Predictors of Non-response to Atezolizumab Plus Bevacizumab in Patients With Unresectable Hepatocellular Carcinoma: A Multicentre Real World Study (HCC-AB Study)

Background

The approved immunotherapies for patients with advanced HCC are Atezolizumab and Bevacizumab. However, patients in India present late and healthcare is often available through self-financing. To rationalise the therapy, we conducted a large multicentre study to identify the baseline predictors of non-response to atezolizumab and bevacizumab in advanced unresectable HCC.

Methods

A dose of atezolizumab 1200 mg and bevacizumab 15 mg/kg was used every 3 weeks from 6 centres across India. A total of 278 patients were screened, and 160 were included in the study. The study included patients with locally advanced metastatic or inoperable hepatocellular carcinoma who were at least 18 years of age and those who received <3 injections were excluded. Fifty-four percent of the included patients were BCLC-B and 46% were BCLC-C. The primary objective was to study overall survival and progression-free survival. While identifying radiological response, objective response rate and adverse effects were secondary objectives.

Results

The mean age was 61.9 ± 11.7 years, 88% were male, 55% had NASH, 16.3% had hepatitis C, 18.8% had hepatitis B and the rest were alcohol. The mean Model for End-Stage Liver Disease (MELD) is 12.05 ± 4.46, Albumin-Bilirubin Score (ALBI) is -2.04 ± 0.57. Fifty-five percent received first-line and 45% as second/other line therapy. The median overall survival was 10 (95% confidence interval [CI]: 6.1-15.6) months. Progression-free survival was found to be 8 (95%CI: 5.1-14.7) months overall. Eleven (6.9%) achieved complete response, 28 (17.5%) partial response, 33 (20.6%) had stable disease and 88 (55%) had progressive disease. On multivariate analysis, CRP>1 mg/dl (P-0.007), PIVKA-II>400 mAU/mL (P-0.019), AFP>100 ng/ml (P-0.009), presence of diabetes (P-0.042) were associated with non-response to atezolizumab and bevacizumab injection. Fifty-three percent of patients developed any grade of adverse effect, and 20% developed grade 3/4 adverse events amounting to the stoppage of therapy.

Conclusion

Non-response to atezolizumab and bevacizumab immunotherapy was predicted by CRP>1 mg/dl, PIVKA-II>400mAU/ml, AFP>100 ng/ml and the presence of diabetes.

Bridging diabetes and cancer: harnessing biomarkers as dual sentinels for diagnosis, prognosis, and therapeutic advancements

The complex two-way relationship between diabetes mellitus (DM) and cancer poses a significant global health challenge. Shared mechanisms such as hyperinsulinemia, chronic inflammation, and oxidative stress create an environment that fosters cancer development, increasing the risk for certain cancers in individuals with diabetes, including pancreatic, colorectal, breast, liver, and endometrial malignancies. In this context, biomarkers emerge as essential tools, offering a means to untangle the connections between these two conditions by providing insights into early detection, diagnosis, prognosis, and treatment monitoring. For diabetic patients, biomarkers are particularly valuable as they help differentiate between changes caused by cancer and those driven by metabolic imbalances, illuminating disease evolution. This review examines the unique challenges encountered by diabetic patients with cancer, emphasizing the contributions of targeted biomarkers in identifying cancer subtypes, predicting outcomes, and guiding treatment decisions. We explore organ-specific biomarker profiles across various cancers, including pancreatic, colorectal, breast, liver, and lung, highlighting their potential to enhance diagnostic precision and enable personalized treatment strategies. Ultimately, we aim to illustrate how a deeper understanding of biomarker signatures can inform innovative clinical approaches and improve care for patients facing the dual burden of diabetes and cancer.

Statin use and risk of HCC in patients with MASLD and T2DM: an umbrella review and meta-analysis

BACKGROUND

The effect of statin use on hepatocellular carcinoma (HCC) in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) or type two diabetes mellitus (T2DM) is still unclear. In this umbrella review, we aimed to assess the available evidence for the association of statin use and HCC risk in the target population.

METHODS

We carried out an umbrella review of previous systematic reviews/meta-analyses indexed in Cochrane, Embase, Scopus, and PubMed databases and published between Jan 1st, 2013, and Oct 22, 2024. We used random effects models to recalculate summary risk estimates for HCC incidence. Using A Measurement Tool to Assess methodological quality of systematic Review (AMSTAR2) tool, two independent reviewers evaluated each article for eligibility and methodologic quality and gathered data from the included studies.

RESULTS

Of the initially identified 1,038 systematic reviews/meta-analyses, three non-overlapping studies with medium/high quality were included for qualitative synthesis. Statin use in people with T2DM was reported in six studies belonging to two meta-analyses. The results showed that statins were associated with a decreased risk of HCC (RR: 0.16, 95% CI: [0.03, 0.98]). However, the association was nonsignificant in patients with MASLD comprising five studies from one meta-analysis (RR: 0.89, 95% CI: [0.56, 1.40]).

CONCLUSION

Statin use is associated with a decreased incidence of HCC in people with T2DM. In patients with MASLD, the association is not significant. However, the effects of other variables including the stage of inflammation and/or liver fibrosis on the outcome need to be explored in future studies.

Changes in systemic immune-inflammation index (SII) predict the prognosis of patients with hepatitis B-related hepatocellular carcinoma treated with lenvatinib plus PD-1 inhibitors

PURPOSE

This study aimed to evaluate the prognostic significance of changes in inflammatory markers in patients with Hepatitis B virus-related hepatocellular carcinoma (HBV-HCC) treated with first-line lenvatinib plus a programmed cell death protein 1 (PD-1) inhibitor.

METHODS

This study retrospectively included 117 HBV-HCC patients treated with first-line lenvatinib in combination with a PD-1 inhibitor. Independent factors affecting progression-free survival (PFS) and overall survival (OS) were explored based on baseline indicators and inflammatory markers changes after one treatment cycle.

RESULTS

Multivariate analysis revealed that an alpha-fetoprotein (AFP) level ⩾ 400 ng/mL [hazard ratio (HR), 1.69; 95% confidence interval (CI), 1.11-2.58; P = 0.01] was identified as an independent risk factor, platelet-to-neutrophil ratio (PNR) ⩽ 65.43 (HR 0.50; 95% CI 0.30-0.84; P < 0.01 ) and SII ⩽ 539.47 (HR 0.54; 95% CI 0.30-0.96; P = 0.03) were identified as independent protective factors for PFS. Additionally, multivariate analysis demonstrated that AFP ⩾ 400 ng/mL, HBV-HCC patients with diabetes mellitus (DM), and SII > 303.66 were independent risk factors of OS. The patients whose SII had increased after one cycle of treatment showed a poorer PFS (HR 1.61; 95 %CI 1.10-2.37; P = 0.015) and OS (HR 1.76; 95 % CI 1.15-2.70; P = 0.009) than patients whose SII had decreased. The objective response rate (ORR) was higher in the SII-decreased patients (47.5% vs 32.5%, P = 0.11). Mann-Whitney test found a significant difference in therapeutic response between the SII-increased patients and the SII-decreased patients (P = 0.04).

CONCLUSION

SII can be associated with outcomes in patients with HBV-HCC treated with first-line lenvatinib plus PD-1 inhibitors.

Innovative Drugs First Implemented in Type 2 Diabetes Mellitus and Obesity and Their Effects on Metabolic Dysfunction-Associated Steatohepatitis (MASH)-Related Fibrosis and Cirrhosis

Metabolic dysfunction-associated steatotic liver disease (MASLD), a progressive liver disease frequently associated with metabolic disorders such as type 2 diabetes mellitus (T2DM) and obesity, has the potential to progress symptomatically to liver cirrhosis and, in some cases, hepatocellular carcinoma. Hence, an urgent need arises to identify and approve new therapeutic options to improve patient outcomes. Research efforts have focused on either developing dedicated molecules or repurposing drugs already approved for other conditions, such as metabolic diseases. Among the latter, antidiabetic and anti-obesity agents have received the most extensive attention, with pivotal trial results anticipated shortly. However, the primary focus underlying successful regulatory approvals is demonstrating a substantial efficacy in improving liver fibrosis and preventing or ameliorating cirrhosis, the key advanced outcomes within MASLD progression. Besides liver steatosis, the ideal therapeutic candidate should reduce inflammation and fibrosis effectively. Although some agents have shown promise in lowering MASLD-related parameters, evidence of their impact on fibrosis and cirrhosis remains limited. This review aims to evaluate whether antidiabetic and anti-obesity drugs can be safely and effectively used in MASLD-related advanced fibrosis or cirrhosis in patients with T2DM. Our paper discusses the molecules closest to regulatory approval and the expectation that they can address the unmet needs of this increasingly prevalent disease.

Risk and Prognosis of Hepatocellular Carcinoma in Mexican Americans with Type 2 Diabetes Mellitus

Introduction

Hepatocellular carcinoma (HCC) disproportionately affects Hispanic persons with higher age-specific incidence and increased mortality rates compared to non-Hispanic Whites. These high rates of incidence and mortality may be explained by the variation in risk factors. Given the high prevalence of type 2 diabetes mellitus (DM) among the Hispanic population, we aimed to assess the risk and prognosis of HCC in Mexican Americans with type 2 DM with consideration of treatment for DM.

