| Description | Background: Tumor biomarkers are used for predicting therapy effect and prognosis of patients with non-small cell lung cancer (NSCLC). We focused on their potential role in prediction of the efficacy of erlotinib. Patients and Methods: In a total of 144 patients with advanced-stage (IIIB or IV) NSCLC treated with erlotinib, pre-treatment levels of soluble carcinoembryonic antigen (CEA) and cytokeratin markers in serum were measured. Results: The median progression-free and overall survival for patients with a high level of carcinoembryonic antigen (CEA) was 1.9 and 8.6 vs. 2.9 and 16.1 months for patients with low CEA (p=0.046 and p=0.116). The respective medians for patients with a high level of cytokeratin-19 fragment were 1.9 and 6.1 vs. 3.4 and 23.8 months for patients with the low cytokeratin-19 fragment (p<0.001 and p<0.001). Conclusion: High pre-treatment serum levels of one or both biomarkers are associated with poor outcome of patients with NSCLC treated with erlotinib. |
