Abstract
T-cell acute lymphoblastic leukemia (T-ALL) is a highly invasive hematological malignancy originated from T-lineage progenitor cells. The clonal proliferation and aggregation of primordial cells in bone marrow inhibit normal hematopoietic function, resulting in a series of hematocytopenia and infiltration symptoms. SET-NUP214 fusion is a recurrent event that is common in adult male T-ALL patients. It originates from chromosome del(9)(q34.11; q34.13) or t(9; 9)(q34; q34). Hematopoietic stem cell transplantation (HSCT) can significantly improve the survival rate of these patients. Due to the poor prognosis of patients and high relapse rate after remission, more effective strategies need to be proposed to improve prognosis and prevent relapse. Chidamide is a novel oral benzamide histone deacetylase inhibitor (HDACi) that can exert anti-tumor effects through multiple mechanisms. Here we report chidamide maintenance therapy after allo-HSCT in patients with SET-NUP214 fusion positive T-ALL. Both patients improved effectively during follow-up, confirming the efficacy of chidamide in improving the condition of these patients and may provide valuable clinical information for the treatment of this rare and understudied disease.
