Although data is limited, neoadjuvant endocrine therapy appears to as effective as chemotherapy in converting mastectomy to lumpectomy. In addition, neoadjuvant endocrine therapy allows an early assessement of tumor responsiveness to endocrine therapy so that adjuvant treatments could be tailored accordingly.
