["Wrapping therapy" for hepatocellular carcinomas with collateral feeders]

Area of Science:

• Hepatobiliary Surgery
• Interventional Radiology
• Oncology

Background:

• Advanced hepatocellular carcinoma (HCC) often develops
• uncontrolled tumor growth and resistance to conventional therapies like chemoembolization.
• The emergence of collateral feeders from surrounding organs complicates treatment by bypassing targeted therapies.

Purpose of the Study:

• To evaluate the efficacy of a new treatment method, "wrapping therapy", for advanced HCC.
• To assess the impact of this therapy on patient survival rates.
• To determine the feasibility of using wrapping therapy in cases refractory to arterial therapies.

Main Methods:

• "Wrapping therapy" involved using silicone rubber sheeting to intercept collateral feeders to the liver tumors.
• The procedure was applied to 18 patients with advanced HCC.
• Patients subsequently received regional chemotherapy and/or chemoembolization.

Main Results:

• Chemoembolization had been ineffective in 17 of the 18 patients prior to wrapping therapy.
• Hepatic angiograms identified obvious collateral feeders in two-thirds of the patients.
• The 3- and 4-year survival rates following wrapping therapy were both 54%.

Conclusions:

• "Wrapping therapy" is a viable option for advanced HCC uncontrolled by arterial therapies.
• The technique effectively addresses tumor vascularization challenges posed by collateral feeders.
• This method offers a potential survival benefit for patients with complex HCC cases.
