Circulating pretreatment Epstein Barr Virus DNA quantification as a prognostic factor in nasopharyngeal cancer patients in a non endemic area

Background: The value of plasma Epstein Barr Virus (EBV) DNA viral load in nasopharyngeal cancer (NPC) patients before treatment correlates with tumor stage and outcome in endemic areas. The aim of our analysis is to explore the role of EBV DNA in the Italian non endemic setting where just one experience has been previously reported (Ferrari D et al, 2012). Material and methods: The medical records of all the patients with positive EBV encoded...
