Recurrence-free survival (RFS) and overall survival (OS) of cancers with EGFR exon 18 mutations.
KaplanāMeier survival curves for RFS (A) and OS (B) analyses between classic activating mutations and exon 18 mutations. KaplanāMeier survival curves for RFS (C) and OS (D) analyses among single exon 18 mutations (indicated as āexon 18 onlyā), complex exon 18 mutations (indicated as āexon 18ā+āXā) and classic mutations. The log-rank test is used.
