Abstract

Recent advances in remission induction treatment strategies for acute myeloid leukemia (AML) have improved the rates of complete remission (CR) and overall survival (OS), owing to a concerted effort to tailor therapies toward specific AML subtypes. However, without effective post-remission therapy, most patients will relapse. The extent to which post-remission therapies is individualized in the current paradigm is quite varied. Core binding factor (CBF) AML is typically treated with post-remission high-dose cytarabine (HiDAC) without allogeneic hematopoietic stem cell transplantation (HSCT), whereas those with intermediate or adverse-risk cytogenetics are treated with post-remission cytarabine followed by allogeneic HSCT in CR1 when feasible. A lack of clarity regarding the proper dosing of post-remission cytarabine has made consensus building on dosing and schedule a challenge. CBF AML benefits most from high-dose cytarabine (HiDAC), and dasatinib appears promising as an adjunct for those for KIT-mutated CBF AML. Other than series using CPX-351 or lomustine in older adults, multiagent chemotherapy approaches have resulted in excess toxicity without a survival benefit. Neither hypomethylating agents nor gemtuzumab ozogamicin have shown a material OS benefit. Targeted agents such as FLT3 inhibitors and IDH1/IDH2 inhibitors show potential for the patients who harbor these druggable targets, but few data are available. Many studies evaluating post-remission strategies to target AML in the MRD-positive state are already underway, and these remain a promising area of investigation.

摘要

近年来,急性髓系白血病(AML)缓解诱导治疗策略的进展提高了完全缓解(CR)和总生存率(OS),这是因为人们齐心协力针对特定的 AML 亚型定制治疗方法。然而,如果没有有效的缓解后治疗,大多数患者将复发。在当前的模式下,缓解后治疗在多大程度上个体化差异很大。核心结合因子(CBF)AML 通常采用缓解后高剂量阿糖胞苷(HiDAC)治疗,而不进行异基因造血干细胞移植(HSCT),而那些具有中间或不良风险细胞遗传学的患者在 CR1 时接受缓解后阿糖胞苷治疗,然后在可行时进行异基因 HSCT。缓解后阿糖胞苷的适当剂量缺乏明确性,使得在剂量和方案方面达成共识具有挑战性。CBF AML 最受益于高剂量阿糖胞苷(HiDAC),达沙替尼似乎是 KIT 突变的 CBF AML 的辅助治疗有前途的药物。除了在老年人中使用 CPX-351 或洛莫司汀的系列研究外,多药化疗方法的毒性增加,但没有生存获益。去甲基化剂和 gemtuzumab ozogamicin 均未显示出明显的 OS 获益。针对携带这些可治疗靶点的患者的靶向药物,如 FLT3 抑制剂和 IDH1/IDH2 抑制剂等具有潜力,但可用数据很少。目前已有许多研究正在评估针对 MRD 阳性状态的 AML 的缓解后策略,这仍然是一个很有前途的研究领域。
