Evaluating a new system to assess fertility risks in young cancer survivors

Evaluating a New Gonadotoxic Risk Stratification System

University of Colorado, Denver · NCT05052632

This study is testing a new system to see how well it can predict fertility risks in young women who have survived cancer treatments.

What this trial studies

This observational study aims to evaluate a newly developed gonadotoxic risk stratification system and its correlation with post-treatment ovarian reserve, measured by FSH and AMH levels. The study will analyze the agreement between these two variables over the first two years following treatment, using statistical methods such as kappa statistics and ordinal logistic regression. Participants will include female patients aged 8 to 39 who are at risk for fertility issues due to cancer treatments. The study will also consider various participant characteristics, including age, race, ethnicity, and BMI, to ensure accurate results.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 8 to 39 who have completed cancer treatment and are at risk for fertility problems.

Not a fit: Patients with disorders of sexual development or those who have undergone bilateral oophorectomy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a better understanding of fertility risks in young cancer survivors, leading to improved fertility preservation strategies.

How similar studies have performed: While similar studies have explored fertility risks in cancer survivors, this specific approach using a new risk stratification system is novel.
