摘 要:目的评价BDHALL2000/02方案治疗60岁以下成人Ph染色体/BCR—ABL融合基因阳性(简称Ph+)急性淋巴细胞白血病(ALL)的疗效,并比较分析不同亚组的治疗结果。方法2001年1月至2011年6月就诊的42例成人Ph+ALL(年龄15—60岁)患者纳入前瞻性、非随机BDHALL2000/02方案临床研究。患者接受标准VDCP±L±伊马替尼(IM)诱导治疗,缓解后予以改良Hyper—CVAD/MA方案强化巩固,有合适供者的患者在第1次完全缓解(CR,)期行异基因造血干细胞移植(allo—HSCT)。无合适供者的患者序贯强化巩固治疗±IM,获得分子生物学缓解(MCR)者可选择接受自体造血干细胞移植(ASCT),ASCT后接受2年MM4-VP±IM维持治疗;其他患者继续完成再诱导、巩固、维持治疗。分析患者的无病生存(DFS)、总生存(OS)情况和复发率(RR)。结果39例(92.9%)患者获得CR,其中1个疗程CR率为83.3%。随访至2012年4月30日,28例规范治疗的患者,中位随访26.5(8~75)个月,DFS期和0s期分别为(22.0±3.5)和(37.0±5.3)个月,累积RR率为(43.7±9.7)%。化疗组7例均复发;ASCT组5例中3例移植前后未使用IM者在移植后1年内均复发,另2例应用IM者持续MCR已达移植后35和12个月;allo—HSCT组16例中移植相关死亡2例,5例复发;allo—HSCT、ASCT和化疗组中位0s期分别为未达到、22和14个月,预期3年0s率分别为(66.7±12.2)%、(25.0±21.7)%和(16.74-15.2)%(P=0.014);三组的中位DFS期分别为未达到、24和10个月(P=0.002),预期3年DFS率分别为(56.3±12.4)%、(26.7±22.6)%和0(P=0.002)。结论IM联合化疗及Hyper—CVAD/MA强化治疗可提高Ph+ALL患者缓解率和缓解质量,增加移植的可行性。allo-I-/SCT仍然是年轻、有合适供者患者的首选治疗方法。对于无合适供者获得MCR的患者,ASCT�Objective To explore the treatment options for younger than 60 years old adults with Ph /BCR-ABL positive acute lymphoblastie leukemia (Ph + ALL). Methods From January 2001 to June 2012, 42 adult patients were enrolled in the study. All patients received standard VDCP±L + imatinb(IM) as induction therapy followed by intensive consolidation of modified Hyper-CVAD/MA±IM. At complete remission 1 ( CR1 ) , patients with appropriate donor received allogeneic hematopoietic stem cell transplantation ( allo- HSCT) , the others sequentially received intensive consolidation ±IM and autologous HSCT (ASCT) at mo- lecular CR( MCR), then MM -+ VP _+ IM as maintenance therapy. Overall survival ( OS), disease free survival (DFS) and relapse rate (RR) were analyzed. Results CR rate after 1 cycle of induction chemotherapy was 83.3%. 39 (92.9%) patients achieved CR. The median DFS and OS were (22.0± 3.5) and (37.0±5.3) months respectively, with cumulative RR of (43.7±9.7) % during a median follow-up of 26.5 (8 - 75 ) months. All 7 patients in CT group relapsed. Two patients received IM pre- and post-ASCT maintained MCR for 35 and 12 months after ASCT. But the other 3 ASCT recipients without IM died of relapse within 1 year. The transplant-related mortality rate in allo-HSCT group was 12.5%. The estimated 3-year OS in allo- HSCT (n=16), ASCT (n=5) and CT (n=7) groups were (66.7±12.2) %, (25.0±21.7)% and (16.7±15.2)% , respectively (P = 0. 014) ; meanwhile, the estimated 3-year DFS in those groups were of (56.3±12.4) %, ( 26.7±22.6) % and 0, respectively ( P = 0.002). Conclusion IM combined with in- tensive chemotherapy significantly increased the CR rate with the improved quality of CR, whieh highlighted the feasibility of SCT. Allo-HSCT could decrease relapse to produce favorable OS and DFS in CR1 of young a- dults with Ph + ALL. ASCT combined IM might be the treatment of choice for those achieved MCR but without don
