Background:
Neoadjuvant systemic therapy (NAT) represents an attractive option for improved outcomes of early-stage breast cancer (BC) patients, as it can significantly reduce tumor burden thus permitting breast-conserving resections. Equally important, the eradication of viable cancer cells post-NAT, also known as pathological complete response (pCR), has emerged as a strong prognostic biomarker, reflecting tumor's biology and subsequent treatment responses. Yet to date, no validated markers predictive of pCR have been identified.
Methods:
The present retrospective study aimed to explore the value of neutrophil-tolymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) as potential predictors of pCR.
Results:
Despite no statistically significant associations have been reported, NLR and PLR dynamics during NAT, as longitudinal inflammatory phenotypes, merit further investigation in larger cohorts.
Conclusion:
In the future, the integration of a comprehensive inflammatory biomarker panel into clinical practice could assist in a priori treatment selection process.
