Abstract:
Lung cancer treatment has changed in the last twenty years since the discovery of EGFR mutations. In this article, we will review the current state of the art for non-small cell lung cancer (NSCLC) actionable genomic alterations (AGA). AGAs are mostly found in lung adenocarcinomas, a subtype of non-small cell lung cancers. We will focus on the current treatment for EGFR mutations, ALK fusions, ROS1 fusions, BRAF V600E mutations, MET exon 14-skipping mutations, RET fusions, KRAS G12C mutations, ERBB2 mutations (also called HER2 mutations), and NTRK fusions. We will also touch on the key toxicities associated with these medications. Treatments are mostly available for the metastatic stage, but we will also discuss adjuvant therapy for EGFR mutations and ALK fusions, as well as stage III post-chemoradiotherapy treatment for EGFR lung cancer.
Insights
Targeted therapies for non-small cell lung cancer (NSCLC) have advanced significantly. This review covers actionable genomic alterations (AGAs) like EGFR mutations and their targeted treatments, including adjuvant and stage III options.
Area of Science:
- Oncology
- Genomics
- Molecular Biology
Background:
- The landscape of lung cancer treatment has been revolutionized by the identification of actionable genomic alterations (AGAs).
- Non-small cell lung cancer (NSCLC), particularly lung adenocarcinoma, frequently harbors these AGAs.
- Understanding these alterations is crucial for personalized treatment strategies.
Purpose of the Study:
- To provide a comprehensive review of the current state-of-the-art treatments for specific AGAs in NSCLC.
- To discuss the clinical implications and toxicities of targeted therapies for these alterations.
- To explore treatment options beyond the metastatic setting, including adjuvant and stage III therapies.
Main Methods:
- Literature review of current research and clinical guidelines on actionable genomic alterations in NSCLC.
- Focus on targeted therapies for EGFR, ALK, ROS1, BRAF V600E, METex14, RET, KRAS G12C, ERBB2 (HER2), and NTRK alterations.
- Inclusion of data on treatment efficacy, toxicity profiles, and application in different disease stages.
Main Results:
- Targeted therapies have demonstrated significant efficacy in NSCLC patients with specific AGAs.
- Established treatments exist for EGFR mutations, ALK and ROS1 fusions, BRAF V600E, METex14, RET, KRAS G12C, ERBB2, and NTRK fusions.
- Adjuvant and stage III treatment strategies are emerging for certain AGAs, notably EGFR mutations and ALK fusions.
Conclusions:
- Actionable genomic alterations are key drivers in NSCLC, necessitating molecular profiling for optimal treatment selection.
- Targeted therapies offer improved outcomes for patients with specific AGAs across various disease stages.
- Ongoing research continues to expand therapeutic options and refine treatment approaches for NSCLC.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
