In the validation using the MER cohort of 192 MZL patients, 5y PFS was 57% (95% CI 51-64). Applying the MZL-IPI to the MER, 41(21%), 113 (59%), and 38 (20%) patients were classified as LRG, IRG, and HRG, respectively. B Conclusions: b MZL-IPI is a new validated prognostic score for all patients with MZL who are considered for systemic treatment. [Extracted from the article]

Regarding the B initial workup b , while at least one imagery was offered in 97% of patients, SP 18 sp FDG-PET/CT (EMZL 78%, SMZL 62%, NMZL 78%) was performed more frequently than CT-scan at baseline (EMZL 73%, SMZL 62%, NMZL 71%), although 47% patients underwent both procedures. Diagnosis of MZL was mostly evoked by general practitioners (48%) but patients were finally treated by hematologists (98%). B Background: b Marginal Zone Lymphomas (MZL) are a heterogeneous group of lymphomas that include three subtypes: extranodal MZL (EMZL), splenic MZL (SMZL) and nodal MZL (NMZL).

Introduction: Considering the notable advances made in the treatment of lymphoma, assessment of health-related quality of life (HRQoL) of lymphoma patients has become a critical aspect to consider both in clinical research and routine practice. However, there is paucity of information about lymphoma specific HRQoL profile at diagnosis., Patients and Methods: HRQoL at diagnosis was assessed for 3922 adult patients with newly diagnosed high-grade (HG) (n = 1994), low-grade (LG) (n = 1053) non-Hodgkin (NHL) and Hodgkin (HL) (n = 875) lymphomas included in REal world dAta in LYmphoma and Survival in Adults (REALYSA, NCT03869619), a prospective non-interventional multicentric cohort in France. Disease-specific HRQoL aspects were assessed with three validated EORTC questionnaires, namely, the QLQ-NHL-HG29, the QLQ-NHL-LG20 and the QLQ-HL27, for patients with NHL-HG, NHL-LG and HL, respectively., Results: We confirmed the high-level of completion of these questionnaires in REALYSA cohort, ranging from 84 % for QLQ-HG29 to 88 % for QLQ-HL27. The proportion of patients with impaired global health status was as follows: T-cell NHL, 67 %; diffuse large B-cell (DLBCL), 62 %; Burkitt, 61 %; HL, 53 %; marginal zone, 49 %; mantle cell, 48 %; follicular, 47 %. Multivariable regression analyses for DLBCL, follicular and HL showed that gender, performance status and B symptoms were independently associated with all HRQoL dimensions. However, a variable effect of age and stage were observed among these three subtypes., Conclusions: A comprehensive analysis was made describing the HRQoL profile of newly diagnosed patients with different types of lymphomas. Our data may help to enhance the interpretation of HRQoL results in future studies using the recently validated EORTC lymphoma specific questionnaires., Competing Interests: Declaration of Competing Interest AA had a consultancy or advisory role for Astrazeneca and Gilead/LKite, outside the submitted work.

Abstract: Use of surrogates as primary end points is commonplace in hematology/oncology clinical trials. As opposed to prognostic markers, surrogates are end points that can be measured early and yet can still capture the full effect of treatment, because it would be captured by the true outcome (eg, overall survival). We discuss the level of evidence of the most commonly used end points in hematology and share recommendations on how to apply and evaluate surrogate end points in research and clinical practice. Based on the statistical literature, this clinician-friendly review intends to build a bridge between clinicians and surrogacy specialists., (© 2024 American Society of Hematology.
