• Background EGFR mutated lung cancer represents a subgroup with distinct clinical presentations, prognosis, and management requirements. We investigated the survival, prognostic factors, and real-world treatment of NSCLC patients with EGFR mutation in clinical practice. Methods A retrospective review of all specimens sent for EGFR analysis from December 2009 to September 2015 was performed. Patient demographics, specimen type, EGFR mutation status/type, stage at diagnosis, treatment, response rate, and survival data were recorded. Results 27/334 (8%) patient specimens sent for EGFR testing tested positive for a sensitising EGFR mutation. The median age was 65 years (40–85 years). Exon 19 deletion represented the most commonly detected alteration, accounting for 39% ( n  = 11). First-line treatment for those with Exon 18, 19, or 21 alterations ( n  = 24) was with an EGFR tyrosine kinase inhibitor (TKI) in 79% ( n  = 19). Objective response rate among these patients was 74% and median duration of response was 13 months (range 7–35 months). Conclusion The incidence of EGFR mutation in our cohort of NSCLC is 9% which is consistent with mutation incidence reported in other countries. The rate of EGFR mutation in our population is slightly below that reported internationally, but treatment outcomes are consistent with published data. Real-world patient data have important contributions to make with regard to quality measurement, incorporating patient experience into guidelines and identifying safety signals.
