Table 1 Scheme for the systematic assessment of histological features in liver cell nodules in cirrhotic livers

Feature	Modality of assessment
Nodule maximum diameter			Measurement in millimeter
Solitary arterioles			Average of individual arteries ×100 (medium power field, MPF) fields
Mitotic activity			Number of mitoses per 10 ×400 (10 high power fields, 10 HPF) fields
Trabecular thickness			Number of liver cells forming trabecular (LCT) width
Vascular invasion					Present/absent
Capsular invasion					Present/absent
Necrosis²				Present/absent
Nodule heterogeneity¹				Present/absent
Reticulin loss³	None	Grade 1	Grade 2	Grade 3	Grade 4	Grade 5
Capillarization (CD34)³	None	Grade 1	Grade 2	Grade 3	Grade 4	Grade 5
Cellular atypia³	None	Grade 1	Grade 2	Grade 3	Grade 4	Grade 5

¹Phenotypically recognizable “clonal” changes e.g. clear cell change, fatty change, microacinar structures;

²excluding post-treatment necrosis;
