Core Tip

Core Tip: With the widespread application of immunotherapy, the incidence of immune-related gastritis has increased than before. However, the diagnosis of immune-related gastritis is somewhat challenging due to its atypical clinical symptoms and lack of specific findings in serological tests. Although endoscopy and histopathological examination are valuable for immune-related gastritis diagnosis, differential diagnosis for different diseases (such as autoimmune gastritis) is still necessary. The treatment of immune-related gastritis should be individualized based on the patient's specific situation. The occurrence and management of immune-related adverse events (irAEs), as well as whether to continue treatment with immune checkpoint inhibitors (ICIs) after resolution, are major challenges in clinical practice. Studies have shown that for patients with grade 2-3 irAEs, ICI treatment can be considered for reinitiation when symptoms regress to grade 0-1, preferably using a different class of ICIs. For grade 4 irAEs, ICIs should be permanently discontinued.
