ASRs for EGFR mutation-positive NSCLC were higher for females than males: standardised incidence ratio (SIR) 1.50 (1.31–1.73); higher for Pacifica, Asians and Māori compared with New Zealand Europeans: SIRs 3.47 (2.48–4.85), 3.35 (2.62–4.28), and 2.02 (1.43–2.87), respectively; and, only slightly increased in ever-smokers compared with never-smokers: SIR 1.25 (1.02–1.53). This evidence concerns the gene EGFR and non-small cell lung carcinoma.
