Sorafenib has been widely used to treat unresectable hepatocellular carcinoma (HCC) but most studies have been done in Child-Pugh A (CP-A) patients with well-preserved liver function. We evaluated the overall survival (OS) and tolerance to sorafenib in a large cohort of Child-Pugh B (CP-B) HCC patients as compared to CP-A HCC patients. We prospectively studied 130 patients with advanced HCC who started sorafenib between January 2011 and December 2015. Patients were classified as CP-A (n = 65) or CP-B (n = 65). The average OS for all 130 patients was 10 months. CP-A patients had a median survival rate significantly longer than CP-B patients: 12 months vs. 6 months. The OS found in our group of CP-B patients was 6.5 months, which is higher than that found in most studies done so far. When stratified, our CP-B patients had better OS than ever reported. The dose of the drug was interrupted due to adverse events (AEs) in 38 (29%) of the patients, of whom 20 (30%) were CP-A patients and 18 (28%) were CP-B patients. This real-life cohort of CP-B HCC patients treated with sorafenib had a higher survival than that described in the literature, with a satisfactory safety profile. Despite the high prevalence of severe AEs in CP-B patients, there were fewer treatment interruptions in this group, indicating that Child-Pugh B patients can tolerate treatment and may benefit from sorafenib.

Background We aimed to evaluate the safety, efficacy and prognostic impact of baseline and early clinical markers in both Child-Pugh A and B patients with advanced hepatocellular carcinoma (HCC). Methods We prospectively studied 89 Japanese patients with HCC (Child-Pugh A, n = 59; Child-Pugh B, n = 30) who were started with sorafenib between May 2010 and July 2013. Results Frequency of sorafenib-related adverse events was almost similar between Child-Pugh score 5, 6, and 7 patients. The rate of liver dysfunction, including any grade encephalopathy, ≥ grade 3 ascites, or ≥ grade 3 bilirubin increased, in Child-Pugh score ≥8 group was significantly higher than that in the other groups. The median overall survival of Child-Pugh score 5, 6, 7 and ≥8 patients were 14.5, 11.1, 8.7 and 4.6 months, respectively. Patients in Child-Pugh score 6 had significantly longer OS than those in Child-Pugh score 7 ( P = 0.049). Multivariate analysis identified macrovascular invasion (MVI), alpha-fetoprotein (AFP), Child-Pugh score and aspartate aminotransferase (AST) as baseline predictors of survival. However, extrahepatic metastasis (EHM) was not a significant prognostic factor. In addition, decrease in AFP level and development of hand-foot skin reaction within 4 weeks after sorafenib initiation were closely associated with favorable survival. Conclusion It is possible that not only Child-Pugh score 5 and 6 but also 7 patients are eligible for future clinical trials with sorafenib or similar drugs. Various survival predictors identified in this study might be considered as stratification factor. Although both MVI and EHM is a phenotype of advanced HCC, MVI should be discriminated from EHM because of the prognostic impact on survival in sorafenib-treated advanced HCC patients.
