From: The diagnostic and prognostic values of plasma Epstein-Barr virus DNA for residual cervical lymphadenopathy in nasopharyngeal carcinoma patients: a retrospective study

Examination Sensitivity (%) Specificity (%) PPV (%) NPV (%)
FNAC 84.2 100.0 100.0 40.0
EBV DNA detection 52.9 100.0 100.0 30.4
FNAC + EBV DNA detection 89.5 100.0 100.0 40.0
  1. PPV positive predictive value, NPV negative predictive value, NPC nasopharyngeal carcinoma, FNAC fine needle aspiration cytology, EBV Epstein-Barr virus
