Wiley顶级期刊Small (IF=10.856)近日发表了一篇由同济大学附属上海市肺科医院张哲民教授、同济大学高等研究院杨洋教授和格诺生物科技(中国)有限公司(以下简称格诺生物)联合开展的真实世界研究的研究论文。该项研究纳入3798例低剂量CT(以下简称LDCT)影像学检查发现肺部小结节的患者,通过对比叶酸受体循环肿瘤细胞(以下简称FR+CTC)与各项临床指标之间的相关性,认为FR+CTC检测作为非侵入式检测技术,对诊断全期肺癌的灵敏度为87.05%,可提高肺结节诊断灵敏度,从而改善肺结节筛查和诊断流程。

研究背景

近年来,随着LDCT在临床的普及,肺结节的检出率显着增加。确定结节的良恶性是后续临床决策和治疗方案的关键,但由于缺乏敏感的诊断指标,往往并不能给出准确的诊断方案。因此,迫切需要提高我们对LDCT筛查出的肺结节准确诊断的能力。限制我们诊断的主要因素是缺乏获取患者和样本的途径。由于肺组织收集具有有创性,液体活检是一种可行的替代方案。外周血中含有少量的肿瘤细胞,即循环肿瘤细胞(CTC)。早在150多年前,CTC已经被发现,然而由于外周血中CTC稀有,富集和识别CTC存在技术壁垒。近年来,随着免疫磁珠技术的发展,使得研究人员可以重新评估CTC是否可以应用在肺癌筛查和诊断流程中。本研究中,我们基于免疫磁珠从外周血分离和浓缩叶酸受体(FR)阳性CTCs,开发并验证了一种简单易用的CTC富集检测方案,以改善肺部病变的诊断。

研究方法

该研究在上海市肺科医院的胸外科招募了3798名即将进行手术的肺部病变患者,在手术前采集3ml外周血,使用FR+CTC检测技术富集检测CTC,对比FR+CTC与各项临床指标(基因表达、TNM分期、胸膜浸润等)之间的相关性。

FR+CTC检测原理

研究结果

研究首先对比了CTC与各项临床指标之间的相关性,发现CTC与PIK3CA、ALK及BRAF三个肺癌关键驱动基因相关,也与TNM分期及胸膜浸润相关。

f

在本研究中,FR+CTC以8.7 FU/3mL为阈值时检测全期肺癌的灵敏度为87.05%(2468/2835)。研究同时比对了高于阈值和低于阈值两组患者各类临床病理特征,再次证实通过联合CTC检测,可提高肺结节诊断灵敏度。

研究结论

本研究在大量的患者中发现,基于白细胞负向富集和FR特异性的方法来评估CTCs的FR+CTC检测技术,可提高肺结节诊断的敏感性,从而改善肺结节筛查和诊断流程。

FR+CTC研究现状

FR+CTC上市至今,其多项临床研究成果已分别发表于JTO、JAMA Surgery、柳叶刀子刊Ebiomedicine等高影响力SCI期刊,研究数据也被2019年中国肺癌防治联盟、中华医学会呼吸病学分会肺癌学组和中国医师协会呼吸医师分会肺癌工作委员会联合推出的《肺癌筛查与管理中国专家共识》引用。
