Downstaging strategies for unresectable hepatocellular carcinoma

A significant number of patients with hepatocellular carcinoma(HCC)are usually diagnosed in advanced stages,that leads to inability to achieve cure.Palliative options are focusing on downstaging a locally advanced disease.It is wellsupported in the literature that patients with HCC who undergo successful conversion therapy followed by curative-intent surgery may achieve a significant survival benefit compared to those who receive chemotherapy alone or those who are successfully downstaged with conversion therapy but not treated with surgery.Hepatic artery infusion chemotherapy can be a potential downstaging strategy,since recent studies have demonstrated excellent outcomes in patients with colorectal liver metastatic disease as well as primary liver malignancies.

Combined hepatocellular cholangiocarcinoma: A clinicopathological update

Combined hepatocellular-cholangiocarcinoma(cHCC-CCA)is a rare primary liver cancer associated with an appalling prognosis.The diagnosis and manage-ment of this entity have been challenging to physicians,radiologists,surgeons,pathologists,and oncologists alike.The diagnostic and prognostic value of biomarkers such as the immunohistochemical expression of nestin,a progenitor cell marker,have been explored recently.With a better understanding of biology and the clinical course of cHCC-CCA,newer treatment modalities like immune checkpoint inhibitors are being tried to improve the survival of patients with this rare disease.In this review,we give an account of the recent developments in the pathology,diagnostic approach,and management of cHCC-CCA.

A review of the literature on the use of CRISPR/Cas9 gene therapy to treat hepatocellular carcinoma

Noncoding RNAs instruct the Cas9 nuclease to site speifillyl cleave DNA in the CRISPR/Cas9 system.Despite the high incidence of hepatocellular carcinoma(HCC),the patient's outcome is poor.As a result of the emergence of therapeutic resistance in HCC patients,dlinicians have faced difficulties in treating such tumor.In addition,CRISPR/Cas9 screens were used to identify genes that improve the dlinical response of HCC patients.It is the objective of this article to summarize the current understanding of the use of the CRISPR/Cas9 system for the treatment of cancer,with a particular emphasis on HCC as part of the current state of knowledge.Thus,in order to locate recent developments in oncology research,we examined both the Scopus database and the PubMed database.The ability to selectively interfere with gene expression in combinatorial CRISPR/Cas9 screening can lead to the discovery of new effective HCC treatment regimens by combining clinically approved drugs.Drug resistance can be overcome with the help of the CRISPR/Cas9 system.HCC signature genes and resistance to treatment have been uncovered by genome-scale CRISPR activation screening although this method is not without limitations.It has been extensively examined whether CRISPR can be used as a tool for disease research and gene therapy.CRISPR and its applications to tumor research,particularly in HCC,are examined in this study through a review of the literature.

Liver transplantation and resection in patients with hepatocellular cancer and portal vein tumor thrombosis: Feasible and effective?

Patients with locally advanced hepatocellular cancer(HCC)and portal vein tumor thrombosis(PVTT)have a dismal prognosis since limited treatment options are available for them.In recent years,effective systemic therapy,and advances in the understanding of technicalities and effectiveness of ablative therapies especially radiotherapy,have given some hope to prolong survival in them.This review summarized recent evidence in literature regarding the possible role of liver resection(LR)and liver transplantation(LT)in patients with locally advanced HCC and PVTT with no extrahepatic disease.Downstaging therapies have helped make curative resection or LT a reality in selected patients.This review emphasizes on the key points to focus on when considering surgery in these patients,who are usually relegated to palliative systemic therapy alone.Meticulous patient selection based on tumor biology,documented downstaging based on imaging and decrease in tumor marker levels,and an adequate waiting period to demonstrate stable disease,may help obtain satisfactory long-term outcomes post LR or LT in an intention to treat strategy in patients with HCC and PVTT.

Post-fontan circulation hepatocellular carcinoma:Open and laparoscopic hepatectomy

To the Editor:Fontan-associated liver disease shows increasing incidence as advances in pediatric cardiology have prolonged life expectancy in patients with single ventricle congenital heart defects[1].Their unique physiology and procedure-related sequelae present an increasingly relevant challenge in hepatic surgery.We hereby reported a series of patients suffering from hepatocellular carcinoma(HCC)who successfully underwent open and laparoscopic hepatectomy.

