Breast cancer is the most common malignancy among women worldwide, with approximately 5% to 10% of patients carrying BRCA gene mutations. These patients often present with more advanced disease, face a higher risk of recurrence, and have poorer prognoses. For patients with germline BRCA-mutated (gBRCA) triple-negative breast cancer (TNBC), platinum-based chemotherapy remains the standard treatment but offers limited survival benefits and comes with significant side effects. Meanwhile, for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer patients, endocrine therapy combined with CDK4/6 inhibitors is the first-line standard treatment. However, the optimal therapy after progression on CDK4/6 inhibitors is still unclear. In this era of precision medicine, there is a pressing need for more effective treatments for gBRCA-mutated HER2-negative breast cancer. At the 2024 Cross-Strait Breast Cancer Forum and the Annual Academic Conference of the Fujian Medical Association Breast Disease Branch, Oncology Frontier invited Dr. Huiping Li from Peking University Cancer Hospital to discuss the latest progress in precision treatment for BRCA-mutated breast cancer.
