Abstract We read with great interest the article by Dr. Lee et al. [1], which compared the long-term outcomes of patients with perivascular hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA) and surgical resection (SR) as first-line treatment. By using propensity score matching (PSM) analyses, the authors concluded that SR provided better long-term tumor control and overall survival than RFA for patients with small periportal tumors. Herein, we would like to raise the following comments.
