Abstract
Lung cancer is a heterogeneous disease, and the availability of comprehensive genomic
profiling has allowed for the characterization of its molecular subtypes. This has
increased the ability to deliver “personalized medicines” by tailoring therapies to
target driver mutations in a patient's cancer. The development of targeted therapies
for non-small cell lung cancer (NSCLC) has helped define the era of precision medicine
throughout oncology. This article aims to contextualize recent research and provide
an updated summary of targeted therapies available for patients with NSCLC. With practitioners
and clinical researchers in mind, we note standard of care therapies, important approvals,
practice guidelines, and treatments in development. The first section discusses mutations
in the epidermal growth factor receptor (EGFR) gene, and the second section examines rearrangements in the anaplastic lymphoma
kinase (ALK) and ROS1 fusions. Finally, we explore the rarer molecular alterations in BRAF, RET, MET, HER2, and KRAS. Given the many available therapies, it is important to understand the molecular
alterations in NSCLC, and how to target them.
