    Abstract:
    INTRODUCTION: To describe factors associated with peri-operative blood transfusion (PBT) at radical cystectomy (RC) for patients with bladder cancer and evaluate its association on both early and late outcomes. METHODS: Electronic records of treatment and surgical pathology reports were linked to the population-based Ontario Cancer Registry to identify all patients who underwent RC between 2000 and 2008. Modified Poisson regression model was used to determine the factors associated with PBT. A Cox-proportional hazards regression model was used to explore the association between PBT and overall (OS) and cancer-specific (CSS) survival. RESULTS: Among 2593 patients identified, 62% received an allogeneic red blood cell transfusion. The frequency of PBT decreased over the study period (from 68 to 54%, p < 0.001). Factors associated with PBT included age, sex, greater co-morbidity, stage, and surgeon volume. PBT was associated with inferior outcomes, including median length of stay (11 vs. 9 days, p < 0.001), 90-day re-admission rate (38 vs. 29%, p < 0.001), and mortality (11 vs. 4%, p < 0.001). OS and CSS at 5 years were lower among patients with PBT on multivariate analysis (OS HR 1.33, 95% CI 1.20-1.48; CSS HR 1.39, 95% CI 1.23-1.56). CONCLUSIONS: Although rates are decreasing, these data suggest a very high utilization rate of PBT at time of RC in routine clinical practice. PBT is associated with substantially worse early outcomes and long-term survival. This association persists despite adjustment for disease-, patient-, and provider-related factors, suggesting that PBT is an important indicator of surgical care of RC.
