In brief

This phase II trial studies how well decitabine and total-body irradiation followed by donor bone marrow transplant and cyclophosphamide works in treating patients with relapsed or refractory acute myeloid leukemia. Giving decitabine and total-body irradiation before a donor bone marrow transplant 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 decitabine and total-body irradiation before the transplant together with high-dose cyclophosphamide, tacrolimus, and mycophenolate mofetil after the transplant may stop this from happening.

You may qualify if…

Patients must meet one of two disease criteria:
Acute myelogenous leukemia (AML) within one of the following categories:
Primary induction failure (PIF): patients who have not achieved a complete remission following initial diagnosis and after at least two induction cycles of chemotherapy consisting of cytarabine and an anthracycline or high-dose cytarabine
Relapsed AML: Patients are defined as having relapsed disease if they entered a complete remission confirmed with a bone marrow biopsy following initial treatment, and then were found to have morphological or cytogenetic evidence of recurrent disease on a subsequent bone marrow exam
Any complete remission (CR) 2 or greater: CR must be defined using a bone marrow exam taken at least 21 days since the last chemotherapy (including a methyltransferase inhibitor), and may include CRp (morphologic CR without peripheral platelet recovery)
CR1 with high-risk features: includes patients with treatment-related AML, secondary AML (following myelodysplastic syndrome (MDS) or myeloproliferative neoplasms (MPN)), high-risk cytogenetic or molecular phenotype (by National Comprehensive Cancer Network (NCCN) criteria)
Untreated AML (> 20% blasts on a bone marrow) arising from a previous confirmed diagnosis of MDS or MPN (excluding BCR-ABL (a genetic mutation) positive diseases).
Myelodysplastic syndromes within one of the following categories:
High-risk myelodysplastic syndrome (MDS) at diagnosis as defined by the International Prognostic Scoring System (IPSS) or World Health Organization (WHO) classification based Prognostic Scoring System (WPSS)
Transfusion dependent MDS (either red blood cells (RBC) or platelet dependent) without a hematologic response to at least 4 months of methyltransferase inhibitor (MTI) therapy; hematological response is defined as transfusion independence for two or more months
Progressive MDS following at least 4 months of MTI therapy; progression is defined as resumption of transfusion dependence after at least two months of transfusion independence OR increase of marrow blasts by 50% from pretreatment OR overall blasts over 10% of marrow cells at any time after treatment
Available related donor that is at least an allele level haplotype-match at human leukocyte antigen (HLA)- A, B, C, DP Beta 1 (DRB1) and DPB1 loci (DPB1 matching according to the "permissive - non-permissive" dichotomy as stated by University of Wisconsin (UW) Histocompatibility Laboratory); a minimum match of 5/10 loci is required; an unrelated donor search is not required for a patient to be eligible for this protocol
Karnofsky score of 60% or better (requires occasional assistance, but is able to care for most of his/her needs)
Diffusing capacity of the lungs for carbon monoxide (DLCO) (corrected for hemoglobin > 40%; and forced expiratory volume in one second (FEV1) > 50%
Ejection fraction (EF) >= 50% and no uncontrolled angina, symptomatic ventricular arrhythmias, or electrocardiogram (ECG) evidence of active ischemia
Serum creatinine within normal range for age, or if serum creatinine outside normal range, then renal function (estimated glomerular filtration rate (GFR) by modification of diet in renal disease (MDRD) formula) > 40 mL/min/1.73 m\^2
Women of child bearing potential must have a negative pregnancy test within 14 days prior to study registration and agree to use adequate birth control during study treatment
Voluntary written consent
Patients must be 28 days from the end of the last induction course or at least 14 days from completion of previous methyltransferase inhibitor therapy (azacitidine or decitabine) at the time of registration
DONOR: Donors must be at least HLA-haploidentical first degree relatives of the patients; eligible donors include biological parents, siblings, half-siblings or children
DONOR: Age >= 18 years and =< 60 years
DONOR: Donors must meet the selection criteria prior to the start of the recipient's pre-transplant conditioning regimen as defined by the Foundation for the Accreditation of Cell Therapy (FACT) and will be screened according to the American Association of Blood Banks (AABB) guidelines and UW Bone Marrow Transplant (BMT) program standard operating procedure (SOP)

You may not qualify if…

Active central nervous system (CNS) leukemia within two weeks of registration; patients with a history of CNS leukemia must have adequate treatment as defined by at least two negative spinal fluid assessments separated by at least one week; patients who have received cranial radiation therapy (XRT) must still be eligible to receive total body irradiation to 4 Gy
New or active infection as determined by fever, unexplained pulmonary infiltrate or sinusitis on radiographic assessment; infections diagnosed within 4 weeks of registration must be determined to be controlled or resolving prior to treatment
Active human immunodeficiency virus (HIV), hepatitis A, B or C infection
Allergy or hypersensitivity to agents used within the treatment protocol
DONOR: Recipient derived anti-donor high-titer (> 3000 MFI) HLA antibody as determined by Luminex assay
DONOR: Not suitable for donation according to UW BMT program donor selection SOP
