Abstract

Early post-allogeneic hematopoietic stem cell transplantation (allo-HSCT) relapse in patients with acute myeloid leukemia (AML) has an almost invariably dismal prognosis. Recent studies have demonstrated that FLT3 inhibition enhances the graft-versus-leukemia effect in vitro and in vivo. Thus, FLT-3 inhibitors may be viable treatment options in this setting. Here, we report three patients with FLT3 and NPM1 mutated AML who relapsed early after allo-HSCT and were treated with gilteritinib (associated with donor lymphocyte Infusion in two patients) to achieve long-term remission without a second transplantation.

FLT3/NPM1突变急性髓性白血病异基因干细胞移植后早期复发者使用吉特替尼后的长期缓解。
急性髓性白血病(AML)患者异基因造血干细胞移植(allo-HSCT)后早期复发的预后几乎无一例外都很糟糕。最近的研究表明,FLT3抑制剂可在体外和体内增强移植物抗白血病效应。因此,在这种情况下,FLT-3 抑制剂可能是可行的治疗选择。在此,我们报告了三名FLT3和NPM1突变的急性髓细胞性白血病患者,他们在接受异体造血干细胞移植(allo-HSCT)后早期复发,并接受了吉特替尼治疗(其中两名患者同时接受了供体淋巴细胞输注),从而获得了长期缓解,无需进行第二次移植。
