    Abstract:
    OBJECTIVE: Nasopharyngeal Carcinoma (NPC) is an endemic head and neck malignancy in Asia Pacific regions that is associated with chronic infection by Epstein-Barr virus (EBV). EBV miR-BART-7 is a microRNA (miRNA) encoded by EBV that regulates malignant behavior of NPC. However, the role and function of miR-BART7 are not clear, particularly the relation of circulating levels and patient's clinical presentation. METHODS: Circulating miR-BART-7 levels were measured by using qRT-PCR and were correlated with clinical and pathological data. RESULT: Of 52 NPC patients included in this study, 85% were diagnosed in the late stages (Stage III-IV). 73% of tumors were non-keratinizing undifferentiated NPC, 92% of tumors were WHO class III histology and all cases were EBV-IgA positive. Over-expression of miR-BART7-3p was correlated with positive regional lymph nodes in newly diagnosed (4.61 fold changes, p <0.05). CONCLUSION: Over-expression of circulating EBV miR-BART7 correlated with positive regional lymph nodes reflecting the diagnostic and prognostic values of circulating miR-BART7 for patients with NPC.
