: Patients with acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) have historically poor outcomes with conventional chemotherapy regimens. Current treatment strategies focus on intensive induction therapy followed by allogeneic stem cell transplant or a less intensive approach with hypomethylating agents with or without venetoclax. CPX-351 is a liposomal formulation of cytarabine and daunorubicin that has been shown to significantly improve response rates and survival compared with 7 + 3 (continuous infusion cytarabine plus anthracyclines). Despite the approval of CPX-351 for AML-MRC, overall prognosis remains poor with an unmet need to develop novel therapeutic strategies for this patient population.: This article reviews the data for existing therapeutic options for patients with AML-MRC and the emerging therapies undergoing clinical trial development for this patient population.: The development of CPX-351 as a more effective induction therapeutic backbone for patients with AML-MRC presents an opportunity to investigate novel combination regimens in order to further improve outcomes. Promising emerging therapeutic modalities include immunotherapeutic strategies, small-molecule inhibitors and targeted agents. Unfortunately, there have been few clinical trials focusing on patients with AML-MRC with reliance instead on subgroup analyses. Clinical trials focused specifically on this patient population are urgently needed.
: 具有伴 MDS 相关改变的急性髓系白血病(AML-MRC)的患者采用传统化疗方案的历史预后较差。目前的治疗策略侧重于强化诱导治疗,随后进行同种异体干细胞移植,或采用低强度方案联合或不联合维奈托克的去甲基化药物。CPX-351 是阿糖胞苷和柔红霉素的脂质体制剂,与 7+3(持续输注阿糖胞苷联合蒽环类药物)相比,已显示出可显著提高缓解率和生存率。尽管 CPX-351 已被批准用于 AML-MRC,但总体预后仍然较差,因此需要为这一患者群体开发新的治疗策略。
: 本文综述了 AML-MRC 患者现有治疗选择的数据,以及正在进行临床试验开发的新兴治疗方法。
: CPX-351 作为 AML-MRC 患者更有效的诱导治疗基础,为进一步改善结果提供了机会,可以研究新的联合方案。有前途的新兴治疗方式包括免疫治疗策略、小分子抑制剂和靶向药物。不幸的是,很少有临床试验专门针对 AML-MRC 患者进行,而是依赖于亚组分析。迫切需要专门针对这一患者群体的临床试验。
