Abstract：
Twelve DEK-NUP214 fusion gene-positive patients with acute myeloid leukemia and on allo-HSCT treatment at the Hematology Hospital of the Chinese Academy of Medical Sciences from November 2016 to August 2022 were included in the study, and their clinical data were retrospectively analyzed. The patients comprised five men and seven women with a median age of 34 (16-52) years. At the time of diagnosis, all the patients were positive for the DEK-NUP214 fusion gene. Chromosome karyotyping analysis showed t (6;9) (p23;q34) translocation in 10 patients (two patients did not undergo chromosome karyotyping analysis), FLT3-ITD mutation was detected in 11 patients, and high expression of WT1 was observed in 11 patients. Nine patients had their primary disease in the first complete remission state before transplantation, one patient had no disease remission, and two patients were in a recurrent state. All patients received myeloablative pretreatment, five patients received sibling allogeneic hematopoietic stem cell transplantation, and seven patients received haploid hematopoietic stem cell transplantation. The median number of mononuclear cells in the transplant was 10.87 (7.09-17.89) ×10(8)/kg, and the number of CD34(+) cells was 3.29 (2.53-6.10) ×10(6)/kg. All patients achieved blood reconstruction, with a median time of 14 (10-20) days for neutrophil implantation and 15 (9-27) days for platelet implantation. The 1 year transplant-related mortality rate after transplantation was 21.2%. The cumulative recurrence rates 1 and 3 years after transplantation were 25.0% and 50.0%, respectively. The leukemia free survival rates were (65.6±14.0) % and (65.6±14.0) %, respectively. The overall survival rates were (72.2±13.8) % and (72.2±13.8) %, respectively.
2016年11月至2022年8月期间，12例DEK-NUP214融合基因阳性急性髓系白血病患者在中国医学科学院血液病医院接受异基因造血干细胞移植（allo-HSCT）。12例患者中男5例，女7例，中位年龄34（16~52）岁。12例患者初诊时均检出DEK-NUP214融合基因阳性，10例患者染色体核型分析显示t（6;9）（p23;q34）易位（2例患者未行染色体核型分析），11例患者检出FLT3-ITD突变，11例患者检出WT1高表达。9例患者allo-HSCT前处于第一次完全缓解状态，1例患者疾病未缓解，2例患者处于复发状态。所有患者均接受清髓性预处理，5例患者接受同胞全相合造血干细胞移植，7例患者接受单倍体造血干细胞移植。移植物单个核细胞中位数为10.87（7.09~17.89）×10(8)/kg，CD34(+)细胞中位数为3.29（2.53~6.10）×10(6)/kg。所有患者均获得造血重建，粒细胞植入中位时间为14（10~20）d，血小板植入中位时间为15（9~27）d。移植后1年移植相关死亡率为21.2%。移植后1、3年累积复发率分别为25.0%、50.0%，无白血病生存率为（65.6±14.0）%，总生存率为（72.2±13.8）%。.
