Epidermal growth factor receptor tyrosine kinase inhibitor for the treatment of non-small cell lung cancer in the past 30 years (1997-2026).

Journal: Chinese medical journal

This systematic review traces nearly three decades of development of EGFR-targeted therapy in NSCLC, focusing on how successive generations of EGFR tyrosine kinase inhibitors have reshaped management of EGFR‑mutant disease.

Key points:

  • Therapeutic evolution:

    The review outlines progression from:

    • First‑generation reversible TKIs (gefitinib, erlotinib, icotinib)
    • Second‑generation irreversible pan‑HER TKIs (afatinib, dacomitinib)
    • Third‑generation, mutation‑selective TKIs (e.g., osimertinib, aumolertinib, furmonertinib, befotertinib, rezivertinib, rilertinib, limertinib, lazertinib, mifanertinib) targeting sensitizing mutations and T790M
    • Newer context-specific agents, including sunvozertinib for exon 20 insertions and zorifertinib for patients with brain metastases
  • Expansion across the disease continuum:

    EGFR-TKIs have moved from use solely in advanced/metastatic settings to broader roles, including:

    • Perioperative settings (neoadjuvant/adjuvant)
    • Maintenance and longer‑term disease control strategies
  • Combination strategies:

    The review summarizes how combining EGFR-TKIs with other modalities has expanded treatment options and contributed to improvements in survival and quality of life, including combinations with:

    • Chemotherapy
    • Anti‑angiogenic therapy
    • Other targeted approaches
  • Ongoing challenges:

    Despite major gains, acquired resistance remains a central barrier to durable control. The article discusses known resistance mechanisms and the need for next‑generation agents and rational combinations to overcome them.

  • Future directions:

    The authors highlight emerging therapies and anticipated developments through 2026, emphasizing:

    • Continued personalization of treatment
    • Better management of CNS disease
    • Strategies to delay or circumvent resistance

Overall, the publication provides a historical and forward-looking overview of EGFR-TKI therapy in NSCLC, underscoring its transformation into a foundational component of care for EGFR‑mutant disease while identifying resistance and long‑term disease control as the key remaining unmet needs.
