详细描述
This study aims to evaluate the efficacy and safety of capecitabine as the only adjuvant chemotherapy drug in patients with low-risk T1N0M0 early triple-negative breast cancer who have received adequate local treatment. Patients meeting the inclusion criteria will receive capecitabine metronomic therapy for one year. The low-risk population defined in this study includes the IM subtype with abundant stromal tumor-infiltrating lymphocytes, or the LAR subtype with low ki-67 proliferation, or elderly patients.
