Multiple imaging modality-guided radiofrequency ablation combined with transarterial chemoembolization for hepatocellular carcinoma in special locations.

Purpose: We aimed to evaluate the safety and effectiveness of radiofrequency ablation (RFA) combined with transarterial chemoembolization (TACE) guided by multiple imaging modalities for hepatocellular carcinomas (HCCs) in special (i.e., high-risk or unfavorable) locations compared with those in conventional locations.

Adjuvant percutaneous radiofrequency ablation of feeding artery of hepatocellular carcinoma before treatment.

Aim: To evaluate the feasibility and efficacy of percutaneous radiofrequency ablation (RFA) of the feeding artery of hepatocellular carcinoma (HCC) in reducing the blood-flow-induced heat-sink effect of RFA.

Methods: A total of 154 HCC patients with 177 pathologically confirmed hypervascular lesions participated in the study and were randomly assigned into two groups. Seventy-one patients with 75 HCCs (average tumor size, 4.

[Feasibility of improving radiofrequency ablation of hepatocellular carcinoma by percutaneously blocking tumor-feeding vessels].

Objective: To explore the feasibility and outcome of radiofrequency ablation (RFA) in blocking feeding vessels of hypervascular hepatocellular carcinoma (HCC).

Methods: Totally 101 patients pathologically confirmed hypervascular HCC were included in the study. In percutaneous arterial ablation (PAA) + RFA group, 71 patients with 74 HCC underwent PAA before classical RFA of the other regions of the tumors, while in the RFA group, another 83 patients with 102 HCC were treated with RFA directly.

Radiofrequency ablation of problematically located hepatocellular carcinoma: tailored approach.

Background: The challenge for radiofrequency ablation (RFA) of hepatocellular carcinomas (HCC) in problematic locations is that the outcome is limited due to insufficient ablation or injury of nearby structures. This study aimed to evaluate effective strategy and treatment results of RFA in these cases.

Methods: Ultrasound guided percutaneous RFA was performed in 326 HCC patients.
