Chronic Viral Hepatitis B and C Outweigh MASLD in the Associated Risk of Cirrhosis and HCC.

BACKGROUND & AIMS: The impact of metabolic dysfunction-associated steatotic liver disease (MASLD) on the development of cirrhosis and hepatocellular carcinoma (HCC) by chronic hepatitis B (CHB) or C infection and antiviral treatment statuses is not well-known. METHODS: A total of 336,866 adults aged ≥30 years were prospectively enrolled in a health screening program between 1997-2013. MASLD was identified by abdominal ultrasonography and cardiometabolic profiles. Data linkage was performed using 3 nationwide databases-National Health Insurance, Cancer Registry, and Death Certification System-to obtain information on antiviral treatment, vital status, and newly diagnosed cirrhosis and HCC. Follow-up was conducted until December 31, 2019. RESULTS: In the total population, 122,669 (36.4%) had MASLD. Over a mean follow-up of 15 years, 5562 new cases of cirrhosis and 2273 new cases of HCC were diagnosed. Although MASLD significantly increased the cumulative risks of cirrhosis or HCC (P < .0001), the associated risk was more pronounced when comparing CHB or C infection with the presence of MASLD. Stratifying the participants based on their MASLD and CHB or C statuses, hazard ratios (HRadj) with 95% confidence intervals for HCC were 8.81 (7.83-9.92) for non-steatotic liver disease (SLD) with CHB or C, 1.52 (1.32-1.74) for MASLD without CHB or C, and 8.86 (7.76-10.12) for MASLD with CHB or C, compared with non-SLD without CHB or C (all P < .0001). Among CHB or C patients who received antivirals during follow-up, MASLD was associated with increased risks of cirrhosis and HCC, with HRadj of 1.23 (1.01-1.49) and 1.32 (1.05-1.65), respectively. CONCLUSIONS: These findings underscore the need to prioritize treatment of chronic viral hepatitis before addressing MASLD.

Long-term Risks of Cirrhosis and Hepatocellular Carcinoma Across Steatotic Liver Disease Subtypes.

INTRODUCTION: The prospective study aimed to investigate the long-term associated risks of cirrhosis and hepatocellular carcinoma (HCC) across various subtypes of steatotic liver disease (SLD). METHODS: We enrolled 332,175 adults who participated in a health screening program between 1997 and 2013. Participants were categorized into various subtypes, including metabolic dysfunction-associated SLD (MASLD), MASLD with excessive alcohol consumption (MetALD), and alcohol-related liver disease (ALD), based on ultrasonography findings, alcohol consumption patterns, and cardiometabolic risk factors. We used computerized data linkage with nationwide registries from 1997 to 2019 to ascertain the incidence of cirrhosis and HCC. RESULTS: After a median follow-up of 16 years, 4,458 cases of cirrhosis and 1,392 cases of HCC occurred in the entire cohort, resulting in an incidence rate of 86.1 and 26.8 per 100,000 person-years, respectively. The ALD group exhibited the highest incidence rate for cirrhosis and HCC, followed by MetALD, MASLD, and non-SLD groups. The multivariate adjusted hazard ratios for HCC were 1.92 (95% confidence interval [CI] 1.51-2.44), 2.91 (95% CI 2.11-4.03), and 2.59 (95% CI 1.93-3.48) for MASLD, MetALD, and ALD, respectively, when compared with non-SLD without cardiometabolic risk factors. The pattern of the associated risk of cirrhosis was similar to that of HCC (all P value <0.001). The associated risk of cirrhosis for ALD increased to 4.74 (95% CI 4.08-5.52) when using non-SLD without cardiometabolic risk factors as a reference. DISCUSSION: This study highlights elevated risks of cirrhosis and HCC across various subtypes of SLD compared with non-SLD, emphasizing the importance of behavioral modifications for early prevention.

Hepatitis B relapse after entecavir or tenofovir alafenamide cessation under anti-viral prophylaxis for cancer chemotherapy.

