Kaplan-Meier curve of BCR-free survival following radical prostatectomy in patients with at least one high-risk feature, according to IDC-P and treatment status. Patients treated by RPonly and who had IDC-P were the outlying group with poor outcome. Log-rank testing P = 0.023. When comparing IDC-P patients only (red and blue curves), mean survival of RP + ART patients was 112 months (95% CI: 85–138, median not yet reach), and median survival of RPonly patients was 69 months (95% CI: 28–111), with log-rank testing P = 0.158. Abbreviations: IDC-P: intraductal carcinoma of prostate. RP: radical prostatectomy. ART: adjuvant radiotherapy. HRF: High-risk features (GG4–5, seminal vesicle invasion, positive margins, extraprostatic extension)
