These parameters include age, preoperative serum prostate-specific antigen (PSA) concentration, body mass index (BMI), tumor diameter, Grade group (GG) and Gleason score (GS), lymphatic, venous, perineural, and seminal vesicle invasion, extraprostatic extension (EPE) of the tumor, positive surgical margins, and lymph node metastasis (10). Here, KLK3 is linked to neoplasm.
