RESUMO
INTRODUCTION: Mac-2-binding protein glycosylation isomer (M2BPGi) is a novel biomarker for liver fibrosis, but little is known about its role in cirrhosis-associated clinical outcomes. This study aimed to investigate the predictive role of M2BPGi in cirrhosis-associated complications. METHODS: One hundred and forty-nine cirrhotic patients were retrospectively enrolled. Patients were followed up for 1 year, and cirrhosis-associated clinical events were recorded. Receiver operating characteristic curve (ROC) analysis was used to establish the values of the predictive models for cirrhotic outcomes, and Cox proportional hazards regression models were used to identify predictors of clinical outcomes. RESULTS: Sixty (40.3%) patients experienced cirrhosis-associated clinical events and had higher M2BPGi levels compared to those without events (8.7 vs. 5.1 cutoff index, p < 0.001). The most common cirrhosis-associated complications were bacterial infections (24.2%). On ROC analysis, M2BPGi to albumin ratio (M2BPGi/albumin) had comparable discriminant abilities for all cirrhosis-associated events (area under the ROC curve [AUC] = 0.74) compared with M2BPGi, Child-Pugh, model for end-stage liver disease, albumin-bilirubin scores, and neutrophil-to-lymphocyte ratio and was superior to M2BPGi alone for all bacterial infectious events (AUC = 0.80). Cox regression analysis revealed that the M2BPGi/albumin, but not M2BPGi alone, independently predicted all cirrhosis-associated events (hazard ratio [HR] = 1.34, p = 0.038) and all bacterial infectious events (HR = 1.51, p = 0.011) within 1 year. However, M2BPGi/albumin did not predict other cirrhotic complications and transplant-free survival. DISCUSSION/CONCLUSION: M2BPGi/albumin might serve as a potential prognostic indicator for patients with cirrhosis, particularly for predicting bacterial infections.

BACKGROUND AND AIM: The association between long-term proton-pump inhibitors (PPIs) use and malignancies had long been discussed, but it still lacks consensus. Our study investigated the association between PPI use and hepatocellular carcinoma (HCC) recurrence following curative surgery. METHODS: We retrospectively enrolled 6037 patients with HCC who underwent hepatectomy. Patients were divided into four groups according to their PPI usage. (non-users: < 28 cumulative defined daily dose [cDDD]; short-term users: 28-89 cDDD; mid-term users: 90-179 cDDD, and long-term users: ≥ 180 cDDD, respectively). Recurrence-free survival (RFS) and overall survival (OS) were analyzed using Kaplan-Meier method and Cox proportional hazard models. RESULTS: Among the 6037 HCC patients, 2043 (33.84%) were PPI users. PPI users demonstrated better median RFS (3.10 years, interquartile range [IQR] 1.49-5.01) compared with non-users (2.73 years, IQR 1.20-4.74; with an adjusted hazard ratio [aHR] of 0.57, 95% confidence interval [CI] 0.44-0.74, P < 0.001). When considering the cumulative dosage of PPI, only long-term PPI users had significant lower risk of HCC recurrence than non-PPI group (adj-HR: 0.50; 95% CI: 0.35-0.70; P < 0.001). Moreover, the impact of long-term PPIs use on improving RFS was significant in most of the subgroup analysis, except in patients with advanced tumor stages, with non-cirrhosis, or with a history of chronic kidney disease. However, there were no significant differences in median OS between PPI users and non-users (4.23 years, IQR 2.73-5.86 vs 4.04 years, IQR 2.51-5.82, P = 0.369). CONCLUSION: Long-term PPI use (≥ 180 cDDD) may be associated with a better RFS in HCC patients after hepatectomy.
RESUMO
Atherosclerosis is characterized by the plaque formation that restricts intraarterial blood flow. The disturbed blood flow with the associated oscillatory stress (OS) at the arterial curvatures and branch points can trigger endothelial activation and is one of the risk factors of atherosclerosis. Many studies reported the mechanotransduction related to OS and atherogenesis; however, the transcriptional and posttranscriptional regulatory mechanisms of atherosclerosis remain unclear. Herein, we investigated the role of N6-methyladenosine (m6A) RNA methylation in mechanotransduction in endothelial cells (ECs) because of its important role in epitranscriptome regulation. We have identified m6A methyltransferase METTL3 as a responsive hub to hemodynamic forces and atherogenic stimuli in ECs. OS led to an up-regulation of METTL3 expression, accompanied by m6A RNA hypermethylation, increased NF-κB p65 Ser536 phosphorylation, and enhanced monocyte adhesion. Knockdown of METTL3 abrogated this OS-induced m6A RNA hypermethylation and other manifestations, while METTL3 overexpression led to changes resembling the OS effects. RNA-sequencing and m6A-enhanced cross-linking and immunoprecipitation (eCLIP) experiments revealed NLRP1 and KLF4 as two hemodynamics-related downstream targets of METTL3-mediated hypermethylation. The METTL3-mediated RNA hypermethylation up-regulated NLRP1 transcript and down-regulated KLF4 transcript through YTHDF1 and YTHDF2 m6A reader proteins, respectively. In the in vivo atherosclerosis model, partial ligation of the carotid artery led to plaque formation and up-regulation of METTL3 and NLRP1, with down-regulation of KLF4; knockdown of METTL3 via repetitive shRNA administration prevented the atherogenic process, NLRP3 up-regulation, and KLF4 down-regulation. Collectively, we have demonstrated that METTL3 serves a central role in the atherogenesis induced by OS and disturbed blood flow.

