Aim It is a matter of debate whether hepatic resection (HR) or radiofrequency ablation (RFA) should be preferred for the treatment of patients with hepatocellular carcinoma (HCC). The aim of this study is to compare the long-term outcome between HR and RFA in patients with solitary small-sized HCC. Methods One hundred and eighty-three patients with solitary HCC of 3cm or less who underwent either HR (n=101) or RFA (n=82) as a first-line treatment were enrolled in this study. Their cumulative disease-free and overall survival and prognostic factors were compared. Results The disease-free and overall survival in the HR group were significantly better than those in the RFA group for HCC of 3cm or less; the 5-year disease-free and overall survival rates were 46.8% versus 23.9% and 87.5% versus 59.4% (P=0.0008, =0.0002), respectively. In the subgroup analysis, the disease-free and overall survival in the HR group were significantly better than those in the RFA group for HCC of more than 2cm (P<0.0001, <0.0001, respectively), whereas there were no significant differences between the two groups for HCC of 2cm or less. In patients treated with RFA, a tumor size of more than 2cm was the only independent prognostic factor for disease-free survival (risk ratio=1.832, P=0.039). Conclusion HR is proposed as the first-line treatment for patients with solitary small-sized HCC rather than RFA, especially for those with tumors in the range 2-3cm.
