About this study

HR-positive breast cancers accounts for about 50% to 60% of all breast cancer patients. Neoadjuvant Chemotherapy is the core treatment mode for this type of breast cancer, and endocrine therapy can be used in some low-risk patients. However, the pathological complete response (pCR) rate obtained is low. HER2 is an important prognostic indicator and therapeutic target for breast cancer. Nearly 60% of HR-positive breast cancers have low expression of HER2, and antibody-drug conjugates (ADC) targeting HER2 may achieve better efficacy in this subtype.
