Exercise Prescription Dose for Castration Resistance Prostate Cancer Patients

Recent drug improvement (e.g. abiraterone or enzalutamide) for castration resistant prostate cancer (CRPC) patients has improved survival. As treatment strategies improve and patients live longer, patients must cope with their treatment-induced adverse effects. Improving levels of physical activity (PA) and less amounts of sitting time (e.g. sedentary behavior, SB) could have a positive impact on patient's health, non-cancer mortality, and quality of life and potentially improve survival. The role of PA has not yet been examined in CRPC patients, which is a clear unmet need. No specific PA guidelines exist for CRPC patients, but specific guidelines are warranted because of advanced disease stage, reduced performance score and comorbidity. It is to be expected that the PA level of CRPC patients is lower compared to non-CRPC patients receiving androgen deprivation therapy (ADT). This study aims to determine the optimal starting physical therapy prescription in CRPC patients receiving second line hormone treatment.
