Colorectal cancer (CRC) is the third most common cancer worldwide and is associated with a high level of mortality and morbidity. In this study we evaluate expression of p-p38 and p-MSK1 in CRC and determine whether there is an association between expression of these markers and any clinicopathologic parameters that could be of prognostic value.

Expression of p-p38, p-MSK1 and ki-67 were examined by immunohistochemistry in 135 archival CRC cases and the findings were correlated with the patient clinicopathological data.

P-p38 and p-MSK1 were expressed at high level in 58.5 % and 60.7% of CRC cases respectively. A statistically significant negative correlation was found between expression of p-p38 and Ki-67 (p < 0.001, r = –0.63) and between p-MSK1 and Ki-67 expression (p < 0.001, r = –0.61). The majority of CRC cases expressing high levels of p-p38 also expressed high levels of p-MSK1 and this correlation was highly significant (p < 0.001, r = 0.863). The high expression of p-p38 and p-MSK1 was also significantly associated with low Dukes and TNM stage. The elevated expression of p-38 and p-MSK1 in CRC was associated with a good prognosis and prolonged overall survival (p < 0.001, each).

Our finding showed that activation of the p38-MSK1 axis determines a good outcome in CRC.
