According to some studies [16,17], the intensity of intraprostatic PSMA uptake (SUVmax) reflects underlying tumor aggressiveness, showing strong correlations with PI-RADS score and histologic grade at diagnosis, and acting as an independent predictor of biochemical recurrence after radical prostatectomy, even when adjusted for PSA level, Gleason score, and pathological stage. Here, KLK3 is linked to neoplasm.
