JCO:舒尼替尼维持治疗可改善小细胞肺癌无进展生存期PFS(II期研究)

2015-05-04 徐媛媛译 MedSci原创

目的:评估的化疗后使用舒尼替尼治疗小细胞肺癌(SCLC)的有效性。 该试验是一项随机、安慰剂对照、二期试验。将收纳的患者按1:1被随机分配到对照组或舒尼替尼治疗组并进行每天37.5mg直到有进展。交叉后进展是允许的。 本研究一共收纳了144名患者,其中,138名患者接受化疗,95名患者被随机分分配到对照组,10名患者没有接受维持治疗。85名患者接收了维持治疗(对照组组41名;舒尼替尼组

目的:评估的化疗后使用舒尼替尼治疗小细胞肺癌(SCLC)的有效性。

该试验是一项随机、安慰剂对照、二期试验。将收纳的患者按1:1被随机分配到对照组或舒尼替尼治疗组并进行每天37.5mg直到有进展。交叉后进展是允许的。

本研究一共收纳了144名患者,其中,138名患者接受化疗,95名患者被随机分分配到对照组,10名患者没有接受维持治疗。85名患者接收了维持治疗(对照组组41名;舒尼替尼组44名)。在舒尼替尼组中,3级不良事件包括疲劳(19%),中性粒细胞减少(7%),白细胞减少(7%),和血小板减少(7%)。在安慰剂组中,只有疲劳(10%)发生在超过5%的队列中。在舒尼替尼组中,4级不良事件包括1例患者出现级消化道出血,1例出现胰腺炎,低血钙,和脂肪酶升高。在安慰剂组中,血小板减少症有1例患者,高钠血症出现1例。对照组中位PFS是3.7个月,舒尼替尼组中位PFS为2.1个月(HR, 1.62; 70% CI, 1.27 to 2.08; 95% CI, 1.02 to 2.60; one-sided P = .02)。中位总生存期,安慰剂组是6.9个月,舒尼替尼组是9个月(HR, 1.28; 95% CI, 0.79 to 2.10; one-sided P = .16)。在舒尼替尼组维持治疗过程中,有三例患者得到缓解。在对照组的13名患者中有10名(77%)患者在进展后转至舒尼替尼治疗被评估为病情稳定(6~27周)。

结论:舒尼替尼维持治疗具有安全以及改善小细胞肺癌无进展生存期(PFS)。
