Like EBV-positive Hodgkin lymphoma (HL) and nasopharyngeal carcinoma (NPC), EBV-infected cells in patients with NKTCL have been observed to express genes of latency I (EBNA1 and EBER1/2) or latency II (LMP1/2A/2B, EBNA1, and EBER1/2)5, 6. This evidence concerns the gene PDLIM7 and nasopharyngeal carcinoma.
