Observational Hubei Cancer Hospital · NCT06050109

This study is testing if continuing ovarian function suppression for premenopausal women with early hormone receptor positive breast cancer after 5 years helps them stay healthier compared to those who stop the treatment.

What this trial studies

This observational study aims to assess the clinical efficacy and safety of continuing ovarian function suppression (OFS) in premenopausal women diagnosed with early hormone receptor positive, HER2 negative breast cancer after they have completed 5 years of OFS treatment. The study will involve two cohorts: one that continues OFS and another that discontinues it, with data collected from hospital medical records over a three-year period. By comparing outcomes between these groups, the study seeks to provide insights into the long-term benefits of sustained OFS therapy.

Who should consider this trial

Good fit: Ideal candidates are premenopausal women aged 18-60 with early hormone receptor positive, HER2 negative breast cancer who have completed 5 years of OFS treatment.

Not a fit: Patients who have not received OFS treatment for at least 5 years or those with significant metastases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable information on the advantages of prolonged ovarian function suppression in improving outcomes for breast cancer patients.

How similar studies have performed: While the approach of evaluating prolonged OFS is not widely tested, similar studies have shown promising results in hormone receptor positive breast cancer management.
