目的分析4711份库存脐血造血细胞含量及探讨脐血造血细胞含量与白血病脐血移植疗效的关系。方法分析4711例库存脐血总有核细胞数(TNC)和CD34+细胞数分布情况,探讨不同的造血细胞输入量、供受者HLA不相合数、受者性别、年龄、体重和疾病类型间植入率和生存率的差异。结果 4711例库存脐血TNC和CD34+细胞中位数分别为1.14×109/kg和4.06×106/kg,按3.7×107/kg有效TNC输入量计算,93.2%脐血可供体重50 kg以下受者移植。89例白血病患者移植后植入75例,植入率为84.3%。中性粒细胞绝对值≥0.5×109/L、血小板≥20×109/L和≥50×109/L的时间分别为移植后17、34和46 d。75例植入病例中,长期无病存活47例,死亡26例,2例复发;急性移植物抗宿主病(GVHD)Ⅰ~Ⅱ度、Ⅲ~Ⅳ度和慢性GVHD发生率分别为54.7%、20.0%、9.3%。影响移植植入率的因素包括受者年龄、TNC和CD34+细胞输入量;影响生存率的因素包括受者年龄、体重和输入CD34+细胞数。结论在无法找到HLA全相合骨髓供者时,可选择脐血作为替代骨髓的造血干细胞来源治疗儿童与成人白血病,TNC和CD34+细胞数仍是选择脐血移植物的参考指标。 相似文献

Abstract: We reviewed 26 consecutive patients with AML who were transplanted in second CR2 between 1994 and 2005. The most common conditioning regimen was CY and TBI. Median age at transplant was 8.9 yr (range 2.2–18.2). Nine patients received related donor, 16 patients received unrelated donors, and one patient received unrelated cord stem cells. Acute grade III–IV and chronic extensive GVHD occurred in eight (30%) and nine (35%) patients, respectively. Six patients (23%) relapsed, four of them died. Six patients (23%) died from TRM. Estimate of three‐yr EFS was 0.53 (95% CI; 0.34–0.72). Including the two relapsed patients who were salvaged by DLI and second transplantation, three‐yr OS was 0.61 (95% CI; 0.41–0.78) with a median follow‐up of three and a half yr (range 1.5–11.2 yr). When entering remission, children with relapsed AML have a reasonable survival with HSCT, but relapse and TRM remain a concern. 相似文献

目的:目前仅有30%左右的重型β-地中海贫血患者能找到HLA全相合的同胞供者,使造血干细胞移植治疗该病受到限制。该研究通过探讨单倍体造血干细胞移植治疗儿童重型β-地中海贫血的疗效,希望能够拓展供者源。方法:采用单倍体脐血或骨髓对10例重型β-地中海贫血患儿进行11例次移植。使用以羟基脲、氟达拉滨、白消安、环磷酰胺、抗胸腺细胞球蛋白为基础的预处理方案。结果:6例患者获长期稳定植入并脱离红细胞输注;2例短暂植入后排斥,其中1例恢复地中海贫血状态,另1例在移植早期死亡;1例行2次移植均未植入并出现移植后再障;1例未植入,出现再障,1年后恢复地中海贫血状态。8例植入者均发生急性移植物抗宿主病,仅1例发展为皮肤局限性慢性移植物抗宿主病。随访57.1(2.5~85.1)月,总体生存率90%,无病生存率为60%。结论:单倍体造血干细胞移植治疗儿童重型β-地中海贫血能长期重建造血,在无HLA相合同胞供体时,可以作为造血干细胞移植治疗的一种选择。[中国当代儿科杂志,2009,11(7):546-548] 相似文献

The authors examined data from 166 children who received autologous peripheral blood progenitor cell (PBPC) transplantation to ascertain the incidence of early transplant-related mortality (TRM) and the contributing risk factors. Eleven patients (6.6%) (6 boys, 5 girls) died within 180 days following PBPC infusion. The median age was 4 years (range 2-17). The overall probability of TRM was 6.9 +/- 2% at day +180. On univariate analysis, the status of disease at transplantation (complete remission vs. not in complete remission) was identified as the only pretransplant significant predicting factor for TRM (14% of patients who were not in complete remission died within 180 days after PBPC infusion, whereas only 2% of patients in complete remission died) (relative risk [RR] 1.13, 95% confidence interval [CI] 1.01-1.26, P = 0.01). Age, gender, conditioning, and number of CD34+ cells infused were not significantly associated with TRM. In the postinfusion phase, patients who developed multiorgan dysfunction during the neutropenic period, especially when the lung was the first failing organ (RR 16.1, 95% CI 7.16-36.18, P = 0.0001), and those with engraftment syndrome (RR 2.81, 95% CI 1.49-5.24, P = 0.001) had an increased risk for TRM. On multivariate analysis, development of engraftment syndrome was the only significant variable that influenced TRM. In conclusion, the authors found for the first time that engraftment syndrome emerges as the main cause of TRM after autologous PBPC transplantation in children with malignancies. 相似文献

