Abstract
BACKGROUND: Breast cancer is one of the most common type of cancers worldwide and remains a critical health issue. Although there are numerous treatment options for advanced metastatic breast cancer, the results are not satisfactory, particularly for triple-negative breast cancer. New treatment modalities need to be explored. CASE PRESENTATION: We present the case of a breast cancer patient with multiple metastases who achieved a good response and tolerance to the combination treatment of utidelone plus capecitabine. After being treated with 10 cycles of combined treatment, the patient is now in a good general condition with a progression-free survival time of 10 months. CONCLUSION: To our knowledge, this is the first report of utidelone plus capecitabine successfully treating a patient with heavily pretreated metastatic breast cancer. This combined treatment offers a new option for patients with multi-drug resistant breast cancer.
