Measure
Total Body Irradiation (TBI)/Cyclophosphamide (Cy)
Patients with lymphoid malignancies will receive Total Body Irradiation (TBI)/Cyclophosphamide (Cy). Bone marrow grafts will be used. HLA-identical sibling donors will be considered first followed by histocompatible relatives or unrelated donors. Permissive DPB1 mismatched grafts will be included. Unrelated grafts will be obtained through NMDP or other registries. Participants receive 8 doses TBI. Cyclophosphamide, IV. Rabbit ATG, IV. Males with lymphoid lineage leukemia will receive an additional testicular boost concurrent with TBI. Patients who receive a bone marrow product from MSD will not receive rATG. G-CSF: Use of GCSF is not recommended except after day +21 when a single dose not exceeding 2.5mcg/kg may be given after rounding off if APC is \>500 cells/mm3, and ANC is\<500 cells/mm3 to mobilize cells. Mesna: Mesna will be given IV approximately 15 minutes prior to each dose of cyclophosphamide and approximately 3, 6, 9, and 12 hours after each dose of cyclophosphamide. GVHD prophylaxis: Cyclosporine, IV. Methotrexate, IV. Ruxolitinib, Oral or NG.
