About this study

This phase II trial tests how well dose-reduced docetaxel combined with cyclophosphamide works in treating older women with early stage (stage I-III) HER2 negative breast cancer vulnerable to toxicity. Chemotherapy drugs, such as docetaxel and cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Docetaxel and cyclophosphamide are commonly used, but is not well tolerated at the standard dose and can affect the way older patients feel physically and emotionally. Giving dose-reduced docetaxel combined with cyclophosphamide may be an effective treatment option and improve quality of life in vulnerable older women with stage I-III HER2 negative breast cancer.
