Oligometastatic Hormone-Sensitive Prostate Cancer. Why Radiotherapy?

Abstract

Androgen deprivation therapy (ADT) has been considered for years the standard initial treatment for patients with metastatic prostate cancer (mPC). Recently published results support the use of taxanes, second-generation antiandrogens or radiotherapy to the primary tumor as part of the treatment in these patients, considering ADT alone as suboptimal. Metastasis-directed therapy (MDT) is used as part of the treatment for oligometastatic patients in different tumor types. In oligometastatic hormone-sensitive prostate cancer the role of MDT is being studied with promising results. In the present review we assess the available evidence for radiotherapy to the primary tumor in newly diagnosed mPC and for MDT in oligometastatic prostate cancer, as well as future directions in this clinical setting.
