Biochemical recurrence of pathological T2+ localized prostate cancer after robotic-assisted radical prostatectomy: A 10-year surveillance

Figure 1 Receiver operating characteristic curve showing meaningful prostate specific antigen cut-off value (arrow). Cut-off value: 19.09 ng/mL; sensitivity: 0.600, specificity: 0.739.

Figure 2 Distributions divided by prostate specific antigen intervals in biochemical recurrence and non-biochemical recurrence groups. PSA: Prostate specific antigen; BCR: Biochemical recurrence.

Figure 3 Linear regression model between preoperative prostate specific antigen and time to biochemical recurrence. Pearson’s correlation: 0.13; adjusted R² = 0.026. PSA: Prostate specific antigen; BCR: Biochemical recurrence.
