Within SM, indolent SM (ISM) is the more frequent subtype. Adult patients with CM but without an extracutaneous biopsy are classified as having mastocytosis in the skin (MIS), a provisional diagnosis. Mastocytosis patients may experience a wide range of symptoms that significantly impact their quality of life (QoL). In France, the estimated prevalence of mastocytosis and the burden of symptoms remain unknown. To address this, we conducted a national online survey to estimate the number of mastocytosis diagnoses and assess the burden of symptoms from the physician's perspective. Overall, 1169 of the 6239 physicians solicited completed the survey. These physicians reported managing 4121 patients of whom only 53% had ISM. By contrast, CM and MIS were reported in more patients than expected at 17% and 25% respectively. The estimated prevalence of mastocytosis in France was 8.5 per 100,000, which is lower than recent epidemiological studies and is associated with significant regional variability (p < 0.001). Among patients with ISM or MIS, 53% experienced moderate to severe symptoms-mainly affecting the skin, digestive system and general health-which impacted most QoL domains assessed. These findings highlight the need to improve awareness, access to diagnostic workup for mastocytosis (especially for patients with MIS and CM) and enhance QoL for patients.</p>","PeriodicalId":135,"journal":{"name":"British Journal of Haematology","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145032369","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Children often present with more aggressive clinical features and show distinct treatment response patterns. Recent genomic and transcriptomic studies have highlighted a higher prevalence of germline variants in haematopoiesis-related genes and unique cytogenetic alterations, as well as age-specific distributions of BCR and ABL1 breakpoints. Transcriptomic profiling of paediatric CML stem cells reveals differential expression signatures that suggest the presence of distinct signalling networks. Somatic mutations-particularly in ASXL1-are observed at diagnosis in some children, though their prognostic relevance remains uncertain. Additionally, while the BCR::ABL1 transcript subtype is known to affect treatment-free remission in adults, its role in paediatric CML is still unclear. Collectively, these findings support the notion that paediatric CML may constitute a biologically distinct disease rather than simply a younger form of adult CML.
