Monitoring molecular residual disease in lung cancer after surgery

Official title: Dynamic Molecular Residual Disease Detection in Stage I-IIIA Non-Small Cell Lung Cancer After Radical Resection

Run by Guangdong Provincial People's Hospital · NCT04976296 · Data updated 2026-11-12

This study looks at patients with early-stage lung cancer who have had surgery to see if testing their blood for leftover cancer DNA can help predict if their cancer will come back.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with histologically confirmed resectable stage I-IIIA NSCLC who have undergone complete resection.

Probably not a fit

Patients with mixed small cell and NSCLC histology or those who have had a history of other malignant tumors within the last 5 years may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study focuses on patients with stage I-IIIA non-small cell lung cancer (NSCLC) who have undergone complete surgical resection. It aims to evaluate the prognostic value of molecular residual disease (MRD) by collecting preoperative blood samples, tumor tissue, and dynamic postoperative blood samples for analysis of circulating tumor DNA (ctDNA). Patients will be followed up every 3 to 6 months to assess disease relapse and the predictive value of MRD in this context.

Why it matters

Potential benefit: If successful, this study could provide a new method for early detection of disease relapse in lung cancer patients post-surgery.

How similar studies have gone: While there is growing interest in MRD evaluation for solid tumors, this specific approach in lung cancer is relatively novel and has not been extensively tested.
