Determining Prognostic Immune Markers in Patients With Ovarian Cancer

Recruiting
Conditions
Epithelial Ovarian Cancer
Interventions
Other: No intervention
Registration Number
NCT03862677
Lead Sponsor
Leiden University Medical Center
Brief Summary

The IMPRoVE study is a prospective, non-interventional, explorative cohort study to determine prognostic immune markers in patients with epithelial ovarian cancer, fallopian tube cancer, and primary peritoneal cancer (EOC).

Detailed Description

Tumor material, ascites (if possible) and blood samples for immune monitoring will be collected from patients with primary and recurrent EOC undergoing surgery, chemotherapy and/or immunotherapy.

Inclusion Criteria
  • Patients with (suspicion of) primary or recurrent EOC with an indication for surgery, chemotherapy and/or immunotherapy.
