Outcomes and Quality of Life of Systemic Therapy in Advanced Hepatocellular Carcinoma

Atezolizumab and Bevacizumab Targeted-Therapy in Advanced Hepatocellular Carcinoma: A Systematic Review of Cost-effectiveness Analyses

BACKGROUND

Atezolizumab (ATZ) plus bevacizumab (BVC) co-administration is one of the newest systemic interventions in advanced hepatocellular carcinoma (AHCC). This treatment approach is more costly and effective than other therapeutic interventions, significantly improving AHCC survival and health-related quality of life.

AIM

This economic study aimed to systematically review all cost-effectiveness analyses of ATZ/BVC combination in AHCC.

METHOD

A comprehensive search in scientific databases was performed using a highly sensitive syntax to find all related economic evaluations. The target population was AHCC patients. The intervention was ATZ/BVC, which was compared with sorafenib, nivolumab, and other anticancer strategies. We included studies that reported quality-adjusted life-years (QALYs) and/or life-years, costs, and incremental cost-effectiveness ratio (ICER), and finally, the characteristics of included studies were categorized.

RESULTS

Out of 315 identified records, 12 cost-effectiveness analyses were eligible for inclusion in the systematic review. Treatment costs were significantly higher with ATZ/BVC in all studies (from 61,397 to 253,687 USD/patient compared to sorafenib and nivolumab, respectively). Incremental QALYs/patient varied from 0.35 to 0.86 compared to sintilimab/BVC and sorafenib. Although ICERs for drugs varied widely, all were united in the lack of cost-effectiveness of the ATZ/BVC. The willingness-to-pay threshold in all studies was lower than the ICER, which indicated a reluctance to pay for this treatment strategy by the health systems.

CONCLUSION

The ATZ/BVC combination is an expensive targeted immunotherapy in AHCC. Significant discounts in ATZ and BVC prices are essential for this novel approach to be cost-effective and extensively used.

miR-199a-3p increases the anti-tumor activity of palbociclib in liver cancer models

Palbociclib is in early-stage clinical testing in advanced hepatocellular carcinoma (HCC). Here, we investigated whether the anti-tumor activity of palbociclib, which prevents the CDK4/6-mediated phosphorylation of RB1 but simultaneously activates AKT signaling, could be improved by its combination with a PI3K/AKT/mTOR inhibitor in liver cancer models. The selective pan-AKT inhibitor, MK-2206, or the microRNA-199a-3p were tested in combination with palbociclib in HCC cell lines and in the TG221 HCC transgenic mouse model. The combination palbociclib/MK-2206 was highly effective, but too toxic to be tolerated by mice. Conversely, the combination miR-199a-3p mimics/palbociclib not only induced a complete or partial regression of tumor lesions, but was also well tolerated. After 3 weeks of treatment, the combination produced a significant reduction in number and size of tumor nodules in comparison with palbociclib or miR-199a-3p mimics used as single agents. Moreover, we also reported the efficacy of this combination against sorafenib-resistant cells in vitro and in vivo. At the molecular level, the combination caused the simultaneous decrease of the phosphorylation of both RB1 and of AKT. Our findings provide pre-clinical evidence for the efficacy of the combination miR-199a-3p/palbociclib as anti-HCC treatment or as a new approach to overcome sorafenib resistance.

Quality of life assessment of cabozantinib in patients with advanced hepatocellular carcinoma in the CELESTIAL trial

BACKGROUND

The CELESTIAL trial (NCT01908426) demonstrated overall survival benefit for cabozantinib versus placebo in patients with advanced hepatocellular carcinoma (aHCC) who had received prior sorafenib treatment. This analysis of CELESTIAL compared the impact of cabozantinib versus placebo on health-related quality of life (HRQoL).

MATERIALS AND METHODS

Health status was assessed using the EuroQol five-dimension five-level (EQ-5D-5L) questionnaire over the 800-day follow-up period. EQ-5D-5L health states were mapped to health utility scores using reference values for the UK population. Quality-adjusted life years (QALYs) were calculated for each treatment group as the area under the curve for the plot of health utility score over time. The between-treatment group difference in restricted mean QALYs was calculated by generalized linear models and adjusted for baseline differences. A difference of 0.08 in health utility score (or in QALY) was deemed a minimally important difference and to be clinically significant.

