Design outcomes

Primary

MeasureTime frame
To investigate the correlation between the serum marker analysis and the clinical data such as response rate, disease control rate, overall survival and progression free survival for previously treated NSCLC patients with and without EGFR Mutation.

Secondary

MeasureTime frame
To acquire the additional information on possible correlation between serum marker analysis and EGFR mutation status in previously treated NSCLC patients.
