Gut bacteria may help immune therapy work better against tumors

AI simplified

Abstract

Immune-checkpoint inhibitors (ICIs) have improved survival in cancer patients, but durable benefits are limited.

  • A limited number of patients experience sustained benefits from ICIs.
  • The gut microbiome plays a significant role in influencing immune responses.
  • There is potential for the gut microbiome to predict responses to ICI treatment.
  • Mechanistic analyses and clinical trials suggest a relationship between gut microbiome and ICI efficacy.
  • Research is ongoing to develop strategies leveraging the gut microbiome to improve ICI treatment outcomes.
