Radical Cystectomy Survival Calculator
We developed a nomogram assessing predictors for 3- and 5-year overall and cancer-specific survival derived from 5,325 patients aged 66 years of age and older derived from the Surveillance, Epidemiology, and End Results (SEER) Medicare-linked cancer registry in the United States. The nomogram was validated in the Texas Cancer Registry Medicare-linked database which predicted 3- and 5-year overall and cancer-specific survival rates with a Concordance-Indices of 0.65 and 0.66, respectively. We did not observe a significant association between radical cystectomy and non-cancer survival (HR 1.00; 95% CI, 0.81 to 1.23, p=0.999) thus limiting the effect of unmeasured confounding by indication or selection bias in the development of the nomogram. This nomogram has been converted into the Radical Cystectomy Survival Calculator© (RCSC), an on-line tool, to provide a benefit-risk assessment for patients considering radical cystectomy.