3-Epi-betulinic acid 3-O-β-D-glucopyranoside(eBAG)induces autophagy by activation of AMP-activated protein kinase in hepatocellular carcinoma

3-Epi-betulinic acid 3-O-β-D-glucopyranoside(eBAG)is a pentacyclic triterpene mainly distributed in food and medicinal plants,which exhibits various pharmacological properties.However,whether these functions are attributed to eBAG or additional components in these plants remain unknown.Herein,we report that eBAG exerted an inhibitory activity against hepatocellular carcinoma and esophageal cancer cells.EBAG induced non-apoptotic cell death in hepatocellular carcinoma cells.The eBAG-induced cell death was inhibited by knock-down of autophagy related gene(ATG)5 and ATG7,by administration of 3-methyladenine,a selective autophagy inhibitor that suppresses phosphoinositide 3-kinase(PI3K),and by chloroquine,a classic autophagy flux inhibitor.We demonstrated that eBAG induced an autophagy-mediated cell death.Application of eBAG mimicked cellular bioenergetics depletion leading to the reduction of intracellular ATP,activation of AMP-activated protein kinase(AMPK),and inhibition of mTOR.Co-treatment with compound C,an AMPK inhibitor,abrogated cell death induced by eBAG.We further validated the anti-tumor effect of eBAG in the murine xenograft model of hepatocellular carcinoma and found that eBAG treatment promoted the induction of autophagy and reduction of tumor growth in mice.As a functional food ingredient,eBAG is a potential therapeutic agent for the treatment of hepatocellular carcinoma and esophageal cancer.

Investigation of the feasibility of NRAV as a biomarker for hepatocellular carcinoma

The long non-coding RNA,Negative Regulator of Antiviral Response(NRAV)has been identified as a participant in both respiratory virus replication and immune checkpoints,however,its involvement in pan-cancer immune regulation and prognosis,particularly those of hepatocellular carcinoma(HCC),remains unclear.To address this knowledge gap,we analyzed expression profiles obtained from The Cancer Genome Atlas(TCGA)database,comparing normal and malignant tumor tissues.We found that NRAV expression is significantly upregulated in tumor tissues compared to adjacent nontumor tissues.Kaplan-Meier(K-M)analysis revealed the prognostic power of NRAV,wherein overexpression was significantly linked to reduced overall survival in a diverse range of tumor patients.Furthermore,noteworthy associations were observed between NRAV,immune checkpoints,immune cell infiltration,genes related to autophagy,epithelial-mesenchymal transition(EMT),pyroptosis,tumor mutational burden(TMB),and microsatellite instability(MSI)across different cancer types,including HCC.Moreover,NRAV upregulation expression was associated with multiple pathological stages by clinical observations.Furthermore,our investigation revealed a substantial elevation in the expression of NRAV in both HCC tumor tissues and cells compared to normal tissues and cells.The inhibition of NRAV resulted in the inhibition of cell proliferation,migration,and invasion in HCC cells,while also influencing the expression of CD274(PD-L1)and CD44,along with various biomarkers associated with EMT,autophagy,and pyroptosis.The aforementioned results propose NRAV as a promising prognostic biomarker for HCC.

Hepatocellular carcinoma-the role of the underlying liver disease in clinical practice

Hepatocellular carcinoma(HCC)is one of the most common causes of cancerrelated mortality.This particular type of cancer has the distinctive characteristic of mostly happening in individuals with an underlying liver disease.This makes the management of patients more challenging,since physicians must take into consideration two different conditions,the chronic liver disease and the tumor.The underlying liver disease has several implications in clinical practice,because different kinds of chronic liver disease can lead to varying degrees of risk of developing HCC,obstacles in surveillance,and differences in the efficacy of the treatment against HCC.A shift in the prevalence of liver diseases has been evident over the last few years,with viral hepatitis gradually losing the leading position as cause of HCC and metabolic dysfunction-associated steatotic liver disease gaining importance.Therefore,in an era of personalized medicine,it is imperative that physicians are aware of the underlying liver disease of individuals with HCC and its impact in the management of their tumors.

