Anti‐tumour effects were assessed by measuring pathologic complete response (pCR), survival analysis, immunohistochemistry for E‐cadherin, VEGF, MMP9, MMP2 and Ki‐67, serum measurement of IFNγ and IL‐4, and gene expression analysis of CD105, VEGFa, VEGFR2 and COX2. This evidence concerns the gene ENG and neoplasm.
