Abstract

目的探讨国产酪氨酸激酶抑制剂(TKI)达沙替尼(商品名:依尼舒)二线治疗慢性髓性白血病慢性期(CML-CP)患者的疗效及安全性。方法回顾性分析2016年3月至2018年7月湖北省CML协作组成员医院收治的二线服用国产达沙替尼的CML-CP患者的病例资料,统计患者治疗3、6和12个月时最佳反应率、累积完全细胞遗传学反应(CCyR)率、累积主要分子学反应(MMR)率、无进展生存(PFS)、无事件生存(EFS)情况及不良反应情况。结果共纳入83例CML-CP患者,中位随访时间为23(4~45)个月,达沙替尼治疗3、6、12个月最佳反应率分别为77.5%(54/71)、72.6%(61/75)、60.7%(51/69)。至随访截止,累积CCyR率、MMR率分别为65.5%(55/80)、57.1%(48/73),达CCyR和MMR的中位时间均为3个月。随访时间内,PFS率为94.0%(79/83),EFS率为77.4%(65/83)。国产达沙替尼最常见非血液学不良反应为水肿(32.5%),其次为皮疹瘙痒(18.1%)、乏力(13.3%),血液学不良反应主要有血小板减少(31.3%)、白细胞减少(19.3%)和贫血(6.0%)。结论国产达沙替尼二线治疗CML-CP患者具有较好的疗效及安全性,可作为CML-CP患者的治疗选择。
