Abstract
BACKGROUND

Colorectal polyps are commonly observed in patients with chronic liver disease (CLD) and pose a significant clinical concern because of their potential for malignancy.

AIM

To explore the clinical characteristics of colorectal polyps in patients with CLD, a nomogram was established to predict the presence of adenomatous polyps (AP).

METHODS

Patients with CLD who underwent colonoscopy at Tianjin Second People’s Hospital from January 2020 to May 2023 were evaluated. Clinical data including laboratory results, colonoscopy findings, and pathology reports were collected. Key variables for the nomogram were identified through least absolute shrinkage and selection operator regression, followed by multivariate logistic regression. The performance of the model was evaluated using the area under the receiver area under curve, as well as calibration curves and decision curve analysis.

RESULTS

The study enrolled 870 participants who underwent colonoscopy, and the detection rate of AP in patients with CLD was 28.6%. Compared to individuals without polyps, six risk factors were identified as predictors for AP occurrence: Age, male sex, body mass index, alcohol consumption, overlapping metabolic dysfunction-associated steatotic liver disease, and serum ferritin levels. The novel nomogram (AP model) demonstrated an area under curve of 0.801 (95% confidence interval: 0.756-0.845) and 0.785 (95% confidence interval: 0.712-0.858) in the training and validation groups. Calibration curves indicated good agreement among predicted and actual probabilities (training: χ2 = 11.860, P = 0.157; validation: χ2 = 7.055, P = 0.530). The decision curve analysis underscored the clinical utility of the nomogram for predicting the risk of AP.

CONCLUSION

The AP model showed reasonable accuracy and provided a clinical foundation for predicting the occurrence of AP in patients with CLD, which has a certain predictive value.

Core Tip: This study is the first effort to develop and validate a predictive model for assessing the risk of adenomatous polyps in patients with chronic liver disease. Based on six risk factors, the developed adenomatous polyps model will function as an effective means of identifying and stratifying patients undergoing management for chronic liver disease, thereby helping to reduce the risk of colorectal cancer in these individuals.
