Lancet Oncol:阿法替尼治疗晚期非小细胞肺癌的罕见EGFR突变的临床活性

2015-06-05 MedSci MedSci原创

背景:大多数非小细胞肺癌患者具有EGFR突变,即在外显子19有缺失突变或外显子21中的Leu858Arg点突变,或二者兼有(即,共同的突变)。但是,部分患者(10%)的EGFR突变肿瘤隐藏有罕见的突变。关于这些肿瘤对EGFR抑制剂的敏感性的数据很少。下面是研究人员研究得出的晚期非小细胞肺癌中隐藏有罕见突变的癌症患者使用阿法替尼的疗效的数据。 br> 方法:在这个事后分析中,研究人采用

背景:大多数非小细胞肺癌患者具有EGFR突变,即在外显子19有缺失突变或外显子21中的Leu858Arg点突变,或二者兼有(即,共同的突变)。但是,部分患者(10%)的EGFR突变肿瘤隐藏有罕见的突变。关于这些肿瘤对EGFR抑制剂的敏感性的数据很少。下面是研究人员研究得出的晚期非小细胞肺癌中隐藏有罕见突变的癌症患者使用阿法替尼的疗效的数据。
br>
方法:在这个事后分析中,研究人采用前瞻性酪氨酸激酶抑制剂初治EGFR突变阳性的晚期(阶段IIIB-IV)肺腺癌患者收集数据,这些患者在单组Ⅱ期临床试验(LUX-Lung2)和随机Ⅲ期试验(LUX-Lung3和LUX-Lung6)被给予阿法替尼治疗。分析是在意向治疗人群中进行,包括所有随机分配的罕见EGFR突变患者。EGFR突变的类型(外显子19缺失[del19],外显子21 Leu858Arg点突变,或其他)和人种类型(只是LUX-Lung3;亚洲与非亚洲)是随机试验预先指定的分层因素。
    
结果:600名患者中,被分为三个试验组给予阿法替尼,并且所有患者中有75(12%)例患者有少见EGFR突变(38例在第1组,14例在第2组,23例在第3组)。第1组中的27例患者有客观反应(71.1%,95%Cl 54.1-84.6),第2组中有2例(14.3%,1.8-42.8),第3组中有2例(8.7%,1.1-28.0)。第1组的中位无进展生存期为10.7个月(95%Cl 5.6-14.7),第2组为2.9个月(1.2-8.3),第3组为2.7个月(1.8-4.2)。第1组总的中位生存期为19.4个月(95%Cl 16.4-26.9),第2组为14.9个月(8.1-24.9),第3组为9.2个月(4.1-14.2)。对于最常发生的罕见基因突变,14例Gly719Xaa患者(77.8%,95%Cl 52.4-93.6)有一个客观反应,同样,Leu861Gln组有9例(56.3%,29.9-80.2),Ser768Ile有8例(100.0%,63.1-100.0)有这样的情况。
    
结论:阿法替尼对于非小细胞肺癌的隐藏的某些类型的罕见EGFR突变的肿瘤,尤其Gly719Xaa,Leu861Gln和Ser768Ile是有活性的,但在其它突变类型中活性较低。但对于de-novo Thr790Met Thr790Met和20号外显子插入突变的患者的临床效果不佳。这些数据可以帮助非小细胞肺癌隐藏的罕见的EGFR突变患者提供临床决策。

Lancet Oncol:阿法替尼作为复发或转移性鳞状细胞癌患者的二线治疗

背景:复发或转移性鳞状细胞头颈部癌(HNSCC)一线铂方案治疗后有不良预后,且有很少的治疗方案选择。阿法替尼,不可逆转ERBB家族抑制剂,在II期临床研究中显示有疗效。我们旨在评估阿法替尼与甲氨蝶呤用于复发或转移性头颈部鳞状细胞癌铂治疗后作为二线治疗的有效性和安全性。方法:在19个国家101个中心进行的开放标签的、III期的随机对照试验,我们招募18岁或以上,组织学或细胞学上证实为鳞状细胞头颈部癌

Lancet Oncol:阿法替尼治疗鳞状细胞癌

患有复发性或者转移性的头颈部鳞状细胞癌的病人经过铂类药物治疗的预后并不理想,而且目前也没有明确的标准疗法。在一项回顾性分析中,头颈部鳞状细胞癌的平均存活时间大概为1.8个月。甲氨蝶呤、紫杉烷和西妥昔单抗被单独使用或者联用作为铂类药物治疗失败后的二线疗法,尽管这种疗法缺乏随机试验的证明。阿法替尼是一种不可逆的ERBB受体家族阻断剂,在头颈部鳞状细胞癌的2期临床试验中展现出了良好疗效。 为此,研

Oncologist:阿法替尼治疗EGFR-TKIs获益的非小细胞肺癌患者进展后的经验分析

背景:作为ErbB家族非可逆性抑制剂,阿法替尼相比一线化疗方案,在EGFR突变的非小细胞肺癌患者中呈现一定的优越性。同时,阿法替尼在EGFR-TKIs(EGFR酪氨酸激酶抑制剂)治疗进展后仍然表现出疗效。本试验报道了体恤用药组织中的非小细胞肺癌患者应用阿法替尼后的研究结果。研究方法:本试验研究对象入选标准:非小细胞肺癌患者一线及以上化疗进展后、接受EGFR-TKIs的EGFR突变或曾经临床获益后进
