No statistical difference was shown in progression-free survival (PFS) among uncommon epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC) patients treated by first-line epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and platinum-based chemotherapy. (A) PFS of all uncommon EGFR-mutated NSCLC patients treated by first-line EGFR-TKIs and platinum-based chemotherapy; (B) PFS of NSCLC patients harboring G719X mutation treated by first-line EGFR-TKIs and platinum-based chemotherapy; (C) PFS of NSCLC patients harboring L861Q mutation treated by first-line EGFR-TKIs and platinum-based chemotherapy; (D) PFS of NSCLC patients harboring doublet uncommon EGFR mutations treated by first-line EGFR-TKIs and platinum-based chemotherapy.
