Diagnostic value of JNET classification under narrow-band imaging for colorectal laterally spreading tumors
Objective
To evaluate the diagnostic efficacy of Japan Narrow Band Imaging Expert Team(JNET) classification under narrow-band imaging (NBI) for colorectal laterally spreading tumors.
Methods
Data of 170 laterally spreading tumors (LST) detected by NBI and pigment dyeing were reviewed in the retrospective study. JNET classification under NBI was used for rediagnosis based on surface pattern and vessel pattern. Pit pattern(PP) was observed under pigment dyeing using PP classification. The results were compared with histologic results after endoscopic resection or surgery.
Results
The diagnostic sensitivity, specificity, positive predictive value, negative predictive value and accuracy of JNET classification and PP classification were 92.2% VS 70.3%, 82.3% VS 85.0%, 74.7% VS 72.6%, 94.9% VS 83.5%, 85.9% VS 79.7%, respectively (P=0.159). The consistency rates of JNET classification and PP classification in predicting shallow invasion depth of LST were 6.1% and 8.3% respectively and the consistency rates in predicting deep invasion were 30.8% and 4.8%, respectively.
Conclusion
JNET classification under NBI is effective in predicting malignant laterally spreading tumors, however, its efficacy in predicting tumor invasion depth is unsatisfied. PP classification can be used to improve the diagnostic accuracy for those with diagnostic difficulty.

期刊介绍:
Chinese Journal of Digestive Endoscopy is a high-level medical academic journal specializing in digestive endoscopy, which was renamed Chinese Journal of Digestive Endoscopy in August 1996 from Endoscopy.
Chinese Journal of Digestive Endoscopy mainly reports the leading scientific research results of esophagoscopy, gastroscopy, duodenoscopy, choledochoscopy, laparoscopy, colorectoscopy, small enteroscopy, sigmoidoscopy, etc. and the progress of their equipments and technologies at home and abroad, as well as the clinical diagnosis and treatment experience.
The main columns are: treatises, abstracts of treatises, clinical reports, technical exchanges, special case reports and endoscopic complications.
The target readers are digestive system diseases and digestive endoscopy workers who are engaged in medical treatment, teaching and scientific research.
Chinese Journal of Digestive Endoscopy has been indexed by ISTIC, PKU, CSAD, WPRIM.
