Abstract

Objective: To provide a current and evidence-based clinical review of practical value to primary care physicians encountering men with hormone-refractory prostate cancer (HRPC) in their practice.
Methods: Evidence-based narrative review by two expert clinicians incorporating results of systematic reviews and randomized trials whenever available.
Results: HRPC represents the final common pathway to death from prostate adenocarcinoma, the single most prevalent cancer in Canadian men. However, primary care physicians will not encounter these patients with a frequency adequate to develop confidence in their care. HRPC is defined by progressive disease despite castration, and biologically is a characterized by androgen hypersensitivity. It is important to understand that HRPC is a disease spectrum ranging from asymptomatic patients with only a rising prostatic-specific antigen (PSA) level and a prognosis measured in years to extremely symptomatic patients with widespread metastases requiring end-of-life care. Numerous effective management options are now available for HRPC and are selected based on the phase of the disease natural history, and patient comorbidities and preferences.
Conclusions: Men with HRPC have therapeutic options that can improve and maintain both the quality and quantity of their lives. A co-management approach including a medical oncologist and the patient's urologist and primary care physician is preferred.
