title: [Expression of some biomarkers in primary colon adenocarcinomas and their lymph node metastases].
abstract: The samples of colon adenocarcinomas (CAC) and their lymph node metastases from 22 patients were studied. The expression of thymidylate synthase (TS), vascular endothelial growth factor (VEGF), epidermal growth factor receptor (EGFR), E-cadherin, beta-catenin, tenascin C (TN), and KAI-1/CD82 in primary CAC and their lymph node metastases was compared using an immunohistochemical method. The expression of TS, VEGF, EGFR, E-cadherin, TNC, and KAI-1 was statistically significant different in primary CAC and involved lymph nodes. Comparison of the expression of the markers in the pairs of primary CAC and metastasis revealed equal values for TNC and EFGR in 45.5 and 41% of cases, respectively; the number of coincidences in the expression of the other markers was insignificant. Determination of the expression of molecular biological markers in primary CAC and their lymph nodes may serve as a predictor of therapy response and have a prognostic value.
