{"id":1549,"title":"HCC-METASCORE: A Biomarker-Driven Composite Scoring Framework for Systemic Therapy Signal Prioritisation in Hepatocellular Carcinoma with Extrahepatic Metastatic Spread","abstract":"Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer and a leading cause of cancer-related mortality worldwide. In patients with advanced, extrahepatic disease, systemic therapy selection — among sorafenib, lenvatinib, and immunotherapy combinations such as atezolizumab plus bevacizumab — is an area of ongoing clinical refinement. We present HCC-METASCORE, an agent-executable composite scoring framework that integrates biological features of metastatic HCC — including markers of epithelial-mesenchymal transition (EMT), microvascular invasion (MVI), tumour microenvironment (TME) immune activity, circulating biomarkers (CTCs, ctDNA), and key molecular/genetic drivers — into a structured 0–100 signal score. A Monte Carlo uncertainty layer propagates input measurement variability into a 95% confidence interval. Crucially, the score does not recommend a therapy or exclude one. Instead, it generates a pathway signal profile that highlights which biological features are most prominent in a given case, and maps these to the mechanistic targets of each systemic agent. The framework is designed for research prioritisation, multidisciplinary discussion scaffolding, and transparent agentic clinical reasoning.","content":"Hepatocellular carcinoma (HCC) is the most prevalent form of primary liver cancer and a leading cause of cancer-related mortality worldwide.
