摘要

晚期系统性肥大细胞增多症（AdvSM）是一种罕见的、限制生命的肥大细胞（MC）肿瘤，约70%的患者患有相关的血液肿瘤（AHN）。Avapritinib是一种靶向KIT D816V的选择性酪氨酸激酶抑制剂，在1期EXPLORER（NCT02561988）和2期PATHFINDER（NCT03580655）研究中显示出强大的活性，可将临床转化为持久反应。我们报告了三名接受阿伐普利替尼治疗的AdvSM AHN患者，他们获得了SM的完全缓解（CR），并成功桥接至异基因造血细胞移植（allo-HCT）。另外两个病例强调了AHN成分中克隆进化的风险，以及在靶向治疗时需要密切监测。

Advanced Systemic Mastocytosis with associated haematological neoplasm: Treatment with avapritinib can facilitate successful bridge to allogeneic haematopoietic cell transplant

Advanced systemic mastocytosis (AdvSM) is a rare, life-limiting mast cell (MC) neoplasm, with approximately 70% patients having an associated haematological neoplasm (AHN). Avapritinib, a selective tyrosine kinase inhibitor targeting KIT D816V, has shown potent activity translating clinically into durable responses in the phase 1 EXPLORER (NCT02561988) and phase 2 PATHFINDER (NCT03580655) studies.

We report three patients with AdvSM-AHN on avapritinib who achieved complete remission (CR) of SM and were successfully bridged to allogeneic haematopoietic cell transplant (allo-HCT). Two cases additionally highlight the risk of clonal evolution within the AHN component and requirement for close monitoring while on targeted therapy.
