Abstract

Objectives

Epstein-Barr virus(EBV) is associated with development of various types of lymphoma, especially NK/T cell lymphoma. Recently, its subtypes and LMP-1, major oncoprotein of EBV, have been studied. We investigated the frequency of EBV, its subtypes, and LMP-1 status on the cases diagnosed at Ewha university hospital between 1993 and 2002.

Material and Methods

Sixteen cases of NK/T cell lymphomas were studied. In situ hybridization for EBER-1 mRNA and PCR for EBV subtypes and 30 base pair deletion of LMP-1 were done.

Results

All cases showed EBV positivity by EBER in situ hybridization. All cases contained Type A viruses and 10 cases(62.5%) revealed LMP-1 30bp deletion.

Conclusion

EBV act as a causative role in the development of NK/T cell lymphoma. The exact role of LMP-1 30bp deletion variant in the lymphomatogenesis should be studied with larger number of cases.
