Scenario 1 considered all postoperatively available parameters such as preoperative PSA level, pathological tumor stage (pT), pathological Gleason grade based on morphological analysis of the entire prostatectomy specimen, pathological lymph node status (pN), surgical margin status (R), and JUP expression (overall 6521 samples analyzable with 3033 of them with known ERG‐negative and 2363 with known ERG‐positive status; Table 5). Here, ERG is linked to neoplasm.
