Detection Cell Free DNA in Lung Cancer Patients
Using Next Generation Sequencing (NGS) Method to Detect Circulating Free DNA (Cf-DNA) and Explore the Resistance and Prognosic Mechanism of Third Generation Epidermal Growth Factor Receptor (EGFR) Tyrosine-kinase Inhibitor (TKI) in Advanced Non-small Cell Lung Cancer (NSCLC) Patients: a Single Center Study

Summary
Brief summary (as posted)
third generation of EGFR-TKIs is the newest target therapy for NSCLC. However, we did not known the specific mechanisms for those non-responders and patients grow resistance.Next generation sequencing is current the most sensitive and specific method to exam gene mutation, diversion etc. By consistently detect the cf-DNA, we could possibly find out the mechanisms of response and resistance.
