NEJM:卡博替尼治疗晚期和进展性肝细胞癌

2018-07-05 xing.T MedSci原创

由此可见,在既往治疗过的晚期肝细胞癌患者中,与安慰剂相比,使用卡博替尼治疗可获得更长的总生存期和无进展生存期。卡博替尼组中高级别不良事件的发生率约为安慰剂组的两倍。

卡博替尼抑制酪氨酸激酶,包括血管内皮生长因子受体1、血管内皮生长因子受体2、血管内皮生长因子受体3、MET和AXL,这些分子参与了肝细胞癌的进展和索拉非尼耐药性的产生,索拉非尼是晚期肿瘤的标准治疗。近日,顶级医学期刊NEJM上发表了一篇研究文章,这项随机、双盲、3期试验评估了卡博替尼与安慰剂相比对既往治疗过的晚期肝细胞癌患者的疗效。

该研究共有707名患者以2:1的比例随机分配接受卡博替尼(60 mg,每日一次)或匹配的安慰剂治疗。符合条件的患者先前曾接受过索拉非尼治疗,在至少一次肝细胞癌全身治疗后病情进展,并且可能已经接受了多达两种晚期肝细胞癌全身治疗方案。该研究主要终点是总体生存期。次要终点是无进展生存期和客观反应率。

在第二次计划的中期分析中,试验显示卡博替尼的总生存期明显长于安慰剂。卡博替尼的中位总生存期为10.2个月,安慰剂组为8.0个月(死亡风险比为0.76; 95%置信区间[CI]为0.63-0.92; P=0.005)。卡博替尼中位无进展生存期为5.2个月,安慰剂组为1.9个月(疾病进展或死亡风险比为0.44; 95%CI为0.36-0.52; P<0.001),客观反应率分别为4%和小于1%(P=0.009)。卡博替尼组68%的患者发生3级或4级不良事件,安慰剂组36%的患者发生不良事件。最常见的高级别不良反应事件是手掌-足底红斑感觉(卡博替尼为17%,安慰剂为0%)、高血压(16% vs. 2%)、天冬氨酸氨基转移酶水平升高(12% vs. 7%)、疲劳( 10% vs. 4%)和腹泻(10% vs. 2%)。

由此可见,在既往治疗过的晚期肝细胞癌患者中,与安慰剂相比,使用卡博替尼治疗可获得更长的总生存期和无进展生存期。卡博替尼组中高级别不良事件的发生率约为安慰剂组的两倍。