Methods

A case-control study of 241 Mexican American HCC patients and 500 healthy controls in Texas was conducted. Multivariable logistic regression analysis was performed to determine the association between type 2 DM and HCC risk while adjusting for other risk factors. Also, a restricted analysis of patients with type 2 DM was conducted to determine the effects of age at onset and duration of DM on HCC risk. Interactions among DM, heavy alcohol consumption, and viral hepatitis infection were examined. Overall survival was examined, and multivariable Cox proportional hazards regression analysis was performed for HCC patients with type 2 DM.

Results

The adjusted odds ratio (AOR) for DM was 2.74 (P < 0.01). Compared with patients who had DM for 2-10 years, those who had it for at least 20 years had an AOR of 4.60 (P = 0.04). Metformin use was associated with a reduced risk of death in HCC cases with type 2 DM, with a hazard ratio of 0.72 (P = 0.01) as compared with non-users.

Conclusion

Our results demonstrate that type 2 DM was independently associated with increased risk of HCC among Mexican Americans. Metformin use was associated with improved survival among HCC patients with type 2 DM. Type 2 DM significantly increased the risk of HCC alone and in conjunction with other parameters of metabolic syndrome in the Mexican American population after adjusting for other risk factors.

Non-receptor Type PTPases and their Role in Controlling Pathways Related to Diabetes and Liver Cancer Signalling

The role of non-receptor type Protein Tyrosine Phosphatase (PTPases) in controlling pathways related to diabetes and Hepatocellular Carcinoma (HCC) is significant. The insulin signal transduction pathway is regulated by the steady-state phosphorylation of tyrosyl residues of the insulin receptor and post-receptor substrates. PTPase has been shown to have a physiological role in the regulation of reversible tyrosine phosphorylation. There are several non-receptor type PTPases. PTPase containing the SH-2 domain (SHP-2) and the non-receptor type PTPase (PTP1B; encoded by the PTPN1 gene) are involved in negative regulation of the insulin signaling pathway, thereby indicating that the pathway can be made more efficient by the reduction in the activity of specific PTPases. Reduction in insulin resistance may be achieved by drugs targeting these specific enzymes. The modifications in the receptor and post-receptor events of insulin signal transduction give rise to insulin resistance, and a link between insulin-resistant states and HCC has been established. The cancer cells thrive on higher levels of energy and their growth gets encouraged since insulin-resistant states lead to greater glucose levels. Cancer, hyperglycemia, and hypoglycemia are highly linked through various pathways hence, clarifying the molecular mechanisms through which non-receptor type PTPase regulates the insulin signal transduction is necessary to find an effective target for cancer. Targeting the pathways related to PTPases; both receptor and non-receptor types, may lead to an effective candidate to fight against diabetes and HCC.

Metformin in Antiviral Therapy: Evidence and Perspectives

Metformin, a widely used antidiabetic medication, has emerged as a promising broad-spectrum antiviral agent due to its ability to modulate cellular pathways essential for viral replication. By activating AMPK, metformin depletes cellular energy reserves that viruses rely on, effectively limiting the replication of pathogens such as influenza, HIV, SARS-CoV-2, HBV, and HCV. Its role in inhibiting the mTOR pathway, crucial for viral protein synthesis and reactivation, is particularly significant in managing infections caused by HIV, CMV, and EBV. Furthermore, metformin reduces oxidative stress and reactive oxygen species (ROS), which are critical for replicating arboviruses such as Zika and dengue. The drug also regulates immune responses, cellular differentiation, and inflammation, disrupting the life cycle of HPV and potentially other viruses. These diverse mechanisms suppress viral replication, enhance immune system functionality, and contribute to better clinical outcomes. This multifaceted approach highlights metformin's potential as an adjunctive therapy in treating a wide range of viral infections.

Risk-stratified hepatocellular carcinoma screening according to the degree of obesity and progression to cirrhosis for diabetic patients with metabolic dysfunction-associated steatotic liver disease (MASLD) in Japan: a cost-effectiveness study

OBJECTIVE

To evaluate the cost-effectiveness of risk-stratified hepatocellular carcinoma (HCC) screening in diabetic patients with metabolic dysfunction-associated steatotic liver disease (MASLD).

DESIGN

A state-transition model from a healthcare payer perspective on a lifetime horizon.

SETTING

Japan.

POPULATION

A hypothetical cohort of 50-year-old diabetic patients with MASLD risk-stratified according to degree of obesity and progression to cirrhosis. Metabolic dysfunction-associated steatotic liver (MASL), metabolic dysfunction-associated steatohepatitis (MASH) and MASH cirrhosis are progressive manifestations of this specific type of liver disease.

INTERVENTION

Abdominal ultrasound (US), US with alpha-fetoprotein (AFP), US with AFP and lectin-reactive alpha-fetoprotein (AFP-L3), CT, extracellular contrast-media-enhanced MRI (ECCM-MRI), gadoxetic acid-enhanced MRI (EOB-MRI) and no screening.

MAIN OUTCOME MEASURE

Costs, quality-adjusted life-years (QALYs), incremental cost-effectiveness ratios (ICERs), early-stage HCC cases, advanced-stage HCC cases and HCC-related deaths.

RESULTS

EOB-MRI is the most cost-effective screening method for non-obese diabetic patients with MASH cirrhosis and for obese diabetic patients with MASH and MASH cirrhosis. Cost-effectiveness was sensitive to HCC incidence in non-obese diabetic patients with MASH cirrhosis and obese diabetic patients with MASH, and the adherence rate of HCC screening in obese diabetic patients with MASH. When the semiannual HCC incidence was between 0.008 and 0.0138 in non-obese diabetic patients with MASH cirrhosis, US with AFP was more cost-effective than EOB-MRI. Cost-effectiveness acceptability curves showed that EOB-MRI was 50.7%, 96.0% and 99.9% cost-effective in obese diabetic patients with MASH and non-obese diabetic patients with MASH cirrhosis, and obese diabetic patients with MASH cirrhosis at a willingness-to-pay level of $50 000 per QALY gained. Compared with no screening in 100 000 non-obese diabetic patients with MASH cirrhosis and obese diabetic patients with MASH cirrhosis, EOB-MRI reduced total costs by US$69 million and by US$142 million, increased lifetime effectiveness by 12 546 QALYs and by 15 815 QALYs, detected 17 873 and 21 014 early-stage HCC cases, and averted 2068 and 2471 HCC-related deaths, respectively.

CONCLUSIONS

Of all HCC screening methods for diabetic patients with MASH cirrhosis, EOB-MRI yields the greatest cost-saving with the highest QALYs, detects the greatest number of early-stage HCC cases and averts the greatest number of advanced-stage HCC cases and HCC-related deaths. The findings provide important insights for the precise implementation of risk-stratified HCC surveillance to reduce morbidity and mortality and improve the quality of life in diabetic patients with MASLD.

Integrative Network Pharmacology, Molecular Docking, and Dynamics Simulations Reveal the Mechanisms of Cinnamomum tamala in Diabetic Nephropathy Treatment: An In Silico Study

Diabetic nephropathy (DN) is a serious diabetes-related complication leading to kidney damage. Cinnamomum tamala (CT), traditionally used in managing diabetes and kidney disorders, has shown potential in treating DN, although its active compounds and mechanisms are not fully understood. This study aims to identify CT's bioactive compounds and explore their therapeutic mechanisms in DN. Active compounds in CT were identified using the Indian Medicinal Plants, Phytochemicals and Therapeutics database, and their potential targets were predicted with PharmMapper. DN-related targets were sourced from GeneCards, and therapeutic targets were identified by intersecting the compound-target and disease-target data. Bioinformatics analyses, including the Kyoto Encyclopedia of Genes and Genomes and Gene Ontology enrichment studies, were performed on these targets. A protein-protein interaction network was constructed using STRING and Cytoscape. Molecular docking and dynamics simulations validated the most promising compound-target interactions. Six active compounds in CT were identified, along with 347 potential therapeutic targets, of which 70 were DN-relevant. Key targets like MMP9, EGFR, and AKT1 were highlighted, and the PPAR and PI3K-AKT signaling pathways were identified as the primary mechanisms through which CT may treat DN. CT shows promise in treating DN by modulating key pathways related to cellular development, inflammation, and metabolism.

Altered Metabolites in Hepatocellular Carcinoma (HCC) Paving the Road for Metabolomics Signature and Biomarkers for Early Diagnosis of HCC

Globally, hepatocellular carcinoma (HCC) is one of the most commonly encountered cancers. Because the current early diagnostic tests for HCC are not very sensitive, most cases of the disease are discovered late when it is in its terminal stage. Cellular metabolism changes during carcinogenesis to enable cancer cells to adapt to the hypoxic milieu, boost anabolic synthesis, promote survival, and evade apoptotic death signals. Omic techniques represent a breakthrough in the field of diagnostic technology. For example, Metabolomics analysis could be used to identify these metabolite alterations. Understanding the metabolic alterations linked to HCC is crucial for improving high-risk patients' surveillance and understanding the illness's biology. This review highlights the metabolic alterations linked to energy production in cancer cells, as well as the significantly altered metabolites and pathways associated with hepatocarcinogenesis, including acylcarnitines (ACs), amino acids, proteins, lipids, carbohydrates, glucose, and lactate, which reflect the anabolic and catabolic changes occurring in these cells. Additionally, it discusses the clinical implications of recent metabolomics that may serve as potential biomarkers for early diagnosis and monitoring of the progression of HCC.

