The goal of this clinical research study is to learn if cyclophosphamide given after busulfan and fludarabine can help to prevent graft versus host disease (GVHD - a condition in which transplanted tissue attacks the body into which it is transplanted) in patients receiving a stem cell transplant. The safety of this drug combination will also be studied.

Primary Outcome Measures:
  • Incidence of Grade III to IV Acute Graft Versus Host Disease (GVHD) [ Time Frame: 100 days post transplant ] [ Designated as safety issue: Yes ]
    GVHD defined as grade 3 or 4 GVHD within first 100 days post transplant.

  • Non-Relapse Mortality [ Time Frame: 25 days post transplant ] [ Designated as safety issue: No ]

    Relapse defined according to disease specific criteria recorded by the day of detection.

    Progression free survival defined as the interval between day of transplant and day of death or disease progression.

    Overall Survival defined as the interval between day of transplant and day of death.

Secondary Outcome Measures:
  • Incidence of Engraftment [ Time Frame: 28 days post transplant ] [ Designated as safety issue: No ]
    Engraftment defined as the evidence of donor derived cells (more than 5%) by bone marrow chimerism studies in the presence of neutrophil recovery by day 28 post stem cell (SC) infusion.
