文题释义:
造血干细胞移植:
是通过大剂量放化疗预处理,清除受者体内的肿瘤或异常细胞,再将自体或异体造血干细胞移植给受者,使受者重建正常造血及免疫系统。目前广泛应用于恶性血液病、非恶性难治性血液病、遗传性疾病和某些实体瘤治疗。
急性白血病:是造血干细胞的恶性克隆性疾病,发病时骨髓中异常的原始细胞及幼稚细胞(白血病细胞)大量增殖,蓄积于骨髓和其他造血组织并抑制正常造血,广泛浸润肝、脾、淋巴结等脏器。临床表现为贫血、出血、感染和浸润等征象。

 

摘要
背景:
对于高危急性白血病的移植治疗供者的优先选择仍存在争议。
目的:比较非血缘外周血干细胞移植与同胞相合外周血干细胞移植治疗高危急性白血病的疗效。
方法:纳入2008年1月至2016年1月就诊的高危急性白血病患者65例,根据患者意愿并结合自身情况,其中30例患者选择非血缘外周血干细胞移植,35例选择同胞相合外周血干细胞移植,利用卡方检验、Kaplan-Meier生存分析法等比较分析2组患者的植入、造血重建、移植物抗宿主病、复发死亡和远期生存情况。
结果与结论:①两组的植入率,粒系、血小板造血重建时间和急慢性移植物抗宿主病的总发生率及其发生类型差异均无显著性意义(P均> 0.05);②非血缘外周血干细胞移植组的复发率、总死亡率和移植相关死亡率分别为10.0%、50.0%和40.0%,与同胞相合外周血干细胞移植组(20.0%、48.6%和25.7%)比较差异均无显著性意义(P均> 0.05);③非血缘外周血干细胞移植组的预计2年累积无病生存率和总生存率分别为(49.4±9.2)%和(52.6±9.2)%,与同胞相合外周血干细胞移植组[(53.9±8.5)%和(53.9±8.5)%]比较差异均无显著性意义(P均> 0.05);④结果表明,当缺乏同胞相合外周血干细胞移植供者时,非血缘外周血干细胞移植可作为有效替代。

Abstract:

BACKGROUND: Donor selection for high-risk acute leukemia is still controversial.
OBJECTIVE: To compare the therapeutic efficacy of the unrelated donor peripheral blood and matched sibling allogeneic hematopoietic stem cell transplantation for high-risk acute leukemia.
METHODS: Total 65 patients with high-risk acute leukemia treated during January 2008 to January 2016 were included, in which 30 patients chose the unrelated donor peripheral blood stem cell transplantation (UD), and other 35 chose the matched sibling allogeneic hematopoietic stem cell transplantation (MS) according to the wishes of patients and their own situation. After treatment, the chi-square test, Kaplan-Meier survival analysis method, and other methods were used to compare the implanted and hematopoietic reconstitution, the occurrence of graft-versus-host disease, relapse mortality and long-term survival between the two groups.
RESULTS AND CONCLUSION: The implantation rate, platelet hematopoietic reconstitution time, the incidence of acute and chronic graft-versus-host disease, and its type exhibited no significant differences between the two groups (P > 0.05). The relapse rate, total death rate, and transplant-related mortality rates were 10.0%, 50.0%, and 40.0% in the UD group and 20.0%, 48.6%, and 25.7% in the MS groups, respectively, and the intergroup difference was insignificant (P > 0.05). The expected 2-year cumulative disease-free free survival and overall survival rates were (49.4±9.2)% and (52.6±9.2)% in the UD group and (53.9±8.5)% and (53.9±8.5)% in the MS group, respectively, and the intergroup difference was also insignificant ( > 0.05). Our experimental findings show that unrelated donor peripheral blood stem cell transplantation can be used as an effective alternative in the absence of sibling donors.
