RATIONALE: Cyclophosphamide when added to tacrolimus and mycophenolate mofetil is safe and effective in preventing severe graft-versus-host disease (GvHD) in most patients with hematologic malignancies undergoing transplantation of bone marrow from half-matched (haploidentical) donors. This approach has extended the transplant option to patients who do not have matched related or unrelated donors, especially for patients from ethnic minority groups. The graft contains cells of the donor's immune system which potentially can recognize and destroy the patient's cancer cells (graft-versus-tumor effect). Rejection of the donor's cells by the patient's own immune system is prevented by giving low doses of chemotherapy (Fludarabine and cyclophosphamide) and total-body irradiation before transplant. Patients can experience low blood cell counts after transplant. Using stem cells and immune cells collected from the donor's circulating blood may result in quicker recovery of blood counts and may be more effective in therapy of the patient's disease than using bone marrow.
PURPOSE: This phase II trial is studying how well donor peripheral blood stem cell transplant works in treating patients with hematologic malignancies.
I.To demonstrate that use of PBSC in place of marrow as the source of lymphocytes and stem cells for nonmyeloablative transplants from related, haploidentical donors will not result in unacceptable rates of high-grade acute or chronic GvHD, nonrelapse mortality or relapse compared to historical data on nonmyeloablative transplants from unrelated donors.
I. Estimates of the rates of neutrophil and platelet recovery, number of RBC and platelet transfusions, incidences of graft failure, transplant-related toxicities, disease-free survival and overall survival.
Patients receive fludarabine IV over 30-60 minutes daily on days -6 through -2 and cyclophosphamide IV over 1-2 hours on days -6 , -5, and 3-4. Patients undergo total-body irradiation on day -1. Patients undergo donor peripheral blood stem cell transplant on day 0. Patients then receive tacrolimus IV or orally once or twice daily on days 5-180 (may be continued if active GvHD is present) and mycophenolate mofetil IV or orally three times daily on days 5-35 (may be continued if GvHD present).
Treatment continues in the absence of disease progression or unacceptable toxicity.

A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
Precursor of an alkylating nitrogen mustard antineoplastic and immunosuppressive agent that must be activated in the LIVER to form the active aldophosphamide. It has been used in the treatment of LYMPHOMA and LEUKEMIA. Its side effect, ALOPECIA, has been used for defleecing sheep. Cyclophosphamide may also cause sterility, birth defects, mutations, and cancer.
Transplantation of stem cells collected from the peripheral blood. It is a less invasive alternative to direct marrow harvesting of hematopoietic stem cells. Enrichment of stem cells in peripheral blood can be achieved by inducing mobilization of stem cells from the BONE MARROW.
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
