Cancer is the first cause of death in developed countries and the second in developing countries. Concerning the most frequent worldwide-diagnosed cancer, primary liver cancer represents approximately 4% of all new cancer cases diagnosed globally. However, among primary liver cancer, hepatocellular carcinoma is by far the most common histological subtype. Notwithstanding the health promotion and disease prevention campaigns, more than half a million new hepatocellular carcinoma cases are reported yearly, being estimated to growth continuously until 2020. Taking this scenario under consideration and the fact that some aspects concerning hepatocellular carcinoma evolution and metastasize process are still unknown, animal models assume a crucial role to understand this disease. The animal models have also provided the opportunity to screen new therapeutic strategies. The present review was supported on research and review papers aiming the complexity and often neglected chemically induced animal models in hepatocarcinogenesis research. Despite the ongoing debate, chemically induced animal models, namely, mice and rat, can provide unique valuable information on the biotransformation mechanisms against xenobiotics and apprehend the deleterious effects on DNA and cell proteins leading to carcinogenic development. In addition, taking under consideration that no model achieves all hepatocellular carcinoma research purposes, criteria to define the “ ideal” animal model, depending on the researchers’ approach, are also discussed in this review.

AbstractLiver cancer is the fourth leading cause of cancer-related death. Hepatocellular carcinoma (HCC) is a primary liver cancer that results from chronic hepatitis caused by multiple predisposing factors such as viral infection, alcohol consumption, and non-alcoholic fatty liver disease. Accumulating studies have indicated that dysfunction of the gut epithelial barrier and hepatic translocation of gut microbes may be implicated in the pathogenesis of HCC. However, the translocated bacteria in HCC patients remains unclear. Here, we characterised tumour-associated microbiota in patients with liver cancer and focused on HCC. We observed that the number of amplicon sequence variants in tumour-associated microbiota was significantly higher compared with that in non-tumour regions of the liver. The tumour-associated microbiota consisted of Bacteroidetes, Firmicutes, and Proteobacteria as the dominant phyla. We identified an unclassified genus that belonged to the Bacteroides, Romboutsia, uncultured bacterium of Lachnospiraceae as a signature taxon for primary liver cancer. Additionally, we identified Ruminococcus gnavus as a signature taxon for HCC patients infected with hepatitis B and/or hepatitis C viruses. This study suggests that tumour microbiota may contribute to the pathology of HCC.

Globally, liver cancer is the sixth most common cause of cancer mortality, with hepatocellular carcinoma (HCC) being the most common type of primary liver cancer. Emerging evidence states that diet is recognised as a potential lifestyle-related risk factor for the development of HCC. The aim of this systematic review is to determine whether there is an association between diet and the development of HCC. Using the PRISMA guidelines, three databases (MEDLINE Complete, CINAHL and Embase) were systematically searched, and studies published until July 2020 were included. Thirty observational studies were selected. The protocol was registered with PROSPERO (CRD42019135240). Higher adherence to the Mediterranean dietary pattern, Alternative Healthy Eating Index-2010, the Urban Prudent Dietary Pattern, the Traditional Cantonese Dietary Pattern, intake of vegetables, wholegrains, fish, poultry, coffee, macronutrients such as monounsaturated fats and micronutrients such as vitamin E, vitamin B9, β-carotene, manganese and potassium were associated with a reduced risk of HCC. The results suggest a potential role of diet in the development of HCC. Further quantitative research needs to be undertaken within a range of populations to investigate diet and the relationship with HCC risk.

Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer, followed by cholangiocarcinoma (CCA). HCC is the third most common cause of cancer death worldwide, and its incidence is rising, associated with an increased prevalence of obesity and nonalcoholic fatty liver disease (NAFLD). However, current treatment options are limited. Genetic factors and epigenetic factors, influenced by age and environment, significantly impact the initiation and progression of NAFLD-related HCC. In addition, both transcriptional factors and post-transcriptional modification are critically important for the development of HCC in the fatty liver under inflammatory and fibrotic conditions. The early diagnosis of liver cancer predicts curative treatment and longer survival. However, clinical HCC cases are commonly found in a very late stage due to the asymptomatic nature of the early stage of NAFLD-related HCC. The development of diagnostic methods and novel biomarkers, as well as the combined evaluation algorithm and artificial intelligence, support the early and precise diagnosis of NAFLD-related HCC, and timely monitoring during its progression. Treatment options for HCC and NAFLD-related HCC include immunotherapy, CAR T cell therapy, peptide treatment, bariatric surgery, anti-fibrotic treatment, and so on. Overall, the incidence of NAFLD-related HCC is increasing, and a better understanding of the underlying mechanism implicated in the progression of NAFLD-related HCC is essential for improving treatment and prognosis.

