Brief Summary

Colorectal cancers are the third most common type of cancer in the world. Peritoneal carcinomatosis and intraabdominal acid development occur in advanced stages of colorectal cancers. It is known that the immune system plays an important role in tumor development or tumor eradication. Differentiation of T cells towards Th2 and regulatory T cells is also reported to be effective in tumor progression. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role. The role of regulatory T lymphocytes, a subgroup of T cells that play a regulatory role by suppressing the function of other T lymphocytes, is to reduce the chronic immune response against viruses, tumors and patients's own antigens. The common feature of all Tregs is that they secrete one or more anti-inflammatory molecules such as IL-10, TGFβ or IL-35. High levels of Tregs have been found in peripheral blood, tumor tissue and lymph nodes in patients with malignancy. In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid T helper cytokine levels in patients with end-stage colorectal cancers compared to patients without malignancy.