BACKGROUND: The characteristics and prognosis of cryptogenic hepatocellular carcinoma (HCC) remain unclear. The albumin-bilirubin (ALBI) grade and its updated version, the easy ALBI (EZ-ALBI) grade, are important prognostic predictors for HCC. We aimed to investigate the long-term survival of patients with cryptogenic HCC and the prognostic role of ALBI and EZ-ALBI grade in these patients. METHODS: A prospective cohort of 2,937 HCC patients with viral or cryptogenic etiology were retrospectively analyzed. The multivariate Cox model was used to determine prognostic predictors. RESULTS: Cryptogenic HCC patients were often older and diabetic, had lower serum É-fetoprotein (AFP) levels, larger tumor burden, poor performance status, advanced cancer stage, and received non-curative treatments compared with hepatitis B or C-related HCC. The Cox analysis showed that age > 65 years, serum AFP > 400 ng/mL, presence of vascular invasion or distant metastasis, presence of ascites, performance status 2-4, ALBI grade 2 and 3, EZ-ALBI grade 2 and 3, and non-curative treatment, were independent predictors of decreased survival in cryptogenic HCC (p < .001). Significant survival differences were found across ALBI grade and EZ-ALBI grade in cryptogenic HCC and subgroup patients receiving curative or non-curative treatments. The Cancer of Liver Italian Program was the best staging system for patients with cryptogenic HCC. CONCLUSIONS: Patients with cryptogenic HCC have a larger tumor burden and advanced cancer stage at disease presentation compared with those with viral HCC. The ALBI and EZ-ALBI score are robust models to evaluate liver functional reserve for these patients independent of treatment modality.

BACKGROUND: Alpha fetoprotein (AFP) is the most widely used tumor marker for hepatocellular carcinoma (HCC). Nevertheless, few studies have investigated the prognostic factors of HCC patients with normal serum AFP levels. METHODS: We retrospectively enrolled 2198 patients with HCC and normal serum AFP levels (<20 ng/mL) from 2007 to 2020. Overall survival (OS) rates were calculated by the Kaplan-Meier method, and analyses of the prognostic factors were performed using a Cox proportional hazard model. RESULTS: Among the enrolled patients, 1385 (63%) patients were in the low-normal AFP group (serum AFP levels ≤7 ng/mL), and 813 (37%) patients were in the high-normal AFP group (serum AFP levels between 7 and 20 ng/mL). The high-normal AFP group had poorer liver functional reserve, more multiple tumors, and smaller tumor size compared to those in the low-normal AFP group. After a median follow-up of 32.4 months, 942 patients died, and the 5-year OS rate was 54.4%. The 5-year OS rates were 57.4% and 49.8% in the low-normal AFP group and high-normal AFP group, respectively (p = 0.001). A multivariate analysis showed the independent prognostic factors of poor OS were no anti-viral therapy, advanced albumin-bilirubin grades, the presence of vascular invasion, tumor size ≥5 cm, and non-curative treatment modalities. Serum AFP levels were not associated with OS according to the multivariate analysis. CONCLUSION: Liver functional reserve, anti-viral therapy, tumor size, vascular invasion, and treatment modalities, determined the outcomes of HCC patients with normal serum AFP levels, but serum AFP levels did not.

