Evaluating Chemotherapy-Free vs Chemotherapy-Containing Combos in First-Line EGFR-Mutated NSCLC: Pros and Cons
Panelists discuss how both chemotherapy-free and chemotherapy-containing combinations offer valuable treatment options for first-line EGFR-mutated non–small cell lung cancer (NSCLC) patients, with considerations including survival benefits, brain metastasis concerns, adverse effect profiles, and the evolution toward personalized treatment selection rather than viewing either approach as universally superior.

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.
