Abstract
- Simple Summary: This retrospective study focused on 23 patients diagnosed with Hepatocellular Carcinoma (HCC), utilizing the Liver Imaging Reporting and Data System (LI-RADS) for classification. This system aids in the non-invasive diagnosis of HCC, potentially eliminating the need for a diagnostic biopsy. Patients were selected based on their diagnosis, confirmed either via imaging methods that identified advanced liver nodules or via histopathological findings consistent with HCC, including specific protein markers. The study aimed to assess the histopathological changes resulting from prior local interventions, such as trans-arterial chemoembolization or radiofrequency ablation, and their impact on the tumor's response to subsequent immune therapies. Key findings indicated variations in alpha-fetoprotein levels and increased expression of the immune marker PD-L1 in untreated patients, suggesting a more aggressive cancer progression in these individuals. The study's conclusions support the use of liver biopsy in refining therapeutic approaches for HCC, particularly in recurrent cases post-intervention, to enhance personalized immune therapy strategies. Background: The Liver Imaging Reporting and Data System (LI-RADS) combines standardized terminology with a classification system for imaging findings in patients with HCC, therefore rendering diagnostic biopsy unnecessary in many cases. This retrospective study included 23 patients with a biopsy diagnosis of HCC, performed either before or after local interventional procedures, in order to evaluate the histopathologic changes induced by previous procedures and their potential influence on the response to immune therapy. Material and Methods: The study encompassed a cohort of patients diagnosed with Hepatocellular Carcinoma (HCC). Diagnosis was established via contrast-enhanced computer tomography or magnetic resonance imaging that identified LI-RADS-5 nodules in conjunction with historical liver disease and elevated alpha-fetoprotein (AFP) levels or via histological examination confirming positivity for glypican3, heat shock protein 70, and glutamine synthetase. The study detailed the liver disease etiology, LI-RADS scores, characteristics and dimensions of HCC nodules, serum AFP concentrations, Edmondson–Steiner grading, and the expression of programmed cell death ligand 1 (PD-L1) in the tumor cells. Results: Among the study's cohort of Hepatocellular Carcinoma (HCC) patients, a portion had not received any prior treatments, while the remainder experienced local HCC recurrence following trans-arterial chemoembolization or radiofrequency ablation. Observations indicated elevated alpha-fetoprotein (AFP) levels in those who had not undergone any previous interventions, showing statistical significance. The Edmondson–Steiner classification predominantly identified grade III differentiation across patients, irrespective of their treatment history. Furthermore, an increase in intra-tumoral programmed cell death ligand 1 (PD-L1) expression was noted in patients who had not been subjected to previous therapies. Conclusion: Liver biopsy offers valuable insights for patients with Hepatocellular Carcinoma (HCC), assisting in the tailoring of immune therapy strategies, particularly in cases of recurrence following prior local interventions.