BACKGROUND: No study has comparing hepatitis B virus (HBV) relapse rates among patients with both cancer and hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB) who completed anti-viral prophylaxis for chemotherapy and then stopped taking entecavir or tenofovir alafenamide (TAF). METHODS: A total of 227 HBeAg-negative cancer patients without cirrhosis who previously took entecavir (n = 144) or TAF (n = 83) for antiviral prophylaxis were enrolled. RESULTS: The cumulative incidence of virological and clinical relapse at 2 years was 37% and 10.4%, respectively, in the entecavir group, and 46.7% and 19.5%, respectively, in the TAF group. The multivariate analysis revealed that the use of hematologic malignancy, TAF use, and high-viremia group at baseline were independent risk factors for virological relapse, and use of rituximab, TAF use, higher FIB-4 index and high-viremia group at baseline were independent risk factors for clinical relapse. After propensity score-matching, the patients who discontinued TAF therapy still exhibited higher virological (P = 0.031) and clinical relapse rates (P = 0.012) than did those who discontinued entecavir therapy. The patients were allocated to high- (> 2000 IU/mL), moderate- (between 20 and 2000 IU/mL) and low- (< 20 IU/mL) viremia groups. In the high-viremia group, those who had taken TAF for antiviral prophylaxis had higher rates of virological and clinical relapse than did those who had taken entecavir; in the moderate- and low-viremia groups, no significant difference in virological and clinical relapse rates was detected between the entecavir and TAF groups. Three patients experienced hepatic decompensation upon clinical relapse. All three patients were lymphoma and underwent rituximab therapy. One patient developed acute on chronic liver failure and died even though timely retreatment. CONCLUSIONS: In patients with both cancer and CHB who underwent antiviral prophylaxis, TAF use was associated with a higher chance of HBV relapse than entecavir use after nucleos(t)ide analogue cessation, particularly in the high-viremia group. Patients who are hematologic malignancy and undergo a rituximab-containing cytotoxic therapy should be monitored closely after withdrawal from prophylactic NA treatment.

Prevalence, proportions of elevated liver enzyme levels, and long-term cardiometabolic mortality of patients with metabolic dysfunction-associated steatotic liver disease.

BACKGROUND AND AIM: This study estimated the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) according to cardiometabolic risk factors. The long-term impacts of MASLD on all-cause and cardiometabolic-specific mortality were evaluated. METHODS: We enrolled 343 816 adults aged ≥30 years who participated in a health screening program from 1997 through 2013. MASLD was identified on the basis of abdominal ultrasonography and metabolic profiles. The participants were further categorized by liver enzyme elevation. Baseline cardiometabolic comorbidities were classified on the basis of self-reported medication use and clinical seromarkers. All-cause and cardiometabolic-specific deaths were determined through computerized data linkage with nationwide death certifications until December 31, 2020. RESULTS: The overall prevalence of MASLD was 36.4%. Among patients with MASLD, 35.9% had abnormal liver enzyme levels. Compared with patients without MASLD, abnormal liver enzymes were positively associated with cardiometabolic comorbidities in patients with MASLD (Pfor trend < 0.001). After follow-up, patients with MASLD had a 9%-29% higher risk of all-cause, cardiovascular-related, or diabetes-related mortality. In the groups with MASLD and elevated and normal liver enzyme levels, the multivariate-adjusted hazard ratios for cardiovascular deaths were 1.14 (1.05-1.25) and 1.10 (1.03-1.17), respectively, and those for diabetes deaths were 1.42 (1.05-1.93) and 1.24 (0.98-1.57), respectively, compared with those in the non-MASLD group (Pfor trend < 0.001). DISCUSSION: Individuals with MASLD and elevated liver enzyme levels exhibited significantly higher risks of all-cause and cardiometabolic deaths and should be monitored and given consultation on cardiometabolic modifications.

Dual strategy involving hospital-based study and community-based screening to eliminate hepatitis C in remote areas.

BACKGROUND: /Purpose: To achieve the World Health Organization goal of eliminating viral hepatitis by 2030, a key strategy in resource-limited areas is to identify the areas with high prevalence and to prioritize screening and treatment intervention. We hypothesized that a hospital-based laboratory database could be used to estimate the township- and village-specific anti-hepatitis C virus (HCV) prevalence. METHODS: Yunlin County Public Health Bureau has been collecting anti-HCV test data from eight major hospitals. Township- and village-specific screening testing rates and anti-HCV prevalence were calculated for residents 40 years or older. A township with a wide range of anti-HCV prevalence rates was selected for outreach universal screening and for validating the village-specific prevalence of anti-HCV in the analysis of the data from the hospitals. RESULTS: The overall anti-HCV screening testing rate in Yunlin County was 30.4 %, whereas the anti-HCV prevalence rate for persons 40 years or older was 15.4 %. The village-specific anti-HCV prevalence rates ranged from 3.8 % to 85.8 %. Community-based screening was conducted in Kouhu Township. The village-specific anti-HCV prevalence rates ranged from 0 % to 18.8 %. Three of the four villages had the highest village-specific anti-HCV prevalence in the community-based study and the hospital-based study. Additionally, 95.8 % of the new HCV cases detected by universal screening received anti-HCV therapy. CONCLUSION: The hospital-based database provided a framework for identifying the villages with high anti-HCV prevalence. Additionally, community-based universal screening should be prioritized for villages with high prevalence in hospital-based databases.