Overlapping group between non-alcoholic fatty liver disease and metabolic associated fatty liver disease better for liver research

AIMS

Metabolic associated fatty liver disease (MAFLD) was proposed to replace "non-alcoholic fatty liver disease (NAFLD) with new diagnostic criteria." The group meeting these two diagnostic criteria is called "Overlapping Fatty Liver Disease (FLD)." Its clinical characteristics remain unknown.

METHODS

This study included participants from the Taiwan Bio-Bank database, where NAFLD was defined as hepatic steatosis in liver ultrasound, with exclusion of other known chronic liver diseases. MAFLD was defined as the presence of hepatic steatosis plus metabolic dysfunction, defined as having any of following three criteria: overweight/obesity, type 2 diabetes mellitus (DM), or ≥2 metabolic risk abnormalities in lean/normal weight subjects. According to these two diagnostic criteria, three groups were identified: "overlapping FLD", "NAFLD alone", and "MAFLD alone." NAFLD fibrosis score (NFS) >0.675 was defined as advanced liver fibrosis.

RESULTS

Eight thousand thirty-eight NAFLD participants (age 55.86 ± 10.12; males 41.07%) were included in the final analysis. Of them, "overlapping FLD" was diagnosed in 7377 (91.8%) and "NAFLD alone" in 661 (8.2%) participants. "Overlapping FLD" patients were older and had a higher percentage of male, worse metabolic profiles, higher NFS, and the percentage of carotid plaques was higher than those with "NAFLD alone." Multivariate analysis showed age, hypertension, DM, and BMI were positively associated with advanced liver fibrosis in "overlapping FLD" patients.

CONCLUSIONS

"Overlapping FLD" is better for liver research due to identifying a high-risk population among NAFLD patients. NAFLD definition introduces the heterogeneity through "NAFLD alone" group and MAFLD criteria overcome this limitation.

Body Composition in Patients With Metabolic Dysfunction-associated Steatotic Liver Disease: Impact of Body Surface Area

BACKGROUND/AIM

To examine the relationship between the body surface area (BSA) and body composition in patients with metabolic dysfunction-associated steatotic liver disease (MASLD, 2,141 men and 986 women).

MATERIALS AND METHODS

BSA and body composition parameters were examined.

RESULTS

The median body mass index (BMI) was 25.0 kg/m2 for both men and women (p=0.7754). The median body surface area (BSA) was 1.854 m2 for men and 1.618 m2 for women (p<0.0001). In men, the median fat mass was 17.7 kg, whereas in women, it was 22.1 kg (p<0.0001). Additionally, the median fat-free mass was 55.4 kg in men and 39.3 kg in women (p<0.0001).). In male cases, BSA significantly correlated with fat mass (r=0.82, p<0.0001) and fat-free mass (r=0.95, p<0.0001). In female cases, BSA significantly correlated with fat mass (r=0.87, p<0.0001) and fat-free mass (r=0.94, p<0.0001).

CONCLUSION

BSA could be a useful marker for the estimation of body composition in patients with MASLD.

A prospective study on the prevalence of at-risk MASH in patients with type 2 diabetes mellitus in the United States

BACKGROUND

There are limited data on the prevalence and treatment of at-risk metabolic dysfunction-associated steatohepatitis (MASH) among patients with type 2 diabetes (T2DM) in the United States.

AIM

To estimate the prevalence of at-risk MASH in a prospectively recruited cohort of adults with T2DM using new nomenclature endorsed by multiple societies.

METHODS

This prospective study enrolled adults aged ≥50 with T2DM from primary care and endocrinology clinics in southern California from 2016 to 2023. Metabolic dysfunction-associated steatotic liver disease (MASLD) was defined by an magnetic resonance imaging proton density fat fraction ≥5% and at least one metabolic risk factor without any other chronic liver disease or secondary cause for hepatic steatosis.

RESULTS

We included 530 adult patients with T2DM. The mean (±SD) age and body mass index (BMI) were 64.4 (±8.1) years and 31.5 (±6.1) kg/m2, respectively. Among patients with T2DM, the prevalence of MASLD, at-risk MASH and cirrhosis was 69.6%, 13.6% and 6.8%, respectively. Among patients with co-existing T2DM and obesity, the prevalence of MASLD, at-risk MASH and cirrhosis was 77.8%, 15.9% and 9.0%, respectively, and was higher than in participants without obesity (p < 0.0001, 0.0543 and 0.0128, respectively).

CONCLUSION

Among adults aged ≥50 years with T2DM, the prevalence of MASLD, at-risk MASH and cirrhosis is high, posing a significant risk for liver-related morbidity and mortality. Approximately 14% of patients with T2DM may be candidates for pharmacologic therapies specific to MASH-related fibrosis.

Cardiometabolic risk factors in MASLD patients with HCC: the other side of the coin

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) constitutes the commonest cause of chronic liver disorder worldwide, whereby affecting around one third of the global population. This clinical condition may evolve into Metabolic Dysfunction-Associated Steatohepatitis (MASH), fibrosis, cirrhosis and hepatocellular carcinoma (HCC), in a predisposed subgroup of patients. The complex pathogenesis of MASLD is severely entangled with obesity, dyslipidemia and type 2 diabetes (T2D), so far so nutritional and lifestyle recommendations may be crucial in influencing the risk of HCC and modifying its prognosis. However, the causative association between HCC onset and the presence of metabolic comorbidities is not completely clarified. Therefore, the present review aimed to summarize the main literature findings that correlate the presence of inherited or acquired hyperlipidemia and metabolic risk factors with the increased predisposition towards liver cancer in MASLD patients. Here, we gathered the evidence underlining the relationship between circulating/hepatic lipids, cardiovascular events, metabolic comorbidities and hepatocarcinogenesis. In addition, we reported previous studies supporting the impact of triglyceride and/or cholesterol accumulation in generating aberrancies in the intracellular membranes of organelles, oxidative stress, ATP depletion and hepatocyte degeneration, influencing the risk of HCC and its response to therapeutic approaches. Finally, our pursuit was to emphasize the link between HCC and the presence of cardiometabolic abnormalities in our large cohort of histologically-characterized patients affected by MASLD (n=1538), of whom 86 had MASLD-HCC by including unpublished data.

Chinese herbal medicine decreases incidence of hepatocellular carcinoma in diabetes mellitus patients with regular insulin management

BACKGROUND

Type 2 diabetes mellitus (DM) is an independent risk factor for hepatocellular carcinoma (HCC), while insulin is a potent mitogen. Identifying a new therapeutic modality for preventing insulin users from developing HCC is a critical goal for researchers.

AIM

To investigate whether regular herbal medicine use can decrease HCC risk in DM patients with regular insulin control.

METHODS

We used data acquired from the Taiwanese National Health Insurance research database between 2000 and 2017. We identified patients with DM who were prescribed insulin for > 3 months. The herb user group was further defined as patients prescribed herbal medication for DM for > 3 months per annum during follow-up. We matched the herb users to nonusers at a 1:3 ratio according to age, sex, comorbidities and index year by propensity score matching. We analyzed HCC incidence, HCC survival rates, and the herbal prescriptions involved.

RESULTS

We initially enrolled 657144 DM patients with regular insulin use from 2000 to 2017. Among these, 46849 patients had used a herbal treatment for DM, and 140547 patients were included as the matched control group. The baseline variables were similar between the herb users and nonusers. DM patients with regular herb use had a 12% decreased risk of HCC compared with the control group [adjusted hazard ratio (aHR) = 0.88, 95%CI = 0.80-0.97]. The cumulative incidence of HCC in the herb users was significantly lower than that of the nonusers. Patients with a herb use of > 5 years cumulatively exhibited a protective effect against development of HCC (aHR = 0.82, P < 0.05). Of patients who developed HCC, herb users exhibited a longer survival time than nonusers (aHR = 0.78, P = 0.0001). Additionally, we report the top 10 herbs and formulas in prescriptions and summarize the potential pharmacological effects of the constituents. Our analysis indicated that Astragalus propinquus (Huang Qi) plus Salvia miltiorrhiza Bunge (Dan Shen), and Astragalus propinquus (Huang Qi) plus Trichosanthes kirilowii Maxim. (Tian Hua Fen) were the most frequent combination of single herbs. Meanwhile, Ji Sheng Shen Qi Wan plus Dan Shen was the most frequent combination of herbs and formulas.

CONCLUSION

This large-scale retrospective cohort study reveals that herbal medicine may decrease HCC risk by 12% in DM patients with regular insulin use.

