Caspase inhibitor ""Lung cancer is the leading cause of cancer-related death in both males and females in the United States, which is mostly related to smoking. Nonetheless, 25% of all lung cancer cases worldwide (15% of lung cancers in males and 53% in females) are not attributable to smoking (Sun et?al., 2007), which makes?lung cancer in never-smokers an important and common problem. Molecular differences in lung cancers between smokers and never-smokers have been identified. For example, epidermal growth factor receptor (EGFR) mutations, echinoderm microtubule-associated protein-like 4-anaplastic lymphoma Ceritinib kinase fusions, ROS1 rearrangements (CD74-ROS1 fusion), and kinesin family member 5B-ret proto-oncogene fusions are more likely to be identified in never-smokers ( Johnson et?al., 2012). Somatic mutations of EGFR in non-small-cell lung cancer (NSCLC), such as point mutations in exon 21 (e.g., L858R) and exon 19 deletions, are gain of function and enhance autophosphorylation of EGFR, resulting in EGFR-addicted lung cancers that are sensitive to EGFR-specific tyrosine kinase inhibitors (TKIs) ( Sordella et?al., 2004). Although profound responses are observed with EGFR TKIs in patients with the activating somatic EGFR mutations, these therapies are not curative. Continued exposure to EGFR TKIs selects for resistant populations and/or induces EGFR-TKI-resistant mechanisms in tumor cells ( Pao and Chmielecki, 2010). Emergence of tumors with a secondary EGFR mutation in exon 20, T790M, is the most common mechanism of resistance to reversible EGFR TKIs, which is a vexing clinical problem ( Kobayashi et?al., 2005?and?Pao et?al., 2005). Strategies to overcome EGFR TKI resistance by T790M include (1) prevention of emergence of the resistant populations, (2) rechallenge with TKIs after a drug holiday that may allow dilution or disappearance of T790 mutation in the absence of the TKI selection pressure, and (3) treatment of the resistant population with second- or third-generation irreversible EGFR TKIs ( Hirsch et?al., 2013).
