Assessing regression of cervical precancerous lesions and risk factors

Regression of Cervical Precancerous Lesions and Associated Risk Factors

Observational General University Hospital, Prague · NCT06147388

This study is testing how well certain treatments help women with severe cervical precancerous lesions get better and if there are specific factors that can predict their recovery.

What this trial studies

This observational study aims to evaluate the histopathological regression of severe cervical precancerous lesions (CIN 2 and CIN 3) and the normalization of HPV tests and cytology findings in patients treated conservatively or through conization. Patients will undergo colposcopic evaluations every four months, with biopsies performed to assess regression or persistence of lesions. The study will also identify predictive factors associated with regression and propose a model to predict the likelihood of lesion regression based on the collected data.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 to 40 years with bioptically verified CIN 2 or CIN 3 lesions.

Not a fit: Patients with a history of cervical cancer, invasive lesions, or those who are immunosuppressed may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients who may avoid unnecessary surgical interventions for cervical precancerous lesions.

How similar studies have performed: Previous studies have indicated that a significant proportion of CIN 2 and CIN 3 lesions can spontaneously regress, suggesting that this approach may be promising.
