科学家们已经发现了一个重大发现,他们鉴定了一种突变,使癌细胞对阿斯利康的Lynparza和其他PARP抑制剂产生抗药性。

这些发现可以帮助预测哪些患者可能对PARP抑制剂的治疗产生耐药性,从而允许医生尽早调整治疗方案。

利用基因编辑技术,伦敦癌症研究所的一个研究小组能够确定PARP1蛋白中的一种特殊突变,使PARP抑制剂不起作用。

作者指出,对这种突变进行检测可能会加深个性化,从而有针对性地进行治疗,不仅有助于形成关于是否启动PARP抑制剂治疗的决定,而且还可以决定何时将患者转换为治疗方案。

ICR癌症基因组学教授Chris Lord教授说:"癌症耐药是我们在癌症治疗工作中面临的一个重大挑战。

"我们希望我们的研究能够帮助医生从一开始就使用最好的药物,迅速对早期的抵抗迹象作出反应,并制定出结合治疗以克服耐药性的最佳方法。"

"这一重要发现可能在未来让临床医生确定谁将从这些药物中获益最多,或者追踪何时药物疗效降低以及何时改变治疗方案可能是合适的,"乳腺癌现在首席执行官Delyth Morgan女士说。

"这样的研究是基于PARP抑制剂的开发,作为一些乳腺癌患者的全新治疗选择,可以帮助我们更接近更个性化的治疗方法。"

该研究由英国癌症研究和乳腺癌癌症研究中心资助,发表在《自然通讯》杂志上。

PARP抑制剂是最有前景的新型抗癌药物,其发展主要源于对DNA损害反应和DNA修复的治疗易感性的认识。最初PARP抑制剂临床疗效的研究始于10年前,因为体外研究发现该类药物对BRCA突变癌细胞具有明显的抗癌作用。该项临床研究对首个PARP抑制剂奥拉帕尼进行了检验,2014年根据该研究结果奥拉帕尼获得FDA和欧洲药监局批准上市。实际上早在2008年ASCO年会上,奥拉帕尼的I期结果就已明确显示,对既

ACCR年会:联合用药提高PARP抑制剂在耐药卵巢癌中的应答

来自Dana-Farber癌症研究所的科学家称,约三分之一的对PARP抑制剂无应答的卵巢癌患者接受激酶抑制剂治疗后,其肿瘤部分收缩。
