Efficacy and Safety of Sorafenib in Unresectable Hepatocellular Carcinoma with Bile Duct Invasion

The Treatment of Hepatocellular Carcinoma with Major Vascular Invasion

Vascular invasion of hepatocellular carcinoma involves tumor plugs in the main trunk of the portal vein, bile ducts, and veins, and it indicates poor prognosis. It is often associated with portal hypertension, which requires evaluation and management. Treatment includes hepatic resection, systemic pharmacotherapy, hepatic arterial infusion chemotherapy, and radiation therapy. Recurrence rates post-hepatic resection are high, and systemic drug therapy often has limited therapeutic potential in patients with a poor hepatic reserve. Single therapies are generally inadequate, necessitating combining multiple therapies with adjuvant and systemic pharmacotherapy before and after hepatectomy. This narrative review will provide an overview of the treatment of hepatocellular carcinoma with vascular invasion.

Complete response to tremelimumab plus durvalumab treatment in hepatocellular carcinoma with a bile duct tumor thrombus: A case report

Tremelimumab plus durvalumab (Dur/Tre) is the first-line treatment for advanced hepatocellular carcinoma (HCC) worldwide. The present report describes the case of a 68-year-old man diagnosed with advanced HCC and a bile duct tumor thrombus (BDTT) who achieved a complete response to Dur/Tre therapy. The BDTT progressed to the bifurcation of the left and right hepatic ducts. Over time, both the tumors and BDTT progressively decreased in size, and a complete response was confirmed using the Response Evaluation Criteria in Solid Tumors (version 1.1.) 6 months after treatment administration. Subsequently, immune-related adverse events, including type 1 diabetes mellitus and diabetic ketoacidosis, emerged, leading to treatment discontinuation. The patient was undergoing outpatient follow-up in a drug-free state with no signs of recurrence 290 days after the initial administration of Dur/Tre. Although long-term and meticulous observations are required, the present findings could influence the choice of systemic chemotherapy for advanced HCC.

Progression After Molecular Targeted Agents: Hepatic Arterial Changes and Transarterial Chemoembolization in Hepatocellular Carcinoma

BACKGROUND/AIM

The purpose of this study was to determine changes in the hepatic arteries after treatment with a molecular targeted agent (MTA), and evaluate the safety and efficacy of transarterial chemoembolization (TACE) as a post-MTA treatment in patients with hepatocellular carcinoma (HCC).

PATIENTS AND METHODS

The cases of 33 patients with intermediate HCC treated with MTA and TACE were studied retrospectively. The hepatic arteries, and the safety and efficacy of TACE were evaluated before and after MTA treatment.

RESULTS

Following long-term MTA treatment, the diameters of hepatic arteries decreased significantly, while there was no difference in the diameters of the splenic artery or the portal vein. No significant adverse events were observed due to TACE after MTA; however, the therapeutic effect of TACE was limited after MTA treatment.

CONCLUSION

This study demonstrated that the diameters of hepatic arteries were significantly smaller than those before MTA induction, suggesting ischemic effects and tumor vessel "normalization" by MTA treatment. Although TACE can be performed as a post-MTA treatment without lowering the hepatic reserve or causing serious complications, its therapeutic effect is limited.
