Prognostic prediction across a gradient of total tumor volume in patients with hepatocellular carcinoma undergoing locoregional therapy

Table 5 Risk score assessment according to the original and total tumor volume (TTV)-based CLIP scoring system

Parameters	Original CLIP	TTV-based CLIP
Tumor morphology
Single and <50% liver span	0	-
Multiple and <50% liver span	1	-
≥ 50% liver span	2	-
Total tumor volume
<50 cm³	-	0
50-200 cm³	-	1
200-500 cm³	-	2
>500 cm³	-	3
Serum AFP level (ng/mL)
