Hepatocellular Carcinoma with Hepatic Vein and Inferior Vena Cava Invasion

Area of Science:

• Hepatobiliary surgery
• Surgical oncology
• Gastroenterology

Background:

• Hepatocellular carcinoma (HCC) commonly invades intrahepatic vessels.
• Hepatic vein (HV) and inferior vena cava (IVC) involvement by HCC is infrequent.
• This invasion is associated with poor prognosis.

Purpose of the Study:

• To review the epidemiology of HCC with HV and IVC invasion.
• To outline the classification and clinical features of this condition.
• To discuss management strategies and outcomes for HCC invading the HV and IVC.

Main Methods:

• Literature review of studies on HCC with HV and IVC invasion.
• Synthesis of epidemiological data.
• Analysis of clinical presentations and management options.

Main Results:

• HCC invasion of HV and IVC is uncommon.
• Clinical features vary, often presenting late.
• Management strategies include surgical resection, transarterial chemoembolization, and systemic therapy.
• Survival rates are generally low but can be improved with aggressive treatment in selected cases.

Conclusions:

• HCC with HV and IVC invasion requires careful management.
• Aggressive treatment strategies can improve outcomes for select patients.
• Further research is needed to optimize treatment protocols.
