Brief Summary
Colorectal cancers are the third most common cancer in the world. In advanced stages of colorectal cancers, peritoneal carcinomatosis and intraabdominal acid development occur. Although stomach cancer is the 5th most common cancer in the world, it is the third cancer with the highest mortality. Pancreatic cancer is one of the highest mortality cancers worldwide. Likewise, in advanced stages of stomach and pancreatic cancer, peritoneal carcinomatosis and intra- abdominal acid development occur. It is known that the immune system plays an important role in tumor development or destruction of tumor. Recent studies have shown that tumor cells develop escape mechanisms in the tumor microenvironment to escape from host immunity. It has been reported that differentiation of T cells towards Th2 and regulatory T cells is also effective in tumor progression(6). Changes in the tumor microenvironment and immune checkpoints are important mechanisms that lead to escape from the immune system. Immune checkpoints are on the agenda especially after 2018 Nobel Prize and they are important molecules in revealing the relationship.In our study, it is aimed to evaluate whether there is a difference in immune control points in patients with end-stage colorectal cancer, gastric cancer and pancreatic cancer compared to patients without malignancy, and the relationship of these parameters with patient survival and tumor spread mechanisms.

Interventions
Measuring the sCD25 (IL-2Ra), 4-1BB, B7.2 (CD86), Free Active TGF-β1, CTLA-4, PD-L1, PD-1, Tim-3, LAG-3, Galectin-9 levels with flow cytometry
Eligibility Criteria
Patients with intraabdominal ascites with benign reasons (liver cirrhosis, Congestive heart failure, etc.) will be the control group, and patients with advanced stage colorectal cancer, gastric cancer and pancreatic cancer who develop malignant ascites will be the gastrointestinal cancer group
You may qualify if:
- Patients with intraabdominal ascites with benign reasons (liver cirrhosis, Congestive heart failure, etc.) for control group
- Patients with advanced stage colorectal cancer, gastric cancer and pancreatic cancer who develop malignant ascites for gastrointestinal cancer group
You may not qualify if:
