NEJM:伊马替尼加聚乙二醇干扰素α-2a 在慢性髓系白血病中的疗效

2010-12-29 MedSci原创 MedSci原创

  背景 对于新近被诊断为慢性髓系白血病(CML)慢性期的病人,伊马替尼(400 mg/d)被认为是最佳的初始疗法。然而,仅少数接受伊马替尼治疗的病人有完全的分子学缓解。   方法 我们将636例未经治疗的慢性期CML病人随机分为4组:第一组仅接受剂量为400 mg/d的伊马替尼治疗,第二组接受伊马替尼(400 mg/d)加阿糖胞苷(每日20 mg/m2体表面积,在每个为期28天的疗程中的第1

  背景 对于新近被诊断为慢性髓系白血病(CML)慢性期的病人,伊马替尼(400 mg/d)被认为是最佳的初始疗法。然而,仅少数接受伊马替尼治疗的病人有完全的分子学缓解。

  方法 我们将636例未经治疗的慢性期CML病人随机分为4组:第一组仅接受剂量为400 mg/d的伊马替尼治疗,第二组接受伊马替尼(400 mg/d)加阿糖胞苷(每日20 mg/m2体表面积,在每个为期28天的疗程中的第15~28天给药)治疗,第三组接受伊马替尼(400 mg/d)加聚乙二醇干扰素α-2a(90 μg/w),第四组仅接受剂量为600 mg/d的伊马替尼治疗。我们评估了分子学和细胞遗传学疗效反应、到治疗失败的时间、总生存和无事件生存情况,以及不良事件。我们计划在12个月时进行一次分子学疗效反应的分析。优良的分子学疗效反应被定义为酪氨酸激酶基因BCR-ABL转录物与ABL转录物之比下降≤0.01%,对应于较基线水平下降 ≥4 log10单位(用实时定量聚合酶链反应测定法评估)。

  结果 12个月时,4组之间的细胞遗传学有效率相似。在接受伊马替尼加聚乙二醇干扰素α-2a治疗的病人(30%)中,优良的分子学有效率显著高于仅接受400 mg伊马替尼的病人(14%)(P=0.001)。在接受治疗超过12个月的病人中,该有效率显著高于接受治疗≤12个月者。在接受阿糖胞苷治疗的病人中,胃肠事件较常见, 而在接受聚乙二醇干扰素α-2a的病人中,皮疹和抑郁症较常见。

  结论 在有慢性期CML的病人中,与其他治疗相比,在伊马替尼治疗基础上增加聚乙二醇干扰素α-2a,导致了显著较高的分子学有效率。
