“…The ability of seromarker titers to predict the outcome of NPC patients was also examined. In line with previous studies ( 36 , 37 ), our results demonstrate that antibody titers of known seromarkers, VCA-IgA and EBNA1-IgA, could not be used to predict the survival of NPC patients accurately. However, NPC patients with elevated levels of BLLF3-IgA and BDLF1-IgA titers had significantly worse DFS, suggesting these two seromarkers may be potential prognostic indicators of NPC ( Fig.…”
