ARTICLE HIGHLIGHTS
Research background
The development of convolutional neural network (CNN) model as a novel diagnostic technology has promoted the screening, early detection, and improved prognosis of esophageal cancer and high-grade dysplasia (HGD).
Research motivation
Explore the diagnostic value of CNN model for esophageal cancer and HGD, and provide basis for its clinical application.
Research objectives
Conduct a meta-analysis of the diagnostic accuracy of CNN models for the diagnosis of esophageal cancer and HGD.
Research methods
We searched for relevant studies in various search engines, evaluated the diagnostic accuracy of CNN models, and calculated the diagnostic test accuracy with a bivariate method and hierarchical summary receiver operating characteristic method. Meta-regression and subgroup analyses were used to identify sources of heterogeneity.
Research results
After processing 28 items of still image-based and video-based analysis in statistics, CNN models have been proven to have high accuracy and diagnostic efficiency in diagnosing esophageal cancer or HGD and predicting the invasion depth of esophageal cancer.
Research conclusions
CNN-based image analysis in diagnosing esophageal cancer and HGD is an excellent diagnostic method with high sensitivity and specificity.
Research perspectives
A thorough evaluation of the accuracy of diagnosis in esophageal cancer and HGD requires further investigation. Large-scale trials are needed to assess performance and predict clinical values.
