Brief Summary:
Therapeutic interventions for patients with metastatic breast cancer are aimed at prolonging survival and improving the quality of life. The objective of this trial is to assess if an initial chemotherapy followed by an endocrine therapy leads to a longer disease-free interval as compared to chemotherapy alone.
