Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To observe and evaluate the clinical efficacy and safety of continuous use of OFS for premenopausal patients with early breast cancer after 5 years use of OFS.

This study is a multicenter, prospective, observational, non randomized controlled, open-label real world study based on hospital medical record system data, aimed at evaluating the benefits of continuing to use OFS after 5 years of use. The retrospective analysis plan includes patient data from September 1, 2023 to September 1, 2026. Join two cohorts: the continued use group and the discontinued use group after 5 years of OFS, respectively.