Treatment Patterns and Recommendations for Improving the Management of Hepatocellular Carcinoma in Saudi Arabia

Hepatocellular carcinoma (HCC) is the sixth most common type of cancer in the world associated with high morbidity and mortality. Despite being a significant healthcare burden there is limited information on the unmet needs and current treatment practices for intermediate and advanced-stage HCC in Saudi Arabia. This article analyzes the gaps and provides expert consensus on the management strategies for unresectable HCC in Saudi Arabia. A pre-meeting online questionnaire, comprising 20 objective questions about the treatment landscape and diagnosis of HCC in Saudi Arabia, was distributed to experts in the field of HCC management. An advisory board meeting including a panel of 13 experts was held in September 2022 where the responses to the survey questionnaire were reviewed and discussed. The survey results and experts' discussion highlighted the growing incidence of liver cancer in Saudi Arabia. HCC comprised the majority of all liver cancer cases due to rising rates of chronic viral infections and lifestyle-related risk factors. Most physicians in Saudi Arabia follow the Barcelona Clinic Liver Cancer guidelines as a prognostic tool for the detection and staging of patients with HCC. Most of the patients with HCC in Saudi Arabia are diagnosed in the intermediate or advanced stages with poor prognoses and limited therapeutic options. Establishing evidence-based surveillance techniques, a multidisciplinary approach to diagnosis, and better accessibility of treatment options is vital for the management of HCC in Saudi Arabia.

Unlocking Colchicine's Untapped Potential: A Paradigm Shift in Hepatocellular Carcinoma Prevention

Background: Liver cancer and notably hepatocellular carcinoma (HCC), results in significantly high mortality rates worldwide. Chronic hepatitis and fatty liver, recognized precursors, underscore the imperative need for effective preventive strategies. This study explores colchicine, traditionally acknowledged for its anti-inflammatory properties and investigates its potential in liver cancer prevention. Methods: Utilizing the iHi Data Platform of China Medical University Hospital, Taiwan, this study analyzed two decades of medical data, incorporating 10,353 patients each in the Colchicine and Non-Colchicine cohorts, to investigate the association between colchicine use and liver cancer risk. Results: The study identified that colchicine users exhibited a 19% reduction in liver cancer risk, with a multivariable-adjusted odds ratio of 0.81 after accounting for confounding variables. Additionally, the influence of gender and comorbidities like diabetes mellitus on liver cancer risk was identified, corroborating the existing literature. A notable finding was that the prolonged use of colchicine was associated with improved outcomes, indicating a potential dose-response relationship. Conclusions: This study proposes a potential new role for colchicine in liver cancer prevention, extending beyond its established anti-inflammatory applications. While the findings are promising, further research is essential to validate these results. This research may serve as a foundation for future studies, aiming to further explore colchicine's role via clinical trials and in-depth investigations, potentially impacting preventive strategies for liver cancer.

Corrected and republished from: Metabolic associated liver disease

Alcohol consumption (AC) and metabolic syndrome (MS) represent the first cause of liver disease, hepatocellular carcinoma and liver transplantation. The habit of consuming alcoholic beverages and the presence of MS and non-alcoholic fatty liver disease (NAFLD) often coexist in the same patient. The histoclinical boundaries between alcohol related liver disease (ALD) and NAFLD are often not well defined. The co-presence of AC and MS increases the risk of hepatic and extra-hepatic disease. The terminological evolution from NAFLD to metabolic associated fatty liver disease (MAFLD) is certainly a useful advance. However, it is known that the appearance of liver fibrosis increases oncologic and cardiovascular disease risk, which in the case of cirrhosis can be present even in the absence of steatosis and that the mechanisms of fibrogenesis can act independently of the presence of steatosis/steatohepatitis. For this reason, as already stated recently, a further terminological evolution can be hypothesized. This article was originally published with mistakes in the text. The new corrected citable version appears below.

PD-L1 is Fascinating but IDO Needs Attention in Non-HCV and Non-HBV-Associated Hepatocellular Carcinoma Patients

Background/Aim

Hepatocellular carcinoma (HCC) is one of the most common forms of liver cancer that is modulated by the immune system. Programmed cell death ligand-1 (PD-L1) has emerged as a novel therapeutic target in various cancers. Indoleamine 2,3-dioxygenase (IDO) is an immunosuppressive enzyme that is associated with poor prognoses in various cancer types. The aim of this study was to investigate the PD-L1 expression, and clinicopathological features of non-HCV and non-HBV-associated HCC patients, including IDO expression.

Patients and Methods

In this study, immunohistochemical analysis was performed to analyze the expression of PD-L1 and IDO. Formalin-fixed paraffin-embedded HCC tumor tissues (n=50) were obtained from the pathology department, at Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH&RC) in Lahore, Pakistan between 2005 and 2022. All the patients were HBV and HCV negative. Furthermore, it was a rare group of patients with no previous history of any viral hepatitis. In addition, for categorical and continuous variables chi-square or Fisher exact test and Mann-Whitney U-test was performed.

Results

Of 50 tissue specimens, PD-L1+ was observed in 21 [high: 12 (24%), low: 9 (18%)] and PD-L1- was observed in 29 HCC patients. IDO+ was observed in all 50 specimens [high: 42 (84%), low: 8 (16%)]. Additionally, both PD-L1 and IDO had high expression in 11 (22%) patients. While both PD-L1 and IDO had low expression in 2 (4%) patients. Furthermore, in IDO+/PD-L1- group, 20 (69%) out of 29 patients died while in the IDO+/PD-L1+ group, 9 (43%) out of 21 patients died.

Conclusion

Evaluation of IDO and PD-L1 expression may add therapeutic advantage in non-HCV and non-HBV-associated HCC patients that overexpress IDO. Further validation in a larger cohort is warranted.

In vivo assessment of the pharmacokinetic interactions between donafenib and dapagliflozin, donafenib and canagliflozin in rats

Donafenib (DONA), a deuterium derivative of sorafenib, is used for advanced hepatocellular carcinoma (HCC). Dapagliflozin (DAPA) and canagliflozin (CANA) are sodium-glucose co-transporter 2 (SGLT2) inhibitors used for T2DM, which is frequently comorbid with HCC. Three drugs are substrates of UGT1A9 isoenzyme. This study aimed to evaluate donafenib-dapagliflozin and donafenib-canagliflozin pharmacokinetic interactions and explore the potential mechanisms. Rats were divided into seven groups (n = 6) that received donafenib (1), dapagliflozin (2), canagliflozin (3), dapagliflozin and donafenib (4), canagliflozin and donafenib (5), donafenib and dapagliflozin (6), donafenib and canagliflozin (7). The concentrations of drugs were determined by an ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method. The messenger RNA (mRNA) expressions were measured by quantitative RT-PCR. Multiple doses of dapagliflozin caused donafenib maximum plasma concentration (C_max) to increase 37.01%. Canagliflozin increased donafenib C_max 1.77-fold and the area under the plasma concentration-time curves (AUC_0-t and AUC_inf) 1.39- and 1.41-fold, respectively, while reducing the apparent clearance (CL_z) 28.38%. Multiple doses of donafenib increased dapagliflozin AUC_0-t 1.61-fold, AUC_inf 1.77-fold, whereas its CL_z reduced 40.50%. Furthermore, donafenib caused similar changes in canagliflozin pharmacokinetics. The PCR results demonstrated that dapagliflozin inhibited the mRNA expression of Ugt1a7 in liver and donafenib decreased the expression of Ugt1a7 mRNA in liver and intestine. Increased exposure to these drugs may be due to their metabolism inhibition mediated by Ugt1a7. These pharmacokinetic interactions observed in this study may be of clinical significance, which may help adjust dose properly and avoid toxicity effects in patients with HCC and T2DM.

Does Type 2 Diabetes Increase the Risk of Hepatocellular Carcinoma in Nonalcoholic Fatty Liver Disease Patients? A Systematic Review

Diabetes is associated with different types of cancers of which hepatocellular carcinoma (HCC) is one among them. In a study comparing patients with diabetes to those who do not have diabetes, it was evident that the risk of HCC is found to increase two-fold in diabetic than that in non-diabetic patients. It is clear that carcinogenesis is advanced due to diabetes in the liver by a variety of mechanisms. We searched PubMed and Google Scholar for articles from 2010 to 2021 that have an association between diabetes, nonalcoholic fatty liver disease (NAFLD), and HCC. For the development of HCC, diabetes is likely related at both the molecular and epidemiological levels. Both diabetes mellitus and hepatic malignancy have the worst impact on mankind socioeconomically. There is a significant relationship between diabetes and HCC independent of alcohol consumption and viral hepatitis. It is noteworthy that not only the elderly but also people of all age groups should monitor their hemoglobin A1C levels. Diet restriction and lifestyle modification can reduce the risk of complications like HCC; the increased physical activity itself can have a major influence on health and can manage comorbidities like diabetes, NAFLD, and HCC.

Does maternal low-dose cadmium exposure increase the risk of offspring to develop metabolic syndrome and/or type 2 diabetes?

