Association between diverticular disease and prevalence of colorectal adenomatous polyps or adenocarcinomas

Diverticular disease and colorectal adenoma/adenocarcinoma



Adenomatous polyp, Colon adenocarcinoma, Diverticular disease, High grade dysplasia, Villous adenomatous polyp


Background/Aim: Although the link between diverticular disease (DD) of the colon and colon polyp is known, the relationship between colon adenocarcinoma is not clear. This study evaluated the association between DD and adenomatous polyp or colon adenocarcinoma.

Methods: Patients who underwent colonoscopy for the first time in 2020-2021 were evaluated and included in this retrospective cohort study. Patients with a previous history of cancer diagnosis, colon surgery, DD, and inflammatory bowel disease were excluded from the study. Age, gender, colonoscopy indications, colonoscopy diagnoses, presence of DD, characteristics of polyps (pathology, diameter, number, localization), and presence of adenocarcinoma were recorded. Obtained data were analyzed between DD and non-DD groups.

Results: A total of 2633 patients were included in the study. The prevalence of DD was 16.4%. Colon adenocarcinoma was detected in 4.7%. The adenomatous polyp rate was 14.1%. A significantly higher rate of adenomatous polyps was detected in the DD group compared to the non-DD group (19.7% vs. 12.9%; P = 0.001). Higher rates of high-grade dysplasia (3.0 vs. 1.1%; P = 0.002) and colon adenocarcinoma (7.2% vs. 4.2%; P = 0.008) were observed in the DD group also. In logistic regression analyses, it was observed that the presence of concomitant DD increases the risk of adenomatous polyps (OR: 1.469, 95% CI: 1.158–1.865), the risk of adenomatous polyps with positive villous component (OR: 2.378, 95% CI: 1.437–3.934), the risk of adenomatous polyps with high-grade dysplasia (OR: 2.822, 95% CI: 1.426–5.582), and the risk of colon adenocarcinoma (OR: 2.953, 95% CI: 1.445–6.533).

Conclusion: DD is associated with precancerous lesions of the colon (adenomatous polyp, villous adenoma, high-grade dysplasia) and colon adenocarcinoma. Further studies are needed to investigate its association with colon carcinogenesis and its role and value in cancer screening.
