Study to Assess Prevalence of the Folate Receptor Alpha (FRa) in Adult Female Participants With Ovarian Cancer in Intercontinental (InterCon) Countries

Epithelial ovarian cancer (OC), including fallopian tube and primary peritoneal cancer, is the deadliest gynecologic malignant neoplasm with a 5-year relative survival of approximately 50%. This study will evaluate the concordance in folate receptor alpha (FRa) immunohistochemistry (IHC) in adult female participants with ovarian cancer. Archived tissue biopsies will be tested for FRa and data from approximately 1,000 participants will be collected. This is a retrospective study and testing will be performed prospectively on archived samples. Participants' charts will be reviewed. No drug will be administered as a part of this study. The duration of the study will be approximately 1 Year. There is no additional burden for participants in this trial.