Cadmium is a hazardous metal with multiple organ toxicity that causes great harm to human health. Cadmium enters the human body through occupational exposure, diet, drinking water, breathing, and smoking. Cadmium accumulation in the human body is associated with increased risk of developing obesity, cardiovascular disease, diabetes, and metabolic syndrome (MetS). Cadmium uptake is enhanced during pregnancy and can cross the placenta affecting placental development and function. Subsequently, cadmium can pass to fetus, gathering in multiple organs such as the liver and pancreas. Early-life cadmium exposure can induce hepatic oxidative stress and pancreatic β-cell dysfunction, resulting in insulin resistance and glucose metabolic dyshomeostasis in the offspring. Prenatal exposure to cadmium is also associated with increasing epigenetic effects on the offspring's multi-organ functions. However, whether and how maternal exposure to low-dose cadmium impacts the risks of developing type 2 diabetes (T2D) in the young and/or adult offspring remains unclear. This review collected available data to address the current evidence for the potential role of cadmium exposure, leading to insulin resistance and the development of T2D in offspring. However, this review reveals that underlying mechanisms linking prenatal cadmium exposure during pregnancy with T2D in offspring remain to be adequately investigated.

Metabolism as a New Avenue for Hepatocellular Carcinoma Therapy

Hepatocellular carcinoma is today the sixth leading cause of cancer-related death worldwide, despite the decreased incidence of chronic hepatitis infections. This is due to the increased diffusion of metabolic diseases such as the metabolic syndrome, diabetes, obesity, and nonalcoholic steatohepatitis (NASH). The current protein kinase inhibitor therapies in HCC are very aggressive and not curative. From this perspective, a shift in strategy toward metabolic therapies may represent a promising option. Here, we review current knowledge on metabolic dysregulation in HCC and therapeutic approaches targeting metabolic pathways. We also propose a multi-target metabolic approach as a possible new option in HCC pharmacology.

Exploring genetic influences on adverse outcome pathways using heuristic simulation and graph data science

Adverse outcome pathways provide a powerful tool for understanding the biological signaling cascades that lead to disease outcomes following toxicity. The framework outlines downstream responses known as key events, culminating in a clinically significant adverse outcome as a final result of the toxic exposure. Here we use the AOP framework combined with artificial intelligence methods to gain novel insights into genetic mechanisms that underlie toxicity-mediated adverse health outcomes. Specifically, we focus on liver cancer as a case study with diverse underlying mechanisms that are clinically significant. Our approach uses two complementary AI techniques: Generative modeling via automated machine learning and genetic algorithms, and graph machine learning. We used data from the US Environmental Protection Agency's Adverse Outcome Pathway Database (AOP-DB; aopdb.epa.gov) and the UK Biobank's genetic data repository. We use the AOP-DB to extract disease-specific AOPs and build graph neural networks used in our final analyses. We use the UK Biobank to retrieve real-world genotype and phenotype data, where genotypes are based on single nucleotide polymorphism data extracted from the AOP-DB, and phenotypes are case/control cohorts for the disease of interest (liver cancer) corresponding to those adverse outcome pathways. We also use propensity score matching to appropriately sample based on important covariates (demographics, comorbidities, and social deprivation indices) and to balance the case and control populations in our machine language training/testing datasets. Finally, we describe a novel putative risk factor for LC that depends on genetic variation in both the aryl-hydrocarbon receptor (AHR) and ATP binding cassette subfamily B member 11 (ABCB11) genes.

Screening and interventions to prevent nonalcoholic fatty liver disease/nonalcoholic steatohepatitis-associated hepatocellular carcinoma

Liver cancer is the sixth most commonly diagnosed cancer worldwide, with hepatocellular carcinoma (HCC) comprising most cases. Besides hepatitis B and C viral infections, heavy alcohol use, and nonalcoholic steatohepatitis (NASH)-associated advanced fibrosis/cirrhosis, several other risk factors for HCC have been identified (i.e. old age, obesity, insulin resistance, type 2 diabetes). These might in fact partially explain the occurrence of HCC in non-cirrhotic patients without viral infection. HCC surveillance through effective screening programs is still an unmet need for many nonalcoholic fatty liver disease (NAFLD) patients, and identification of pre-cirrhotic individuals who progress to HCC represents a substantial challenge in clinical practice at the moment. Patients with NASH-cirrhosis should undergo systematic HCC surveillance, while this might be considered in patients with advanced fibrosis based on individual risk assessment. In this context, interventions that potentially prevent NAFLD/ NASH-associated HCC are needed. This paper provided an overview of evidence related to lifestyle changes (i.e. weight loss, physical exercise, adherence to healthy dietary patterns, intake of certain dietary components, etc.) and pharmacological interventions that might play a protective role by targeting the underlying causative factors and pathogenetic mechanisms. However, well-designed prospective studies specifically dedicated to NAFLD/NASH patients are still needed to clarify the relationship with HCC risk.

Interventional nanotheranostics in hepatocellular carcinoma

Interventional nanotheranostics is a system of drug delivery that does a dual function; along with the therapeutic action, it also does have diagnostic features. This method helps in early detection, targeted delivery, and the least chances of damage to surrounding tissue. It ensures the highest efficiency for the management of the disease. Imaging is the near future for the quickest and most accurate detection of disease. After combing both effective measures, it ensures the most meticulous drug delivery system. Nanoparticles such as Gold NPs, Carbon NPs, Silicon NPS, etc. The article emphasizes on effect of this delivery system in the treatment of Hepatocellular Carcinoma. It is one of the widely spreading diseases and theranostics is trying to make the scenario better. The review suggests the pitfall of the current system and how theranostics can help. It describes the mechanism used to generate its effect and believes that interventional nanotheranostics do have a future with rainbow color. The article also describes the current hindrance to the flourishing of this miraculous technology.

Metabolic associated liver disease

In real practice the patient with liver disease is often the carrier of multiple etiological factors such as metabolic syndrome (MS) and alcohol consumption (AC). Their copresence is often underestimated and AC is not adequately studied. Traditionally to diagnose non-alcoholic fatty liver disease (NAFLD), AC must not exceed 30 gr for men and 20 gr for women per day. This limit should still be reduced, especially in relation to the AC and fibrogenesis ratio and also frequent misestimation of AC or unrecognized MS may underestimate multi caused liver injury. AC is a contributing cause of MS and alcoholic and non-alcoholic liver disease have a substantially overlapping histopathological picture. Moreover, AC and MS are cause and contributing cause of extra-hepatic morbidity and mortality. It can be concluded that the possible simplification of terminology at metabolic associated liver disease (MALD) makes clinical activity more usable and immediate, facilitates better communication and cooperation between scientific societies and specialists who apparently deal with different medical sectors, facilitates early identification of related hepatic and extra-hepatic pathology, allows to "see the person in a unitary way," to create more streamlined care pathways, to reduce the hospitalization rate with relative cost-benefit advantage and to create unitary prevention and health promotion policies.

Plasma Insulin/Erythrocytic Aldose Reductase Ratio as a Predictor for Hepatocellular Carcinoma among Type II Diabetics and Hepatitis C Virus-infected Patients

BACKGROUND

Hepatocellular carcinoma (HCC) is a possible oncogenic progression during persistent hepatitis C-infection +/- type II diabetes mellitus (DM). We aim to investigate the plasma insulin, erythrocytic aldose reductase (AR) and sorbitol dehydrogenase (SDH) as possible predictive tools for HCC in hepatitis C-infected patients (HCV) +/- DM. Erythrocytes (RBCs) were adopted as a possible vehicle for pre-malignant variations being of short life span.    Methods: The study included 20 healthy control and 100 patients of 48-64 years old, divided into 5 equal groups as; type II DM, HCC, HCC with DM, DM- HCV infected and non-DM HCV infected. Plasma levels of AFP and insulin were measured.

RESULTS

It showed an elevated AR, significant reduction of SDH in RBCs and plasma of DM patients. These values were greatly elevated among HCV, HCC, diabetic HCV, and diabetic HCC patients. All DM patients showed elevated insulin levels than normoglycemic controls.

CONCLUSION

The study substantiated the use of RBCs as a vehicle for early diagnostic markers better than plasma. We recommend the use of insulin/ erythrocytic AR ratio as a new laboratory marker for predicting HCC among type II diabetics or non-treated HCV-infected patients with control insulin/ erythrocytic AR ratio by each laboratory.

Effect of diabetes medications and glycemic control on risk of hepatocellular cancer in patients with nonalcoholic fatty liver disease

BACKGROUND AND AIMS

In patients with NAFLD, those with type 2 diabetes mellitus (DM) have a high risk of progression to HCC. However, the determinants of HCC risk in these patients remain unclear.

APPROACH AND RESULTS

We assembled a retrospective cohort of patients with NAFLD and DM diagnosed at 130 facilities in the Veterans Administration between 1/1/2004 and 12/31/2008. We followed patients from the date of NAFLD diagnosis to HCC, death, or 12/31/2018. We used landmark Cox proportional hazards models to determine the effects of anti-DM medications (metformin, insulin, sulfonylureas) and glycemic control (percent of follow-up time with hemoglobin A1c < 7%) on the risk of HCC while adjusting for demographics and other metabolic traits (hypertension, obesity, dyslipidemia). We identified 85,963 patients with NAFLD and DM. In total, 524 patients developed HCC during a mean of 10.3 years of follow-up. Most common treatments were metformin monotherapy (19.7%), metformin-sulfonylureas (19.6%), insulin (9.3%), and sulfonylureas monotherapy (13.6%). Compared with no medication, metformin was associated with 20% lower risk of HCC (HR, 0.80; 95% CI, 0.93-0.98). Insulin had no effect on HCC risk (HR, 1.02; 95% CI, 0.85-1.22; p = 0.85). Insulin in combination with other oral medications was associated with a 1.6 to 1.7-fold higher risk of HCC. Adequate glycemic control was associated with a 31% lower risk of HCC (HR, 0.69; 95% CI, 0.62-0.78).

