The use of allogeneic BMT in patients with relapsed non-Hodgkin lymphoma (NHL) offers the advantage of tumor-free bone marrow and possibly a 'graft-versus-lymphoma effect' which may decrease the risk of recurrence. However, allogeneic BMT also poses an increased risk of death due to graft-versus-host disease (GVHD) which can be ameliorated by T cell depletion. We performed a retrospective review of 37 patients who underwent T cell-depleted allogeneic BMT for aggressive and indolent NHL between 1988 and 1996. Polymerase chain reaction (PCR) was used to identify indolent NHL patients with the BCL2/IgH translocation which served as a marker of residual disease. Sixteen of 37 patients (44%) are alive and progression-free with a median follow-up of 4.4 years (range 1-10.3). The incidence of grade 2-4 acute GVHD was 36% and extensive chronic GVHD developed in 12%. Patients with aggressive NHL have an overall PFS of 33% (12-54%); those with chemotherapy-resistant and sensitive disease have PFS of 17% (0-47%), and 40% (15-65%) respectively at 5 years. Patients with indolent histologies have overall PFS of 62% (37-86%); those with chemotherapy-resistant and sensitive disease have PFS of 55% (25-85%) and 80% (45-100%) respectively at 5 years. Eight patients with indolent disease had a BCL2/IgH translocation detectable by PCR. Five of these eight patients remain alive and progression free at a median of 6.5 years after BMT (range 2.1-7.4 years), four of whom remain PCR positive from 1.7 to 2.9 years after transplantation. We conclude that T cell-depleted allogeneic BMT poses a low risk for death due to GVHD, and should be considered for patients with relapsed and refractory indolent NHL.
