Prevalence of Epstein–Barr virus in North-East Indian breast cancer patients' blood

BACKGROUND: Breast cancer (BC) has been the most frequently diagnosed cancer among women and it has multiple risk factors. Epstein–Barr virus (EBV) has been shown to be associated with BC as one of the risk factors. Our aim was to detect EBV DNA in blood samples of BC patients of North-East India. M...

Description
Summary:	BACKGROUND: Breast cancer (BC) has been the most frequently diagnosed cancer among women and it has multiple risk factors. Epstein–Barr virus (EBV) has been shown to be associated with BC as one of the risk factors. Our aim was to detect EBV DNA in blood samples of BC patients of North-East India. MATERIALS AND METHODS: A total of 53 eligible BC patients' samples were analyzed by Nested polymerase chain reaction for EBV Antigen-1 (EBNA1) gene. All statistical analysis was carried out using the software of statistical package for social sciences (SPSS) version 21. RESULTS: 20.8% (11 of 53) BC patients' blood samples have EBNA1 gene DNA. The median age of BC patients was 42 and 43 years for EBV-positive and EBV-negative groups. 96.22% EBV-positive BC patients were diagnosed with high-grade malignancy. 54.54% of EBV-positive BC patients were diagnosed with T3 and T4 stage cancer. EBV-positive patients have not shown statistically significant association with ER positive (P-0.877, odds ratio [OR]: 1.111), PR positive (P-0.256, OR-2.16), Her-2/neu positive (P-0.93, OR-1.017), Ki-67 positive (P-0.487, OR: 1.8), and AR positive (p-1.000, OR-0.836). CONCLUSION: We conclude from our study that EBNA1 gene was found in the blood samples of subset of BC patients of North-East India. Further studies with BC tissue and adjacent normal tissue samples of BC patients will be required to provide evidence about EBV's role with BC of North-East India.
