摘要 目的探讨用PCR方法从鼻咽癌外周血中检测EB病毒DNA的意义,以及与鼻咽癌组织凋亡之间的关系。方法分别收集58例健康人外周血和50例鼻咽癌患者的外周血及其相应的肿瘤组织活检标本,用PCR方法分别检测血浆和单个核细胞中的EB病毒DNA,用TUNEL方法检测鼻咽癌细胞的凋亡情况。结果鼻咽癌患者外周血单个核细胞和血浆中的EB病毒阳性率均明显高于健康对照组。鼻咽癌患者外周血单个核细胞EB病毒阳性者的癌细胞平均凋亡指数明显高于阴性者,提示外周血单个核细胞中的EB病毒DNA与肿瘤细胞的凋亡有密切的联系。结论鼻咽癌患者外周血EB病毒DNA可能为来源于局部肿瘤细胞的分子标记物,本研究为其进一步的的临床应用提供了理论基础。
