Patients and Methods: Patients diagnosed with mCPRC not previously treated with chemotherapy and administered with AA+P were classified into two groups: those with lower and higher survival rates (at 30 months vs. 60 months). Results: A total of 53 patients were studied at the time of mCRPC diagnosis. Patients with the highest survival rate had suffered prostate cancer for >45 months. At the time of initial prostate cancer diagnosis, they belonged to the risk groups 1-4, had pain intensity measured according to the brief pain inventory (BPI) scale of 0-2, were treated with AA+P>16 months, and had the following tumour marker serum levels: LDH baseline 45 months.
