CONDITIONING REGIMEN: Patients receive fludarabine phosphate IV on days -4 to -2 and undergo low-dose TBI on day 0.

TRANSPLANTATION: Patients undergo allogeneic PBSCT on day 0.

IMMUNOSUPPRESSION: Patients receive cyclosporine PO BID or IV BID or TID on days -3 to 56 with taper to day 77 or 180, and mycophenolate mofetil PO or IV BID on days 0-27.

DLI: At least 2 weeks after completion of immunosuppression, patients with \> 5% donor CD3+ T cells and no evidence of GVHD receive donor lymphocytes IV over 30 minutes. Patients may receive up to 3 DLIs at increasing cell doses in the absence of GVHD.

This clinical trial studies fludarabine phosphate, low-dose total-body irradiation, and peripheral blood stem cell transplant followed by donor lymphocyte infusion in treating older patients with chronic myeloid leukemia. Giving chemotherapy and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer cells. It may also 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 cyclosporine and mycophenolate mofetil after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them (called graft-versus-tumor effect). Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

PRIMARY OBJECTIVES:

I. To determine if mixed hematopoietic chimerism can be safely established using a non-myeloablative conditioning regimen in patients \> 65 years of age with chronic myeloid leukemia (CML) in chronic or accelerated phase who have human leukocyte antigen (HLA) identical related donors.

II. To determine if mixed chimerism, established with non-myeloablative conditioning regimens, can be converted to full donor hematopoietic chimerism by infusions of donor lymphocytes (DLI), and thereby produce an immunologic cure of the malignancy.

OUTLINE:

CONDITIONING REGIMEN: Patients receive fludarabine phosphate intravenously (IV) on days -4 to -2 and undergo low-dose total-body irradiation (TBI) on day 0.

TRANSPLANTATION: Patients undergo allogeneic peripheral blood stem cell transplantation (PBSCT) on day 0.

IMMUNOSUPPRESSION: Patients receive cyclosporine orally (PO) twice daily (BID) or IV BID or thrice daily (TID) on days -3 to 56 with taper to day 77 or 180, and mycophenolate mofetil PO or IV BID on days 0-27.

DLI: At least 2 weeks after completion of immunosuppression, patients with \> 5% donor cluster of differentiation (CD)3+ T cells and no evidence of graft-versus-host disease (GVHD) receive donor lymphocytes IV over 30 minutes. Patients may receive up to 3 DLIs at increasing cell doses in the absence of GVHD.

After completion of study treatment, patients are followed up periodically for 5 years.

Fludarabine Phosphate, Low-Dose Total-Body Irradiation, and Peripheral Blood Stem Cell Transplant Followed by Donor Lymphocyte Infusion in Treating Older Patients With Chronic Myeloid Leukemia

Induction of Mixed Hematopoietic Chimerism Using Fludarabine, Low Dose TBI , PBSC Infusion and Post-Transplant Immunosuppression With Cyclosporine and Mycophenolate Mofetil to be Followed by Donor Lymphocyte Infusion In Patients With Chronic Myeloid Leukemia in Chronic and Accelerated Phases: A Multi-center Study

All unexpected toxicities will be summarized and reported.

Estimated and corresponding confidence intervals presented. Mixed chimerism is detection of donor T cells (CD3+) and granulocytes (CD33+), as proportion of total T cell and granulocyte population of \> 5% and \< 95% in peripheral blood. Full donor chimerism is \> 95% donor CD3+ T cells. Increasing donor chimerism is absolute increase of 20% of CD3+ T cells over chimerism evaluation of previous month. Decreasing donor chimerism is absolute decrease of 20% of CD3+ T cell chimerism over previous month. Low donor chimerism is \< 40% CD3+ T cells after HSCT.

Reported in a descriptive manner and confidence intervals will be presented for all estimates.

Defined as absolute neutrophil count \[ANC\] \< 500 for \> 2 days, platelets \< 20,000 for \> 2 days.
