Summary

Epstein-Barr virus (EBV) is a double-stranded DNA human gamma herpes virus that establishes a persistent infection in over 90% of individuals. Most infections are self-limiting, but some cases are associated with the development of malignancies of lymphoid or epithelial origin. EBV-associated gastric carcinomas (EBVaGC) make up about 9% of all stomach cancers.

The constant presence of the viral genome in EBVaGC suggests the applicability of novel EBV-targeted therapies.

The antiviral nucleoside drug, (val)ganciclovir (GCV), is effective only in the context of the viral lytic cycle in the presence of EBV-encoded thymidine kinase (TK)/ protein kinase (PK) expression. JM Lee et al. reported that gemcitabine was lytic inducer via activation of the ATM/p53 genotoxic stress pathway in EBVaGC and confirmed the efficacy of gemcitabine-GCV combination treatment.

So we planned this proof of concept trial to apply the antiviral agent in EBVaGC.
