This clinical trial is for patients with Advanced Prostate Cancer. The purpose of this study is to learn more about prostate cancer and:

• To describe the use of different therapies for advanced prostate cancer internationally; 
• To describe specific treatment patterns and whether they are associated with differences in outcomes such as hospitalizations 
• To identify associations between treatment sequences or combinations and overall survival; 
• To define the patient experience of men with advanced prostate cancer and identify unmet needs in their treatment; 
• To identify clinical and molecular disease subtypes that may predict for a reduction in cancer from individual treatments, combinations, or sequences. 

Outline of the study includes a baseline (demographic data, epidemiological data, treatment history, clinical and pathology, patient reported outcomes and physician questionnaire), and follow-up visit for a minimum of three years (follow-up bloods, patient reported outcomes, physician questionnaire, and clinical follow-up data)
