Research on biomarkers in ovarian cancer patients

Biomarker Discovery Project in High Grade Serous Ovarian Cancer

Not applicable Interventional University Health Network, Toronto · NCT03419689

This study is collecting blood and tissue samples from women with advanced ovarian cancer to see if certain markers can help doctors understand the disease better and make more informed treatment choices.

What this trial studies

This study collects biological samples, including blood, tumor tissue, and other fluids, from patients diagnosed with advanced gynecological cancers, specifically high grade serous ovarian, tubal, or primary peritoneal cancer. The samples will be analyzed for biomarkers that may help in understanding the disease and guiding treatment decisions. Participants will receive the results of the testing, which can be shared with their treating physicians to inform their care. The study aims to enhance the understanding of ovarian cancer and improve patient outcomes through biomarker research.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a histological diagnosis of stage III or IV high grade serous ovarian, tubal, or primary peritoneal cancer.

Not a fit: Patients with early-stage (I and II) high grade serous cancers or those with other tumor histologies will not benefit from this study.

Why it matters

Potential benefit: If successful, this research could lead to more personalized and effective treatment options for patients with advanced ovarian cancer.

How similar studies have performed: While this approach to biomarker research is common, the specific focus on advanced gynecological cancers may provide novel insights that have not been extensively tested.