To investigate which factors impact on survival, relapse, relapse free survival, transplant-related mortality (TRM) and graft-versus-host disease (GVHD) in children who undergo allogeneic stem cell transplantation, we included all 181 children transplanted due to leukemia at our unit. At the end of follow up 54% of the patients were alive, 27% had died due to relapse while 19% had died of other causes. Survival was similar in recipients of related (55%) and unrelated grafts (48%). Risk factors identified in univariate analysis were brought into a multivariable analysis. However, an unrelated donor was not identified as a risk factor for any of the five end-points analysed. A donor positive for three to four herpes viruses increased the risk of acute GVHD, TRM and death. A female to male transplant increased the risk of TRM, particularly if combined with a mismatch. Early stage of disease as well as human leukocyte antigen (HLA)-matching independently predicted survival. The risk of relapse increased after 1992. Chronic GVHD independently decreased the risk of relapse (relative risk RR, 0.39) and death (RR 0.42). We conclude that in children with leukemia other specific donor characteristics such as HLA-matching, gender, parity, and exposure to herpes viruses were more important for outcome than relationship. 相似文献

OBJECTIVES: Transplant results for Fanconi anemia with alternative-donor bone marrow transplantation currently entail a high incidence of graft failure and graft-versus-host disease (GVHD). The authors sought to improve outcome in this disease category with alternative donors with a 5-6/6 antigen match by transplantation of highly purified peripheral blood progenitor cells (PBPC) using the Isolex 300i v2.5 device as a means of T-cell depletion to lessen the risk of GVHD. METHODS: All Fanconi anemia patients (n = 8) received the same preparative regimen that included total body irradiation (450 cGy), Cytoxan (20 mg/kg), ATGAM, and fludarabine (120 mg/m2). The cell dose of CD34+ cells was a median of 11.4 x 10(6)/kg; the cell dose of CD3+ cells was a median of 1.9 x 10(4)/kg. Primary engraftment was rapid in all patients, with neutrophil recovery occurring at a median of day 10 and platelet count more than 50,000 on day 27. Two patients subsequently had secondary graft failure. Despite lack of cyclosporine GVHD prophylaxis, only two patients developed acute GVHD (both grade I), and no patients developed chronic GVHD. Three patients died: one at day 59 secondary to disseminated fungal infection, the second at day 196 during a second transplant, and the third at day 202 due to graft failure. With a median follow-up of 12 months, the overall survival was 58 +/- 18%. CONCLUSIONS: Transplantation of CD34-selected PBPCs from alternative donors results in a very low risk of GVHD in patients with Fanconi anemia. 相似文献

The authors compared the outcome in 100 children (61 boys, 39 girls; median age of 10.1 ± 3.4 years) with aplastic anemia who underwent either immunosuppressive therapy (IST; n = 70) or hematopoietic stem cell transplantation (HSCT; n = 30) between 1998 and 2007. Conditioning regimes for HSCT were a combination of either cyclophosphamide (Cy) with antilymphocyte globulin (ALG) or fludarabine (Flu) with Cy or busulfan (Bu) ± antithymocyte globulin (ATG). Stem cell source was bone marrow in 20 and peripheral blood stem cells (PBSCs) in 10. Patients undergoing IST received either equine ALG or ATG in combination with steroids and cyclosporine. Primary engraftment was seen in 25 children (83.3%), with acute graft-versus-host disease (aGvHD) in 5 (16.6%). The day 100 transplant-related mortality (TRM) was 30% and at a median follow up of 36 months (range: 6–197), the overall and disease-free survival is 70%. Among children who received IST, 60 children received ALG while 10 received ATGAM. Responses were seen in 27 children (43.5%), which was complete (CR) in 12 and partial (PR) in 15. At a median follow up of 38 months (range: 1–84), the overall survival is 37.1%, with 81.4% survival among responders and <10% survival among non-responders. HSCT would be the treatment of choice in children with severe aplastic anemia who have a human leukocyte antigen (HLA)-matched related donor and is superior to IST in this series from India. 相似文献

目的:研究异基因造血干细胞移植(allogeneic hematopoietic stem cell transplantation, allo-HSCT)治疗儿童慢性粒细胞性白血病(chronic myelogenous leukemia, CML)的治疗效果,寻找可能的影响因素,以期改善患者预后。方法:对接受allo-HSCT治疗的20例儿童CML患者,分别从年龄、性别、诊断至移植间隔时间、供受体HLA配型相合情况、移植时患儿疾病状态以及急慢性移植物抗宿主病(gost-v-host disease, GVHD)等多种因素进行疗效分析。结果:截止至随访日期,20例患者中,13例无病存活,7例死亡,其中4例死于急性重度GVHD,2例死于慢性GVHD及其并发症,1例死于移植后复发,3年总无病生存率为(64.6±1.1%)。单因素分析显示年龄是影响儿童CML治疗预后最重要的因素之一(P0.05)。多因素logistic回归分析也进一步证明仅年龄是影响预后的因素(P<0.01)。各种严重急慢性 GVHD是引起患者死亡最重要的原因。选择10位点全相合的供体进行移植治疗预后好。结论:allo-HSCT能有效治疗儿童CML,对于年龄≥10岁的CML患儿宜早期行allo-HSCT移植治疗,且尽可能选择10位点全相合的供体进行移植,积极防治GVHD,改善CML患儿移植治疗后的转归。 相似文献
