dc.description.abstract | Triple-negative breast cancer (TNBC) is particularly challenging due to the weak or absent
response to therapeutics and its poor prognosis. The effectiveness of neoadjuvant chemotherapy
(NAC) response is strongly influenced by changes in elements of the tumor microenvironment
(TME). This work aimed to characterize the residual TME composition in 96 TNBC patients using
immunohistochemistry and in situ hybridization techniques and evaluate its prognostic implications
for partial responders vs. non-responders. Compared with non-responders, partial responders
containing higher levels of CD83+ mature dendritic cells, FOXP3+ regulatory T cells, and IL-15
expression but lower CD138+ cell concentration exhibited better OS and RFS. However, along
with tumor diameter and positive nodal status at diagnosis, matrix metalloproteinase-9 (MMP-9)response to NAC. This study yields new insights into the key components of the residual tumor bed,
such as MMP-9, which is strictly associated with the lack of a pathological response to NAC. This
knowledge might help early identification of TNBC patients less likely to respond to NAC and allow
the establishment of new therapeutic targets.