Influence of sex on outcomes of liver transplantation for hepatocellular carcinoma:a multicenter cohort study in China

Objective:Sex-specific differences are observed in various liver diseases,but the influence of sex on the outcomes of hepatocellular carcinoma(HCC)after liver transplantation(LT)remains to be determined.This study is the first Chinese nationwide investigation of the role of sex in post-LT outcomes in patients with HCC.Methods:Data for recipients with HCC registered in the China Liver Transplant Registry between January 2015 and December 2020 were analyzed.The associations between donor,recipient,or donor-recipient transplant patterns by sex and the post-LT outcomes were studied with propensity score matching(PSM).The survival associated with different sex-based donor-recipient transplant patterns was further studied.Results:Among 3,769 patients enrolled in this study,the 1-,3-,and 5-year overall survival(OS)rates of patients with HCC after LT were 96.1%,86.4%,and 78.5%,respectively,in female recipients,and 95.8%,79.0%,and 70.7%,respectively,in male recipients after PSM(P=0.009).However,the OS was comparable between recipients with female donors and male donors.Multivariate analysis indicated that male recipient sex was a risk factor for post-LT survival(HR=1.381,P=0.046).Among the donor-recipient transplant patterns,the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival(P<0.05).Conclusions:Our findings highlighted that the post-LT outcomes of female recipients were significantly superior to those of male recipients,and the male-male donor-recipient transplant pattern was associated with the poorest post-LT survival.Livers from male donors may provide the most benefit to female recipients.Our results indicate that sex should be considered as a critical factor in organ allocation.

TuBG1 promotes hepatocellular carcinoma via ATR/P53-apoptosis and cycling pathways

Background:As reported,γ-tubulin(TuBG1)is related to the occurrence and development of various types of malignant tumors.However,its role in hepatocellular cancer(HCC)is not clear.The present study was to investigate the relationship between TuBG1 and clinical parameters and survival in HCC patients.Methods:The correlation between TuBG1 and clinical parameters and survival in HCC patients was ex-plored by bioinformatics analysis.Immunohistochemistry was used for the verification.The molecular function of TuBG1 was measured using colony formation,scratch assay,trans-well assay and flow cytometry.Gene set enrichment analysis(GSEA)was used to pick up the enriched pathways,followed by investigating the target pathways using Western blotting.The tumor-immune system interactions and drug bank database(TISIDB)was used to evaluate TuBG1 and immunity.Based on the TuBG1-related immune genes,a prognostic model was constructed and was further validated internally and externally.Results:The bioinformatic analysis found high expressed TuBG1 in HCC tissue,which was confirmed us-ing immunohistochemistry and Western blotting.After silencing the TuBG1 in HCC cell lines,more G1 arrested cells were found,cell proliferation and invasion were inhibited,and apoptosis was promoted.Furthermore,the silence of TuBG1 increased the expressions of Ataxia-Telangiectasia and Rad-3(ATR),phospho-P38 mitogen-activated protein kinase(P-P38MAPK),phospho-P53(P-P53),B-cell lymphoma-2 associated X protein(Bax),cleaved caspase 3 and P21;decreased the expressions of B-cell lymphoma-2(Bcl-2),cyclin D1,cyclin E2,cyclin-dependent kinase 2(CDK2)and CDK4.The correlation analysis of immunohistochemistry and clinical parameters and survival data revealed that TuBG1 was negatively corre-lated with the overall survival.The constructed immune prognosis model could effectively evaluate the prognosis.Conclusions:The increased expression of TuBG1 in HCC is associated with poor prognosis,which might be involved in the occurrence and development of HCC.

Development of a diagnostic nomogram for alpha-fetoproteinnegative hepatocellular carcinoma based on serological biomarkers

BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer-related death worldwide.Serum biomarkers play an important role in the early diagnosis and prognosis of HCC.Because a certain percentage of HCC patients are negative for alpha-fetoprotein(AFP),the diagnosis of AFP-negative HCC is essential to improve the detection rate of HCC.AIM To establish an effective model for diagnosing AFP-negative HCC based on serum tumour biomarkers.METHODS A total of 180 HCC patients were enrolled in this study.The expression levels of GP73,des-γ-carboxyprothrombin(DCP),CK18-M65,and CK18-M30 were detected by a fully automated chemiluminescence analyser.The variables were selected by logistic regression analysis.Several models were constructed using stepwise backward logistic regression.The performance of the models was compared using the C statistic,integrated discrimination improvement,net reclassification improvement,and calibration curves.The clinical utility of the nomogram was assessed using decision curve analysis(DCA).RESULTS The results showed that the expression levels of GP73,DCP,CK18-M65,and CK18-M30 were significantly greater in AFP-negative HCC patients than in healthy controls(P<0.001).Multivariate logistic regression analysis revealed that GP73,DCP,and CK18-M65 were independent factors for diagnosing AFP-negative HCC.By comparing the diagnostic performance of multiple models,we included GP73 and CK18-M65 as the model variables,and the model had good discrimination ability(area under the curve=0.946)and good goodness of fit.The DCA curves indicated the good clinical utility of the nomogram.CONCLUSION Our study identified GP73 and CK18-M65 as serum biomarkers with certain application value in the diagnosis of AFP-negative HCC.The diagnostic nomogram based on CK18-M65 combined with GP73 demonstrated good performance and effectively identified high-risk groups of patients with HCC.

Albumin–bilirubin grade as a predictor of survival in hepatocellular carcinoma patients with thrombocytopenia

BACKGROUND The models for assessing liver function,mainly the Child–Pugh(CP),albuminbilirubin(ALBI),and platelet–ALBI(PALBI)classifications,have been validated for use in estimating the prognosis of hepatocellular carcinoma(HCC)patients.However,thrombocytopenia is a common finding and may influence the prognostic value of the three models in HCC.AIM To investigate and compare the prognostic performance of the above three models in thrombocytopenic HCC patients.METHODS A total of 135 patients with thrombocytopenic HCC who underwent radical surgery were retrospectively analyzed.Preoperative scores on the CP,ALBI and PALBI classifications were estimated accordingly.Kaplan–Meier curves with logrank tests and Cox regression models were used to explore the significant factors associated with overall survival(OS)and recurrence-free survival(RFS).RESULTS The preoperative platelet counts were significantly different among the CP,ALBI and PALBI groups.After a median follow-up of 28 mo,39.3%(53/135)of the patients experienced postoperative recurrence,and 36.3%(49/135)died.Univariate analysis suggested thatα-fetoprotein levels,tumor size,vascular invasion,and ALBI grade were significant predictors of OS and RFS.According to the multivariate Cox regression model,ALBI was identified as an independent prognostic factor.However,CP and PALBI grades were not statistically significant prognostic indicators.CONCLUSION The ALBI grade,rather than CP or PALBI grade,is a significant prognostic indicator for thrombocytopenic HCC patients.

Monitoring of hepatocellular carcinoma

Screening for hepatocellular carcinoma in patients at risk is an evidence-based approach;however,adherence to the monitoring protocol recommended by international guidelines is difficult.Hence,there is a need to use the best screening options and refine the selection of patients at risk in the future.

Targeting therapy for hepatocellular carcinoma by delivering microRNAs as exosomal cargo

Exosomes,the smallest extracellular vesicles,have gained significant attention as key mediators in intercellular communication,influencing both physiological and pathological processes,particularly in cancer progression.A recent review article by Wang et al was published in a timely manner to stimulate future research and facilitate practical developments for targeted treatment of hepatocellular carcinoma using exosomes,with a focus on the origin from which exosomes derive.If information about the mechanisms for delivering exosomes to specific cells is incorporated,the concept of targeted therapy for hepatocellular carcinoma using exosomes could be more comprehensively understood.