Policy and Strategy for Hepatitis C Virus Elimination at the National Level: Experience in Taiwan.

The estimated prevalence of anti-HCV was 3.1% in Taiwan. Studies have shown iatrogenic behavior was the major transmission route. It is highest in specific populations including patients with end stage renal disease (ESRD), human immunodeficiency virus infection, who inject drug (PWID), and under opioid substitution treatment. Approximately 405,160 patients were seropositive for HCV RNA and in need of treatment. Taiwan government claims to reach WHO's 2030 goal of HCV elimination by 2025 and works hard to resolve several barriers of HCV elimination including political commitment, sustainable financing, minimize reimbursement restrictions, instituted monitoring, and perform micro-elimination of specific populations. The last stage of HCV elimination is to accelerate the universal HCV screening program of populations aged 45-79 years and resolve the unawareness issue of HCV infection. Hopefully, we can achieve the targets of HCV elimination set by WHO and reach the goal earlier in 2025.

Influence of Nonalcoholic Fatty Liver Disease With Increased Liver Enzyme Levels on the Risk of Cirrhosis and Hepatocellular Carcinoma.

BACKGROUND & AIMS: The influence of nonalcoholic fatty liver disease (NAFLD) on the long-term risk of cirrhosis and hepatocellular carcinoma (HCC) in Asian populations has not been widely investigated. METHODS: We enrolled 129,374 adults aged 30 years and older, all of whom participated in a health screening program from 2008 through 2013, were seronegative for hepatitis B surface antigen and anti-hepatitis C virus antibodies, and had limited daily alcohol consumption (<20 g/d for men and <10 g/d for women). Abdominal ultrasonography was performed to determine the presence of NAFLD. The participants were divided into the following groups: NAFLD with increased or normal liver enzyme levels, and non-NAFLD with normal liver enzyme levels. The incidences of cirrhosis and HCC were determined through computerized data linkage with nationwide registries. Cox proportional hazard models were used to estimate the hazard ratios of NAFLD on the risks of cirrhosis and HCC. RESULTS: The incidence rates of cirrhosis and HCC increased as follows: non-NAFLD with normal liver enzyme levels (n = 66,801; 51%), NAFLD with normal liver enzyme levels (n = 41,461; 32%), and NAFLD with increased liver enzyme levels (n = 21,112; 16%). In the NAFLD group with increased liver enzyme levels and the NAFLD group with normal liver enzyme levels, the corresponding multivariate-adjusted hazard ratios for cirrhosis were 3.51 (95% confidence interval [CI]: 2.36-5.22) and 0.73 (95% CI: 0.46-1.16), and for HCC were 1.91 (95% CI: 1.08-3.38) and 0.57 (95% CI: 0.31-1.04), respectively, compared with the non-NAFLD group (P for trend < .001). The findings were consistent after restricting the analysis to nonobese individuals (body mass index, <25 kg/m2) and nonobese individuals without diabetes (P < .05). CONCLUSIONS: Individuals with NAFLD and increased liver enzyme levels showed significantly higher risks for cirrhosis and HCC and should be monitored.

Combined baseline HBcrAg and end-of-treatment HBsAg predict HBV relapse after entecavir or tenofovir cessation.

BACKGROUND: For patients with chronic hepatitis B (CHB), the optimal stopping criteria for entecavir or tenofovir disoproxil fumarate treatment remain unclear. METHODS: This study recruited CHB patients with levels of hepatitis B surface antigen (HBsAg) <100 IU/mL at the end of treatment (EOT) from Kaohsiung (n = 190) and Linkou (n = 188) Chang Gung Memorial Hospitals for use as development and validation groups, respectively. RESULTS: In the development group, 108 patients with HBsAg ≤40 IU/mL were used for analysis of predictors of HBV relapse and HBsAg loss. Multivariate analysis showed that age, nucleos(t)ide analogue (NA)-experienced status, baseline hepatitis B core-related antigen (HBcrAg) and HBsAg at EOT were associated independently with virological and clinical relapse. An HBsAg level of 20 IU/mL at EOT was the best cut-off value for minimizing HBV relapse. Patients with EOT HBsAg ≤20 IU/mL had lower virological and clinical relapse rates and higher HBsAg loss rates than those with EOT HBsAg 21-40 IU/mL and HBsAg 41-100 IU/mL in the development and validation groups. The virological and clinical relapse rates were very low (5-year rates: 6.5% and 0%, respectively) and HBsAg loss rate was very high (5-year rate: 81.7%) in patients with a combination of baseline HBcrAg ≤4 log U/mL and EOT HBsAg ≤20 IU/mL in the development group. CONCLUSIONS: A combination of baseline HBcrAg ≤4 log U/mL and EOT HBsAg level ≤20 IU/mL might reduce the risk of HBV relapse and increase HBsAg loss rate, and might be helpful for off-NA follow-up strategy.

