Tissue expression of mismatch repair proteins and tumor lymphocytic infiltration: prognostic significance in resected colorectal carcinoma

Abstract

No relation was found between MMRPE and TLI, with very similar rates of TLI (+) between cases with and without MMRPE. The LTI (+) showed a favourable prognostic effect higher than that of the MMRPE (+). The combination of LTI (+) and MMRPE (+) seems to have an accumulative protective effect, although its limited frequency reduces the significance of the finding.
