Ovarian-sparing radiation for young women with pelvic cancers

Ovarian-Sparing Adaptive Radiotherapy in Young Adult Women (OvAR-Y): an In-Silico Feasibility Trial

Washington University School of Medicine · NCT06904365

This study is testing new radiation techniques to see if they can help young women with pelvic cancers keep their ovaries healthy while still getting the treatment they need.

What this trial studies

This observational study focuses on young adult women under 50 years old who are diagnosed with pelvic malignancies such as uterine and rectal cancers. It aims to explore innovative techniques for ovarian-sparing adaptive radiotherapy to minimize the risk of premature ovarian failure, which can lead to significant health issues. The study will utilize advanced imaging techniques like HyperSight cone beam computed tomography (CBCT) and ETHOS 2.0 to assess the effectiveness of these approaches. Participants will be premenopausal women who are planning to receive radiation therapy and meet specific eligibility criteria.

Who should consider this trial

Good fit: Ideal candidates are biologically female patients aged 18 to 50 who are clinically premenopausal and planning to receive radiation therapy.

Not a fit: Patients who have previously undergone pelvic radiation or have a history of ovarian insufficiency or menopause may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help preserve ovarian function in young women undergoing radiation therapy, reducing the risk of associated health complications.

How similar studies have performed: While there is ongoing research in ovarian-sparing techniques, this specific approach appears to be novel and untested in this context.