The severity of liver functional reserve is an important prognostic predictor in hepatocellular carcinoma (HCC). The albumin-bilirubin (ALBI), easy (EZ)-ALBI, platelet-albumin-bilirubin (PALBI), platelet-albumin (PAL) score, and MELD 3.0 score are used to evaluate the severity of liver dysfunction. However, their prognostic role in HCC patients, specifically with renal insufficiency (RI), is unclear. We aimed to investigate the predictive accuracy of the five models in these patients. A total of 1120 newly diagnosed HCC patients with RI were enrolled. A multivariate Cox proportional analysis was used to identify independent predictors associated with survival. In the Cox model, older age, an α-fetoprotein ≥20 ng/mL, vascular invasion, a medium and high tumor burden score, poor performance status, a higher ALBI grade, an EZ-ALBI grade, a PALBI grade, a PAL grade, and MELD 3.0 score were all independently associated with decreased overall survival (all p < 0.001). Among the five liver reserve models, the ALBI grade is the best surrogate marker to represent liver functional reserve in terms of outcome prediction. The albumin-based liver reserve models (ALBI, EZ-ALBI, PALBI, and PAL) and MELD 3.0 are all feasible prognostic markers to indicate liver injury, specifically in HCC patients with RI. Among them, the ALBI grade is the most robust tool for survival prediction in these patients.

BACKGROUND: Albumin-bilirubin (ALBI) grade is used to evaluate the outcome of patients with hepatocellular carcinoma (HCC) which is often associated with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection. This study aimed to investigate the clinical characteristics, outcome, and prognostic role of ALBI grade in dual HBV/HCV-related HCC. METHODS: A total 3341 HCC patients with viral etiology were prospectively enrolled and retrospectively analyzed. Multivariate Cox proportional hazards model was used to identify independent prognostic predictors. RESULTS: Of all patients, 2083 (62%), 1068 (32%), and 190 (6%) patients had HBV, HCV, and dual HBV/HCV infection, respectively. The mean age of HBV, HCV, and dual virus group was 60, 68, and 64 years (p < 0.001), respectively. There was no significant survival difference between HBV, HCV, and dual HBV/HCV-related HCC group (p = 0.712). Multivariate Cox analysis in dual HBV/HCV-related HCC showed that multiple tumors [hazard ratio (HR): 1.537, p = 0.044], tumor size >3 cm (HR 2.014, p = 0.044), total tumor volume (TTV) >50 cm3 (HR 3.050, p < 0.001), vascular invasion (HR 3.258, p < 0.001), performance status 2-4 (HR 2.232, p < 0.001), ALBI grade 2-3 (HR 2.177, p < 0.001), and BCLC stage B-D (HR 2.479, p < 0.001) were independent predictors of poor survival. CONCLUSIONS: Dual viral infection does not accelerate the development of HCC in HBV carriers. Patient survival is similar between dual HBV/HCV-related HCC and single HBV- or HCV-related HCC group. The ALBI grade is a robust prognostic model in dual virus-related HCC to discriminate patient long-term survival.

