• Patient with a history of local treatment with curative intent for localised prostate cancer, including surgery or radiotherapy.
• Patients with castration resistant prostate cancer, defined as either:
  • An increasing PSA level, confirmed in 3 consecutive assessments performed at least 1 week apart. This despite androgen deprivation therapy and castrate levels of testosterone.
  • Tumour progression of soft tissue according to the response criteria in solid tumours (RECIST) version (v)1.1.
  • Tumour progression on bone scan, according to PCWG3 criteria.
  • N.B. The two latter conditions only apply to the M1CRPC population.
• Detection of 1 to 5 metastatic sites (pelvic lymph nodes included) on new generation PET using either choline, fluciclovine, or PSMA as tracer.
• All metastatic sites must be amenable to stereotactic radiation therapy.
• Patient with normal haematological function: absolute neutrophil count (ANC) >1.0 x 10⁹/L, platelets count ≥100 x 10⁹/L, and haemoglobin ≥9.0 g/dL.
• Patient with normal liver function with total bilirubin ≤1.5 upper limit of normal (ULN) (unless documented Gilbert's syndrome), aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) ≤2.5 ULN (≤5 ULN in the presence of liver metastases).
• Adequate liver function with bilirubin <3 mg/dL and albumin >2.5 g/dL.
• Systolic blood pressure <160 mmHg and diastolic blood pressure <100 mmHg, as documented at baseline. Patients with hypertension are eligible if their hypertension is controlled and they meet all other eligibility criteria.
