We aim to report our experience with lenalidomide, bortezomib and dexamethasone therapy in a patient with MDS del(5q) and MM….She tolerated lenalidomide 10 mg daily, bortezomib 1.3 mg/m2 and dexamethasone once weekly of a 28-day cycle, with no treatment related complications. Reassessment of bone marrow following 6 cycles of treatment showed a partial response for MM and complete response for MDS.
