To measure how frequently and to what degree a complication of transplant cell acute graft versus host disease (GvHD) occurs.

This study evaluated whether TLI-ATG conditioning followed by allogeneic hematpoietic cell transplant (HCT), which has provided excellent overall survival for patients with relapsed lymphoma after failed autologous HCT, provides a similar benefit in the setting of elderly patients with hematologic malignancies.

INCLUSION CRITERIA:

• Any patient with one of the following hematolymphoid malignancies or syndromes in whom allogeneic hematopoietic stem cell transplant (HST) is warranted. Specific disease categories include:

  • Indolent advanced stage non-Hodgkin lymphomas
  • Mantle cell lymphoma
  • Chronic lymphocytic leukemia
  • Hodgkin disease (Hodgkin's lymphoma)
  • Acute leukemias in complete remission
  • Aplastic anemia
  • Paroxysmal nocturnal hemoglobinuria
  • Myelodysplastic or myeloproliferative syndromes.
  • Other selected malignancies/disorders may also be considered but must be approved by the transplant team and the Principal Investigator.

• Age > 50 years, or if < 50 years of age, considered to be at high risk for regimen-related toxicity associated with conventional myeloablative transplants due to pre-existing medical conditions or prior therapy.

• A fully human leukocyte antigen (HLA)-identical sibling or matched unrelated donor is available. Potential participants with one antigen mismatched donors can be considered but only after discussion with the transplant team and the Principal Investigator.

• Participant must be competent to give consent.

EXCLUSION CRITERIA:

• Progressive hematolymphoid malignancies despite conventional therapies, or acute leukemias not in complete remission.
• Uncontrolled central nervous system (CNS) involvement with disease
• Fertile men or women unwilling to use contraceptive techniques during and for 12 months following treatment
• Pregnant
• Cardiac ejection fraction < 30%
• Uncontrolled cardiac failure
• Pulmonary diffusing capacity (DLCO) < 40% predicted
• Elevation of bilirubin to > 3 mg/dL
• Transaminases > 4 x the upper limit of normal
• Creatinine clearance < 50 cc/min (24-hour urine collection)
• Karnofsky performance score < 60%
• Poorly controlled hypertension on multiple antihypertensives
• Documented fungal disease that is progressive despite treatment
• HIV-positive. Other viral infections, ie, Hepatitis B- and C- positive, evaluated on a case-by-case basis
• Psychiatric disorders or psychosocial problems which in the opinion of the primary physician or Principal Investigator would place the patient at unacceptable risk from this regimen.
