Association of ABO Blood Types and Clinicopathological Features of Prostate Cancer

الملخص EN

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<0.001; OR = 2.280, p=0.018, resp.).

In the stepwise multivariate regression analysis, the association between blood type non-O and high-risk PC remained significant (OR = 33.066, 95% CI 2.391–457.323, and p=0.009) after adjusting for confounding factors as well as PSA and Gleason score.

Conclusion.

The present study firstly demonstrated that non-O blood type was at higher risk of aggressive PC compared with O type, suggesting that PC patients with non-O blood type should receive more attention in clinical practice.
