Brief Summary
This phase II trial studies how well a 2-step approach to stem cell transplant works in treating patients with blood cancers. Giving chemotherapy and total body irradiation before a lymphocyte (white blood cell) and stem cell transplant helps stop the growth of cells in the bone marrow including normal blood-forming cells (stem cells) and cancer cells. By giving the donor cells in two steps, the dose of lymphocytes given can be tightly controlled and they can be made more tolerant to the body. When the healthy lymphocytes and 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 called graft versus host disease. Giving tacrolimus and mycophenolate mofetil may stop this from happening.

For chimerism rates, the method of Atkinson and Brown will be used to allow for the two-stage design. Will be presented with corresponding 95% confidence intervals.
At day +28
Secondary Outcomes (4)
Donor T cell chimerism
At day +90
Relapse rate
At 1 year post-hematopoietic stem cell transplantation (HSCT)
Incidence of grades II-IV graft versus host disease (GVHD)
Within 1 year of HSCT
Rate of treatment-related mortality (TRM)
At 1 year post-HSCT
Other Outcomes (1)
Rate of cytomegalovirus
Up to 100 days
Study Arms (1)
Treatment (TBI, DLI, chemotherapy, HSCT, tacrolimus, MMF)
EXPERIMENTALDescription CONDITIONING REGIMEN: Participants undergo TBI BID on days -9 to -6. TRANSPLANT: Participants receive donor lymphocytes IV on day -6 after the last dose of TBI. CONDITIONING REGIMEN: Participants receive cyclophosphamide IV on days -3 and -2. TRANSPLANT: Participants undergo hematopoietic stem cell transplantation on day 0. GVHD PROPHYLAXIS: Participants receive tacrolimus IV beginning on day -1 with taper beginning on day 42 in the absence of GVHD, a suspicion of GVHD, or previous history of GVHD requiring a taper delay. Participants also receive mycophenolate mofetil IV BID beginning on day -1 through day 28 in the absence of GVHD.

Eligibility Criteria
You may qualify if:
- Provide signed and dated informed consent form.
- Have a hematological malignancy or any type of dyscrasia in which allogeneic HSCT is thought to be beneficial.
- Have a related donor who is no more than a 1-antigen mismatch at the human leukocyte antigen (HLA)-A; B; C; DR loci in the GVHD direction with the patient. (Patients with a syngeneic donor may be treated on this therapeutic approach, but their outcomes will not be part of the statistical aims of the study.
- LVEF (left ventricular end diastolic function) of \>= 45%.
- DLCO (diffusing capacity of the lung for carbon monoxide) \>= 50% of predicted corrected for hemoglobin.
- FEV-1 (forced expiratory volume at 1 second \>= 50% of predicted.
- Serum bilirubin =\< 1.8.
- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) =\< 2.5 x upper limit of normal.
- Creatinine clearance of \>= 60 mL/min.
- Have a Hematopoietic Cell Transplant Comorbidity Index (HCT-CI) score =\< 5 points (patients with greater than 5 points will be allowed for trial with approval of the principal investigator \[PI\] and at least 1 co-investigator \[co-I\] not on the primary care team of the patient). This is an adjustment to account for healthy patients who meet the spirit of this protocol but have histories that result in higher than HCT-CI 5 points. An example is a patient with a solid tumor malignancy in their remote history (adds 3 points to HCT-CI total) where the treatment for the malignancy occurred years to decades before and there has been complete recovery of toxicities.
- Have a Karnofsky performance score (KPS) \>= 80%.
- Women of reproductive potential (defined as women under the age of 50 years still menstruating within 2 months of HSCT despite past history of chemotherapy) will be counseled to use highly effective contraception including oral, intramuscular (IM), or patch contraceptives, intrauterine device (IUD), diaphragm, cervical cap, or contraceptive implant. Pharmacological avoidance of pregnancy and suppression of menstruation may be instituted during the HSCT inpatient stay.
- Men will be asked to abstain from sexual relations during the treatment period of the HSCT stay.
- DONOR: All donors are selected and screened for their ability to provide adequate infection-free apheresis products for the patient in a manner that does not put the donor at risk for negative consequences.
You may not qualify if:
- Be human immunodeficiency virus (HIV) positive.
- Be pregnant or breastfeeding.
