Colorectal cancers are the third most common in both sexes and they are the
second most common cause of cancer-related death. 12-15% of colorectal cancers
develop through microsatellite instability (the hereditary mutation in at least
one of DNA mismatch repair genes) pathway and they are 2-5% hereditary. In this
study, we investigated the correlation between the clinicopathological features
themselves and also the correlation between them and the immunohistochemical
MLH-1, MSH-2, PMS-2, MSH-6 expressions in a total of 186 resection materials with
colorectal adenocarcinoma between 2008 and 2012. All the cases were
retrospectively evaluated in terms of age, sex, localization, size, accompanying
polyp, multiple tumor, arising from polyp, differentiation, mucinous
differentiation, pathological tumor stage, lymphovascular and perineural
invasion, lymphocyte amount in the tumor microenvironment, surgical border and
lymph node metastasis. We prepared multiple tissue blocks which had 4-millimeter
tumor. Immunohistochemically, MLH-1, MSH-2, PMS-2, MSH-6 primary antibodies were
studied. Statistically, "Kruskal-Wallis" ve "Pearson's chi-squared" tests were
used. We found a positive correlation between loss of MLH-1 and PMS-2 expressions
and the right-colon location, poor and mucinous differentiation and dense
lymphocytic infiltration. In addition, loss of MSH-2 and MSH-6 expressions was
correlated with the right-colon location, poor and mucinous differentiation. We
found a meaningful relationship between immunohistochemical markers and
clinicopathological features usually observed in tumors with microsatellite
instability. This finding may arouse suspicion for MSI. However, the findings in
our study must be supported with studies conducted in large series including
molecular methods.
