Background: Mutations affecting the epidermal growth factor receptor (EGFR) are good predictors of clinical efficacy of EGFR tyrosine kinase inhibitors (TKI) in patients with non-small cell lung cancer. Serum carcinoembryonic antigen (CEA) levels are also regarded as predictive for the efficacy of EGFR-TKI and EGFR gene mutations. This study analyzed the association between EGFR gene mutations and clinical features, including serum tumor marker levels in lung adenocarcinomas patients. Patients and Methods: A total of 70 lung adenocarcinoma patients with complete clinical data and pathological specimens were investigated. EGFR gene mutations at exons 19 and 21 were assessed. Serum tumor markers were detected by protein chip-chemiluminescence at the corresponding time, and correlations were analyzed. Results: Mutations of the EGFR gene were detected in 27 of the 70 patients and the serum CEA and CA242 concentrations were found to be significantly associated with the incidence of EGFR gene mutations (P<0.05). The AUCs for CEA and CA242 were 0.724 (95% CI: 0.598~0.850, P<0.05) and 0.769 (95% CI: 0.523~0.800, P<0.05) respectively. Conclusions: Serum CEA and CA242 levels are associated with mutations of the EGFR gene in patients with lung adenocarcinomas.
