摘  要:目的评价异基因造血干细胞移植(allo_HSCT)治疗重型再生障碍性贫血(SAA)患者的疗效。方法回顾性分析单中心2003年1月至2012年12月接受alIo_HSCT的70例SAA患者的临床资料。其中男性40例,女性30例,患者中位年龄为20岁(5-41岁)。51例接受HLA匹配同胞供者allo-HSCT(MSDallo-HSCT),其中20例行骨髓移植(BMT),输注CD34+细胞中位数为3.46×106/kg;31例行外周血干细胞移植(PBSCT),输注CD34+细胞中位数为3.22×106/kg。19例接受替代供者allo-HSCT(ADallo-HSCT),其中10例行BMT,输注CD34+细胞中位数为3.10×106/kg;9例行PBSCT,输注CD34’细胞中位数为4.90×106/kg。结果70例移植后均获得造血重建,中位随访时间为35.5个月(1~119个月),预期5年总体存活率(0s)为(79.0±5.1)0A。51例MSDallo-HSCT受者移植后15例发生急性移植物抗宿主病(GVHD),10例发生慢性GVHD,6例发生移植物排斥反应;51例中死亡7例,5年OS为(85.0±5.4)%。19例ADallo-HSCT受者移植后12例发生急性GVHD,7例发生慢性GVHD,1例发生移植物排斥反应;19例中死亡7例,5年OS为(63.2±11.1)%。多因素分析结果显示:行PBSCT(P=0.049)、移植后发生严重(II~Ⅳ度)急性GVHD(P=0.025)、严重感染(侵袭性真菌病或巨细胞病毒)(P=0.05)显著降低SAA患者allo-HSCT后疗效。结论Allo-HSCT是治疗sAA患者的有效手段,尤其MSDallo-HSCT疗效显著,但在无HLA匹配同胞供者的SAA患者中也可选择ADallo-HSCT作为替代治疗。采用BMT能有效预防移植后严重(II~Ⅳ度)急性GVHD及严重感染(侵袭性真菌病或巨细胞病毒),对于提高SAA患者allo-HSCl了宁效至关重要。Objective To evaluate the efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for severe aplastic anemia (SAA). Method The clinical data of 70 cases of SAA receiving allo-HSCT from January 2003 to February 2012 were retrospectively analyzed. There ere 40 males and 30 females with median age of 20 (5-41) years old. Fifty-one patients received HLA-matched sibling donor (MSD) allo-HSCT, and 19 patients received alternative donor(AD) alIo- HSCT. Of 51 patients receiving MSD allo-HSCT, 20 patients were subjected to bone marrow transplantation (BMT), and 31 patients to peripheral blood stem cell transplantation (PBSCT). The median reinfusion quantity of CD34+ was 3. 46 (2. 00-4. 80) × 106/kg in BMT, and 3. 22 (1.27- 5.98) ×106/kg in PBSCT. Of patients receiving AD allo-HSCT, 10 patients were subjected to BMT, and 9 to PBSCT. The median reinfusion quantity of CD34+ was 3. 10 (2. 11 -4. 38)× 106/kg in BMT, and 4. 90 (2. 08- 6. 88) ×106/kg in PBSCT. Result Hematopoiesis reconstitution was achieved in all 70 patients, median follow-up time was 35.5 (1-119) months, and prospective overall survival (OS) for 5 years was (79. 0 ± 5.1) %. Of the patients receiving MSD allo-HSCT, acute graft- versus-host disease (aGVHD) occurred 16 cases, chronic GVHD (cGVHD) in 10 cases, and graft rejection (GR) in 6 cases. There were 7 deaths. OS for 5 years was (85.0± 5.4)%. In the patients receiving AD allo-HSCT, aGVHD occurred in 12 cases, cGVHD in 7 cases, and GR in one case. There were 7 deaths. OS for 5 years was (63.2 ± 11.1)%. Multiplicity analysis revealed that PBSCT (P= 0. 049), severe ([I-IV) aGVHD (P = 0. 025) and severe infection (invasive fungal disease or cytomegalovirus) (P = 0. 05) could reduce the efficacy of allo-HSCT for SAA significantly. Conclusion Allo-HSCT is an effective therapy for patients with SAA, especially those receiving MSD allo-HSCT. AD allo-HSCT might be feasible for SAA patients
