Colorectal Cancer and Common Psychiatric Disorders: A Two-sample Mendelian Randomization Study

摘要

摘要: 目的：基于双样本孟德尔随机化(2-Sample Mendelian randomization, 2-Sample MR)分析结直肠癌与常见精神类疾病的因果关系。方法：依托于公共数据库中结直肠癌与精神类疾病的GWASs数据，通过逆方差加权、MR-Egger和中位数加权三种方法评估结直肠癌与抑郁症、焦虑症、双向情感障碍和精神分裂症之间的关系，最后通过敏感性分析评估结论的可信度和稳健性。结果：逆方差加权显示结直肠癌与抑郁症(OR=0.995，95%CI：0.995~1.000，P=0.090)、焦虑症(OR=1.001，95%CI：1.000~1.001，P=0.099)、精神分裂症(OR=1.003, 95%CI：0.9603~1.0473，P=0.899)之间没有因果关系；但与双向情感障碍风险降低存在因果关系(OR=0.937，95%CI：0.8919~0.9849，P=0.010)。结论：研究表明，结直肠癌与抑郁症、焦虑症和精神分裂症无因果关系，但结直肠癌与双向情感障碍风险降低可能存在因果关联，同时印证了肠脑轴的存在。

Abstract:
　　Objective: This study aimed to elucidate the causal relationships between colorectal cancer (CRC) and prevalent psychiatric disorders using a two-sample Mendelian randomization approach, and provide evidence supporting the gut-brain axis (GBA) hypothesis.

　　Methods: Utilizing publicly available GWAS datasets, we explored the connections between CRC and various psychiatric disorders, including depression, anxiety, bipolar disorder, and schizophrenia. We applied three statistical analyses: inverse variance weighting, MR-Egger, and median weighting. Sensitivity analyses were conducted to ensure the reliability and validity of our results.
