Nature:肿瘤突变靶向药物的疗效受突变类型及肿瘤组织环境影响!

2018-02-08 佚名 “细胞”微信号

一大群来自美国、西班牙和澳大利亚的科学家发现旨在靶向特殊基因突变的抗癌药物的疗效依赖于涉及的肿瘤组织的类型以及基因突变的性质。在他们这项发表于《Nature》的新研究中,研究人员描述了他们的临床试验和结果。来自美国国家儿童医院遗传医学研究所的Elaine Mardis对这项研究进行了评论,并就癌症相关基因异常的研究和可能的治疗选择给出了他的看法。

一大群来自美国、西班牙和澳大利亚的科学家发现旨在靶向特殊基因突变的抗癌药物的疗效依赖于涉及的肿瘤组织的类型以及基因突变的性质。在他们这项发表于《Nature》的新研究中,研究人员描述了他们的临床试验和结果。来自美国国家儿童医院遗传医学研究所的Elaine Mardis对这项研究进行了评论,并就癌症相关基因异常的研究和可能的治疗选择给出了他的看法。

过去医生都以相同的方式治疗同一种肿瘤病人,但是最近的研究发现这可能不是最佳的策略。这是因为不是所有同一类的肿瘤都相似。比如不是所有的肺癌病人的肿瘤都一样——每个病人的诱因和发展都不一样。考虑到这个因素,科学家们已经在寻找方法基于病人自身情况给出个性化治疗方案。由于这种方法已经取得了一定的进展,科学家们也发现肿瘤的大部分不同都可以归结于基因不同。在这项新研究中,研究人员聚焦于ERBB2和ERBB3基因,因为已有研究发现它们可以过表达HER2蛋白。

为了研究ERBB2和ERBB3基因在肿瘤发展中发挥的作用,研究人员在临床实验中使用来那替尼治疗了141个病人(共患有21种癌症,42种突变),它可以抑制HER的产生。他们发现这个药物的效果依赖于突变和组织环境。一些病人携带ERBB2突变,他们对这个药物响应很好,尤其是那些HER2胞外段或者是激酶结构域出现突变的病人。而其他表达HER2的病人对该药物响应不太好,而携带ERBB3的病人对这个药物根本就不产生反应。

研究人员认为他们的研究表明针对特定突变的疗法必须考虑肿瘤组织以及肿瘤组织涉及的组织性质。
