Hepatocellular carcinoma (HCC) is a cytotoxic chemotherapy-resistant tumor and most HCCs arise in a background of liver cirrhosis of various causes. Although the IMBrave150 trial showed remarkable advancements in the treatment of unresectable HCC with atezolizumab plus bevacizumab (AteBeva), therapeutic outcomes were unsatisfactory in more than half of the patients. Accordingly, many ongoing trials combine conventional modalities with new drugs such as immune checkpoint inhibitors for better treatment outcomes, and they are expected to benefit patients with limited responses to conventional treatment. Here, two patients with advanced stage HCC with preserved liver function and good performance status showed partial response after treatment with combination or sequential therapy of AteBeva, hepatic arterial infusion chemotherapy, radiation therapy, and transarterial chemoembolization. These findings indicate the efficacy of multidisciplinary treatment against advanced HCC. Additional studies are required to establish optimal treatment strategies.

Background/Aim
s: Lenvatinib was recently proven to be non-inferior to sorafenib in treating unresectable hepatocellular carcinoma (HCC) in a phase-3 randomized controlled trial. In this study, we investigated whether the response to lenvatinib was affected by tumor immunogenicity.
Methods
Between May 2019 and April 2020, nine patients with intermediate-to-advanced HCC, who were treated with lenvatinib after liver biopsy, were enrolled. Immunohistochemical staining and multi-color flow cytometry were performed on specimens obtained from liver biopsy.
Results
Among the nine patients enrolled, four showed objective responses (complete responses+partial responses). Immunohistochemical staining for CD3, CD68, and programmed cell death ligand 1 (PD-L1) demonstrated that patients with objective responses showed marked infiltration of T cells and PD-L1-expressing macrophages in intra-tumoral and peri-tumoral tissues compared to those without objective responses. A significant difference in the numbers of infiltrated T cells, both in the intra-tumoral (P<0.01) and peri-tumoral regions (P<0.05), were identified between responders and non-responders. Regarding the number of infiltrated macrophages, no significant difference was found between the responders and non-responders, although the number of PD-L1-expressing tumor-associated macrophages was significantly higher in responders than that in non-responders (P<0.05).
Conclusions
Tumor immunogenicity, as indicated by T cell and PD-L1-positive macrophage infiltration, affects lenvatinib response in unresectable HCC.

Abstract PDF: Although post-transplantation lymphoproliferative disease (PTLD) after liver transplantation is very rare, its prognosis is worse than that of PTLD following other types of solid organ transplantation. Here, we report a rare case of early onset polymorphic PTLD in a graft liver occurring five months after deceased-donor liver transplantation due to hepatocellular carcinoma and hepatitis C virus infection. Initially, findings from contrast-enhanced magnetic resonance imaging mistakenly suspected the lesion was a necrotizing abscess with central necrosis. However, ¹⁸F-fluorodeoxyglucose positron emission tomography and biopsy findings confirmed an Epstein-Barr virus (EBV)-associated, B cell type polymorphic PTLD with central necrosis. Our case suggests regular monitoring of EBV serologic status for liver transplant recipients who were initially in an EBV seronegative state. Although early-onset PTLD is very rare after liver transplantation, PTLD should be suspected when recipients show the seroconversion for EBV proteins and the development of new tumors with various clinical presentations.
