简要总结
The goal of this study is to evaluate the clinical utility of a personalized, WES-informed MRD detection approach in patients with early-stage non-small cell lung cancer, with a focus on its association with postoperative recurrence and prognosis, as well as its ability to predict recurrence earlier than imaging.
详细描述
Background:
Non-small cell lung cancer (NSCLC) is associated with a high risk of postoperative recurrence despite curative-intent surgery. Minimal residual disease (MRD) detection using circulating tumor DNA (ctDNA) has emerged as a promising approach for early identification of molecular relapse. Tumor-informed strategies based on whole-exome sequencing (WES) enable personalized MRD monitoring with improved sensitivity and specificity.
Objective:
To evaluate the clinical utility of a personalized, WES-informed MRD detection approach in patients with early-stage NSCLC, focusing on its association with postoperative recurrence and prognosis, its ability to predict recurrence earlier than imaging, and its role in assessing treatment efficacy.
