Efficacy and safety of Glofitamab in patients with R/R DLBCL in real life setting- a retrospective study.

Glofitamab, a CD20-directed CD3 T-cell engager, was recently FDA-approved after demonstrating a 52% overall response rate (ORR) and a 39% complete response (CR) rate in heavily pretreated diffuse large B-cell lymphoma (DLBCL) patients. However, real-world data on its efficacy and safety remain limited. This study evaluated glofitamab's performance in clinical practice.

In patients with follicular lymphoma, delayed-onset neutropenia induced by anti-CD20 monoclonal antibodies frequently occurs during maintenance therapy and is preferentially associated with obinutuzumab.

The prevalence of anti-CD20 monoclonal antibody (MoAb)-associated delayed-onset neutropenia (DON) varies between 8 and 27%. Despite the wide use of MoAbs as maintenance in follicular lymphoma (FL), data regarding DON occurrence and clinical consequences are limited. This study assessed DON prevalence, severity and risk factors in FL patients during maintenance.

Preventing Severe COVID-19 with Tixagevimab-Cilgavimab in Hematological Patients Treated with Anti-CD20 Monoclonal Antibodies: An International Multicenter Study.

Introduction: Despite the declining public health emergency status, COVID-19 still poses significant risks, especially for immunocompromised individuals. We aimed to evaluate the effectiveness of tixagevimab-cilgavimab (T-C) prophylaxis in preventing severe COVID-19 in patients with hematologic malignancies (HM) treated with anti-CD20 therapy during the early Omicron variant phase of the pandemic.

Methods: The European Society of Clinical Microbiology and Infectious Diseases Study Group for Respiratory Viruses (ESGREV) conducted a multicenter retrospective cohort study involving 15 centers from 5 countries.

Novel Bispecific T-Cell Engagers for the Treatment of Relapsed B Cell Non-Hodgkin Lymphomas: Current Knowledge and Treatment Considerations.

This article provides an overview of the novel treatments focusing on the class of bispecific T cell engagers (BiTEs) for the treatment of diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL), the two most prevalent subtypes of B cell non-Hodgkin lymphomas (B-NHL). After a brief outline of these diseases, the difficulties in the management of relapsed or refractory (R/R) disease are highlighted. There are currently 4 main BiTEs showing promise in treating R/R B-NHL-glofitamab, epcoritamab, mosunetuzumab, and odronextamab.

Psychological burden and depressive symptoms in caregivers of hemato-oncological patients: the role of medical visits.

Informal caregivers of patients with cancer are known to experience extensive burdens, whereas this issue remains unresolved in the setting of hematological malignancies. Yet, these diseases are characterized by a prolonged course, numerous relapses, and implementation of multiline therapy, administered in outpatient facilities. This study aimed to assess the factors contributing to burden and depressive symptoms in informal caregivers of patients with hematological malignancies, while concentrating on the role of medical visits.

Knowledge of the Serological Response to the Third BNT162b2 Vaccination May Influence Compliance of Healthcare Workers to Booster Dose.

Background: Previous studies showed that the fourth SARS-CoV-2 vaccine dose has a protective effect against infection, as well as against severe disease and death. This study aimed to examine whether knowledge of a high-level antibody after the third dose may reduce compliance to the fourth booster dose among healthcare workers (HCWs).

Methods: We conducted a prospective cohort study among HCWs vaccinated with the first three doses at Rambam Healthcare Campus, a tertiary hospital in northern Israel.

Flow-cytometry Assessment of DNA content and Immunophenotyping of Immune-cells in Lymph-node-specimens as a Potential Diagnostic Signature of Aggressiveness in B-Non-Hodgkin Lymphomas.

Flow-cytometry (FC) is a powerful tool that can assist in lymphoma diagnosis in lymph node (LN) specimens. Although lymphoma diagnosis and classification are mainly based on tumor cell characteristics, surrounding cells are less employed in this process. We retrospectively investigated alterations in the ploidy status, proliferative cell fraction (PF) and the percentages of surrounding immune cells in 62 consecutive LN specimens with B-Cell Non-Hodgkin Lymphoma (B-NHL) that were submitted for FC evaluation between 2019-2022.

An international multicenter study comparing COVID-19 omicron outcomes in patients with hematological malignancies treated with obinutuzumab versus rituximab.

Objectives: Hematological malignancy (HM) patients treated with anti-CD20 monoclonal antibodies are at higher risk for severe COVID-19. A previous single-center study showed worse outcomes in patients treated with obinutuzumab compared to rituximab. We examined this hypothesis in a large international multicenter cohort.

A phase 2 study of ibrutinib maintenance following first-line high-dose methotrexate-based chemotherapy for elderly patients with primary central nervous system lymphoma.

Background: Elderly patients account for nearly 70% of all primary central nervous system lymphoma (PCNSL) cases. They cannot tolerate aggressive treatment and have poor prognosis with a median overall survival (OS) of less than 2 years and progression-free survival (PFS) of 6-16 months. Ibrutinib penetrates the blood-brain barrier and has shown activity in PCNSL.

