Abstract
|
|
|
Epstein-Barr virus (EBV) infection is associated with various lymphoproliferative diseases, including Hodgkin lymphoma, extranodal NK/T cell lymphoma, aggressive NK cell leukemia, Burkitt lymphoma and post-transplant lymphoproliferative disorder. In the recent studies, the plasma EBV-DNA levels in patients with EBV-associated lymphoproliferative disease appeared to be correlated with the therapeutic response. Aggressive NK cell leukemia (ANKL) is a fatal disease that¡¯s characterized by high fever, lymphadenopathy, hepatosplenomegaly and frequent hemophagocytosis. No serological tumor marker for this malignancy has yet been identified for monitoring the disease and predicting the outcome. We experienced a case of aggressive natural killer cell leukemia in a 48-year-old man, and we serially monitored the plasma EBV DNA load by performing real time quantitative PCR assay. Serial measurements of the plasma EBV DNA level during therapy showed a close correlation between the clinical response and the changes in the plasma EBV DNA titers.
