    Immune checkpoint inhibitors (ICIs) have transformed cancer therapy, but clinical responses are highly variable and inconsistent.

  • 2

    The gut microbiome is implicated in modulating ICI efficacy, yet findings remain inconsistent at the taxonomic level.

  • 3

    A bibliometric analysis of 2,195 publications revealed a shift toward clinically oriented themes in microbiome-ICI research.

    Despite variability in response-associated taxa, functional integration suggests convergence in immunomodulatory pathways.

  • 5

    The study advocates for a function-based framework for biomarker discovery and microbiome-directed immunomodulation.
