Figure 2 Survival curves according to the stage classifications of the 7^th edition tumor-node-metastasis staging system. A: Comparison of survival curves according to the stage classifications of the 7^th edition TNM staging system; B: Comparison of the DFS rates between the HCC patients with AFP < 100 mg/dL and those with AFP ≥ 100 mg/dL in the subgroup of stage II or III HCC; C: Comparison of the DFS rates between the HCC patients with AFP < 100 mg/dL and those with AFP ≥ 100 mg/dL in the subgroup of stage I HCC. HCC: Hepatocellular carcinoma; DFS: Disease free survival; AFP: Alpha-fetoprotein; TNM: Tumor-node-metastasis.
