Gut microbiome-driven modulation of the tumor immune microenvironment optimizes dual checkpoint blockade in advanced non-small-cell lung cancer

Gut microbiota diversity and SCFA-producing bacteria are associated with improved efficacy of I-N. Baseline gut microbiota diversity may help identify patients who are more likely to have improved outcomes with I-N plus chemotherapy than with I-N alone. These findings highlight the potential of gut microbiota as a novel biomarker for dual checkpoint blockade in NSCLC may contribute to advancing personalized medicine.
