DETECTION OF EPSTEIN-BARR VIRUS GENOME IN PEDIATRIC PATIENTS WITH LEUKEMIA AND HODGKIN LYMPHOMA: VIRAL ETIOLOGY IN PEDIATRIC CANCERS IN TÜRKİYE
Objective: Cancer is a pervasive disease characterized by its widespread occurrence and challenging treatment process. While numerous agents, including viruses, have been identified as potential causes of cancer in both adults and children, the complete pathogenesis of cancers remains incompletely elucidated. This study aimed to examine the presence of four viral agents, namely Human T-cell Lymphotropic Virus Type 1 (HTLV-1), Epstein-Barr Virus (EBV), Kaposi's Sarcoma- Associated Herpesvirus (KSHV), and Human Parvovirus B19 (HPV B19), in blood samples obtained from pediatric patients (n=64) diagnosed with B cell acute lymphoblastic leukemia (ALL), T cell ALL, Hodgkin lymphoma, and patients with relapsed leukemia and lymphoma. Material and Methods: The whole blood samples collected from the patients during the pre-treatment and post-treatment periods underwent polymerase chain reaction (PCR) and real- time PCR to identify the presence of the viral genomes of HTLV-1, EBV, KSHV, and HPV B19. The samples that tested positive were subsequently subjected to Sanger sequencing, followed by phylogenetic analysis. Results: Among a total of 64 samples analyzed, HTLV-1, KSHV, and HPV B19 were found to be negative. However, EBV genome was detected in six samples (9.37%) from patients with ALL and Hodgkin lymphoma, comprising both pre- treatment (n=3) and post-treatment (n=3) cases. Subsequent sequencing and alignment of the positive EBV samples with other EBV sequences deposited in GenBank revealed a high degree of similarity. Conclusion: Our findings suggest that EBV may be one of the viral agents implicated in pediatric cancer cases involving leukemia and Hodgkin lymphoma. Therefore, it is recommended to consider testing for the presence of EBV genome in these patient populations within the context of Türkiye. This information contributes to a better understanding of the viral etiology underlying pediatric cancers, enabling the development of targeted diagnostic and therapeutic strategies in the future.
