About
Relapse remains a principle cause of treatment failure for patients with aggressive lymphoma after autologous transplantation. Non-myeloablative allogeneic transplantation allows patients to receive an infusion of donor cells in an attempt to induce a graft versus lymphoma effect. This study will assess the feasibility, safety and efficacy of the combination of autologous stem cell transplantation followed by non-myeloablative transplantation for patients with poor-risk aggressive lymphoma.
Full description
This is a phase II clinical trial investigating the feasibility, and efficacy of sequential autologous stem cell transplant followed by non-myeloablative allogeneic transplant for patients with poor risk lymphoma. Patients will be enrolled onto the trial when eligible and undergo standard high-dose chemotherapy with the combination with busulfan, cyclophosphamide, and etoposide followed by autologous stem cell transplant. After recovery of counts and clinical status, patients will then proceed to non-myeloablative allogeneic stem cell transplant using a fully matched related or unrelated donor.

Inclusion criteria
Patients with high-risk diffuse large B cell or transformed low grade lymphoma defined as:
Patients with any T-cell non-Hodgkin's lymphoma as defined as:
Patients with mantle cell lymphoma at any time in therapy
Patients with "double-hit" lymphoma as characterized by the presence of concurrent overexpression of Bcl-2 and c-myc
Patients with Hodgkin's lymphoma that is
Patients with CLL/SLL with 17p- cytogenetic abnormality
Age 18 years and greater
ECOG performance status 0-2
Ability to understand and the willingness to sign a written informed consent document.
Responsive disease to last therapy as determined by at least one of the following:
Minimum of 2 x 106 CD34+ cells / kg already collected and frozen. These stem cells may have been collected from PBSC pheresis, bone marrow harvest, or the combination.
Exclusion criteria
Patients will be re-evaluated after autologous transplant prior to proceeding to non-myeloablative transplant
Eligibility to proceed to allogeneic transplant Cannot be admitted for allogeneic transplant earlier than 40 days and no later than 180 days after autologous stem cell transplant.
HLA identical (A, B, C and DR) related or unrelated donor available. HLA typing of class I loci (HLA- A, B, C) will be based on complement dependent cytotoxicity assay or PCR of sequence specific oligonucleotide primers (SSOP). Typing of HLA class II (DRB1) will be based on PCR of sequence specific oligonucleotide primers (SSOP).
No need for intravenous hydration in the previous 2 weeks
Resolved mucositis
Renal, cardiac, pulmonary, and hepatic function meet standard criteria for nonmyeloablative SCT as listed below:
No intravenous antimicrobials within 2 weeks
No evidence of progressive disease, defined as a 25% increase from nadir in the sum of the product of the diameters (SPD) of any lymph node previously identified as abnormal prior to autologous transplant or the appearance of any new lymph node greater than 1.5 cm in greatest diameter, new bone marrow involvement, or new solid organ nodule greater than 1 cm in diameter. This restaging study will be performed at least 28 days after the autologous transplant and within 60 days prior to admission for allogeneic transplant. Status of stable disease (SD) is acceptable to proceed to allogeneic transplant.
