Acute graft versus host disease(AGVHD) is a major cuuse cf mortality in mismatched(MM) bone marrow transplant(BMT). T-eoil depletion(TCD) reduces AGVHD but increases relapse & rejection. 61 patients treated with MM BMT using total body irradiat'cn, cyclophosphamide, thiotepa, antithymocyte globulin with cyclospc., methotrexate and steroids for AGVHD prophylaxis were random. I for partial TCD. Stratification is reviewed below.

In conclusion, partial TCD reduced the risk of severe AGVHD; the effect on survival requires longer follow-up.
