Eur J Cancer:Cabozantinib治疗卵巢癌的有效(随机停药试验)

2017-07-31 MedSci MedSci原创

背景:Cabozantinib(XL184)是血管内皮生长因子受体2和MET的口服抑制剂,近期来自美国的研究人员一个卵巢癌患者的2期队列研究中探讨了它的疗效和安全性,该试验是一个由九个不同类型的肿瘤组成的随机停药试验(RDT)的一部分。病人和方法:患者接受100毫克Cabozantinib,每日。那些在12周时,通过肿瘤反应评估标准判断为病情稳定(SD)的实体瘤患者接受随机分配Cabozantin

背景:Cabozantinib(XL184)是血管内皮生长因子受体2和MET的口服抑制剂,近期来自美国的研究人员一个卵巢癌患者的2期队列研究中探讨了它的疗效和安全性,该试验是一个由九个不同类型的肿瘤组成的随机停药试验(RDT)的一部分。

病人和方法:患者接受100毫克Cabozantinib,每日。那些在12周时,通过肿瘤反应评估标准判断为病情稳定(SD)的实体瘤患者接受随机分配Cabozantinib或安慰剂。主要终点为随机分配后第12周的无进展生存期(PFS)的客观缓解率(ORR)。

结果:七十例卵巢癌患者被纳入该RDT研究,其中50%为铂类难治性/耐药性患者。从第一天开始的平均PFS为5.5个月。第12周的ORR为21%;1例患者达到了完全缓解(CR),14例(20%)患者达到部分缓解(PR)。第12周时,总的疾病控制率(CR + PR + SD) 为50%。在整个研究过程中,基线后扫描≥1的患者中70%的患者的肿瘤消退,并提前终止试验。病情稳定患者中被随机到Cabozantinib组者,PFS为5.9个月。最常见的3级或4的不良反应为腹泻(14%)、掌足红肿综合征(6%)、乏力(6%)、高血压(6%)和中性粒细胞减少症(6%)。在最初的12周内,37%的患者需要减少剂量。

结论:基于ORR和肿瘤靶病变的消退,Cabozantinib在卵巢癌患者中具有临床活性,且其毒性在可接受范围内。

Oncotarget:Aurora A激酶通过调节DNA修复与卵巢癌治疗相关

卵巢癌发病隐匿,发现时往往已是疾病的晚期。手术治疗难以达到满意的疗效,化疗一般疗程长,副反应重,患者很难承受,且容易出现耐药。Aurora A激酶(AURKA)是极光激酶家族成员之一,为蛋白质丝氨酸/苏氨酸激酶,其通过调节有丝分裂和染色体不稳定性在卵巢癌的发展过程中起重要作用。PARP是细胞凋亡核心成员半胱天冬酶(caspase)的切割底物,它在DNA损伤修复与细胞凋亡中发挥着重要作用。

鞘氨醇激酶1(SK1)是促凋亡和促生存神经脂质中关键的细胞平衡调节器。受SK1调控的致癌信号通路需要依赖SK1定位到质膜上,其定位通过Ca2+十四酰开关功能被钙离子和整合素结合蛋白CIB1介导。本文中,我们研究了CIB家族中的另一个成员CIB2,CIB2在SK1信号通路的调控中发挥着与CIB1截然相反的作用。CIB2能够和SK1结合,结合位点与CIB1相同,但是CIB2缺乏Ca2+十四酰开关功能。
