The main objective of this prospective study was to assess the value of gallium-68 prostate-specific membrane antigen ([68 Ga]Ga-PSMA-11) positron emission tomography/computed tomography (PET/CT) in primary N and M staging of intermediate- and high-risk prostate cancer (PCa) patients before planned curative-intent radical prostatectomy (RPE) and extended pelvic lymph node dissection (ePLND). Here, FOLH1 is linked to posterior cortical atrophy.
