JCO:恶性间皮瘤肿瘤易感基因的突变频率

2018-08-21 MedSci MedSci原创

JCO近期发表了一篇文章,研究恶性间皮瘤(MM)患者的肿瘤易感突变情况。作者对198例胸膜、腹膜及睾丸鞘膜恶性间皮瘤患者进行了针对85个肿瘤易感基因的二代测序。

JCO近期发表了一篇文章,研究恶性间皮瘤(MM)患者的肿瘤易感突变情况。作者对198例胸膜、腹膜及睾丸鞘膜恶性间皮瘤患者进行了针对85个肿瘤易感基因的二代测序。

娅就结果表明,198例患者中23例发现了13个基因的24个突变。其中BAP1是最常见的突变。其余的突变存在于与DNA损伤敏感和修复、氧敏感、胞内运输和细胞生长有关的基因中。胸膜原发、石棉暴露以及更大的年龄与携带突变可能降低有关,而继发癌症诊断显着增加该可能性。恶性间皮瘤患者与无肿瘤对照人群相比,携带BAP1、BRCA2、CDKN2A、TMEM127、VHL和WT1突变的可能更高。在52%(29 of 54)的患者中发现了同源重组通路基因突变。

文章最后认为,恶性间皮瘤患者中有相当一部分携带有肿瘤易感基因的突变,尤其是胸膜恶性间皮瘤、石棉暴露少、更年轻以及继发肿瘤诊断的患者。这些结果支持对恶性间皮瘤患者进行基因检测,为恶性间皮瘤中同源重组通路的研究提供信息。

姜黄素或可有效抵御恶性间皮瘤的发展
