Résumé

Marginal Zone Lymphoma (MZL) comprises three subtypes: extranodal MZL (EMZL), splenic MZL (SMZL) and nodal MZL (NMZL). Since clinical trials have limited representativeness, there is a need for real-world data (RWD) evidence in MZL. Real-world data in Lymphoma and survival in Adults (REALYSA) is a prospective multicentric French cohort of newly diagnosed lymphoma patients. This study consists of the first abstraction of MZL patients prospectively included in REALYSA between 12/2018 and 01/2021 with at least 1 year of follow-up. It provides a landscape description of clinical characteristics, initial workup, quality of life and first-line therapy performed in routine practice. Among 207 included patients, 122 presented with EMZL, 51 with SMZL and 34 with NMZL. At baseline, median age was 67 years (range 28-96), and patients reported a favorable global health status (75/100 (IQR 58,83)) - which was higher in NMZL and lower in SMZL patients (p = 0.006). FDG-PET/CT was frequently performed at initial workup (EMZL 72%, SMZL 73%, NMZL 85%). Active surveillance was the initial management for 58 (28%) patients. The most prescribed therapies were rituximab-chlorambucil in the EMZL population (30%), rituximab monotherapy in the SMZL population (37%) and R-CHOP (24%)/bendamustine-rituximab (15%) in the NMZL population. At end of first line, overall response rate was 93% among treated patients with 75% of complete response. This French nationwide study provided for the first time prospective RWD on clinical characteristics, initial management and treatment response of MZL patients.
