Cell:我们找到了早期肺癌免疫治疗新靶点

2017-05-23 佚名 药明康德

诸如PD-1和PD-L1免疫检查点抑制剂等肿瘤免疫疗法在治疗晚期或转移肺癌中已经取得了巨大的成功。但是目前治疗早期肺癌的标准疗法仍然是手术和化疗,那么肿瘤免疫疗法能否用于治疗早期肺癌呢?

诸如PD-1和PD-L1免疫检查点抑制剂等肿瘤免疫疗法在治疗晚期或转移肺癌中已经取得了巨大的成功。但是目前治疗早期肺癌的标准疗法仍然是手术和化疗,那么肿瘤免疫疗法能否用于治疗早期肺癌呢?

日前,美国西奈山医学院(Mount Sinai School of Medicine) 的研究人员对早期肺癌肿瘤的免疫微环境进行了详细研究。他们发现让肿瘤免疫疗法得以成功的免疫因素在早期肺癌的微环境中已经存在,这意味着免疫疗法很有希望在早期肺癌患者身上同样取得成功。这项研究发表在《细胞》杂志上。

目前,治疗早期肺癌患者的常用疗法仍然是手术治疗和辅助化疗。处于IA和IB期的早期非小细胞肺癌患者接受治疗后5年存活率分别为83%和71%,而处于II期的患者存活率就只有50%。这说明对早期肺癌的治疗仍然有很大的提升空间。虽然PD-1或PD-L1抗体这类免疫检查点抑制剂在治疗晚期肺癌方面已经显示出优异的疗效,但是它们并没有被用来治疗早期肺癌患者。其中的一个重要原因是我们对早期肺癌肿瘤附近微环境的免疫状况并不了解。免疫检查点抑制剂能否成功,取决于肿瘤周围是否已经存在着可以杀伤肿瘤的免疫细胞,以及这些免疫细胞的抗癌能力是否受到了PD-1或PD-L1等免疫检查点蛋白的抑制。因此,了解早期肺癌肿瘤微环境的免疫状况非常重要。

西奈山医学院的研究人员从早期肺癌患者身上获取了切除的肿瘤组织、正常肺部组织和血样。他们设计出一种条形码系统可以对这三种不同样本中的所有细胞用金属同位素贴上标签。然后运用飞行时间质谱技术 (mass cytometery by time-of-flight)与单个细胞转录组学(single cell transcriptomics)和对肺部肿瘤的多重成像技术相结合,对肺部肿瘤的免疫状况在单个细胞的水平上进行详细分析。

对肺癌肿瘤在单个细胞水平上的多维刨析(high-dimensional single-cell profiling) 表明在肺癌初期,肿瘤周围就聚集着所有主要免疫细胞类型,其中最多的是T淋巴细胞和单核吞噬细胞。调节性T细胞也已经在早期肿瘤周围富集。免疫检查点蛋白PD-1和PD-L1也已经分别出现在一部分CD4+和CD8+的T淋巴细胞和巨噬细胞表面。这些在晚期肺癌中发现的免疫特征在早期肺癌中也同样存在。这意味着PD-1或PD-L1抑制剂很有可能在早期肺癌中也能获得同样的疗效。

这一研究同时发现许多其他的免疫疗法的新靶点,从而能够显着增加从免疫疗法中获益的患者人数。研究结果目前正在被用来帮助开发早期肺癌患者的免疫疗法临床试验。

“大约50%的肺癌患者在接受治疗后癌症会复发,”这项研究的资深作者,西奈山医学院的肿瘤科学和医学教授Miriam Merad博士说:“当肺癌进入晚期时,化疗没有很好的疗效,因此知道如何在肺癌早期杀伤肿瘤细胞对患者复发和最终的存活率有着重大的影响。我们的研究证明了免疫疗法在癌症早期,尤其在那些从未接触过化疗的患者身上是最有效的。”

【原型药物运用新机制治疗肺癌】细胞通过分子开关(磷酸分子)不断转化蛋白质,这些成分已经成为常见的药物靶点。在一项新研究中,通过直接激活肿瘤抑制蛋白的新型小分子在小鼠中预防了肺癌肿瘤。凯斯西储大学的Goutham Narla博士说:“我们目前治疗癌症患者的所有药物都是针对我们所谓的激酶,它将磷酸分子粘附到蛋白质上,但同样重要的是将磷酸盐关闭。” 一种酶-PP2A可以通过除去附着于其上的磷酸

Nat Commun:肺癌细胞如何将你的肺淹没?

当流体聚集在肺和胸壁之间的空间时,肺癌患者特别容易发生恶性胸腔积液。 Helmholtz ZentrumMünchen与德国肺研究中心(DZL)合作的研究人员发现了一种引发这种情况的新机制。他们的研究发表在“自然通讯”中,也显示出各种活性物质可能被用于治疗这种病症。

半数肺癌发现时已是晚期,靶向药物能否控制肿瘤

肺癌作为危害我国公众健康的重大疾病,给社会、家庭和个人带来了沉重的疾病负担。据统计,我国每年新发病的肺癌患者超过73万人,肺癌死亡人数超过61万,而总体五年生存率仅为16.1%。生存率低的一大原因在于,早期肺癌检出率低,不少患者在发现时已经是晚期。为什么肺癌发现的时候大部分都是晚期?这是很多患者及家属十分疑惑的一点。广东省人民医院吴一龙教授解释,现有的数据显示,肺癌患者50%发现时已经是晚期。这主

Plos One:非小细胞肺癌患者的EGFR突变比例与TKI治疗密切相关!

分析表皮生长因子受体(EGFR)可以评估非小细胞肺癌(NSCLC)患者对酪氨酸激酶抑制剂(TKIs)治疗的反应性。目前,以及在肺癌中观察到肿瘤内分子异质性的存在。近期,一项发表在杂志Plos One的研究旨在评估肿瘤样品中突变的肿瘤细胞的百分比是否会影响对TKIs治疗的反应。此项研究使用下一代测序仪,共分析了931例NSCLC患者的EGFR突变状态(外显子18,19,20,21)。在将下一代测序仪
