Using mitochondrial DNA in blood to monitor liver cancer recurrence

Evaluation of Circulating Tumor Mitochondrial DNA (ct-mtDNA) As a Biomarker for Minimal Residual Disease (MRD) Assessment and Recurrence Monitoring in Hepatocellular Carcinoma (HCC)

Observational Tongji Hospital · NCT06653062

This study is testing if looking at mitochondrial DNA in the blood can help doctors track liver cancer recurrence in patients after treatment.

What this trial studies

This observational study aims to evaluate the effectiveness of circulating tumor mitochondrial DNA (ct-mtDNA) as a biomarker for assessing minimal residual disease (MRD) and monitoring recurrence in patients with hepatocellular carcinoma (HCC). Conducted at Tongji Hospital in Wuhan, China, the study will collect and analyze plasma samples from HCC patients to detect mitochondrial mutations before and after treatment. The primary goal is to determine how MRD status impacts progression-free survival, while secondary objectives include examining the correlation between MRD markers and treatment outcomes. The study hypothesizes that ct-mtDNA dynamics are linked to recurrence risk and overall survival in HCC patients.

Who should consider this trial

Good fit: Ideal candidates are patients diagnosed with hepatocellular carcinoma who meet specific inclusion criteria and have measurable lesions.

Not a fit: Patients with other active tumors or insufficient tumor tissue for MRD detection may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a novel method for early detection of liver cancer recurrence, potentially improving patient outcomes.

How similar studies have performed: While the use of ct-mtDNA as a biomarker is a relatively novel approach, similar studies have shown promise in other cancer types, indicating potential for success.