RESULTS

At week 5, the difference in mean health utility score between cabozantinib and placebo was -0.097 (95% confidence interval [95% CI]: -0.126, -0.067; p ≤ 0.001). Between-group differences in health utility scores diminished over time and were generally non-significant. The cabozantinib group accrued more QALYs than the placebo group over follow-up. Differences in mean QALYs (cabozantinib minus placebo) were statistically and clinically significant, ranging from +0.092 (95% CI: 0.016, 0.169) to +0.185 (95% CI: 0.126, 0.243) in favour of cabozantinib, depending on the reference value set used.

CONCLUSIONS

These HRQoL findings support a positive benefit-risk profile for cabozantinib in previously treated patients with aHCC.

Safety of ramucirumab treatment in patients with advanced hepatocellular carcinoma and elevated alpha-fetoprotein

INTRODUCTION

Hepatocellular carcinoma (HCC) is the second most common cause of cancer-induced deaths worldwide, and limited therapeutic options are available for patients with advanced disease. Ramucirumab, a monoclonal antibody that blocks the vascular endothelial growth factor (VEGF) receptor-2, is the first biomarker-selected systemic agent with therapeutic efficacy, tolerability, and favorable patient-reported outcomes in patients with advanced HCC and elevated serum α-fetoprotein levels ≥400 ng/mL, who are resistant or intolerant to sorafenib therapy. However, treatment-induced adverse events (AEs), such as hypertension, proteinuria, bleeding, thromboembolism, and gastrointestinal perforation remain challenging and potentially fatal concerns.

AREAS COVERED

This review discusses the published or ongoing studies and subgroup analyses on ramucirumab therapy in patients with advanced HCC. We present information on the risks of ramucirumab-induced common or rare AEs and their management.

EXPERT OPINION

Ramucirumab toxicity secondary to VEGF inhibition is similar to the AEs that are known to be associated with other VEGF-blocking antibodies. Common AEs can be safely treated using conventional measures; however, rare and potentially fatal AEs necessitate close monitoring. With regard to the safety profile, more promising ramucirumab-containing combination therapies are likely to pave the future path for effective HCC treatment.

Investigation on returning to work in liver cancer survivors in Taiwan: a 5-year follow-up study

BACKGROUND

Primary liver cancer is the fifth most common malignancy and limits patients' quality of life and working ability. Return to work after cancer treatment is an important step in social recovery. In addition, return to work represents the recovery of financial ability and improvements in self-confidence. The purpose of this article is to discuss the relationship between return to work and various covariables in workers with liver cancer.

METHODS

The national registry cohort study collected adult workers newly diagnosed with liver cancer from 2004 to 2010 in Taiwan. There were 2451 workers included in our study. Primary liver cancer was diagnosed by using the International Classification of Diseases for Oncology code. Return to work after liver cancer survival was determined as returning to the same work or reemployment within five years after cancer diagnosis. The associations between independent variables and return to work were analyzed by Cox proportional hazard models.

RESULTS

Workers who underwent surgery were more likely to return to work not only in the 2nd year but also in the 5th year. A lower survival rate was noted in the non-return-to-work group (p < 0.001) among all patients with liver cancer. The completely adjusted model identified that the rate of return to work was related to all-cause mortality with a hazard ratio of 0.244 (95% Confidence Intervals: 0.235-0.253).

CONCLUSIONS

Our study indicated the impacts of treatment on the return to work of liver cancer survivors. In addition, in patient with liver cancer, return to work had positive effect on the survival rate.

PLGA nanoparticles containing α-fetoprotein siRNA induce apoptosis and enhance the cytotoxic effects of doxorubicin in human liver cancer cell line

Hepatocellular carcinoma (HCC) is one of the most common cancers and is a leading cause of death. Delivery of therapeutic molecules, e.g., siRNA, to HCC cells could potentially be an alternative treatment for HCC. In this study, the siRNA targeting α-fetoprotein (AFP) mRNA was found to specifically induce apoptosis and significant cell death in HepG2 cells. It also enhanced the cytotoxic effects of doxorubicin by about two-fold, making it the candidate therapeutic molecule for HCC treatment. To deliver the siRNAs into HCC cells, the AFP siRNAs were loaded into the nanoparticles based on poly (lactic-co-glycolic) acid (PLGA). These nanoparticles induced apoptosis in HepG2 cells and synergistically increased the cytotoxicity of doxorubicin. In summary, the delivery of the AFP siRNA-loaded PLGA nanoparticles in combination with doxorubicin could be a very promising approach for the treatment of HCC.

