Targeted therapy with conjugated and unconjugated monoclonal antibodies for non-Hodgkin's lymphoma has revolutionized the approach to this disease. The efficacy and low toxicity of these agents have allowed introduction of this strategy in the early stages of therapy. Longer follow-up is needed before validating the safety of these agents. Since monoclonal antibodies are being given as front-line therapy, it is important to identify all potential adverse events. We report a case of secondary acute myelogenous leukemia (AML) with 11q23 cytogenetic abnormality and mixed lymphoid leukemia (MLL) gene expression in a patient treated with Y90 labeled anti-CD20 antibody (Zevalin). The patient was not exposed to topoisomerase II inhibitors. Our observations suggest a relationship between 11q23 leukemia and radioimmunotherapy (RAIT) and further studies are needed.
