VALIDATION OF THE KATTAN PREOPERATIVE NOMOGRAM FOR PROSTATE CANCER RECURRENCE USING A COMMUNITY BASED COHORT: RESULTS FROM CANCER OF THE PROSTATE STRATEGIC UROLOGICAL RESEARCH ENDEAVOR (CAPSURE)

Abstract

We noted the reasonable performance of the Kattan nomogram for predicting cancer outcomes after radical prostatectomy using a community based population. Although concordance is lower than in previous validation studies and the nomogram overestimates recurrence-free survival in patients at lower risk, the model is fairly robust and it provides important information when counseling patients regarding treatment options in the community setting. Further refinements in pretreatment estimation of disease-free survival and ultimately overall survival are needed.
