Liver Disease as a Potential Risk Factor for Colorectal Cancer: A Community Hospital Experience

Background: Liver disease (LD) is a common pathology worldwide. Many patients remain asymptomatic and undiagnosed. Colorectal cancer (CRC) is a prevalent neoplasm and a leading cause of cancer-related deaths globally. Multiple studies suggest that inflammation in the liver could drive the initiation of colorectal cancer. Methods: This five-year (2018-2022) case-control study included 274 patients diagnosed with CRC and adenomas at a community hospital in Houston, Texas. Each patient's medical record was reviewed for pre-existing LD, including steatosis, cirrhosis, primary biliary cirrhosis, and Hepatitis B and C infections. This study aims to investigate the association between LD and CRC risk and assess differences by gender, race, and ethnicity. The study cohort comprised 124 (45.3%) women and 150 (54.7%) men. Data were compared and analyzed using a Chi-squared test for independence and binomial logistic regression. A p-value of < 0.05 was considered statistically significant. Results: Patients with LD had a two-fold increase in the odds of developing CRC compared to those without LD, in both univariate and multivariate analyses (OR 2.13 {95% CI 1.30-3.49}, p = 0.003 / OR 2.30 {95% CI 1.37-3.87}, p = 0.002, respectively). The chi-square test revealed that the association between CRC and LD was stronger in women than in men (p = 0.018 and p = 0.056, respectively). Conclusion: Our study establishes a positive correlation between LD and CRC development, suggesting LD is a potential risk factor for CRC, particularly in women. Future research directions include exploring the underlying mechanisms of this association, evaluating the utility of early CRC screening in individuals with LD, and assessing the impact of interventions targeting LD on CRC incidence and mortality.
