Brief Summary
The purpose of this study is to determine whether thymic shielding during total body irradiation can be given and whether it will reduce the risk of infections in Fanconi Anemia patients undergoing alternate donor (not a matched sibling) stem cell transplants.

Outcome Measures
Primary Outcomes (1)
Number of Patients Who Exhibited Hematopoietic Recovery and Engraftment
Calculated from Day 1 of hematopoietic cell transplant to Day 42 post-transplant. Hematopoietic recovery and engraftment is defined as the first of three consecutive days the patient's absolute neutrophil count is greater than or equal to 0.5X10\^9/Liter.
Day 42 after hematopoietic cell transplant
Secondary Outcomes (8)
Number of Patients Who Exhibited Secondary Graft Failure
Day 100 after hematopoietic cell transplant
Number of Patients With Acute Graft Versus-Host Disease (aGVHD)
Day 100 after hematopoietic cell transplant
Number of Patients With Chronic Graft Versus-Host Disease (GVHD)
1 year after hematopoietic cell transplant
Number of Patients Who Exhibited Regimen-related Toxicity (RRT)
1 year after hematopoietic cell transplant
Immune Reconstitution - Mean Value (1 Year)
1 year post-transplant.
- +3 more secondary outcomes
Study Arms (1)
HSCT Patients
EXPERIMENTALPatients who received total body irradiation (450 cGy \[centigray\]) with thymic shielding prior to chemotherapy regimen and Hematopoietic Stem Cell Transplant (HSCT)
Interventions
Bone marrow failure may be treated by giving patients stem cells that come from someone else. This is called a stem-cell transplant. As part of the transplant process, patients receive high doses of chemotherapy and/or radiation to treat their underlying disease. As one of its effects, this treatment also kills the healthy stem cells that are already in the marrow. The transplant provides new stem cells for the patient from a healthy donor; that replace the bone marrow and allow the blood counts to recover.
protecting the thymus during total body radiation (450 cGy administered)
Six days before the stem cells are given (day -6), subjects will receive total body irradiation with thymic shielding. Thymic shielding is done by placing a piece of lead on the chest during the irradiation treatment so that the irradiation beams do not go to the thymus.
Day -5 through Day -2, subjects will receive a chemotherapy regimen of Fludarabine, Cyclophosphamide via central line
Eligibility Criteria
You may qualify if:
- Patients must be less than (\<) 18 years of age with a diagnosis of Fanconi anemia.
- Patients must have an HLA-A, B, DRB1 identical unrelated donor or less than or equal to (≤)1 antigen mismatched related (non-HLA-matched sibling) or \<1 antigen mismatched unrelated UCB donor. Patients and donors will be typed for HLA-A and B using serological or molecular techniques and for DRB1 using high resolution molecular typing.
- Patients with FA must have aplastic anemia (AA), myelodysplastic syndrome without excess blasts, or high risk genotype as defined below.
- Aplastic anemia is defined as having at least one of the following when not receiving growth factors or transfusions
- Platelet count \<20 x 10\^9/L
- ANC \<5 x 10\^8/L
- Hgb \<8 g/dL
- Myelodysplastic syndrome with multilineage dysplasia with or without chromosomal anomalies
- High risk genotype (e.g. IVS-4 or exon 14 FANCC mutations, or BRCA1 or 2 mutations)
- Adequate major organ function including
- Cardiac: ejection fraction greater than (\>)45%
- Hepatic: bilirubin, AST/ALT, ALP \<2 x normal
- Karnofsky performance status \>70% or Lansky performance status \>50%
- Women of child-bearing age must be using adequate birth control and have a negative pregnancy test
You may not qualify if:
- Available HLA-genotypically identical related donor
- History of gram negative sepsis or systemic fungal infection (proven or suspected based on radiographic studies)
- Refractory anemia with excess blasts, or leukemia
- Active central nervous system (CNS) leukemia at time of hematopoietic cell transplant (HCT)
- History of squamous cell carcinoma of the head/neck/cervix within 2 years of HCT
- Pregnant or lactating female
- Prior radiation therapy preventing use of total body irradiation (TBI) 450 centigray (cGy)

Limitations and Caveats
Study ended early as thymic shielding was found to be safe. Therefore, a new study was designed using thymic shielding.
