Abstract

The marginal zone non-Hodgkin's lymphomas are a recently defined group of related low-grade B cell malignancies whose natural history is heterogeneous. The optimal therapy is often unclear, particularly for the subset of patients with disseminated disease that behaves aggressively. We have retrospectively analyzed the outcomes of 11 patients with chemosensitive but disseminated marginal zone lymphomas who underwent uniform conditioning with cyclophosphamide and total body irradiation followed by bone marrow transplantation (BMT) with anti-B cell monoclonal antibody-purged autologous bone marrow between January 1994 and September 1999. All patients had stage IV disease and received multiple chemotherapy regimens prior to autologous BMT. Only 36% were in complete remission at the time of bone marrow harvest, and 36% had overt bone marrow infiltration at that time. Two treatment-related deaths occurred between 100 days and 6 months. Three patients relapsed and died of disease. One patient developed and died of myelodysplasia. Five patients remain in continuous complete remission at a median follow-up of 52 months (45%). The median progression-free survival for these patients was 56 months, with median overall survival 58 months. The only significant predictor of disease-free and overall survival was age at the time of transplant; no patient under 45 at the time of transplant has relapsed or died of any cause (P = 0.003). Outcomes of autologous BMT in patients with disseminated marginal zone NHL are similar to those in follicular NHL, and suggest that certain patients may experience prolonged disease-free survival.
