Overview
This study aims to evaluate the clinical efficacy of cyclophosphamide in patients receiving a bone marrow graft from a matched unrelated donor in overall survival, progression free survival and cumulative incidence of acute and chronic GvHD. Thirty patients will receive cyclophosphamide while twenty patients will receive antihuman T-lymphocyte immune globulin (ATG).

- Hematological malignancy
Exclusion Criteria:
- Acute leukemias not in complete response (that is > 5% blast in the bone marrow)
- Chemorefractory lymphoproliferative disease
- Active uncontrolled infection
- HCT-CI > 3

- Previous allogeneic bone marrow transplantation
- Contraindication to cyclophosphamide or ATG
