Image-guided treatment for liver cancer

Area of Science:

• Interventional Radiology
• Hepatobiliary Oncology

Background:

• Early-stage hepatocellular carcinoma (HCC) frequently lacks symptoms, resulting in diagnosis at advanced stages.
• HCC exhibits resistance to chemotherapy and limited response to external beam radiation therapy.
• While surgical resection and liver transplantation offer curative potential, most patients present with unresectable disease.

Purpose of the Study:

• To discuss less invasive image-guided ablative and embolization therapies for hepatocellular carcinoma.
• To highlight the role of these therapies in palliating symptoms and potentially increasing survival.
• To inform radiologic technologists about procedural techniques and relevant anatomy for therapeutic agent delivery.

Main Methods:

• Review of image-guided ablative therapies (e.g., radiofrequency ablation, microwave ablation).
• Discussion of embolization techniques (e.g., transarterial chemoembolization, transarterial radioembolization).
• Emphasis on the importance of understanding patient anatomy for successful treatment delivery.

Main Results:

• Image-guided therapies offer less invasive treatment options for HCC.
• These procedures can provide symptom palliation and contribute to improved patient survival.
• Successful application requires knowledge of procedural techniques and patient-specific anatomy.

Conclusions:

• Less invasive image-guided therapies are crucial for managing unresectable hepatocellular carcinoma.
• Radiologic technologists play a vital role in the effective delivery of these treatments.
• Continued education on interventional techniques and anatomy is essential for optimizing patient outcomes in HCC management.
