AM L行异基因造血干细胞移植后复发应用 FLAG方案联合G-DLI的疗效研究

目的：观察急性髓系白血病（AML）行异基因造血干细胞移植（allo‐HSCT）后血液学复发，应用FLAG方案联合粒细胞集落刺激因子动员的供者淋巴细胞输注（G‐DLI）治疗的临床疗效。方法对于接受异基因外周血造血干细胞移植（allo‐PB‐SCT）后复发的患者，给予FLAG方案化疗后在白细胞降至最低点时给予G‐DLI ，观察白血病缓解及生存情况，并通过 PubMed等检索进行文献复习。结果3例移植术后复发接受FLAG方案联合G‐DLI治疗者均再次获得完全缓解（CR）。1例G‐DLI后无病存活（DFS）13个月，后出现中枢复发，但骨髓一直处于缓解状态，23个月后因多脏器功能衰竭死亡，总生存（OS）为23个月。G‐DLI后发生皮肤Ⅱ度急性高移植物抗宿主病（GVHD）及肝脏Ⅰ度急性GVHD ，经处理后控制，未发生慢性GVHD。1例G‐DLI后12个月再次骨髓复发，放弃治疗于1个月后死亡，DFS及OS分别为12、13个月。G‐DLI后发生局限性皮肤慢性GVHD ，给予小剂量免疫抑制剂后得到控制。1例G‐DLI后无病存活至今，DFS为16个月。G‐DLI后发生局限性皮肤慢性GVHD ，给予小剂量免疫抑制剂后得到控制。结论 FLAG方案联合G‐DLI可能是AML行allo‐HSCT术后复发的有效治疗方式之一。

Observation curative effect of FLAG combination G-DLI for relapse of AML after allogeneic hematopoietic stem cell transplantation

Objective To observe clinical curative effect of the FLAG regimen combined donor lymphocyte infusion after granulocyte colony stimulating factor(G‐CSF) mobilization(G‐DLI) ,for the acute myeloid leukemia (AML) of allogeneic Peripheral blood hematopoietic stem cell trans‐plantation (allo‐HSCT) after recurrence of hematology .Methods For the patients with recur‐rence after allo‐HSCT ,giving the FLAG regimen chemotherapy when the WBC dropped to the lowest point ,followed by giving G‐DLI that infusion peripheral blood stem cell from the original donors ,to observe curative effect and survival situation .And searched the literature review through the PubMed etc .Results Through FLAG regimen combined G‐DLI ,3 cases of relapse after transplan‐tation again obtained complete remission (CR) .Case 1 :disease‐free survival (DFS) was 13 month and overall survival(OS) was 23 months after G‐DLI .The patient has been the central recurrence and remission in bone marrow ,he was dead after 23 months due to multipleorgan function failure .He occurred Ⅱ acute GVHD in Skin and Ⅰ acute GVHD in liver after G‐DLI and obtained effective control ,not chronic GVHD .Case 2 :DFS and OS were 12 months and 13 months ,as bone marrow relapse again and giving up treat‐ment ,so died a month later .Respectively ,he has limitations chronic GVHD in skin after G‐DLI .Case 3:DFS was 16 months after G‐DLI since the disease‐free survival ,had limitations GVHD in skin that was control for given small dose of immunosuppressive drugs .Conclusion Joint FLAG scheme and G‐DLI may be one of the effective treatment of postoperative recurrence of allo‐HSCT .
