Brief Summary:
The concomitant co-mutation with epidermal growth factor receptor (EGFR) mutation might influence the clinical outcomes. The investigators will identify the impact of concommitant mutation on clinical outcome in patients with advanced -EGFR mutated adenocarcinoma.
The investigators will compare the genetic alterations between tumors of pre and post Tyrosin Kinase Inhibitor(TKI) treatments and predict the resistance mechanism for EGFR-TKIs by next-generation sequencing(NGS) analysis.

Detailed Description:
The current standard therapies in the treatment of advanced EGFR-mutated lung cancer patients are the 1st or 2nd EGFR-TKIs. Although 70-80% of patients treated by EGFR-TKIS show good responses, they have progression after around 12 months. The concomitant co-mutation with EGFR mutation might influence the drug response of EGFR TKI. The investigators will compare the progression-free survival (PFS) of EGFR-TKI according to co-occuring mutations.
The patients experience the change of molecular profiles after using the TKI. Therefore, the investigators will investigate the molecular profiles through NGS panel with foundation medicine in the tissue of pre/post EGFR-TKI, compare the change of the molecular profiles and tumor mutation burden(TMB), and identify novel mechanisms of drug resistance.
The investigators will collect the tumor tissues and blood of around 80 patients in multi-centers prospectively. Then, They will be sent to FoundationOne in the US and perform NGS analysis. The type of EGFR-TKIs would be selected according to physicians' preference. NGS will be performed twice before the EGFR-TKIs treatment and after the progression.