BACKGROUND: Liver functional reserve is a major prognostic determinant in patients with hepatocellular carcinoma (HCC). The albumin-bilirubin (ALBI) score is an objective method to assess the severity of cirrhosis in this setting. However, calculation of the ALBI score is complex and difficult to access in clinical practice. Recently, the EZ (easy)-ALBI score was proposed as an alternative biomarker of liver injury. We aimed to evaluate the prognostic role of the EZ-ALBI score in HCC from early to advanced stages. METHODS: A total of 3794 newly diagnosed HCC patients were prospectively enrolled and retrospectively analyzed. Independent prognostic predictors were determined by using the multivariate Cox proportional hazards model. RESULTS: The EZ-ALBI score showed good correlation with the ALBI score (correlation coefficient, 0.965; p < 0.001). The correlation of the EZ-ALBI score was highly preserved in different Child-Turcotte-Pugh (CTP) classifications, treatment methods, and Barcelona Clinic Liver Cancer (BCLC) stages (correlation coefficients, 0.90-0.97). In the Cox multivariate analysis, age >65 years, male sex, serum α-fetoprotein >20 ng/ml, large or multiple tumors, total tumor volume >100 cm3 , vascular invasion or distant metastasis, ascites, poor performance status, EZ-ALBI grade 2 and 3, and noncurative treatments were independently associated with increased mortality (all p < 0.05). Moreover, EZ-ALBI grade can stratify long-term survival in patients with different CTP class, treatment strategy, and BCLC stage. CONCLUSIONS: The EZ-ALBI score is an easy and feasible method to evaluate liver functional reserve. As a new prognostic biomarker in HCC, the predictive power of the EZ-ALBI grade is independent across different cancer stages and treatments.
RESUMO
BACKGROUND AND AIM: Size and number are major determinants of tumor burden in hepatocellular carcinoma (HCC). Patients with HCC undergoing transarterial chemoembolization (TACE) have variable outcomes due to heterogeneity of tumor burden. Recently, tumor burden score (TBS) was proposed to evaluate the extent of tumor involvement. However, the prognostic accuracy of TBS has not been well evaluated in HCC. This study aimed to assess its prognostic role in HCC patients undergoing TACE. METHODS: A total of 935 treatment-naïve HCC patients receiving TACE were retrospectively analyzed. Multivariate Cox proportional hazards model was used to determine independent prognostic predictors. RESULTS: Tumor burden score tended to increase with increasing size and number of tumors in study patients. The Cox model showed that serum creatinine ≥ 1.2 mg/dL (hazard ratio [HR]: 1.296, 95% confidence interval [CI]: 1.077-1.559, P = 0.006), serum α-fetoprotein ≥ 400 ng/dL (HR: 2.245, 95% CI: 1.905-2.645, P < 0.001), vascular invasion (HR: 1.870, 95% CI: 1.520-2.301, P < 0.001), medium TBS (HR: 1.489, 95% CI: 1.206-1.839, P < 0.001) and high TBS (HR: 2.563, 95% CI: 1.823-3.602, P < 0.001), albumin-bilirubin (ALBI) grade 2-3 (HR: 1.521, 95% CI: 1.291-1.792, P < 0.001), and performance status 1 (HR: 1.362, 95% CI: 1.127-1.647, P < 0.001) and status 2 (HR: 1.553, 95% CI: 1.237-1.948, P < 0.001) were associated with increased mortality. Patients with high TBS had poor overall survival in Barcelona Clinic Liver Cancer stage B/C and different ALBI grades. CONCLUSIONS: Tumor burden score is a feasible new prognostic surrogate marker of tumor burden in HCC and can well discriminate survival in patients undergoing TACE across different baseline characteristics.

BACKGROUND/AIM: Patients with cirrhosis have poor outcomes once decompensation occurs; however, we lack adequate predictors of decompensation. To use a national claim database to compare the predictive accuracy of seven models for decompensation and hospitalization in patients with compensated cirrhosis. METHODS: We defined decompensation as ascites, hepatic encephalopathy, hepato-renal syndrome, and variceal bleeding. Patients without decompensation at the time of cirrhosis diagnosis were enrolled from 2001 to 2015. Patients with hepatitis B and/or C were grouped as viral cirrhosis. We compared the predictive accuracy of models with the AUC (area under the curve) and c-statistic. The cumulative incidence of decompensation and incidence risk ratios of hospitalization were calculated with the Fine-Gray competing risk and negative binomial models, respectively. RESULTS: A total of 3722 unique patients were enrolled with a mean follow-up time of 524 days. The mean age was 59 (standard deviation 12), and the majority were male (55%) and white (65%). Fifty-three percent of patients had non-viral cirrhosis. Sixteen and 20 percent of patients with non-viral and viral cirrhosis, respectively, developed decompensation (P = 0.589). The FIB-4 model had the highest 3-year AUC (0.73) and overall c-statistic (0.692) in patients with non-viral cirrhosis. The ALBI-FIB-4 model had the best 1-year (AUC = 0.741), 3-year (AUC = 0.754), and overall predictive accuracy (c-statistic = 0.681) in patients with viral cirrhosis. The MELD score had the best predictive power for hospitalization in both non-viral and viral patients. CONCLUSIONS: FIB-4-based models provide more accurate prediction for decompensation, and the MELD model has the best predictive ability of hospitalization.

