The PERCEPTION study aims to assess the correlation between blood cell counts (Leucocytes, Neutrophils, Lymphocytes, Platelets, NLR (Neutrophil-to-Lymphocyte Ratio) and PLR (Platelet-to-Lymphocyte Ratio)) and Tumor Infiltrating Lymphocytes (TILs), at baseline and after surgery, for patients diagnosed with triple negative breast cancer. It also aims to assess these circulating elements and circulating tumor DNA as predictive factor of metastatic recurrence in triple negative breast cancer.

Assessment of the correlation between the lymphocyte infiltration rate assessed on biopsy, and the NLR (neutrophil-to-lymphocyte ratio) measured on blood samples, in women with triple negative breast cancer, at the time of diagnosis.
Timeframe: 3 years (the period of recruitment)
