Prostate cancer (PCa) is the most common type of cancer to affect men and, unfortunately, for the majority of PCa patients, death is attributed to metastatic disease. Lifelong androgen deprivation therapy (ADT) with LHRH agonists can help delay cancer progression in metastatic PCa patients. However, patients eventually become castration-resistant (disease progression despite ADT) and develop progressive metastatic disease. This in turn impacts the patient's quality of life and survival. Recently, a new generation of hormonal therapy (such as Enzalutamide) has become available to these castration-resistant prostate cancer (CRPC) patients. We believe that the benefits from this new generation of hormonal therapy can be prolonged in CRPC patients who develop oligometastases by treating the metastatic lesions using stereotactic body radiotherapy (SBRT). This new radiation technique allows for the treatment of many different metastases throughout the body in a very precise manner. This metastases-directed therapy is a new treatment option for patients with a limited number of metastases (less than 5) at the time of recurrence.
