Figure 2From: Comparison of biochemical failure rates between permanent prostate brachytherapy and radical retropubic prostatectomy as a function of posttherapy PSA nadir plus ‘X’Biochemical Failure (BF) as a Function of Prostate-Specific Antigen (PSA) Nadir + X. Graph shows Kaplan-Meier estimated 5-year rate of BF in patients treated with permanent prostate brachytherapy (PPB; n = 291) and radical retropubic prostatectomy (RRP; n = 873) for different definitions of PSA nadir + X. The X-axis shows the value of “X” ng/mL PSA in the equation “PSA nadir + X.”Back to article page
