This study provides a comprehensive genomic and immunological analysis of the transition from premalignant dysplastic nodules to very early hepatocellular carcinoma (veHCC). Researchers discovered that while TERT alterations often exist in early lesions, the actual shift to malignancy is primarily driven by the accumulation of copy number alterations (CNAs) rather than single-nucleotide mutations. Interestingly, premalignant nodules typically exist in an immune-desert state, appearing inactive despite the surrounding diseased liver tissue. As cancer emerges, the study identifies two distinct…
