In this study participants will be treated with capecitabine. Capecitabine will be administered orally at a dose of 500 mg 3 times daily for up to 12 months, or until the time of clinical recurrence, discontinuation due to toxicity, or withdrawal of consent. This study will have two stages, stage 1 would enroll up to 8 participants to clear the Minimal Residual Disease (MRD) and Stage 2 will enroll up to 5 participants. The purpose of this study is to determine if this study population would have a better outcome from receiving capecitabine rather than having no change in treatment if MRD is detected.",[67,68,69,70],"ER-positive, HER2-negative Breast Cancer","Breast Cancer Stage I","Breast Cancer Stage II","Breast Cancer Stage III","2026-06-09",{"date":73,"type":74},"2026-06-11","ACTUAL",{"date":76,"type":61},"2026-06-30",{"date":78,"type":61},"2029-08-01",{"name":5,"class":6},1]
