Acute myeloid leukemia with FIP1‐like‐1‐platelet‐derived growth factor receptor α fusion gene positive progressed from idiopathic hypereosinophilic syndrome: report of one case and review of literature / 白血病·淋巴瘤

ABSTRACT

Objective To improve the understanding of idiopathic hypereosinophilic syndrome (HES) and to be aware of its potential of transforming to acute myeloid leukemia (AML). Methods The clinical data of one patient diagnosed with HES progressed to AML in the 923rd Hospital of the Peopleˊs Liberation Army Joint Service Support Force were analyzed, and relevant literatures were reviewed. Results The patient was diagnosed with idiopathic HES that progressed to AML with FIP1-like-1-platelet-derived growth factor receptor α (FIP1L1-PDGFRA) after 2 years. The patients achieved complete remission after the treatment of chemotherapy combined with tyrosine kinase inhibitor and then received hematopoietic stem cell transplantation. The patient had more than 1 year disease-free survival until the deadline. Conclusion Idiopathic HES has the potential to transform to AML with FIP1L1-PDGFRA fusion gene positive, therefore regular follow-up should be emphasized.
