Mantle cell lymphoma (MCL) is a distinctive clinicopathologic entity and represents 5~10% of all non-Hodgkin's Lymphoma (NHL). The median survival of patients with MCL is only 3 years, and none of the available conventional chemotherapy regimens appear curative. Encouraging results have been reported with high dose chemotherapy with stem cell transplantation for its treatment. Particularly, alloSCT appears to induce durable remission via graft-versus-lymphoma (GVL) effect. Donor lymphocyte infusions (DLIs), by virtue of graft-versus-tumor effect, have been shown to induce remissions in leukemia that recurs after alloSCT. But GVL effect of DLI has not been clearly established in NHL. We describe a patient with relapsed MCL shortly after high dose chemotherapy with autoSCT who was successfully treated with alloPBSCT. The patient presented with diffuse GI and spleeninvolvement at the time of alloPBSCT. The patient received Bu/Cy/VP-16 as preparative regimen followed by alloPBSCT. The patient received cyclosporin and methotrexate as GVHD prophylaxis. Prednisone was added after grade II GVHD. The patient had partial response by D+64. To enhance GVL effect, the patient received G-CSF primed DLI serially at D+64 and D+92. Grade IV GVHD developed 19 days after 2nd DLI and was partially controlled with a combination of cyclosporin, prednisone and mycophenolate mofetil. Clinical complete remission was observed at D+112, and maintained till last follow-up day (D+515). Our findings suggest that alloSCT and stepwise DLIs may offer a curative approach to MCL.
