From: Direct comparison of low-dose-rate brachytherapy versus radical prostatectomy using the surgical definition of biochemical recurrence for patients with intermediate-risk prostate cancer

Fig. 5

To eliminate the effects of surgical artifacts on clinical outcomes, 63 patients with positive surgical margins for RP and their 63 matched pairs for SEED-BT were excluded from the analyses. Kaplan–Meier estimates of the biochemical recurrence-free rate were calculated using the Phoenix definition (PSA nadir plus 2 ng/mL) for SEED-BT and the surgical definition (PSA cut-off value of 0.2 ng/mL) for RP (A). Kaplan–Meier estimates of the biochemical recurrence-free rate using the surgical definition (PSA cut-off value of 0.2 ng/mL) for both SEED-BT and RP (B). Salvage hormonal therapy-free survival rate (C) and metastasis-free survival rate (D) for SEED-BT and RP. Abbreviations: CI, confidence interval; RP, radical prostatectomy; SEED-BT, seed brachytherapy
