ctDNA to help treat oligometastatic cancer with local ablation
Official title: Clinical Utility of ctDNA in the Treatment of Oligometastatic Disease - A Prospective Observational Clinical Study - A Part of the POB-project
Run by Aarhus University Hospital · NCT07426250 · Data updated 2026-11-12
This study tests whether blood-tested ctDNA can predict outcomes and guide follow-up for people with oligometastatic cancer who are receiving local ablative treatment.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with oligometastatic solid tumors planned for definitive-intent local ablative therapy.
✕Probably not a fit
Patients whose disease biology does not yield detectable ctDNA or whose cancer biology does not align with LAT outcomes may not benefit from ctDNA insights in this study.

What this trial studies
This is a prospective observational study that looks at ctDNA levels before, during, and after local ablative therapy for oligometastatic solid tumors. Researchers will collect serial blood samples and use archival tumor tissue to analyze ctDNA and total cfDNA, aiming to see how ctDNA relates to residual disease, recurrence, and survival. The goal is to determine ctDNA detection rates, how ctDNA changes after treatment, and whether it can serve as a prognostic and response biomarker across tumor types and LAT modalities.
Why it matters
Potential benefit: If successful, ctDNA monitoring could help predict recurrence earlier and tailor follow-up and treatment decisions for patients.
How similar studies have gone: Prior studies and pilot data suggest ctDNA dynamics are associated with treatment outcomes, supporting exploration in this setting.
