A Real-world Study on the Compliance of OFS-assisted Endocrine Therapy for Hormone Receptor-positive(HR+) Premenopausal Breast Cancer
Sponsor: Zhejiang Cancer Hospital
Summary
The goal of this observational study is to observe the long-term prognosis of patients with early HR-positive premenopausal breast cancer. The study also aims to understand the compliance with and reasons for discontinuing adjuvant OFS endocrine therapy under different combination regimens. The main questions it aims to answer are: 1. What are the rates of compliance with and reasons for discontinuation of adjuvant OFS endocrine therapy? 2. What is the impact of OFS treatment duration on patient prognosis? Participants, who are already receiving OFS treatment as part of their regular medical care, will have their demographic data, treatment status, clinical outcomes, and adverse events collected over time.
