1. Study on improving the diagnostic accuracy of treatment-naive nasopharyngeal carcinoma. / 2. Study on diagnostic accuracy of EBV-DNA on recurrent nasopharyngeal carcinoma. / 3. Studies on EBV-DNA as a screening tool for nasopharyngeal carcinoma. Part 1. To define the detection rate of NPC and the false-positive rate of IgA-VCA in an IgA-VCA-based screening problem, and to define the specificity of IgA-EA in IgA-VCA-positive screenees. Part 2. To define the specificity of EBV-DNA in IgA-VCA-positive screenees. Part 3. To define the sensitivity of IgA-EA, and EBV-DNA in IgA-positive NPC patients. / 4. Studies on pre-therapy prognostication of nasopharyngeal carcinoma Study Part 1. Objective. To assess the role of EBV-DNA in pre-therapy prognostication of early-stage NPC. / Background. The specific association between nasopharyngeal carcinoma (NPC) and the Epstein-Barr virus (EBV) had been exploited to develop a spectrum of EBV-antibodies-based blood markers. Among these markers, the Immunoglobulin A antibody against the viral capsid antigen (IgA-VCA) of the EBV has been the most popularly employed marker to assist diagnosis of NPC. There is however a relative paucity of data on the application of blood markers for screening, for detection of relapse, and for prognostification of patient cohorts managed in present-day therapy oncology protocols. Peripheral blood EBV-DNA, measured by quantitative polymerase chain reaction assay, is a newly-developed marker, and represents a prototype model of a nuclei acid-based, as opposed to antibody-based, EBV tumor marker for NPC. The present thesis describes the translation of this basic scientific advance into clinical applications, through several prospective and retrospective studies that address the diagnosis of treatment-naive NPC, the detection of recurrent NPC, the screening of individuals at risk of NPC, the pre-therapy prognostication for NPC to guide for choice of therapy. The role of integration of conventional markers and EBV-DNA in clinical applications was also examined. / Study Part 2. Objectives. To assess whether incorporation of EBV-DNA data to TNM staging improves prognostic discrimination of patients subsets within individual cancer stage, to assess if EBV-DNA is an independent prognostic factor for survival after ontological therapy.
