Hepatol Int 2021; 15:1421-1430. [PMID: 34741723 DOI: 10.1007/s12072-021-10263-x] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Accepted: 10/18/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUNDS ALT ≥ 80 U/L and HBV DNA ≥ 2000 IU/ml are treatment criteria of APASL guidelines for chronic hepatitis B (CHB) patients. The need of antiviral therapy for patients in gray zone (ALT < 80 U/L or HBV DNA < 2000 IU/ml) is controversial. This study aimed to develop a scoring system to predict hepatocellular carcinoma (HCC) and evaluate the benefit of antiviral therapy in these patients. METHODS Seven hundred and forty-nine patients were analyzed. Significant variables were weighted to develop a scoring system for HCC prediction. The area under receiver operating curves (AUROC) were estimated and validated by REVEAL-HBV cohort (n = 3527). RESULTS Older age (p < 0.001), male sex (p = 0.036), family history of HCC (p = 0.002) and HBV DNA ≥ 2000 IU/ml (p = 0.045) were independently associated with HCC. A 14-point risk score system predicts 3 and 5-years HCC risk to be 0.866 and 0.868 of AUROC, respectively in the derivation cohort; 0.821 and 0.820, in the REVEAL-HBV cohort. The cumulative HCC incidence was higher in the high risk (score ≥ 8) group both in derivation and validation cohorts (p < 0.001). Patients with antiviral therapy had lower HCC incidence compared to those without (p = 0.016). Of note, antiviral therapy significantly decreased HCC in the high risk group (p = 0.005), but not in the low risk group (p = 0.705). CONCLUSIONS A risk scoring system is established and validated. Of CHB patients in gray zone of APASL guidelines, those with risk scores ≥ 8 had higher risk of HCC, but the risk could be significantly reduced by antiviral therapy.

Abstract
BACKGROUND The coexistence of cirrhosis complicates the early detection of hepatocellular carcinoma (HCC). Thus, novel biomarkers for HCC early detection are needed urgently. Traditionally, HCC detection is carried out by evaluating alpha-fetoprotein (AFP) levels combined with imaging techniques. This work aimed to assess interleukin (IL-6) and insulin-like growth factor 2 (IGF 2) as possible HCC markers in comparison to AFP in patients with and without HCC. RESULTS ROC analysis showed that IGF2 had the highest area under the curve (AUC) for discriminating HCC from liver cirrhosis (0.86), followed by IL6 (0.82), AFP (0.72), and platelet count (0.6). A four-marker model was developed and discriminated HCC from liver cirrhosis with an AUC of 0.97. The best cut-off was 1.28, at which sensitivity and specificity were 90% and 85%, respectively. For small tumor (< 2 cm), the model had an AUC of 0.95 compared to AFP (0.72). Also, the model achieved perfect performance with AUC of 0.93, 0.94, and 0.95 for BCLC (0-A), CLIP (0-1), and Okuda (stage I), respectively, compared to AFP (AUC of 0.71, 0.69, and 0.67, respectively). CONCLUSIONS The four markers may serve as a diagnostic model for HCC early stages and help overcome AFP poor sensitivity.

