Controlled blocking of hepatic artery flow with enzymatically degradable microspheres combined with oncolytic drugs

Area of Science:

• Oncology
• Interventional Radiology
• Pharmacology

Background:

• Secondary liver neoplasms present a significant treatment challenge.
• Traditional therapies like hepatic artery ligation have limitations.
• Intra-arterial chemotherapy offers targeted drug delivery.

Purpose of the Study:

• To evaluate a new method for intermittent hepatic arterial flow arrest.
• To assess the efficacy and safety of combining this method with intra-arterial 5-fluorouracil (5-Fu) for liver neoplasms.
• To compare outcomes with established treatments.

Main Methods:

• A cohort of 12 patients with secondary liver neoplasms was treated.
• A new intermittent hepatic arterial flow arrest technique was employed.
• Polysaccharide microspheres and 5-fluorouracil (5-Fu) were infused intra-arterially via catheter.

Main Results:

• The treatment demonstrated no significant adverse side effects.
• Clinical effects were observed in the patient cohort.
• Overall survival rates were comparable to hepatic artery ligation.

Conclusions:

• Intermittent hepatic arterial flow arrest combined with intra-arterial 5-Fu is a safe and potentially effective treatment for secondary liver neoplasms.
• This approach offers an alternative with comparable outcomes to hepatic artery ligation.
• Further research may explore optimization and broader application.
