摘要 鼻咽癌是我国常见的恶性肿瘤,EB病毒(Epstein-Barr virus,EBV)感染是鼻咽癌发生的重要因素.鼻咽上皮细胞的EBV感染是癌变过程中侵袭前的变化,几乎在100%的鼻咽癌活检组织中存在EBV的基因.目前,利用聚合酶链反应(polymerase chain reaction,PCR)技术检测鼻咽癌患者血浆中EBV-DNA已应用于临床,检出率达96%,而传统的原位杂交方法在鼻咽癌组织中EBV编码的小RNA(EBV-encoded small RNA,EBER)仍有显著表达.本文在鼻咽癌患者外周血及鼻咽部活检组织石蜡标本中联合检测鼻咽癌患者外周血中EBV-DNA载量与鼻咽癌组织中EBER表达的差异,探讨EBV感染在鼻咽癌变过程中的变化,并对同一患者的标本进行两种方法的研究.
