A novel method of grading gastric intestinal metaplasia based on the combination of subtype and distribution.

ABSTRACT:

Background

Studies have shown the value of subtypes and distribution of gastric intestinal metaplasia (GIM) for prediction of gastric cancer. We aim to combine GIM subtypes and distribution to form a new scoring system for GIM.

Methods

This was a cross-sectional study. No GIM, type I, II, and III GIM of gastric antrum and corpus scored 0-3 points respectively. Then the severity of the whole stomach was calculated in two ways: 1. The gastric antrum and corpus scores were added together, with a score ranging from 0 to 6, which named "Subtype Distribution Score of Gastric Intestinal Metaplasia (SDSGIM)". 2. Direct classification according to a table corresponding to that of OLGIM. We compared the SDSGIM among benign lesions, dysplasia, and cancer and drew receiver operating cha
