Detecting ovarian cancer using blood tests for DNA changes

Exploration of Plasma CDO1 and HOXA9 DNA Methylation for Detecting Epithelial Ovarian Cancer: A Clinical Trial in China

Observational Peking Union Medical College Hospital · NCT05801276

This study is testing a new blood test that looks for DNA changes to see if it can help find ovarian cancer earlier in women.

What this trial studies

This observational study aims to improve the early detection of epithelial ovarian cancer through the analysis of circulating tumor DNA (ctDNA) methylation patterns in plasma samples. It consists of two phases: the Clinical Performance Validation phase, which evaluates the effectiveness of assessment reagents against standard histopathological examinations, and the Assay Accuracy Verification phase, which uses Sanger sequencing to compare the accuracy of methylation detection methods. By focusing on non-invasive liquid biopsy techniques, the study seeks to enhance diagnostic capabilities for ovarian cancer, potentially leading to earlier treatment interventions.

Who should consider this trial

Good fit: Ideal candidates include patients aged 18 and older who are preparing for surgical treatment of pelvic or adnexal masses and have not undergone prior chemotherapy or surgery for ovarian lesions.

Not a fit: Patients who are currently receiving chemotherapy, physical therapy, or surgical treatment for ovarian lesions may not benefit from this study.

Why it matters

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

How similar studies have performed: Other studies utilizing liquid biopsy and ctDNA methylation for cancer detection have shown promising results, indicating potential for success in this approach.
