摘要:

目的 探讨微量残留病(MRD)监测在ETV6/RUNX1融合基因阴性、阳性急性B淋巴细胞白血病(B-ALL)患儿预后中的意义。方法 收集2018年1月—2021年6月郑州大学附属儿童医院234例B-ALL患儿临床资料,其中ETV6/RUNX1融合基因阳性78例(阳性组)、阴性156例(阴性组)。比较阳性组和阴性组无复发生存期(RFS)差异;统计2个组诱导化疗第15天、第33天和巩固治疗开始前(第12周)MRD检测结果,分别记为MRD1、MRD2、MRD3;分析2个组组内MRD1、MRD2、MRD3在B-ALL患儿预后中的意义。结果 与阴性组比较,阳性组RFS延长(P=0.029)。在阴性组内,MRD1阴性和阳性患儿RFS差异无统计学意义(P>0.05);MRD2、MRD3阴性患儿RFS均长于MRD2、MRD3阳性患儿(P<0.05);MRD3阳性是B-ALL患儿预后的独立影响因素(比值比值为=3.678,95%可信区间为1.254~10.785,P=0.018)。在阳性组内。MRD1、MRD2阴性和阳性患儿RFS差异无统计学意义(P>0.05);MRD3阴性患儿RFS长于MRD3阳性患儿;多因素分析结果显示,MRD3阳性并非患儿RFS的独立影响因素(P>0.05)。结论 监测MRD对ETV6/RUNX1融合基因阴性B-ALL患儿预后的意义更大,建议持续监测;对于ETV6/RUNX1融合基因阳性患儿,MRD监测意义较弱,临床可根据实际情况决定是否采用。

Abstract:

Objective To analyze the significance of minimal residual disease(MRD)dynamic monitoring in the prognosis of acute B-lymphoblastic leukemia(B-ALL) children with positive and negative ETV6/RUNX1 fusion genes. Methods The clinical data of 234 children with B-ALL in the Children's Hospital of Zhengzhou University from January 2018 to June 2021 were collected. There were 78 children with ETV6/RUNX1 fusion gene(positive group) and 156 children without ETV6/RUNX1 fusion gene(negative group). The differences in relapse-free survival(RFS) between positive and negative groups were compared. The results of MRD in the 2 groups on the 15th day(MRD1) and the 33rd day(MRD2) of induction chemotherapy and before the start of consolidation therapy(the 12th week,MRD3) were calculated,and the significance of MRD1,MRD2 and MRD3 in the prognosis of B-ALL children was analyzed. Results Compared with negative group,the RFS in positive group were prolonged(P=0.029). In negative group,there was no statistical significance in RFS between MRD1 negative and positive children(P>0.05),but the RFS of MRD2 and MRD3 negative children were longer than those of MRD2 and MRD3 positive children(P<0.05),and MRD3 was an independent risk factor for RFS odds ratio was 3.678, 95% confidence interval 1.254-10.785,P=0.018). In positive group,there was no statistical significance in RFS between MRD1 and MRD2 positive and negative children(P>0.05),but the RFS of MRD3 negative children was longer than those of MRD3 positive children,but MRD3 was not an independent risk factor for RFS(P>0.05). Conclusions MRD dynamic monitoring has prognostic significance for B-ALL children with negative ETV6/RUNX1 fusion gene,and MRD dynamic monitoring should be carried out. For positive ETV6/RUNX1 fusion gene children,the significance of MRD dynamic monitoring is weak. Clinic can decide whether to use according to actual situation.
