This study includes a total of 60 multiple myeloma patients, and peripheral blood will be collected at newly diagnosed, remission after 4 cycles of therapy, and, relapse stage.

10 mL of peripheral blood will be drawn from 60 multiple myeloma patients at diagnosis, 4 months post-induction, and at relapse, and cell-free DNA is then extracted and undergo bisulfite methylation sequencing.

1. To carry out research on minimal residual disease (MRD) monitoring in patients with multiple myeloma (MM) based on plasma circulating tumor DNA (ctDNA) methylation sequencing, which aims to explore new MRD detection methods for MM;
2. Carry out ctDNA-based methylation sequencing in newly diagnosed, remission, and, relapsed MM patients, to track the clonal evolution patterns; and explore the in the initial diagnosis-remission-relapse stage of MM, track the clonal evolution characteristics of methylation profiles in MM patients during the disease progression.

Circulating Tumor DNA Methylation Sequencing

Sang-Won Um, MD, PhD

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

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.

Clinical Utility of Circulating Tumor DNA Methylation in the Diagnosis of Primary Lung Cancer

Using pathologic diagnosis of lung cancer as gold standard, diagnostic sensitivity of ctDNA methylation will be compared with that of tumor markers.

Using pathologic diagnosis of lung cancer as gold standard, diagnostic specificity of ctDNA methylation will be compared with that of tumor markers.

Using pathologic diagnosis of lung cancer as gold standard, diagnostic accuracy of ctDNA methylation will be compared with that of tumor markers.

Using pathologic diagnosis of lung cancer as gold standard, positive predictive value of ctDNA methylation will be compared with that of tumor markers.

Using pathologic diagnosis of lung cancer as gold standard, negative predictive value of ctDNA methylation will be compared with that of tumor markers.
