We report the results of an aggressive salvage regimen in 2 patients with advanced-stage leukemic-phase mantle cell lymphoma who were refractory to previous conventional therapies. We combined multiple phases of a cytoreductive regimen including rituximab and sequential high-dose treatment with autologous stem cell transplantation (ASCT). The regimen consisted of a debulking phase with fludarabine, idarubicin, high-dose cytarabine, and high-dose methotrexate; a mobilization and in vivo purging phase with rituximab, cyclophosphamide, and granulocyte colony-stimulating factor; high-dose sequential chemotherapy with etoposide, mitoxantrone, and melphalan followed by ASCT; and, finally, posttransplantation consolidation with rituximab for treatment of minimal residual disease. With this regimen, these 2 refractory patients with multiple poor prognostic factors are in complete remission at 41 and 42 months following transplantation. Although the fact that these 2 patients are still in remission beyond 3 years after ASCT is encouraging, we need a longer follow-up to comment on their long-term survival.
