 Hormonal therapy has become the treatment of choice in postmenopausal women with hormone sensitive breast cancer. Even though the treatment of advanced breast cancer in postmenopausal women has improved with the introduction of agents such as aromatase inhibitors, these agents still have limitations, and disease management continues to be sub-optimal. The use of systemic therapies such as hormonal therapy, chemotherapy or new biological treatment is to reduce tumour masses, improve survival and preserve quality of life. Whatever the initial efficacy of the treatment undertaken in metastatic setting, almost every patient will relapse. The main goal is to improve progression free survival PFS. To achieve this, the type of chemotherapy, the optimal duration of chemotherapy, the benefit of maintenance chemotherapy, the benefit of maintenance hormonal treatment are debatable.