BACKGROUND/AIM: The prognosis of patients with hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) is highly heterogeneous because of variable characteristics of tumor burden and liver dysfunction. We aimed to propose and validate an albumin-bilirubin (ALBI) grade-based prognostic nomogram for HCC patients undergoing TACE. METHODS: A total of 1051 patients with HCC undergoing TACE were randomly assigned to derivation (n = 525) and validation (n = 526) set in this retrospective study based on prospective data. The multivariate Cox proportional hazards model in derivation set was used to generate the nomogram. The predictive accuracy of the nomogram was evaluated by discrimination and calibration tests. RESULTS: In multivariate analysis, presence of ascites, ALBI grade 2-3, serum É-fetoprotein level ≥ 400 ng/mL, total tumor volume ≥ 396 cm3, presence of vascular invasion, and poor performance status were independently associated with decreased survival of patients in the derivation set. Each patient had an individualized score from 0 to 41 by adding up the points from these six prognostic predictors. The nomogram generated from the derivation set had a concordance index of 0.72 (95% confidence interval [CI] 0.63-0.82). Discrimination test in the validation set provided a good concordance index 0.72 (95% CI 0.62-0.81), and the calibration plots consistently matched the ideal 45-degree reference line for 3- and 5-year survival prediction. CONCLUSIONS: The ALBI grade-based prognostic model can well discriminate the survival in HCC patients undergoing TACE. The proposed easy-to-use nomogram may accurately predict the survival at 3 and 5 years for individual HCC patient in the precision medicine era.

Pluripotency and cell fates can be modulated through the regulation of super-enhancers; however, the underlying mechanisms are unclear. Here, we showed a novel mechanism in which Ash2l directly binds to super-enhancers of several stemness genes to regulate pluripotency and self-renewal in pluripotent stem cells. Ash2l recruits Oct4/Sox2/Nanog (OSN) to form Ash2l/OSN complex at the super-enhancers of Jarid2, Nanog, Sox2 and Oct4, and further drives enhancer activation, upregulation of stemness genes, and maintains the pluripotent circuitry. Ash2l knockdown abrogates the OSN recruitment to all super-enhancers and further hinders the enhancer activation. In addition, CRISPRi/dCas9-mediated blocking of Ash2l-binding motifs at these super-enhancers also prevents OSN recruitment and enhancer activation, validating that Ash2l directly binds to super-enhancers and initiates the pluripotency network. Transfection of Ash2l with W118A mutation to disrupt Ash2l-Oct4 interaction fails to rescue Ash2l-driven enhancer activation and pluripotent gene upregulation in Ash2l-depleted pluripotent stem cells. Together, our data demonstrated Ash2l formed an enhancer-bound Ash2l/OSN complex that can drive enhancer activation, govern pluripotency network and stemness circuitry.

