Using blood tests to improve ovarian cancer diagnosis

Improved Diagnosis of Ovarian Cancer by Use of Circulating Tumor DNA as a Biomarker

Observational University of Aarhus · NCT05763511

This study is testing whether a blood test that looks for tumor DNA can help doctors better tell if women with suspected ovarian cancer have a serious condition or not before they have surgery.

What this trial studies

This project investigates the use of circulating tumor DNA (ctDNA) in women with suspected ovarian cancer to enhance diagnostic accuracy. The study aims to evaluate the effectiveness of ctDNA alone and in combination with imaging techniques and CA 125 levels for distinguishing between benign and malignant ovarian masses before surgery. Blood and tissue samples will be collected from participants to analyze disease progression and biology, ultimately leading to the development of a more effective diagnostic algorithm.

Who should consider this trial

Good fit: Ideal candidates are women with suspected ovarian neoplasms who can provide informed consent.

Not a fit: Patients with a previous diagnosis of ovarian cancer or those unable to give informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to earlier and more accurate diagnoses of ovarian cancer, improving patient outcomes.

How similar studies have performed: Other studies have shown promise in using ctDNA as a biomarker for various cancers, suggesting potential success for this approach in ovarian cancer diagnostics.
