HLA半相合外周血造血干细胞移植治疗急性白血病的临床观察

目的：探讨HLA半相合外周血造血干细胞移植（peripheral blood stem cell transplantation，PBSCT）治疗急性白血病的效果及安全性。方法：4例急性白血病行HLA半相合PBSCT，其中急性淋巴细胞白血病2例，急性非淋巴细胞白血病2例，移植时均处于完全缓解状态。HLA配型1、2个位点不合各1例，3个位点不合2例。预处理方案由全身照射或白消安、阿糖胞苷、环磷酰胺、甲基洛莫司汀组成。移植物抗宿主病（graft versus hostdisease，GVHD）的预防采用环胞素、甲氨蝶呤、麦考酚吗乙酯、抗胸腺细胞球蛋白四联方案。结果：4例均获得造血功能重建。2例出现Ⅰ度急性GVHD，2例出现Ⅱ度急性GVHD。1例并发巨细胞病毒间质性肺炎，2例并发真菌肺炎。至今3例无病存活29、15和2个月，1例死亡。结论：HLA半相合PBSCT疗效较好、安全可行，为无HLA完全相合供者的白血病患者提供了新的治疗手段，但要特别注意移植后病毒和真菌感染的防治。

Clinical Study on Haploid HLA-Matched Peripheral Blood Stem Cell Transplantation in the Treatment of Acute Leukemia

Objective:To explore the efficiency and safety of haploid HLA-matched peripheral blood stem cell transplantation(PBSCT)in the treatment of acute leukemia.Methods:4 patients with acute leukemia were treated by PBSCT,including 2 acute lymphocytic leukemia,2 acute non-lymphocytic leukemia,all of whom were in complete remission.2 patients had HLA 1 and 2 locus mismatched.The other 2 patients both had HLA 3 locus mismatched.Conditioning regimen consisted of total body irradiation or Busulfan,Ara-c,Cyclophosphami...
