Overview
Brief Summary
Circulating tumor DNA (ctDNA) is a promising biomarker for noninvasive assessment of cancer burden. In this study, PEAC (Personalized Analysis of Cancer) technology was performed to detect the driver gene mutations from plasma samples and matched tumor tissue samples were detected by NGS platform at baseline. Investigators also applied ctDNA dynamic monitoring using PEAC technology in early stage NSCLC patients with driver mutations positive at baseline, to evaluate the feasibility and their potential clinical application.
Detailed Description
Circulating tumor DNA (ctDNA) is a promising biomarker for noninvasive assessment of cancer burden. Advances in DNA sequencing technologies and our understanding of the molecular biology of tumours have resulted in increased interest in exploiting ctDNA as a tool to facilitate earlier detection of cancer and thereby improve therapeutic outcomes by enabling early intervention. In this study, PEAC (Personalized Analysis of Cancer) technology was performed to detect the driver gene mutations from plasma samples and matched tumor tissue samples were detected by NGS platform at baseline. Investigators aim to evaluate whether driver gene mutations detected by PEAC can replace tissue testing results in patients with stage I to Ⅲ NSCLC. Investigators also applied ctDNA dynamic monitoring using PEAC technology in early stage NSCLC patients with driver mutations positive at baseline, to evaluate the feasibility and their potential clinical application.
