Long-term efficacy and toxicity results of the FLUMIZ trial (fludarabine and mitoxantrone followed by yttrium-90 ibritumomab tiuxetan in untreated follicular lymphoma).

The radiosensitivity of lymphomas as well as the local targeted delivery of high doses of radiation make radioimmunotherapy (RIT) an attractive therapeutic option. RIT is indeed an underestimated tool. In follicular lymphoma (FL), RIT represents one of the most effective single agents. The two most commonly used radioimmunoconjugates are Y-ibritumomab tiuxetan (Zevalin ) and I-tositumomab, both based on murine anti-Cd20 antibodies. Annals of Oncology letters to the editor
