[Medical treatments of endocrine-sensitive Her-2 negative breast cancers: a review].

New molecular classification is one of the cornerstones of current and future progress in research and patient care for breast carcinoma. For the larger hormone-receptor positive and Her-2 negative subgroup, which concerns 75% of the patients, endocrine therapy and chemotherapy may be considered. Looking toward new-targeted therapies, this paper reviews the current use of these two treatment modalities in adjuvant, neoadjuvant and metastatic settings of this disease.
