It is the main point to focus on the elucidating of the pathogenesis of PNC as a polygenetic inheritance tumor, primarily establishing of the concept of susceptibility gene groups in NPC and the carcinogenesis model of the multi-step Domino effect involved in the molecular mechanisms of NPC dominated by susceptibility gene groups in order to lay out a substantial foundation for finding the high-risk susceptibility factors of NPC, screening the high-risk population of NPC and exploring the targetic and individual measures in diagnosis and treatment of NPC.
