Is this trial a fit for you?

Likely a good fit

Ideal candidates include women over 50, those with a family history of ovarian cancer, or those with a personal history of breast cancer.

Probably not a fit

Patients with known pelvic masses, prior ovarian cancer, or those who cannot safely undergo transvaginal ultrasound will not benefit from this study.

What this trial studies

This study evaluates the effectiveness of serial transvaginal ultrasonography as a screening method for ovarian cancer in women at intermediate to high risk. Participants from various counties in Kentucky will undergo regular screenings based on a published algorithm to monitor for ovarian malignancies. The study aims to reduce false-positive rates and improve the positive predictive value of the screening without missing true positive cases. The long-term survival rates of women with screen-detected ovarian cancers will also be assessed.

Why it matters

Potential benefit: If successful, this approach could significantly improve early detection rates of ovarian cancer, leading to better survival outcomes for patients.

How similar studies have gone: Previous studies have indicated that screening can improve survival rates for ovarian cancer, suggesting that this approach may be effective.
