摘要
目的探讨二代酪氨酸激酶抑制剂（TK-Ⅱ）联合异基因造血干细胞移植（allo-HSCT）治疗高危Ph染色体阳性（Ph＋）白血病的疗效及安全性。方法对17例行allo-HSCT的高危Ph＋白血病患者进行回顾性分析，其中慢性髓性白血病（cML）8例（加速期1例、急变期7例），Ph＋急性淋巴细胞白血病（Ph＋ALL）9例。在allo-HSCT前后给予尼洛替尼或达沙替尼治疗，观察疗效及不良反应。结果所有患者均成功植人，粒系重建的中位时间为12（10～14）d，巨核系重建的中位时间为15（11～23）d。7例患者发生急性移植物抗宿主病（GvHD），其中I～Ⅱ度6例，Ⅲ度1例；6例发生慢性GVHD，均为局限型；无致死性GVHD发生。17例患者中位随访时间为17（3～60）个月，11例无病生存，6例复发，其中5例死亡。结论TK-Ⅱ联合allo-HSCT可有效提高高危Ph＋白血病患者的缓解率，减少allo-HSCT后复发，从而有助于提高高危Ph’白血病的治疗成功率。
Objective To investigate the efficacy and safety of second-generation tyrosine kinase inhibitors （TK- II ） combined with allogeneic hematopoietic stem cell transplantation （allo-HSCT） in the treatment of high-risk Philadelphia chromosome positive （Ph＋） leukemia. Methods The clinical data of 17 cases of high-risk Ph＋ leukemia patients underwent allo-HSCT were retrospectively analyzed, including 1 case in accelerated phase and 7 cases in blast crises of chronic myeloid leukemia, and 9 cases of Ph＋ acute lymphoblastic leukemia. Nilotinib or Dasatinib were aderministrated before and （or） after allo-HSCT in all patients. Results All patients successfully engrafted. Median times to neutrophil and platelet recovery were 12 days （range 10-14） and 15 days （range 11-23）, respectively. Acute GVHD developed in 7 patients： 6 patient had grade 1 to 2 and 1 patient grade 3. Chronic GVHD developed in 6 patients, all were limited and no lethal GVHD occurred. At a median follow-up of 17 （range 3-60） months, 11 （64.7%） patients survived disease free, 6 patients relapsed and 5 died. Conclusion TK- 1I combined with allo- HSCT effectively improved the remission rate of high-risk Ph~ leukemia and reduced recurrence after allo- HSCT, which represented an important improvement in the treatment of patients with high-risk Ph ~ leukemia.
