Abstract
Results are presented of Epstein‐Barr virus‐specific serologic tests for seven Alaskan Native patients with nasopharyngeal carcinoma (NPC) from whom serum had been collected 2–10 years before diagnosis and up to 6 years after diagnosis. The pre‐illness antibody spectra and titers of the NPC patients did not differ from those of controls. However, broadened antibody spectra and elevated titers were associated with the emergence of NPC disease, which in one case was present as early as 22 months before actual diagnosis. Increasing or continuously high antibody titers were associated with progression of the disease and death, whereas patients who maintained relatively low, stable antibody titers after treatment have remained well.

## Abstract ## Background. IgA antibody titers to the Epstein‐Barr virus (EBV) viral capsid antigen (EBV IgA‐VCA) and to the EBV early antigen (EBV IgA‐EA) are used to screen for nasopharyngeal carcinoma (NPC). This study evaluates the sensitivity and specificity of EBV IgA‐VCA and EBV IgA‐EA tite
