CTLA-4 is a crucial molecule in T-cell immune regulation, and its genetic polymorphism is associated with an increased risk of various autoimmune diseases and tumors. This study aims to explore the association between CTLA-4 gene polymorphism and susceptibility to colorectal cancer.First, we searched relevant literature and databases, collected studies on the association between CTLA-4 gene polymorphism and colorectal cancer, and then screened and analyzed them. Second, we selected studies that met the inclusion criteria for meta-analysis, calculated the OR value and 95% CI value, and drew a forest plot. Finally, we conducted robustness analysis and subgroup analysis of the results.Expected results: CTLA-4 gene polymorphism is associated with susceptibility to colorectal cancer and may become a potential risk factor for colorectal cancer.精品文档---下载后可任意编辑Keywords: CTLA-4; gene polymorphism; colorectal cancer; susceptibility; meta-analysis.