Long-term follow-up of cumulative incidence of hepatocellular carcinoma in hepatitis B virus patients without antiviral therapy. World J Gastroenterol 2021; 27:1101-1116. [PMID: 33776376 PMCID: PMC7985729 DOI: 10.3748/wjg.v27.i11.1101] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2020] [Revised: 01/07/2021] [Accepted: 02/11/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND China has a high prevalence of hepatitis B virus (HBV), but most chronic hepatitis B (CHB) patients do not receive standardized antiviral therapy. There are few relevant reports addressing the outcomes of the large number of CHB patients who do not receive antiviral therapy.
AIM To observe the outcomes of long-term follow-up of patients with CHB without antiviral treatment.
METHODS This study included 362 patients with CHB and 96 with hepatitis B cirrhosis without antiviral treatment and with only liver protection and anti-inflammatory treatment from 1993 to 1998. The median follow-up times were 10 and 7 years, respectively. A total of 203 CHB and 129 hepatitis B cirrhosis patients receiving antiviral therapy were selected as the control groups. The median follow-up times were 8 and 7 years, respectively. Kaplan-Meier curves were used to analyze the cumulative incidence of hepatocellular carcinoma (HCC), and the Cox regression model was used to analyze the risk factors for HCC.
RESULTS Among the patients in the non-antiviral group, 16.9% had spontaneous decreases in HBV DNA to undetectable levels, and 32.8% showed hepatitis B e antigen (HBeAg) seroconversion. In the antiviral group, 87.2% of patients had undetectable HBV DNA, and 52% showed HBeAg seroconversion. Among CHB and hepatitis B cirrhosis patients, the cumulative incidence rates of HCC were 14.9% and 53.1%, respectively, in the non-antiviral group and were 10.7% and 31.9%, respectively, in the antiviral group. There was no difference between the two groups regarding the CHB patients (P = 0.842), but there was a difference between the groups regarding the hepatitis B cirrhosis patients (P = 0.026). The cumulative incidence rates of HCC were 1.6% and 22.3% (P = 0.022) in the groups with and without spontaneous HBeAg seroconversion, respectively. The incidence rates of HCC among patients with and without spontaneous declines in HBV DNA to undetectable levels were 1.6% and 19.1%, respectively (P = 0.051). There was no difference in the cumulative incidence of HCC between the two groups regarding the patients with drug-resistant CHB (P = 0.119), but there was a significant difference between the two groups regarding the patients with cirrhosis (P = 0.004). The Cox regression model was used for regression of the corrected REACH-B score, which showed that alanine aminotransferase > 400 U/L, history of diabetes, and family history of liver cancer were risk factors for HCC among men aged > 40 years (P < 0.05). Multifactorial analysis showed that a family history of HCC among men was a risk factor for HCC.
CONCLUSION Antiviral therapy and non-antiviral therapy with liver protection and anti-inflammatory therapy can reduce the risk of HCC. Antiviral therapy may mask the spontaneous serological response of some patients during CHB. Therefore, the effect of early antiviral therapy on reducing the incidence of HCC cannot be overestimated.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver malignancy resulting in high mortality. HCC progression is associated with abnormal signal transduction that changes cell signaling pathways and ultimately leads to dysregulation of cell functions and uncontrolled cell proliferation. Present study was undertaken with the objective to identify differentially expressed proteins and quantify their transcript expression in the liver of HCC-bearing rats vis-à-vis controls and to decipher the network involving interaction of genes coding for the characterized proteins to an insight into mechanism of HCC tumorigenesis. 2D-Electrophoresis and MALDI-TOF-MS/MS were used to characterize differentially expressed proteins in DEN (diethylnitrosamine)-induced HCC tissue using the protocol reported by us earlier. Real-time PCR was performed to quantify the expression of transcripts for the identified proteins. GENEMANIA, an interacting network of genes coding for selected proteins, was deciphered that provided the functional role of these proteins in HCC progression. Upregulation of proteins SYNE1, MMP10, and MTG1 was observed. The mRNA quantification revealed elevated expression of their transcripts at HCC initiation, progression, and tumor stages. Network analysis showed the involvement of the genes coding for these proteins in dysregulation of signaling pathways during HCC development. The elevated expression of SYNE1, MMP10, and MTG1 suggests the role of these proteins as potential players in HCC progression and tumorigenesis.

Abstract
Hepatocellular carcinoma (HCC) is the 5th most frequently diagnosed cancer in the world, according to the World Health Organization. The incidence of HCC is between 3/100000 and 78.1/100000, with a high incidence reported in areas with viral hepatitis B and hepatitis C, thus affecting Asia and Africa predominantly. Several international clinical guidelines address HCC diagnosis and are structured according to the geographical area involved. All of these clinical guidelines, however, share a foundation of diagnosis by ultrasound surveillance and contrast imaging techniques, particularly computed tomography, magnetic resonance imaging, and sometimes contrast-enhanced ultrasound. The primary objective of this review was to systematically summarize the recent published studies on the clinical utility of serum biomarkers in the early diagnosis of HCC and for the prognosis of this disease.

Biochim Biophys Acta Mol Basis Dis 2019; 1865:1113-1125. [PMID: 30779947 DOI: 10.1016/j.bbadis.2018.12.007] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2018] [Revised: 11/06/2018] [Accepted: 12/05/2018] [Indexed: 12/12/2022]
Abstract
Vasculogenic mimicry (VM) results in the formation of an alternative circulatory system that can improve the blood supply to multiple malignant tumors, including hepatocellular carcinoma (HCC). However, the potential mechanisms of RhoC/ROCK in VM have not yet been investigated in HCC. Here, RhoC expression was upregulated in HCC tissues, especially the VM-positive (VM+) group, compared to noncancerous tissues (P < 0.01), and patients with high expression of RhoC had shorter survival times (P < 0.001). The knockdown of RhoC via short hairpin RNA (shRNA) in SK-Hep-1 cells significantly decreased VM formation and cell motility. In contrast, cell motility and VM formation were remarkably enhanced when RhoC was overexpressed in HepG2 cells. To further assess the potential role of ROCK1 and ROCK2 on VM, we stably knocked down ROCK1 or ROCK2 in MHCC97H cells. Compared to ROCK1 shRNA, ROCK2 shRNA could largely affect VM formation, cell motility and the key VM factors, as well as the epithelial-mesenchymal transition (EMT) markers in vitro and in vivo. Moreover, p-ERK, p-MEK, p-FAK, p-paxillin, MT1-MMP and MMP2 levels were clearly altered following the overexpression of RhoC, but ROCK2 shRNA had little effect on the expression of p-FAK, which indicated that RhoC regulates FAK/paxillin signaling, but not through ROCK2. In conclusion, our results show that RhoC/ROCK2 may have a major effect on VM in HCC via ERK/MMPs signaling and might be a potential therapeutic target for the treatment of HCC.

