Using blood tests to detect ovarian cancer through DNA analysis

ctDNA Methylation Testing for Detecting Epithelial Ovarian Cancer: A Prospective Multicenter Cohort Study (OVAMethy Study)

Observational Peking Union Medical College Hospital · NCT05801263

This study is testing whether a blood test that looks at DNA changes can help find ovarian cancer earlier than current methods.

What this trial studies

This observational study focuses on the early detection of epithelial ovarian cancer by analyzing the methylation status of specific genes (CDO1 and HOXA9) in cell-free DNA extracted from blood samples. Participants will undergo blood collection and histological sampling based on clinical indications, with a follow-up period of 12 months to monitor symptoms and treatment outcomes. The study aims to validate the effectiveness of this non-invasive diagnostic method compared to traditional histopathological analysis.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 18 and older with pathological ovarian results who are not currently undergoing chemotherapy or surgical treatment.

Not a fit: Patients without ovarian pathology or those who are currently receiving treatment for ovarian lesions may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve early detection rates of ovarian cancer, leading to better patient outcomes.

How similar studies have performed: Previous studies have shown promising results in using DNA methylation as a biomarker for ovarian cancer detection, indicating potential success for this approach.
