[Chemoembolization of malignant liver tumors]

Area of Science:

• Interventional Radiology
• Oncology
• Hepatology

Background:

• Hepatic tumors, including metastases and hepatocellular carcinoma, present significant treatment challenges.
• Hepatic chemoembolization is an interventional radiology technique used for liver tumor treatment.

Purpose of the Study:

• To describe the principles, drugs, vectors, techniques, and contraindications of hepatic chemoembolization.
• To review the efficacy of hepatic chemoembolization for malignant hepatic tumors, particularly hepatocellular carcinoma and endocrine tumor metastases.

Main Methods:

• Literature review of hepatic chemoembolization principles and techniques.
• Analysis of personal experience and published data, including controlled studies, on chemoembolization outcomes.
• Focus on results for endocrine tumor metastases and hepatocellular carcinoma.

Main Results:

• Encouraging results reported for metastases from endocrine tumors and hepatocellular carcinoma.
• Japanese authors and personal series show favorable outcomes in hepatocellular carcinoma.
• Chemoembolization can achieve partial or complete responses in malignant hepatic tumors.

Conclusions:

• Hepatic chemoembolization demonstrates potential for treating specific liver tumors.
• Patient selection criteria for optimal outcomes, especially in hepatocellular carcinoma with underlying liver disease, require further definition.
• Hepatic chemoembolization is considered an evolving technique for malignant hepatic tumors requiring continued evaluation.
