Plos One:Cherlerythrine与厄洛替尼联合治疗对非小细胞肺癌的作用如何?

2017-04-14 MedSci MedSci原创

有研究表明,肺癌的进展受到表皮生长因子受体(EGFR)信号传导与蛋白激酶C(PKC)途径之间相互作用的调控。EGFR和PKC的靶向结合可能在治疗肺癌中具有协同作用。近期,一项发表在杂志Plos One上的研究联合使用了厄洛替尼(erlotinib)和氯氰菊酯(Cherlerythrine Chloride),旨在研究上述两种途径在非小细胞肺癌(NSCLC)中的潜在用途。在厄洛替尼不敏感的细胞系SK

有研究表明,肺癌的进展受到表皮生长因子受体(EGFR)信号传导与蛋白激酶C(PKC)途径之间相互作用的调控。EGFR和PKC的靶向结合可能在治疗肺癌中具有协同作用。


近期,一项发表在杂志Plos One上的研究联合使用了厄洛替尼(erlotinib)和氯氰菊酯(Cherlerythrine Chloride),旨在研究上述两种途径在非小细胞肺癌NSCLC)中的潜在用途。

在厄洛替尼不敏感的细胞系SK-MES-1和A549中,分别予以厄洛替尼或Cherlerythrine或者两者的联合治疗。体外实验评估细胞活力、克隆生存期、细胞迁移、侵袭、细胞凋亡效应和免疫印迹。在体内实验中评估肿瘤的生长。

此项研究显示:在所有NSCLC细胞系中,与erlotinib治疗相结合的chelerythrine具有叠加作用,导致肿瘤细胞活力、克隆生成、迁移和侵袭能力以及诱导凋亡的显着降低。此外,联合治疗导致肿瘤生长的显着延迟。

此种治疗通过降低下游靶点如STAT3,ERK1 / 2,p38 MAPK和Bad蛋白的磷酸化来有效阻断EGFR的信号传导。

此项研究支持肺癌中EGFR和PKC通路之间功能的相互作用,为厄洛替尼敏感性非小细胞肺癌患者提供临床可以利用的策略。

NICE再次更新厄洛替尼与吉非替尼指南

经过前期协商之后,NICE进一步更新的草案指南于8月7日发布。新的草案指南临时推荐厄洛替尼作为一种治疗选择用于特定情况下经过先前化疗后病情又出现恶化的非小细胞肺癌患者,但另一款癌症药物吉非替尼未得到推荐。厄洛替尼与吉非替尼均是EGFR-TKi抑制剂,它们通过阻断信号通路,通过延缓肿瘤增长与扩散而起作用。 在现在的NICE指南中,厄洛替尼通过一项患者获取计划来获得,替代多西他赛作为先前化疗

收官之战:Figitumumab不能提高厄洛替尼对非腺癌型NSCLC的疗效

研究背景:胰岛素样生长因子受体(1GF-IR)所介导的信号通路在促进有丝分裂活性、正常细胞恶性转化以及肿瘤细胞增殖、侵袭方面具有重要作用,因而成为抗肿瘤治疗的新靶点。目前靶向IGF-IR的药物主要有单克隆抗体和酪氨酸激酶抑制剂,其中Figitumumab(CP-751871) 是完全人源化的IGF-1R单克隆抗体。肺癌临床前研究中发现,Figitumumab具有良好的抗肿瘤活性及促进细胞毒化疗作用

JCO:厄洛替尼治疗EGFR突变肺癌患者有效

目的:AUY922是一种会引起HSP分子伴侣及其伴随蛋白,包括表皮生长因子受体,降解的Hsp90抑制剂。为评估AUY922和厄洛替尼治疗EGFR突变肺癌患者的效果,及研究在进行厄洛替尼治疗时疾病的进展,我们进行了一个I / II两阶段的临床试验。 方法:所有患者均在厄洛替尼治疗后获得抗性,并在EGFR T790M突变研究项目评估之前进行了重复的肿瘤活检。在第一阶段,18例患者进行了每周一次的AU

厄洛替尼对EGFR突变的IA-IIIA期NSCLC术后维持治疗可能获益(SELECT研究)

表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI)治疗EGFR敏感突变的晚期非小细胞肺癌(NSCLC)疗效卓越,多个随机对照研究确定了一线使用EGFR-TKI可改善EGFR突变肺癌的肿瘤缓解率和无进展生存期(PFS),本届ASCO上,报告了LUX3和LUX6研究的汇总结果,一线TKI可改善EGFR突变肺癌,尤其是19缺失肺癌的总体生存(OS)。EGFR突变肺癌TKI的适应症已从二线到一线,能否从

JCO:吉非替尼vs.厄洛替尼的非劣效性研究

 在全球范围,肺癌是一种主要致死的癌症。肺癌中有大约85%是非小细胞肺癌,最常见的非小细胞肺癌的类型是腺癌。随之靶向表皮生长因子受体EGFR酪氨酸激酶的药物的问世,非小细胞肺癌尤其是腺癌的治疗已经取得了巨大的进展。吉非替尼和厄洛替尼作为第一代EGFR酪氨酸激酶抑制剂,二者具有相同的骨架结构,不可逆地结合在EGFR的ATP结合口袋。厄洛替尼推荐的和最大的耐受剂量是相同的,均为150mg/d

Ann Oncol:厄洛替尼对比化疗一线治疗对EGFR突变NSCLC患者总生存期影响 (OPTIMAL, CTONG-0802研究)

CTONG-0802,也称OPTIMAL研究首次比较EGFR酪氨酸激酶抑制剂(TKI)厄洛替尼和标准化疗一线治疗EGFR突变晚期非小细胞肺癌(NSCLC)患者的临床效果和耐受性。化疗方案采用吉西他滨+卡铂方案。在前期的PFS研究结果中发现,厄洛替尼显著优于化疗方案,两者PFS分别为13.1个月 [95% CI 10.58-16.53] 和4.6个月 [4.21-5.42](HR:0.16,&nbs
