FOLH1 and metastatic neoplasm: Mean PSA at time of PSMA scanning for those 20 patients who underwent lymphadenectomy was 2.49 (n = 20, range 0.21–12.0), compared with mean PSA 0.4 for the group who had negative PSMA scans (n = 21, range 0.1–1.0) and mean PSA of 5.45 for those patients who underwent treatment other than pelvic LN clearance (n = 25, range 0.2–19.0 including 19 patients with metastatic disease beyond pelvic LN) (Table 1).
