Abstract:
The most common driver gene mutation in patients with non-small-cell lung cancer (NSCLC) is an epidermal growth factor receptor (EGFR) mutation. With the introduction of EGFR-tyrosine kinase inhibitors, the treatment prospects and prognosis of NSCLC patients with EGFR-sensitive mutations have significantly improved. Nonetheless, therapies targeting NSCLC are still associated with a risk of primary or secondary nonclassical drug resistance mutations. In recent years, the research and methodology have led to the continuous discovery of new drugs and drug resistance targets. These explorations have also resulted in continuously discovering new drugs. Consequently, rapid advancements have been made to overcome NSCLC drug resistance. This study aimed to review the current dilemma of targeted therapy for EGFR mutation-positive NSCLC and the coping strategies for these difficulties.
Insights
Epidermal growth factor receptor (EGFR) mutations drive non-small-cell lung cancer (NSCLC). While targeted therapies improve outcomes, drug resistance remains a challenge, prompting research into new strategies to overcome resistance in EGFR-mutated NSCLC.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Epidermal growth factor receptor (EGFR) mutations are the most frequent driver mutations in non-small-cell lung cancer (NSCLC).
- EGFR-tyrosine kinase inhibitors (TKIs) have significantly improved treatment outcomes for patients with EGFR-sensitive mutations.
- Despite advances, primary and secondary drug resistance mutations remain a significant clinical challenge in EGFR-mutated NSCLC.
Purpose of the Study:
- To review the current challenges in targeted therapy for EGFR mutation-positive NSCLC.
- To explore emerging coping strategies and novel drug targets to overcome resistance.
- To provide an overview of the evolving landscape of NSCLC treatment resistance.
Main Methods:
- Literature review of recent research on EGFR mutations in NSCLC.
- Analysis of drug resistance mechanisms and emerging therapeutic targets.
- Synthesis of current strategies to combat nonclassical drug resistance.
Main Results:
