- Incidence of Chronic GVHD [ Time Frame: 2 years ]Analyzed using cumulative incidence estimates, treating death or rejection as competing risk events.
- Number of Days to Neutrophil Recovery to >500/uL [ Time Frame: 100 days post-transplant ]First of 3 consecutive days of neutrophils >500/uL
- Overall Survival [ Time Frame: From the time of enrollment until death from any cause up to one year ]Number of patients alive at one year

Experimental: Treatment (conditioning regimen, transplant, GVHD prophylaxis)
Patients receive a conditioning regimen comprising cyclophosphamide IV on days -5 to -2 and anti-thymocyte globulin IV over 4-10 hours on days -4 to -2. Patients undergo allogeneic bone marrow transplantation on day 0. Patients then receive GVHD prophylaxis comprising methotrexate IV on days 1, 3, 6, and 11 and cyclosporine IV over 1 hour or PO twice daily on days -1 to 50, followed by a taper until 6 months after grafting.

I. Minimize the incidence of chronic GVHD by restricting the transplanted marrow dose to 2.0-2.5 x 10^8 nucleated cells/kg.
I. Engraftment and overall survival.
CONDITIONING REGIMEN: Patients receive cyclophosphamide intravenously (IV) on days -5 to -2 and anti-thymocyte globulin IV over 4-10 hours on days -4 to -2.
TRANSPLANTATION: Patients undergo allogeneic bone marrow transplantation on day 0.
GVHD PROPHYLAXIS: Patients receive methotrexate IV on days 1, 3, 6, and 11 and cyclosporine IV over 1 hour or orally (PO) twice daily on days -1 to 50, followed by a taper until 6 months after grafting.
After completion of study treatment, patients are followed up at on day 180, 1 year, 1.5 years, 2 years, 3 years, and yearly thereafter.
