- Abstract
Objective: The aim of this study is to explore the value of EBV DNA monitor in high risk population of nasopharyngeal carcinoma (NPC). Method: A total of 366 cases of NPC at high risk were screened for 15 864 cases by ELISA, and 262 cases were randomly selected from low-risk groups. Fifty-eight nasopharyngeal carcinoma patients were also involved. EBV DNA was detected by PCR in 366 NPC high risk patients and followed up for 1 year. The clinical significance of EBV-DNA in screening NPC was compared. Result: The positive rate of EBV-DNA test was 12.0% in primary screening, EBV-DNA test in primary screening was 3.4% in low-risk population, and EBV-DNA in nasopharyngeal carcinoma was 91.4%, The positive rate of the three groups was statistically significant ( P <0.01); After one year follow-up, a total of 267 cases returned visit. Positive rate of group A with continuous high risk was significantly higher than group B who was high risk at the first time of visit and non high risk at returned visit ( P <0.05). Conclusion: Quantitative analysis of plasma EBV DNA in high risk population can supply serological risk assessment. It can elevate the efficiency of screening and has significant application value for NPC high risk population.
