Risk Factors for Colorectal Cancer in Inpatients With Ulcerative Colitis: A Nationwide Cross-Sectional Analysis

Abstract

The objective is to study the demographic and geographical factors that increase the risk of colorectal cancer (CRC) in inpatients with ulcerative colitis (UC) and evaluate the mortality risk and hospitalization outcomes in terms of length of stay (LOS) and cost of care in patients with CRC in UC. MethodsWe conducted a cross-sectional study using the nationwide inpatient sample (NIS, 2019). We included 78,835 inpatients (age 15-65 years) hospitalized on emergency-based admissions with a primary diagnosis of UC. The study sample was divided by the presence of CRC. Categorical and continuous data were analyzed using Pearson's chi-square test and independent-sample t-test respectively. Independent binomial logistic regression models were used to evaluate the odds ratio (OR) of predictors associated with CRC in patients with UC compared to non-CRC. ResultsThe prevalence of CRC in inpatients with UC was 0.2%, and the mean age for admission of patients with UC with CRC was 49.6 years (SD ± 10.29). A directly proportionate relationship exists between increasing age and the risk of CRC in UC inpatients with 10 times higher odds seen in 51-65 years of age (OR 10.0, 95% CI 5.11-19.61). Males (OR 2.15, 95% CI 1.49-3.08) and Hispanics (OR 1.69, 95% CI 1.04-2.74) are at higher odds for CRC compared to their counterparts. Acquired immunodeficiency syndrome (AIDS) was associated with increased odds (OR 6.23, for CRC in UC inpatients. There existed an increased association for CRC in UC inpatients with complicated hypertension, and alcohol and drug abuse but was statistically non-significant. As per the adjusted regression model, CRC in UC inpatients increased the risk of in-hospital mortality (OR 41.09,. ConclusionsCRC was more prevalent in middle-aged Caucasian males with UC and those with chronic comorbidities including complicated diabetes and hypertension, alcohol abuse, and AIDS. Patients with UC and AIDS were found to have greater odds of developing CRC. A high index of clinical suspicion is needed in the management of these patient groups as the inpatient mortality risk was higher in UC inpatients with CRC.

“…Colorectal cancer (CRC) is one of the most common cancers and has been reported as the second type of cancer leading to death (Kommuru et al 2022). CRC is recorded to be responsible for 10% of all cancer incidences and 9.4% of all cancer-related deaths, worldwide (Krasteva and Georgieva 2022).…”