Usefulness of controlled attenuation parameter in monitoring clinically relevant decline of hepatic steatosis for non-alcoholic fatty liver disease.

BACKGROUND AND AIMS: Magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) is the reference standard of hepatic steatosis assessment. This study evaluates usefulness of controlled attenuation parameter (CAP) in monitoring the clinically relevant outcome by MRI-PDFF for non-alcoholic fatty liver disease (NAFLD) patients. METHODS: NAFLD patients were enrolled prospectively. Instruction was given in lifestyle modifications with exercise and control of metabolic factors. MRI-PDFF and CAP were performed at enrollment and follow-up, with the diagnostic validity of CAP in monitoring clinically relevant outcome defined as a decline of ≥30% relative to baseline value by MRI-PDFF. RESULTS: A total of 75 patients (male/female: 49/26, mean age: 53.2) were enrolled. Baseline MRI-PDFF, CAP and liver stiffness was 14.4%, 300.2 dB/m and 6.5 kPa. In a median interval of 369 days, thirteen (17.3%) patients achieved clinically relevant outcome with decline of 46.7 dB/m by CAP, compared with increase of 5.1 in the other patients. In multivariate analysis, clinically relevant outcome was associated with changes (Δ) of CAP and glucose. Assessed by area under receiver operating curve, the performances of ΔCAP in predicting clinically relevant outcome were 0.815 and 0.808, and with the specificity of >90%, the ΔCAP cutoff was -46 dB/m and -15% relative to baseline value; sensitivity was 53.8% and 46.2% with negative predictive value of 90.3% and 88.9% respectively. CONCLUSIONS: For NAFLD patients, CAP exhibited good performance in monitoring clinically relevant decline of hepatic steatosis in MRI-PDFF. With the cutoffs of -46 dB/m or -15%, ΔCAP is useful in excluding clinical relevant outcome achievement.

Retreatment Efficacy and Renal Safety of Tenofovir Alafenamide, Entecavir, and Tenofovir Disoproxil Fumarate After Entecavir or Tenofovir Cessation.

BACKGROUND: We aimed to compare the one-year retreatment efficacy and renal safety of entecavir, tenofovir disoproxil fumarate (TDF), and tenofovir alafenamide (TAF) after HBV relapse in patients who discontinued entecavir or TDF. METHODS: This retrospective study included 289 chronic hepatitis B (CHB) patients without cirrhosis who received entecavir (n = 93), TDF (n = 103), or TAF (n = 86) retreatment for at least 12 months after entecavir or TDF cessation. RESULTS: The rate of virological response (HBV DNA < 20 IU/mL) at 12 months of retreatment was 79/93 (84.9%) in the entecavir group, 92/103 (89.3%) in the TDF group, and 72/86 (83.7%) in the TAF group. The rate of ALT normalization (ALT ≤ 40 U/L) after 12 months of retreatment was 76/93 (81.7%) in the entecavir group, 77/103 (74.7%) in the TDF group , and 73/86 (84.9%) in the TAF group. There was no significant difference in the rates of virological response (p = 0.495) and ALT normalization (p = 0.198) among the three groups. Multivariate analysis showed that lower HBV DNA and HBsAg levels at baseline were independently associated with virological response at 12 months of retreatment. The TDF group (37.8 ± 34.8 U/L) had higher ALT levels at 12 months of retreatment than the TAF (27. ± 17.9 U/L, p = 0.015) and entecavir (28.3 ± 19.3 U/L, p = 0.022) groups. In patients with eGFR 60-90 mL/min/1.73 m2, eGFR change between baseline and 12 months of retreatment increased in the entecavir and TAF groups and decreased in the TDF group. CONCLUSIONS: TAF could be one of the retreatment options for retreatment of HBV relapse after entecavir or TDF cessation.

