Radioimmunotherapy and secondary leukemia: A case report

Research output: Contribution to journalArticlepeer-review


This study describes a patient with a relapsed, diffuse, large B cell lymphoma (DLBCL) treated with radioimmunotherapy (RIT) with yttrium-90 (90Y)-ibritumomab tiuxetan (Zevalin®) who 5 months later developed acute myeloid leukemia (AML) with inversion of chromosome 16. Our data indicate that molecular biological techniques should be used in selected cases to integrate data obtained with standard cytogenetics: using RT-PCR we showed that inversion of chromosome 16 was already present before RIT, in striking contrast to the normal karyotype found with conventional cytogenetics. This approach will allow investigators to avoid misleading data and provide support for conclusions regarding the side effects of treatment.
