文题释义:
白血病微小残留病灶:
是指白血病患者经诱导化疗完全缓解后(或骨髓移植后),在体内残存有形态学上不能检测到的微量白血病细胞的状态。因此,采用灵敏度高、特异性强、经济方便的检测方法对微小残留病灶进行动态监测,对评估早期治疗反应、进行危险度分组,判断预后、预测复发,指导造血干细胞移植后复发患者治疗及个体化治疗尤为重要。
目前公认最有效的微小残留病灶检测方法:实时荧光定量PCR(qPCR)和多参数流式细胞术。①流式细胞术检测白血病微小残留病灶的基本原理是通过多参数定量分析白血病相关免疫表型(LAIPs),从而与正常和再生的骨髓细胞区分,灵敏度可达10-5;②qPCR技术通常选用免疫球蛋白(Ig)/T淋巴细胞受体(TCR)基因重排序列或融合基因作为基因标志,将急性淋巴细胞白血病细胞与正常细胞进行区分,灵敏度可达10-6。随着微小残留病灶检测技术可靠性的提高和标准化的统一,白血病患者的疗效也会显著提升。

 

摘要
背景:
异基因造血干细胞移植后复发是影响急性淋巴细胞白血病患者长期生存的主要问题。早期干预、预防移植后复发可以提高无病生存率、总体生存率,降低移植后死亡率。通过分子生物学技术监测微小残留病是目前广泛可靠、切实可行的方法。
目的:动态监测成人急性淋巴细胞白血病患者外周血单倍体造血干细胞移植后微小残留病指标,探讨其预测早期复发的意义。
方法:选择2011年6月至2017年6月在郑州大学第一附属医院行外周血单倍体造血干细胞移植治疗的急性淋巴细胞白血病患者53例,检测移植后1,3,6,12个月微小残留病指标变化,观察微小残留病水平与移植后复发的关系。
结果与结论:①微小残留病阳性组与阴性组的无病生存率分别为20.0%和65.8%,总生存率分别为50.8%和68.9%,差异均有显著性意义;②移植后骨髓微小残留病阳性患者16例,进行干预治疗后,4例患者微小残留病转阴,至今未复发;③血液学复发患者11例,分别给予酪氨酸激酶抑制剂靶向治疗、化疗、供者淋巴细胞输注和二次移植,最终血液学复发死亡,从发现微小残留病阳性到血液学复发的中位时间为100(7-190) d,期间给予干预,可延长复发时间;④1例患者拒绝治疗,最终复发死亡;⑤结果表明,急性淋巴细胞白血病患者外周血单倍体造血干细胞移植后动态监测微小残留病水平,预防早期复发,及时给予干预治疗,可以提高移植后无病生存率、总体生存率,延长复发时间。

Abstract:

BACKGROUND: Recurrence of acute leukemia after hematopoietic stem cell transplantation is one of the major problems affecting the long-term survival of patients. Early intervention to prevent ALL recurrence after transplantation can improve disease-free survival, overall survival and reduce post-transplant mortality. Monitoring of minimal residual disease (MRD) by flow cytometry and PCR-based molecular biology techniques is a widely reliable and practicable method.
OBJECTIVE: To dynamically monitor the MRD level of acute lymphoblastic leukemia after peripheral blood haploidentical hematopoietic stem cell transplantation and to explore its implications for predicting early relapse.
METHODS: A retrospective study was conducted in 53 patients with acute lymphoblastic leukemia who had underwgone peripheral blood haploidentical hematopoietic stem cell transplantation at the First Affiliated Hospital of Zhengzhou University from June 2011 to June 2017. The patients were followed up for postoperative 1, 3, 6, 12 months to observe the relation between MRD levels and relapse after transplantation.
RESULTS AND CONCLUSION: (1) The disease-free survival rate of MRD positive group and MRD negative group were 20.0% and 65.8%, respectively; and the overall survival rates were 50.8% and 68.9% in the two groups, respectively. There were significant differences between two groups. (2) Among 16 MRD positive patients accepting clinical intervention after transplantation, 4 patients presented with MRD negative and had no recurrence. (3) Eleven hematologic recurrence patients were given tyrosine kinase inhibitor-targeted therapy, chemotherapy, donor lymphocytes Infusion and secondary transplantation, but they eventually died. The median time from the discovery of MRD positive to hematologic recurrence was 100 (7-190) days, and during this period. Clinical intervention was confirmed to extend the recurrence time. In this study, one case refused clinical intervention, and eventually died of recurrence. Our findings indicate that dynamic monitoring of the MRD level in acute lymphoblastic leukemia patients after peripheral blood haploidentical transplantation can predict recurrence, by which the patients can be given early intervention to reduce the risk of recurrence and improve disease-free survival and overall survival.
