The aim of this thesis was to assess the impact of intensive hormonal therapy prior to radical prostatectomy in high-risk prostate cancer (PCa) in order to optimise the outcome of this patient population. Next, the recurrence patterns of PCa patients with prostate-specific antigen (PSA) relapse following localised therapy were assessed using novel imaging techniques such as prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT). Moreover, the safety and oncological outcomes of PCa men with oligometastatic recurrence (1–5 lesions) following localised therapy treated with metastasis-directed therapy were investigated. Lastly, the safety and efficacy of radium-223 in men with PSA relapse following localised therapy without visible lesions on PSMA PET/CT were assessed.
