Abstract

Background: Colorectal polyps are common gastrointestinal lesions with potential progression to colorectal cancer (CRC). Narrow Band Imaging (NBI), combined with the NBI International Colorectal Endoscopic (NICE) classification, enhances visualization of mucosal and vascular patterns, enabling real-time differentiation between neoplastic and non-neoplastic polyps. Detecting and removing precancerous polyps at an early stage helps lower the incidence and death rates of colorectal cancer. Objective: To evaluate the association between NBI findings based on the NICE classification and histopathological outcomes of colorectal polyps. Methods: A cross-sectional descriptive study was conducted on 206 patients with colorectal polyps ≥5mm who underwent colonoscopy using NBI at Hoan My Cuu Long General Hospital from June 2024 to April 2025. Polyps were classified according to the NICE system and were determined histopathologically. Results: A total of 263 polyps were analyzed. NICE I, II, and III accounted for 30.0%, 65.4%, and 4.6%, respectively. Histologically, 55.6% were neoplastic and 44.4% non-neoplastic, including 4.6% invasive cancers. There was a significant correlation between the NICE classification and histopathology (p<0.001). The sensitivity and specificity of NICE classification in identifying malignant polyps were 83.3% and 99.6%, respectively. The area under the ROC curve was 0.941 (95% CI: 0.855–1.000). Conclusion: NBI using the NICE classification provides high diagnostic accuracy in differentiating malignant and benign colorectal polyps, supporting appropriate clinical decision-making during colonoscopy.
