Abstract
Bile acids (BAs) play different roles in cancer development. Some are carcinogenic and BA signaling is also involved in various metabolic, inflammatory and immune-related processes. The liver is the primary site of BA synthesis. Liver dysfunction and microbiome compositional changes, such as during hepatocellular carcinoma (HCC) development, may modulate BA metabolism increasing concentration of carcinogenic BAs. Observations from prospective cohorts are sparse. We conducted a study (233 HCC case-control pairs) nested within a large observational prospective cohort with blood samples taken at recruitment when healthy with follow-up over time for later cancer development. A targeted metabolomics method was used to quantify 17 BAs (primary/secondary/tertiary; conjugated/unconjugated) in prediagnostic plasma. Odd ratios (OR) for HCC risk associations were calculated by multivariable conditional logistic regression models. Positive HCC risk associations were observed for the molar sum of all BAs (ORdoubling = 2.30, 95% confidence intervals [CI]: 1.76-3.00), and choline- and taurine-conjugated BAs. Relative concentrations of BAs showed positive HCC risk associations for glycoholic acid and most taurine-conjugated BAs. We observe an association between increased HCC risk and higher levels of major circulating BAs, from several years prior to tumor diagnosis and after multivariable adjustment for confounders and liver functionality. Increase in BA concentration is accompanied by a shift in BA profile toward higher proportions of taurine-conjugated BAs, indicating early alterations of BA metabolism with HCC development. Future studies are needed to assess BA profiles for improved stratification of patients at high HCC risk and to determine whether supplementation with certain BAs may ameliorate liver dysfunction.

Abstract
BACKGROUND Hepatocellular carcinoma is a frequent consequence of alcohol-related liver disease, with variable incidence among heavy drinkers. We did a genome-wide association study (GWAS) to identify common genetic variants for alcohol-related hepatocellular carcinoma. METHODS We conducted a two-stage case-control GWAS in a discovery cohort of 2107 unrelated European patients with alcohol-related liver disease aged 20-92 years recruited between Oct 22, 1993, and March 12, 2017. Cases were patients with alcohol-related hepatocellular carcinoma diagnosed by imaging or histology. Controls were patients with alcohol-related liver disease without hepatocellular carcinoma. We used an additive logistic regression model adjusted for the first ten principal components to assess genetic variants associated with alcohol-related hepatocellular carcinoma. We did another analysis with adjustment for age, sex, and liver fibrosis. New candidate associations (p<1 × 10-6) and variants previously associated with alcohol-related hepatocellular carcinoma were evaluated in a validation cohort of 1933 patients with alcohol-related liver disease aged 29-92 years recruited between July 21, 1995, and May 2, 2019. We did a meta-analysis of the two case-control cohorts. FINDINGS The discovery cohort included 775 cases and 1332 controls. Of 7 962 325 variants assessed, we identified WNT3A-WNT9A (rs708113; p=1·11 × 10-8) and found support for previously reported regions associated with alcohol-related hepatocellular carcinoma risk at TM6SF2 (rs58542926; p=6·02 × 10-10), PNPLA3 (rs738409; p=9·29 × 10-7), and HSD17B13 (rs72613567; p=2·49 × 10-4). The validation cohort included 874 cases and 1059 controls and three variants were replicated: WNT3A-WNT9A (rs708113; p=1·17 × 10-3), TM6SF2 (rs58542926; p=4·06 × 10-5), and PNPLA3 (rs738409; p=1·17 × 10-4). All three variants reached GWAS significance in the meta-analysis: WNT3A-WNT9A (odds ratio 0·73, 95% CI 0·66-0·81; p=3·93 × 10-10), TM6SF2 (1·77, 1·52-2·07; p=3·84×10-13), PNPLA3 (1·34, 1·22-1·47; p=7·30 × 10-10). Adjustment for clinical covariates yielded similar results. We observed an additive effect of at-risk alleles on alcohol-related hepatocellular carcinoma. WNT3A-WNT9A rs708113 was not associated with liver fibrosis. INTERPRETATION WNT3A-WNT9A is a susceptibility locus for alcohol-related hepatocellular carcinoma, suggesting an early role of the Wnt-β-catenin pathway in alcohol-related hepatocellular carcinoma carcinogenesis.

