However, based on the results, we do not consider E‐cadherin to be an independent predictor, but rather a surrogate marker of the SGST subtype: this is illustrated by the fact that all the SGST in the poor response subgroup (8/10) showed no expression of E‐cadherin (H‐score 0) while two remaining non‐SGST tumours showed E‐cadherin expression comparable to the subgroup with good response (H‐scores 104 and 155). This evidence concerns the gene CDH1 and neoplasm.
