this adverse effect. We conclude that in patients with stage D2 prostate cancer, treatment with combined androgen blockade and UFT is not superior to treatment with combined androgen blockade alone.