BACKGROUND/PURPOSE: Hepatocellular carcinoma (HCC) is a highly recurrent tumor. Antiviral therapy with nucleos(t)ide analogues (NUCs) may reduce the risk of recurrence in hepatitis B virus (HBV)-related HCC. The risk factors associated with recurrence in HCC patients after surgical resection and with NUCs treatment should be delineated. METHODS: Consecutive 339 HBV-related HCC patients receiving surgical resection of HCC with NUCs therapy (including 256 entecavir, 36 tenofovir, and 18 lamivudine) after the surgery were retrospectively reviewed. Factors related to the recurrence-free survival (RFS) and overall survival (OS) were evaluated. RESULTS: After a median of 48.5 months of follow-up, 183 (54%) patients developed HCC recurrence, with the 5-year RFS of 42.8% and OS of 79%. Male gender (HR = 1.736, p = 0.037), baseline HBsAg level >200 IU/ml (HR = 1.748, p = 0.008), platelet count â¦100 (109/L) (HR = 1.592, p = 0.023), presence of microscopic vascular invasion (MVI) (HR = 1.499, p = 0.026), safety cut margin of â¦0.5 cm (HR = 1.507, p = 0.013), and Ishak fibrosis score 5-6 (HR = 1.579, p = 0.009) were independent factors associated with RFS in multivariate analysis. While tumor burden, platelet count, MVI, and safety cut margin were factors associated with early recurrence; baseline HBsAg level, and platelet count were independent factors associated with late recurrence. Ishak fibrosis score 5-6, poor differentiation, MVI, diabetes mellitus were factors associated with OS in multivariate analysis. CONCLUSION: For HBV-HCC patients on NUCs treatment, tumor factors are associated with early recurrence, while HBsAg level and thrombocytopenia determines late recurrence. For patient with a high baseline HBsAg level, warning of higher risk of recurrence is required even under NUCs treatment.

Researchers have hypothesized that the long-term use of proton pump inhibitors (PPIs) can increase the risk of developing cancer. However, the association between PPI use and hepatocellular carcinoma (HCC) risk is unclear. Using data from the Taiwan National Health Insurance Research Database for the period between 2003 and 2013, we identified 35,356 patients with chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infections. One-to-one propensity score matching by gender, age, cohort entry year, comorbidity, and medication resulted in the inclusion of 7,492 pairs of patients (PPI users and non-PPI users) for analyses. We performed multivariate and stratified analysis using the Kaplan-Meier method and Cox proportional hazards models in order to estimate the association between PPI use and the risk of developing HCC. In the HBV cohort, 237 patients developed HCC during a median follow-up of 53 months. However, PPI use was not associated with an increased risk of developing HCC (adjusted hazard ratio [aHR], 1.25; 95% confidence interval [CI], 0.90-1.73; P = 0.18). In the HCV cohort, 211 patients developed HCC; but again, PPI use was not associated with an increase in the risk of developing HCC (aHR, 1.19; 95% CI, 0.88-1.61; P = 0.25). We observed no relationship between a dose-dependent effect of PPI use and HCC risk. Subgroup analysis also confirmed that PPI use was not correlated to an increased HCC risk. Conclusion: Based on a retrospective population-based cohort study throughout Taiwan, where the prescription of PPI is tightly regulated, PPI use is not associated with the risk of developing HCC among patients with chronic HBV or HCV infections.

BACKGROUND & AIMS: Thrombocytosis is associated with more aggressive tumour biology in many malignancies. There are limited data in patients with hepatocellular carcinoma (HCC), which often occurs in patients with cirrhosis and portal hypertension. We aimed to explore the prognostic value of thrombocytosis in two cohorts of patients with HCC. METHODS: We included 3561 patients from Taiwan and 1145 patients from the USA. Thrombocytopenia was defined as platelet count < 150×109 /L and thrombocytosis as ≥ 300 × 109 /L at HCC diagnosis. We used multivariable Cox proportional hazard models to identify independent predictors of survival. RESULTS: Thrombocytosis was present in 9.0% and 6.9% of Taiwan and USA patients respectively. Compared to patients with normal platelet counts and those with thrombocytopenia, patients with thrombocytosis had larger tumours, increased vascular invasion and a higher proportion had extrahepatic metastases in both cohorts. In multivariable analysis, thrombocytosis (aHR 1.40, 95% CI 1.23-1.60) and thrombocytopenia (aHR 1.13, 95% CI 1.04-1.23) were both associated with worse survival after adjusting for age, gender, liver disease aetiology, Child-Pugh score, maximal tumour size, tumour nodularity, vascular invasion, lymph node or distant metastasis, performance status and alpha-fetoprotein level. Patients with thrombocytosis had a median survival of 6 and 4 months in the Taiwan and USA cohorts, compared to 32 and 14 months for those with normal platelet counts and 38 and 16 months for thrombocytopenic patients. CONCLUSION: Thrombocytosis is independently associated with increased tumour burden and worse overall survival among HCC patients.

