[Real-time quantitative PCR assay of Epstein-Barr virus in whole blood cells of nasopharyngeal carcinoma patients].
EBV is detected in more and more tumors, and is relative to carcinogenesis. We studied the copies of EBV DNA in whole blood of NPC patients and healthy controls by real-time quantitative PCR. In the 73 NPC patients and 83 controls, the positive rate of EBV in blood of NPC is 46.6%, while 13.3% in control. The mean copy number is 3.9 x 10(4) copys/microgram DNA in controls, which is much higher than NPC patients (which is 1.7 x 10(5) copies/microgram DNA). EBV infection is relative with NPC, while the lytic form of EBV maybe more important than its latent form. These results suggest that whole blood EBV DNA may be a valuable tool for molecular diagnosis of NPC.
