The Revised International Prognostic Scoring System (IPSS-R), based on clinical and pathologic characteristics, has long been the standard risk stratification system used in clinical trials and practice [3]. Recent efforts have integrated genomic data within the Molecular International Prognostic Scoring System (IPSS-M) [4]. Compared to the IPSS-R, the IPSS-M results in a change in risk category in a significant number of patients, with major clinical implications. Indeed, the classification of a patient as either higher risk (HR) or lower risk (LR) is fundamental in the management of MDS, with widely differing treatment approaches. In this study, we evaluated a large cohort of patients with MDS and compared the characteristics and clinical behavior of patients who experienced a change in overall risk (HR versus LR) when re-stratified from IPSS-R to IPSS-M.</p>","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"34 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2025-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144995492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is essential to elucidate the mechanisms of resistance and develop novel treatment strategies. Histone deacetylases (HDACs) are often dysregulated in hematological malignancies, and many HDAC inhibitors have shown potent antitumor activities. In this study, we found that HDAC8 was highly expressed in Ph<sup>+</sup> B-ALL patient samples upon TKI treatment. HDAC8 inhibition significantly increased TKI-mediated elimination of leukemia cells and decreased their ability to initiate leukemia. Using two mouse models, we demonstrated that TKIs in combination with targeting HDAC8 effectively inhibited leukemia progression and reduced the frequencies of stem cells. Mechanistically, HDAC8 deacetylated hypoxia inducible factor-1α (HIF-1α) at lysine 19/21, leading to a reduction in PHD2-mediated hydroxylation and subsequent pVHL-mediated ubiquitination, which slowed the degradation of HIF-1α. HIF-1α inhibition induced apoptosis and decreased the initiating capacity of leukemia cells. Importantly, in a Ph<sup>+</sup> B-ALL patient–derived xenograft model, targeting HDAC8 or HIF-1α in combination with TKIs significantly inhibited leukemia progression.

Reflecting from this historical lens, we have seen remarkable advances in diagnostics, prognostication, and therapeutics over the decades. Concerted efforts from various consensus groups have paved the way for these advances. Herein, we perform a historical analysis of the evolution of the nosology of myeloid neoplasms over the past 50 years, beginning with the landmark 1976 FAB classification. We discuss how the new nosology of myeloid neoplasms has been inspired by the widespread availability of next-generation sequencing technology as a critical adjunct to classical morphological assessment. We discuss evidence in support of a conceptual framework for categorizing myeloid neoplasms based on ontogeny, beginning from clonal hematopoiesis of indeterminate potential (CHIP). We review the foundational definitions of CHIP, including parallels with Darwinism at the cellular level, and the relevance of incorporation of precursor conditions into the most recent disease classification of myeloid neoplasms. We shed light onto patient-focused practical implications of classification schema, with emphasis on mutation-adapted therapeutic strategies.

Four-hundred-twenty-seven former AML patients participated (response rate, 63%) ≥5 years[y] and up to 18.6 y past their leukemia diagnosis (median, 11.3 y). Median age at study participation was 61 y (range 28y–93y), 23% had experienced disease relapse, and 63% had received allogeneic hematopoietic stem cell transplantation (alloHSCT). Overall, quality of life (QoL) and general life satisfaction (gLS) summary scores were higher in AML LTS (<i>p</i> &lt; 0.001) compared to age-/sex-matched reference cohorts, although differences were small and likely not clinically relevant. However, we identified subgroups of survivors reporting impaired QoL (27%), gLS (13%) and health-related life satisfaction (hrLS; 17%). Using multivariable regression models, we identified predisposing and protective factors for each of these outcomes. Treatment with alloHSCT did not adversely impact QoL, gLS, or hrLS. In summary, global QoL and LS in AML LTS are comparable to the general population, irrespective of treatment modality, although some survivors report clinically significant impairment of global QoL and/or in specific domains. We identified factors associated with impaired outcomes (e.g., comorbidity and fatigue), delineating a subgroup of survivors with unmet needs ≥5 y after their AML diagnosis.</p>","PeriodicalId":18109,"journal":{"name":"Leukemia","volume":"13 1","pages":""},"PeriodicalIF":11.4,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144899200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
