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.
