While immunotherapy brings benefits to patients, it also results in a series of immune-related adverse events (irAEs) . Increasing evidence suggests that the gut microbiome is critical for immunotherapy response and the development of irAEs.  \nMethods: In this prospective study, we recruited 95 patients with advanced/ unresectable gastrointestinal cancers treated with immunotherapy and report a comprehensive analysis of the association of the gut microbiome with irAEs. Metagenome sequencing was used to analyze the differences in bacterial composition and metabolic pathways of baseline fecal samples.  \nResults: In summary, we identified bacterial species and metabolic pathways that might be associated with the occurrence of irAEs in gastric, esophageal, and colon cancers. Ruminococcus callidus and Bacteroides xylanisolvens were enriched in patients without severe irAEs. Several microbial metabolic pathways involved in the urea cycle, including citrulline and arginine biosynthesis, were associated with irAEs. We also found that irAEs in different cancer types and toxicity in specific organs and the endocrine system were associated with different gut microbiota profiles. These findings provide the basis for future mechanistic exploration.  \nKEYWORDS  \nimmune-related adverse event, gut microbiome, ","cbCaibaVZPAlLMkF","https://ap.wps.com/l/cbCaibaVZPAlLMkF","pdf",6246067,"English","# Introduction\n## Background and clinical need for predicting irAEs\n# Methods\n## Prospective cohort and metagenome sequencing approach\n# Results\n## Taxa and metabolic pathways linked to irAEs\n## Links across cancer types and organ/endocrine toxicities","[{\"question\":\"What is the purpose of this study?\",\"answer\":\"To determine whether gut microbiome characteristics are associated with immune-related adverse events in gastrointestinal cancer patients treated with immune checkpoint inhibitors.\"},{\"question\":\"How were the gut microbiome data collected and analyzed?\",\"answer\":\"Baseline fecal samples were analyzed using metagenome sequencing to compare bacterial composition and metabolic pathways.\"},{\"question\":\"Which microbiome findings were associated with irAEs?\",\"answer\":\"Certain bacterial species were enriched in patients without severe irAEs, while urea-cycle related metabolic pathways were associated with irAEs.\"},{\"question\":\"Do irAEs differ across cancer types and organs?\",\"answer\":\"Yes.
