Role of Rebiopsy at Disease Progression in EGFRm NSCLC

Panelists discuss how second-line therapy after osimertinib monotherapy depends on resistance mechanisms. If MET amplification, consider MET inhibitors plus EGFR tyrosine kinase inhibitors (TKIs). For C797S mutation, potential options include first- or third-generation EGFR TKI combinations. Chemotherapy remains a key fallback.
