Immune Checkpoints in Intraabdominal Ascites Fluid
Measurement of Immune Checkpoints in Intraabdominal Ascites Fluid in Patients With Advanced Colorectal Cancer
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. Among the mechanisms of escape from the immune system, changes in the tumor microenvironment play an important role.
Immune checkpoints are molecules that have become popular especially after the Nobel Prize in 2018, and are important in revealing the relationship between cancer and the immune system.
In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid immune checkpoints level in patients with advanced colorectal cancer patients compared to patients without malignancy.

Detailed Description
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. The role of the immune system in colorectal cancers has been demonstrated with the effects of tumor-infiltrating lymphocytes (TIL) and immune control points on TILs or immune control point ligands on patient survival, especially in recent studies. Studies in the literature usually include immunological examinations of patient blood or tumor tissue.
Immune checkpoints are molecules that have become popular especially after the Nobel Prize in 2018, and are important in revealing the relationship between cancer and the immune system. Programmed Cell Death Protein-1 (PD-1) and its ligand, PD-L1, is an immune checkpoint that acts by blocking T cell receptor signal transduction and auxiliary stimuli. T cell immunoglobulin and mucin domain 3 (TIM-3) are mostly expressed on T cells, Tregs, dendritic cells, B cells, macrophages, natural killer cells (NK) and mast cells that produce interferon-(10). Impairment in regulation of TIM-3 expression has been associated with autoimmune diseases. High TIM-3 expression is associated with suppression of T cell responses and T cell depletion, which is characterized by loss of T cell functions during chronic viral infections and during tumor development. With the clinical success of immune checkpoint inhibitors such as ipilimumab and nivolumab for melanoma and lung cancer, immune checkpoints have attracted more attention.
There are many publications in the literature evaluating immunological markers from ascites fluid samples for various reasons. In these studies, T and B cell subtypes were examined from ascites fluid samples taken from patients with ascites, especially ovarian cancer and liver cirrhosis. In the only study on gastrointestinal cancers, immunophenotyping was performed in intraabdominal ascites and blood in 22 advanced gastrointestinal tumor patients and some cell subgroups were associated with worse clinical outcome. In the literature, there is no study on cytokine analysis from intra-abdominal ascites fluids specific to colorectal cancer.
In our study, it is aimed to evaluate whether there is a difference in intraabdominal ascites fluid immune checkpoints level in patients with advanced colorectal cancer patients compared to patients without malignancy.