Abnormal liver function(14.7%) had the most common grade 3 or higher AEs.Conclusions: A combination of low-dose cyclophosphamide with lenvatinib, pembrolizumab, and TACE is safe and effective for u HCC, showcasing a promising therapeutic strategy for managing uHCC.

Development of a nomogram for predicting liver transplantation prognosis in hepatocellular carcinoma

BACKGROUND At present,liver transplantation(LT)is one of the best treatments for hepatocellular carcinoma(HCC).Accurately predicting the survival status after LT can significantly improve the survival rate after LT,and ensure the best way to make rational use of liver organs.AIM To develop a model for predicting prognosis after LT in patients with HCC.METHODS Clinical data and follow-up information of 160 patients with HCC who underwent LT were collected and evaluated.The expression levels of alphafetoprotein(AFP),des-gamma-carboxy prothrombin,Golgi protein 73,cytokeratin-18 epitopes M30 and M65 were measured using a fully automated chemiluminescence analyzer.The best cutoff value of biomarkers was determined using the Youden index.Cox regression analysis was used to identify the independent risk factors.A forest model was constructed using the random forest method.We evaluated the accuracy of the nomogram using the area under the curve,using the calibration curve to assess consistency.A decision curve analysis(DCA)was used to evaluate the clinical utility of the nomograms.RESULTS The total tumor diameter(TTD),vascular invasion(VI),AFP,and cytokeratin-18 epitopes M30(CK18-M30)were identified as important risk factors for outcome after LT.The nomogram had a higher predictive accuracy than the Milan,University of California,San Francisco,and Hangzhou criteria.The calibration curve analyses indicated a good fit.The survival and recurrence-free survival(RFS)of high-risk groups were significantly lower than those of low-and middle-risk groups(P<0.001).The DCA shows that the model has better clinical practicability.CONCLUSION The study developed a predictive nomogram based on TTD,VI,AFP,and CK18-M30 that could accurately predict overall survival and RFS after LT.It can screen for patients with better postoperative prognosis,and improve longterm survival for LT patients.

Bioinformatics analysis and experimental validation of cystathionine-gamma-lyase as a potential prognosis biomarker in hepatocellular carcinoma

Background:Hepatocellular carcinoma(HCC)is a common malignant tumor with poor prognosis and high mortality worldwide.Although cystathionine-gamma-lyase(CSE)plays an important role in the development of multiple tumors,the clinical implication and potential mechanisms of CSE in HCC development remain elusive.Methods:In our study,the CSE expression in HCC was analyzed in Gene Expression Omnibus(GEO)and The Cancer Genome Atlas(TCGA)datasets and further confirmed by RT-qPCR and immunohistochemistry assays in HCC samples.Furthermore,the associations between CSE expression and HCC malignancy as well as survival were analyzed in GSE14520 and validated in HCC patients.Finally,the biological functions of CSE in HCC cells was assessed by CCK-8,flow cytometry and Western blotting.Results:Lower transcriptional and proteomic CSE expressions were found in HCC tissues in contrast to adjacent normal tissues.Decreased CSE mRNA expression was significantly associated with advanced clinicopathological features and poor outcomes in HCC patients from public database and our cohort.Following univariate and multivariate analyses of GSE14520 data showed that CSE expression was an independent prognostic indicator for the overall survival(OS)and recurrence-free survival(RFS)of HCC patients.In vitro experiments further explained that CSE might trigger HCC cell apoptosis by H2S.Conclusion:In summary,the present study identified the relationship between CSE expression and HCC malignancy as well as OS and RFS,indicating that CSE might be a potential prognostic biomarker and a novel therapeutic target for HCC.

