Abstract:

Objective To explore the relationship of treatment effects between the correlation of carcinoembryonic antigen(CEA), carbohydrate antigen 125(CA125), cytokeratin 19 fragment antigen 21-1(CYFRA21-1) level and clinical effect of epidermal growth factor receptor-tyrosine kinase inhibitors(EGFR-TKIs) for lung adenocarcinoma patients with epidermal growth factor receptor (EGFR) mutation. Methods One hundred and eighty six patients with EGFR mutations of advanced non-small cell lung cancer(NSCLC) from our hospital were selected. The first generation of EGFR-TKIs was used for therapy, and the correlation between CEA, CA125, CYFRA21-1 level before treatment and progression-free survival(PFS), overall survival(OS) was analyzed. Results The median PFS and OS of 186 lung adenocarcinoma patients receiving EGFR-TKIs treatment after treatment were 8.8 months and 22.9 months respectively, and the median PFS and OS of lung adenocarcinoma patients with high CEA level (13.2 months, 26.7 months) were better than those of patients with normal CEA level (8.1 months, 12.8 months), the median PFS and OS of patients with elevated CA125 level (13.5 months, 26.8 months) were better than those of patients with normal CA125 level (8.2 months, 12.4 months), the median PFS and OS of patients with normal CYFRA21-1 level (12.8 months, 25.8 months) were better than those of patients with elevated CYFRA21-1 level (8.3 months, 13.5 months)(P<0.05). Conclusion It is positive predictors for evaluating the efficacy of EGFR-TKIs, that the elevated levels of CEA and CA125 and normal levels of CYFRA21-1 in patients with EGFR-mutant lung adenocarcinoma.