BACKGROUND & AIMS: The prognostic accuracy of individual hepatocellular carcinoma (HCC) patient in each Barcelona Clinic Liver Cancer (BCLC) stage is unclear. We aimed to develop and validate an albumin-bilirubin (ALBI) grade-based nomogram of BCLC to estimate survival for individual HCC patient. METHODS: Between 2002 and 2016, 3690 patients with newly diagnosed HCC were prospectively enrolled and retrospectively analysed. Patients were randomly split into derivation and validation cohort by 1:1 ratio. Multivariate Cox proportional hazards model was used to generate the nomogram from tumour burden, ALBI grade and performance status (PS). The concordance index and calibration plot were determined to evaluate the performance of this nomogram. RESULTS: Beta coefficients from the Cox model were used to assign nomogram points to different degrees of tumour burden, ALBI grade and PS. The scores of the nomogram ranged from 0 to 24, and were used to predict 3- and 5-year patient survival. The concordance index of this nomogram was 0.77 (95% confidence interval [CI]: 0.71-0.81) in the derivation cohort and 0.76 (95% CI: 0.71-0.81) in the validation cohort. The calibration plots to predict both 3- and 5-year survival rate well matched with the 45-degree ideal line for both cohorts, except for ALBI-based BCLC stage 0 in the validation cohort. CONCLUSIONS: The proposed ALBI-based nomogram of BCLC system is a simple and feasible strategy in the precision medicine era. Our data indicate it is a straightforward and user-friendly prognostic tool to estimate the survival of individual HCC patient except for very early stage patients.

BACKGROUND: Diabetes mellitus (DM) is common in patients with hepatocellular carcinoma (HCC) and may impact survival. Very few studies focused on the influence of DM in different clinical scenarios. We evaluated the prognostic impact of DM on HCC patients stratified by liver dysfunction, Milan criteria, and performance status defined in the Barcelona Clínic Liver Cancer staging parameters. METHODS: A prospective dataset of 3573 HCC patients between 2002 and 2016 was retrospectively analyzed. The multivariate Cox proportional hazards model was used to identify independent prognostic predictors. The Kaplan-Meier method with a log-rank test was applied to compare the survival distributions between different patient groups. RESULTS: Among all, DM was not an independent prognostic predictor in the Cox multivariate analysis (p = 0.1044). In the subgroup analysis, DM was not a significant prognostic predictor in Child-Turcotte-Pugh class A or class B/C patients. However, DM was associated with a decreased survival in patients within the Milan criteria (hazard ratio [HR] 1.36, 95% confidence interval [CI] 1.155-1.601, p = 0.0002) and in those with the performance status 0 (HR 1.213, 95% CI 1.055-1.394, p = 0.0067) in the multivariate Cox analysis, but not in those beyond the Milan criteria and poor performance status. CONCLUSIONS: DM is highly prevalent in HCC patients and has a distinct survival impact. DM is an independent survival predictor among patients within the Milan criteria and good performance status. These high-risk patients should be closely monitored, and aggressive anticancer treatment should be considered.

BACKGROUND: The survival of patients with advanced hepatocellular carcinoma (HCC) is highly variable due to heterogeneous tumoral characteristics. We proposed and validated an albumin-bilirubin (ALBI)-based model for HCC beyond Milan criteria, the ALBI-HOME, for these patients. METHODS: A total of 2186 patients were enrolled and randomly assigned to the derivation cohort (n = 1093) and validation cohort (n = 1093). Multivariate Cox proportional hazards model was used to determine significant prognostic factors in the derivation cohort. The performance of ALBI-HOME was evaluated in the validation cohort. RESULTS: In the Cox model, six factors were identified as independent predictors of poor survival: ALBI grade 2 [hazard ratio (HR) 1.848, 95% confidence incidence (CI) 1.556-2.195, p < 0.001], ALBI grade 3 (HR 3.266, 95% CI 2.531-4.215, p < 0.001), serum AFP ≥ 100 ng/ml (HR 1.482, 95% CI 1.279-1.717, p < 0.001), total tumor volume ≥ 250 cm3 (HR 1.503, 95% CI 1.294-1.746, p < 0.001), ascites (HR 1.400, 95% CI 1.187-1.561, p < 0.001), performance status 0-1 (HR 1.756, 95% CI 1.485-2.076 p < 0.001), and vascular invasion or metastasis (HR 2.110, 95% CI 1.809-2.0, p < 0.001). The ALBI-HOME is based on these six parameters, and the score ranges from 0 to 7. This model was associated with the best prognostic ability among different HCC staging systems to predict survival in patients beyond Milan criteria; its ability remained consistently stable in different treatment subgroups and viral etiologies. CONCLUSIONS: The proposed ALBI-HOME is a simple and feasible predictive model for HCC beyond Milan criteria. It demonstrates superior prognostic performance among the currently used staging systems and may help identify at-risk patients to undergo more aggressive treatments.

