Abstract
Liver resection is widely considered the mainstay of curative therapy for small hepatocellular carcinoma (HCC). Radiofrequency ablation (RFA) was initially developed as a treatment for small HCC in patients with considerable cirrhosis and inadequate liver function reserve for liver resection. However, in some centers, RFA is now used for small HCC, as an alternative to liver resection or even as the preferred treatment. This Practice Point commentary discusses the findings and limitations of a retrospective cohort study by Livraghi et al. that analyzed the outcomes of a group of patients with small, single HCC who underwent treatment with RFA. The authors reported a low major complication rate and a local complete response rate similar to that after resection. This commentary highlights the issues to consider when interpreting and generalizing these results, in particular that these findings need to be interpreted in the light of studies that suggest a high rate of local recurrence and incomplete histopathological response after RFA of small HCC.