Bile acids,gut microbiota,and therapeutic insights in hepatocellular carcinoma

Hepatocellular carcinoma(HCC)is a prevalent and aggressive liver malignancy.The interplay between bile acids(BAs)and the gut microbiota has emerged as a critical factor in HCC development and progression.Under normal conditions,BA metabolism is tightly regulated through a bidirectional interplay between gut microorganisms and BAs.The gut microbiota plays a critical role in BA metabolism,and BAs are endogenous signaling molecules that help maintain liver and intestinal homeostasis.Of note,dysbiotic changes in the gut microbiota during pathogenesis and cancer development can disrupt BA homeostasis,thereby leading to liver inflammation and fibrosis,and ultimately contributing to HCC development.Therefore,understanding the intricate interplay between BAs and the gut microbiota is crucial for elucidating the mechanisms underlying hepatocarcinogenesis.In this review,we comprehensively explore the roles and functions of BA metabolism,with a focus on the interactions between BAs and gut microorganisms in HCC.Additionally,therapeutic strategies targeting BA metabolism and the gut microbiota are discussed,including the use of BA agonists/antagonists,probiotic/prebiotic and dietary interventions,fecal microbiota transplantation,and engineered bacteria.In summary,understanding the complex BA-microbiota crosstalk can provide valuable insights into HCC development and facilitate the development of innovative therapeutic approaches for liver malignancy.

Aspirin suppresses hepatocellular carcinoma progression by inhibiting platelet activity

BACKGROUND Hepatocellular carcinoma(HCC)is the most common malignant liver disease in the world.Platelets(PLTs)are known to play a key role in the maintenance of liver homeostasis and the pathophysiological processes of a variety of liver diseases.Aspirin is the most classic antiplatelet agent.However,the molecular mechanism of platelet action and whether aspirin can affect HCC progression by inhibiting platelet activity need further study.AIM To explore the impact of the antiplatelet effect of aspirin on the development of HCC.METHODS Platelet-rich plasma,platelet plasma,pure platelet,and platelet lysate were prepared,and a coculture model of PLTs and HCC cells was established.CCK-8 analysis,apoptosis analysis,Transwell analysis,and real-time polymerase chain reaction(RT-PCR)were used to analyze the effects of PLTs on the growth,metastasis,and inflammatory microenvironment of HCC.RT-PCR and Western blot were used to detect the effects of platelet activation on tumor-related signaling pathways.Aspirin was used to block the activation and aggregation of PLTs both in vitro and in vivo,and the effect of PLTs on the progression of HCC RESULTS PLTs significantly promoted the growth,invasion,epithelial-mesenchymal transition,and formation of an inflammatory microenvironment in HCC cells.Activated PLTs promoted HCC progression by activating the mitogenactivated protein kinase/protein kinase B/signal transducer and activator of transcription three(MAPK/AKT/STAT3)signaling axis.Additionally,aspirin inhibited HCC progression in vitro and in vivo by inhibiting platelet activation.CONCLUSION PLTs play an important role in the pathogenesis of HCC,and aspirin can affect HCC progression by inhibiting platelet activity.These results suggest that antiplatelet therapy has promising application prospects in the treatment and combined treatment of HCC.

Hepatocellular carcinoma and musculoskeletal system: A narrative literature review

Musculoskeletal alterations in hepatocellular carcinoma(HCC)are less common than liver-related complications.However,they can significantly impact the quality of life and overall prognosis of patients with HCC.The main obstacle in the clinical assessment of HCC-induced musculoskeletal alterations is related to effective and timely diagnosis because these complications are often asym-ptomatic and unapparent during routine clinical evaluations.This narrative literature review aimed to provide a comprehensive overview of the contem-porary literature related to the changes in the musculoskeletal system in patients with HCC,focusing on its clinical implications and underlying etiopathogenetic mechanisms.Osteolytic bone metastases are the most common skeletal alterations associated with HCC,which could be associated with an increased risk of low-trauma bone fracture.Moreover,previous studies reported that osteopenia,sarcopenia,and myosteatosis are associated with poor clinical outcomes in patients with HCC.Even though low bone mineral density and sarcopenia are consistently reported as reliable predictors of pretransplantation and post-transplantation mortality in HCC patients,these complications are frequently overlooked in the clinical management of patients with HCC.Taken together,contemporary literature suggests that a multidisciplinary approach is essential for early recognition and clinical management of HCC-associated musculoskeletal alterations to improve patient prognosis.Further research into the mechanisms and treatment options for musculoskeletal complications is warranted to enhance our understanding and clinical management of this aspect of HCC.
