Abstract
Immune checkpoint inhibitors (ICIs) are widely used due to their effectiveness in treating various tumors. Immune-related adverse events (irAEs) are defined as adverse effects resulting from ICI treatment. Gastrointestinal irAEs are a common type of irAEs characterized by intestinal side effects, such as diarrhea and colitis, which may lead to the cessation of ICIs. Although irAE gastritis is rarely reported, it may lead to serious complications such as gastrorrhagia. Furthermore, irAE gastritis is often difficult to identify early due to its diverse symptoms. Although steroid hormones and immunosuppressants are commonly used to reverse irAEs, the best regimen and dosage for irAE gastritis remains uncertain. In addition, the risk of recurrence of irAE gastritis after the reuse of ICIs should be considered. In this editorial, strategies such as early identification, pathological diagnosis, management interventions, and immunotherapy rechallenge are discussed to enable clinicians to better manage irAE gastritis and improve the prognosis of these patients.
Core Tip: Immune checkpoint inhibitor (ICI)-related gastritis is rare but may lead to serious complications such as gastrorrhagia. Biopsy under esophagogastroduodenoscopy is the gold standard for diagnosis. Specifically, this article discusses strategies for treating ICI-related gastritis, including early recognition, pathological diagnosis, management interventions, and rechallenge with immunotherapy, providing clinicians with valuable consultations to enable cancer patients to benefit early from treatment.