CircRNA profiling identifies circRNF180 as a tumor suppressor in hepatocellular carcinoma

Aim: To explore the expression profiles and functions of circRNAs in hepatocellular carcinoma (HCC). Materials & methods: We obtained circRNA expression profiles through RNA sequencing. Expression levels of circRNAs were confirmed by quantitative real-time PCR. The effects on HCC progression were determined using Cell Counting Kit 8, clone formation and transwell assays. Results: We identified 114 upregulated and 144 downregulated circRNAs in HCC tissues. The results of quantitative real-time PCR showed that circGNAO1, circRNF180 and circMERTK were significantly downregulated in HCC tissues, whereas circSNX6 was significantly upregulated. CircRNF180 was associated with microvascular invasion. Overexpression of circRNF180 inhibits the proliferation, colony formation, migration and invasion of HCC cells. Conclusion: CircRNF180 may function as a tumor suppressor and could serve as a potential biomarker and therapeutic target in HCC.

Identifying the Prognostic Risk Factors of Synaptojanin 2 and Its Underlying Perturbations Pathways in Hepatocellular Carcinoma

Synaptojanin 2 (SYNJ2) regulates cell proliferation and apoptosis via dephosphorylating plasma membrane phosphoinositides. Aim of this study is to first seek the full-scale expression levels and potential emerging roles of SYNJ2 in hepatocellular carcinoma (HCC). We systematically analyzed SYNJ2 mRNA expression and protein levels in HCC tissues based on large-scale data and in-house immunohistochemistry (IHC). The clinical significance and risk factors for SYNJ2-related HCC cases were identified. A nomogram of prognosis was created and its performance was validated by concordance index (C-index) and shown in calibration plots. Based on the identified differentially coexpressed genes (DCGs) of SYNJ2, enriched annotations and potential pathways were predicted, and the protein interacting networks were mapped. Upregulated SYNJ2 in 3,728 HCC and 3,203 non-HCC tissues were verified and in-house IHC showed higher protein levels of SYNJ2 in HCC tissues. Pathologic T stage was identified as a risk factor. Upregulated mRNA levels and mutated SYNJ2 might cause a poorer outcome. The C-index of the nomogram model constructed by SYNJ2 level, age, gender, TNM classification, grade, and stage was evaluated as 0.643 (95%CI = 0.619–0.668) with well-calibrated plots. A total of 2,533 DCGs were extracted and mainly functioned together with SYNJ2 in metabolic pathways. Possible transcriptional axis of CTCF/POLR2A-SYNJ2/INPP5B (transcription factor-target) in metabolic pathways was discovered based on ChIP-seq datasets. In summary, transcriptional regulatory axis CTCF/POLR2A-SYNJ2 might influence SYNJ2 expression levels. Increased SYNJ2 expression level could be utilized for predicting HCC prognosis and potentially accelerates the occurrence and development of HCC via metabolic perturbations pathways.

Access to Liver Transplantation for Hepatocellular Carcinoma: Does Candidate Age Matter?

BACKGROUND

Liver transplantation (LT) offers an effective alternative treatment for unresectable hepatocellular carcinoma (HCC). Despite its growing acceptance and longer life expectancy rates, survival data in older patients are conflicting and consensus guidelines are lacking in terms of a cut-off age range for operations.

STUDY DESIGN

We explored our prospectively maintained institutional database to identify patients diagnosed with HCC between January 1, 2002 and December 31, 2019. Long-term oncologic outcomes were analyzed in patients undergoing LT or hepatic resection, with patient age considered as the primary variable.

RESULTS

In total, 1,629 patients with HCC were identified, of whom 700 were considered for curative operations (LT, n = 538; resection, n = 162). Patients older than 65 years were less likely to be considered for LT (p < 0.01), although there were no age-related differences in the de-listing rate among age groups (p = 0.90). Older patients had overall survival (OS) outcomes comparable with younger patients after LT (3-year OS: 85.5% vs 84%; 5-year OS: 73.9% vs 77%; p = 0.26). Long-term survival was lower in the group who underwent resection, however, older patients still demonstrated equivalent OS outcomes (3-year OS: 59% vs 64.8%; 5-year OS: 44.8% vs 49%; p = 0.13). There were no differences in the development of local or distant metastatic disease between groups.

