摘  要:目的分析伊马替尼治疗慢性粒细胞白血病(CML)的疗效和患者生存情况,并初步探讨影响伊马替尼疗效的因素。方法对2002年5月至2006年5月接受伊马替尼治疗的95例CML患者随访至2006年10月31日,分析患者的治疗转归及相关影响因素。结果①慢性期组伊马替尼治疗后12个月95.5%患者获得完全血液学缓解(CHR);其中遗传学资料完整的52例患者中初治19例,复治33例,初治组治疗后6、12、18、24、30个月的主要细胞遗传学缓解(MCyR)率分别为84.2%、84.2%、89.5%、89.5%和94.7%,复治组分别为36.4%、39.4%、39.4%、39.4%和39.4%,两组比较差异有统计学意义(P〈0.01);全组患者治疗后12、24、36、50个月预期生存率分别为(98.1±1.9)%、(87.8±7.1)%、(81.9±8.7)%和(81.9±8.7)%。②加速期组伊马替尼治疗后12个月70%患者获得CHR,10%获得MCyR;治疗后12、24和36个月预期生存率分别为(63.0±17.7)%、(15.8±14.3)%和(15.8±14.3)%。③急变期组伊马替尼治疗后6个月57.9%患者获得CHR;治疗后12、24个月预期生存率分别为(40.6±12.3)%和0。④对慢性期组进行COX多因素预后分析显示,伊马替尼治疗前有无其他治疗是影响无进展生存和获得MCyR的独立预后不良因素。结论①伊马替尼作为一线治疗药物用于CML慢性期,对患者生存质量的改善明显优于作为替换治疗药物或用于加速、急变期治疗,因此伊马替尼应明确作为首选的一线治疗药物。②伊马替尼治疗加速期和急变期CML也能获得一定血液学、遗传学疗效,延长患者生存期。Objective To investigate the efficacy of imatinib in the treatment of chronic myeloid leukemia (CML) and analyse the treatment outcome and related factors. Methods Ninety five CML patients were treated with imatinib in our hospital from May 2002 to May 2006. The outcomes and related factors were analysed. Results (1)One year after therapy, there were 95.5% of chronic phase(CP) patients achieved complete hematologic response (CHR). Fifty-two patients with complete cytogenetic dates were divided into primary-therapy group (n = 19 ) and secondary-therapy group (n = 33 ). The major cytogenetic responses (MCyR) at 6-, 12-, 18-,24- and 30-months after therapy for the former group were 84.2%, 84. 2%, 89.5%, 89.5% and 94.7% , and for the latter group were 36.4% , 39.4%, 39.4%, 39.4% and 39.4%, respectively ( P 〈0. 01 ). The expected survival at 12-, 24- ,36- and 50-month after imatinib treatment for CP group was ( 98.1 ± 1.9) % , ( 87.8 ± 7.1 ) % , ( 81.9 ± 8.7 ) % and ( 81.9 ± 8.7 ) %, respectively. (2)Twelve month after therapy, there are 70% of accelerated phase(AP) patients achieve CHR and 10% get MCyR. The expected survival at 12-, 24- and 36-month after imatinib treatment for AP group was ( 63.0 ± 17.7 ) % , ( 15.8 ± 14.3 ) % and ( 15.8 ± 14.3 ) % , respectively. (3)Six month after therapy, 57.9% of blast crisis (BC) patients achieve CHR, with the expected survival at 12- and 24-month of (40.6 ± 12.3 ) % and 0, respectively. (4)COX analysis CP group indicated that imatinib therapy administered for previously untreated was an independent favorable prognostic factor. Conclusion (1) Imatinib as a primary treatment for CP CML can significantly improve the survival time as compared with that AP or BC patients or with that used in previously treated patients. (2) Imatinib could induce hematologic, even cytogenetic response to a certain extent, in CP or BC patients and prolong the survival time.