CONCLUSIONS

In this large cohort of patients with NAFLD and DM, use of metformin was associated with a reduced risk of HCC, whereas use of combination therapy was associated with increased risk. Glycemic control can serve as a biomarker for HCC risk stratification in patients with NAFLD and diabetes.

Risk Associations of Glycemic Burden and Obesity With Liver Cancer-A 10-Year Analysis of 15,280 Patients With Type 2 Diabetes

Liver is a major site for glucose metabolism. Patients with type 2 diabetes (T2D) and obesity have increased risk of liver cancer. We explored the association of glycemic burden (GB) and obesity with liver cancer in T2D in the prospective Hong Kong Diabetes Register (1995-2019). We calculated GB using the area under the curve above hemoglobin A1c (HbA1c) of 5.7% and defined obesity as body mass index (BMI) ≥ 25 kg/m2 . We used Cox proportional hazards models to evaluate the association between GB and liver cancer. We included 15,280 patients with at least 10 years of disease duration before liver cancer occurred or censor date, ≥3 years of observation, and ≥5 HbA1c measurements (64% male, age: 58.23 ± 12.47 years, HbA1c: 7.60 ± 1.65%, BMI: 25.58 ± 4.10 kg/m2 ). We excluded 3 years of HbA1c values before liver cancer to avoid reverse causality. Every 1-SD increase in GB was associated with an adjusted hazard ratio (aHR) of liver cancer of 1.22 (95% confidence interval [CI]: 1.01-1.47). The top GB quartile group (range: >2.41) had aHR of 1.78 (1.01-3.13) versus the lowest quartile group (0-1.19). The aHRs for each SD increase in GB were 1.34 (1.05, 1.70) in the obese group and 1.12 (0.81-1.53) in the nonobese group, but no interaction (Pinteraction  = 0.120). When stratified by GB median (1.69 [1.13, 2.43]) and obesity, obese patients with high GB had the highest aHR of 2.51 (1.44-4.37) for liver cancer versus the nonobese group with low GB, but no interaction (Pinteraction  = 0.071). Subgroup analysis of patients with available hepatitis B surface antigen status (n = 9,248) yielded similar results. Conclusion: Our results emphasized the importance of glycemic and weight control for reducing the risk of liver cancer in T2D.

Pyruvate Dehydrogenase A1 Phosphorylated by Insulin Associates with Pyruvate Kinase M2 and Induces LINC00273 through Histone Acetylation

Insulin potently promotes cell proliferation and anabolic metabolism along with a reduction in blood glucose levels. Pyruvate dehydrogenase (PDH) plays a pivotal role in glucose metabolism. Insulin increase PDH activity by attenuating phosphorylated Ser293 PDH E1α (p-PDHA1) in normal liver tissue. In contrast to normal hepatocytes, insulin enhanced p-PDHA1 level and induced proliferation of hepatocellular carcinoma HepG2 cells. Here, we attempted to find a novel function of p-PDHA1 in tumorigenesis upon insulin stimulation. We found that p-Ser293 E1α, but not the E2 or E3 subunit of pyruvate dehydrogenase complex (PDC), co-immunoprecipitated with pyruvate kinase M2 (PKM2) upon insulin. Of note, the p-PDHA1 along with PKM2 translocated to the nucleus. The p-PDHA1/PKM2 complex was associated with the promoter of long intergenic non-protein coding (LINC) 00273 gene (LINC00273) and recruited p300 histone acetyl transferase (HAT) and ATP citrate lyase (ACL), leading to histone acetylation. Consequently, the level of transcription factor ZEB1, an epithelial–mesenchymal transition (EMT) marker, was promoted through increased levels of LINC00273, resulting in cell migration upon insulin. p-PDHA1, along with PKM2, may be crucial for transcriptional regulation of specific genes through epigenetic regulation upon insulin in hepatocarcinoma cells.

Impact of diabetes mellitus on the long-term prognosis of patients with hepatocellular carcinoma after hepatectomy

BACKGROUND

The impact of diabetes mellitus (DM) on the survival of patients with hepatocellular carcinoma (HCC) is still unclear. The present study aims to draw a firm conclusion in terms of evaluating the impact of DM on the prognosis of HCC after hepatectomy.

METHODS

The pattern of recurrence for HCC was often stratified into early-stage (<2 years) and late-stage (≥2 years) recurrence. Because the early-stage recurrence was mainly attributed to aggressive tumor pathological characteristics, patients who recurrence or die within 2 years were excluded. Cumulative overall survival (OS) and recurrence-free survival (RFS) were determined by the method of Kaplan-Meier, and the independent risk factors of OS/RFS were determined by Cox regression analysis.

RESULTS

A total of 426 patients were eventually included. The 3- and 5-year OS in patients with and without DM was 83.7%, 55.1%; and 90.9%, 77.4%, respectively. Multivariate analysis showed that DM was an independent risk factor for OS (HR 1.166, 95% CI 1.056-2.036, P = 0.022) and RFS (HR 1.365, 95% CI 1.043-1.787, P = 0.023).

CONCLUSION

DM is an independent risk factor for long-term prognosis in patients with HCC. Patients with DM after hepatectomy for HCC, thus, need to actively control DM and closer follow-up.

HSD17B13 and other liver fat-modulating genes predict development of hepatocellular carcinoma among HCV-positive cirrhotics with and without viral clearance after DAA treatment

BACKGROUND

Genetic predisposition to accumulate liver fat (expressed by a polygenic risk score, GRS, based on the number of at-risk alleles of PNPLA3, TM6SF2, MBOAT7 and GCKR) may influence the probability of developing hepatocellular carcinoma (HCC) after hepatitis C treatment. Whether this holds true taking into account carriage of the HSD17B13:TA splice variant, also affecting lipogenesis, and achievement of viral clearance (SVR), is unknown.

METHODS

PNPLA3, TM6SF2, MBOAT7, GCKR and HSD17B13 variants were determined in a cohort of 328 cirrhotic patients free of HCC before starting treatment with direct acting antivirals (DAA).

RESULTS

SVR in the study cohort was 96%. At the end of follow-up, N = 21 patients had been diagnosed an HCC; none of the genes included in the GRS was individually associated with HCC development. However, in a Cox proportional hazards model, a GRS > 0.457 predicted HCC independently of sex, diabetes, albumin, INR and FIB4. The fit of the model improved adding treatment outcome and carriage of the HSD17B13:TA splice variant, with sex, GRS > 0.457, HSD17B13:TA splice variant and failure to achieve an SVR (hazard ratio = 6.75, 4.24, 0.24 and 7.7, respectively) being independent predictors of HCC.

CONCLUSION

Our findings confirm that genes modulating liver fat and lipogenesis are important risk factors for HCC development among cirrhotics C treated with DAA.

Risk factors of hepatocellular carcinoma in type 2 diabetes patients: A two-centre study in a developing country

Type 2 diabetes mellitus (T2DM) is increasingly known as a risk factor of hepatocellular carcinoma (HCC). In this study, we determined the risk factors associated with HCC in T2DM patients. This was a matched case-control study conducted at two hepatobiliary referral centres in a developing country. Patients' sociodemographic, clinical, and biochemical characteristics between 1 January 2012 and 30 June 2018 were extracted from the electronic medical records and analysed using multivariate logistic regression analysis. A total of 212 case-control pairs were included. Significant risk factors included Chinese and Malay ethnicities that interacted with viral hepatitis (adjusted odds ratio [AOR] = 11.77, 95% confidence interval [CI]: 1.39-99.79) and (AOR = 37.94, 95% CI: 3.92-367.61) respectively, weight loss (AOR = 5.28, 95% CI: 2.29-12.19), abdominal pain/ discomfort (AOR = 6.73, 95% CI: 3.34-13.34), alcohol (AOR = 4.08, 95% CI: 1.81-9.22), fatty liver (AOR = 3.29, 95% CI: 1.40-7.76), low platelet (AOR = 4.03, 95% CI:1.90-8.55), raised alanine transaminase (AOR = 2.11, 95% CI: 1.16-3.86). and alkaline phosphatase (ALP) levels (AOR = 2.17, 95% CI: 1.17-4.00). Statins reduced the risk of HCC by 63% (AOR = 0.37, 95% CI: 0.21-0.65). The identification of these factors aids the risk stratification for HCC among T2DM patients for early detection and decision-making in patient management in the primary care setting.

External validation of the Toronto hepatocellular carcinoma risk index in a Swedish population

Background & Aims

The Toronto hepatocellular carcinoma (HCC) risk index (THRI) is a predictive model to determine the risk of HCC in patients with cirrhosis. This study aimed to externally validate the THRI in a Swedish setting to investigate whether it could identify patients not requiring HCC surveillance.

