Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with newly diagnosed epithelial ovarian cancer who are eligible for platinum-based chemotherapy.

Probably not a fit

Patients with non-epithelial ovarian tumors, recurrent disease, or those who have already undergone curative treatment will not benefit from this study.

What this trial studies

This prospective study aims to identify factors contributing to resistance against platinum-based chemotherapy in patients diagnosed with epithelial ovarian cancer at any stage. Participants will receive standard platinum-based chemotherapy while clinical, biological, epidemiological, and therapeutic data will be collected over a five-year period. Biological samples, including blood, tumor biopsies, and ascites, will be collected concurrently with standard care procedures, ensuring no additional invasive procedures are required. The study will help build a comprehensive database to better understand treatment resistance.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for patients with platinum-resistant ovarian cancer.

How similar studies have gone: While studies on chemotherapy resistance exist, this specific approach focusing on platinum resistance in ovarian cancer is novel and may provide new insights.
