|Metastatic Breast Cancer||Biological: Determination of ESR1 mutations||Not Applicable|
Breast cancer is the most common cancer in woman. Aromatase inhibitors have demonstrated a real efficacy however a resistance to treatment exists.
ESR1 mutations appear like involved in the mechanism of resistance to aromatase inhibitors treatment.
The purpose of the study is to determine the frequency ESR1 mutations by Digital PCR in patient with metastatic breast cancer.
The significance of the Digital PCR technique will be determined first in plasma issued from healthy volunteers.
At the initiation of aromatase inhibitors treatment patient with metastatic breast cancer will be included in the study. During their follow-up visit every 3 months), their status towards their disease will be collected and a plasma will be collected too.
When the patient progress clinically or radiologically the plasma concomitant to this progression will be analysed by Digital PCR to detect ESR1 mutations.
The patient will be followed during 2 years.

Experimental: Determination of ESR1 mutations
Blood sample will be collected every 3 months during two years to determine ESR1 mutations
Biological: Determination of ESR1 mutations
Blood sample prelevement. Plasma issued from patient with metastatic breast cancer will be analysed at progression by Digital PCR to detect ESR1 mutations
- Frequency of ESR1 mutations [ Time Frame: up to 24 months ]Determination of the frequency of ESR1 mutation in patient who have a clinical and/or a radiological progression disease
- Frequency of progression without ESR1 mutations [ Time Frame: up to 24 months ]Determination of frequency of patient with a progression disease and without any ESR1 mutations
- Time between introduction of aromatase inhibitor and detection of ESR1 mutations [ Time Frame: up to 24 months ]Time between introduction of aromatase inhibitor and detection of ESR1 mutations by digital PCR
