Goserelin acetate and flutamide versus bilateral orchiectomy : a phase III EORTIC trial (30853). Editorial comment

Maximal androgen blockade (MAB), the eradication of the effects of adrenal androgens on prostate cancer cells after castration, has been used with differing success in the treatment of prostatic carcinoma. The aim of this randomized phase III study was to compare the efficacy and side effects of bilateral orchiectomy versus a combination of a luteinizing hormone-releasing hormone agonist (LHRH-A) depot formulation, goserelin acetate (3.6 mg s.c. once every four weeks), and flutamide (250 mg three times daily), in patients with metastatic cancer. Treatment usually continued until disease progression (or for a minimum of three months). Efficacy was assessed by response, time to disease progression, and duration of survival
