Whether PSMP in serum and urine from PCa patients could be used as a diagnostic biomarker PCa compared with PSA was confirmed in another set of collected samples. (A–C) Total PSA, free PSA, and total/free PSA in serum from the BPH group, medium Gleason score group, and high Gleason score group were measured and analyzed. (D) Sensitivity and specificity of total/free PSA as a diagnostic biomarker were analyzed by an ROC curve. (E,F) Serum and urine PSMP levels in the BPH group, medium Gleason score group, and high Gleason score group were measured and analyzed. (G,H) Sensitivity and specificity of serum and urine PSMP as diagnostic biomarkers were analyzed by ROC curves.
