ASCO 2011: 氨柔比星二线治疗小细胞肺癌优于托泊替康

2011-06-20 MedSci原创 MedSci原创

 ASCO 2011报道:Jotte等的一项研究报告表明,氨柔比星(AMR)二线治疗小细胞肺癌(SCLC)有活性,与托泊替康(Topo)相比,可显著改善缓解率(RR)。AMR组生存期较长[危险比(HR)为0.88],难治性患者亚组更是如此(HR为0.77)。   AMR是一种第三代蒽环类抗生素和强有力的DNA拓扑异构酶Ⅱ抑制剂,有望用于治疗SCLC。ACT-1研究对比了AMR和Topo二线治疗

 ASCO 2011报道:Jotte等的一项研究报告表明,氨柔比星(AMR)二线治疗小细胞肺癌(SCLC)有活性,与托泊替康(Topo)相比,可显著改善缓解率(RR)。AMR组生存期较长[危险比(HR)为0.88],难治性患者亚组更是如此(HR为0.77)。

  AMR是一种第三代蒽环类抗生素和强有力的DNA拓扑异构酶Ⅱ抑制剂,有望用于治疗SCLC。ACT-1研究对比了AMR和Topo二线治疗SCLC的安全性和功效。

  637例患者被随机(2:1)分配到AMR(第1~3日静脉给予40 mg/m2,n=424)或Topo治疗组(第1~5日静脉给予1.5 mg/m2,n=213),在研究最后1/3时间段,预防性给予患者白细胞生长因子。研究终点是生存期[主要终点是总生存期(OS)]、无进展生存期(PFS)和安全性。

  结果显示,AMR 对 Topo组基线特征相似:中位年龄62岁 对 61岁,<65岁的患者比例60% 对 65%,男性比例58% 对 60%,体能状态(PS)0分的比例30% 对 34%,难治性患者比例47% 对 45%。Cox模型中的协变量为PS为0分(是或否)、年龄、对一线铂类为基础治疗的反应(难治性、敏感性)和疾病分期(局限性、扩散性)。AMR和Topo组3/4级不良事件分别为中性粒细胞减少(41% 对 53%)、血小板减少(21% 对 54%)、贫血(16% 对 30%)、感染(16% 对 10%)、发热性中性粒细胞减少(10% 对 4%)(P值均<0.05)和心源性疾病(5% 对 5%,P=0.84)。AMR和Topo组输血率分别为32%和53%(P<0.01)。
