Breast cancer biomarkers after neoadjuvant therapy.

Chemotherapy is one of the basic therapeutic procedures of breast cancer (BC) which may precede and/or follow the surgical resection of a tumor as a part of neoadjuvant or adjuvant therapy. However, the selective pressure of chemotherapy on tumor cells may change their molecular and expression profile and thus also their chemosensitivity. The aim of our work was to document the expression changes of selected markers in BC after neoadjuvant chemotherapy, which may contribute to the understanding of the role of these proteins and genes in tumor response to chemotherapy and the development of chemoresistance. Immunohistochemical analysis of expression of standard BC markers [estrogen (ER) and progesterone receptors (PR), HER2 and proliferation activity (Ki67)] and intercellular junction proteins (claudin 1, 3 and 4, E- and N-cadherin) before and after neoadjuvant chemotherapy revealed a decrease of PR, Ki67 and claudin 3 expression and an increase of claudin 1 expression. The expression of ER, HER2, claudin 4, E- and N-cadherin proved to be stable. Assessment of standard BC markers is performed routinely during a bioptic investigation as a necessary factor for therapy indication. Our results support the current recommendations for the re-examination before indication of adjuvant chemotherapy. Claudins...
