Prospective validation of microseminoprotein‐β added to the 4Kscore in predicting high‐grade prostate cancer in an international multi‐center cohort
Abstract Objectives To prospectively evaluate the performance of a prespecified statistical model based on four kallikrein markers in blood (total prostate‐specific antigen [PSA], free PSA, intact PSA, and human kallikrein‐related peptidase 2[hK2]), commercially available as the 4Kscore, in predicting Gleason grade group (GG) ≥2 prostate cancer at biopsy in an international multi‐center study at three […]
