AIM: To investigate whether an ablative margin (AM)> 1.0 cm might reduce chance of
recurrence for patients with hepatocellular carcinoma (HCC) tumors 3.1 to 5.0 cm in size …

AIM: To investigate the treatment strategies and long-term outcomes of radiofrequency
ablation (RFA) of hepatocellular carcinoma (HCC) in difficult locations and to compare the …

Objective: The purpose of this study was to evaluate the risk factors for local recurrence with
radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) measuring≤ 2 cm …

Results The 5-year OS rate of the entire sample was 44.3%(95% confidence interval: 36.7–
55.8); Child–Pugh class B was the worst negative prognostic factor (hazard ratio: 2.06; P …

Background In our previous study, we classified the radicality (R grading) of percutaneous
radiofrequency ablation (RFA) therapy for single hepatocellular carcinoma (HCC) according …

Background In the present study we classified the radicality of percutaneous radiofrequency
thermal ablation (RFA) therapy according to the extent of the ablated margin. We measured …

Background Radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC) is ordinarily
indicated for those with three or fewer nodules, none of which exceeds 3 cm in diameter …

Purpose To compare retrospectively the effects of percutaneous radiofrequency (RF)
ablation with those of hepatic resection in the treatment of hepatocellular carcinoma (HCC) …

Background Despite the high complete necrosis rate of radiofrequency ablation (RFA),
tumor recurrence, either local tumor recurrence or new tumor formation, remains a …

AIM: To evaluate long-term outcomes of radiofrequency (RF) ablation as first-line therapy for
single hepatocellular carcinoma (HCC)≤ 3 cm and to determine survival and prognostic …
