Tumor-informed MRD for Non-small Cell Lung Cancer
An Observational Study on the Prediction of Recurrence Risk in Early-stage Non-small Cell Lung Cancer Using a Customized MRD Monitoring Scheme Based on Tumor Tissue WES
연구 개요
상태
상세 설명
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.
Methods:
This is a single-center, prospective, observational study enrolling 450 patients with newly diagnosed stage IIB-III NSCLC undergoing surgical treatment. Tumor tissue and matched blood samples will undergo WES to identify patient-specific somatic mutations for the development of individualized MRD panels. Serial plasma samples will be collected at predefined time points before and after surgery, during neoadjuvant/adjuvant therapy, and throughout follow-up. MRD status will be dynamically monitored using ctDNA analysis.
Endpoints:
The primary endpoint is recurrence-free survival (RFS). Secondary endpoints include lead time between MRD detection and imaging-confirmed recurrenceand correlation between MRD status and treatment outcomes.
