摘 要:目的总结索拉非尼治疗伴FLT3-ITD突变急性髓系白血病(AML)的疗效,探讨该亚型急性白血病的有效疗法。方法回顾性分析2012年1月至2015年2月苏州大学附属第一医院以MICM分型(M、I、C、M分别代表细胞形态学、免疫学、细胞遗传学和分子遗传学)确诊的42例伴FLT3-ITD突变AML患者资料,其中32例为化疗后未缓解或复发,10例为异基因造血干细胞移植(allo-HSCT)后复发。前者给予索拉非尼或联合化疗再诱导治疗,后者给予索拉非尼或联合供体淋巴细胞输注或化疗再诱导治疗。化疗后未缓解或复发的32例患者中,13例后续桥接allo-HSCT治疗,其余19例给予索拉非尼或联合化疗巩固治疗。结果42例患者给予含索拉非尼方案再诱导治疗的总体有效率为73.8%,其中4例(9.5%)获得分子生物学完全缓解(CMR),9例(21.4%)获得完全缓解(CR),8例(19%)获得伴有不完全血液学恢复的完全缓解(CRi),10例(23.8%)获得部分缓解(PR),11例(26.2%)为未缓解(NR)。化疗后未缓解或复发的32例中,17例给予索拉非尼单药治疗,总体有效率为70.6%,而15例联合化疗患者的总体有效率为66.7%,两者差异无统计学意义(P=0.555)。13例后续桥接allo-HSCT治疗,其中移植前获得CMR/CR/Cri者共6例,PR者4例,NR者3例。42例患者的2年总生存(OS)率、无进展生存(PFS)率分别为36.9%、28.7%,中位OS、PFS时间分别为18和9个月;其中索拉非尼联合allo—HSCT治疗组与索拉非尼或联合化疗治疗组的2年OS率分别为45.5%和23.9%(P=0.041),2年PFS率分别为44.0%和9.7%(P=0.014),差异均有统计学意义。患者主要死亡原因是疾病复发进展(12例);另有4例死于感染,1例死于移植后慢性移植物抗宿主病。结论索拉非尼联合化疗能有效提高伴FLT3-ITD突变AML的诱导缓�Objective To analyze the efficacy of sorafenib on the treatment of patients diagnosed as acute myeloid leukemia(AML) with FLT3-ITD mutation. Methods From January 2012 to February 2015, 42 cases of AML with FLT3-ITD mutation according to MICM ( morphology, immunology, eytogeneties and molecular) diagnosis system in our hospital were retrospectively analyzed. Thirty-two cases were refractory to chemotherapy or relapsed, who were treated with sorafenib or combined with chemotherapy. Ten patients relapsed after allogeneic hematopoietic stem cell transplantation (allo-HSCT), who were retreated with sorafenib or combined with donor lymphocyte infusion (DLI) or chemotherapy. In the first group, 13 of 32patients accepted allo-HSCT. Results The overall response rate of all 42 patients was 73.8%, including 4 (9.5%) complete molecular remission (CMR), 9 (21.4%) complete remission (CR), 8 (19%) complete remission with incomplete hematologic recovery (CRi) , 10 (23.8%) partial remission (PR) , and 11 (26. 2% ) none remission (NR). The response rate of sorafenib alone for 17 patients was 70. 6% , and that of sorafenib plus chemotherapy was 66.7% (P = 0. 555 ). Thirteen patients who received allo-HSCT included 6 CMR/CR/CRi, 4 PR, and 3 NR before transplant. The 2-year overall survival (OS) rate and progress free survival (PFS) rate in all patients were 36. 9% and 28. 7%, and the corresponding median time were 18 months and 9 months respectively. The 2-year OS rate in 23 patients who received sorafenib combined with allo-HSCT was superior to that in 19 patients not receiving allo-HSCT (45.5% vs 23.9%, P =0. 041 ) , so was PFS rate (44.0% vs 9. 7% , P = 0. 014). Twelve cases died of disease progression, four of infection, and one of chronic graft versus host disease after transplant. Conclusions Sorafenib combined with chemotherapy improves response rate of AML patients with FLT3-ITD mutation. Those who are treated with sorafenib plus allo-HSCT obtain bet
