简要总结
The purpose of this study is to determine if we can prevent Epstein Barr Virus lymphomas by the monthly administration of an (antibody) protein against B lymphocytes called Rituximab. Although this medicine has been approved by the Food and Drug Administration to treat patients with other types of lymphomas, and has been used to treat a small number of patients with EBV lymphomas and other types of B-cell leukemias, it has not been approved to try and prevent EBV-lymphomas. Use of Rituximab to try to prevent EBV-lymphomas is therefore experimental.

研究组 & 干预措施
Rituximab
Patients following a T cell depleted HLA-mis-matched related or unrelated hematopoietic stem cell transplant (HSCT) will be treated with monthly Rituximab.
干预措施: Rituximab (Drug)
结局指标
主要结局
Safety of Rituximab Prophylaxis
时间窗: 3 months post transplant
The following stopping rules will be employed to determine that the risks of graft failure, severe GvHD, treatment-related mortality, infection, and EBV-LPD in study patients are not increased over expected. In addition, patients will be removed from study if they develop irreversible non-hematologic Grade III toxicity or any Grade IV toxicity felt to be related or possibly related to study drug.
