Bringing of PET-TDM FDG in the Determination of the Characteristics of Primary Mammary Tumors TrIple Negatives

"Triple Negative" breast cancers are a heterogeneous group characterized by the absence of hormone receptors to estrogen, progesterone and the absence of expression or amplification of the HER-2 gene. This type of cancer is associated with an adverse clinical profile with a high risk of early metastatic relapse. Accurate identification of prognostic factors, as well as predictors of therapeutic response, and the contribution of targeted therapies are avenues for improving the management and survival of patients with these cancers. Such an approach requires optimal biological characterization, allowing us to understand the complexity of this group of tumors, and requires multidisciplinary collaboration in clinical trials involving anatomopathology, oncology and morpho-functional imaging. The investigator's goal is to characterize by innovative methods (anatomo-pathological in particular Of Immunohistochemistry, and morpho-functional imaging (TEP-TDM FDG) semi-quantitative and texture) in a population of Triple Negative Breast Cancer scans better knowledge of this entity that can lead to the development of relevant therapeutic strategies and especially more adapted in the context of precision and personalized medicine.
