Unveiling the Impact of Epstein-Barr Virus on the Risk of Prostate Cancer: A Mendelian Randomization Study.

Given the consistent detection of Epstein-Barr virus (EBV) in prostate tissues and the clinical evidence suggesting its involvement in prostate cancer (PCa), the potential association between EBV infection and PCa warrants further investigation. This study aimed to assess the causal relationship between EBV infection and PCa using Mendelian randomization (MR). We utilized data from a publicly available genome-wide association study (GWAS) on PCa, alongside data on five serum anti-EBV virus-related antibodies. Our findings indicate a potential causal link between serum EBV EA-D antibody levels and an increased risk of PCa. These results highlight the need for additional research to elucidate the mechanisms by which EBV may contribute to the progression of PCa, potentially offering new insights into its pathogenesis and therapeutic targets.
