|3D Shear Wave Elastography (SWE)||
Procedure: 3D Shear Wave Elastography (SWE)
Ultrasound imaging with Elastography will be performed at the inclusion (T0), after course 1 and course 2 respectively with anthracyclines, at the end of anthracycline treatment and at the end of taxane treatment.
Optional biopsy of breast tumor under neoadjuvant chemotherapy after the course 2 of anthracycline.
- Assess the accuracy of the sequential measurements by 3D Shear Wave Elastography (SWE) for predicting histological response to neoadjuvant chemotherapy [ Time Frame: up to 32 months ]Measure of the tumor prior to neoadjuvant chemotherapy (T0), at T1 and T2(1stand 2nd courses of anthracycline), at mid-treatment between anthracycline and taxane chemotherapy (Tmi), at the end of chemotherapy before surgery (Tfin).
- Elastic properties before treatment (especially ratio between tumor and glandular breast or fat tissues close to the tumors) [ Time Frame: up to 32 months ]Use technic Supersonic Shear Imaging.
- peritumoral environmental elasticity properties [ Time Frame: up to 32 months ]Use technic Supersonic Shear Imaging (Explorer, Supersonic Imagine).
- Reliable early biomarker of histological response. [ Time Frame: up to 32 months ]Estimate under chemotherapy if early changes in tumor's elasticity can provide a reliable early biomarker of histological response.
- tumor volume changes under treatment by 3D ultrasound [ Time Frame: up to 32 months ]Estimate tumor volume changes under treatment by 3D ultrasound and Compare with measurements obtained by other conventional imaging methods currently used for monitoring patients under neoadjuvant chemotherapy
- Compare changes in tumor elasticity under chemotherapy to variables obtained by other imaging modalities (Breast MRI) performed in clinical routine [ Time Frame: up to 32 months ]
- Compare changes in tumor elasticity under neoadjuvant chemotherapy to changes in diffusion apparent coefficient by using technic Supersonic Shear Imaging (Explorer, Supersonic Imagine). [ Time Frame: up to 32 months ]
- Compare changes in tumor volume to histological response (Gold Standard : surgery after neoadjuvant chemotherapy according to " Residual Cancer Burden " score [ Time Frame: up to 32 months ]
- Compare predictive value (semi-quantitative et quantitative measurements) of tumor elasticity [ Time Frame: up to 32 months ]
- Assess vascular shape and its evolution under treatment by Ultrasensitive Doppler technic "Ultra-Fast Doppler" [ Time Frame: up to 32 months ]
- Compare tumor elasticity to conventional histological parameters [ Time Frame: 6 weeks ]For the additional biopsy (optional) under neoadjuvant chemotherapy at T2, correlation elastography to pathological parameters of peritumoral environment by analyzing conventional histological parameters.
