Percutaneous radiofrequency ablation of tumor feeding artery before target tumor ablation may reduce local tumor progression in hepatocellular carcinoma

摘要

BackgroundLocal tumor progression (LTP) in early-stage hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) remains high. Tumor feeding artery ablation (FAA) before target tumor ablation was reported to reduce LTP in patients with HCC >3 cm. The aim of our study is to investigate whether FAA before target tumor ablation may reduce LTP in HCC <3 cm.
