Association of ABO Blood Types and Clinicopathological Features of Prostate Cancer

Purpose. To investigate the association between ABO blood types and clinicopathological characteristics in patients with prostate cancer (PC). Methods. A total of 237 pathologically diagnosed PC patients were enrolled. All patients were classified as low–middle or high-risk group. The correlation of ABO blood types with high-risk PC was determined by univariate and multivariate regression analysis. Results. Data indicated 144 (85.7%) patients were stratified as high risk in the non-O group, while 50 (72.5%) patients in the O group (p=0.025). However, there was no significant difference regarding PSA, Gleason score, stage, or metastasis between O and non-O group (p>0.05). Univariate logistic regression analyses revealed PSA, Gleason score, and blood type non-O were all correlated with high-risk PC (OR = 1.139, p<0.001; OR = 9.465, p
