Post-hepatectomy survival in advanced hepatocellular carcinoma with portal vein tumor thrombosis

Figure 1 Results in patients with portal vein tumor thrombosis. A: Surgical procedures for portal vein tumor thrombosis; B: Comparison of the disease free survival rates between patients with vp1-2 HCC and those with vp3-4 HCC; C: Comparison of the overall survival rates between patients with vp1-2 HCC and those with vp3-4 HCC; D: Comparison of the overall survival rates between patients who underwent only hepatectomy and those who underwent hepatectomy combined with preoperative transarterial chemoembolization in the subgroup of HCC patients with macroscopic portal vein tumor thrombosis (vp2-4). HCC: Hepatocellular carcinoma; DFS: Disease free survival; OS: Overall survival; TACE + HR: Hepatectomy combined with preoperative transarterial chemoembolization; HR: Hepatectomy; vp: Portal vein invasion.

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.
