Comparative clinical outcomes for patients with advanced NSCLC harboring EGFR exon 20 insertion mutations and common EGFR mutations
Lung Cancer(2021)
Abstract
•Median rwOS was 16.2 months for EGFR exon20ins vs 25.5 months for cEGFR (p < 0.0001).•Median rwPFS was 2.9 months for EGFR exon20ins vs 10.5 months for cEGFR (p < 0001).•Platinum-based chemotherapy was most common 1L therapy for EGFR exon20ins (61.3%).•EGFR exon20ins has poor prognosis, with little benefit from EGFR TKI treatment.
