Postoperative nomogram for invasive bladder cancer: does it really work? A multicenter cohort study.

Objectives: Nomograms are statistical models designed to maximize predictive accuracy. We have tested the statistical correlation between the predictions of International Bladder Cancer Nomogram Consortium and the clinical outcomes in a multicenter Italian cohort of patients treated with radical cystectomy (RC) and pelvic lymph-nodes dissection. Methods and materials: Two hundred four patients who underwent RC were selected for multiple variable and then enrolled in the study. Patients were tested by the "online tool" based on the nomogram, then stratified and risk grouped for 5-year predicted disease-free survival (pDFS): low risk (67%-100%), intermediate risk (34%-66%), and high risk grou…
