title: Copy number analysis in EBV-positive nodal peripheral T cell lymphoma, unspecified.
abstract: Copy number alteration was investigated in three cases of EBV + nodal peripheral T cell lymphoma of cytotoxic phenotype using Agilent array comparative genomic hybridization platform. While no recurrent abnormality among three cases was identified, genomic abnormalities involving 9p23.3, 16p13.3, and 7q34 were overlapped with changes reported in other type of NK or T cell lymphomas previously. Chromosomal region 9p23.3 contains CDKN2A and CDKN2B which are frequently mutated or deleted in various types of cancer and may be a target to find genes associated with the pathogenesis of EBV-positive nodal peripheral T cell lymphoma.
