Longitudinal analysis of lung cancer using tissue and blood samples.

Establishing a Longitudinal Cohort Study of Lung Cancer Using Tissue and Peripheral Blood Metabolomics to Explore Biomarkers and Therapeutic Mechanisms.

Observational The First Affiliated Hospital of Guangzhou Medical University · NCT06843707

This study is trying to see if changes in blood and tissue samples from lung cancer patients can help doctors tell the difference between harmless and harmful lung nodules and improve treatment plans.

What this trial studies

This observational study aims to establish a longitudinal cohort of lung cancer patients by analyzing tissue and peripheral blood samples for metabolomics. It will focus on key treatment time points, including initial screening for lung nodules, postoperative evaluations, and therapeutic monitoring. The goal is to identify metabolic alterations that could serve as biomarkers for distinguishing between benign and malignant lung nodules, predicting treatment efficacy, and assessing long-term prognosis. By uncovering the underlying metabolic mechanisms, the study seeks to enhance personalized management of lung cancer.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-75 with lung nodules confirmed by CT examination and good preoperative pulmonary function.

Not a fit: Patients with severe respiratory disorders or significant imaging artefacts in CT scans may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic and prognostic tools for lung cancer patients.

How similar studies have performed: Other studies utilizing metabolomics in cancer research have shown promise, indicating potential for success in this approach.
