Transdermal Estradiol and Exercise in Mitigating Adverse Effects of Androgen Deprivation Therapy for Prostate Cancer Radiation Therapy

The goal of the clinical trial is to find out whether transdermal estradiol will reduce the adverse effects of androgen deprivation therapy in prostate cancer patients. The primary aim of this study is to estimate the efficacy of transdermal estradiol (E2) in reducing androgen deprivation therapy induced adverse effects on sexual function. A secondary aim of this study is to estimate the utility of E2 and the combination of E2 with supervised exercise in reducing other androgen deprivation therapy related adverse effects. Participants (n=310) will use transdermal estradiol for 12 months concomitant to androgen deprivation therapy. The use of transdermal estradiol will start at the beginning of the trial, at the same time as androgen deprivation therapy. A subgroup of participants (n=120) will also be allocated to perform six months supervised resistance training. Researchers will compare transdermal estradiol group to control group, and resistance training groups and non-training control groups.
