Adverse Effects of Androgen Deprivation Therapy on Persistent Genitourinary Complications After Carbon Ion Radiotherapy for Prostate Cancer

Additional investigation is needed to identify suitable ADT administration according to risk groups, but long-course ADT should not be adopted for non-high-risk prostate cancer patients to reduce the GU toxicity rate with C-ion RT.
