摘要
目的:观察非清髓异基因外周造血干细胞移植(NAST)对难治性恶性血液病的疗效。方法:采用NAST治疗 3例慢性粒细胞白血病加速期(CML -AP)、1例骨髓增生异常综合征(MDS-RAEB T)患者。非清髓预处理方案:氟达拉宾 (Flud)30mg·m-2·d-1×6d,白消安(Bu)4mg·kg-1·d-1×2d,环磷酰胺(CTX)600mg·d-1×2d,3例CML- AP患者在此基 础上加用阿糖胞苷(Ara c)。结果:4例患者造血均顺利恢复,ANC>0.5×109/L平均为12天,BPC>20×109/L平均为11天。 +30天时经短串联重复序列(STR)- PCR检测3例患者为完全嵌合体(CC),1例慢粒患者为混合嵌合体(MC),+90天时全部 患者均处于CC。分别随访4月～16月,均无病存活。结论:非清髓异基因外周造血干细胞移植是治疗CML- AP、MDS -RAEB T 等难治性恶性血液病的有效手段。
Objective:To investigate the application of nonmyeloablative allogenetic peripheral blood hematopoietic stem cell transplantation in the treatment of refractory hematologic malignancies.Methods:4 patients received NAST. Of them,3 were chronic myeloid leukemia in accelerated phase(CML-AP),and 1 was myelodysplastic syndrome-refractory anemia with excess blasts in transformation(MDS-RAEB-T).Nonmyeloablative regimens included fludarabine 30mg·m -2·d -1×6d,busulphan 4mg·kg -1·d -1×2d,CTX 600mg·d -1×2d,±Ara-c.Results:All 4 patients were successfully engrafted with donor cells(3 with complete chimerism,1 with mixed chimerism detected by STR-PCR method) on +30d.The median time for neutrophil recovering to >0.5×10 9/L and platelet>20×10 9/L were!12 days and 11 days post-trasnsplant. All patients were alive and disease-free with a median follow-up time of 6(4～16)months.Conclusion:NAST is an effective therapy for patients with CML-AP and MDS-RAEB-T.
