摘要: Data on non-small-cell lung cancer (NSCLC) patients with non-classic epidermal growth factor receptor (EGFR) mutations are scarce, especially in non-Asian populations. The purpose of this study was to evaluate prevalence, clinical characteristics and outcome EGFR-TKI treatment according type EGFR mutation a Dutch cohort NSCLC patients. We retrospectively evaluated 240 EGFR-mutated demographics, tumour-related features, were collected compared between classic mutations, exon 20 insertions other uncommon mutations. Classic detected 186 (77.5%) 54 (22.5%); 23 an insertion (9.6%) 31 (12.9%). Median progression-free survival (PFS) overall (OS) 2.9 9.7 months, respectively, for insertion, 6.4 20.2 mutation. Patients double that included G719X/L861Q/S768I had longer PFS OS single (both P=0.02). In our cohort, prevalence genotype distribution accordance previously reported data. shorter but varied among different
