J Am Acad Dermatol:吉非替尼治疗难治性皮肤鳞状细胞癌的疗效如何?(单臂Ⅱ期临床试验)

2017-10-31 MedSci MedSci原创

背景:临床前数据表明了表皮生长因子受体(epithelial growth factor receptor,EGFR)对皮肤鳞状细胞癌(cutaneous squamous cell carcinomas,CSCC)的发病起着关键性作用。EGFR本身具有酪氨酸激酶活性,一旦与表皮生长因子(EGF)组合可启动细胞核内的有关基因,从而促进细胞分裂增殖。胃癌、乳腺癌、膀胱癌和头颈部鳞癌的EGFR表达增高

背景:临床前数据表明了表皮生长因子受体(epithelial growth factor receptor,EGFR)对皮肤鳞状细胞癌(cutaneous squamous cell carcinomas,CSCC)的发病起着关键性作用。EGFR本身具有酪氨酸激酶活性,一旦与表皮生长因子(EGF)组合可启动细胞核内的有关基因,从而促进细胞分裂增殖。胃癌乳腺癌、膀胱癌和头颈部鳞癌的EGFR表达增高。但关于EGFR抑制剂对难治性、复发性、和/或转移性CSCC的疗效的研究数据不足。

吉非替尼(Gefitinib)是一种口服表皮生长因子受体酪氨酸激酶(EGFR-TK)抑制剂(属小分子化合物)。对EGFR-TK的抑制可阻碍肿瘤的生长、转移和血管生成,并增加肿瘤细胞的凋亡。

目的:本研究旨在确定不能接受常规治疗(包括手术疗法、放射性疗法)的CSCC患者中吉非替尼的响应率。

方法:本研究是一个单臂II期临床研究。研究共纳入了40名接受吉非替尼治疗的患者,这些患者接受每天口服250毫克吉非替尼治疗,直至病情恶化或耐受性不良。预定的目标响应率为20%。

结果:整体响应率为16%(95%置信区间,0.06-0.32;37例患者中6名患者部分响应)。另有13名患者(35%)在治疗8周内的病情稳定。响应持续时间的中位数和无进展生存期分别为31.4个月(95%置信区间,3.91-不适用)和3.8个月(95%置信区间,2.2-5.7)。副作用与先前报道的吉非替尼治疗其他类型肿瘤时相似。

局限性:这是一个单一机构的单臂研究。不满足指定的目标响应率。

结论:吉非替尼在治疗难治性皮肤鳞状细胞癌时表现出了适度的活性,且不良事件的情况良好。

吉非替尼辅助治疗可以延缓EGFR突变型NSCLC术后复发

由吴一龙教授牵头并在2017年ASCO年会上口头报道的CTONG1104研究:吉非替尼对比长春瑞滨+顺铂辅助治疗II-IIIA期(N1-N2)EGFR敏感突变型非小细胞肺癌(ADJUVANT研究),是今年NSCLC领域的重磅研究。在ASCO会后,ASCO会务组挑选了本次年会中的重要研究,概述研究重要发现并汇聚专家观点,整理成文发布在THE ASCO POST。吴一龙教授的这一研究不仅被选为大会前瞻

国产吉非替尼将为非小细胞肺癌患者节约三成药费

肺癌是世界上最常见的恶性肿瘤之一,其中,非小细胞肺癌约占所有肺癌的80%,约75%的患者发现时已处于中晚期。而肺癌靶向药物吉非替尼改变了肺癌临床治疗技术,开启了肺癌精准治疗时代。

Lancet oncol:Dacomitinib用作携带EGFR突变的非小细胞肺癌的一线疗法的疗效和安全性。

Dacomitinib是二代不可逆EGFR酪氨酸激酶抑制剂。现研究人员现将Dacomitinib用作晚期EGFR突变阳性的非小细胞肺癌(NSCLC)的一线疗法时,与可逆转的EGFR酪氨酸酶抑制剂吉非替尼(Gefitinib)的疗效和安全性比对。

J CLIN ONCOL:吉非替尼在EGFR拷贝数增益的食管癌患者中疗效显著

食管癌吉非替尼(COG)试验是专门针对化疗耐药性食管癌二线治疗的唯一一个III期随机试验,包括食管腺癌和食管鳞癌。在COG试验中,450名患者被随机分配到吉非替尼组合安慰剂组。吉非替尼组患者的无进展生存期(PFS)和报告结果(PROs)均得到改善,反映出少数亚组患者对吉非替尼发生快速持久的反应。食管鳞癌和食管腺癌患者对吉非替尼的受益率相等。

JCO:哪种类型的食管癌用吉非替尼效果更佳?

食管癌-吉非替尼试验已证明:与对照组相比,表皮生长因子受体(EGFR)酪氨酸激酶抑制剂吉非替尼能改善化疗后病情进展的晚期食管癌患者的无进展生存期。少数患者表现出了快速而持久的缓解。近期发表在JCO上的一项研究假设,EGFR通路的遗传变异将会甄别出使用吉非替尼获益的患者,并对该假设做出了验证。食管癌-吉非替尼试验中,根据EGFR拷贝数增益(CNG)和EGFR、KRAS、BRAF和PIK3CA突变状况
