Toward a future role for liver biopsy in HCC: literature evidence and survey-based perspectives from Korean experts

The role of liver biopsy in hepatocellular carcinoma (HCC) is being re-evaluated in the era of precision oncology and biomarker-driven systemic therapy. Although histopathological examination remains the diagnostic gold standard, HCC is unique among solid tumors in that accurate non-invasive imaging criteria allow diagnosis without routine biopsy in selected clinical settings. However, increasing biological heterogeneity, expanding therapeutic options, and the growing need for molecular stratification have renewed interest in tissue-based evaluation. Recent international guidelines have gradually broadened the indications for liver biopsy, particularly in selected diagnostic scenarios, prior to systemic therapy, and for molecular profiling. Beyond diagnostic confirmation, liver biopsy provides important information for histological subtyping, prognostic stratification, and biomarker discovery. Advances in immunohistochemistry, next-generation sequencing, and artificial intelligence-assisted pathology have further enhanced the clinical value of tumor tissue. In parallel, contemporary cohort studies indicate that liver biopsy is associated with low complication rates when modern techniques and standardized peri-procedural management are applied. Despite these advances, the integration of liver biopsy into routine clinical practice remains limited. To contextualize this gap, the Korean Liver Cancer Association conducted a nationwide survey of HCC specialists. The survey showed that liver biopsy is infrequently performed in current practice due to perceived procedural risks and limited immediate impact on therapeutic decision-making. Taken together, accumulating evidence supports a reappraisal of the clinical role of liver biopsy in HCC. Optimizing procedural safety, standardizing indications, and integrating tissue-based molecular insights into therapeutic decision-making may help bridge the gap between emerging evidence and real-world practice.
