Firstly, univariate analyses Wilcoxon-Mann-Whitney tests with p -value correction for FDR control will be performed to evaluate the relationship between the concentration of each protein and the occurrence of relapse.

Then, a multivariate logistic regression model with elastic-net regularization will be constructed to allow an intrinsic selection of predictive variables proteins.

If necessary, a selection stabilization algorithm will also be applied. The results of the analysis will therefore be the set of predictive variables selected by the selected model, their regression coefficients, as well as an estimation of the model performance with associated confidence intervals.

However, in the absence of a test dataset the performance of the model can only be estimated by cross-validation. To identify a plasma protein profile that is predictive of metastatic relapse, the same approach as for the main objective will be used. Mixed models will be used to account for repeated data. The relationship between, on the one hand, the variation in protein concentration, the variation in TILs, or the variation in PLR and NLR levels, between diagnosis and end of NAC, and, on the other hand, the histological response to NAC, will be studied as in the previous point.

These aspects are also concerned by an intermediate analysis on the first 30 patients. The classical indices for the evaluation of a classification sensitivity, specificity, and precision, among others will be calculated.

Participant recruitment began on 9 th November and is expected to finish in November Study data and finding will be published in peer-reviewed medical journals. We plan to present the study and all data at national congresses and conferences. The discovery of new inexpensive and reliable biomarkers to predict treatment response and metastatic recurrence in TNBC patients remain an important medical need.

Such biomarkers would allow oncologists to offer an alternative treatment to TNBC patients with a high risk of metastatic recurrence. During the last years, many proteins appeared to predict clinical behaviour and new biomarkers have been proposed to predict survival and response to chemotherapy in many cases. Thus, this study would allow us to determine whether a group of plasma proteins can predict response to neo-adjuvant chemotherapy and metastatic relapse in TNBC. Proteins are easily quantifiable and accessible biomarkers that could be used routinely.

Moreover, as many studies have demonstrated, the strength of a liquid biopsy is based on the association of several biomarkers Thus, in the long term, this study and the discovery of various biomarkers such as plasma proteins, ctDNA, and blood cells would help clinicians choosing the best adapted treatment to each patient. More interestingly, the association of these biomarkers could provide a more reliable and powerful composite biomarker in TNBC.
