Reduced Intensity Conditioning and Stem Cell Transplant in Treating Patients with Blood Cancer

Status: Active


This phase II trial studies how well reduced intensity conditioning (a short course of chemotherapy) and stem cell transplant work in treating patients with blood cancer. 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. Giving reduced intensity conditioning and total body irradiation before a donor blood stem cell transplant helps to stop the growth of cells in the bone marrow, including normal blood-forming cells (stem cells) and cancer cells with shorter recovery and fewer side effects.

  • Leukemia or myelodysplastic syndrome (MDS) in aplasia; these patients may be taken to transplant if after induction therapy they remain with aplastic bone marrow and no morphological or flow-cytometry evidence of disease >= 28 days post-therapy; these high risk patients will be analyzed separately

  • Relapsed large-cell lymphoma, mantle-cell lymphoma and Hodgkin lymphoma that is chemotherapy sensitive and has failed or ineligible for an autologous transplant
  • Burkitt’s lymphoma in CR2 or subsequent CR
  • Relapsed T-cell lymphoma that is chemotherapy sensitive in CR/partial response (PR) that has failed or ineligible for an autologous transplant
  • Natural Killer cell malignancies
  • Relapsed chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), marginal zone B-cell lymphoma, follicular lymphoma, which have progressed within 12 months of achieving a partial or complete remission; patients who had remissions lasting > 12 months, are eligible after at least two prior therapies; patients with bulky disease should be considered for debulking chemotherapy before transplant; patients with refractory disease are eligible, unless bulky disease and an estimated tumor doubling time of less than one month
  • Lymphoplasmacytic lymphoma is eligible after initial therapy if chemotherapy sensitive
  • Relapsed multiple myeloma that is chemotherapy sensitive and has failed or ineligible for an autologous transplant
  • Bone marrow failure syndromes, except for Fanconi anemia
  • Absence of decompensated congestive heart failure, or uncontrolled arrhythmia and left ventricular ejection fraction > 40%; for children that are not able to cooperate with multi-gated acquisition (MUGA) and echocardiography, such should be clearly stated in the physician’s note
  • Diffusing capacity of the lungs for carbon monoxide (DLCO), forced expiratory volume 1 (FEV1), forced vital capacity (FVC) > 40% predicted, and absence of oxygen (O2) requirements; for children that are not able to cooperate with pulmonary function tests (PFTs), a pulse oximetry with exercise should be attempted; if nether test can be obtained it should be clearly stated in the provider’s note
  • Transaminases < 5 x upper limit of normal (ULN) and total bilirubin =< 2.5 mg/dL except for patients with Gilbert’s syndrome or hemolysis
  • Creatinine =< 2.0 mg/dL (adults) and creatinine clearance > 40 mL/min (pediatrics); adults with a creatinine > 1.2 or a history of renal dysfunction must have estimated creatinine clearance > 40 ml/min/1.73m^2
  • Sexually active females of childbearing potential and males with partners of child-bearing potential must agree to use adequate birth control during study treatment
  • Voluntary written consent (adult; legally authorized representative on behalf of cognitively impaired adult; or parent/guardian with presentation of the minor information sheet, if appropriate)
