Table 2 Barcelona Clinic Liver Cancer staging system for hepatocellular carcinoma

Stage of HCC	Tumor features	Child-Pugh classification	Performance status test	Treatment
Stage 0	Single < 2 cm carcinoma in situ	Child-Pugh A	0	Resection
Stage A	Single < 5 cm or 3 nodules < 3 cm	Child-Pugh A-B	0	Liver transplant, percutaneous ethanol injection, radiofrequency ablation
Stage B	Single > 5 cm or multi-nodular	Child-Pugh A-B	0	TACE
Stage C	Portal vein invasion	Child-Pugh A-B	1-2	Sorafenib
Stage D	Distant metastasis	Child-Pugh A-B	3-4	Symptomatic

HCC: Hepatocellular carcinoma; TACE: Transarterial chemoembolization.
