Operative link for gastritis assessment vs operative link on intestinal metaplasia assessment

Figure 1 Distribution of patients by the two considered staging systems (operative link for gastritis assessment vs operative link on intestinal metaplasia). OLGA: Operative link for gastritis assessment; OLGIM: Operative link on intestinal metaplasia.

Figure 2 Distribution of preneoplastic/neoplastic lesions in the two considered staging-systems (i. e., operative link for gastritis assessment (OLGA)] and operative link on intestinal metaplasia assessment stages (OLGIM)]. ¹Diffuse-type (signet ring) gastric cancer. GC: Gastric cancer; LG-IEN: Low-grade intraepithelial neoplasia; HG-IEN: High-grade intraepithelial neoplasia.

Figure 3 One of two gastric cancers developing in operative link for gastritis assessment stage III, but the operative link for gastritis assessment stage II, gastric mucosa. Representative images of 6 biopsy samples (3 from the mucosecreting/antral compartment, 1 from the lesion, and 2 from the oxyntic/corpus compartment) labeled according to site of origin (A: antral/angular; GC: gastric cancer; C: corpus), showing the percentages of atrophic/metaplastic lesions and the consequent operative link for gastritis assessment/operative link on intestinal metaplasia assessment stages.
