- Conditions
- Breast Cancer
- Interventions
- Registration Number
- NCT02914158
- Lead Sponsor
- First Affiliated Hospital, Sun Yat-Sen University
- Brief Summary
The objective of this study is to compare the curative effects in patients under the age of 35 with hormone receptor positive breast cancer and high recurrent risk factors including large tumor or metastatic lymph nodes randomized to ovarian function suppression (OFS) plus aromatase inhibitors or OFS plus tamoxifen as adjuvant endocrine therapy, and explore the differences of curative effects between different subtypes to provide direct evidence for treatments of young breast cancer patients.

- Primary Outcome Measures
Name Time Method Disease-Free Survival (DFS) 5 years DFS is defined as the time between randomization and the date of the first occurrence of events as follow: local, regional recurrence or distant metastasis of invasive breast cancer, contralateral invasive breast cancer, or death due to any diseases. Patients who have not had disease progression or death at the end of follow-up (5 years) will be censored at the date last known to be alive and distant metastasis free. Subgroup analysis DFS of Luminal A and Luminal B breast cancer.
- Secondary Outcome Measures
Name Time Method Overall Survival (OS) 5 years The time from randomization to death due to any cause. Patients still alive at the end of follow-up (5 years) will be censored at the last known alive date.
Invasive Breast Cancer Recurrence-Free Interval（BCFI) 5 years The time between randomization and the first occurrence of local, regional recurrence or distant metastasis of invasive breast cancer, or contralateral invasive breast cancer. Patients who have not had invasive breast cancer recurrence at the end of follow-up (5 years) will be censored at the date last known to be distant metastasis free.
