A score from 0 to 3 was given for the number of positive cells and from 0 to 3 for the intensity of staining in these cells, in both healthy and metastatic liver parenchyma.RESULTS: No significant differences in the expression of E-cadherin, β- and γ-catenin, VEGF and p53, could be observed between patients who received and did not receive chemotherapy, in both normal and metastatic liver parenchyma.CONCLUSION: Despite the assumption that chemotherapy had an effect on liver metastasis, no influences were noticed immunohistochemically.展开更多