Abstract
Staging of hepatocellular carcinoma (HCC) is necessary for guiding prognostication, management, and research purposes that further aid in the improvement of existing clinical and epidemiological health services. Though there are some new staging systems for HCC developed in different parts of the world, there is no globally accepted staging system that allows for comparison of current management protocols among heterogeneous populations. In this review, we discuss the evolution and applicability in clinical practice of different clinical staging systems of HCC-Okuda, CLIP (Cancer of the Liver Italian Program) score, MESIAH (Model to Estimate Survival In Ambulatory HCC patients) score, ITA.LI.CA (Italian Liver Cancer) score, BCLC (Barcelona Clinic Liver Cancer) staging, HKLC (Hong Kong Liver Cancer) staging, and the Alberta algorithm. This review aims to highlight the main criteria for assessing the prognosis of HCC that these different staging systems take into account, their strengths and limitations for use in modern clinical practice. Despite the limitations of the BCLC staging system, it remains the most validated and reliable system for prognostication. However, there is a need to update the BCLC staging system to include recent data on locoregional and systemic therapies for HCC, expanded criteria for transplantation, and systemic therapy for hepatitis C infection.

Abstract
Background Cyclin Y (CCNY) is a member of the cyclin family of proteins that regulate the cell cycle. The aims of this study were to compare the expression of CCNY in normal liver and human hepatocellular carcinoma (HCC), in normal and HCC cell lines, and in mouse HCC tumor xenografts. Material/Methods Tumor tissues from 55 patients diagnosed with HCC were studied for CCNY expression. Human HCC cell lines, SK-Hep1, HepG2, HEP3B, HuH7 and L02 were studied using the MTT cell proliferation assay, cell apoptosis, transwell and wound healing assays. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) and Western blot were used to measure CCNY expression. Indirect immunofluorescence was used to assess cell apoptosis. In vivo xenograft mouse model was constructed and examined histologically. Results Expression of CCNY in human HCC tumor tissues was significantly increased when compared with adjacent normal liver (all P<0.05). HCC cells grown in vitro showed significantly increased expression of CCNY, cell proliferation, and migration, and a reduced rate of apoptosis, compared with cells with CCNY knockdown (siRNA) (all P<0.05). In the xenograft mouse model, tumor volume and weight in the CCNY overexpression group were significantly increased, compared with CCNY knockdown (siRNA) group (all P<0.05). Conclusions In tissue samples of human HCC, and human HCC cell lines, increased expression of CCNY was significantly associated with cell proliferation and migration. Further studies are recommended to evaluate the role of CCNY as a potential diagnostic biomarker or target for treatment in human HCC.

Genes directly regulated by NF-κB in human hepatocellular carcinoma HepG2. Int J Biochem Cell Biol 2017; 89:157-170.

Abstract
It has been well-known that over activation of NF-κB has close relationship with hepatitis and hepatocellular carcinoma (HCC). However, the complete and exact underlying molecular pathways and mechanisms still remain not fully understood. By manipulating NF-κB activity with its recognized activator TNFα and using ChIP-seq and RNA-seq techniques, this study identified 699 NF-κB direct target genes (DTGs) in a widely used HCC cell line, HepG2, including 399 activated and 300 repressed genes. In these NF-κB DTGs, 216 genes (126 activated and 90 repressed genes) are among the current HCC gene signature. In comparison with NF-κB target genes identified in LPS-induced THP-1 and TNFα-induced HeLa cells, only limited numbers (24-46) of genes were shared by the two cell lines, indicating the HCC specificity of identified genes. Functional annotation revealed that NF-κB DTGs in HepG2 cell are mainly related with many typical NF-κB-related biological processes including immune system process, response to stress, response to stimulus, defense response, and cell death, and signaling pathways of MAPK, TNF, TGF-beta, Chemokine, NF-kappa B, and Toll-like receptor. Some NF-κB DTGs are also involved in Hepatitis C and B pathways. It was found that 82 NF-κB DTGs code secretory proteins, which include CCL2 and DKK1 that have already been used as HCC markers. Finally, the NF-κB DTGs were further confirmed by detecting the NF-κB binding and expression of 14 genes with ChIP-PCR and RT-PCR. This study thus provides a useful NF-κB DTG list for future studies of NF-κB-related molecular mechanisms and theranostic biomarkers of HCC.

