Managing high-grade cervical lesions in women planning future pregnancies

Conservative Management of Patients Diagnosed With High-grade Squamous Intraepithelial Lesions (H-SIL) Who Have Pregnancy Intentions: a Prospective Observational Study

Observational Fundació Institut de Recerca de l'Hospital de la Santa Creu i Sant Pau · NCT04783805

This study is testing if women of childbearing age with high-grade cervical lesions can safely manage their condition without immediate surgery and if the lesions might go away on their own over time.

What this trial studies

This observational study aims to evaluate the rates of spontaneous regression of high-grade squamous intraepithelial lesions (HSIL) in women of reproductive age who prefer conservative management instead of immediate surgical treatment. Conducted at a tertiary hospital, the study will follow participants with regular colposcopy, cytology, HPV testing, and biopsies over a period of up to 24 months. The goal is to determine whether conservative management can be safely recommended for women of childbearing potential, regardless of age, while monitoring for any progression of lesions.

Who should consider this trial

Good fit: Ideal candidates are women of reproductive age with aspirations for future pregnancies who accept conservative management.

Not a fit: Patients who are currently pregnant, immunosuppressed, or have a diagnosis of cervical cancer will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a safer alternative to surgery for women with HSIL, preserving their reproductive options.

How similar studies have performed: Previous studies have shown promising results for conservative management of HSIL, particularly in younger women, suggesting that this approach may be viable.