BackgroundImmune checkpoint inhibitors (ICIs) have revolutionized the landscape of PLC management at all evolutionary stages.1 As an anti-programmed cell death-1 (PD-1) antibody, camrelizumab monotherapy and in combination with apatinib, an anti-angiogenetic tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-2, chemotherapy or locoregional therapy, have demonstrated their efficacy in advanced hepatocellular carcinoma (HCC).2 3 4 5MethodsThis prospective, open-label, multi-center, observational RWS was conducted to evaluate efficacy and safety of camrelizumab in treatment of PLC in clinical practice. Eligible patients were histopathologically or cytologically identified HCC or intrahepatic cholangiocarcinoma, who were going to receive camrelizumab treatment, with age ≥18 ages, Eastern Cooperative Oncology Group performance status (ECOG PS) score of 0–2 and Child-Pugh score ≤ 9. Patients were treated at clinician discretion. Three hundred patients were planned to enroll, including advanced or peri-operative PLC. The primary endpoint was progress-free survival for advanced PLC, whose efficacy was available to analysis. Efficacy was assessed per Response Evaluation Criteria in Solid Tumors version 1.1.ResultsFrom March 29, 2020 to June 10, 2021,a total of 147 eligible patients of advanced PLC were enrolled and included in this interim analysis, with 128 (87.1%) men, 130 (94.9%) ECOG PS of 0–1, 139 (94.6%) HCC, 74 (50.4%) Barcelona Clinic Liver Cancer stage C, 98 (66.7%) Child-Pugh B, and 72 (49.0%) with extrahepatic metastases, shown in table 1. Of the 147 patients, 45 (30.1%) patients were treated with camrelizumab monotherapy, 79 (53.8%) patients with combination with angiogenesis inhibitors, of which 55 (37.4%) in combination with apatinib, 21 (14.3%) patients with camrelizumab and chemotherapy. Patients, who had at least one efficacy assessment, were included in the efficacy analyses. Up to July 19, 2021, with a median follow time of 6.2 months, 132 patients were available for efficacy analyses. Patient disposition was shown in figure 1. Objective response rate (ORR) and disease control rate (DCR) were 10%/30.8%/35.3% and 75.0%/86.5%/70.6% in camrelizumab monotherapy/combined with apatinib/combined with chemotherapy, respectively. (table 2) The most common camrelizumab-treatment related adverse events (AEs) included reactive cutaneous capillary endothelial proliferation (RCCEP) (12, 8.2%), ICI-induced pneumonia (2, 1.4%), enterocolitis (2, 1.4%), and nephritis (1, 0.7%), of which all these AEs recovered. Other AEs included increase of transaminase (5, 3.4%) and hypertension (4, 2.7%). All AEs were 1–2 grade and no treatment-related death occurred.Abstract 452 Table 1Baseline characteristicsAbstract 452 Figure 1Patient dispositionAbstract 452 Table 2Confirmed tumor response assessed by investigators per RECIST v1.1ConclusionsCamrelizumab, combined with anti-angiogenetic agents or chemotherapy, or monotherapy, demonstrated good efficacy and safety in treatment of PLC.Trial RegistrationChiCTR2000034264ReferencesLlovet JM, Kelley RK, Villanueva A, et al.

Animal models have become increasingly important in the study of hepatocellular carcinoma (HCC), as they serve as a critical bridge between laboratory-based discoveries and human clinical trials. Developing an ideal animal model for translational use is challenging, as the perfect model must be able to reproduce human disease genetically, anatomically, physiologically, and pathologically. This brief review provides an overview of the animal models currently available for translational liver cancer research, including rodent, rabbit, non-human primate, and pig models, with a focus on their respective benefits and shortcomings. While small animal models offer a solid starting point for investigation, large animal HCC models are becoming increasingly important for translation of preclinical results to clinical practice.

Hepatocellular carcinoma, one of the most dreaded complications of cirrhosis, is a frequent cancer with high mortality. Early primary liver cancer can be treated by surgery or ablation techniques, but advanced hepatocellular carcinoma remains a challenge for clinicians. Most of these patients have underlying cirrhosis, which complicates or even precludes treatment. Therefore, efficacious treatments without major side effects are welcomed. Initial results of treatment of advanced hepatocellular carcinoma with somatostatin analogues were promising, but subsequent trials have resulted in conflicting outcomes. This might be explained by different patient populations, differences in dosage and type of treatment and differences in somatostatin receptor expression in the tumor or surrounding tissue. It has been shown that the expression of somatostatin receptors in the tumor might be of importance to select patients who could benefit from treatment with somatostatin analogues. Moreover, somatostatin receptor expression in hepatocellular carcinoma has been shown to correlate with recurrence, prognosis, and survival. In this review, we will summarize the available data on treatment of primary liver cancer with somatostatin analogues and analyze the current knowledge of somatostatin receptor expression in hepatocellular carcinoma and its possible clinical impact.
