Brief Summary

One of two different doses of thymoglobulin will allow bone marrow engraftment with minimal Graft-versus-Host Disease and allow adequate immune response to allow the transplanted stem cells to replace the tumor cells.

Detailed Description

This randomized phase II trial studies how well giving low dose total-body irradiation (TBI) with anti-thymocyte globulin followed by donor peripheral blood stem cell transplant (PBSCT) works in treating patients with hematologic malignancies. Giving reduced intensity total-body irradiation and anti-thymocyte globulin before a donor peripheral blood stem cell transplant helps stop the growth of 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. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving total-body irradiation together with antithymocyte globulin before transplant may stop this from happening.

Inclusion Criteria

  • Adequate cardiac, pulmonary, renal and hepatic function for transplant
  • Negative serology for HIV
  • Negative serum pregnancy test
  • Patients who have received therapeutic radiation to a localized field will be eligible, provided critical structure tolerance doses have not been exceeded

Exclusion Criteria
  • Evidence of uncontrolled viral, fungal, bacterial infection
  • Evidence of active meningeal or CNS disease

Event-free Survival2 years
Relapse2 year relapse rate (%)

Patients with different disease relapses was determined according to current clinical standards based on the disease. For example, AML or MDS relapse is determined by a bone marrow biopsy. Multiple myeloma relapse requires a number of labs and/or biopsy to diagnose such as SPEP, UPEP, immunofixation, serum and urine light chains. In lymphoma disease is followed using CT and/or PET scans.
