All-trans retinoic acid (ATRA) has demonstrated promising efficacy in unfit patients with acute myeloid leukemia. This multicenter controlled trial randomized (1:1) untreated patients with MDS with excess blasts (MDSEB) to ATRA plus decitabine (ATRA at 25 mg/m2/day in 2 divided daily doses throughout the 28-day cycle plus decitabine at 20 mg/m2 on days 1-5) or decitabine alone (20 mg/m2 on days 1-5). The primary endpoint was the overall response rate within four treatment cycles. A total of 227 patients were randomized. Four patients who did not commence therapy were excluded from the modified intention-to-treat (mITT) analysis. The median patient age was 62 years (range, 19-81). The overall response rate was 78% (86/110) in the ATRA group versus 51% (58/113) in the decitabine group (odds ratio =3.40; 95% confidence interval [CI]: 1.90-6.09; P<0.001). The ATRA group also had a higher complete remission rate (23% vs. 12%; odds ratio =2.05; 95% CI: 1.02-4.25; P=0.042). With a median follow-up of 30.1 months, progression-free survival (PFS) was 14.9 months in the ATRA group versus 10.5 months in the decitabine group (hazard ratio [HR]=0.70; 95% CI: 0.51-0.97; P=0.03). The overall survival was 23.0 months and 19.3 months, respectively (HR=0.77; 95% CI: 0.54-1.09; P=0.137). The two groups did not differ in grade 3 or higher hematological adverse events. In conclusion, adding ATRA to decitabine increased the overall response rate and prolonged PFS in adult patients with MDS-EB without increasing hematological toxicity.

CH is common with advancing age and becomes nearly ubiquitous in middle age. Although typically asymptomatic, CH is associated with an increased risk of hematologic malignancies particularly myeloid neoplasms (MN), diverse non-malignant conditions, and all-cause mortality. Over the past decade, research has provided major insights into the origins of CH. In addition to aging, CH is promoted by environmental exposures, inherited genetic predisposition, and acquired conditions. Large-scale population and longitudinal sequencing studies have identified determinants of clonal behavior. Characterization of the natural history of CH has enabled the development of risk stratification models to identify individuals with CH at high risk of progression to MN, thereby providing a rationale for selecting patient populations best suited for therapeutic intervention trials. Emerging strategies include targeting mutation-specific vulnerabilities, modulating inflammatory pathways, reducing genotoxic therapy-induced clonal selection, and repurposing agents with efficacy in MN. In this review, we summarize current knowledge of the risk factors underlying CH development, highlight recent advances in understanding the determinants of clonal behavior including progression to MN, and discuss emerging therapeutic approaches for preventing malignant transformation and clinical trial design considerations.</p>","PeriodicalId":12964,"journal":{"name":"Haematologica","volume":" ","pages":"1536-1551"},"PeriodicalIF":7.9,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13136810/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146124768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The B-cell depleting agent rituximab is effective in restoring ADAMTS13 activity and therefore preventing relapses. However, the risk of relapse appears heterogeneous among patients, although the underlying causes are elusive. Preliminary reports suggested that African ancestry could be associated with decreased relapse-free survival (RFS). Data from the registry of the French National Thrombotic Microangiopathy Reference Center were used to further address the role of ethnicity on response and RFS after rituximab administration in the acute as well as in the preemptive setting. A total of 790 patients (134 patients of African ancestry and 656 patients of European ancestry) were included in the study. Time from rituximab administration to ADAMTS13 recovery was comparable between the two cohorts. Patients of African ancestry had inferior 3-year RFS after the first rituximab-treated episode compared to patients of European ancestry (P<0.05). In multivariate analyses, African ancestry was identified as an independent risk factor for relapse (hazard ratio [HR]=1.36; P<0.05), as well as male sex (HR=1.21; P<0.05) and type of index episode treated by rituximab (relapsed disease vs. initial episode, HR=1.62; P<0.05). Moreover, time to relapse shortened progressively after consecutive courses of rituximab, regardless of ethnicity (P<0.05).
