Résumé
Triple-negative breast cancer (TNBC) is the most heterogeneous breast cancer subtype, posing numerous challenges in clinical decision-making. Biomarkers are essential to personalize management of TNBC patients. While tumor infiltrating lymphocytes (TILs) are validated prognostic biomarkers, the requirement for tumor biopsy limits their routine use. Therefore, more accessible and reliable quantitative biomarkers are needed. Given the significant role of systemic inflammatory response in tumor onset and progression, assessing inflammatory cells via liquid biopsies emerges as a promising alternative. The PERCEPTION study, conducted at Centre Jean Perrin in France, aims to determine the correlation between TILs and peripheral blood components at diagnosis. An interim analysis was conducted after enrolling 50% of the estimated population, to evaluate study feasibility and preliminary correlations between blood cell counts and TILs. Sixty-one patients were enrolled over 4.5 years, demonstrating a good inclusion rate with minimal missing data. Preliminary results for 36 analyzable patients showed no correlation between the neutrophil-to-lymphocyte ratio (NLR) and TILs (r The interim analysis of the PERCEPTION study confirms the feasibility of correlating blood cell counts with TILs in TNBC. Although no significant correlation was observed between NLR and TILs, the moderate positive correlation between the CD8/FoxP3 ratio and TILs suggests a potential link between systemic inflammation and local immune response. These findings underscore the potential of blood-based markers as non-invasive surrogates for TILs, encouraging further research to enhance prognosis and guide treatment strategies in TNBC.

BACKGROUND/AIM
OBJECTIVE
Triple-negative breast cancer (TNBC) is the most heterogeneous breast cancer subtype, posing numerous challenges in clinical decision-making. Biomarkers are essential to personalize management of TNBC patients. While tumor infiltrating lymphocytes (TILs) are validated prognostic biomarkers, the requirement for tumor biopsy limits their routine use. Therefore, more accessible and reliable quantitative biomarkers are needed. Given the significant role of systemic inflammatory response in tumor onset and progression, assessing inflammatory cells via liquid biopsies emerges as a promising alternative.

METHODS
The PERCEPTION study, conducted at Centre Jean Perrin in France, aims to determine the correlation between TILs and peripheral blood components at diagnosis. An interim analysis was conducted after enrolling 50% of the estimated population, to evaluate study feasibility and preliminary correlations between blood cell counts and TILs.

CONCLUSION
CONCLUSIONS
The interim analysis of the PERCEPTION study confirms the feasibility of correlating blood cell counts with TILs in TNBC. Although no significant correlation was observed between NLR and TILs, the moderate positive correlation between the CD8/FoxP3 ratio and TILs suggests a potential link between systemic inflammation and local immune response. These findings underscore the potential of blood-based markers as non-invasive surrogates for TILs, encouraging further research to enhance prognosis and guide treatment strategies in TNBC.