BACKGROUND/PURPOSE: The risk of recurrence after resection of hepatocellular carcinoma (HCC) is high. Apart from nucleos(t)ide analogues therapy, population-based studies suggest statin, nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin have chemopreventive effect on recurrence. The role of those drugs on HCC recurrence should be delineated. METHODS: Consecutive 430 hepatitis B surface antigen (HBsAg)-positive patients undergoing curative resection of HCC were enrolled. The detailed medical records including the use of statin, NSAID and aspirin were reviewed. All the patients had regular image study surveillance after the surgery. Predictors associated with recurrence were analyzed by Cox's proportional hazards models. RESULTS: There were 58.8% patients in Barcelona Clinic Liver Cancer (BCLC) stage A, and 37.6% had severe liver fibrosis or cirrhosis. Of them, 47 (10.9%) patients had received potential chemoprophylactic agents either at the time of HCC diagnosis or before their HCC recurrence. During a median 50.3 months of follow-up, 54.7% patients experienced recurrence. The median time to recurrence was 15.4 months. In the univariate analysis, aspirin and statins use were significantly associated a low risk of recurrence (hazard ratio [HR]: 0.18; p = 0.016, and HR: 0.50; p = 0.031, respectively). After adjusting competing factors, large tumor size, severe liver fibrosis, and high alpha-fetoprotein (AFP) level were significantly associated with recurrence. Importantly, aspirin use was found to significantly decrease the risk for HCC recurrence with the adjusted HRs of 0.22-0.24 based on the models. CONCLUSION: Aspirin use may have chemo-preventive effect on recurrence of hepatitis B virus-related HCC after curative resection.

BACKGROUND/PURPOSE: Whether esophagogastric varices (EGV) can determine the outcome of patients with hepatocellular carcinoma (HCC) after transarterial chemoembolization (TACE) remains unknown. This study aimed to assess the impact of EGV on the prognosis of HCC patients after TACE. METHODS: From 2007 to 2012, we retrospectively enrolled 251 treatment-naïve HCC patients who underwent TACE and received esophagogastroduodenoscopy when HCC was diagnosed. The prognostic factors were analyzed using a Cox proportional hazards model and propensity score-matching analysis. RESULTS: There were 120 (47.8%) patients with EGV. Compared to those without EGV, patients with EGV had worse liver functional reserve. After a median follow-up of 14.7 months (25th-75th percentiles, 6.4-35.6 months), 152 patients died. The cumulative 5-year overall survival (OS) rates were 11.2% and 38.8% in patients with and without EGV, respectively (p < 0.001). Multivariate analysis showed that presence of EGV, presence of ascites, tumor size >5 cm, serum alpha-fetoprotein >20 ng/mL, progressive disease by modified Response Evaluation Criteria in Solid Tumors, Assessment for Retreatment with TACE score ≥2.5, and higher albumin-bilirubin grades were the independent predictors of poor OS. Subgroup analysis also demonstrated that EGV was associated with poor OS in most of the subgroups. After propensity score matching, the EGV group still had a lower OS rate than their counterparts (p = 0.004). CONCLUSION: HCC patients with EGV had worse liver functional reserve compared to those without EGV. Moreover, EGV was an independent risk factor to predict poor prognosis in patients with HCC after TACE.
