Overview
Brief Summary
This study aims to conduct a randomized controlled clinical trial to compare the efficacy and safety of dalpicilib combined with endocrine therapy versus standard endocrine therapy in ER-positive, HER2-negative, lymph node-negative patients with risk factors, in order to further optimize the regimen for adjuvant endocrine therapy in breast cancer.

- •No prior neoadjuvant treatment
- •Time from surgery or completion of chemotherapy or radiotherapy (whichever occurs later) to randomization does not exceed 8 weeks
- •Good postoperative recovery, at least 1 week after surgery

Exclusion Criteria
- •Bilateral breast cancer or ductal/lobular carcinoma in situ (DCIS/LCIS)
- •Received treatment for advanced disease
- •Metastasis at any site

- •Clinically or radiologically suspected malignancy in the contralateral breast not confirmed and requiring biopsy
- •Received neoadjuvant therapy, including chemotherapy, radiotherapy, and endocrine therapy
- •History of malignant tumors within the past 5 years (excluding basal cell carcinoma of the skin and cervical carcinoma in situ), including contralateral breast cancer
- •Patient has been enrolled in other clinical trials
- •Patient has severe systemic diseases and/or uncontrolled infections that prevent participation in the study
