What this trial studies

The IMPRoVE study is a prospective, non-interventional cohort study aimed at identifying prognostic immune markers in patients diagnosed with epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer. It involves the collection of tumor material, ascites, and blood samples from patients undergoing surgery, chemotherapy, and/or immunotherapy. This observational approach allows researchers to monitor immune responses and their correlation with patient outcomes without administering any treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with primary or recurrent epithelial ovarian cancer who are scheduled for surgery, chemotherapy, or immunotherapy.

Not a fit: Patients with other active malignancies, severe infections, or those receiving immune suppressive treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic tools for better treatment decisions in ovarian cancer patients.

How similar studies have performed: Similar studies have shown promise in identifying immune markers in various cancers, suggesting potential for success in this approach.
