Purpose: The purpose of this study was to evaluate the correlation of ABO blood types and clinicopathological characteristics of patients with ureteral transitional cell carcinoma. Materials and Methods: In our study, an entire cohort of 239 patients who were pathological diagnosed as ureteral transitional cell carcinoma (TCC) between February 2002 and March 2010 were reviewed retrospectively. Variables including demographic features, tumor grades, tumor stages, type of surgery and number of tumors as well as ABO blood types status were evaluated. The relationship between the ABO blood group and clinicopathological variables was assessed by Chi-squared analysis. Results: The ratio of male to female was 1: 1.12. The median age at diagnosis was 68.5 years. A total of 111 neoplasms located in the right ureter. A total of 218 patients had radical nephroureterectomy (RNU). Multifocality was observed in 32 patients. The pathology was as follow: Grade 1 (seven cases), Grade 2 (110 cases) and Grade 3 (122 cases); Ta and T1 (83 cases), T2-T4 (156 cases). The distribution of ABO blood types was A, B, O and AB in 70 (29.3%), 76 (31.8%), 66 (27.6%) and 27 (11.3%), respectively. There were no significant differences in the clinicopathological variables among individuals with different ABO blood types. In a subgroup analysis, B and O group showed a worse tumor stage compared with A and AB groups (P = 0.01). Conclusion: B and O blood types are at higher risk of muscle invasive ureteral TCC as compared with A and AB blood types. We suggest ABO blood types to be taken into consideration when urologists select therapeutic schemes for individuals with ureteral TCC.
