The results indicated that high Trop2 expression was significantly associated with lower E‐cadherin expression and acquisition of expression of vimentin.25 In our previous study, we also found Trop2+/E‐cadherin−was expressed in breast cancer (BC) and was associated with lymph node status, metastasis, tumor‐node‐metastasis (TNM) stage, and ER−/PR−/HER2− expression. This evidence concerns the gene VIM and breast cancer.
