This systematic review and meta-analysis evaluated the risk of gastric neoplasms in patients with autoimmune gastritis (AIG) and pernicious anemia (PA). The study found that AIG is associated with increased risks of dysplasia (5.35 per 1,000 person-years) and neuroendocrine tumors (NETs) (14.56 per 1,000 person-years), while PA significantly elevates gastric cancer risk (relative risk, 2.78).
Key findings
- Pooled incidence rates for gastric cancer in AIG patients were 2.08 per 1,000 person-years.
- Dysplasia incidence in AIG patients was significantly elevated at 5.35 per 1,000 person-years.
- NET incidence in AIG patients was 14.56 per 1,000 person-years.
- PA was associated with a higher gastric cancer risk (relative risk, 2.78).
Why it matters
Understanding the neoplastic risks associated with autoimmune gastritis and pernicious anemia is crucial for clinicians, as it informs surveillance strategies and management of patients at risk for gastric neoplasms.
