Linfoma di zona marginale: aggiornamento 2026 sulla diagnosi e sulla gestione.

DISEASE OVERVIEW: Marginal zone lymphoma (MZL) is a heterogeneous group of indolent mature B-cell neoplasms with classically three major subtypes: nodal, splenic, and extranodal MZL of mucosa-associated lymphoid tissue (MALT). DIAGNOSIS: Diagnosis and disease evaluation of MZL is further advanced by the use of genomic testing and PET/CT with emerging evidence for the use of circulating tumor DNA. The RECLASS classification system proposed a hierarchical approach to classifying MZL while the FIL-NF10 investigators introduced a fourth MZL subtype, disseminated MZL. Though the prognosis of MZL varies between subtypes and stages, the MZL IPI and FLIPI24 indices can be used for prognostication.
