Experimental: RARP + SBRT + ADT

- Proportion of men with Grade ≥ 3 adverse events the first year [ Time Frame: 1 year ]Proportion of men with Grade ≥ 3 adverse events the first year
- Proportion of men achieving prostatic specific antigen (PSA) < 0.1 ng/ml [ Time Frame: 1 year ]Proportion of men achieving prostatic specific antigen (PSA) < 0.1 ng/ml
- Feasibility of radical prostatectomy in the oligometastatic setting [ Time Frame: 1 year ]Feasibility of radical prostatectomy in the oligometastatic setting measured as number of patients who successfully undergo radical prostatectomy with pelvic lymphnode disection and 30 days (post-operative) morbidity according to the Clavian Dindo Classification.
- Time to castrate resistance (TCR) [ Time Frame: 5 yrs ]Time to castrate resistance (TCR) measured from the primary initiation of ADT to Castrate Resistant Prostate Cancer (CRPC) defined as: Three consecutive rises in PSA one week apart resulting in two 50% increases over the nadir, with PSA > 1 ng/mL or the appearance of two or more new bone lesions on bone scan or enlargement of a soft tissue lesion using RECIST. At the same time serum testosterone is <50ng/dL (<1.70 nnmol/L).
- Quality of life (FACT-P-DK) [ Time Frame: 5 yrs ]
Changes in Quality of life assessed by the questionaire FACT-P-DK and calculated using the FACT-P Scoring Guidelines (Version 4). The following scores will be evaluated:
- FACT-P Trial Outcome Index (TOI). Score range: 0-104 (The higher score the better). Combines the subscales "Physical well-being", "Functional Well-being" and "Prostate Cancer Subscale"
- FACT-G total score. Score range: 0-108 (the higher score the better QoL). Combines the subscales: "Physical well-being", "Social well-being", "Emotional well-being" and "Functional well-being".
- FACT-P total score. Score range: 0-156 (the higher score the better QoL). Combines the subscales: "Physical well-being", "Social well-being", "Emotional well-being", "Prostate Cancer Subscale" and "Functional well-being".
- Number of participants with Interventions on lower or upper urinary tract [ Time Frame: 5 yrs ]
Number of participants undergoing with interventions on lower or upper urinary tract, i.e.:
- Bladder catheter
- Ureteric stent
- Nephrostomy
- Transurethral resection of the prostate (TURP) or related procedure
