J Clin Oncol:PD-L1免疫组化检测:NSCLC中的分析及临床应用

2017-12-26 张琪 环球医学

根据NCCN指南,在晚期非小细胞肺癌患者一线治疗前需要检测驱动基因的突变状态,根据其突变状态选择相应的靶向药物,可以从靶向药物中获益。而对于没有驱动基因突变的患者,应该进行程序性死亡配体1(PD-L1)免疫组化检测。2017年12月,发表在《J Clin Oncol》的一项研究调查了PD-L1免疫组化检测在非小细胞肺癌(NSCLC)中的分析及临床应用。

根据NCCN指南,在晚期非小细胞肺癌患者一线治疗前需要检测驱动基因的突变状态,根据其突变状态选择相应的靶向药物,可以从靶向药物中获益。而对于没有驱动基因突变的患者,应该进行程序性死亡配体1(PD-L1)免疫组化检测。2017年12月,发表在《J Clin Oncol》的一项研究调查了PD-L1免疫组化检测在非小细胞肺癌NSCLC)中的分析及临床应用。

目的:目前3种程序性死亡配体-1/PD-L1抑制剂被批准用于NSCLC的治疗。派姆单抗治疗NSCLC需要进行PD-L1免疫组化(IHC)检测。尼鲁单抗和阿特朱单抗被批准不需要进行PD-L1检测,尽管美国食药监局已经通过补充性PD-L1检测,对这两种药物均可用。用于评价临床试验中PD-L1在接受程序性死亡配体-1/PD-L1抑制剂的患者中的表达的PD-L1 IHC方法包括PD-L1 IHC 28-8 pharmDx(28-8)、PD-L1 IHC 22C3 pharmDx(22C3)、Ventana PD-L1 SP142(SP142)和Ventana PD-L1 SP263(SP263)。抗体及IHC平台不同可能导致检测及诊断应用方面具有不可比的问题。本次综述为帮助医师和病理学家理解分析特征和各类PD-L1 IHC的可比性及其在诊断方面的使用提供实践信息。

方法:研究者评价并总结了临床试验和实验室研发的PD-L1免疫组化检测方法(LDAs)相关已发表或报告的研究(2016年1月至2017年1月)。分析了评价诊断方法对PD-L1表达水平影响的研究,以阐明用于检测的组织标本相关的实际问题。

结果:对肿瘤细胞膜上的PD-L1表达的28-8、22C3和SP263临床试验检测一致性高、观察者间可重复性强,而用SP142检测出的PD-L1表达较低。免疫细胞PD-L1表达可变且不同观察者间一致性差。肿瘤内和肿瘤间的异质性对PD-L1表达具有不同的影响。LDAs的一致性具有较大的不同。

结论:在评估肿瘤细胞膜上的PD-L1表达时,28-8、22C3和SP263之间的一致性高,表明NSCLC临床应用的可互换性,但用于评估免疫细胞上PD-L1的表达,这三种方法不能互换。在推荐常规临床应用前,LDAs需要进行严格的标准化。

Lancet:Atezolizumab不能延长PD-L1过表达的铂难治性转移性尿路上皮癌患者生存期

研究认为,对于PD-L1过表达的铂难治性转移性尿路上皮癌患者,Atezolizumab治疗相比于化疗不能显著延长患者总生存期,但治疗副作用更低

JCO:Pembrolizumab治疗晚期PD-L1阳性宫颈癌的安全性和有效性

KEYNOTE-028临床试验评估了Pembrolizumab对PD-L1阳性晚期实体肿瘤患者的安全性和有效性。JCO近期发表了一篇文章,研究其在晚期宫颈癌患者中的临床试验结果。

Clin Cancer Res:头颈部肿瘤患者血浆中PD-L1 +外泌体的临床意义

头颈部鳞状细胞癌(HNSCCs)的微环境具有高度免疫抑制性。表达高水平PD-L1的HNSCC具有特别差的预后。从HNSCC患者的血浆中分离出携带PD-L1并抑制T细胞功能的外泌体。评估了PD-L1 +外泌体对免疫抑制和疾病活性的潜在贡献。

Oncotarget:PD-1 / PD-L1免疫检查点的小分子抑制剂能够减轻PD-L1诱导的T细胞耗竭

尽管针对PD-1 / PD-L1免疫检查点的抗体近年来在抗癌治疗方面取得了令人瞩目的成就。 相比之下,目前仍没有针对PD-1 / PD-L1免疫检查点的小分子化合物的报道,相比于经静脉注射给药或皮下注射给药方式,小分子独有的口服给药方式会极大提高患者的依从性。近日波兰学者在Oncotarget杂志中报道了几种小分子能够减轻PD-1 / PD-L1免疫检查点介导的Jurkat T淋巴细胞衰竭,这两种

CLIN CANCER RES:肝细胞癌免疫微环境特点

肝细胞癌是一种恶性肿瘤,通常由慢性肝脏疾病或肝硬化发展而来。世界范围内肝细胞癌是肿瘤相关死亡的第二大因素。肝细胞癌的主要风险因素包括肝炎肝硬化,酒精性肝疾病和非酒精性脂肪肝。肝细胞癌可能对免疫治疗存在反应。CLIN CANCER RES近期发表了一篇文章,研究肝细胞癌的免疫微环境特点。

CLIN CANCER RES:前列腺癌Neo-AAPL治疗与PD-L1表达

PD-L1/PD-1阻滞在前列腺癌治疗中是不成功的,可能的原因是前列腺癌免疫原性差以及PD-L1低表达。近期有研究认为有一些前列腺癌可以显着表达PD-L1。而且在临床前模型中激素受体拮抗剂enzalutamide可以上调前列腺癌PD-L1表达。CLIN CANCER RES近期发表了一篇文章,研究新辅助阿比特龙去势治疗联合泼尼松及亮丙瑞林(Neo-AAPL)对前列腺癌PD-L1表达的影响。
