Cellular Immunotherapy for Viral Induced Cancer / EBV Positive Lymphomas

To investigate the efficacy of autologous Epstein-barr virus (EBV)-specific T cells for the treatment of EBV positive Diffuse Large B Cell Lymphoma (DLBCL), Hodgkin Lymphoma (HL) and Post-transplant Lymphoproliferative Disease (PTLD) after failing first line treatment.
