<qa>  What type of lymph gland cancer has come back after treatment?Subjects have a type of lymph gland cancer called Hodgkin or non-Hodgkin Lymphoma, which has come back or not gone away after treatment, including the best treatment we know for relapsed Lymphoma. We are asking subjects to volunteer to be in a research study using Epstein Barr virus EBV specific cytotoxic T lymphocytes, a new experimental therapy. This therapy has never been used in patients with Hodgkin disease or this type of non-Hodgkin Lymphoma but it has been used successfully in children with other types of blood cancer caused by EBV after bone marrow transplantation.
