Background:
The aim of this study was to determine whether inflammatory bowel disease (IBD) is associated with the risk of developing prostate cancer (PCa) through a population-based study.
Materials And Methods:
Male patients aged ≥40 years, diagnosed with IBD from 2010 to 2013 and without IBD were identified and followed-up till 2019. A matched cohort of male patients with and without IBD in a ratio of 1:4 was created based on age, income level, and Charlson comorbidity index. Multivariate Cox regression analysis was conducted to evaluate the association of IBD with the prescence of PCa and PCa requiring definitive treatment within 1 year of diagnosis. The hazard ratio (HR) and 95% confidence interval (CI) were stratified by Crohn's disease, ulcerative colitis (UC), and subtypes.
Results:
After matching, 15,751 IBD patients and 62,346 controls were analyzed. Over a median follow-up period of 96 months, the HR for PCa was significantly increased in patients with IBD (HR: 2.44; 95% CI: 2.08-2.86, P < 0.001). IBD was also associated with PCa requiring definitive treatment within 1 year (HR: 2.67; 95% CI: 2.09-3.42, P < 0.001). In subgroup analysis, UC (HR: 2.83; 95% CI: 2.18-3.69, P < 0.001) showed higher risk of PCa requiring definitive treatment than for Crohn's disease (HR: 2.21; 95% CI: 1.43-3.43, P = 0.0004). All-cause death in patient-diagnosed PCa was the highest in UC of pancolitis (HR: 2.26; 95% CI: 0.99-5.16, P = 0.054), and the lowest in ulcerative proctitis (HR: 0.35; 95% CI: 0.21-0.60, P = 0.0001).
Conclusion:
IBD was associated with an increased incidence of PCa in our matched analysis.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