CONCLUSIONS

Although older candidates were less likely to be considered for LT in the management of HCC, judicious matching can lead to OS data comparable with their younger counterparts. Previous age misconceptions need to be challenged without the concern of worse long-term oncologic outcomes after surgery.

Effect of urea cream on sorafenib-associated hand-foot skin reaction in patients with hepatocellular carcinoma: A multicenter, randomised, double-blind controlled study

BACKGROUND

Hand-foot skin reaction (HFSR) is the most common adverse event during sorafenib treatment in patients with hepatocellular carcinoma (HCC). In the present study, we aimed to investigate the role of urea cream in the prevention of HFSR or amelioration of HFSR severity.

PATIENTS AND METHODS

Patients with HCC were treated with either placebo cream or urea cream for 12 weeks concomitantly with sorafenib treatment. HFSR development, the Hand-Foot Skin Reaction and Quality of Life (HF-QoL) questionnaire score, and adverse events were assessed at 2, 4, 8 and 12 weeks.

RESULTS

Of the 288 patients, 247 patients, with 117 patients in the placebo control group and 130 patients in the urea cream group, were analysed. The urea cream group showed a trend towards a lower cumulative incidence of any-grade HFSR (log-rank, P = 0.247) and severe HFSR of grade II or higher (log-rank, P = 0.394) without statistical significance. In the incidence by time point, the incidence of severe HFSR of grade II or higher was significantly lower in the urea cream group than in the placebo control group at 2 weeks (13.8% versus 23.9%, P = 0.042). The urea cream group showed a significantly better HF-QoL questionnaire score than the placebo control group (11.8 versus 19.7, P = 0.014) at 12 weeks.

CONCLUSIONS

Treatment with urea cream showed a lower incidence of severe sorafenib-induced HFSR at 2 weeks and reduced the tendency of HFSR development in HCC patients. Therefore, treatment with urea cream may be considered for prophylaxis or improvement of HFSR grade in HCC patients treated with sorafenib.

Ramucirumab in elderly patients with hepatocellular carcinoma and elevated alpha-fetoprotein after sorafenib in REACH and REACH-2

BACKGROUND & AIMS

Limited data on treatment of elderly patients with hepatocellular carcinoma (HCC) increase the unmet need. REACH and REACH-2 were global phase III studies of ramucirumab in patients with HCC after prior sorafenib, where patients with alpha-fetoprotein (AFP) ≥400 ng/mL showed an overall ssurvival (OS) benefit for ramucirumab. These post-hoc analyses examined efficacy and safety of ramucirumab in patients with HCC and baseline AFP ≥ 400 ng/mL by three prespecified age subgroups (<65, ≥65 to <75 and ≥75 years).

METHODS

Individual patient data were pooled from REACH (baseline AFP ≥400 ng/mL) and REACH-2. Kaplan-Meier and Cox proportional hazards regression methods (stratified by study) assessed OS, progression-free survival (PFS), time to progression (TTP) and patient-reported outcomes (Functional Hepatobiliary System Index-8 [FHSI-8] score).

RESULTS

A total of 542 patients (<65 years: n = 302; ≥65 to <75 years: n = 160; ≥75 years: n = 80) showed similar baseline characteristics between ramucirumab and placebo. Older subgroups had higher hepatitis C and steatohepatitis incidences, and lower AFP levels, than the <65 years subgroup. Ramucirumab prolonged OS in patients <65 years (hazard ratio [HR], 0.753; 95% CI 0.581-0.975), ≥65 to <75 years (0.602; 0.419-0.866) and ≥75 years (0.709; 0.420-1.199), PFS and TTP irrespective of age. Ramucirumab showed similar overall safety profiles across subgroups, with a consistent median relative dose intensity ≥97.8%. A trend towards a delay in symptom deterioration in FHSI-8 with ramucirumab was observed in all subgroups.

CONCLUSIONS

In this post-hoc analysis, ramucirumab showed a survival benefit across age subgroups with a tolerable safety profile, supporting its use in advanced HCC with elevated AFP, irrespective of age, including ≥75 years.

