Official title
Cohort Study of Chemotherapy Combined With Targeted Adjuvant Therapy for High-risk HER2 Positive and Lymph Node Negative Early Breast Cancer
Overview
Human epidermal growth factor receptor 2 (HER2) positive breast cancer is a molecular subtype with high malignancy and easy recurrence and metastasis. The emergence of HER2 targeted drugs has greatly improved the prognosis and survival of such patients. At present, for HER2 positive breast cancer patients with negative lymph nodes, chemotherapy drugs combined with trastuzumab is the current standard treatment scheme, and in most cases, chemotherapy uses a combination of two drugs, while the main beneficiaries of the target treatment of trastuzumab and pertuzumab are concentrated in the group of patients with positive lymph nodes. Can the use of target therapy to de-escalation chemotherapy and further achieve a strategy of high efficacy and low toxicity. It is planned to explore the efficacy and safety of T1-T2, HER2 positive early breast cancer patients with negative lymph nodes to achieve chemotherapy reduction based on risk stratification.
Primary outcome measures

- distant disease free survival [Time frame: 5 years]
- breast cancer specific survival [Time frame: 5 years]
- overall survival [Time frame: 5 years]
