Chest:EBUS-TBNA与切除肺癌标本之间PD-L1免疫组化染色的比较

2018-08-01 xiangting MedSci原创

EBUS-TBNA的PD-L1阈值≥1%与切除肿瘤标本有强相关性。当PD-L1≥50%时,与切除肿瘤相比,EBUS-TBNA标本的敏感性和PPV显著降低。

晚期非小细胞肺癌NSCLC)中,来自支气管内超声引导的经支气管针吸活检(EBUS-TBNA)的小活检标本通常是唯一来自癌症组织可用于分析程序性死亡配体-1(PD-L1)表达的材料。这项研究目的是评估与其对应的手术切除肿瘤相比,EBUS-TBNA样本中PD-L1表达≥1%和≥50%的敏感性、特异性、阳性预测值(PPV)和阴性预测值(NPV)。

研究人员回顾性分析了2006年7月至2016年9月期间接受EBUS-TBNA并随后手术切除NSCLC的所有患者。收集了人口统计学信息和围手术期/手术数据。重新分析存档标本并评估PD-L1。使用两个单独的临界点来定义PD-L1染色阳性:≥1%和≥50%的肿瘤细胞阳性。将EBUS-TBNA吸出物与手术切除标本进行比较,以计算敏感性、特异性、PPV和NPV。

该研究纳入了61名患者。当PD-L1≥1%时,敏感性、特异性、PPV和NPV分别为72%、100%、100%和80%。当PD-L1≥50%时,敏感性、特异性、PPV和NPV分别为47%、93%、70%和84%。PD-L1≥1%和≥50%的一致率分别为87%和82%。

EBUS-TBNA的PD-L1阈值≥1%与切除肿瘤标本有强相关性。当PD-L1≥50%时,与切除肿瘤相比,EBUS-TBNA标本的敏感性和PPV显著降低。当使用≥50%作为阈值分析PD-L1表达时,EBUS-TBNA样本会将PD-L1状态进行错误分类。

CLIN CANCER RES:M7824治疗晚期实体肿瘤

人们对PD-1/PD-L1靶向治疗的热情正逐渐降温,部分原因便是该疗法仅在一部分患者中证明有效。为了增加反应率,许多进行中的临床试验均在评估抗PD-1/PD-L1药物与其他免疫治疗方式结合的效果。但是这些结合方式均存在限制。M7824是一种双功能融合蛋白,由抗PD-L1单抗与TGFβ“trap”融合而成。CLIN CANCER RES近期发表了一篇文章,报道M7824治疗晚期实体肿瘤的效果。

JAMA Oncol:PD-L1表达可以预测免疫治疗疗效,PD-L1基因扩增呢?

PD-L1表达是目前公认的免疫检查点抑制剂的疗效预测标志物,那么编码PD-L1蛋白的PD-L1基因扩增是否可以预测实体瘤接受免疫治疗的疗效,PD-L1基因扩增在实体瘤中的发生率是多少?近期发布在《JAMA Oncology》杂志的一项研究在大样本量的覆盖多个瘤种的患者队列中采用全面基因组测序,评估PD-L1基因扩增率,以及扩增患者接受免疫治疗的疗效。

Int Oral Max Surg: 肿瘤PD-L1的表达与年轻女性口腔鳞状细胞癌生存期的改善及复发风险降低有关

年轻口腔鳞状细胞癌患者(OCSCC)通常被认为是一个独特的流行病学队列。在这项研究中,基因组和基于免疫的指标与单一机构治疗的年轻患者的长期结果相关。

Blood:在自然杀伤T细胞淋巴瘤中,STAT3信号通路激活可上调PD-L1的表达!

中心点:在PTCT和NKTL中,JAK/STAT信号通路常发生改变,其中STAT3和TP53是最常见的突变基因。在NKTL中,STAT3激活可促进PD-L1过表达,为STAT3抑制剂与免疫检查点抑制剂结合提供理论基础。摘要:成熟T细胞淋巴瘤,包括外周T细胞淋巴瘤(PTCL)和淋巴结外NK/T细胞淋巴瘤(NKTL),代表了一组异质性的非霍奇金淋巴瘤,治疗方案有限、预后差。为明确JAK/STAT信号通

PD-L1/ CTLA-4免疫联合治疗非小细胞肺癌未能获益

Top-line数据显示与SoC相比,Imfinzi/tremelimumab联合治疗未能显示出无进展生存期(PFS)和总生存期(OS)的统计学显著的改善。但阿斯利康表示Imfinzi单药治疗与化疗相比确实显示出具有临床意义的死亡风险降低。

ASCO速递:PD-L1表达可预测膀胱癌免疫治疗疗效

在经PD-L1抑制剂durvalumab治疗的晚期UC队列中,经回顾性模型分析发现,采用肿瘤细胞(TC)或免疫细胞(IC)上的PD-L1表达≥25%的算法,可筛选出获得最佳临床结果(包括ORR和OS)的患者!(见下表)
