The gut-liver axis: exploring microbial dysbiosis and specific biomarkers in hepatocellular carcinoma

A specific gut bacterial signature distinguishes liver cancer patients with high accuracy, positioning microbiome analysis as a future screening approach.

Meta-analysis of 13 studies identified a cross-site microbial signature achieving AUC 0.96 for HCC discrimination in liver microbiota, with Mendelian randomization supporting a causal role for Streptococcus in HCC development. Results position microbiome biomarkers as a promising HCC screening approach awaiting prospective validation.
