Notably, suggestive evidence of an association was seen between N-cadherin positive status in the PT and negative ER status (P = 0.03), and triple-negative St Gallen subtype (P = 0.02), as well as between vimentin positive status in the PT and younger age (P = 0.006), and tumor size > 20 mm (P = 0.02). This evidence concerns the gene CDH2 and neoplasm.
