Figure 7.

The DFS and OS in similar-stage HCC (≤ 3 tumors each ≤ 3 cm in diameter) patients receiving SR or RFA in the validation set. (A) Patients undergoing SR had a better DFS than high-risk patients receiving RFA (p=0.0473). (B) The DFS was similar between the low-risk RFA and SR groups (p=0.141). (C) SR patients had a better OS than high-risk RFA patients (p=0.0148). (D) The OS was similar between the low-risk RFA and SR groups (p=0.625). DFS: disease-free survival, OS: overall survival, HCC: hepatocellular carcinoma, SR: surgical resection, RFA: radiofrequency ablation
