About
This phase II trial is studying how well umbilical cord blood transplant from a donor works in treating patients with hematological cancer. Giving chemotherapy and total-body irradiation (TBI) before a donor umbilical cord blood 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 an unrelated donor, that do not exactly match the patient's blood, 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 (called graft-versus-host disease). Giving cyclosporine and mycophenolate mofetil before and after transplant may stop this from happening.

PRIMARY OBJECTIVES:
I. Estimate probability of one year survival.
II. Demonstrate equivalent or improved engraftment rates with a non-anti-thymocyte globulin (ATG) based conditioning regimen. Patients will be considered graft failure/rejections provided they meet any of the criteria listed below:
- Absence of 3 consecutive days with neutrophils >= 500/ul combined with host cluster of differentiation (CD)3 peripheral blood chimerism >= 50% at day 42
- Absence of 3 consecutive days with neutrophils >= 500/ul under any circumstances at day 55
- Death after day 28 with neutrophil count < 100/ul without any evidence of engraftment (< 5% donor CD3)
- Primary autologous count recovery with < 5% donor CD3 peripheral blood chimerism at count recovery and without relapse
SECONDARY OBJECTIVES:
I. Six month non-relapse mortality.
II. Overall incidence of graft failure/rejection. Patients will be considered graft failure/rejections provided they meet any of the criteria listed below:
- Absence of 3 consecutive days with neutrophils >= 500/ul combined with host CD3 peripheral blood chimerism >= 50% at day 42
- Absence of 3 consecutive days with neutrophils >= 500/ul under any circumstances at day 55
- Death after day 28 with neutrophil count < 100/ul without any evidence of engraftment (< 5% donor CD3)
- Primary autologous count recovery with < 5% donor CD3 peripheral blood chimerism at count recovery and without relapse
III. Kinetics of chimeric reconstitution.
IV. Incidence of neutrophil engraftment by day 42.
V. Incidence of platelet engraftment by six months.
VI. Incidence of grade II-IV and III-IV acute graft-versus-host disease (GvHD) at day 100.
VII. Incidence of one year chronic GvHD.
VIII. Incidence of clinically significant infections at 6 months, 1 year, 2 years.
IX. Probability of one and two year survival.
X. Incidence of one and two year relapse or disease progression.
XI. Fred Hutchinson Cancer Research Center (FHCRC) patients: Kinetics of immune reconstitution, with both functional and quantitative assays.
XII. FHCRC patients: Examination of possible immunologic factors leading to emergence of a dominant unit.
OUTLINE:
CONDITIONING REGIMEN: Patients receive fludarabine phosphate intravenously (IV) over 1 hour on days -6 to -2 and cyclophosphamide IV over 1-2 hours on day -6. Patients undergo a lower dose of total-body irradiation (TBI) on day -1.
UMBILICAL CORD BLOOD TRANSPLANT: Patients undergo donor umbilical cord blood infusion on day 0.
IMMUNOSUPRESSIVE THERAPIES: Patients receive cyclosporine IV over 1 hour every 8-12 hours on days -3 to +180 and mycophenolate mofetil IV or orally (PO) every 8 hours on days 0 to +96.
After completion of study treatment, patients are followed periodically for up to 2 years.

DONOR: Cord blood (CB) donor selection will be based on institutional guidelines and in general should be selected to optimize both human leukocyte antigen (HLA) match and cell dose; additionally, CB grafts shall consist of one or two CB donors based on, but not exclusively determined by, cell dose (total nucleated cell [TNC]/kg and CD34/kg), HLA matching and disease status and indication for transplant; attending preference will be allowed for single versus double unit as well as the degree of mismatching based on patient specific factors, as long as the following minimum criteria are met:
-
HLA matching
- Minimum requirement: The CB graft(s) must be matched at a minimum at 4/6 HLA-A, B, DRB1 loci with the recipient. Therefore 0-2 mismatches at the A or B or DRB1 loci based on intermediate resolution A, B antigen and DRB1 allele typing for determination of HLA-match is allowed
- HLA-matching determined by high-resolution typing is allowed per institutional guidelines as long as the minimum criteria are met
-
Selection of two CB units is mandatory when a single cord blood unit does not meet the following criteria:
- Match grade 6/6; TNC Dose >= 2.5 x 10^7/kg
- Match grade 5/6 or 4/6; TNC dose >= 4.0 (+/- 0.5) x 10^7/kg
-
If two CB units are used, the total cell dose of the combined units must be at least 3.0 x 10^7 TNC per kilogram recipient weight based on pre-cryopreservation numbers, with each CB unit containing a MINIMUM of 1.5 x 10^7 TNC/kg
-
The minimum recommended CD34/kg cell dose should be 2 x 10^5 CD34/kg, total dose from a single or combined double
-
The unmanipulated CB unit(s) will be Food and Drug Administration (FDA) licensed or will be obtained under a separate investigational new drug (IND), such as the National Marrow Donor Program (NMDP) Protocol 10-CBA conducted under BB IND-7555 or another IND sponsored by (1) a participating institution or (2) an investigator at FHCRC or one of the participating institutions
-
FHCRC only: Up to 5% of cord blood product, when ready for infusion, may be withheld for research purposes as long as thresholds for infused TNC dose are met; threshold for double unit transplantation is >= 3.0 x 10^7/kg; these products will be used to conduct studies involving the immunobiology of double cord transplantation and kinetics of engraftment
-
