CLIN CANCER RES:循环肿瘤DNA指导晚期肺腺癌治疗

2017-09-11 MedSci MedSci原创

肺癌目前是美国最主要的癌症死亡原因。非小细胞肺癌是最常见的病理类型。尽管早期检测及标准治疗水平均有所提高,但是非小细胞肺癌发现时往往较晚且预后不良。CLIN CANCER RES近期发表了一篇文章,研究非小细胞肺癌患者血液中循环肿瘤DNA(ctDNA)基因改变并与临床特征和治疗结果相联系。

肺癌目前是美国最主要的癌症死亡原因。非小细胞肺癌是最常见的病理类型。尽管早期检测及标准治疗水平均有所提高,但是非小细胞肺癌发现时往往较晚且预后不良。CLIN CANCER RES近期发表了一篇文章,研究非小细胞肺癌患者血液中循环肿瘤DNA(ctDNA)基因改变并与临床特征和治疗结果相联系。作者共分析了88例患者血液中的ctDNA,其中34例患者的肿瘤组织进行了二代测序,29例进行了其他类型的基因分型,25例由于缺乏足够组织或活检禁忌症未进行组织分子检测。研究结果表明,72例患者有≥1 ctDNA改变;这些患者中,75%带有FDA批准的(61.1%)或正在进行临床试验的(13.9%)的潜在突变。最常见的突变为TP53,EGFR,MET,KRAS和ALK基因。带有任意可检测ctDNA改变的患者EGFR改变符合率为80.8%(100% vs 61.5%;ctDNA和组织检测间隔≤1 vs≥1个月)。25例患者根据ctDNA改变接受了相应治疗;72.3%(n=16/22)可评估的匹配治疗患者达到病情稳定≥6个月或出现部分反应。5例ctDNA检测到EGFR T790M的患者接受三代EGFR抑制剂

CMGH:新型肝癌DNA检测手段或改善患者生存率

一篇发表于国际杂志Cellular and Molecular Gastroenterology and Hepatology上的研究论文中,来自广岛大学的研究人员通过研究表示,对患者手术前血清样本中的循环肿瘤DNA进行检测或可帮助预测患者肝细胞癌的早期复发以及帮助指导疗法的进行;肝细胞癌是一种常见类型的肝癌,其也是世界上引发癌症死亡的主要癌症。研究者Atsushi Ono教授表示,我们发现,循环

NEJM:循环肿瘤DNA监测转移性乳腺癌潜力巨大

转移性乳腺癌的治疗需要监测肿瘤负荷以明确治疗应答,并且还需要改善生物标志物,如癌抗原15-3(CA 15-3)和循环肿瘤细胞。这类生物标志物已得到广泛研究。然而,对于乳腺癌,携带有肿瘤特异性变异的循环游离细胞DNA(循环肿瘤DNA)尚未得到充分的研究,或尚未与其他循环生物标志物进行比较。英国剑桥大学和英国癌症研究(中心)剑桥研究所李嘉诚中心肿瘤科的Sarah-Jane博士等人对此进行了深入研究,他
