摘要:

目的 探讨急性髓系白血病(AML)患者异基因造血干细胞移植(allo-HSCT)后复发的影响因素,为临床早期识别高危因素,及时采取干预措施提供依据。方法 回顾性分析2017年1月1日—2020年12月31日上海交通大学医学院附属第一人民医院行allo-HSCT的132例非M3型AML患者移植相关临床数据。采用Cox回归分析评价AML患者移植后复发和无复发生存的影响因素。结果 132例患者中,复发25例,中位复发时间为5个月。复发组与非复发组TP53基因突变情况、移植前状态比较,差异有统计学意义(P<0.05)。多因素Cox回归分析结果显示,初诊白细胞计数≥100×109/L、TP53基因突变、移植前未缓解(NR)是AML患者移植后复发的独立危险因素(P<0.05)。Log-rank χ2检验结果显示,初诊白细胞计数≥100×109/L组与白细胞计数<100×109/L组、TP53基因突变组与野生型组,移植前NR组与完全缓解(CR)组总无复发生存(RFS)率差异有统计学意义(P<0.05)。结论 初诊时高白细胞计数、TP53基因突变、移植前NR可导致AML患者移植后复发风险增加。

Abstract:

Objective To investigate the risk factors of relapse following allogeneic hematopoietic stem cell transplantation(allo-HSCT) in patients with acute myeloid leukemia(AML),and to provide a reference for early clinical identification of high risk factors and timely intervention. Methods A retrospective study of 132 patients diagnosed with AML and treated with allo-HSCT in Shanghai General Hospital of Shanghai Jiao Tong University School fo Medicine from January 1st 2017 to December 31st 2020 was performed. Cox regression analysis was used to evaluate the influence factors of relapse following allo-HSCT. Results Out of 132 cases,25 cases relapsed after allo-HSCT. The median time of relapse was 5 months. TP53 gene mutation and pre-transplant status had statistical significance between relapsed group and non-relapsed group(P<0.05). Multivariate Cox regression analysis showed that white blood cell count ≥100×109/L at first diagnosis,TP53 gene mutation and no remission(NR) before transplantation were independent risk factors for relapse after allo-HSCT(P<0.05). Log-rank χ2 test showed that there was statistical significance in relapse free survival(RFS) between white blood cell count ≥100×109/L and <100×109/L groups at first diagnosis,TP53 gene mutation group and wild type group,NR group and complete remission(CR) group before transplantation(P<0.05). Conclusions White blood cell count ≥100×109/L at first diagnosis,TP53 gene mutation and NR before transplantation are associated with high risk of relapse after allo-HSCT in AML patients.