Interleukin 22 in Liver Injury, Inflammation and Cancer

Interleukin 22(IL-22), a member of the IL-10 cytokine family and is an emerging CD4+Th cytokine that plays an important role in anti-microbial defense, homeostasis and tissue repair. We are interested in IL-22 as it has the double function of suppressing or encouraging inflammation in various disease models including hepatic inflammation. As a survival factor for hepatocytes, IL-22 plays a protective role in many kinds of liver diseases, such as hepatitis, liver fibrosis, or hepatocellular carcinoma (HCC) by binding to the receptors IL-22R1 and IL-10R2. Overexpression of IL-22 reduces liver fibrosis by attenuating the activation of hepatic stellate cell (the main cell types involved in hepatic fibrosis), and down-regulating the levels of inflammatory cytokines. Administration of exogenous IL-22 increases the replication of hepatocytes by inhibiting cell apoptosis and promoting mitosis, ultimately plays a contributing role in liver regeneration. Furthermore, treatment with IL-22 activates hepatic signal transducer and activator of transcription 3 (STAT3), ameliorates hepatic oxidative stress and alcoholic fatty liver, effectively alleviate the liver damage caused by alcohol and toxicant. In conclusion, the hepatoprotective functions and liver regeneration promoting effect of IL-22 suggests the therapeutic potential of IL-22 in the treatment of human hepatic diseases.

Eukaryotic initiation factor 3e subunit is positively associated with tumorigenesis and development of hepatocellular carcinoma

BACKGROUND

Eukaryotic initiation factor 3 (eIF3) is one of the most complex translation initiation factors in mammalian cells. Eukaryotic initiation factor 3e subunit (eIF3e) is a member of the 13 subunits of eIF3, and its dysregulated expression is closely related to the occurrence and development of cancer. However, the role of eIF3e in different types of malignant tumor is contradictory. So far, the role of eIF3e in primary hepatocellular carcinoma (HCC) has been unknown.

AIM

To study the role of eIF3e during tumorigenesis and development of HCC.

METHODS

Freshly isolated liver cancer tissues and adjacent tissues from five randomly selected patients with HCC were collected during operation of liver transplantation. The levels of mRNA and protein expression of eIF3e in liver cancer tissues and adjacent tissues were detected by qRT-PCR and Western blot, respectively. An eIF3e-containing plasmid, pcDNA3.1-eIF3e, or an eIF3e-silencing short hairpin RNA plasmid, pSuper-sheIF3e, was transiently transfected into HepG2 cells, and the levels of mRNA and protein expression of eIF3e were analyzed by qRT-PCR and Western Blot, respectively, to confirm that eIF3e expression was up-regulated by pcDNA3.1-eIF3e or down-regulated by pSuper-sheIF3e. To study the effect of altered eIF3e expression on cellular behavior, Cell Counting Kit-8 approach was used to evaluate cell proliferation, scratch test was used to observe cell migration, and flow cytometric analysis was performed to assess cell apoptosis. Finally, the effect of eIF3e on tumor growth was evaluated by tumor-forming experiment in nude mice.

RESULTS

Compared with the adjacent tissues, eIF3e was up-regulated in HCC tissues. Cellular experiments showed that the transcription levels of eIF3e mRNA in HepG2 and Huh7 cells were higher than those in HL7702 cells. After HepG2 cells were transiently transfected by pcDNA3.1-eIF3e or pSuper-sheIF3e, it was found that up-regulated eIF3e increased proliferation and migration of HepG2 cells, but had no effect on cellular apoptosis, while down-regulated eIF3e decreased proliferation and migration, and accelerated apoptosis. The results in nude mice showed that eIF3e promoted tumor growth in vivo.

CONCLUSION

Overexpression of eIF3e is positively associated with tumorigenesis and development of HCC. Therefore, eIF3e has the potential to become a novel target for clinical treatment of HCC.

