EGFR and non-small cell lung carcinoma: Our findings indicate that Chinese and Japanese patients with EGFR-mutant NSCLC who carry the BIM deletion polymorphism have an inferior progression-free survival compared to those who do not (Chinese: HR = 1.607, 95% CI = 1.251–2.065, P = 0.0002; Japanese: HR = 2.636, 95% CI = 1.603–4.335, P = 0.0001).
