Abstract

OBJECTIVES: To evaluate the association of ABO blood type with clinicopathologic outcomes and mortality among patients with urothelial carcinoma of the bladder treated with radical cystectomy (RC).

PATIENTS AND METHODS: We identified 2,086 consecutive patients who underwent RC between 1980 and 2008. Postoperative recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan Meier method and compared with the log-rank test. Cox proportional hazards regression models were used to evaluate the association of ABO blood type with outcomes.

RESULTS: A total of 913 (44%), 881 (42%), 216 (10%), and 76 (4%) patients had blood type O, A, B, and AB, respectively. Median postoperative follow-up among survivors was 11.0 years (interquartile range: 7.7-15.9y). Overall, 1,561 patients died, with 770 deaths attributable to bladder cancer. Non-O blood type was associated with significantly worse 5-year RFS (65% vs. 69%; P = 0.04) and/or CSS (64% vs. 70%; P = 0.02). In particular, among patients with≤pT2N0 disease, the 5-year RFS for those with non-O vs. O blood type was 75% vs. 82%, respectively (P = 0.002), whereas the 5-year CSS was 77% vs. 85%, respectively (P = 0.001). Moreover, on multivariable analysis, blood type A remained independently associated with an increased risk of cancer-specific mortality (hazard ratio = 1.22; P = 0.01).

CONCLUSIONS: Non-O blood type, particularly blood type A, is associated with a significantly increased risk of death from bladder cancer among patients undergoing RC. If validated, the utility of a multimodal therapy approach, including perioperative chemotherapy, or more frequent postoperative surveillance in this cohort warrants further study.
