The study indicates that adding metastasis-directed therapy with stereotactic body radiotherapy (SBRT) to standard systemic therapy for oligometastatic castration-resistant prostate cancer (CRPC) significantly improves oncologic outcomes.
100 patients with oligometastatic CRPC of whom 48 were randomly assigned to receive enzalutamide and androgen deprivation therapy (ADT) and 52 to receive enzalutamide plus ADT and SBRT.
The safety profile of SBRT with enzalutamide plus ADT was consistent with the safety profile of enzalutamide plus ADT.
