Assessment

Primary outcomes

Percentage of post-NAC pathological complete response (pCR rate) according to ZAG expression in pre-NAC primary lesions

Key secondary outcomes

Correlation of ZAG expression and Androgen receptor (AR) in pre-NAC primary lesions
Correlation between ZAG expression and various immune markers (TIL, PDL-1) in pre-NAC primary lesions
Relationship between ZAG expression in the pre-NAC primary lesion and various clinical pathological findings including prognosis
Changes in ZAG, AR, Tumor Infiltrating Lymphocytes (TIL), and PDL-1 in breast cancer tissue before and after NAC
Differences in the clinical pathological significance of ZAG with and without expression of prolactin inducible protein (PIP)
