A systematic literature review and meta-analysis of radioimmunotherapy consolidation for patients with untreated follicular lymphoma.

Background: Follicular lymphoma (FL) is characterized by multiple relapses and progressively shorter response durations with subsequent therapies. Despite the development of numerous treatment strategies to reduce the risk of progression, optimal therapeutic strategies for patients with FL remain undefined. Radioimmunotherapy (RIT) with an anti-CD20 antibody linked to iodine-131 or to yttrium-90 has emerged as well-tolerated treatment after induction.
