Abstract:

With the improvement of comprehensive treatment of breast cancer and the continuous development of anti-tumor drugs, the survival time of breast cancer patients, especially advanced breast cancer, has been further extended. In recent years, the treatment of advanced breast cancer has ushered an era of fine classification and precise tiered therapy. In 2022, many breakthroughs have been made in the field of advanced breast cancer research. With changes in the treatment of each subtype, some treatment schemes affecting clinical practice have been incorporated into treatment guidelines. The treatment for hormone-receptor-positive advanced breast cancer focuses on patients who have failed treatment with cyclin-dependent kinase 4 and 6 (CDK4/6) inhibitors. Novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugates (ADC) in advanced HER2 positive breast cancer are the focus of research. More research evidence is needed for immunotherapy in advanced triple-negative breast cancer (TNBC), and the treatment with ADC targeting Trop-2 has been effective. Treatment with ADC in HER2-low breast cancer are changing clinical practice. In this article, we summarized the research progress of different types of advanced breast cancer in this year, in order to better guide the individualized treatment and improve the prognosis of advanced breast cancer patients.