Abstract
The advent of next generation sequencing (NGS) technologies has advanced our understanding of the intrinsic biology of different gastrointestinal (GI) tumor types. The use of novel, more efficient sequencing platforms has improved turnaround times of sequencing results. This is providing real time opportunities to put precision medicine to the test. A number of early phase clinical trials are testing targeted therapies in unique molecularly characterized subsets of patients (baskets). While basket studies are gaining momentum, treatment failures serve to remind us that shifting from a histology-driven to a histology-agnostic approach is unlikely to be a failure-free strategy for a number of tumor types as recently learnt from vemurafenib failure in BRAF mutated metastatic colorectal cancer (mCRC). GI malignancies are clinically and molecularly heterogeneous. Unfortunately, development of biomarkers of response to therapy as well as targeted therapies for GI adenocarcinomas has fallen behind compared to other malignancies. Trastuzumab is the only FDA approved targeted therapy for GI adenocarcinomas for which a biomarker of response (HER2 amplifications) is available. In addition, RAS mutations are known to predict lack of response to epidermal growth factor receptor (EGFR) inhibitors in advanced colorectal cancer (CRC) patients. However, NGS has recently revealed that a number of actionable genetic aberrations are present at low prevalence across different GI malignancies. Prospective randomized clinical trials will determine whether matching actionable aberration with targeted therapy will contribute to improve survival in patients with GI malignancies. Here, we review current evidence for targeted therapies in GI malignancies, as well as application and pitfalls of NGS including tissue testing and liquid biopsies.

Abstract
BACKGROUND The mitochondrial GTPase mitofusin-2 (MFN2) gene encodes a mitochondrial membrane protein that can induce apoptosis of hepatocellular carcinoma (HCC) via the mitochondrial apoptotic pathway, as validated in our previous research. However, little is known of the clinical significance of MFN2 expression and its signaling pathways in HCC. METHODS MFN2 mRNA expression in tumor and adjacent non-tumor tissues from 115 patients with HCC was investigated using quantitative real-time PCR. The association of the MFN2 mRNA expression level with clinical and pathological parameters was evaluated statistically, while a comparative microarray analysis was used to identify MFN2 signaling pathways in HepG2 cells. RESULTS MFN2 was significantly (p < 0.0001) downregulated in HCC tissues. Low MFN2 expression was significantly correlated with sex and preoperative alpha-fetoprotein (p < 0.05). Both a Kaplan-Meier survival curve and multivariate analyses showed that MFN2 was related to overall survival. A comparative gene expression microarray revealed 211 upregulated (58 %) and 153 downregulated (42 %) genes. Eighteen pathways were identified as the most significant pathways correlated with MFN2. CONCLUSIONS Low MFN2 expression in HCC indicated a worse overall survival. Crucial signaling molecules such as PI3K-AKT, cytokine receptor, and focal adhesion may participate in MFN2-mediated signaling pathway changes in HCC.

Abstract
Hepatocellular carcinoma (HCC) is the second cause of death due to malignancy in the world, following lung cancer. The geographic distribution of this disease accompanies its principal risk factors: Chronic hepatitis B virus and hepatitis C virus infection, alcoholism, aflatoxin B1 intoxication, liver cirrhosis, and some genetic attributes. Recently, type II diabetes has been shown to be a risk factor for HCC together with obesity and metabolic syndrome. Although the risk factors are quite well known and it is possible to diagnose HCC when the tumor is less than 1 cm diameter, it remains elusive at the beginning and treatment is often unsuccessful. Liver transplantation is thus far considered the best treatment for HCC as it cures HCC and the underlying liver disease. Using the Milan criteria, overall survival after liver transplantation for HCC is about 70% after 5 years. Many attempts have been made to go beyond the Milan Criteria and according to recent works reasonably good results have been achieved by using a histochemical marker such as cytokeratine 19 and the so-called "up to seven criteria" to divide patients into categories according to their risk of relapse. In addition to liver transplantation other therapies have been proposed such as resection, tumor ablation by different means, embolization and chemotherapy. An important step in the treatment of advanced HCC has been the introduction of sorafenib, the first oral, systemic drug that has provided significant improvement in survival. Treatment of HCC patients must be multidisciplinary and by using the different approaches discussed in this review it is possible to offer prolonged survival and quite good and sometimes even excellent quality of life to many patients.
