Arterially directed therapies for hepatocellular carcinoma

Area of Science:

• Interventional Radiology
• Hepatobiliary Oncology

Background:

• Arterially directed therapies are crucial for hepatocellular carcinoma (HCC) patients ineligible for surgery or ablation.
• These treatments serve as a bridge to or facilitate down-staging for liver transplantation.
• Existing evidence suggests these therapies improve overall survival compared to supportive care alone.

Purpose of the Study:

• To review the current landscape of arterially directed therapies for HCC.
• To discuss patient selection, procedural techniques, safety profiles, and clinical outcomes.
• To highlight imaging findings associated with these locoregional treatments.

Main Methods:

• Review of established arterially directed therapies including chemoembolization, particle embolization, drug-eluting beads, and radioembolization.
• Discussion of patient selection criteria for optimal treatment benefit.
• Analysis of safety, efficacy, and imaging surveillance.

Main Results:

• Chemoembolization, particle embolization, drug-eluting beads, and radioembolization are effective for locoregional HCC control.
• These therapies demonstrate potential for prolonging overall survival in selected HCC patients.
• The review details techniques, safety considerations, and clinical outcomes.

Conclusions:

• Arterially directed therapies provide valuable options for HCC management beyond surgical or ablative interventions.
• These methods are integral for locoregional control and improving outcomes in patients awaiting or unsuitable for transplantation.
• A comprehensive understanding of techniques, safety, and imaging is essential for successful application.
