Hepatocellular carcinoma tumor thrombus entering the inferior vena cava treated with percutaneous RF ablation: a case report.

Hepatocellular carcinoma (HCC) is the most common form of liver cancer. In advanced cancer stages (metastatic disease and/or vascular invasion), the generally accepted standard of care is systemic therapy using sorafenib as first-line treatment and, recently, regorafenib and nivolumab as second-line treatment, but the quality of life and the prognosis of patients remain very poor. Our paper reports a case of US-guided radiofrequency ablation (RFA) of both intraparenchymal HCC and inferior vena cava tumor thrombus.
