Nasopharyngeal carcinoma (NPC) is common in southern China and Southeast Asia. Epstein-Barr virus (EBV) infection is an important etiology for NPC, and EBV genome can be detected in almost all tumor tissues of NPC in this region. Plasma EBV DNA, when quantitatively analyzed using real-time polymerase chain reaction (PCR), has been developed as a biomarker for NPC. In this review, the different clinical applications of plasma EBV DNA in the management of NPC, including screening, monitoring, and prognostication, are discussed. In addition, the biological issues of circulating EBV DNA, including the molecular nature and clearance kinetics, are also explored.
鼻咽癌(NPC)在中国南方和东南亚地区较为常见。爱泼斯坦-巴尔病毒(EBV)感染是NPC的重要病因,该地区几乎所有NPC肿瘤组织中都能检测到EBV基因组。血浆EBV DNA通过实时聚合酶链反应(PCR)进行定量分析,已被开发为NPC的一种生物标志物。在本综述中,讨论了血浆EBV DNA在NPC管理中的不同临床应用,包括筛查、监测和预后评估。此外,还探讨了循环EBV DNA的生物学问题,包括分子性质和清除动力学。
