Summary

This study will investigate the safety and effectiveness of a modified stem cell transplant procedure for treating cancers of the blood and immune system. Patients with cancers and pre-cancerous conditions originating in blood or immune system cells can sometimes benefit greatly from, and even be cured by, transplants of stem cells (cells produced by the bone marrow that mature into blood cells). In addition to producing new bone marrow and restoring normal blood production and immunity, the donated cells fight any residual tumor cells that might have remained in the body, in what is called a graft-versus-tumor effect. However, severe problems, and sometimes death, may follow these transplants as a result of the high-dose chemotherapy and radiation that accompany the procedure. Also, donated immune system cells called T cells sometimes attack healthy tissues in a reaction called graft-versus-host-disease (GVHD), damaging organs such as the liver, intestines and skin. This study will use the following strategies to try to reduce these risks: * induction chemotherapy to reduce patient's immunity in an attempt to prevent rejection of the donated stem cells; * reduced-intensity conditioning chemotherapy that is easier for the body to tolerate and involves a shorter period of complete immune suppression; * donation of immune cells called T helper type 2 (Th2) cells instead of T cells to try to reduce the risk of serious GVHD; * treatment with methotrexate and cyclosporine to try to reduce the risk of serious GVHD. Patients between 12 and 75 years of age with non-Hodgkin's lymphoma, Hodgkin's lymphoma, multiple myeloma, chronic lymphocytic leukemia, chronic myelogenous leukemia, acute myelogenous leukemia, acute lymphocytic leukemia, myelodysplasia, idiopathic myelofibrosis, polycythemia vera, or chronic myelomonocytic leukemia may be eligible for this study. Candidates will have a medical history, physical and dental examinations, blood and urine tests (including a blood test for genetic match with the donor), lung and heart function tests, and X-ray studies. A bone marrow biopsy may be done to evaluate disease status. Patients with lymphoma may have a nuclear medicine test called a positron emission tomography (PET) scan. Participants will have a central venous line (large plastic tube) placed into a major vein. This tube can stay in the body and be used during the entire treatment period to deliver the donated stem cells and give medications, including chemotherapy and other drugs, antibiotics and blood transfusions, and to withdraw blood samples. Treatment will start with induction chemotherapy, which will include the drugs fludarabine, cyclophosphamide, etoposide, doxorubicin, vincristine, and prednisone. Some patients may also receive an antibody called rituximab. Patients will receive one to three cycles of this treatment, depending on their response to the drugs. (One cycle consists of 5 days on drug therapy followed by a 16-day rest period.) Several days before the transplant procedure, patients will start conditioning chemotherapy with cyclophosphamide and fludarabine. Three days after the conditioning therapy is completed, the stem cells will be infused. To help prevent GVHD, patients will take four doses of methotrexate (by vein) shortly after the transplant, and cyclosporine (by mouth or by vein) for about 6 months after the transplant. The average hospital stay for stem cell transplantation is 3 to 4 weeks. After discharge, patients will return for frequent follow-up visits for 3 months. Monthly visits will be scheduled for the next 3 months, then every 3 months for the next 18 months, and less frequently for a total of at least 5 years post-transplant. These visits will include bone marrow aspirates and biopsies, blood draws, and other tests to monitor disease status.

Eligibility Criteria

INCLUSION CRITERIA:

Inclusion Criteria Patient (Recipient):

Patients with hematologic malignancies, myelodysplasia, or myeloproliferative disorders, as summarized below:

Disease: Chronic Lymphocytic Leukemia; Disease Status: (a) Relapse post-fludarabine, (b) Non-Complete Remission (CR) after salvage regimen; Age: 18 to 75.

Disease: Hodgkin's and Non-Hodgkin's Lymphoma (all types, including Mantle Cell Lymphoma); Disease Status: (a) Primary treatment failure, (b) Relapse after autologous stem cell transplant (SCT), (c) Hepatosplenic gamma/delta T cell lymphoma; Age: 18 to 75.

Disease: Acute Myelogenous Leukemia; Disease Status: (a) In Complete Remission #1, with high-risk cytogenetics [abnormalities other than t(8;21), t(15;17), or inv(16)], (b) In Complete Remission #2 or greater; Age: 18 to 75.

Disease: Acute Lymphocytic Leukemia; Disease Status: (a) In Complete Remission #1, with high-risk cytogenetics [t(9;22) or bcr-abl rearrangement; t(4;11), 1(1;19), t(8;14)], (b) In Complete Remission #2 or greater; Age: 18 to 75.

Disease: Myelodysplastic Syndrome; Disease Status: (a) refractory anemia with excess blasts (RAEB), (b) refractory anemia with excess blasts in transformation (RAEB-T) (if blasts are less than 10% in marrow and blood after induction chemotherapy); Age: 18 to 75.

Disease: Myeloproliferative disorders; Disease Status: (a) Idiopathic myelofibrosis, (b) Polycythemia vera, (c) Essential thrombocytosis, (d) Chronic myelomonocytic leukemia; Age: 18 to 75.

Disease: Chronic Myelogenous Leukemia (CML); Disease Status: (a) Chronic phase CML, (b) Accelerated phase CML; Age 50 to 75; (c) Not eligible for myeloablative allogeneic HSCT; Age: 18 to 50.

Patients 18-75 years of age. Patients older than 75 years of age will be considered on an individual basis.

Consenting first degree relative matched at 6/6 human leukocyte antigen (HLA) antigens (A, B, and DR).

Patient or legal guardian must be able to give informed consent.

All previous therapy must be completed at least 2 weeks prior to study entry, and any grade 3 or 4 non-hematologic toxicity of previous therapy must be resolved to grade 2 or less, unless specified elsewhere.

Eastern Cooperative Oncology Group (ECOG) performance status equal to 0 or 1.

Life expectancy of at least 3 months.

Patients with acute leukemia must be in hematologic remission, defined as less than 5% blasts present in blood or bone marrow.

Left ventricular ejection fraction greater than 45% by either multi-gated acquisition (MUGA) scan or 2-D echo, obtained within 28 days of enrollment. The cumulative dose of doxorubicin received by patients will not be considered, as the cardiac ejection fraction appears to indicate the safe cumulative doxorubicin dose in the setting of etoposide phosphate, prednisone, vincristine, cyclophosphamide, and doxorubicin hydrochloride (EPOCH)-based chemotherapy.

Diffusing capacity for carbon monoxide (DLCO) greater than 50% of the expected value when correlated for hemoglobin (Hb), obtained within 28 days of enrollment.

Creatinine less than or equal to 1.5 mg/dl and creatinine clearance greater than or equal to 50 ml/min/1.73 m(2).

Serum total bilirubin less than 2.5 mg/dl, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) values less than or equal to 2.5 times the upper limit of normal. Values above these levels may be accepted, at the discretion of the principal investigator (PI) or study chairman, if such elevations are thought to be due to liver involvement by malignancy. If these values do not normalize during induction chemotherapy, such patients will not be eligible for the transplant phase of the protocol, and will thus be taken off study.

Minimum absolute neutrophil count of 1,000 cells/microliter and minimum platelet count (without transfusion) of 20,000/m