Seven centimeters as an optimal cutoff value for prognosis stratification in large monofocal hepatocellular carcinoma.

PURPOSE: Barcelona Clinic Liver Cancer (BCLC) guidelines designate monofocal hepatocellular carcinoma (HCC) > 2 cm as BCLC A, and large monofocal HCC is defined at > 5 cm. We aimed to evaluate the optimal cutoff value for large monofocal HCC based on prognosis stratification. METHODS: From 2011 to 2018, 3055 patients with newly diagnosed HCC, who were managed in our institution, including 868 patients with monofocal HCC > 2 cm and 330 patients with BCLC B, were enrolled in this retrospective study. RESULTS: Monofocal HCC > 5 cm patients had worse overall survival (OS) than monofocal HCC 2-5 cm patients (5-year OS: 54% vs. 57%; p = 0.047), confirmed by multivariate analysis (hazard ratio (HR): 1.492, 95% confidence interval (CI): 1.055-2.110; p = 0.024). Monofocal HCC > 5 cm patients had better OS than BCLC B HCC patients (5-year OS: 54% vs. 25%; p < 0.001), confirmed by multivariate analysis (HR: 0.670, 95% CI: 0.481-0.934; p = 0.018). Using 7 cm as the monofocal HCC cutoff value resulted in worse OS than monofocal HCC 2-7 cm (5-year OS: 50% vs. 57%; p = 0.02), confirmed by multivariate analysis (HR: 1.625, 95% CI: 1.039-2.540; p = 0.033). Monofocal HCC > 7 cm patients had better OS than BCLC B patients (p = 0.006). However, no significant difference was identified in the multivariate analysis (HR: 0.726; 95% CI: 0.473-1.115; p = 0.144). CONCLUSIONS: The prognosis of monofocal HCC > 7 cm was similar to that of BCLC B, indicating that 7 cm represents an optimal cutoff value for prognosis stratification in large monofocal HCC.

Three-Dimensional Speckle-Tracking Echocardiography to Evaluate Left Ventricular Function of Patients with Breast Cancer After Anthracycline Chemotherapy.

Objective: To explore the use of 3-dimensional speckle-tracking echocardiography (3DSTE) to evaluate changes in left ventricular function in patients with breast cancer after anthracycline chemotherapy. Methods: The clinical data of 30 patients with breast cancer diagnosed by pathology at The Third Affiliated Hospital of Qiqihar Medical University from December 2020 to December 2022 were collected for retrospective analysis. All patients received anthracycline chemotherapy, and serum cardiac troponin T (cTnT) concentrations were measured within 24 to 48 hours before chemotherapy and after 1 cycle and 4 cycles of chemotherapy. Then, conventional ultrasonography, routine echocardiography, and 3DSTE were performed to obtain dynamic images and parameters such as left ventricular global longitudinal strain, global area strain, global circumferential strain, global radial strain, and twist values. The myocardial comprehensive index was calculated to compare changes before and after anthracycline chemotherapy. A receiver operating characteristic curve was created for each parameter, and the areas under the curves were calculated. Results: Except for left ventricular end-diastolic diameter and end-diastolic interventricular septum thickness, the other conventional ultrasonography parameters differed at the 3 chemotherapy time points tested (all P < .001). The parameters as measured by 3DSTE decreased with an increased cumulative dose of anthracycline drugs, and the values differed at the different time points (all P < .001); the MCI value decreased the most. The serum cTnT concentrations of 9 patients after 4 cycles of chemotherapy were higher than the normal range, and the serum cTnT concentrations differed at the different chemotherapy time points (P < .001). Receiver operating characteristic curve analysis showed that the area under the curve value for MCI was higher than other quantitative parameters of imaging; for MCI, the area under the curve was 0.799, the Youden index was 0.683, the sensitivity was 77.80%, and the specificity was 90.50%. Conclusion: 3DSTE is helpful for early detection of damage to left ventricular function in patients with breast cancer treated with anthracycline drugs, and MCI is the most sensitive observation index among the parameters tested.

Earlier and Higher Rate of Hepatitis B Virus Relapse After Discontinuing Tenofovir Versus Entecavir in Hepatitis B e Antigen-Positive Patients.

