When multivariate analysis was corrected by the covariables tumor size, histological grade, lymph nodes, hormone receptors, ErbB2, therapy (adjuvant chemotherapy and hormones), the best predictive markers for the presence of BrM were FN14 (p < 0.0001) followed by GRP94 (p = 0.0017). Here, HSP90B1 is linked to neoplasm.
