It is much more frequent in Asian and Latin American countries than other part of the world. It typically affects nasal cavity. In China, one of its endemically places, ENKTCL accounts for 74%-96% of nasal NHL. Patients with ENKTCL usually show a highly aggressive clinical course, and its etiology is unclear. However, it is already proved that ENKTCL is associated with Epstein-Barr virus （EBV） infection, regardless patients＇, ethnicity and areas. Some studies show that the risk will increase among several occupations, such as farmer, who are frequently exposure to pesticides and chemical solvent and risk can be cut down if taking some protective measures.展开更多
