[Medical simulation training for bone marrow harvesting from a healthy donor for an allogeneic hematopoietic cell transplant (SFGM-TC)].

This workshop presents the recommendations of the Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC) for simulation-based training on bone marrow harvesting from healthy donors. Due to the decline in bone marrow harvests in favor of peripheral stem cells, a loss of expertise has been observed among younger hematologists. The training consists of an online theoretical component and a hands-on workshop using a mannequin at the PRESAGE simulation center at the Lille University School of Medicine.

Use of two general-purpose scales to assess clinical pharmacy activities in a cell transplantation unit.

Introduction: The general-purpose rating scales used by clinical pharmacists to rate their activities have not been extensively studied in specialist care units. This study aims to describe drug-related problems (DRPs) and pharmacist interventions (PIs) in a French hematopoietic cell therapy (HCT) unit and to evaluate the PIs' likely clinical, economic, and organizational impacts.

Methods: We retrospectively assessed all DRPs reported and all PIs issued between December 2018 and December 2021.

Graft-versus-host disease after anti-CD19 chimeric antigen receptor T-cell therapy following allogeneic hematopoietic cell transplantation: a transplant complications and paediatric diseases working parties joint EBMT study.

In patients diagnosed with B-acute lymphoblastic leukemia (B-ALL) or B-non-Hodgkin's lymphoma (B-NHL) relapsing after allogeneic stem cell transplantation (allo-HCT), it is a standard practice to perform anti-CD19 chimeric antigen receptor (CAR) T-cell therapy. When collected from the patient after allo-HCT, the produced CAR-T cells are likely to be donor T-cell-derived, creating unknown safety risks due to their potential allo-reactivity. We therefore performed an EBMT registry-based study on the incidence of graft-versus-host disease (GvHD) in this setting.

Allogeneic hematopoietic cell transplantation for therapy-related myeloid neoplasms arising following treatment for multiple myeloma: a retrospective study on behalf of the Chronic Malignancies Working Party of the EBMT.

Therapy-related myeloid neoplasms (t-MN) are a complication of multiple myeloma (MM) treatment. Our retrospective, EBMT registry study included 157 such patients allografted (allo-HCT) between 2006 and 2018. Most patients (130) had a prior autologous HCT.

[Real-life evaluation of the care pathway of patients eligible for axicabtagene ciloleucel treatment: Analysis of a multicenter retrospective cohort (IMPA-CT study)].

The arrival of CAR-T cell treatments in Europe in 2018 has considerably changed the clinical and logistical management of lymphoma patients. The aim of this study is to evaluate pathways of patients eligible for axicabtagene ciloleucel (axi-cel), particularly previously and afterwards of its administration, stages that are currently poorly documented in the literature. Ninety-eight patients from eleven French qualified centers eligible for axi-cel treatment between June 2020 and February 2021 were retrospectively included.

Directionality of HLA-DP permissive mismatches improves risk prediction in HCT for acute leukemia and MDS.

HLA-DP permissive mismatches can be assigned a direction according to their immunopeptidome divergence across core and noncore subsets. Noncore permissive graft-versus-host mismatches show significantly reduced risks of relapse without increased nonrelapse mortality compared with allele-matched pairs.

Pitfalls in definitions on respiratory viruses and particularities of Adenovirus infection in hematopoietic cell transplantation patients: Recommendations from the EBMT practice harmonization and guidelines committee.

In 2023, the EBMT Practice harmonization and Guidelines Committee partnered with the EBMT Infection Diseases Working Party (IDWP) to undertake the task of delivering best practice recommendations, aiming to harmonize by expert consensus, the already existing definitions and future epidemiological and clinical studies among centers of the EBMT network. To attain this objective, a group of experts in the field was convened. The workgroup identified and discussed some critical aspects in definitions of community-acquired respiratory viruses (CARV) and adenovirus (ADV) infections in recipient of hematopoietic cell transplant (HCT).

Unrelated donor transplantation with posttransplant cyclophosphamide vs ATG for myelodysplastic neoplasms.

It has been reported in prospective randomized trials that antithymocyte globulin (ATG)-based graft-versus-host disease (GVHD) prophylaxis has benefits in the setting of allogeneic hematopoietic stem cell transplantation (allo-HSCT) with unrelated donors (UDs). However, the optimal GVHD prophylaxis strategy has been challenged recently by the increasing use of posttransplant cyclophosphamide (PTCY). We report from the European Society for Blood and Marrow Transplantation registry the outcomes of 960 patients with myelodysplastic neoplasms who underwent allo-HSCT from UD with PTCY or ATG as GVHD prophylaxis.

Adenovirus infections after allogeneic hematopoietic cell transplantation in children and adults: a study from the Infectious Diseases Working Party of the European Society for Blood and Marrow Transplantation.

The objective of the study was the analysis of clinical types, outcomes, and risk factors associated with the outcome of adenovirus (ADV) infection, in children and adults after allo-HCT. A total number of 2529 patients (43.9% children; 56.

[Preventive and therapeutic strategies for relapse after hematopoietic stem cell transplant for pediatric AML (SFGM-TC)].

Treatment of pediatric high-risk acute myeloid leukemia (AML), defined either on molecular or cytogenetic features, relies on bone marrow transplant after cytologic remission. However, relapse remains the first post-transplant cause of mortality. In this 13 session of practice harmonization of the francophone society of bone marrow transplantation and cellular therapy (SFGM-TC), our group worked on recommendations regarding the management of post-transplant relapse in AML pediatric patients based on international literature, national survey and expert opinion.

Donor lymphocyte infusion after allogeneic haematopoietic cell transplantation for haematological malignancies: basic considerations and best practice recommendations from the EBMT.

Since the early description of three patients with relapsed leukaemia after allogeneic haematopoietic cell transplantation (HCT) who obtained complete remission after donor lymphocyte infusions (DLIs), the added value of this procedure to induce or maintain graft-versus-leukaemia immunity has been undisputed. For more than 30 years, DLIs have become common practice as prophylactic, pre-emptive, or therapeutic immunotherapy. However, as with many aspects of allogeneic HCT, centres have developed their own routines and practices, and many questions related to the optimal applications and toxicity, or to the immunobiology of DLI induced tumour-immunity, remain.

French early nationwide idecabtagene vicleucel chimeric antigen receptor T-cell therapy experience in patients with relapsed/refractory multiple myeloma (FENIX): A real-world IFM study from the DESCAR-T registry.

Idecabtagene vicleucel (ide-cel), a chimeric antigen receptor T-cell therapy targeting B-cell maturation antigen (BCMA), received early access program (EAP) authorization in France in April 2021 for relapsed/refractory multiple myeloma (RRMM). We conducted a real-world registry-based multicentre observational study in 11 French hospitals to evaluate ide-cel outcomes. Data from 176 RRMM patients who underwent apheresis between June 2021 and November 2022 were collected from the French national DESCAR-T registry.

Mismatched related donor allogeneic haematopoietic cell transplantation compared to other donor types for Ph+ chronic myeloid leukaemia: A retrospective analysis from the Chronic Malignancies Working Party of the EBMT.

Allogeneic haematopoietic cell transplantation (allo-HCT) remains an option for tyrosine kinase inhibitor-resistant chronic myeloid leukaemia (CML) in first chronic phase (CP1) and high-risk patients with advanced disease phases. In this European Society for Blood and Marrow Transplantation (EBMT) registry-based study of 1686 CML patients undergoing first allo-HCT between 2012 and 2019, outcomes were evaluated according to donor type, particularly focusing on mismatched related donors (MMRDs). Median age at allo-HCT was 46 years (IQR 36-55).
