The investigators analyzed clinical outcome in DLBCL patients according to age group to define the impact of EBV status on the clinical outcome.
Epstein-Barr virus (EBV) positive diffuse large B-cell lymphoma (DLBCL) has been recognized as a new provisional entity in the 2008 World Health Organization (WHO) classification of tumors of hematopoietic and lymphoid tissue. This lymphoma is defined as EBV+ clonal B-cell proliferation in immunocompetent adults older than 50 years. To denote patient age in definition of this disease, age cutoff was defined as older than 50 years. However, this cutoff is clearly arbitrary without any scientific background. the knowledge on EBV+DLBCL in young adult is very scanty. This EBV+DLBCL in young adult can be the same disease entity or it can be a distinct disease form EBV+DLBCL of elderly.
