Long-term risk assessment of vaginal intraepithelial neoplasia in patients with cervical neoplasia

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals aged 20 years and older with a previous history of CIN.

Probably not a fit

Patients without a history of cervical intraepithelial neoplasia or those under 20 years old may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to construct a longitudinal risk model for vaginal intraepithelial neoplasia (VAIN) based on the distribution of human papillomavirus (HPV) types in patients with a history of cervical intraepithelial neoplasia (CIN2+). It will include three arms to gather follow-up data from a previous cohort while also prospectively recruiting new subjects to enhance the sample size. The study addresses the lack of long-term outcome data for patients with antecedent CIN and aims to better understand the relationship between HPV and VAIN progression.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the risk factors for VAIN, potentially leading to improved screening and management strategies for affected patients.

How similar studies have gone: While there have been limited studies on VAIN, this approach is novel in constructing a longitudinal risk model specifically for this condition.
