IELSG38: phase II trial of front-line chlorambucil plus subcutaneous rituximab induction and maintenance in mucosa-associated lymphoid tissue lymphoma.

The IELSG38 trial was conducted to investigate the effects of subcutaneous (SC) rituximab on the complete remission (CR) rate and the benefits of SC rituximab maintenance in patients with extranodal marginal zone lymphoma (MZL) who received front-line treatment with chlorambucil plus rituximab. Study treatment was an induction phase with oral chlorambucil 6 mg/m2/day on weeks 1-6, 9-10, 13-14, 17-18, and 21-22, and intravenous rituximab 375 mg/m2 on day 1 of weeks 1-4, and 1,400 mg SC on weeks 9, 13, 17, and 21. Then, a maintenance phase followed with rituximab administered at 1,400 mg SC every two months for two years. Of the 112 patients enrolled, 109 were evaluated for efficacy. The CR rates increased from 52% at the end of the induction phase to 70% upon completion of the maintenance phase. With a median follow-up of 5.8 years, the 5-year event-free, progression-free, and overall survival rates were 87% (95% CI: 78-92), 84% (95% CI: 75-89), and 93% (95% CI: 86-96), respectively. The most common grade ≥3 toxicities were neutropenia (33%) and lymphocytopenia (16%). Six patients experienced treatment-related serious adverse events, including fever of unknown origin, sepsis, pneumonia, respiratory failure, severe cerebellar ataxia, and fatal acute myeloid leukemia. The trial showed that SC rituximab did not improve the CR rate at the conclusion of the induction phase, which was the main endpoint. Nevertheless, SC rituximab maintenance might have facilitated long-term disease control, potentially contributing to enhanced event-free and progression-free survival.

Experiencing the COVID-19 health crisis: Quality of life of young to mid-life hematology patients.

PURPOSE: This study questions the quality of life of young to mid-life hematology patients during lockdowns in France. METHOD: Fifteen semi-structured interviews were conducted in 2022. FINDINGS: Thematic content analysis identified three main themes: (1) regulating fear of COVID-19 during the health crisis, (2) maintaining relationships and fostering social support during the pandemic, and (3) removing the stigma of cancer with COVID-19: a positive factor for patients' quality of life. INTERPRETATION: Study participants experienced the restrictions imposed on the entire population in the face of COVID-19 in various ways, including positive events. In fact, for some, the lockdown situation allowed them to better "fit in" and feel less stigmatized because of their patient status. Indeed, lifestyles specific to them became common barrier gestures to the whole population. IMPLICATIONS FOR PSYCHOSOCIAL PROVIDERS OR POLICY: The results underline the importance of broadening the communication fields and fostering psychosocial skills in these patients.

A Comparison of 3-Year Follow-up of ZUMA-5 (Axicabtagene Ciloleucel) With SCHOLAR-5 in Relapsed/Refractory Follicular Lymphoma.

In the pivotal ZUMA-5 trial, axicabtagene ciloleucel (axi-cel; an autologous anti-CD19 chimeric antigen receptor T-cell therapy) demonstrated high rates of durable response in relapsed/refractory follicular lymphoma patients. SCHOLAR-5 is an external control cohort designed to act as a comparator to ZUMA-5. Here, we present an updated comparative analysis of ZUMA-5 and SCHOLAR-5, using the 36-month follow-up data and the intent-to-treat population of ZUMA-5. Using propensity-score methods, 127 patients in ZUMA-5 were compared to 129 patients in SCHOLAR-5. At this extended follow-up, axi-cel continues to demonstrate clinically meaningful benefits in survival compared to historically available treatments in this population.

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 < 0.001, with a decrease in relapse incidence (RI) from 49% to 38%, while non-relapse mortality (NRM) remained unchanged (4%). After allo-HSCT, 3-year-OS increased from 33% (1990-1999) to 46% (2015-2021) (p < 0.001); 3-year RI remained at 39% and 1-year-NRM decreased to 19% (p < 0.001). Our data reflect advancements over 32 years and >40,000 transplants, providing insights for evaluating emerging DLBCL therapies.

Health-related quality of life profile of newly diagnosed patients with Hodgkin and non-Hodgkin lymphomas: A real-world study including 3922 patients from the French REALYSA cohort.

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.

Lisocabtagene maraleucel in follicular lymphoma: the phase 2 TRANSCEND FL study.

