Key Points

To evaluate the association between autoimmune gastritis and the risk of gastric neoplasms.
Conducted a systematic review and meta-analysis on patients with autoimmune gastritis.
Performed stratified subgroup analyses to explore heterogeneity in gastric cancer and neuroendocrine tumors risks.
Included evaluations of endoscopic surveillance recommendations.
Autoimmune gastritis was linked to increased risks of dysplasia and neuroendocrine tumors.
Gastric cancer risk may be underestimated due to significant heterogeneity in results.
Pernicious anemia was specifically associated with a higher risk of gastric cancer.

Implication

Systematic review assesses gastric cancer and neuroendocrine tumors risk in autoimmune gastritis, suggesting endoscopic monitoring implications.
