{"title":"Asciminib for Philadelphia chromosome positive leukemias.","authors":"Timothy P Hughes,Deborah L White,David T Yeung","doi":"10.3324/haematol.2024.286798","DOIUrl":"https://doi.org/10.3324/haematol.2024.286798","url":null,"abstract":"Twenty-five years after the introduction of imatinib, we have entered a new era of therapy for Chronic Myeloid Leukemia (CML). Despite the development of second and third generation (2G and 3G) tyrosine kinase inhibitors (TKIs), their impact have been incremental in improving outcomes for CML patients. While frontline use of 2G TKIs have improved molecular response rates and reduced progression to blast phase, there has been no improvement in overall survival compared to imatinib, likely due to the higher toxicity and consequent higher non CML-related mortality. Imatinib remains the most prescribed therapy for CML worldwide, despite it being the least potent TKI and most prone to resistance and progression. Asciminib, the first STAMP (Specifically Targeting the ABL Myristoyl Pocket) inhibitor, binds to the myristoyl pocket of BCR::ABL1. Its specificity minimises off-target toxicity which enables asciminib to finally break this frustrating link between potency and toxicity. After a decade of clinical trials, both in patients with resistance and intolerance to two or more TKIs, and more recently in the frontline setting, asciminib is fulfilling its early promise of a more rapid and reliable pathway to long-term disease control with minimal toxicity. There are however some unexpected challenges when using asciminib that require further investigation. In this Spotlight we review the key studies and outline the potential impact and current limitations of this first STAMP inhibitor in the CML setting and in other leukemias where ABL1 or ABL2 is the key target.","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":"21 1","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488148","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}

Systematic assessment of extracranial internal carotid artery (eICA) since June-2011 revealed that SCI-risk is associated with chronic or acute anemia and eICA-stenosis. Based on these results, SCA-children with eICA-TAMMV≥200cm/s or eICA-stenosis were placed on chronictransfusion and considered for allogeneic stem-cell transplantation (alloSCT). SCA-children with 160-199cm/s eICA-TAMMV were maintained on hydroxyurea. We hypothesized that detection/management of eICA-arteriopathy and wider use of hydroxyurea could reduce SCI-incidence. Comparison between the new cohort (May-2007/Dec-2014) eICA-assessed before age 4 with wider but not systematic use of hydroxyurea and the earlier cohort (1988/Apr-2007) never eICAassessed until the 2008 update, revealed a significant reduction of SCI-risk (Log-Rank, P=.009) associated with eICA-assessment but not with wider use of hydroxyurea. eICA-TAMMVs≥160cm/s, even with no eICA-stenosis, were risk-factors for SCI, suggesting that all SCA-children with eICATAMMV≥ 160cm/s should be placed on chronic-transfusion. Hydroxyurea initiation at an early age was associated with lower intracranial-arteriopathy incidence, but not with lower eICA-arteriopathy and SCI-incidence. In the overall cohort (1988-2014), including 332 SCA-children, all assessed/managed for eICA-arteriopathy after 2011, the cumulative-SCI-incidence by age 14 was 25.0% (95%CI:19.0%-31.0%). SCI-risk was associated with being older at first-neck-MRA and having high MCV on hydroxyurea. While the impact of hydroxyurea on SCI-incidence remains unclear, making controlled trials necessary, eICA-arteriopathy management by intensive therapy is effective at improving SCIprevention.","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":"17 1","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488157","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}

{"title":"Germline and somatic genetic landscape of pediatric myelodysplastic syndromes.","authors":"Lili Kotmayer,Alyssa L Kennedy,Marcin W Wlodarski","doi":"10.3324/haematol.2024.285700","DOIUrl":"https://doi.org/10.3324/haematol.2024.285700","url":null,"abstract":"Pediatric myelodysplastic syndromes (MDS) represent a rare group of clonal hematopoietic stem cell disorders accounting for ~5% of pediatric hematological malignancies. They are characterized by ineffective hematopoiesis, cytopenia, and dysplastic changes in the bone marrow with variable risk of progression to acute myeloid leukemia. Unlike adult MDS, pediatric cases predominantly present with hypocellular bone marrow, with monosomy 7 and trisomy 8 as the most common cytogenetic aberrations. Pediatric MDS can manifest as primary disease or arise secondary to classical inherited bone marrow failure syndromes, prior cytotoxic therapy, or acquired aplastic anemia. In recent years, new germline syndromes have been identified in a substantial proportion of patients with \"primary\" MDS. The most common are GATA2 deficiency and SAMD9/SAMD9L syndromes, accounting for at least 7% and 8%, respectively. The somatic mutational landscape is different from adult MDS, with recurrent mutations affecting SETBP1, ASXL1, RUNX1, and RAS pathway genes (PTPN11, NRAS, KRAS, CBL), while mutations in spliceosome components and epigenetic regulators which are common in adults, are virtually absent in children. Monosomy 7 serves as a \"central hub\" in disease evolution, associating with somatic leukemia driver mutations. On the other hand, somatic UBTF-TD and NPM1 mutations define a subtype of MDS with excess blasts with predominantly normal karyotype without known germline predisposition. Hematopoietic stem cell transplantation is the only curative option for pediatric MDS. Understanding the unique genetic profile of pediatric MDS has implications for diagnosis, therapy, donor selection and longterm surveillance, particularly for patients with germline predisposition syndromes. This review discusses current classification systems (WHO and ICC), provides a detailed overview of the germline and somatic genetic landscape of pediatric MDS, and highlights clinical implications of these genetic alterations.","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":"243 1","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488210","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}

The bone marrow microenvironment, particularly myeloma associated macrophages (MΦs) is critical to the progression of MM. However, there is limited understanding on the role of MΦs in DNA repair in MM. Here, we found that MΦs regulated DNA repair in MM cells by the CXCL5/8-CXCR2 axis. By promoting non-homologous end joining rather than homology-directed repair, MΦs increased the probability of chromosomal translocations in MM cells. Furthermore, clinical data confirmed that MΦs are closely associated to the increased genetic variations of MM patients' primary cells. The study elucidates a mechanism by which MΦs regulates DNA repair in MM in the microenvironment and provides a potentially new target to counter MM progression.","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":"13 1","pages":""},"PeriodicalIF":10.1,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144488153","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}
