Introduction: Enteropathy-associated T-cell lymphoma (EATL) is a peripheral T-cell lymphoma (PTCL) with a poor prognosis. Cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without etoposide consolidated by autologous stem cell transplantation (ASCT) are recommended for fit PTCL patients. The role of etoposide and ASCT in EATL is unclear.

Background: Peripheral T-cell lymphomas are aggressive non-Hodgkin lymphomas with few treatment options for relapsed or refractory disease. Valemetostat tosylate (valemetostat) is a potent, novel, dual inhibitor of EZH2 and EZH1. We investigated the clinical activity and safety of valemetostat in patients with relapsed or refractory peripheral T-cell lymphoma, and its safety in patients with relapsed or refractory adult T-cell leukaemia/lymphoma.

Patients with high-grade B-cell lymphoma with MYC and BCL2 rearrangements (HGBL-MYC/BCL2) respond poorly to immunochemotherapy compared with patients with diffuse large B-cell lymphoma not otherwise specified (DLBCL NOS) without a MYC rearrangement. This suggests a negative impact of lymphoma-intrinsic MYC on the immune system. To investigate this, we compared circulating T cells and natural killer (NK) cells of patients with HGBL-MYC/BCL2 (n = 66), patients with DLBCL NOS (n = 53), and age-matched healthy donors (HDs; n = 16) by flow cytometry and performed proliferation, cytokine production, and cytotoxicity assays.

Background: Studies on the efficacy of rituximab in primary CNS lymphoma (PCNSL) reported conflicting results. Our international randomized phase 3 study showed that the addition of rituximab to high-dose methotrexate, BCNU, teniposide, and prednisolone (MBVP) in PCNSL was not efficacious in the short term. Here we present long-term results after a median follow-up of 82.

Article Synopsis
  • - Cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS) can negatively affect the effectiveness of CAR T-cell therapy in patients with relapsed/refractory large B-cell lymphoma (r/r LBCL).
  • - The study evaluated various EASIX scoring systems to predict the risk of ICANS in 154 patients receiving CAR T-cell therapy, with certain scores showing a moderate ability to identify patients at risk for ICANS grade ≥ 2.
  • - Although the (m-/s-) EASIX scores can help assess risk for ICANS, their moderate predictive performance suggests the need for further refinement before they can be reliably used in clinical settings for directing patient care. *

Peripheral T-cell lymphomas (PTCL) comprise a heterogeneous group of mature T-cell neoplasms with an unfavorable prognosis; presentation with stage I(E) disease is uncommon. In clinical practice, an abbreviated chemotherapy treatment regimen combined with radiotherapy (combined modality treatment [CMT]) is commonly used, although evidence from clinical trials is lacking. The aim of this nationwide population-based cohort study is to describe first-line treatment and outcome of patients with stage I(E) PTCL.

Treatment choice according to the individual conditions remains challenging, particularly in older patients with acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (MDS). The impact of performance status, comorbidities, and physical functioning on survival is not well defined for patients treated with hypomethylating agents. Here we describe the impact of performance status (14% ECOG performance status 2), comorbidity (40% HCT-comorbidity index ≥ 2), and physical functioning (41% short physical performance battery < 9 and 17% ADL index < 6) on overall survival (OS) in 115 older patients (age ≥ 66 years) treated on a clinical trial with a 10-day decitabine schedule.

Article Synopsis
  • Researchers created a prognostic model to predict outcomes for patients with myelofibrosis undergoing allogeneic hematopoietic cell transplantation by analyzing data from 623 patients in the U.S. (CIBMTR cohort) from 2000 to 2016.
  • They identified key factors that influence mortality, assigning weighted scores based on age, donor matching, hemoglobin levels, and donor compatibility, which resulted in differing survival rates among low, intermediate, and high score groupings.
  • The model was validated in a European cohort (EBMT), proving effective for predicting overall survival and transplant-related mortality, aiding clinicians in discussing transplantation prospects with myelofibrosis patients.

Allogeneic hematopoietic cell transplantation (allo-HCT) remains the only curative treatment for myelofibrosis. However, the optimal conditioning regimen either with reduced-intensity conditioning (RIC) or myeloablative conditioning (MAC) is not well known. Using the Center for International Blood and Marrow Transplant Research database, we identified adults aged ≥18 years with myelofibrosis undergoing allo-HCT between 2008-2019 and analyzed the outcomes separately in the RIC and MAC cohorts based on the conditioning regimens used.

Purpose: Prompt recognition of acute chimeric antigen receptor T (CAR T)-cell-mediated toxicities is crucial because adequate and timely management can prevent or reverse potential life-threatening complications. In the outpatient setting, patients and informal caregivers have to recognize and report signs and symptoms marking these acute toxicities. This study provides a core set of patient- and caregiver-reported signs and symptoms (outcomes, P/CROs) and definitions of red flags warranting immediate action to include in a daily checklist for support at home, with the goal to make outpatient post-CAR T-cell care safer, optimize patient and caregiver support, and thereby facilitating an early discharge/hospital visit reduction strategy.
