Circulating Tumor Mitochondrial DNA (ct-mtDNA) As a Biomarker for Biliary Tract Cancer Recurrence Surveillance

NCT06653127 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 50

Last updated 2024-12-30

No results posted yet for this study

Summary

This is a prospective, observational, single-center study. The purpose of this study is to evaluate the efficacy of circulating tumor mitochondrial DNA (ct-mtDNA) in plasma as a biomarker for minimal residual disease (MRD) assessment and recurrence monitoring in patients with biliary tract cancer.

Conditions

  • Biliary Tract Cancer

Interventions

OTHER

Plasma and Tumor Tissue Mitochondrial DNA (mtDNA) Mutation Analysis

Targeted Analysis of Mitochondrial Mutations: Unlike many interventions that may focus on nuclear DNA or general tumor markers, this intervention specifically analyzes mutations within the mitochondrial genome. This focus on mtDNA is based on evidence suggesting that mtDNA mutations are more frequent and may serve as more sensitive indicators of minimal residual disease (MRD) in cancer patients. Liquid Biopsy Approach: The intervention utilizes a liquid biopsy technique, which involves the collection and analysis of peripheral blood samples to detect circulating tumor DNA (ctDNA). This non-invasive method contrasts with traditional tissue biopsy interventions, offering a less intrusive approach to monitor disease progression and recurrence.
