MB based RT-qPCR increase the clinical application of cfEBV DNA for NPC in non-endemic area of China.

ABSTRACT: To compare the performance of magnetic bead (MB) and the concentrated precipitation (CP) based RT-qPCR to qualify cell free EBV DNA (cfEBV DNA) for nasopharyngeal carcinoma (NPC) in non-endemic area of China. From January 2014 to June 2024, a retrospective analysis of 2 cohort studies on cfEBV DNA in NPC patients was conducted to assess the diagnostic value, positive detection rate and clinical application. cfEBV DNA detection with CP based RT-qPCR in cohort 1 and MB based RT-qPCR method in cohort 2. The MB based RT-qPCR for the quantitative measurement of cfEBV DNA load was higher than the CP based RT-qPCR in the same plasma samples from NPC patients (P < 0.001). CP based RT-qPCR measured cfEBV DNA in 1405 NPC and 244 healthy controls in cohort 1 with 40.8% sensitivity (AUC = 0.704, 95% C
