 【摘要】 目的 探讨急性白血病异基因造血干细胞移植(allo-HSCT)后髓外复发的临床特点及疗效。方法 分析1例急性髓系白血病(AML-M2)及1例急性淋巴细胞白血病(B-ALL)患者行allo-HSCT后髓外复发的临床、实验室特征,并结合文献分析白血病allo-HSCT后髓外复发的发病机制、危险因素、治疗方法及临床转归。结果 白血病allo-HSCT后髓外复发部位不一,髓外复发后绝大多数患者会发生骨髓复发,预处理方案、移植物抗白血病/移植物抗宿主病的程度、白血病分型、移植时疾病状态、移植前髓外浸润、细胞遗传学的改变、白血病细胞的抗原表达等因素与移植后髓外复发有一定关系。对于白血病移植后髓外复发的治疗目前主张联合治疗,但疗效欠佳。结论 急性白血病allo-HSCT后髓外复发的发生率虽低,但治疗效果差,死亡率高,联合治疗有望能提高疗效。  相似文献

Objective: To analyze long-term outcome in sixty leukemia patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT) following busulfan and cyclophosphamide (BU-CY2) between 1994 and 2000.Methods: BU-CY2 was used as the conditioning regimen and allo-HSCT was performed for all patients. All the patients were followed-up until August 2001 or death. The leukemia-free survival, relapse and transplant-related mortality were discussed. Results: All 60 patients had sustained engraftment. Acute GVHD occurred in 22 out of 60 patients (36.7%), and the incidence of acute GVHD was 48% in the patients with CML, 30% in AML and 26.7% in ALL. 38 patients are still alive in continuous remission with a median follow-up of 30 months (range 12-84) and 22 patients have died. The main causes of death were acute GVHD in 3 patients, CMV-IP in 7 patients and relapse in 11 patients,the remaining one died of pulmonary infection. Among 11 patients who died of relapse, 8 patients with ALL relapsed in the early stage post transplant (8115, 53.3%), relapse was observed in the remaining 3 patients with AML, and however, no relapse was observed in CML. The probability of disease-free survival at 3 years for CML. AML and ALL patients was 80%, 70% and 26.7%, respectively.Conclusion: This results suggests that BU-CY2 is an effective conditioning regimen in patients with AML and CML, resulting in a low relapse rate and high long-term survival rate, but not as effective in patients with ALL, with a higher incidence of relapse and therefore, not recommended for ALL patients.  相似文献

Objective: To explore the influence of omission of the day 11 dose of methotrexate (MIX) on the incidence and severity of graft-versus-host disease(GVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT). Methods: From April 1997 to October 2002, 80 leukemia patients (46 men and 34 women aged from 12 to 56 years with a median age of 35) underwent allo-HSCT at our BMT unit. Among them, 58 patients received grafts from HLA-identical siblings, 8 from HLA one major antigen mismatched siblings and 14 from HLA-matched unrelated donors.All patients received a modified cyclosporine and short-course MTX regimen for GVHD prophylaxis,which included MTX 15 mg on day 1, and 10 mg on days 3 and 6 (MTX day 11 dose omitted) and cyclosporine given daily. Results: The overall incidence of grade Ⅰ-Ⅳ acute GVHD was 57.5% (46/80 patients), with grade Ⅱ-Ⅳ acute GVHD in 28 patients(35%) and grade Ⅲ-Ⅳ acute GVHD in 7 patients(8.8%). Among 58 patients receiving grafts from HLA-identical siblings, 24 patients developed grade Ⅰ-Ⅳ acute GVHD (41.4%), with grade Ⅱ-Ⅳ acute GVHD in 13 patients (22.4%) and grade Ⅲ-Ⅳ acute GVHD in 4 patients (6.9%). 21 out of 22 patients receiving grafts from HLA one major antigen mismatched siblings and HLA-matched unrelated donors developed grade Ⅰ-Ⅳ acute GVHD (95.5%),with grade Ⅱ-Ⅳ acute GVHD in 14 patients (63.6%)and grade Ⅲ-Ⅳ acute GVHD in 3 patients (13.6%).Chronic GVHD occurred in 38 out of 56 evaluable patients (67.9%), with extensive form in 15 patients(26.8%) and limited form in 23 patients (41.1%). With a median follow-up of 960 days (range 180-1980 days), the probability of leukemia-free survival at 3 years was 61.3% for all patients. Conclusion: Our results suggest that the day 11 MTX can be omitted without a major deleterious effect on the incidence and severity of graft-versus-host disease after HLA-identical sibling transplantation as well as HLA one major antigen mismatched sibling and HLA-matched unrelated donor transplantation.  相似文献

During the past 10 years, 86 patients 30 to 54 years of age with hematologic malignancies were prepared with high-dose radiochemotherapy and received histocompatible bone marrow grafts. Thirty-four of these patients are surviving for 4 months to 9 years (median, 26 months) following marrow transplantation and 32 of them are in continuing complete remission (CR). Disease-free survival is 44% for 37 patients who were in first remission of acute leukemia or in the chronic phase of chronic granulocytic leukemia (CGL), 23% for 39 patients whose leukemia had relapsed at least once before transplantation or who had advanced stages of CGL, and 60% for ten patients who had hematologic malignancies other than leukemia. The median age of the surviving 34 patients is 36 years (range, 30 to 43 years). The incidence of moderate to severe acute graft-v-host disease (GVHD) was 48% and of chronic GVHD, 26%. The major causes of failure were interstitial pneumonia in 31 patients (24 of whom had antecedent acute GVHD) and recurrent leukemia in 12 patients (11 of whom had either never entered a CR or had relapsed at least once with acute leukemia or had progressive CGL before transplantation). Our data warrant further prospective studies in patients with hematologic malignancies who are older than 30 years.  相似文献

Of 455 acute nonlymphocytic leukemia (ANL) patients who underwent marrow transplantation, 95 (21%) relapsed a median of 6.5 months posttransplantation and 62 received further treatment. Twenty achieved remission. Success of therapy was related to the length of time from marrow transplant to relapse and to the use of cytarabine (Ara-C) and daunomycin. Aggressive chemotherapy for patients relapsing within 100 days of marrow transplant was associated with a high incidence of early death (six of 14 patients) and a low probability of remission (one of 14). Of 23 patients who relapsed in excess of 1 year from marrow transplant, 15 achieved a complete remission. The median disease-free survival is 6 months (range, 0.4 to 53+ months). Acute lymphocytic leukemia (ALL) recurred in 130 of 366 patients (36%), and 94 received further therapy. Fifty-two achieved a remission. Remissions were more common in late relapse patients (greater than 1 year from transplantation): 65% v 7% for those relapsing within 100 days from transplant (P less than .05). Testicular relapse occurred in 11 patients and was the sole site of relapse in seven. Three are alive and free of disease 58 to 109+ months after relapse. The median survival for the treated patients is 10.5 months (range, 5 to 109+ months). We propose that reinduction be attempted in all patients relapsing greater than 1 year from marrow transplantation. Ara-C and daunomycin should be employed in the treatment of ANL. The decision for treatment of patients relapsing earlier than 1 year should be made on an individual basis.  相似文献