Clonal Myeloid Dysplasia Following CAR T-Cell Therapy: Chicken or the Egg?

Multiple myeloma (MM) is characterized by recurrent relapses. Consequently, patients receive multiple therapy lines, including alkylating agents and immune modulators, which have been associated with secondary malignancies such as myelodysplastic syndrome (MDS). Anti-B-cell maturation antigen (BCMA) chimeric antigen receptor T cell (CART) therapy is efficacious in patients with relapsed/refractory (R/R) MM.

In chronic lymphocytic leukemia, activation of the thrombopoietin receptor promotes T-cell inhibitory properties, contributing to immunosuppression.

In chronic lymphocytic leukemia (CLL), the immune system is skewed towards a suppressive milieu. Levels of thrombopoietin (TPO), promoting cellular immune regulatory activity in immune thrombocytopenic purpura, were shown to be elevated in CLL patients. This study explored TPO as a potential immunomodulator, supporting CLL progression.

The role of additional chemotherapy prior to autologous HCT in patients with relapse/refractory DLBCL in partial remission-A retrospective multicenter study.

Objectives: To evaluate the role of additional chemotherapy before autologous hematopoietic cell transplantation (HCT) in patients with relapse/refractory diffuse large B-cell lymphoma (DLBCL) who achieve partial remission following first salvage therapy.

Methods: We conducted a multicenter retrospective study of all adult patients with DLBCL who underwent HCT between 2008 and 2020 and achieved partial response (PR) after the first salvage and were either referred directly to HCT (n = 47) or received additional salvage therapy before HCT (n = 22).

Results: Post-HCT CR rate and progression-free survival were comparable between the two groups (66% vs.

Clinical features, therapy patterns, outcomes and prognostic factors of solitary plasmacytomas: a report of the Israeli Myeloma Study Group.

Solitary plasmacytoma (SP) is a rare plasma cell dyscrasia. In this retrospective multicenter study, 68 SP patients were included. Compared to solitary extramedullary plasmacytoma (SEP), patients with solitary bone plasmacytoma (SBP) were younger (57.

Association between IgG antibody levels and adverse events after first and second Bnt162b2 mRNA vaccine doses.

Objectives: This study sought to correlate the SARS-CoV-2 IgG antibody response level to the BNT162b2 (Pfizer BioNTech) mRNA vaccine after the first and second doses with the reported adverse events.

Methods: This cohort study examined the adverse events profiles of people vaccinated with BNT162b2 in our institute between late 2020 and May 2021. Adverse events, age, and sex were reported using an electronic questionnaire, and their SARS-CoV-2 IgG antibody levels were retrieved from the hospital database.

A prediction model for central venous catheter-related thrombosis in patients with newly-diagnosed acute myeloid leukemia: A derivation cohort analysis.

Background: Catheter-related thrombosis (CRT) is a common complication in cancer patients, that may lead to chemotherapy deferral, elevated risk for systemic infections and pulmonary embolism. This study aimed to assess CRT incidence and risk factors in newly-diagnosed acute myeloid leukemia (AML) patients and create predictive models potentially allowing to decrease CRT occurrence in this population.

Methods: This retrospective single-center analysis included all AML patients treated at the Rambam Health Care Campus between 2006 and 2019.

Revisiting SARS-CoV-2 environmental contamination by patients with COVID-19: The Omicron variant does not differ from previous strains.

SARS-CoV-2 Omicron strain emergence raised concerns that its enhanced infectivity is partly due to altered spread/contamination modalities. We therefore sampled high-contact surfaces and air in close proximity to patients who were verified as infected with the Omicron strain, using identical protocols applied to sample patients positive to the original or Alpha strains. Cumulatively, for all 3 strains, viral RNA was detected in 90 of 168 surfaces and 6 of 49 air samples (mean cycle threshold [Ct]=35.

A Phase II Study to Assess the Safety and Efficacy of the Dual mTORC1/2 and PI3K Inhibitor Bimiralisib (PQR309) in Relapsed, Refractory Lymphoma.

Bimiralisib is an orally bioavailable pan-phosphatidylinositol 3-kinase and mammalian target of rapamycin inhibitor which has shown activity against lymphoma in preclinical models. This phase I/II study evaluated the response rate to bimiralisib at 2 continuous dose levels (60 mg and 80 mg) in patients with relapsed/refractory lymphoma. Fifty patients were enrolled and started treatment.

Dose-adjusted EPOCH-R is not superior to sequential R-CHOP/R-ICE as a frontline treatment for newly diagnosed primary mediastinal B-cell lymphoma: Results of a bi-center retrospective study.

Purpose: Primary mediastinal B-cell lymphoma (PMBCL) is a rare subtype of diffuse large B-cell lymphoma (DLBCL). Despite its aggressive course, PMBCL is considered curable. While in recent years dose-adjusted (DA) EPOCH-R (rituximab, etoposide, prednisone, vincristine, cyclophosphamide and doxorubicin) has become widely endorsed as first-line therapy for newly-diagnosed PMBCL, the optimal treatment for this disease and the role of radiotherapy (RT) remains unclear.
