Cancer Discov.:PI3K畸变致使鳞状细胞肺癌向脑转移

2015-05-06 范伟译 MedSci原创

背景:鳞状细胞肺癌(SQCLC)大规模基因组的特征揭示了一些公认的致瘤机制。然而,没有数据表明这些变化有临床意义。方法:我们对79名IV阶段的鳞状细胞肺癌患者SQCLCs(包括下一代测序) 进行全面的基因组分析,分析两个主要SQCLC亚型:FGFR1增殖和PI3K畸变在临床特征上的差异。结果:PI3K异常的肿瘤患者的疾病有侵入性致使生存期更糟(总生存期OS 中位数8.6 vs 19.1,p <

背景:鳞状细胞癌(SQCLC)大规模基因组的特征揭示了一些公认的致瘤机制。然而,没有数据表明这些变化有临床意义。

方法:我们对79名IV阶段的鳞状细胞肺癌患者SQCLCs(包括下一代测序) 进行全面的基因组分析,分析两个主要SQCLC亚型:FGFR1增殖和PI3K畸变在临床特征上的差异。

结果:PI3K异常的肿瘤患者的疾病有侵入性致使生存期更糟(总生存期OS 中位数8.6 vs 19.1,p < 0.001),转移的风险更高(> 3个器官18% vs 3%,p = 0.025)和脑转移发病率更大(27% vs 0%,p < 0.001)。对成对的脑转移和原发性肺癌的患者进行全外显子和RNA测序,阐明癌向大脑转移的过程。

结论:鳞状细胞SQCLC的初选导致的脑转移表明躯干抑癌基因的缺失。SQCLC脑转移表明了高度的遗传异质性和克隆具有差异性的证据。