Abstract
Previous in vitro and in vivo experiments had demonstrated dose-dependent anti-cancer effects of clinical plasma colchicine concentrations on hepatocellular carcinoma (HCC) cells. This phase IIa trial was to evaluate the potential efficiency and safety of our novel colchicine dosage schedule for the palliative treatment of advanced HCC. The dosage schedule started from oral intake of 1 mg colchicine three times per day for 4 days and discontinuation in the following 3 days (one cycle). The treatment cycle was repeated and the dosage was adjusted ranging from 3 to 1.5 mg/day according to the condition of the participant. The control group was originated from chart review of 86 HCC patients treated by sorafenib for more than 2 months. Fifteen participants signed the inform consent. Two participants were excluded due to screening failure in one and less than four treatment cycles in another. For severe adverse events, the colchicine group demonstrated higher incidence of biliary tract obstruction (p = 0.0184) than the sorafenib group. Comparison grade 1 or 2 adverse events between two groups, the colchicine group had higher incidence of diarrhea (p = 0) and the sorafenib group had higher incidence of palmar-plantar erythrodysesthesia syndrome (p = 0.0045). There was no significant difference in mortality, median survival, and overall survival between two groups (all p > 0.2). In conclusion, our novel colchicine dosage schedule is clinically feasible and has the potential to be applied in the palliative treatment of advanced HCC especially based on the cost-effectiveness consideration.

Abstract
BACKGROUND/AIM: The aim of this study was to reveal the novel roles of calmodulin 2 (CALM2) in hepatocellular carcinoma (HCC) progression. MATERIALS AND METHODS The effects of knockdown of CALM2 expression by siRNA were investigated using various experimental approaches in both cellular and molecular levels. RESULTS Silencing of CALM2 inhibited HCC cell proliferation and colony formation through induction of apoptosis. At the molecular level, CALM2-specific knockdown led to the common dysregulation of 154 genes in HCC cells. Notably, E2F transcription factor 5 (E2F5), which is functionally associated with migration, invasion and proliferation, was generally down-regulated. These functional associations were confirmed in HCC clinical samples. Reflecting the molecular changes, CALM2 knockdown reduced the migration and invasion abilities of HCC cells and abrogated the potency of tumor formation in vivo. CONCLUSION Targeting CALM2 may be a molecular strategy for both primary HCC treatment and prevention of metastasis or recurrence.

Abstract
PURPOSE Donafenib, a novel multikinase inhibitor and a deuterated sorafenib derivative, has shown efficacy in phase Ia and Ib hepatocellular carcinoma (HCC) studies. This study compared the efficacy and safety of donafenib versus sorafenib as first-line therapy for advanced HCC. PATIENTS AND METHODS This open-label, randomized, parallel-controlled, multicenter phase II-III trial enrolled patients with unresectable or metastatic HCC, a Child-Pugh score ≤ 7, and no prior systemic therapy from 37 sites across China. Patients were randomly assigned (1:1) to receive oral donafenib (0.2 g) or sorafenib (0.4 g) twice daily until intolerable toxicity or disease progression. The primary end point was overall survival (OS), tested for noninferiority and superiority. Efficacy was primarily assessed in the full analysis set (FAS), and safety was assessed in all treated patients. RESULTS Between March 21, 2016, and April 16, 2018, 668 patients (intention-to-treat) were randomly assigned to donafenib and sorafenib treatment arms; the FAS included 328 and 331 patients, respectively. Median OS was significantly longer with donafenib than sorafenib treatment (FAS; 12.1 v 10.3 months; hazard ratio, 0.831; 95% CI, 0.699 to 0.988; P = .0245); donafenib also exhibited superior OS outcomes versus sorafenib in the intention-to-treat population. The median progression-free survival was 3.7 v 3.6 months (P = .0570). The objective response rate was 4.6% v 2.7% (P = .2448), and the disease control rate was 30.8% v 28.7% (FAS; P = .5532). Drug-related grade ≥ 3 adverse events occurred in significantly fewer patients receiving donafenib than sorafenib (125 [38%] v 165 [50%]; P = .0018). CONCLUSION Donafenib showed superiority over sorafenib in improving OS and has favorable safety and tolerability in Chinese patients with advanced HCC, showing promise as a potential first-line monotherapy for these patients.

