If you are assigned to Group 2, you will receive the same radiation therapy as participants in Group 1, but you will also receive hormone therapy with bicalutamide (Casodex) and either leuprolide (Lupron) or goserelin (Zoladex). The hormone therapy includes a total of 2 injections or shots (leuprolide or goserelin) given every 3 months and a pill (bicalutamide) that is taken once per day for the first 21 to 30 days. Flutamide, which is taken three times per day for the first 21-30 days, may be used instead of bicalutamide. The choice of hormone therapy will be left up to your treating physician. You will receive hormone therapy for a full 6 months. Hormonal treatment will begin about 2 months before radiation therapy is due to start and continue for 2 months during radiation therapy, with the last phase of hormone treatment for 2 months after radiation therapy.
