Magnetic resonance imaging (MRI) is the method of choice in breast cancer to perform the loco-regional staging and direct the treatment.
European Guidelines (EUSOMA) currently recommend MRI for initial evaluation and assessement of the neoadjuvant chemotherapy (NAC) response, for breast cancer. The standard of care consists of realizing a MRI before the start of the NAC and another one after it's ended, six months later.
There is currently no consensus on the realization of an interval MRI for early assessment of the chemosensitivity of the tumor. It would allow though alterations in the therapeutic regimen in the event of a non response. Similarly, there is no consensus on when this interval MRI should be performed.
Some recent studies suggest that Diffusion-weighted Magnetic Resonance Imaging is interesting for the evaluation of the early response. However, these are preliminary studies with quantitative measures realized by the region of interest (ROI) method. A response to neoadjuvant chemotherapy results in elevated values of apparent diffusion coefficients (ADC).
The investigator's goal for this study is to evaluate the reliability of diffusion as tumor biomarker. Therefore, they will study the quantitative analysis of the diffusion-weighted magnetic resonance sequences in the pre-therapeutic assessment and the early and late follow-up of breast cancers under neoadjuvant treatment (chemotherapy, hormonotherapy...) within the CHU Brugmann hospital. The results of this analysis will be compared with the MRI results obtained at the end of the treatment and with the histology of the initial biopsy and the surgical specimen.
The expected benefits are:

| Diffusion-weighted Nuclear Magnetic Resonance Imaging (MRI) | Device | MRI examinations performed on two devices: Ingernia 3 Testla (Philips) on the Horta site of the CHU Brugmann hospital, and Area 1,5 Tesla (Siemens) on the Brien site of the CHU Brugmann hospital. Diffusion sequences last 6 minutes and are already performed in the standard of care. Compared to the standard of care, one additional MRI will be performed one month after the start of the neo-adjuvant treatment, with diffusion analysis.The post-processing of the examinations will be realized with the Syngo Onco Care application of Siemens. |

| Anatomo-pathology classification - histological type | The histological type of the tumor will be determined by the Anatomo-Pathology Department of the CHU Brugmann hospital, according to standard of care. The determination will be performed on the initial biopsy samples used for diagnosis and/or on the surgical specimen. | Baseline: start of the neo-adjuvant therapy |
