Autologous Followed by Non-myeloablative Allogeneic Transplantation for Non-Hodgkin's Lymphoma
The approach to recurrent or primary refractory non-Hodgkin's lymphoma has been to treat
patients with second-line chemotherapy (usually 2-3 courses) for the purposes of
cytoreduction and to establish sensitivity to chemotherapy. Thereafter, peripheral blood
progenitor cells have been mobilized with cyclophosphamide and granulocyte colony
stimulating factor, apheresed and cryopreserved. Unfortunately, there are subgroups of
patients with poor outcomes using autologous transplantation including those with
transformed lymphoma as well as patients who do not attain a minimal disease state due to
chemoresistant disease.
In a group of 17 patients with transformed lymphoma who received autologous transplants at
Stanford University, the median EFS and OS were 1.48 and 2.7 years respectively with a
7-year survival of only 20%. In comparison, patients with chemosensitive follicular
lymphoma who received the same regimen also had a poor median EFS of 1.3 years, but the
median survival was 6.7 years. The outcomes for patients with chemotherapy-resistant
relapsed NHL is also poor with EFS in the range of 20% in many studies of autologous
transplantation.
These groups of patients have limited disease control and survival with standard
chemotherapy regimens, and although they often have excellent cytoreduction with the
high-dose chemotherapy regimen, relapse remains the primary cause of treatment failure. The
current trial utilizes a similar approach that we have taken with patients with multiple
myeloma, who appear to benefit from an allogeneic graft-versus-tumor effect, using a
combined autologous and non-myeloablative allogeneic transplant regimen to reduce
transplant-related complications. In addition, there are limited reports of using an
autologous/allogeneic approach for lymphoma patients using non-myeloablative allogeneic
transplants. Eligible patients will be treated with high-dose chemotherapy using BCNU,
etoposide, cytarabine and melphalan with autologous hematopoietic cell support as a method
of cytoreduction. Approximately 60-120 days after the autologous transplant, patients will
receive an allogeneic transplant using a preparative regimen of total lymphoid irradiation
and anti-thymocyte globulin in an attempt to develop a graft-versus-lymphoma effect.
