Brief Summary

This study aims to evaluate the efficacy and safety of capecitabine as the only adjuvant chemotherapy drug in patients with low-risk early triple-negative breast cancer who have received adequate local treatment. Patients meeting the inclusion criteria will receive capecitabine metronomic therapy for one year.

Detailed Description

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.
