The rationale for this trial is to demonstrate the feasibility and safety of allogeneic HCT for patients with chemotherapy-sensitive hematological malignancies and coincident HIV-infection. In particular, the trial will focus on the 100-day non-relapse mortality as an indicator of the safety of transplant in this patient population. Correlative assays will focus upon the incidence of infectious complications in this patient population, the evolution of HIV infection and immunological reconstitution. Where feasible (and when this can be accomplished without compromise of either the donor quality or the timeliness of transplantation), an attempt will be made to identify donors who are homozygotes for the delta32 mutation for CCR5.
The study is designed to evaluate the feasibility and safety of reduced-intensity and fully-ablative allogeneic hematopoietic cell transplantation (HCT) for patients with hematological malignancies or myelodysplastic syndromes (MDS) who have HIV infection. The goal of the study is to assess the 100 day Non-relapse Mortality as well as immunological reconstitution in this patient population. Where feasible, an attempt will be made to identify human leukocyte antigen (HLA)-compatible hematopoietic stem cell donors who are homozygotes for the delta32 mutation of the chemokine receptor 5 (CCR5delta32). Patients will undergo a treatment plan review prior to registration on the trial. All patients will undergo allogeneic HCT from a matched sibling or unrelated donor.

RIC Regimen (Flu/Bu): Fludarabine total dose: 120-180 mg/m\^2, Busulfan: ≤ 8 mg/kg PO or 6.4 mg/kg IV). Recommended regimen: * Days -6 to -2: Flu (30 mg/m\^2/day, total dose of 150 mg/m\^2) * Days -5 to -4: Busulfan (4mg/kg/day PO or 3.2 mg/kg IV, 130 mg/m\^2/day, total dose of 8 mg/kg PO or 6.4 mg/kg IV, or 260 mg/m\^2 IV, respectively) Patients with a creatinine clearance of 40-70 ml/min (measured or calculated) should have a 20 percent dose reduction in Fludarabine dosage. Busulfan will be dosed according to the recipient's ideal body weight (IBW), unless the patient weighs more than 125 percent of IBW, in which case the drug will be dosed according to the adjusted IBW.
RIC Regimen (Flu/Mel): Fludarabine total dose: 120-180 mg/m\^2, Melphalan total dose: less than or equal to 150 mg/m\^2. Recommended regimen: * Days -5 to -2: Flu (30mg/m\^2/day, total dose of 120 mg/m\^2) * Day -1: Mel (140mg/m\^2) Patients with a creatinine clearance of 40-70 ml/min (measured or calculated) should have a 20 percent dose reduction in Fludarabine dosage.
MAC Regimen (Bu/Flu): Fludarabine total dose: 120-180mg/m\^2 Busulfan total dose less than or equal to 16mg/kg PO or 12.8 mg/kg IV. Recommended regimen: * Days -5 to -2: Busulfan (4 mg/kg/day PO with Bu Css 900 plus/equal to 100 ng/mL (or per institutional standard), 3.2 mg/kg/day IV or 130 mg/m\^2/day IV; total dose of 16 mg/kg, 12.8 mg/kg or 520 mg/m\^2, respectively) * Days -5 to -2: Flu (30 mg/m\^2/day, total dose of 120 mg/m\^2) Patients with a creatinine clearance of 40-70 ml/min (measured or calculated) should have a 20 percent dose reduction in Fludarabine dosage. Busulfan will be dosed according to the recipient's ideal body weight (IBW), unless the patient weighs more than 125 percent of IBW, in which case the drug will be dosed according to the adjusted IBW.
MAC Regimen (Cy/TBI): Cyclophosphamide total dose: 120 mg/kg, Fractionated TBI total dose: 1200-1420 cGy Recommended regimen: * Days -7 to -4: TBI (total dose of 1200-1420 cGy) * Days -3 to -2: Cy (60 mg/kg/day, total dose of 120 mg/kg) Cyclophosphamide will be dosed according to the recipient's ideal body weight (IBW), unless the patient weighs less than IBW, in which case the drug will be dosed according to the actual body weight.

Percentage of Participants With Non-Relapse Mortality
The events for non-relapse mortality are death due to any cause other than relapse of the underlying malignancy.
Time frame: Day 100, 1 Year, and 2 Years Post-transplant
Percentage of Participants With Overall Survival
Overall survival is defined as the time from transplant to death from any cause.
Time frame: Six months, 1 Year, and 2 Years Post-transplant
Percentage of Participants With Relapse/Progression
Relapse/Progression is defined as relapse or progression of the primary malignancy.
Time frame: 1 Year Post-transplant
Primary Cause of Death
Time frame: Up to 2 Years Post-transplant
Disease Status
Patients will be assessed for disease status at Day 100 post-HCT, classified as complete remission, partial remission, stable disease, and relapse/progressive disease.
Time frame: Day 100 Post-transplant
Percentage of Participants Recovering Hematologic Function
Recovery of hematologic function is described by the time to neutrophil and platelet recovery. Time to neutrophil recovery will be the first of three consecutive days of \> 500 neutrophils/μL following the expected nadir. Time to platelet engraftment will be described by the date when platelet count is \> 20,000/μL for the first of three consecutive labs with no platelet transfusions 7 days prior.
Time frame: Days 28 and 100 Post-transplant
Chimerism
Donor T-cell and myeloid chimerism will be described separately by conditioning regimen intensity (myeloablative or reduced intensity) according to proportions with mixed chimerism (5-95% donor cells out of all), full chimerism (\>95% donor cells), or graft rejection (\<5% donor cells).
