不吸烟者的肺癌是一种重要的疾病,通常以EGFR突变为特征,但降低风险的措施和有效的化学预防策略尚未建立。我们发现mTOR是EGFR突变肺癌的一个新的潜在有价值的靶点,因为mTOR在EGFR突变的人肺癌中被激活,随着T790M突变的获得而增加。在EGFR突变型肺癌小鼠模型中,mTOR的激活是一个早期事件。作为单一药物,mTOR抑制剂雷帕霉素可以阻止肿瘤发展,延长总生存期,并改善不可逆EGFR TKI治疗后的预后。这些研究支持mTOR抑制剂的临床试验,以防止EGFR突变肺癌的发生和进展。
Lung cancer in never-smokers is an important disease often characterized by mutations in EGFR, yet risk reduction measures and effective chemopreventive strategies have not been established. We identify mTOR as a new and potentially valuable target for EGFR mutant lung cancer, as mTOR was activated in human lung cancers with EGFR mutations, which increased with acquisition of T790M mutation. In a mouse model of EGFR mutant lung cancer, activation of mTOR was an early event. As a single agent, the mTOR inhibitor rapamycin, prevented tumor development, prolonged overall survival, and improved outcomes after treatment with an irreversible EGFR TKI. These studies support clinical testing of mTOR inhibitors to prevent the development and progression of EGFR mutant lung cancers.
