Abstract:

【】 目的 探讨对自体造血干细胞移植(autologoushematopoieticstemcelltransplantation,auto-HSCT)后复发的非霍奇金淋巴瘤患者再进行异基因造血干细胞移植(allogeneichematopoieticstemcelltransplantation,allo-HSCT)治疗的临床疗效。 方法 收集2000年1月-2010年12月难治性恶性淋巴瘤采用auto-HSCT后复发患者11例,病程27个月~6.5年。所有患者在auto-HSCT前均为复发难治性病例,auto-HSCT后,完全缓解8例,部分缓解3例,自体移植后中位复发时间15个月,患者复发后采用异基因亲缘造血干细胞移植,人类白细胞抗原(humanleukocyteantigen,HLA)全相合(6/6)6例,5/6相合3例,4/6相合2例;性别相同6例,性别不同5例。预处理方案为FBC方案,即氟达拉滨30mg/m21~5d,白消安12~14mg/kg分4d口服,环磷酰胺120mg/kg分2d使用。移植物均为外周血造血干细胞加骨髓。移植物抗宿主病(graft-versus-hostdisease,GVHD)的预防HLA全相合采用环孢素+短程甲氨蝶呤+吗替麦考酚酯,不全相合采用抗胸腺细胞球蛋白+环孢素+短程甲氨蝶呤+吗替麦考酚酯。 结果 11例患者全部获得造血重建,急性GVHD发生6例(54.55%),其中Ⅰ度、Ⅱ度4例,Ⅲ度、Ⅳ度各1例;1例Ⅳ度GVHD因合并感染死亡,5例均得到有效控制;发生慢性GVHD7例(63.64%),其中有2例急性GVHD转为慢性,4例局限型,3例广泛型。随访8个月~9年,有4例分别于移植后8、15、21、34个月疾病复发,另外6例仍生存。 结论 allo-HSCT对于auto-HSCT后复发的非霍奇金淋巴瘤患者仍是一种有效的挽救性治疗手段。【Abstract】 Objective Toexploretheclinicalefficacyofallogeneichematopoieticstemcelltransplantation(allo-HSCT)onrelapsingnon-Hodgkin′slymphomaafterautologousstemcelltransplantation(auto-HSCT).
