Background: In most guidelines, no other interventional therapy but liver transplantation is recommended for the treatment of hepatocellular carcinoma (HCC) with Child-Pugh C cirrhosis (CP-C). However, in Japan, patients were sometimes treated with expectation of benefit. Summary: A workshop was conducted to explore the state of treatments for CP-C HCC in Japan. After the workshop, a questionnaire on therapies was given to the panelists. Clinical data of 769 patients with CP-C HCC from 8 hospitals as well as analyses of data collected by the Liver Cancer Study Group of Japan (LCSGJ) consisting of 1,344 CP-C HCC cases were presented. Patients who underwent liver transplantation were excluded. In total, 424 out of the 769 patients (55.1%) from the 8 hospitals and 537 out of 828 CP-C HCC cases (64.8%) from the LCSGJ data received interventional therapies, such as local ablation and transcatheter arterial chemoembolization. All panelists agreed that there was a subgroup of CP-C patients who benefitted from the locoregional therapies. The major goals for the therapies were to prevent HCC rupture and avoid obstruction of major vessels by tumor growth, which can lead to a sudden deterioration of the patients' condition. Patient liver function and tumor stage are both important factors for the decision to undergo treatment; however, the inclusion criteria for the treatments varied among the centers. Key Message: There exists a subgroup of CP-C patients who benefit from interventions for HCC.

A 72-year-old woman with advanced lung cancer had received systemic chemotherapy including atezolizumab. About three months after the initial administration of atezolizumab, her liver enzyme levels increased. The histopathological findings of the initial liver biopsy revealed acute inflammatory infiltrate, predominantly CD3 + , CD4 + and CD8 + T lymphocytes, in the hepatic lobules. We diagnosed her with atezolizumab-induced immune-related acute hepatitis. Oral corticosteroid therapy successfully improved the elevation of serum aminotransferases. A sequential liver biopsy demonstrated the rapid progression of liver fibrosis. Because hepatocellular carcinoma occurs most often in advanced cases of chronic liver disease, we should pay close attention to immune-related acute hepatic injury when treating patients with advanced liver diseases using atezolizumab.

Background & Aims Hepatitis C virus (HCV) infection has been known to cause various extrahepatic autoimmune disorders. The prevalence of platelet‐associated immunoglobulin G (PA‐IgG) has been high in patients with HCV infection. Because thrombocytopenia in HCV‐related liver diseases is a notable problem, we performed prospective study on the effect of direct‐acting antivirals (DAAs) treatment on PA‐IgG and platelet count. Methods A total of 215 patients with HCV‐related liver disease were enrolled in this study. The patients who discontinued DAAs or did not undergo adequate laboratory examinations and who did not achieve sustained virologic response were excluded and finally a total of 187 patients were investigated. Results A total of 171 patients (91.4%) were PA‐IgG positive (>46 ng/107 cells) before starting DAAs (baseline). The PA‐IgG level elevation was significantly correlated with higher liver inflammation and fibrosis markers (P < 0.05) and lower platelet count (P = 0.000019). The platelet count of the patients with low PA‐IgG titer tended to be higher at baseline, end of treatment (EOT), and at 12 and 24 weeks after EOT. The platelet count increased at EOT (P < 0.05) and 24 weeks after EOT (P < 0.01). The PA‐IgG levels were significantly decreased at EOT, 12 and 24 weeks after EOT (P < 0.01). Multiple regression analysis found that only platelet count at baseline was closely associated with negative conversion of PA‐IgG at 24 weeks after EOT (P = 0.004). Conclusions Eradication of HCV by DAAs treatment successfully decreased PA‐IgG level and increased platelet count.

Zinc is an essential trace element and plays critical roles in cellular integrity and biological functions. Excess copper induced both oxidative stress and endoplasmic reticulum (ER) stress in liver-derived cultured cells. Excess copper also induced impairment of autophagic flux at the step of autophagosome–lysosome fusion, as well as Mallory–Denk body (MDB)-like inclusion body formation. Zinc ameliorated excess copper-induced impairment of autophagic flux and MDB-like inclusion body formation via the maintenance of ER homeostasis. Furthermore, zinc also ameliorated free fatty acid-induced impairment of autophagic flux. These results indicate that zinc may be able to protect hepatocytes from various ER stress-related conditions.
