To determine if the use of Prostate-Specific Membrane Antigen Positron Emission Computer Tomography (PSMA PET/CT) as a selection tool for performing extended lymph node dissection (ePLND) for prostate cancer (PCa) in the primary staging setting results in fewer ePLND procedures and therefore lower overall healthcare costs, lower patient burden in terms of intervention-related complications and morbidity, with comparable disease prognosis, compared to the current European Guideline-recommended standard practice which includes performing ePLND in PCa patients who are candidates for active treatment with a nomogram-calculated lymph node involvement (LNI) risk \>5%.
