| Main Objective: To determine the percentage of progression free survival after a 6-month monotherapy of Estramustine in patients with HER2-/RH+ breast cancer progressing after having already undergone either a first line adjuvant treatment by aromatase inhibitors (AI);Secondary Objective: - To describe the risks of thrombosis by the analysis of the following biomarkers : D-Dimer, prothrombin fragment 1+2, von Willebrand factor, fibrinogen, Chain Reaction Protein (CRP) - To describe the clinical benefit of estramustine every 2 months during the one-year patient follow-up (RECIST criteria) - To describe the correlation between the answer rate and the decrease of the following biomarkers: LDH, ACE and CA 15-3 every 2 months during the one-year patient follow-up - To evaluate tolerance of estramustine and tamoxifene treatments every 2 months during the one-year patient follow-up - To analyse the proportion of patients developing thromboembolic events in the 2 groups every month every during the one-year patient follow-up - To evaluate patient's quality of life (questionnaire EORTC QLQ-C30 and EORTC QLQ-BR23) every 4 months every during the one-year patient follow-up ;Primary end point(s): Proportion of patients in progression-free survival (PFS) after a 6-month treatment is the main judgement criterion. The PFS is defined as the duration of objective response or stabilisation of the disease according to the Recist criteria. The following events shall be considered as progressive : - Relapse - Treatment intolerance leading to stop the treatment - Death | — |
