A Novel Nomogram and Risk Classification System Predicting the Cancer-Specific Survival of Muscle-Invasive Bladder Cancer Patients after Partial Cystectomy

Figure 1

Nomogram predicting 1-, 3-, and 5-year bladder cancer-specific survival probabilities for muscle-invasive bladder cancer patients undergoing partial cystectomy. The variables include age, histology, T stage, N stage, M stage, regional nodes examined, and tumour size. Its use is to locate patient values at each axis. Draw a vertical line to the “Point” axis to determine how many points are attributed for each variable value. Sum the points for all variables. Locate the sum on the “Total Points” line. Draw a vertical line towards the 1 Yrs.Surv. Prob, 3Yrs.Surv. Prob., and 5Yrs.Surv. Prob, and Prob. axes to determine the 1-, 3-, and 5-year survival probabilities.
