The integration of next-generation sequencing (NGS) and advanced cytogenetic diagnostics into routine clinical practice is reshaping frontline treatment of acute myeloid leukemia (AML) in both fit and unfit patients. Molecular profiling now enables personalized treatment strategies, particularly for patients harboring mutations in FLT3, IDH1, IDH2, KMT2A, and NPM1. Small molecule inhibitors, first reserved for relapsed/refractory disease, are increasingly used in the upfront setting. However, universal NGS testing at diagnosis is critical to identify eligible patients for these targeted therapies. In patients lacking actionable mutations, treatment can still be refined using karyotypic abnormalities or high-risk features suggestive of antecedent MDS. In our practice, we continue to use 7 + 3 induction for fit patients, adding midostaurin or quizartinib for FLT3-mutated AML, or gemtuzumab ozogamicin for core binding factor (CBF) AML expressing CD33. For patients with therapy-related AML or AML with myelodysplasia-related changes, CPX-351 is our standard induction approach. For unfit patients, we generally offer hypomethylating agents with venetoclax. In the presence of IDH1 mutations, we consider azacitidine combined with ivosidenib. If venetoclax is contraindicated or not tolerated, targeted therapies such as gilteritinib, ivosidenib, or enasidenib may be appropriate based on mutation profile. However, we try to identify clinical trials for all our patients at diagnosis. One of the more exciting recent developments is the emergence of menin inhibitors for patients with KMT2A rearrangements or NPM1 mutations. While several agents have received FDA approval or breakthrough status in the relapsed/refractory setting, they are now being actively studied as frontline options with promising results. When feasible, clinical trial enrollment should be considered for newly diagnosed patients with these alterations. As the therapeutic landscape for AML continues to evolve, timely molecular characterization is more essential than ever to optimize outcomes and select the most appropriate frontline strategy.
将下一代测序(NGS)和先进的细胞遗传学诊断整合到常规临床实践中,正在重塑适合和不适合的急性髓系白血病(AML)患者的一线治疗。分子谱分析现在能够实现个性化治疗策略,特别是对于携带FLT3、IDH1、IDH2、KMT2A和NPM1突变的患者。小分子抑制剂最初仅用于复发/难治性疾病,现在越来越多地用于一线治疗。然而,诊断时进行普遍的NGS检测对于确定这些靶向治疗的合适患者至关重要。在缺乏可操作突变的患者中,仍可根据核型异常或提示既往骨髓增生异常综合征(MDS)的高危特征来优化治疗。在我们的实践中,对于适合的患者,我们继续使用7+3诱导方案,对于FLT3突变的AML患者加用米哚妥林或奎扎替尼,对于表达CD33的核心结合因子(CBF)AML患者加用吉妥珠单抗奥唑米星。对于治疗相关AML或伴有骨髓增生异常相关改变的AML患者,CPX-351是我们的标准诱导方案。对于不适合的患者,我们通常提供去甲基化药物联合维奈克拉。在存在IDH1突变的情况下,我们考虑阿扎胞苷联合艾伏尼布。如果维奈克拉禁忌或不耐受,根据突变谱,吉列替尼、艾伏尼布或恩杂鲁胺等靶向治疗可能是合适的。然而,我们会在诊断时为所有患者寻找临床试验。最近一项更令人兴奋的进展是出现了针对KMT2A重排或NPM1突变患者的Menin抑制剂。虽然几种药物已在复发/难治性环境中获得FDA批准或突破性地位,但它们现在正作为一线选择进行积极研究,结果很有前景。在可行的情况下,应考虑为新诊断的有这些改变的患者进行临床试验入组。随着AML治疗格局的不断演变,及时的分子特征分析比以往任何时候都更重要,以优化治疗结果并选择最合适的一线策略。
