The "Liver damage" classification proposed by the Liver Cancer Study Group of Japan and Child-Pugh classification are both useful classifications for hepatic function. However, the factors responsible for the difference between the two classifications have not been fully investigated. The medical records of 594 admissions of 220 patients with hepatocellular carcinoma (HCC) were retrospectively analyzed for encephalopathy, ascites, serum bilirubin and albumin, plasma retention rate (%) at 15min after injection of 0.5mg/kg of indocyanine green (ICG R15), and prothrombin time. Of 594 admissions, ICG R15 was tested in 337 (56.7%). The Child-Pugh classification was evaluated in all 594 admissions, but the "Liver damage" could be evaluated in 510 (85.9%) due to the lack of ICG R15 results. Of the 594 admissions, 372 (62.6%), 162 (27.3%), and 60 (10.1%) were Child-Pugh grade A, B, and C, respectively. Of the 510 admissions, 219 (42.9%), 202 (39.6%), and 89 (17.5%) were "Liver damage" grade A, B, and C, respectively. The grade of "Liver damage" was similar to that of Child-Pugh classification in 369 (72.4%), under-evaluated in 138 (27.1%), and over-evaluated in 3 (0.6%). The Child-Pugh classification was statistically a better classification for predicting outcome than "Liver damage", but the "Liver damage" had better stratification ability than Child-Pugh classification in patients with relatively good liver function. Although the "Liver damage" could not be evaluated in some cases due to the lack of ICG R15 results, this classification system is useful in the evaluation and prediction of outcome of patients with early-stage liver diseases.
