HER2-Positive Metastatic Breast Cancer Overview

HER2-positive metastatic breast cancer is a highly aggressive molecular subtype driven by amplification of the ERBB2 gene, resulting in overexpression of the human epidermal growth factor receptor 2 (HER2), a transmembrane tyrosine kinase. Historically associated with rapid disease progression, high visceral involvement, and a strong propensity for central nervous system (CNS) metastases, the disease course has been significantly transformed by targeted therapies.

Accurate determination of HER2 status via immunohistochemistry (IHC) or in situ hybridization (ISH) is essential for guiding treatment. The modern therapeutic paradigm is based on sequential HER2-targeted therapy, beginning with dual monoclonal antibody blockade using trastuzumab and pertuzumab in combination with chemotherapy.

Upon progression, treatment has evolved with the introduction of next-generation antibody-drug conjugates (ADCs), particularly trastuzumab deruxtecan (T-DXd), which has demonstrated superior efficacy and largely replaced earlier agents such as T-DM1. In later lines, especially for patients with brain metastases, CNS-penetrant tyrosine kinase inhibitors (e.g., tucatinib) play a critical role in achieving both systemic and intracranial disease control.