Methods

From 2004-2017, 2,491 patients with cirrhosis at the Karolinska University Hospital were evaluated. Patients were classified into low-, intermediate- and high-risk groups for future HCC according to the THRI. Harrell’s C-index, calibration-in-the-large, calibration slope and goodness-of-fit estimates were calculated to assess model discrimination and calibration. Cox proportional hazards regression was used to determine the risk of HCC.

Results

Most patients were male (n = 1,638, 66%). The most common etiologies of cirrhosis were steatohepatitis (n = 1,182, 48%) followed by viral hepatitis (n = 987, 40%). In all, 131 patients (5.3%) were designated as low risk for HCC. Harrell’s C-index was 0.69. Calibration-in-the-large (0.11), calibration slope (1.24, not different from 1, p = 0.66) and goodness-of-fit showed good model calibration. Patients in the high-risk group had a 7.1-fold (95% CI 2.9–17.2) higher risk of HCC and patients in the intermediate-risk group had a 2.5-fold (95% CI 1.0–6.3) higher risk compared to the low-risk group.

Conclusions

In a Swedish setting, the THRI could differentiate between low- and high-risk of HCC development. However, because the low-risk group was relatively small (5.3%), the clinical applicability of the THRI could be limited.

Lay summary

The Toronto hepatocellular carcinoma (HCC) risk index (THRI) is a novel prediction model used to stratify patients with cirrhosis based on future risk of HCC. In this study, the THRI was validated in an external cohort using the TRIPOD guidance. Few patients were identified as low-risk, and the THRI had a modest discriminative ability, limiting its clinical applicability.

•

The THRI is a simple and non-invasive method to estimate 5- and 10-year HCC risk.

•

This was the largest validation of the THRI to date.

•

The THRI had a modest discriminative ability and was well-calibrated.

•

However, the THRI could only identify few patients at low risk of HCC, limiting its clinical use.

Inhibitory effects of Humulus japonicus extract against hepatic injury in a diabetic rat model

Chronic diabetes mellitus (DM) can cause liver dysfunction and other complications. As Humulus japonicus is known to have anti-inflammatory and antioxidative effects, we sought to evaluate the hepatoprotective effect of H. japonicus extract (HJE) on a DM model. HJE reduced aspartate aminotransferase, alanine aminotransferase, and direct bilirubin levels and restored albumin activities relative to those found in the DM model. The abnormal levels of triglyceride, total cholesterol, high-density lipoprotein, and low-density lipoprotein in DM returned to normal levels after HJE treatment. DM-induced inflammation of the liver was ameliorated by HJE through reduction of tumor necrosis factor-α, interleukin-1β, and cyclooxygenase-2 levels. HJE treatment downregulated malondialdehyde levels that were increased by DM. However, the downregulated superoxide dismutase and glutathione levels in DM were increased by HJE. Histological studies showed that HJE improves the liver tissue damage caused by DM. Collectively, our findings suggest that HJE may improve liver damage in DM and exhibit an inhibitory effect on hepatic injury through its anti-inflammatory and antioxidative actions.

Gestational Cd Exposure in the CD-1 Mouse Induces Sex-Specific Hepatic Insulin Insensitivity, Obesity, and Metabolic Syndrome in Adult Female Offspring

There is compelling evidence that developmental exposure to toxic metals increases risk for obesity and obesity-related morbidity including cardiovascular disease and type 2 diabetes. To explore the hypothesis that developmental Cd exposure increases risk of obesity later in life, male, and female CD-1 mice were maternally exposed to 500 ppb CdCl2 in drinking water during a human gestational equivalent period (gestational day 0-postnatal day 10 [GD0-PND10]). Hallmark indicators of metabolic disruption, hepatic steatosis, and metabolic syndrome were evaluated prior to birth through adulthood. Maternal blood Cd levels were similar to those observed in human pregnancy cohorts, and Cd was undetected in adult offspring. There were no observed impacts of exposure on dams or pregnancy-related outcomes. Results of glucose and insulin tolerance testing revealed that Cd exposure impaired offspring glucose homeostasis on PND42. Exposure-related increases in circulating triglycerides and hepatic steatosis were apparent only in females. By PND120, Cd-exposed females were 30% heavier with 700% more perigonadal fat than unexposed control females. There was no evidence of dyslipidemia, steatosis, increased weight gain, nor increased adiposity in Cd-exposed male offspring. Hepatic transcriptome analysis on PND1, PND21, and PND42 revealed evidence for female-specific increases in oxidative stress and mitochondrial dysfunction with significant early disruption of retinoic acid signaling and altered insulin receptor signaling consistent with hepatic insulin sensitivity in adult females. The observed steatosis and metabolic syndrome-like phenotypes resulting from exposure to 500 ppb CdCl2 during the pre- and perinatal period of development equivalent to human gestation indicate that Cd acts developmentally as a sex-specific delayed obesogen.

Cellular protein markers, therapeutics, and drug delivery strategies in the treatment of diabetes-associated liver fibrosis

Liver fibrosis is the excessive accumulation of extracellular matrix due to chronic injuries, such as viral infection, alcohol abuse, high-fat diet, and toxins. Liver fibrosis is reversible before it progresses to cirrhosis and hepatocellular carcinoma. Type 2 diabetes significantly increases the risk of developing various complications including liver diseases. Abundant evidence suggests that type 2 diabetes and liver diseases are bidirectionally associated. Patients with type 2 diabetes experience more severe symptoms and accelerated progression of live diseases. Obesity and insulin resistance resulting from hyperlipidemia and hyperglycemia are regarded as the two major risk factors that link type 2 diabetes and liver fibrosis. This review summarizes possible mechanisms of the association between type 2 diabetes and liver fibrosis. The cellular protein markers that can be used for diagnosis and therapy of type 2 diabetes-associated liver fibrosis are discussed. We also highlight the potential therapeutic agents and their delivery systems that have been investigated for type 2 diabetes-associated liver fibrosis.

Metformin Actions on the Liver: Protection Mechanisms Emerging in Hepatocytes and Immune Cells against NASH-Related HCC

Nonalcoholic fatty liver disease (NAFLD) is strongly linked to the global epidemic of obesity and type 2 diabetes mellitus (T2DM). Notably, NAFLD can progress from the mildest form of simple steatosis to nonalcoholic steatohepatitis (NASH) that increases the risk for hepatocellular carcinoma (HCC), which is a malignancy with a dismal prognosis and rising incidence in the United States and other developed counties, possibly due to the epidemic of NAFLD. Metformin, the first-line drug for T2DM, has been suggested to reduce risks for several types of cancers including HCC and protect against NASH-related HCC, as revealed by epidemical studies on humans and preclinical studies on animal models. This review focuses on the pathogenesis of NASH-related HCC and the mechanisms by which metformin inhibits the initiation and progression of NASH-related HCC. Since the functional role of immune cells in liver homeostasis and pathogenesis is increasingly appreciated in developing anti-cancer therapies on liver malignancies, we discuss both the traditional targets of metformin in hepatocytes and the recently defined effects of metformin on immune cells.

Clinical significance of expression of serum insulin-like growth factor-1 in patients with primary liver cancer and diabetes mellitus

BACKGROUND

Studies have reported that serum insulin like growth factor 1 (IGF-1) levels decrease in patients with primary liver cancer or type 2 diabetes, but there are also reports that serum IGF-1 levels increase in these patients. Whether primary liver cancer and type 2 diabetes have a mutual promotion effect remains unclear. Evaluating the prognostic effect of serum IGF-1 in these patients will provide a theoretical basis for early detection of liver cancer and liver cancer with type 2 diabetes.

AIM

To investigate the IGF-1 expression in patients with hepatocellular carcinoma (HCC) complicated with type 2 diabetes mellitus (DM2).

METHODS

From 2014 to 2018, 80 patients with DM2, 80 patients with HCC, and 80 patients with HCC complicated with DM2 were collected from Xinjiang Hospitals. Serum IGF-1, alpha-fetoprotein (AFP), and carbohydrate antigen 199 (CA199) were measured in all patients.

RESULTS

The three groups had significantly different levels of serum IGF-1, AFP, and CA199. The level of serum IGF-1 was significantly higher in the DM2 group and HCC complicated with DM2 group than in the HCC group (P < 0.05). The levels of serum AFP and CA199 were significantly higher in the HCC group and HCC complicated with DM2 group than in the DM2 group (P < 0.05). The levels of serum IGF-1, AFP, and CA199 in the HCC complicated with DM2 group did not differ significantly among patients with different HCC stages (P > 0.05).

CONCLUSION

The levels of IGF-1 in patients with HCC complicated with DM2 group are higher than those of patients with HCC alone. This finding may be used to guide the early screening of patients with HCC complicated with DM2.

Risk factors for intraocular metastasis of primary liver cancer in diabetic patients: Alpha-fetoprotein and cancer antigen 125

BACKGROUND

In rare instances, primary liver cancer can be associated with intraocular metastasis (IOM).

AIM

To investigate the correlation between a diverse range of clinical characteristics and IOM in diabetic patients with primary liver cancer, and to determine potential risk factors in predicting IOM.

