Background • Prevalence prostate cancer in Europe: ~382,000 • Risk assessment tools • Risk groups • Nomograms • Clinical Prediction Rule
CAPRA-score 0-2 points Low risk 3-5 points Intermediate risk ≥6 points High risk
Study aim To determine the prognostic value of the CAPRA-score in patients with localized prostate cancer after radical prostatectomy - 3 and 5 year survival rates across 3 strata of risk
Statistical methods- Calibration • Original derivation study used as a predictive model against which the validation studies are compared • Results are presented as a ratio measurement across three strata of risk RR >1 = over prediction by rule RR<1 = under prediction by rule RR=1 = correct prediction by rule
Quality assessment • To assess the methodological quality of the validation studies • 2 independent raters • McGinn quality checklist • internal validity • external validity

Discussion • This is the first study to review the validity of the CAPRA-score systematically • Heterogeneity between studies needs to be considered • Future studies • Larger studies • Different treatments
Conclusion • The CAPRAscore correctly predicts recurrence free survival 3 years after RP in all three risk groups • The CAPRA-score significantly under-predicts recurrence free survival 5 years after RP
