Brief Summary
In an effort to identify genetic factors linked to the development of nasopharyngeal cancer (NPC), the researchers identified and sampled 2,394 individuals from Taiwanese families in which two or more relatives had been diagnosed with NPC. Serum from these individuals was tested for three anti-Epstein-Barr virus (EPV) antibodies associated with elevated risk of NPC. Results indicate that apparently healthy individuals from high-risk families have a nearly threefold elevation in their EBV antibody prevalence compared with the general population. However, the clinical implications of this finding are not yet understood. To clarify the implications, the 2,394 unaffected individuals from the multiplex family study will be invited to participate in the current study. Approximately 1,600 individuals are expected to participate. Participants will have an ear, nose, and throat examination to determine if they have occult or symptomatic NPC. Their levels of EBV antibody at the time of initial recruitment will be correlated with NPC detection in the period between initial recruitment and the present study. Participants will also be asked to complete a brief risk factor questionnaire and to donate blood, saliva, a nasopharyngeal swab, nasopharyngeal tissue, and urine for future studies. Currently, no accepted clinical management protocol exists for screening unaffected members from families at high risk of NPC development. Results from this study have the potential to significantly impact the clinical management and follow-up of individuals with a family history of NPC.
