Antiapoptotic Bcl-2 family proteins are involved in myeloma cell survival. To date, their expression in multiple myeloma (MM) patients has mostly been analyzed at the RNA level. In the present study, we quantified for the first time the protein expression of the Bcl2-family members using a capillary electrophoresis immunoassay in 120 newly diagnosed MM patients, aged ≤65 years, treated in the context of the PETHEMA/GEM2012 study.

Chimeric antigen receptor (CAR) T-cell therapy has emerged as a transformative treatment for aggressive B-cell lymphomas (ABCL), However, about half of patients relapse, most of them early. This study investigates the detection of CAR copies in circulating cell-free DNA (cfDNA) as a potential predictive biomarker of early relapse (<6 months) to improve patient management. In this research, we have consecutively selected 73 ABCL patients treated with anti-CD19 CAR T-cells, analysing CAR levels in peripheral blood and other clinical variables.

Asymptomatic IgM gammopathy encompasses IgM monoclonal gammopathy of undetermined significance (MGUS) and asymptomatic Waldenström macroglobulinemia (AWM), both having a risk of progression to symptomatic disease. Here, we assessed the risk of progression and the mortality of 956 patients with asymptomatic IgM gammopathy across 25 Spanish centers. After a median follow-up of 5.

Haploidentical haematopoietic stem cell transplantation (haplo-HSCT) is one of the most effective therapies for treating malignant haematological disorders. However, HLA disparities are significant barriers to the success of this process since they increase the risk of graft versus host disease (GvHD). HLA disparities quantification could help to anticipate the probability and degree of GvHD, but the best tool for such quantification remains a challenge.

The pathogenesis of COVID-19 warrants unravelling. Genetic polymorphism analysis may help answer the variability in disease outcome. To determine the role of KIR and HLA polymorphisms in susceptibility, progression, and severity of SARS-CoV-2 infection, 458 patients and 667 controls enrolled in this retrospective observational study from April to December 2020.

Article Synopsis
  • The ASPEN study is a Phase III clinical trial that compares the effectiveness of two drugs, zanubrutinib and ibrutinib, in treating patients with Waldenström macroglobulinemia (WM).
  • A total of 201 patients participated, with 102 receiving zanubrutinib and 99 receiving ibrutinib, and the outcomes were evaluated using patient-reported questionnaires.
  • Results indicated that zanubrutinib led to better improvements in health-related quality of life, particularly regarding symptoms like diarrhea and nausea/vomiting, as well as overall physical functioning and fatigue in patients who achieved a very good partial response to treatment.

The value of quantitative immunoprecipitation mass spectrometry (QIP-MS) to identify the M-protein is being investigated in patients with monoclonal gammopathies but no data are yet available in high-risk smoldering myeloma (HRsMM). We have, therefore, investigated QIP-MS to monitor peripheral residual disease (PRD) in 62 HRsMM patients enrolled in the GEM-CESAR trial. After 24 cycles of maintenance, detecting the M-protein by MS or clonal plasma cells by next-generation flow cytometry (NGF) identified cases with a significantly shorter median progression-free survival (mPFS) (MS: not reached vs.

Circulating tumour DNA (ctDNA) allows genotyping and minimal residual disease (MRD) detection in lymphomas. Using a next-generation sequencing (NGS) approach (EuroClonality-NDC), we evaluated the clinical and prognostic value of ctDNA in a series of R-CHOP-treated diffuse large B-cell lymphoma (DLBCL) patients at baseline (n = 68) and after two cycles (n = 59), monitored by metabolic imaging (positron emission tomography combined with computed tomography [PET/CT]). A molecular marker was identified in 61/68 (90%) ctDNA samples at diagnosis.

The efficacies of chimeric antigen receptor T cells (CAR-Ts) and bispecific monoclonal antibodies (BiAbs) for triple-class refractory (TCR) myeloma have not previously been compared, and clinical data on how to rescue patients after relapse from these immunotherapies are limited. A retrospective study of 73 TCR patients included in trials was conducted: 36 received CAR-Ts and 37 received BiAbs. CAR-Ts produced a higher overall response rate (ORR) than BiAbs (97.

