Hepatocellular carcinoma tumor tissue (HCC tumor tissue)

Hepatocellular carcinoma tumor tissue refers to the primary malignant tumor derived from hepatocytes (liver cells), characterized by significant molecular and morphological heterogeneity. HCC tumor tissue commonly harbors mutations in TERT promoter, TP53, and CTNNB1, and exhibits variable histological features including trabecular, solid, and clear cell patterns. The biological behavior includes uncontrolled proliferation, evasion of apoptosis, metabolic reprogramming, and immune escape. Therapeutic targeting in HCC typically focuses on molecular pathways active within the tumor (such as VEGF, PD-1/PD-L1, TGF-β, WNT/β-catenin, and mTOR pathways), and systemic therapy selection often involves molecular profiling and biomarker assessment due to tissue heterogeneity[1][2][3][4][6].
