Summary: Thrombotic events are common in patients with MM, SM, and MGUS. Platelet hyperactivation is prevalent in both MGUS and SM/MM patients, potentially related to hyporesponsiveness. Further investigation of the predictive and prognostic value of platelet hyperactivation in such patients is warranted.

Summary: Monoclonal gammopathy of undetermined significance (MGUS), a precursor to multiple myeloma, is present in over 5% of adults aged 70 and older. Our study examined patterns of multimorbidity among MGUS patients and found higher prevalence of certain comorbidities among MGUS cases, indicating the need for additional investigation.

Summary: This study compares the transcriptomes of MGUS and MM, finding specific genes and pathways involved in MGUS and new signaling pathways and gene activity in MM. Certain upregulated genes in MM may play a crucial role in the progression from benignity to malignancy and could serve as drug targets or novel biomarkers for risk of progression. Overall, these findings are important for further understanding the etiology of MGUS and MM.

Summary: Treatment with novel triplet regimens such as KRd and lenalidomide maintenance therapy for high-risk smoldering myeloma may significantly delay the progression to symptomatic multiple myeloma, altering the natural history of the disease. Further randomized clinical trials are needed to confirm the favorable benefit-to-risk profile observed in this phase 2 trial.

Summary: This study found that early treatment with EloLenDex is safe and effective for high-risk SMM patients, and provides a comprehensive characterization of alterations in immune cell composition and TCR repertoire diversity in patients. The study also revealed that the similarity of a patient's immune cell composition to that of healthy donors may have prognostic relevance at diagnosis and after treatment.

Summary: The relationship between Monoclonal Gammopathy of undetermined significance (MGUS) and Multiple Myeloma (MM) was explored using bioinformatics methods. A total of 227 genes associated with both MGUS and MM were identified, including core genes such as TNF, IL-1B, IL-6, CSF2, CXCL8, and IL-10. Eight candidate drugs were selected as potential interventions to prevent the progression from MGUS to MM.

Summary: This clinical practice guideline focuses on the care modalities that can be offered in addition to systemic antineoplastic therapy for multiple myeloma. It recommends using the International Staging System (ISS) for staging MM, using whole-body computed tomography to determine the extent of skeletal involvement in symptomatic cases, and considering biological age in treatment decision-making. For suitable patients, initial treatment with high-dose therapy and combination therapies for relapse can achieve longer progression-free survival.

Summary: This study demonstrated that patients with MGUS and MM exhibit hypercoagulability with increased thrombin generation, possibly due to higher TF and procoagulant phospholipids activity. MM patients also showed elevated levels of cf-DNA, indicating a potential association with procoagulant NETs activity.

Summary: By using mass cytometry analysis, we characterized the plasma cells and B cell lymphopoiesis in bone marrow samples from patients with different stages of multiple myeloma (MM), revealing various heterogeneities. We found overexpression of MMSET, Notch-1, and CD47 in malignant plasmablasts and plasma cells, and variations in the upregulation of B cell signaling regulators and aberrant markers were associated with different clinical outcomes. Furthermore, we identified elevated levels of various markers from hematopoietic stem cells to plasma cells, with variably modulated expression of B cell development regulators and stemness-controlling regulators. This study highlights the importance of precise molecular profiling in MM using CyTOF technology to understand disease heterogeneity and predict prognosis.

Summary: A study found that 75% of patients treated with Belantamab mafodotin (BLMF) for advanced multiple myeloma experienced ocular toxicity, with 69% developing keratopathy. Among patients who had to permanently discontinue or reduce BLMF treatment due to ocular toxicity, 70% experienced progression of multiple myeloma within 3 months.

Summary: This article reviews the progress of flow cytometry (FCM) in the diagnosis of myelodysplastic syndrome (MDS) in recent years, and provides optimal methods and recommendations for sample processing, antibody panels and fluorochromes, and current hardware technologies. These recommendations will facilitate the appropriate application of FCM assays in the diagnostic workup of MDS patients, but further standardization and harmonization are needed.

Summary: This study reveals the hallmark of a distinct subset of chronic lymphoproliferative disorder of natural killer cells (CLPD-NK) through somatic mutations in the chemokine gene CCL22. These mutations result in biased signaling downstream of the chemokine receptor, leading to increased cell chemotaxis and NK cell proliferation through interactions with the hematopoietic microenvironment.

Summary: This study provides an in-depth analysis of myeloid neoplasia caused by haploinsufficiency resulting from deletion of the long arm of chromosome 5 (del(5q)). The research identifies the importance of del(5q) genes in the development of the disease and establishes a gene signature that distinguishes del(5q) cases from diploid cases. The study also reveals the heterogeneity of gene expression within del(5q) patients and uncovers the balance of specific genes that drive clonal expansion.

Summary: This study evaluated the use of pre-defined flow cytometric markers in the diagnosis of MDS and CMML. The results showed that flow cytometry had a high concordance with the diagnosis of MDS, and could identify cases "in agreement with MDS". Furthermore, the study suggested that a 3% cut-off for myeloid progenitor cells in flow cytometry was more appropriate than the cytomorphologically defined cut-off of 5%.
