Analysis of Circulating Tumor DNA Dynamics to Predict and Monitor Response to Tyrosine Kinase Inhibitors in Patients With Advanced Non-small Cell Lung Cancer
This is an observational study, aiming to investigate whether the ctDNA dynamics analyzed by the K-TrackTM assay could predict early response to Tyrosine kinase inhibitors (TKIs) in patients with advanced non-small cell lung cancer (NSCLC). 1. Determine relationship between ctDNA dynamics and clinical response to TKI, * No response/progressive disease = ctDNA levels increase from baseline * Partial response/stable disease = ctDNA levels decrease from baseline * Complete response = ctDNA clearance. 2. Compare and combine ctDNA dynamics and RECIST1.1 to predict clinical response. 3. Determine relationship between ctDNA dynamics and progression free survival, overall survival.
• Patients are diagnosed with advanced non-small cell lung cancer and indicated for TKI (first or second line). TKI combined with chemotherapy is allowed.
• FFPE/FNA sample is available.
• Compliant with treatment protocol.
• Patients consented to participate in the study.
