Purpose: To evaluate adherence to abiraterone or enzalutamide for the treatment of metastatic castration-resistant prostate cancer (mCRPC).
Methods: In an observational prospective cohort study, we monitored patients with mCRPC for their adherence to abiraterone or enzalutamide in the pre- or post-chemotherapy setting.
Results: Fifty-eight patients with median age of 76 years (range 56-94), age-adjusted Charlson comorbidity score of 10 (range, 4-15), and geriatric G8 score of 14 (range, 6-17) were enrolled.