METHODS

We recruited a total of 722 diabetic patients with primary liver cancer. The differences between the IOM and non-intraocular metastasis (NIOM) groups in these patients were assessed using the chi-squared test and Student’s t-test. Binary logistic regression analysis was subsequently used to determine risk factors. Finally, the diagnostic value of IOM in this cohort with primary liver cancer was analyzed by receiver operating characteristic (ROC) curve analysis.

RESULTS

In all, 13 patients had IOM. There were no remarkable intergroup differences with respect to age, sex, histopathological sub-types, or blood biochemical parameters. However, the IOM group had significantly higher alpha-fetoprotein (AFP) and cancer antigen 125 (CA125) values than the NIOM group. Binary logistic regression identified AFP and CA125 to be significant risk factors for IOM in diabetic patients with primary liver cancer. ROC curve analysis showed that the area under the curve values for AFP and CA125 were 0.727 and 0.796, with the cut-off values of 994.20 ng/mL and 120.23 U/mL, respectively. The sensitivity and specificity for AFP were 92.3% and 59.9%, while those for CA125 were 84.6% and 70.1%, respectively.

CONCLUSION

Elevated AFP and CA125 represent significant risk factors for IOM in diabetic patients with primary liver cancer.

Incidence and Survival of Hepatocellular Carcinoma in Type 2 Diabetes Patients with Cirrhosis Who Were Treated with and without Metformin

PURPOSE

To evaluate metformin's benefit on the incidence and survival of hepatocellular carcinoma (HCC) in cirrhosis with type 2 diabetes mellitus (T2DM) patients.

PATIENTS AND METHODS

We conducted a retrospective study from 2006 to 2019. The patients were assigned to metformin exposure if they administered metformin at least 3 months after diagnosis of cirrhosis. The outcomes were incidence and survival of HCC in T2DM with cirrhosis treated with metformin compared with those who were not treated with metformin. For the incidence of HCC, the follow-up time was 5 years after cirrhosis was diagnosed. For the survival of HCC, we censored for vital status in June 2019.

RESULTS

Of 1061 patients, the patients were divided into 719 patients with metformin exposure and 342 in metformin non-exposure. In metformin exposure, 125 patients (17.4%) developed HCC. In metformin non-exposure, 128 patients (37.4%) developed HCC. Metformin exposure had a significantly lower risk of developing HCC in multivariate analysis HR 0.48 (0.36-0.61); P<0.001. For the survival of HCC, 327 patients were recruited. One-hundred and sixty-two patients were in metformin exposure and 165 patients were in metformin non-exposure. Sixty patients (37%) in metformin exposure died, while 84 patients (50.9%) in metformin non-exposure died. The median survival of metformin exposure and metformin non-exposure were 6.9 years and 3.88 years, respectively; P=0.003. In univariate analysis, the metformin exposure was significantly associated with better survival than in the non-exposure group, HR 0.63 (0.45-0.88); P=0.006. No significant difference was observed in multivariate analysis between two groups, HR 1.07 (0.74-1.54); P=0.72.

CONCLUSION

Metformin exposure was associated with a lower incidence of HCC in cirrhosis with T2DM patients and seemed to extend survival. Continuing metformin in patients with cirrhosis with T2DM should be considered if there was no contraindication.

Prognostic roles of diabetes mellitus and hypertension in advanced hepatocellular carcinoma treated with sorafenib

BACKGROUND & AIMS

It remains limited whether diabetes mellitus (DM) and hypertension (HTN) affect the prognosis of advanced hepatocellular carcinoma (HCC) treated with sorafenib. Our study attempted to elucidate the roles of DM/HTN and the effects of diabetes medications among advanced HCC patients receiving sorafenib.

METHODS

From August 2012 to February 2018, 733 advanced HCC patients receiving sorafenib were enrolled at China Medical University, Taichung, Taiwan. According to the presence/absence of DM or HTN, they were divided into four groups: control [DM(-)/HTN(-), n = 353], DM-only [DM(+)/HTN(-), n = 91], HTN-only [DM(-)/HTN(+), n = 184] and DM+HTN groups [DM(+)/HTN(+), n = 105]. Based on the types of diabetes medications, there were three groups among DM patients (the combined cohort of DM-only and DM+HTN groups), including metformin (n = 63), non-metformin oral hypoglycemic agent (OHA) (n = 104) and regular insulin (RI)/neutral protamine hagedorn (NPH) groups (n = 29). We then assessed the survival differences between these groups.

RESULTS

DM-only and DM+HTN groups significantly presented longer overall survival (OS) than control group (control vs. DM-only, 7.70 vs. 11.83 months, p = 0.003; control vs. DM+HTN, 7.70 vs. 11.43 months, p = 0.008). However, there was no significant OS difference between control and HTN-only group (7.70 vs. 8.80 months, p = 0.111). Besides, all groups of DM patients showed significantly longer OS than control group (control vs. metformin, 7.70 vs. 12.60 months, p = 0.011; control vs. non-metformin OHA, 7.70 vs. 10.80 months, p = 0.016; control vs. RI/NPH, 7.70 vs. 15.20 months, p = 0.026).

CONCLUSIONS

Rather than HTN, DM predicts better prognosis in advanced HCC treated with sorafenib. Besides, metformin, non-metformin OHA and RI/NPH are associated with longer survival among DM-related advanced HCC patients receiving sorafenib.

Metformin protects against diabetes-induced heart injury and dunning prostate cancer model

In this study, both diabetes and Dunning prostate cancer were induced for the first time in Copenhagen rats in vivo. Thus, the effects of metformin against heart tissue damage of these rats were investigated by biochemical methods. Dunning prostate cancer was induced in Copenhagen rats using high metastatic MAT-LyLu cells. The rats were divided as follows: Control group: only injected with 0.9% NaCl for 14 days; Diabetic group: only injected single dose of streptozotocin (STZ) (65 mg/kg); Cancer group: subcutaneously (s.c) inoculated with 2 x 10⁴ MAT-LyLu cells only; Diabetic + cancer (DC) group: inoculated with 2 x 10⁴ MAT-LyLu cells and STZ injection, Cancer + metformin (CM) group: injected with metformin for 14 days after Mat-LyLu cells application; Diabetic + cancer + metformin (DCM) group: metformin administered for 14 days together with STZ and Mat-LyLu cells. At the end of the experimental period, heart tissues were taken. Reduced glutathione and total antioxidant status levels in heart tissues were decreased, whereas lipid peroxidation, advanced oxidized protein products, nitric oxide, homocysteine, and reactive oxygen species levels, total oxidant status and catalase, superoxide dismutase, glutathione peroxidase, glutathione reductase, glutathione-S-transferase, alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase and xanthine oxidase activities increased in the diabetic, cancer and DC groups. Treatment with metformin reversed these effects. In conclusion, the present study shows that metformin has a protective effect against heart tissue damage in STZ-induced diabetic rats with Dunning prostate cancer.

Unveiling prognostics biomarkers of tyrosine metabolism reprogramming in liver cancer by cross-platform gene expression analyses

Tyrosine is mainly degraded in the liver by a series of enzymatic reactions. Abnormal expression of the tyrosine catabolic enzyme tyrosine aminotransferase (TAT) has been reported in patients with hepatocellular carcinoma (HCC). Despite this, aberration in tyrosine metabolism has not been investigated in cancer development. In this work, we conduct comprehensive cross-platform study to obtain foundation for discoveries of potential therapeutics and preventative biomarkers of HCC. We explore data from The Cancer Genome Atlas (TCGA), Gene Expression Omnibus (GEO), Gene Expression Profiling Interactive Analysis (GEPIA), Oncomine and Kaplan Meier plotter (KM plotter) and performed integrated analyses to evaluate the clinical significance and prognostic values of the tyrosine catabolic genes in HCC. We find that five tyrosine catabolic enzymes are downregulated in HCC compared to normal liver at mRNA and protein level. Moreover, low expression of these enzymes correlates with poorer survival in patients with HCC. Notably, we identify pathways and upstream regulators that might involve in tyrosine catabolic reprogramming and further drive HCC development. In total, our results underscore tyrosine metabolism alteration in HCC and lay foundation for incorporating these pathway components in therapeutics and preventative strategies.

Relevance of SIRT1-NF-κB Axis as Therapeutic Target to Ameliorate Inflammation in Liver Disease

Inflammation is an adaptive response in pursuit of homeostasis reestablishment triggered by harmful conditions or stimuli, such as an infection or tissue damage. Liver diseases cause approximately 2 million deaths per year worldwide and hepatic inflammation is a common factor to all of them, being the main driver of hepatic tissue damage and causing progression from non-alcoholic fatty liver disease (NAFLD) to non-alcoholic steatohepatitis (NASH), cirrhosis and, ultimately, hepatocellular carcinoma (HCC). The metabolic sensor SIRT1, a class III histone deacetylase with strong expression in metabolic tissues such as the liver, and transcription factor NF-κB, a master regulator of inflammatory response, show an antagonistic relationship in controlling inflammation. For this reason, SIRT1 targeting is emerging as a potential strategy to improve different metabolic and/or inflammatory pathologies. In this review, we explore diverse upstream regulators and some natural/synthetic activators of SIRT1 as possible therapeutic treatment for liver diseases.
