Prognostic impact of number of induction courses to attain complete remission in patients with acute myeloid leukemia transplanted with either a matched sibling or human leucocyte antigen 10/10 or 9/10 unrelated donor:An Acute Leukemia Working Party European Society for Blood and Marrow Transplantation study

Introduction: For the majority of patients with acute myeloid leukemia (AML) an allogeneic stem cell transplant (SCT) in first complete remission (CR) is preferred. However, whether the number of courses required to achieve CR has a prognostic impact is unclear. It is unknown which factors remain important in patients requiring more than one course of induction to attain remission. Methods: This Acute Leukaemia Working Party study from the European Society for Blood and Marrow Transplantation identified adults who received an allograft in first CR from either a fully matched sibling or 10/10 or 9/10 human leucocyte antigen (HLA)‐matched unrelated donor (HLA‐A, HLA‐B, HLA‐C, HLA‐DR, or HLA‐DQ). Univariate and multivariate analyses were undertaken to identify the prognostic impact of one or two courses of induction to attain CR. Results: A total of 4995 patients were included with 3839 (77%) patients attaining a CR following one course of induction chemotherapy (IND1), and 1116 patients requiring two courses (IND2) to attain CR. IND2 as compared to IND1 was a poor prognostic factor in a univariate analysis and remained so in a multivariate Cox model, resulting in an increased hazard ratio of relapse (1.38; 95% confidence interval [CI], 1.16–1.64; p = .0003) and of death (1.27; 95% CI, 1.09–1.47; p = .002). Adverse prognostic factors in a multivariate analysis of the outcomes of patients requiring IND2 included age, FLT3‐ITD, adverse cytogenetics, and performance status. Pretransplant measurable residual disease retained a prognostic impact regardless of IND1 or IND2. Conclusion: Initial response to chemotherapy as determined by number of courses to attain CR, retained prognostic relevance even following SCT in CR

Hematopoietic stem cell transplantation for DLBCL: a report from the European Society for Blood and Marrow Transplantation on more than 40,000 patients over 32 years

Autologous(auto-) and allogeneic(allo-) hematopoietic stem cell transplantation (HSCT) are key treatments for relapsed/refractory diffuse large B-cell lymphoma (DLBCL), although their roles are challenged by CAR-T-cells and other immunotherapies. We examined the transplantation trends and outcomes for DLBCL patients undergoing auto-/allo-HSCT between 1990 and 2021 reported to EBMT. Over this period, 41,148 patients underwent auto-HSCT, peaking at 1911 cases in 2016, while allo-HSCT saw a maximum of 294 cases in 2018. The recent decline in transplants corresponds to increased CAR-T treatments (1117 cases in 2021). Median age for auto-HSCT rose from 42 (1990-1994) to 58 years (2015-2021), with peripheral blood becoming the primary stem cell source post-1994. Allo-HSCT median age increased from 36 (1990-1994) to 54 (2015-2021) years, with mobilized blood as the primary source post-1998 and reduced intensity conditioning post-2000. Unrelated and mismatched allo-HSCT accounted for 50% and 19% of allo-HSCT in 2015-2021. Three-year overall survival (OS) after auto-HSCT improved from 56% (1990-1994) to 70% (2015-2021), p 40,000 transplants, providing insights for evaluating emerging DLBCL therapies

Outcome after allogeneic stem cell transplantation with haploidentical versus HLA-matched donors in patients with higher-risk MDS.

peer reviewedAllogeneic hematopoietic stem cell transplantation remains the best curative option for higher-risk myelodysplastic syndrome. The presence of monosomal karyotype and/or complex karyotype abnormalities predicts inferior survival after allo-SCT in MDS patients. Haploidentical allo-SCT has been increasingly used in acute leukemia (AL) and has similar results as using HLA-matched donors, but data on higher-risk MDS is sparse. We compared outcomes in 266 patients with higher-risk MDS after HLA-matched sibling donor (MSD, n = 79), HLA-matched unrelated donor (MUD, n = 139) and HLA haploidentical donor (HID, n = 48) from 2010 to 2019. Median donor age differed between the three groups (p < 0.001). The overall survival was significantly different between the three groups with a better OS observed in the MUD group (p = 0.014). This observation could be explained by a higher progression-free survival with MUD (p = 0.014). The cumulative incidence of grade 2-4 acute GvHD was significantly higher in the HID group (p = 0.051). However, in multivariable analysis, patients transplanted using an HID had comparable mortality to patients transplanted using a MUD (subdistribution hazard ratio [sHR]: 0.58 [0.32-1.07]; p = 0.080) and a MSD ([sHR]: 0.56 [0.28-1.11]; p = 0.094). MUD do not remain a significant positive predictor of survival, suggesting that beyond the donor-recipient HLA matching, the donor age might impact recipient outcome