An unmet need exists for patients with relapsed/refractory (R/R) follicular lymphoma (FL) and high-risk disease features, such as progression of disease within 24 months (POD24) from first-line immunochemotherapy or disease refractory to both CD20-targeting agent and alkylator (double refractory), due to no established standard of care and poor outcomes. Chimeric antigen receptor (CAR) T cell therapy is an option in R/R FL after two or more lines of prior systemic therapy, but there is no consensus on its optimal timing in the disease course of FL, and there are no data in second-line (2L) treatment of patients with high-risk features. Lisocabtagene maraleucel (liso-cel) is an autologous, CD19-directed, 4-1BB CAR T cell product. The phase 2 TRANSCEND FL study evaluated liso-cel in patients with R/R FL, including 2L patients who all had POD24 from diagnosis after treatment with anti-CD20 antibody and alkylator ≤6 months of FL diagnosis and/or met modified Groupe d'Etude des Lymphomes Folliculaires criteria. Primary/key secondary endpoints were independent review committee-assessed overall response rate (ORR)/complete response (CR) rate. At data cutoff, 130 patients had received liso-cel (median follow-up, 18.9 months). Primary/key secondary endpoints were met. In third-line or later FL (n = 101), ORR was 97% (95% confidence interval (CI): 91.6‒99.4), and CR rate was 94% (95% CI: 87.5‒97.8). In 2L FL (n = 23), ORR was 96% (95% CI: 78.1‒99.9); all responders achieved CR. Cytokine release syndrome occurred in 58% of patients (grade ≥3, 1%); neurological events occurred in 15% of patients (grade ≥3, 2%). Liso-cel demonstrated efficacy and safety in patients with R/R FL, including high-risk 2L FL. ClinicalTrials.gov identifier: NCT04245839 .

Improved outcome of COVID-19 over time in patients treated with CAR T-cell therapy: Update of the European COVID-19 multicenter study on behalf of the European Society for Blood and Marrow Transplantation (EBMT) Infectious Diseases Working Party (IDWP) and the European Hematology Association (EHA) Lymphoma Group.

COVID-19 has been associated with high mortality in patients treated with Chimeric Antigen Receptor (CAR) T-cell therapy for hematologic malignancies. Here, we investigated whether the outcome has improved over time with the primary objective of assessing COVID-19-attributable mortality in the Omicron period of 2022 compared to previous years. Data for this multicenter study were collected using the MED-A and COVID-19 report forms developed by the EBMT. One-hundred-eighty patients were included in the analysis, 39 diagnosed in 2020, 35 in 2021 and 106 in 2022. The median age was 58.9 years (min-max: 5.2-78.4). There was a successive decrease in COVID-19-related mortality over time (2020: 43.6%, 2021: 22.9%, 2022: 7.5%) and in multivariate analysis year of infection was the strongest predictor of survival (p = 0.0001). Comparing 2022 with 2020-2021, significantly fewer patients had lower respiratory symptoms (21.7% vs 37.8%, p = 0.01), needed oxygen support (25.5% vs 43.2%, p = 0.01), or were admitted to ICU (5.7% vs 33.8%, p = 0.0001). Although COVID-19-related mortality has decreased over time, CAR T-cell recipients remain at higher risk for complications than the general population. Consequently, vigilant monitoring for COVID-19 in patients undergoing B-cell-targeting CAR T-cell treatment is continuously recommended ensuring optimal prevention of infection and advanced state-of-the art treatment when needed.

A quick access to information on influenza burden and prevention in Lyon university hospital: A prospective QR code-based information campaign in 2022-2023.

BACKGROUND: Influenza vaccines are effective in decreasing hospitalizations and mortality related to influenza and its complications. However, the Vaccine Coverage Rate of influenza remains low and multifaceted efforts are required to improve it. The aim of this study was to assess the impact on influenza vaccine perception using a digital tool among outpatients and health care workers (HCWs). METHODS: A study was performed among outpatients and the HCWs of 23 hospital departments from 4 hospitals affiliated to Lyon university Hospitals (France), between October 2022 and February 2023. By scanning QR (Quick Response) codes, displayed on posters for patients, their companions, as well as in the letters sent to HCWs, users accessed anonymously to a web-application (ELEFIGHT®), which provided information on influenza and invited them to initiate a discussion on influenza prevention with their physicians during the consultation. Patients were also invited to complete a questionnaire regarding their perception of influenza vaccination before and after reading the information on ELEFIGHT®. The retention rate (RR = proportion of people who remain on the page for >2 s), the conversion rate (CR = proportion of people who click on the "Call-To-Action" button) and the absolute variation (difference in the perception before/after) and relative variation (absolute change as a percentage of the initial perception) in perception regarding influenza vaccination before and after consulting the application were calculated. RESULTS: 3791 scans were performed by 3298 patients and/or their companions with a RR of 52% and a CR of 55.1% and 253 scans by 221 HCWs with a RR of 71.2% and a CR of 115.3%. Participants spent an average of 47 s on the application. The questionnaire on influenza vaccination perception was completed by 1533 participants (46.5%); 1390 (90.7%) maintained the same position (neutral, favorable or unfavorable) on this vaccination before and after consulting the application. The relative variations in favor of vaccination were + 7.2% (unfavorable then favorable) and + 19.8% (neutral then favorable). CONCLUSION: This study suggests that a facilitated direct access to medical information through QR codes disseminated in health settings can help nudge people to foster their awareness of influenza and its prevention. Future deployments in a similar context or to other populations could be envisaged. Other vaccine-preventable and/or chronic diseases could also be the target of similar projects as part of public health programs.