Gut microbiota alterations are distinct for primary colorectal cancer and hepatocellular carcinoma.
Jia, W, Rajani, C, Xu, H, Zheng, X
Protein & cell. 2021;(5):374-393
Abstract
Colorectal cancer (CRC) and hepatocellular carcinoma (HCC) are the second and third most common causes of death by cancer, respectively. The etiologies of the two cancers are either infectious insult or due to chronic use of alcohol, smoking, diet, obesity and diabetes. Pathological changes in the composition of the gut microbiota that lead to intestinal inflammation are a common factor for both HCC and CRC. However, the gut microbiota of the cancer patient evolves with disease pathogenesis in unique ways that are affected by etiologies and environmental factors. In this review, we examine the changes that occur in the composition of the gut microbiota across the stages of the HCC and CRC. Based on the idea that the gut microbiota are an additional "lifeline" and contribute to the tumor microenvironment, we can observe from previously published literature how the microbiota can cause a shift in the balance from normal → inflammation → diminished inflammation from early to later disease stages. This pattern leads to the hypothesis that tumor survival depends on a less pro-inflammatory tumor microenvironment. The differences observed in the gut microbiota composition between different disease etiologies as well as between HCC and CRC suggest that the tumor microenvironment is unique for each case.

Abstract
The purpose of this study was to identify and compare the diagnostic performance of gadolinium-ethoxybenzyl-diethyltriethylenetriacetic acid (Gd-EOB-DTPA) enhanced magnetic resonance imaging (MRI) and contrast-enhanced ultrasound (CEUS) in hepatocellular carcinoma (HCC).Two researchers searched PubMed, EMBASE, and Cochrane Library databases from the inception of each database to 10 February 2020, to find comparative studies of Gd-EOB-DTPA-MRI and CEUS in detection of HCC.The study included eight studies (374 patients). MRI is superior to CEUS in diagnostic sensitivity of HCC, P = .03. The diagnostic sensitivity of MRI in lesions with a diameter of less than 30 mm was significantly higher than that of CEUS, P = .04. MRI and CEUS had no significant difference in diagnostic specificity of HCC, P = .95. Summary Receiver Operating Characteristics (SROC) of MRI showed a larger than that of CEUS, but with P > .05.Gd-EOB-DTPA-MRI showed higher sensitivity than CEUS for hepatocellular carcinoma lesions, especially for lesions of less than 30 mm across.

Abstract
Background Sorafenib (Sor) remains a first-line option for hepatocellular carcinoma (HCC) or refractory renal cell carcinomas (RCC). PLC/PRF/5 HCC model showed upregulation of hypoxia with enhanced efficacy when Sor is combined with hypoxia-activated prodrug evofosfamide (Evo). Methods This phase IB 3 + 3 design investigated 3 Evo dose levels (240, 340, 480 mg/m2 on days 8, 15, 22), combined with Sor 200 mg orally twice daily (po bid) on days 1-28 of a 28-day cycle. Primary objectives included determining maximum tolerated dose (MTD) and recommended phase II dose (RP2D) of Sor + Evo. Results Eighteen patients were enrolled (median age 62.5 years; 17 male /1 female; 12 HCC/6 RCC) across three dose levels (DL0: Sor 200 mg bid/Evo 240 mg/m2 [n = 6], DL1:Sor 200 mg bid/Evo 480 mg/m2 [n = 5], DL1a: Sor 200 mg bid/Evo 340 mg/m2 [n = 7]). Two dose-limiting toxicities (DLTs) were reported with Evo 480 mg/m2 (grade 3 mucositis, grade 4 hepatic failure). Grade 3 rash DLT was observed in one patient at Evo 240 mg/m2. No DLTs were observed at Evo 340 mg/m2. MTD and RP2D were established as Sor 200 mg/Evo 340 mg/m2 and Sor 200/Evo 240 mg/m2, respectively. The most common treatment-related adverse events included fatigue, hand-foot syndrome, hypertension, and nausea/vomiting. Two partial responses were observed, one each at DL0 and DL1a.; disease control rate was 55%. Conclusions RP2D was established as sorafenib 200 mg bid + Evo 240 mg/m2. While preliminary anti-tumor activity was observed, future development must account for advances in immunotherapy in HCC/RCC.

