Patients with EGFR-mutant lung adenocarcinomas (LUADs) who initially respond to first-generation tyrosine kinase inhibitors (TKIs) develop resistance to these drugs. A combination of the irreversible TKI afatinib and the EGFR antibody cetuximab can be used to overcome resistance to first-generation TKIs; however, resistance to this drug combination eventually emerges. We identified activation of the mTORC1 signaling pathway as a mechanism of resistance to dual inhibition of EGFR in mouse models. The addition of rapamycin reversed resistance in vivo. Analysis of afatinib-plus-cetuximab-resistant biopsy specimens revealed the presence of genomic alterations in genes that modulate mTORC1 signaling, including NF2 and TSC1. These findings pinpoint enhanced mTORC1 activation as a mechanism of resistance to afatinib plus cetuximab and identify genomic mechanisms that lead to activation of this pathway, revealing a potential therapeutic strategy for treating patients with resistance to these drugs. 8 `2 o) M0 N* P, |2 s6 O( L9 e4 q2 Y: v

草船哥，您好，我爸爸服用台湾版2992已经十天，胸痛和背痛得到缓解，可能是有效的，但是口腔溃疡和腹泻比 ...

十分谢谢，我准备让他明后天停两天2992，恢复一下，2992的副作用还是比易瑞沙大的多。另外，我想给他买点大豆胜肽补充点营养，就是台湾陈月卿推荐的那个类似蛋白粉的东西，但是又听有人说肺癌不能吃蛋白粉，应该吃速愈素，不知道您家吃过这些东西没有。以前我爸爸吃了两年虫草两年孢子油还有医生开的康乃特，论坛说吃靶向药不能同时服用中药，所以都停了，现在什么都没吃又心慌，现在食欲没以前好，总想给他补充点体力。
