First-Line Treatment Options for EGFR-Mutated NSCLC: Chemotherapy-Free vs Chemotherapy-Containing Combinations

Both chemotherapy-free and chemotherapy-containing combinations represent significant advancements over earlier monotherapies for patients with EGFR-mutated NSCLC. The availability of multiple effective options allows for personalized treatment approaches.

Key Considerations

• Multiple Effective Regimens: The data supports 3 treatment options for patients with EGFR-mutated disease, providing physicians and patients with meaningful choices.
• Patient Priorities: Patients typically prioritize:
  • Overall survival benefit
  • Central nervous system control/brain metastasis prevention
  • Quality of life
• Treatment Selection Factors:
  • MARIPOSA trial data is more mature with established progression-free survival benefit; final overall survival data is pending.
  • FLAURA2 offers another effective option in the first-line setting.

Chemotherapy-Free vs Chemotherapy-Containing Regimens

Similarities:

• Both approaches require intravenous therapy administration.
• Both regimens demonstrate clear superiority to earlier single-agent treatments.

Differences:

• Chemotherapy has specific toxicities, including myelosuppression and alopecia.
• Nonchemotherapy regimens have their own adverse event profiles.

Clinical Perspective

Rather than viewing the decision as treatment escalation, physicians should consider the possibility of de-escalation in the appropriate patients. The choice between regimens should be guided by the following:

• Patient-specific factors
• Clinical characteristics
• Performance status
• Comorbidities

Modern supportive care has significantly reduced traditional chemotherapy adverse effects such as severe nausea and vomiting, making toxicity profiles more comparable between approaches.
