POPULATION CHARACTERS IN HIGH RISK PEDIGREES OF NASOPHARYNGEAL CARCINOMA (NPC)
Abstract
Objective: To investigate population characters in high risk pedigrees of NPC in Guangdong area akld to explore the effect each other between tumor genetic susceptibility and infection of EB virus on pathogenic mechanism.
Methods: Pedigree investigation, examination of DNA fingerprint, multi-antibodies of EB virus and nasopharyngeal cavity were done for all of the members in each high risk pedigree.
Results: High positive rate of EBV VCA/IgA (23.22%), high percentage of high risk population of NPC (6.53-10.40%), high detected rate of malignant tumor (9552.59/10s), and high detected rate of NPC (8464.32/10 s) were discovered and NPC was most common in first degree relative of a pedigree.
Conclusion: Tumor genetic susceptibility, infection of EB virus might play a role in coordination of reinforced effect on occurrence of NPC.
