Figure describing the anatomical classification of portal vein tumor thrombosis as suggested by the Liver Cancer Study Group of Japan (LCSGJ).
HCC, Hepatocellular carcinoma; Vp0 = no PVTT; Vp1 = segmental PV invasion; Vp2 = right anterior or posterior PV; Vp3 = right or left PV; and Vp4 = main trunk and/or contra-lateral portal vein branch to the primarily involved lobe.

Flow diagram showing the reasons for patient exclusions, and the final number of patients included in the analysis.
HCC, Hepatocellular carcinoma; PVTT, Portal vein tumor thrombosis; AFP, Alpha-fetoprotein.

Kaplan-Meier curves comparing overall survival of patients undergoing different therapies.
TACE, Transarterial chemoembolization; SIRT, Selective internal radiation therapy; BSC, Best supportive care.

Median overall survival according to treatment modalities and PVTT stage (Vp1–Vp4).
Middle text field: Median OS; lower left corner: Number of patients; NA: Not available because n = 2. PVTT, Portal vein tumor thrombosis; TACE, Transarterial chemoembolization; SIRT, Selective internal radiation therapy; BSC Best supportive care.
