ABSTRACT: Background
Systemic inflammatory response (SIR) is important in the relationship between the tumour, the host, and outcome in cancer patients. However, limited data exist regarding the prognostic significance of SIR in bladder cancer. We investigate the utility of pretreatment SIR in patients with urothelial carcinoma undergoing radical cystectomy.Methods
The study cohort consisted of 419 patients with a median follow-up of 37.7 months. The SIRs used for each described prognostic nomogram are consistent with previously published data: C-reactive protein, albumin, white cell count, neutrophil count, lymphocyte count, and platelet count. Primary end point was disease-specific survival (DSS) and overall survival (OS) after surgery. Cox regression models were used to determine the time to disease-specific and overall mortality. Multivariate regression coefficients of the predictors were used to develop nomograms for predicting 5-year DSS and OS probability.Results
Multivariate Cox regression analyses revealed that albumin, lymphocyte count, and platelet count were significantly associated with a significantly increased risk for death from bladder cancer. The nomograms including each index were developed to predict the probability of 5-year DSS and OS after radical cystectomy. The C statistics were 77.8% and 77.3%, respectively, and exceeded the 2002 AJCC (72.0% and 70.3%, respectively). In the decision curve analyses, the nomograms including SIR demonstrated higher net benefit gains compared with the models without SIR.Conclusions
Cellular components of SIR have better prognostic values compared with acute-phase protein in patients undergoing radical cystectomy for bladder cancer.
