Liquid Biopsy Using Methylation Sequencing for Lung Cancer

Completed
Conditions
Lung Cancer
Diagnoses Disease
Interventions
Diagnostic Test: Circulating Tumor DNA Methylation Sequencing
Registration Number
NCT04253509
Lead Sponsor
Samsung Medical Center
Brief Summary

This study aims to investigate the utility of circulating tumor DNA (ctDNA) methylation sequencing in the diagnosis of primary lung cancer.

Detailed Description

Plasma sample of patients with and without lung cancer will be collected and analyzed using methylation-sensitive enzyme sequencing method. Diagnostic performance of ctDNA methylation sequencing will be compared with that of tumor markers (CEA, Cyfra 21-1, and NSE) combined.
