 Some patients with Lymphoma, TNK-lymphoproliferative disease, or CAEBV show signs of a virus called Epstein Barr virus EBV that causes mononucleosis or glandular fever mono or the kissing disease before or at the time of their diagnosis. EBV is found in cancer cells of up to half the patients with HD and NHL, suggesting that it may play a role in causing Lymphoma. The cancer cells in lymphoma and some immune system cells in CAEBV infected by EBV are able to hide from the bodys immune system and escape destruction. We want to see if special white blood cells MABEL CTLs that have been trained to kill EBV infected cells can survive in your blood and affect the tumor.