Abstract
BACKGROUND AND AIMS Thiazolidinediones (TZDs) and glucagon-like peptide-1 (GLP-1) receptor agonists are potential pharmacological treatment options for patients at risk of NAFLD. Therefore, we examined the association between the risk of NAFLD and the use of TZDs and GLP-1 receptor agonists compared with the use of sulfonylureas (SUs) and insulins. Additionally, we calculated the incidence of HCC in users of TZDs and GLP-1 receptor agonists. APPROACH AND RESULTS We conducted a population-based cohort study using primary care data from the Clinical Practice Research Datalink database (2007-2018). All patients aged ≥18 with a prescription of an oral glucose-lowering agent or GLP-1 receptor agonist were included. The first prescription defined the start of follow-up. The primary outcome was a new diagnosis of NAFLD. Cox proportional hazards regression was used to estimate HRs and 95% CIs of the primary outcome. Incidence rates of HCC were determined per 1,000 person-years for all exposures. The study identified 207,367 adults with a prescription for a glucose-lowering agent. The risk of NAFLD was lower in patients prescribed a TZD than in those prescribed an SU (adjusted HR [aHR], 0.32; 95% CI, 0.20-0.51). No difference in risk of NAFLD was observed comparing GLP-1 receptor agonist use with insulin use (aHR, 1.22; 95% CI, 0.91-1.63). CONCLUSIONS Results of our study endorse the use of TZDs for selected patients at risk of NAFLD but do not support previous findings regarding the beneficial effect of GLP-1 receptor agonists. The low number of events in several subgroups may affect the generalizability of the current findings.

Abstract
BACKGROUND Tumour growth patterns have important implications for surveillance intervals, prognostication and treatment decisions but have not been well described for hepatocellular carcinoma (HCC). The aim of our study was to characterise HCC doubling time and identify correlates for indolent and rapid growth patterns. METHODS We performed a systematic literature review of Medline and EMBASE databases from inception to December 2019 and national meeting abstracts from 2010 to 2018. We identified studies reporting HCC tumour growth or tumour volume doubling time (TVDT), without intervening treatment, and abstracted data to calculate TVDT and correlates of growth patterns (rapid defined as TVDT <3 months and indolent as TVDT >9 months). Pooled TVDT was calculated using a random-effects model. RESULTS We identified 20 studies, including 1374 HCC lesions in 1334 patients. The pooled TVDT was 4.6 months (95% CI 3.9 to 5.3 months I2=94%), with 35% classified as rapid, 27.4% intermediate and 37.6% indolent growth. In subgroup analysis, studies from Asia reported shorter TVDT than studies elsewhere (4.1 vs 5.8 months). The most consistent correlates of rapid tumour growth included hepatitis B aetiology, smaller tumour size (continuous), alpha fetoprotein doubling time and poor tumour differentiation. Studies were limited by small sample sizes, measurement bias and selection bias. CONCLUSION TVDT of HCC is approximately 4-5 months; however, there is heterogeneity in tumour growth patterns, including more aggressive patterns in Asian hepatitis B-predominant populations. Identifying correlates of tumour growth patterns is important to better individualise HCC prognostication and treatment decisions.
