Over the past 10 years, the Radiation Therapy Oncology Group has evaluated, by Phase III trials, the value of using a combination regimen, including androgen suppression (goserelin [Zoladex] and flutamide [Eulexin]) and radiation therapy, in locally advanced prostate cancer. Androgen suppression prior to or during radiation has not been shown to increase overall survival, but it has been shown to increase progression-free survival and freedom from distant metastases. In addition, a subset of men with poorly differentiated tumors who received goserelin following external beam radiation have had a significant overall survival benefit at 5 years’ follow-up.
