 The cells will then be thawed and injected into the patients vein over 10 minutes, after pretreatment with Tylenol and Benadryl. Tylenol and Benadryl are given to prevent a possible allergic reaction to the T cell administration. Initially, two doses of T cells will be given two weeks apart. If after the second infusion there is a reduction in the size of the patients lymphoma on CT or MRI scan as assessed by a radiologist, the patient can receive up to six additional doses of the T cells. All of the treatments will be given at Texas Childrens Hospital or the Methodist Hospital.