Smoldering multiple myeloma (SMM) precedes multiple myeloma (MM). The risk of progression of SMM patients is not uniform, thus different progression-risk models have been developed, although they are mainly based on clinical parameters. Recently, genomic predictors of progression have been defined for untreated SMM.

Several single-arm studies have explored the inclusion of brentuximab vedotin (BV) in salvage chemotherapy followed by autologous stem cell transplantation (ASCT) for relapsed/refractory (R/R) classical Hodgkin lymphoma (cHL). However, no head-to-head comparisons with standard salvage chemotherapy have been performed. This study presents a propensity score-matched analysis encompassing individual patient data from 10 clinical trials to evaluate the impact of BV in transplant-eligible patients with R/R cHL.

Article Synopsis
  • The phase 3 ASPEN trial compared the effectiveness of two BTK inhibitors, zanubrutinib and ibrutinib, in treating Waldenström macroglobulinemia, analyzing genetic mutations' impact on treatment response.
  • The study found that patients with mutations in CXCR4 and TP53 had poorer responses and survival rates but those treated with zanubrutinib generally showed better outcomes than those given ibrutinib.
  • Overall, the research indicated that zanubrutinib offers improved clinical outcomes for patients with specific mutations compared to ibrutinib, highlighting the importance of genetic testing in treatment decision-making.

Single-cell DNA sequencing can address the sequence of somatic genetic events during myeloid transformation in relapsed acute myeloid leukemia (AML). We present an -mutated AML patient with an initial low ratio of -ITD (low-risk ELN-2017), treated with midostaurin combined with standard chemotherapy as front-line treatment, and with salvage therapy plus gilteritinib following allogenic stem cell transplantation after relapse. Simultaneous single-cell DNA sequencing and cell-surface immunophenotyping was used in diagnostic and relapse samples to understand the clinical scenario of this patient and to reconstruct the clonal composition of both tumors.

Patients affected by multiple myeloma (MM) have an increased risk of severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) infection and subsequent coronavirus (20)19 disease (COVID-19)-related death. The changing epidemiological and therapeutic scenarios suggest that there has been an improvement in severity and survival of COVID-19 during the different waves of the pandemic in the general population, but this has not been investigated yet in MM patients. Here we analyzed a large cohort of 1221 patients with MM and confirmed SARS-CoV-2 infection observed between February 2020, and August 2022, in the EPICOVIDEHA registry from 132 centers around the world.

Article Synopsis
  • - Waldenström's macroglobulinemia (WM) is characterized as a type of lymphoma involving IgM monoclonal gammopathy and requires evidence of lymphoplasmacytic leukemia in the bone marrow for diagnosis.
  • - Immunophenotyping and genotyping are crucial for accurately diagnosing WM and distinguishing it from similar diseases like marginal zone lymphoma and multiple myeloma.
  • - The text emphasizes the need for standardized methodologies in mutational analysis for WM diagnosis and suggests exploring the diagnostic value of certain gene mutations that are not routinely assessed.

Objectives: Elderly patients with hematologic malignancies face the highest risk of severe COVID-19 outcomes. The infection's impact on different age groups remains unstudied in detail.

Methods: We analyzed elderly patients (age groups: 65-70, 71-75, 76-80, and >80 years old) with hematologic malignancies included in the EPICOVIDEHA registry between January 2020 and July 2022.

Responses to treatment have improved over the last decades for patients with multiple myeloma. This is a consequence of the introduction of new drugs that have been successfully combined in different clinical contexts: newly diagnosed, transplant-eligible or ineligible patients, as well as in the relapsed/refractory setting. However, a great proportion of patients continue to relapse, even those achieving complete response, which underlines the need for updated response criteria.
