Busulfan, Etoposide, and Total-Body Irradiation in Treating Patients Undergoing Donor Stem Cell or Bone Marrow Transplant for Advanced Hematologic Cancer
RATIONALE: Giving chemotherapy and total-body irradiation before a donor stem cell transplant or a donor bone marrow transplant helps stop the growth of cancer and abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving mycophenolate mofetil and cyclosporine before and after transplant may stop this from happening.
PURPOSE: This phase II trial is studying the side effects and best way to give busulfan together with etoposide and total-body irradiation and to see how well they work in treating patients who are undergoing a donor stem cell or bone marrow transplant for advanced hematologic cancer.

|Official Title:||Phase II Study of IV Busulfan Combined With 12 cGy of Fractionated Total Body Irradiation (FTBI) and Etoposide (VP-16) as a Preparative Regimen for Allogeneic Bone Marrow Transplantation for Patients With Advanced Hematological Malignancies|
- Efficacy as determined by disease free survival [ Time Frame: 5 years post transplant ]
- Disease-free survival at 2 years and 5 years [ Time Frame: 5 years post transplant ]
- Prognostic factors for relapse, disease-free survival, and overall survival evaluated by cytogenetics, WBC at presentation, targeted busulfan dose, and number of courses of induction therapy to achieve remission [ Time Frame: 5 years post transplant ]
- Early and late toxicities [ Time Frame: 30 days, 31-100 days, 101 to 365 days and yearly through 5 years post transplant ]
|Study Start Date:||January 2000|

|Estimated Primary Completion Date:||January 2018 (Final data collection date for primary outcome measure)|
Experimental: Busulfan, FTBI and VP16
IV Busulfan + 12 cGy FTBI + VP16 prior to allogeneic Bone Marrow Transplant
|Drug: busulfan Drug: cyclosporine Drug: etoposide Drug: mycophenolate mofetil Procedure: allogeneic bone marrow transplantation Procedure: allogeneic hematopoietic stem cell transplantation Procedure: peripheral blood stem cell transplantation Radiation: total-body irradiation|
- To determine the efficacy of a preparative regimen comprising dose targeted busulfan, etoposide, and fractionated total-body irradiation followed by allogeneic hematopoietic stem cell or bone marrow transplantation in patients with advanced hematologic malignancies.
- To determine the efficacy of this regimen in patients with acute myeloid leukemia in first remission with unfavorable cytogenetics.
- To evaluate the early and late toxicities of this regimen.
- Preparative chemotherapy regimen: Patients receive busulfan IV over 2 hours once every 6 hours on days -14 to -8 for a total of 16 doses and etoposide IV on day -3.* NOTE: *Patients also receive oral or IV dilantin 1-3 times daily on days -18 to -5 for prophylaxis of grand mal seizures.
- Fractionated total-body irradiation (FTBI): Patients undergo FTBI on days -7 to -4 for a total of 10 fractions.
- Allogeneic transplantation: Patients undergo allogeneic peripheral blood stem cell transplantation or bone marrow transplantation on day 0.
- Graft-versus-host disease (GVHD) prophylaxis: Patients receive cyclosporine IV or orally on days -1 to 50 followed by a taper to day 180 in the absence of GVHD. Patients also receive mycophenolate mofetil orally or IV over 2 hours twice daily on days 0-27, followed by a taper until day 56.
After completion of study treatment, patients are followed annually for 2 years.
