Table 2.

Expression of markers in the tumor center and invasion front detected by immunohistochemistry, stage UICC II: lymph node negative colon carcinomas, stage UICC III: lymph node positive colon carcinomas, values are presented as percent positive tumor cells. The p value is calculated by the two-sample Wilcoxon test. Significant proteins are shown in bold.
