Brief Summary
This phase II trial studies how well reduced intensity donor stem cell transplant works in treating patients with hematologic malignancies. Giving chemotherapy and total-body irradiation before a donor peripheral blood stem cell transplant helps stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and 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. The donated stem cells may also replace the patient's immune cells and help destroy any remaining cancer cells. 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 after the transplant may stop this from happening. Once the donated stem cells begin working, the patient's immune system may see the remaining cancer cells as not belonging in the patient's body and destroy them. Giving an infusion of the donor's white blood cells (donor lymphocyte infusion) may boost this effect.

Outcome Measures
Primary Outcomes (1)
Overall Survival (OS) in Patients With Haploidentical Family Donors With Hematological Malignancies in Morphological or Radiographic Remission or With Chemosensitive, Indolent Diseases
The primary null hypothesis is that 2 year OS rate is at most 35%. This hypothesis will be rejected if the 95% confidence interval for year OS rate computed from the estimated Kaplan-Meier survival curves will be entirely above 0.35.

Study Arms (1)
Treatment (Allogeneic PBSCT)
EXPERIMENTALREDUCED INTENSITY CONDITIONING: Patients receive fludarabine phosphate IV over 60 minutes on days -11 to -8 and busulfan IV over 3 hours on days -10 to -9. Patients undergo TBI on day -6. Patients also receive cyclophosphamide IV over 2 hours on days -3 and -2. TRANSPLANTATION: Patients undergo DLI on day -6 and CD-34+ allogeneic PBSCT on day 0. GVHD PROPHYLAXIS: Beginning on day -1, patients receive tacrolimus IV or PO with taper beginning on day 42. Patients also receive mycophenolate mofetil IV BID on days -1 to 28.

Eligibility Criteria
You may qualify if:
- Any patient with hematologic or oncologic diagnosis in which allogeneic HSCT is thought to be beneficial, and in whom front-line therapy has already been applied. Patients treated on this protocol will be without morphological evidence of disease (complete remission or "CR"), or if the patient has evidence of disease, the patient must have had at least a good partial response (PR) to the most recent therapy and the disease must be chemoresponsive.
- Patients treated on this study will have:
- Acute leukemia in 1st or 2nd CR
- MDS (myelodysplastic syndrome), specific subtypes of RA (refractory anemia) or RARS (refractory anemia with ringed sideroblasts) subtypes.
- Hodgkin or Indolent Non-Hodgkin's lymphoma with chemosensitive disease
- Myeloma without morphological evidence of disease, or a deep PR to the most recent therapy
- Myeloproliferative disorders with at least a PR to current therapy
- Aplastic Anemia
- A hematological or oncological disease (not listed) that meets the criteria reviewed above (in CR or with a good PR).
- Patients must have a related donor who is HLA mismatched at 2, 3, or 4 antigens at the HLA-A; B; C; DR loci in the GVHD direction. (Patients with related donors who are HLA identical or are a 1-antigen mismatch may be treated on this therapeutic approach, but will have their outcomes will not be part of the statistical aims of the study (see Summary section).
- Patients must adequate organ function:
- LVEF (Left ventricular end diastolic function) of \>50%
- DLCO (Diffusing Capacity of the Lung for Carbon Monoxide ) ≥50% of predicted corrected for hemoglobin
- Adequate liver function as defined by a serum bilirubin \<1.8, AST or ALT \< 2.5X upper limit of normal
- Creatinine Clearance of ≥ 60 mL/min
- +10 more criteria
You may not qualify if:
- Human immunodeficiency virus (HIV) positive
- Active involvement of the central nervous system with malignancy
- Inability to obtain informed consent
- Pregnancy
- Patients with life expectancy of =\< 6 months for reasons other than their underlying hematologic/oncologic disorder
- Patients who have received alemtuzumab or anti-thymocyte globulin (ATG) within 8 weeks of the transplant admission; (documented by the absence of these agents in the medical record)
- Patients with evidence of another malignancy, exclusive of a skin cancer that requires only local treatment, should not be enrolled on this protocol
