Rituximab provides durable remission in a patient with refractory aggressive diffuse B-cell lymphoma failing salvage chemotherapy

The outcome of patients with aggressive refractory diffuse large B-cell lymphoma (DLCL) is generally poor. A 43-year-old female with DLCL, who relapsed after first line chemotherapy (CHOP-cyclophosphamide, doxorubicin, vincristine, and prednisone) and progressed despite salvage chemotherapy (EPOCH-etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin), was treated effectively with 8 cycles of Rituximab. She is without evidence of disease with a follow-up of 32 months. We report this case to bring to attention the possibility of sustained durable remission with single agent Rituximab in refractory DLCL.
