Research Study Description

This phase II trial studies the side effects and best dose of total-body irradiation when given together with fludarabine phosphate followed by a donor peripheral stem cell transplant in treating patients with myelodysplastic syndromes (MDS) or myeloproliferative disorders (MPD). Giving low doses of chemotherapy, such as fludarabine phosphate, and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cancer cells. Giving chemotherapy or radiation therapy before or after transplant also stops the patient's immune system from rejecting the donor's stem cells. The donated stem cells may replace the patient's immune cells and help destroy any remaining cancer cells (graft-versus-tumor effect). Sometimes the transplanted cells from a donor can also make an immune response against the body's normal cells. Giving cyclosporine and mycophenolate mofetil after the transplant may stop this from happening.

- Paroxysmal nocturnal hemoglobinuria (PNH): Patients with the non-aplastic form of PNH (cellular bone marrow) who have had a history of life-threatening complications of their disease including thrombotic events, severe hemolysis or Budd Chiari syndrome are eligible; other patients may be considered following approval at PCC and approval by the Principal investigator

- Matched Related Donor: Related to the patient and is genotypically or phenotypically HLA-identical

- Matched Related Donor: Donor age < 75 yrs unless cleared by institutional PI

- Matched Related Donor: Capable of giving written, informed consent

- Matched Related Donor: Donor must consent to PBSC mobilization with G-CSF and apheresis

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

- a.) Matched for HLA-A, B, C, DRB1 and DQB1 by high resolution typing;

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

- Unrelated 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

- HLA Matched Related Donor: G-CSF mobilized peripheral blood mononuclear cell (PBMC) only will be permitted as a hematopoietic stem cell (HSC) source on this protocol

- HLA Matched Unrelated Donor: Donor must consent to PBSC mobilization with G-CSF and apheresis; bone marrow unrelated donors are not eligible for this protocol

Other eligibility criteria may apply.

Exclusions (conditions that would prevent participation in this study)

- Organ dysfunction as defined by the following:

- * Symptomatic coronary artery disease or cardiac ejection fraction < 35% (or, if unable to obtain ejection fraction, shortening fraction of < 26%); if shortening fraction is < 26% a cardiology consult is required with the principal investigator (PI) having final approval of eligibility; ejection fraction is required if age > 50 years or there is a history of anthracycline exposure or history of cardiac disease

- * Diffusing capacity of the lung for carbon monoxide (DLCO) < 35%, TLC < 35%, forced expiratory volume (FEV)1 < 35% and/or receiving supplementary continuous oxygen; the FHCRC PI of the study must approve of enrollment of all patients with pulmonary nodules

- * Liver function abnormalities: Patient with clinical or laboratory evidence of liver disease will be evaluated for the cause of liver disease, its clinical severity in terms of liver function, bridging fibrosis, and the degree of portal hypertension; the patient will be excluded if he/she is found to have fulminant liver failure, cirrhosis of the liver with evidence of portal hypertension, alcoholic hepatitis, esophageal varices, a history of bleeding esophageal varices, hepatic encephalopathy, uncorrectable hepatic synthetic dysfunction evinced by prolongation of the prothrombin time, ascites related to portal hypertension, bacterial or fungal liver abscess, biliary obstruction, chronic viral hepatitis with total serum bilirubin > 3mg/dL, or symptomatic biliary disease

- Bone marrow documenting blast count >= 10% or >= 5% in CMML patients who have progressed beyond CMML1 and received myelosuppressive chemotherapy

- Patients with active non-hematologic malignancies (except non-melanoma skin cancers); this exclusion does not apply to patients with non-hematologic malignancies that do not require therapy
