Research Study Description

This randomized phase III trial studies how well graft-vs-host disease (GVHD) prophylaxis works in treating patients with hematologic malignancies undergoing unrelated donor peripheral blood stem cell transplant. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant (PBSCT) 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 total-body irradiation (TBI) together with fludarabine phosphate (FLU), cyclosporine (CSP), mycophenolate mofetil (MMF), or sirolimus before transplant may stop this from happening.

Eligibility Criteria (must meet the following to participate in this study)

Genders Eligible for Study: Both

- Ages > 50 years with hematologic malignancies treatable by unrelated hematopoietic cell transplant (HCT)

- Ages =< 50 years of age with hematologic diseases treatable by allogeneic HCT who through pre-existing medical conditions or prior therapy are considered to be at high risk for regimen related toxicity associated with a high dose transplant (> 40% risk of transplant related mortality [TRM]); this criterion can include patients with a HCT-comorbidity index (CI) score of >= 1; transplants should be approved for these inclusion criteria by the principal investigators at the collaborating centers and at the Fred Hutchinson Cancer Research Center (FHCRC); all children < 12 years must be discussed with the FHCRC principal investigator (PI) prior to registration

- Ages =< 50 years of age with chronic lymphocytic leukemia (CLL)

- Ages =< 50 years of age with hematologic diseases treatable by allogeneic HCT who refuse a high-dose HCT; transplants must be approved for these inclusion criteria by the principal investigators at the collaborating centers and at FHCRC

- The following diseases will be permitted although other diagnoses can be considered if approved by PCC or the participating institutions' patient review committees and the principal investigators

- * Aggressive non-Hodgkin lymphomas (NHL) and other histologies such as diffuse large B cell NHL: not eligible for autologous HCT, not eligible for high-dose allogeneic HCT, or after failed autologous HCT

- * Mantle cell NHL: may be treated in first complete remission (CR); (diagnostic lumbar puncture [LP] required pre-transplant)

- * Low grade NHL: with < 6 month duration of CR between courses of conventional therapy

- * CLL: must have either:

- *** Failed to meet National Cancer Institute (NCI) Working Group criteria for complete or partial response after therapy with a regimen containing FLU (or another nucleoside analog, e.g. 2-Chlorodeoxyadenosine [2-CDA], pentostatin) or experience disease relapse within 12 months after completing therapy with a regimen containing FLU (or another nucleoside analog);

- *** Failed FLU-cyclophosphamide (CY)-Rituximab (FCR) combination chemotherapy at any time point; or

- *** Have "17p deletion" cytogenetic abnormality; patients should have received induction chemotherapy but could be transplanted in 1st CR; or

- *** Patients with a diagnosis of CLL (or small lymphocytic lymphoma) or diagnosis of CLL that progresses to prolymphocytic leukemia (PLL), or T-cell CLL or PLL

- * Hodgkin lymphoma: must have received and failed frontline therapy

- * Multiple myeloma: must have received prior chemotherapy; consolidation of chemotherapy by autografting prior to nonmyeloablative HCT is permitted

- * Acute myeloid leukemia (AML): must have < 5% marrow blasts at the time of transplant

- * Acute lymphocytic leukemia (ALL): must have < 5% marrow blasts at the time of transplant

- * Chronic myeloid leukemia (CML): Patients in CP1 must have failed or be intolerant of tyrosine-kinase inhibitors (TKI); patients beyond CP1 will be accepted if they have < 5% marrow blasts at time of transplant

- * Myelodysplasia (MDS)/myeloproliferative syndrome (MPS): Patients must have < 5% marrow blasts at time of transplant

- * Waldenstrom's macroglobulinemia: must have failed 2 courses of therapy

- DONOR: FHCRC matching allowed will be grades 1.0 to 2.1: Unrelated donors who are prospectively:

- * Matched for human leukocyte antigen (HLA)-A, B, C, DRB1 and DQB1 by high resolution typing

- * Only a single allele disparity will be allowed for HLA-A, B, or C as defined by high resolution typing

- DONOR: Donors are excluded when preexisting immunoreactivity is identified that would jeopardize donor hematopoietic cell engraftment; this determination is based on the standard practice of the individual institution; the recommended procedure for patients with 10 of 10 HLA allele level (phenotypic) match is to obtain a panel reactive antibody (PRA) screens to class I and class II antigens for all patients before HCT; if the PRA shows > 10% activity, then flow cytometric or B and T cell cytotoxic cross matches should be obtained; the donor should be excluded if any of the cytotoxic cross match assays are positive; for those patients with an HLA Class I allele mismatch, flow cytometric or B and T cell cytotoxic cross matches should be obtained regardless of the PRA results; a positive anti-donor cytotoxic crossmatch is an absolute donor exclusion

- DONOR: Patient and donor pairs homozygous at a mismatched allele in the graft rejection vector are considered a two-allele mismatch, i.e., the patient is A*0101 and the donor is A*0102, and this type of mismatch is not allowed

- DONOR: Only filgrastim (G-CSF) mobilized PBSC only will be permitted as a hematopoietic stem cell (HSC) source on this protocol

Other eligibility criteria may apply.

Exclusions (conditions that would prevent participation in this study)

- Patients with rapidly progressive intermediate or high grade NHL

- Central nervous system (CNS) involvement with disease refractory to intrathecal chemotherapy

- Presence of circulating leukemic blasts (in the peripheral blood) detected by standard pathology for patients with AML, ALL or CML

- Fungal infections with radiological progression after receipt of amphotericin B or active triazole for greater than 1 month

- Cardiac ejection fraction < 35% (or, if unable to obtain ejection fraction, shortening fraction of < 26%); ejection fraction is required if age > 50 years or there is a history of anthracycline exposure or history of cardiac disease; patients with a shortening fraction < 26% may be enrolled if approved by a cardiologist

- Diffusing capacity of carbon monoxide (DLCO) < 40%, total lung capacity (TLC) < 40%, forced expiratory volume in one second (FEV1) < 40% and/or receiving supplementary continuous oxygen

- The addition of cytotoxic agents for "cytoreduction" with the exception of tyrosine kinase inhibitors (such as imatinib), cytokine therapy, hydroxyurea, low dose cytarabine, chlorambucil, or rituxan will not be allowed within three weeks of the initiation of conditioning

- DONOR: Donor (or centers) who will exclusively donate marrow

- DONOR: Donors who are HIV-positive and/or, medical conditions that would result in increased risk for G-CSF mobilization and harvest of PBSC
