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

120 consecutive patients with "Triple Negative" breast cancers operatable from the outset will be included in the study * To assess the prognostic value of the texture parameters of PET-TDM FDG on event-free survival at 2 years. * To assess the prognostic value of standard parameters (clinical, standard histology, conventional imaging), semi-quantitative PET-TDM FDG and innovative Immuno-histochemistry parameters for 2-year event-free survival . * To assess correlations between continuous PET-TDM FDG texture parameters and Immuno-histochemistry. * To assess the multivariate prognostic value of standard parameters, PET-TDM FDG imaging parameters and Immuno-histochemistry defined as relevant to 2-year event-free survival . * Construction of an optimal prognostic nomogram combining independent parameters to isolate different prognostic subgroups.
