TL;DR
This study evaluates the effectiveness of allogeneic stem cell transplants for a type of bone marrow disorder called MDS-EB and compares outcomes across different subtypes under the new WHO 2022 classification.
Contribution
The paper introduces a survival comparison of WHO 2022 MDS subtypes after allogeneic hematopoietic stem cell transplantation.
Findings
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is effective for MDS-EB, with a 71.9% three-year overall survival rate.
MDS-IB1/IB2 patients had better survival and lower recurrence rates compared to MDS-biTP53 patients after allo-HSCT.
Single nucleated karyotype, high complication index, and severe intestinal GVHD are independent risk factors for poor survival.
Abstract
评估异基因造血干细胞移植(allo-HSCT)治疗骨髓增生异常综合征伴原始细胞增多(MDS-EB)的疗效和预后影响因素,比较WHO2022分类不同亚型患者的预后。 纳入2006年10月至2022年12月在中国医学科学院血液病医院接受allo-HSCT的282例MDS-EB患者,按照WHO 2022诊断标准重新分类为骨髓增生异常肿瘤伴原始细胞增多1型/2型(MDS-IB1/IB2)(222例)、MDS伴纤维化(MDS-f)(41例)和伴双等位基因TP53突变的MDS(MDS-biTP53)(19例)三组,对其临床资料进行回顾性分析。 ①282例患者中位年龄46(15~66)岁,男191例,女91例,MDS-EB1 118例(42%),MDS-EB2 164例(58%)。②282例MDS-EB患者中256例(90.8%)移植后获得造血重建,原发植入功能不良11例(3.9%),继发植入功能不良15例(5.3%)。移植后100 d急性移植物抗宿主病(GVHD)累积发生率为(42.6±3.0)%,Ⅱ~Ⅳ度急性GVHD累积发生率为(33.0±2.8)%;移植后1年慢性GVHD累积发生率为(31.0±2.9)%。移植后128例(45.4%)患者发生巨细胞病毒(CMV)感染,63例(22.3%)患者发生菌血症,35例(12.4%)患者发生肺部真菌感染,17例(6.0%)患者发生EB病毒感染。③移植后中位随访时间为22.1(19.2~24.7)个月,3年总生存(OS)率、无病生存(DFS)率分别为71.9%(95%CI 65.7%~78.6%)、63.6%(95%CI 57.2%~70.7%),3年非复发死亡率(NRM)为17.9%(95%CI 13.9%~22.9%),3年累积复发率(CIR)为9.8%(95%CI 6.7%~13.7%)。影响移植后OS的独立危险因素包括单体核型(MK)(P=0.004,HR=3.26,95%CI 1.46~7.29)、造血干细胞移植合并症指数(HCI-CI)≥3分(P<0.001,HR=2.86,95%CI…
