R-ICE and Lenalidomide in Treating Patients With First-Relapse/Primary Refractory Diffuse Large B-Cell Lymphoma

This phase I/II trial studies the side effects and best dose of lenalidomide when given together with rituximab-ifosfamide-carboplatin-etoposide (R-ICE) and to see how well they work in treating patients with diffuse large B-cell lymphoma that has returned after a period of improvement (relapsed) and that has not responded to previous treatment (refractory). Drugs used in chemotherapy, such as rituximab, ifosfamide, carboplatin, etoposide, and lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving lenalidomide with R-ICE may be a better treatment for patients with diffuse large B-cell lymphoma.
