-related myelodysplastic syndrome (-MDS) is a unique predisposition syndrome with a high risk of leukemic transformation. This systematic review synthesizes current literature and presents two illustrative pediatric -MDS cases. Data retrieval from eight cohort and case-control studies provides comprehensive analysis on disease features, diagnostic complexities, management, and outcomes related to hematopoietic stem cell transplantation (HSCT) in -related myeloid malignancies. Additionally, two pediatric cases are included to exemplify clinical and therapeutic challenges in real-world setting. The literature data demonstrates high incidence of monosomy 7, and recurrent infections as the most common clinical feature, followed by immunodeficiency and lymphedema. Prognosis clearly worsens with age and HSCT remains the only curative treatment. patients undergoing HSCT experience high rates of graft versus host disease (GvHD) as well as unique neurological, thrombotic, and infectious complications. Transplant-related mortality (TRM) is linked to GvHD and infections. Post-transplant cyclophosphamide (PT/Cy) strategies seem to improve survival by reducing GvHD incidence. Overall survival (OS) remains variable across groups. The first case presents rapid disease progression to pulmonary alveolar proteinosis (PAP) and leukemic transformation, further developing severe HSCT complications. The second case addresses novel mutation and raises concerns regarding alternative prophylactic and therapeutic strategies in transplant setting. Collaborative efforts aim to enhance understandings of -related myeloid malignancies and guide towards more effective management approaches.
相关骨髓增生异常综合征(-MDS)是一种具有白血病转化高风险的独特易患综合征。本系统综述综合了当前文献,并展示了两例典型的儿童-MDS病例。从八项队列研究和病例对照研究中检索的数据,对与造血干细胞移植(HSCT)相关的骨髓恶性肿瘤的疾病特征、诊断复杂性、管理和结局进行了全面分析。此外,纳入了两例儿科病例,以例证现实环境中的临床和治疗挑战。文献数据显示,7号染色体单体发生率高,反复感染是最常见的临床特征,其次是免疫缺陷和淋巴水肿。预后明显随年龄恶化,HSCT仍然是唯一的治愈性治疗方法。接受HSCT的患者发生移植物抗宿主病(GvHD)以及独特的神经、血栓形成和感染并发症的发生率很高。移植相关死亡率(TRM)与GvHD和感染有关。移植后环磷酰胺(PT/Cy)策略似乎通过降低GvHD发生率来提高生存率。总体生存率(OS)在各群体中仍然存在差异。第一个病例显示疾病迅速进展为肺泡蛋白沉积症(PAP)和白血病转化,进而出现严重的HSCT并发症。第二个病例涉及新的突变,并引发了对移植环境中替代预防和治疗策略的关注。合作努力旨在增进对相关骨髓恶性肿瘤的了解,并指导采用更有效的管理方法。
