目的分析慢性粒细胞白血病(CML)异基因造血干细胞移植(allo—HSCT)治疗的危险因素,以利于更好地规避移植风险。方法回顾性研究分析121例接受allo—HSCT的CML患者。预后评估参照EBMT积分,即Gratwoh]积分,危险因素包括供者来源、患者年龄、患者移植前疾病状态、供患者性别差异、疾病确诊至移植时间。将患者分为3组:低危组(0~2分)、中危组(3~4分)和高危组(5分)。结果所有患者allo—HSCT后中位随访时间为37(1~126)个月,预期5年总生存(OS)率、无复发死亡(NRM)率及复发(RR)率分别为(56.8±5.0)%、(35.6±4.9)%和(12.9±3.7)%。其中低危组患者分别为(66.0±6.1)%、(28.8±6.0)%和(7.84-3.3)%,明显优于中危组[(47.2±8.7)%、(43.6±8.5)%和(18.7±8.1)%]和高危组[(16.8±15.2)%、(66.7±25.5)%和(50.0±25.0)%],差异具有统计学意义(P值分别为0.0015、0.045和0.0053)。结论EBMT危险因素积分系统能全面反映预测allo—HSCT治疗CML的疗效、复发率和移植相关死亡率。
Objective To analyze the risk factors of allogeneic stem cell transplantation (alIo-SCT) for ehroninc myeloid leukemia (CML) in an attempt to avoid transplant risks. Methods A total of 121 CML patients received allo-SCT were analyzed retrospectively. The risk analysis was based on the EBMT score ( gratwohl score) which included donor type, age of patients, disease status before transplantation, donor/recipient sex match and time interval between diagnosis to alIo-SCT. Patients were divided into 3 risk groups based on their EBMT score: low risk (score 0 -2), intermediate risk (3 -4) and high-risk (5). Results The median follow-up duration was 37 ( 1 - 126) months. The estimated 5-year overall survival (5 y-OS), non-relapse mortality (5 y-NRM) and relapse rate (5 y-RR) were (56.8 ±5.0)% , (35.6 ±4.9)% and (12.9±3.7)%, respectively. The5y-OS, NRM and RR were (66.0±6.1)%, (28.8±6.0)% and (7.8 ± 3.3 ) % in the low risk group being significantly superior to both intermediate-risk [ (47.2 ± 8.7 ) % , (43.6±8.5)% and (18.7 ±8. 1)%] and high-risk group [(16.8 ±15.2)%, (66.7 ±25.5)% and (50.0 ± 25.0) % ] (P = 0. 0015, 0.045 and 0.0053 for OS, NRM and RR respectively). Conelusion The EBMT risk score can effectively predict the overall outcome, relapse and transplant-related mortality of allo-SCT for CML patients.