The aryl hydrocarbon receptor ligand ITE inhibits cell proliferation and migration and enhances sensitivity to drug-resistance in hepatocellular carcinoma

Aryl hydrocarbon receptor (AHR), a ligand-activated transcription factor, is considered as a crucial gene during tumor formation and progress. Among various ligands, 2-(1'H-indole-3'-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE) has been evaluated to share a broad spectrum of biological activities. However, the specific effects and potential mechanisms of ITE against hepatocellular carcinoma remain unclear. Here we explored whether ITE exerted antitumor activity against hepatocellular carcinoma (HCC) cells and its potential mechanisms in vitro and in vivo. We found that ITE could markedly inhibit proliferation of HCCLM3 and SMMC-7721 cells and induce G0/G1 arrest and apoptosis with alterations of expressions of the related proteins. Also, ITE could prohibit the process of migration and invasion evaluated by transwell assay. Moreover, ITE exhibited remarkable capability to repress the growth of HCCLM3-SR cells and induce apoptosis in contrast to sorafenib. Additionally, ITE also showed potent antitumor activity against the HCCLM3 xenograft by prohibiting tumor growth without any toxicity to mice. Mechanistically, AHR activation by ITE was attributed to inhibition of HCC cells as AHR knockdown would abolish ITE-induced suppression in HCC cells, and overexpression of AHR would potentiate antitumor activity regulated by ITE. Our data suggested that ITE manifested a marked antitumor effect against HCC cells both in vitro and in vivo via AHR activation mainly through inducing G1/G0 arrest and apoptosis and inhibiting the process of migration and invasion. Furthermore, we also found the PI3K/AKT pathway was involved in sorafenib-induced resistance and ITE could restore sensitivity by suppressing the PI3K/AKT pathway. Collectively, our study revealed that ITE would be a promising therapeutic agent to deal with HCC and an alternative for drug-resistant HCC.

Locoregional Therapies in the Treatment of 3- to 5-cm Hepatocellular Carcinoma: Critical Review of the Literature

OBJECTIVE. Treatment options for hepatocellular carcinoma (HCC) continue to expand. However, given the complexity of the patients including factors such as codominant cirrhosis or portal hypertension and transplant status, it can be difficult to know which treatment is most advantageous. The choice of HCC treatment is perhaps most complex in the setting of HCCs that are 3-5 cm. This article reviews the evidence for locoregional therapies in treating 3- to 5-cm HCCs. CONCLUSION. Combination therapy with transarterial chemoembolization (TACE) and ablation has the most robust and highest level of evidence to support its efficacy and therefore should be considered first-line therapy for nonresectable HCCs that measure 3-5 cm. The studies support that TACE followed by ablation is superior to either TACE alone or ablation alone. Data for transarterial radioembolization (TARE) to treat HCCs in this specific size range are very limited. Additional data are needed about the comparative effectiveness of TACE-ablation combination and TARE and how the TACE-ablation combination compares with surgical resection.

Overexpression of COL24A1 in Hepatocellular Carcinoma Predicts Poor Prognosis: A Study Based on Multiple Databases, Clinical Samples and Cell Lines

Purpose

Hepatocellular carcinoma (HCC) ranks as the second leading cause of cancer-related deaths worldwide and its incidence tends to increase globally. Current biomarkers can hardly reflect diagnostic significance and therapeutic efficiency accurately. The role of collagen 24A1 (COL24A1) in HCC, as a member of the collagen family, remains unclear and needs to be proved.

Methods

HCC-associated RNA sequencing datasets were obtained from The Cancer Genome Atlas (TCGA), International Cancer Genome Consortium (ICGC) and Oncomine databases. R language was used to screen and analyze the differential expression genes (DEGs). Gene Ontology (GO) pathway analyses of DEGs were carried out using g:profiler. Then, the STRING database and cytoscape software were applied to estimate the correlations between DEGs. GEPIA and HCCDB database were used to verify and analyze these results. Finally, qPCR and immunohistochemistry staining on clinical samples and HCC cell lines were conducted to further verify the above results.

Results

The expression of COL24A1 in HCC tissues was significantly higher than that in normal hepatic (NH) tissues. The analysis of TCGA and Oncomine database samples proved that COL24A1 expression was connected with tumor grade, tumor stage and pathologic stage. Meanwhile, the overall survival (OS) curve also validated that high expression of COL24A1 indicated poor prognosis. And the above results have been verified in our clinical samples and HCC cell lines. Furthermore, there is a significant increase of the expression of COL24A1 in various tumors. COL24A1, together with other interactive proteins, has a significant effect on the prognosis of HCC.

Conclusion

Overall, COL24A1 may be an oncogene in the development of HCC. Also, the overexpression of COL24A1 in HCC may help diagnose HCC and evaluate prognosis.
