But étude The purpose of this study is to determine if plus releasing hormone (GnRH) agonist in participants with high-risk, localized or locally advanced receiving primary radiation therapy results in an improvement of metastasis-free survival.

Critères d'éligibilité Each potential subject must satisfy all of the following criteria to be enrolled in the study. Subject must be a man ≥18 years of age Each subject must sign an informed consent form (ICF) indicating that he understands the purpose of and procedures required for the study and is willing to participate in the study.
