The management of active surveillance in prostate cancer: Validation of the Canary Prostate Active Surveillance Study risk calculator with the Spanish Urological Association Registry

Abstract

The follow up of patients on active surveillance requires to repeat prostate biopsies. Predictive models that identify patients at low risk of progression or reclassification are essential to reduce the number of unnecessary biopsies. The aim of this study is to validate the Prostate Active Surveillance Study risk calculator (PASS-RC) in the multicentric Spanish Urological Association Registry of patients on active surveillance (AS), from common clinical practice. Results: We find significant differences in age, PSA and clinical stage between our validation cohort and the PASS-RC generation cohort (p
