Abstract:
Despite recent progress in the treatment on non-small cell lung cancer (NSCLC), outcomes remain suboptimal. Treatment advances that target the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor (VEGF) signaling pathways highlight the need to understand the multiple convergent growth factor signaling pathways involved in the pathogenesis of NSCLC. Signaling through fibroblast growth factors (FGF), long recognized for its pro-angiogenic activity, has recently emerged as a contributing factor in the pathogenesis and progression of NSCLC through an autocrine signaling loop. In addition, this pathway may function as a mechanism of resistance to anti-EGFR and anti-VEGF treatment. Clinical experience with FGF receptor (FGFR) inhibitors is mounting, and more specific inhibitors of this signaling pathway are in development. This review describes the structure of the FGF signaling pathway, delineates its dual roles in angiogenesis and proliferation in NSCLC, evaluates FGF ligand and receptor expression as prognostic biomarkers in NSCLC, and discusses the development of FGF pathway inhibitors for the treatment of lung malignancies.
Insights
Fibroblast growth factor (FGF) signaling drives non-small cell lung cancer (NSCLC) growth and resistance to targeted therapies. Targeting the FGF pathway offers a promising strategy for improving NSCLC treatment outcomes.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Therapeutics
Background:
- Non-small cell lung cancer (NSCLC) treatment outcomes remain suboptimal despite advances targeting EGFR and VEGF pathways.
- Emerging evidence implicates fibroblast growth factor (FGF) signaling in NSCLC pathogenesis, progression, and resistance to existing therapies.
Purpose of the Study:
- To review the structure and function of the FGF signaling pathway in NSCLC.
- To evaluate the role of FGF signaling in angiogenesis and proliferation in NSCLC.
- To discuss FGF pathway inhibitors as a therapeutic strategy for NSCLC.
Main Methods:
- Literature review of studies on FGF signaling in NSCLC.
- Analysis of FGF ligand and receptor expression as prognostic biomarkers.
- Evaluation of clinical development of FGF receptor (FGFR) inhibitors.
Main Results:
- FGF signaling contributes to NSCLC pathogenesis through autocrine loops, promoting angiogenesis and proliferation.
- FGF pathway activation may mediate resistance to anti-EGFR and anti-VEGF therapies.
- FGF ligand and receptor expression show potential as prognostic biomarkers in NSCLC.
Conclusions:
- The FGF signaling pathway is a critical driver in NSCLC and a potential mechanism of therapeutic resistance.
- Targeting FGFR with specific inhibitors is a promising therapeutic avenue for NSCLC treatment.
- Further research into FGF pathway modulation is warranted for improved lung cancer therapies.
