The serum PSA-Gi levels at Pbx in PCa patients who underwent radical prostatectomy (RP). (a) PSA-Gi levels before Pbx among PCa patients classified by the Pbx grade group (Pbx GG); (b) total PSA level before Pbx of PCa patients classified by the Pbx GG. Cutoff levels at 57.1% sensitivity of PSA-Gi and/or total PSA is presented as a blue dotted line; (c) ROC curve analysis of total PSA and PSA-Gi in PCa patients with Pbx GG 2 and Pbx GG 3. The AUCs for the prediction of patients with Pbx GG 3 of PSA-Gi and total PSA were 0.649 and 0.520, respectively.
