The risk of T cell malignancies after chimeric antigen receptor (CAR) T cell therapy is a concern, although the true incidence remains unclear. Here we analyzed the DESCAR-T registry database, encompassing all pediatric and adult patients with hematologic malignancies who received CAR T cell therapy in France since 1 July 2018. Of the 3,066 patients included (2,536 B cell lymphoma, 162 B cell acute lymphoblastic leukemia (ALL) and 368 multiple myeloma), 1,680 (54.

Cancer immunotherapy, including immune checkpoint inhibitors, chimeric antigen receptor T-cell therapy and bispecific antibodies, has led to major improvements in the treatment of a wide range of hematologic malignancies and solid tumors. However, age-mediated immune system modifications, known as immunosenescence, may preclude its efficacy in elderly patients. In this review, we assessed the efficacy of these different cancer immunotherapies in elderly patients compared to young patients to revisit the concept of immunosenescence from a therapeutic perspective.

Neurodegenerative dementias have a profound impact on higher-order cognitive and behavioural functions. Investigating macroscale functional networks through cortical gradients provides valuable insights into the neurodegenerative dementia process and overall brain function. This approach allows for the exploration of unimodal-multimodal differentiation and the intricate interplay between functional brain networks.

Background And Purpose: Frontotemporal dementia (FTD) is a neurodegenerative disorder characterized by pervasive personality and behavioural disturbances with severe impact on patients and caregivers. In current clinical practice, treatment is based on nonpharmacological and pharmacological approaches. Unfortunately, trial-based evidence supporting symptomatic pharmacological treatment for the behavioural disturbances in FTD is scarce despite the significant burden this poses on the patients and caregivers.

I-FP-CIT SPECT enables the detection of presynaptic dopaminergic denervation. It allows to differentiate degenerative parkinsonian syndromes from secondary parkinsonian syndromes or essential tremor, and patients with suspected dementia with Lewy bodies from those with other dementia subtypes. The aim of our study was to evaluate the appropriateness of I-FP-CIT SPECT prescriptions, identify prescriber profiles and analyze changes in prescriptions over a decade in the Neurology department of Avicenne University hospital.

Article Synopsis
  • Plastic pollution is widespread, even in agricultural soils that receive urban compost, posing risks to the environment and health.
  • This study aimed to explore how coarse microplastics accumulate in soil over time when using different types of urban compost, analyzing samples from a 21-year experiment.
  • Results showed that the compost type influenced the amount of microplastics in the soil, revealing that while the number of particles was consistent with estimates, the mass measurements varied, potentially due to processes like biological transport or physical breakdown.

Background: Results of conventional induction chemotherapies in primary central nervous system lymphoma (PCNSL) need to be improved. Ibrutinib, a BTK inhibitor, and lenalidomide, an immunomodulatory drug, have shown promising results at relapse, supporting to further assess their individual use in combination with high-dose methotrexate-based chemotherapy.

Methods: Patients with newly diagnosed PCNSL were randomized to receive four 28-day cycles of ibrutinib or lenalidomide in combination with R-MPV (rituximab, methotrexate, procarbazine, vincristine and prednisone) in a 3 + 3 design.

Article Synopsis
  • Sleep-disordered breathing (SDB) is common in multiple system atrophy (MSA) patients, and the research evaluated the immediate effects and safety of CPAP therapy for treating SDB.
  • In a study of 63 MSA patients, CPAP therapy showed significant improvements such as normalization of apnea-hypopnea index, reduced arousal index, and increased REM sleep, with most patients tolerating the treatment well.
  • Nonresponders to CPAP therapy tended to have more severe motor symptoms, indicating that the therapy is effective primarily in milder cases of motor impairment in MSA patients.

JCO Primary analysis of the phase III randomized AATT study showed that younger patients with peripheral T-cell lymphoma (PTCL) consolidated with autologous or allogeneic transplantation (alloSCT) had similar event-free survival (EFS) and overall survival (OS). Seven-year EFS of patients randomly assigned to alloSCT was 38% (95% CI, 25 to 52) compared with 34% (95% CI, 22 to 47) for patients randomly assigned to autologous transplantation of hematopoietic stem cells (autoSCT); OS was 55% (95% CI, 41 to 69) and 61% (95% CI, 47 to 74). Among patients undergoing alloSCT (n = 26) or autoSCT (n = 41) on study, the cumulative progression/relapse rate was 8% (95% CI, 0 to 19) and 55% (95% CI, 35 to 74).

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.

Engineered cellular therapy with CD19-targeting chimeric antigen receptor T cells (CAR-Ts) has revolutionized outcomes for patients with relapsed/refractory large B-cell lymphoma (LBCL), but the cellular and molecular features associated with response remain largely unresolved. We analyzed serial peripheral blood samples ranging from the day of apheresis (day -28/baseline) to 28 days after CAR-T infusion from 50 patients with LBCL treated with axicabtagene ciloleucel by integrating single-cell RNA and T-cell receptor sequencing, flow cytometry, and mass cytometry to characterize features associated with response to CAR-T. Pretreatment patient characteristics associated with response included the presence of B cells and increased absolute lymphocyte count to absolute monocyte count ratio (ALC/AMC).

  • MRD monitoring is essential for managing blood cancers, and while traditional methods use specific molecular targets, new research identifies additional fusion transcripts as potential markers for MRD.
  • A study compared a focused RNA-seq method (FusionPlex) with a comprehensive RNA-seq approach (Advanta RNA-Seq XT) and found both methods had 100% agreement in detecting known fusions and good correlation in gene expression levels.
  • In a trial with 126 patients, the targeted RNA-seq identified fusion transcripts in nearly half of the cases, leading to the development of specialized digital PCR tests for rare fusions, suggesting a potential shift in MRD evaluation techniques.

Article Synopsis
  • Autologous anti-CD19 CAR T cells are becoming standard treatment for relapsed/refractory large B-cell lymphoma, but serious side effects like cytokine release syndrome (CRS) and neurotoxicity (ICANS) pose risks, often requiring ICU care.
  • In a study involving 925 patients in France, high rates of CRS (84.1%) and ICANS (40.5%) were observed, with significant proportions experiencing severe forms of these conditions.
  • Two prognostic scoring systems (CRS-PSS and ICANS-PSS) were developed to identify patients at higher risk for severe CRS and ICANS based on specific clinical factors, and these scores were validated in other patient groups treated with similar therapies.