Bone marrow graft versus peripheral blood graft in haploidentical hematopoietic stem cells transplantation: a retrospective analysis in1344 patients of SFGM-TC registry.

peer reviewedThe use of peripheral blood (PB) or bone marrow (BM) stem cells graft in haploidentical hematopoietic stem cell transplantation with post-transplant cyclophosphamide (PTCy) for graft-versus-host disease (GVHD) prophylaxis remains controversial. Moreover, the value of adding anti-thymoglobulin (ATG) to PTCy is unknown. A total of 1344 adult patients received an unmanipulated haploidentical transplant at 37 centers from 2012 to 2019 for hematologic malignancy. We compared the outcomes of patients according to the type of graft, using a propensity score analysis. In total population, grade II-IV and III-IV acute GVHD (aGVHD) were lower with BM than with PB. Grade III-IV aGVHD was lower with BM than with PB + ATG. All outcomes were similar in PB and PB + ATG groups. Then, in total population, adding ATG does not benefit the procedure. In acute leukemia, myelodysplastic syndrome and myeloproliferative syndrome (AL-MDS-MPS) subgroup receiving non-myeloablative conditioning, risk of relapse was twice greater with BM than with PB (51 vs. 22%, respectively). Conversely, risk of aGVHD was greater with PB (38% for aGVHD II-IV; 16% for aGVHD III-IV) than with BM (28% for aGVHD II-IV; 8% for aGVHD III-IV). In this subgroup with intensified conditioning regimen, risk of relapse became similar with PB and BM but risk of aGVHD III-IV remained higher with PB than with BM graft (HR = 2.0; range [1.17-3.43], p = 0.012)

Indications de l’autogreffe de cellules souches hématopoïétiques dans la polyradiculonévrite inflammatoire démyélinisante chronique : recommandations de la Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC)

International audienceChronic Inflammatory Demyelinating Polyneuropathy (CIDP) is a chronic autoimmune disease involving the peripheral nervous system, characterized by focal and segmental demyelination accounting for neurological deficit. CIDP diagnosis is based on several criteria and requires the presence of specific clinical symptoms and of demyelinating criteria on the electroneuromyogram (ENMG) or of additional supportive criteria (spinal fluid examination with dissociation between albumin level and cellular abnormalities, nervous abnormalities on MRI or other minor abnormalities on ENMG, demyelinating features on nerve biopsy or patient improvement under so-called first-line therapy with immunodulator treatment). After failure of two successive first line immunomodulating drug therapies (corticosteroids, immunomodulating immunoglobulins, or plasma exchange), several options can be considered as second line therapies. The efficacy of autologous hematopoietic cell transplantation (AHCT) has been shown in CIDP patients. The aim of these recommendations established by a working group of experts from the "Société française de greffe de moelle osseuse et thérapie cellulaire (SFGM-TC)", the group "maladies auto-immunes et thérapie cellulaire (MATHEC)" and the "filière de santé maladies rares neuromusculaire (FILNEMUS)" is to specify the eligibility criteria for AHCT in CIPD patients, to describe the mobilization and the conditioning regimen for the AHCT procedure, as well as the patient standardized post-transplant follow-up and the management of neurological treatment throughout the all procedure

Anti-CD19 CAR T-Cell Therapy for Patients with Richter Syndrome: A Lysa Study from the Descar-T Registry

International audienceBackground Richter syndrome (RS) refers to the onset of aggressive lymphoma, mostly diffuse large B-cell lymphoma (DLBCL), in patients with chronic lymphocytic leukemia (CLL). The outcome of RS patients is usually very poor with short survival (typically 2. Tocilizumab was administered to 9 (75%) patients. Five (42%) patients had ICANS, 3 (25%) with grade > 3. Regarding hematotoxicity, 6 (50%) patients presented with grade > 2 thrombocytopenia, 5 (42%) with grade > 2 anemia, and 7 with (58%) grade > 2 neutropenia. One case of macrophage activation syndrome was reported. Three patients were admitted to intensive care. A total of 5 (42%) patients had infections. After a median follow-up of 1.6 months (range, 0-23), 8 (67%) patients were alive, 4 (33%) patients died (2 from CRS and 2 from disease progression).Conclusions CD19-directed CAR T-cell therapy showed high response rates in our series of heavily pretreated RS patients. Frequency of CAR T-cell-specific adverse events was in the range of what is observed in de novo DLBCL while severity appeared higher (Schuster et al., NEJM 2019; Neelapu et al., NEJM 2017). Larger cohort with longer follow-up and prospective trials are warranted to confirm these observations
