About this study

The objectives of the study are to analyze the results obtained in survival, safety and quality of life after the combination of SBRT plus second-generation antiandrogen in patients diagnosed with metastatic castration-resistant prostate cancer in oligometastasis (≤5). Hence, the investigators evaluate the results of the combination of two widely used treatments in prostate cancer: SBRT plus the 'standard of care' for patients with mCRPC, second-generation antiandrogens (abiraterone and enzalutamide). Primary objective: Determine the PRFS measured from the time of initiation of second-generation antiandrogen to the time of radiological progression by choline PET/CT or 68Ga-PSMA PET/CT, in patients with mCRPC treated with the combination of second-generation antiandrogen plus SBRT. Secondary objectives: * Overall survival (time from initiation of second-generation antiandrogen to exitus) in patients with mCRPC treated with the combination of second-generation antiandrogen plus SBRT. * Quality of life of these patients using the European Organization for Research and Treatment of Cancer (EORTC) quality of life scale, EORTC QLQ-C30, validated for oncology patients. * Acute and chronic toxicity according to the "Common Terminology Criteria for Adverse Events" (CTCAEv5.0) scale. This is a phase II, multicenter, prospective, single group study in patients with castrate-resistant prostate cancer (CRPC). Patients will be recruited at the participant sites, after study approval …
