Management of MDS is largely based on risk stratification of patients into either lower-risk or higher-risk categories using the International Prognostic Scoring System-Revised and, more recently, on the Molecular International Prognostic Scoring System. Lower-risk MDS is often managed with the goal of ameliorating cytopenias and improving quality of life, while higher-risk MDS is treated with therapies aimed at extending survival and delaying progression to acute myeloid leukemia (AML). Therapeutic strategies in lower-risk MDS patients may consist of erythropoiesis stimulating agents, luspatercept, and lenalidomide for selected patients. Furthermore, imetelstat has recently been added to the FDA-approved therapeutic armamentarium for lower-risk MDS. In higher-risk MDS, monotherapy with hypomethylating agents continues to be the standard of care. While several novel hypomethylating agent combinations have and are being studied in large randomized phase 3 clinical trials, including the combination of azacitidine and venetoclax, no combination to date have improved overall survival to azacitidine monotherapy. Moreover, biomarker-directed therapies as well as immonotherapeutic approaches are currently being evaluated in early phase trials. Despite recent advancements, the lack of therapeutic agents, particularly after the failure of first line therapy in higher risk MDS, continues to be a major hurdle in the management of MDS. In this review, we discuss the current treatment landscape of MDS and provide an overview of novel agents currently in clinical development that have the potential to alter our current treatment paradigms.</div></div>","PeriodicalId":21684,"journal":{"name":"Seminars in hematology","volume":"61 6","pages":"Pages 358-369"},"PeriodicalIF":5.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142401199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Preventing infections could significantly improve both survival and quality of life. Unfortunately, both infections and antimicrobial prophylaxis in patients with MDS are incompletely assessed due to the heterogeneity of disorders included in each publication, changing definitions over time, and lack of standardized prophylaxis practices. Despite these limitations, some basic statements can be made. Infections in MDS are associated with neutropenia. Patients with lower-risk (LR) MDS tend to have fewer infections compared to patients with higher-risk (HR) MDS, which may be related to the different prevalence of neutropenia in the 2 groups. Pneumonia is the most common infection, and bacteria are the most common pathogens. Invasive fungal infections (IFI) are uncommon. Reactivation of latent viruses are rare. With the limited data available, we agree that antibacterial prophylaxis can be considered in patients with HR-MDS during severe neutropenia and early cycles of therapy when infections are most likely to occur. Given the low prevalence of IFI and viral reactivation, antimicrobial prophylaxis for these pathogens is less likely to be advantageous for most patients, although antifungal prophylaxis with activity against mold is commonly used in patients with persistent, profound neutropenia. Ultimately, improved data collection regarding infections and antimicrobial prophylaxis is needed to improve care for patients with MDS.</div></div>","PeriodicalId":21684,"journal":{"name":"Seminars in hematology","volume":"61 6","pages":"Pages 348-357"},"PeriodicalIF":5.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142093712","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several important genes contribute to disease susceptibility. This paper explores common genetic predisposition genes in MDS, including <em>DDX41, CEBPA</em>, and <em>SAMD9/SAMD9L</em>, which are linked to hereditary conditions presenting diagnostic and clinical challenges. It delves into hereditary conditions that affect platelet production and count, such as <em>RUNX1, ETV6</em>, and <em>ANKRD26</em>, detailing their clinical features and how they contribute to an increased risk of MDS. The discussion extends to additional genetic syndromes like <em>GATA2</em> deficiency, telomere biology disorders, Fanconi anemia, and Li-Fraumeni syndrome, along with new findings on genes like <em>ERG</em> that offer new insights into disease etiology. The importance of genetic counseling in MDS is underscored, outlining its goals, methods for evaluating family history, risk assessment, and the ethical considerations involved. Furthermore, the role of hematopoietic cell transplantation in managing MDS, particularly in patients with germline syndromes, is reviewed, emphasizing the need for optimal donor selection and personalized treatment approaches. This comprehensive overview illustrates the critical role of genetic factors in MDS and highlights the need for continued research and tailored clinical practices to improve patient outcomes.</div></div>","PeriodicalId":21684,"journal":{"name":"Seminars in hematology","volume":"61 6","pages":"Pages 370-378"},"PeriodicalIF":5.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142507134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
