文题释义:
异基因造血干细胞移植:
是血液系统恶性疾病、部分免疫缺陷性疾病、遗传性疾病、代谢性疾病、及部分实体瘤的重要治疗手段,但是移植后疾病复发是导致移植患者死亡的首要原因。
微小残留病变(microresidual disease,MRD):是指白血病诱导化疗完全缓解后(或骨髓移植治疗后),在体内残留少量白血病细胞的状态。

 

摘要
背景:
白血病患者经过治疗后,临床和血液细胞学达到完全缓解后体内仍残留白血病细胞,因此微小残留病变(minimal residual disease,MRD)被认为与患者的复发有高度相关性。MRD状态是否会影响异基因造血干细胞移植后患者的生存,仍是争议的焦点。
目的:探讨中老年急性髓系白血病患者异基因造血干细胞移植前MRD检测的意义。  
方法:计算机检索CNKI、维普数据库、万方数据库、PubMed数据库、Cochrane图书馆及Embase数据库,查找中老年急性髓系白血病患者异基因造血干细胞移植前MRD检测意义相关临床研究。采用STAT 12.0进行数据分析,应用HR及其95%CI表示其关联强度。
结果与结论:共纳入8项研究,涉及急性髓系白血病患者908例,其中MRD阳性患者227例,MRD阴性患者681例。Meta分析发现,异基因造血干细胞移植前MRD阳性患者总生存期(HR=11.81,95%CI:4.76-29.31,P=0.000 1)、无疾病进展期(HR=10.75,95%CI:3.73-30.96,P=0.000 1)、累积复发率(HR=44.15,95%CI:13.20-147.69,P=0.000 1)、非复发死亡率(HR=2.14,95%CI:1.48-3.10,P=0.001)均明显劣于MRD阴性患者,差异有统计学意义(P < 0.05)。说明中老年急性髓系白血病患者异基因造血干细胞移植前MRD阳性可能提示不良预后,异基因造血干细胞移植前有必要采用合理的方法检测MRD状态。

Abstract:

BACKGROUND: Residual leukemia cells still remain in the body of leukemia patients who are in complete remission at clinical and blood cytology levels. Therefore, minimal residual disease (MRD) is considered to be highly correlated with leukemia recurrence. Whether the MRD status affects the survival of patients after allogeneic hematopoietic stem cell transplantation remains the focus of controversy.
OBJECTIVE: To evaluate the prognostic role of minimal residual disease (MRD) testing before allogeneic hematopoietic stem cell transplantation.
METHODS: Published literature regarding MRD testing in middle-aged and elderly acute myeloid leukemia patients before allogeneic hematopoietic stem cell transplantation within CNKI, VIP Database, WanFang Database, PubMed, Embase, and the Cochrane Library were searched in this meta-analysis. Data were analyzed with the Stata 12.0 software package using pooled hazard ratios (HR) with 95% confidence intervals (CI).
RESULTS AND CONCLUSION: A total of 8 studies involving 908 patients (227 positive for MRD and 681 negative for MRD) were included. The results of meta-analysis showed that pre-transplant MRD was associated with poor overall survival (HR=11.81, 95%CI: 4.76-29.31, P=0.000 1), disease-free survival (HR=10.75, 95%CI: 3.73-30.96, P=0.0001), cumulative incidence of relapse (HR=44.15, 95%CI: 13.20-147.69, P=0.000 1), and non-relapse mortality (HR=2.14, 95%CI: 1.48-3.10, P=0.001). To conclude, pre-transplant MRD (positive for MRD) may indicate poor prognosis in middle-aged and elderly acute myeloid leukemia patients. Therefore, a rational method to screen MRD is necessary prior to allogeneic hematopoietic stem cell transplantation.
