SYSUCC-001Phase III Study of Adjuvant Capecitabine Metronomic Chemotherapy in Triple-negative Operable Breast Cancer

Triple negative breast cancer (TNBC) is an aggressive disease without tumor-specific treatment options. Patients with triple-negative disease had an increased likelihood of distant recurrence and death within 5 years of diagnosis. Median time to distant recurrence was significantly shorter. This study will evaluate the efficacy and safety of the addition of Capecitabine to standard adjuvant therapy in patients with triple negative breast cancer. Patients will be randomized to receive either standard chemotherapy (according to NCCN guideline), or standard chemotherapy followed by 1 year of metronomic Capecitabine (650mg/m2, twice every day). The anticipated time on study treatment is 12 months, and the target sample size is 432 individuals.Disease-free Survival (DFS) will be primary end point.
