[Clinical significance of prostatic exosomal protein and PSA in detecting prostate cancer with the PSA gray zone and PI-RADS-3 lesions].

For patients with the PSA gray zone and PI-RADS-3 lesions, f/tPSA and PSEP are significant predictors of PCa. The multivariate model of PSEP combined with f/tPSA can replace f/tPSA in the detection of PCa to improve diagnostic performance and avoid unnecessary prostate biopsy.
