SOHO State of the Art Updates and Next Questions | Current and Emerging Novel Treatments for Marginal Zone Lymphoma.

Marginal zone lymphoma (MZL) is a heterogeneous disease representing 7% to 10% of non-Hodgkin lymphomas (NHL). There are no clear guidelines defining the need for treatment initiation and no standardized therapeutic approach for patients with MZL. Previously, many treatments were extrapolated from clinical trials that mainly enrolled patients with follicular lymphoma and did not have statistical power to show treatment efficacy specifically in MZL patients. Currently, the field is moving toward conducting specific trials in MZL patients with specific inclusion criteria for each MZL subtype, assessing response distinctively in FDG avid and nonavid MZL tumors and using MZL-relevant primary endpoints. Herein I briefly describe these changes, summarize previous therapeutic studies in MZL and present preliminary publicly available data on novel emerging treatments, including bispecific antibodies, antibody drug conjugates and novel targeted therapies.