BACKGROUND: This study investigated the incidence and predictors of hepatitis B virus (HBV) relapse in patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B who discontinued entecavir (ETV) or tenofovir disoproxil fumarate (TDF). METHODS: A total of 205 and 111 HBeAg-positive patients without cirrhosis who had stopped ETV or TDF treatment, respectively, for at least 6 months were recruited. RESULTS: In the entire cohort, patients with HBeAg seroconversion during treatment, and propensity score-matched patients, those who discontinued TDF had significantly higher rates of virological and clinical relapse than patients who discontinued ETV therapy. Multivariate analysis identified that TDF was independently associated with virological and clinical relapse in the entire cohort and subgroup analysis. Patients with HBeAg loss without anti-HBe antibody formation during treatment had significantly higher rates of off-therapy HBV relapse and HBeAg seroreversion than patients with HBeAg seroconversion during treatment. The hepatitis B core-related antigen (HBcrAg) level at end of treatment (EOT) was independently associated with HBV relapse and HBeAg seroreversion in all patients and patients with HBeAg seroconversion during treatment. CONCLUSIONS: TDF therapy, HBeAg loss without seroconversion during treatment, and higher HBcrAg levels at EOT are significant predictors of HBV relapse in HBeAg-positive patients who discontinued ETV or TDF.

Postdiagnosis Aspirin Use Associated With Decreased Biliary Tract Cancer-Specific Mortality in a Large Nationwide Cohort.

BACKGROUND AND AIMS: Biliary tract cancer (BTC) is rare and has limited treatment options. We aimed to examine aspirin use on cancer-specific survival in various BTC subtypes, including gallbladder cancer, ampulla of Vater cancer, and cholangiocarcinoma. APPROACH AND RESULTS: Nationwide prospective cohort of newly diagnosed BTC between 2007 and 2015 were included and followed until December 31, 2017. Three nationwide databases, namely the Cancer Registration, National Health Insurance, and Death Certification System, were used for computerized data linkage. Aspirin use was defined as one or more prescriptions, and the maximum defined daily dose was used to evaluate the dose-response relationship. Cox's proportional hazards models were applied for estimating HRs and 95% CIs. Analyses accounted for competing risk of cardiovascular deaths, and landmark analyses to avoid immortal time bias were performed. In total, 2,519 of patients with BTC were exposed to aspirin after their diagnosis (15.7%). After a mean follow-up of 1.59 years, the 5-year survival rate was 27.4%. The multivariate-adjusted HR for postdiagnosis aspirin users, as compared with nonusers, was 0.55 (95% CI: 0.51 to 0.58) for BTC-specific death. Adjusted HRs for BTC-specific death were 0.53 (95% CI: 0.48 to 0.59) and 0.42 (95% CI: 0.31 to 0.58) for ≤ 1 and > 1 maximum defined daily dose, respectively, and showed a dose-response trend (P < 0.001; nonusers as a reference). Cancer-specific mortality was lower with postdiagnosis aspirin use in patients with all major BTC subtypes. CONCLUSIONS: The nationwide study revealed that postdiagnosis aspirin use was associated with improved BTC-specific mortality of various subtypes. The findings suggest that additional randomized trials are required to investigate aspirin's efficacy in BTC.

Coix seed oil regulates mitochondrial functional damage to induce apoptosis of human pancreatic cancer cells via the PTEN/PI3K/AKT signaling pathway.

BACKGROUND: Coix seed oil (CSO) has a wide range of anticancer effects. However, the mechanism of action against pancreatic cancer (PC) and regulation of mitochondria in vitro is still unclear. MATERIALS AND RESULTS: This research investigated the possible mechanism of CSO induction of PC cell apoptosis and regulating mitochondrial functional damage. Proliferation of PC cells, mitochondrial membrane potential (MMP), qualitative and quantitative analysis of PC cell apoptosis, openness of mitochondrial permeability transition pore, related protein expression, generation of reactive oxygen species (ROS), and gene expression were determined by cell counting kit-8, JC-1 staining, acridine orange and ethidium bromide staining, flow cytometry, calcein-AM/cobalt staining, western blotting, dichlorofluorescein diacetate probe, and quantitative real-time reverse transcription-polymerase chain reaction, respectively. We confirmed that PTEN protein was involved in CSO-induced PANC-1 cell apoptosis and mitochondrial functional damage. CSO induced depolarization of MMP, increased opening of the mitochondrial permeability transition pore, increased ROS production, and further increased mitochondrial damage. Additionally, CSO downregulated expression of p-AKT and p-PI3K proteins; upregulated protein expression of cleaved caspase-9, Bax, cleaved caspase-3 and cytochrome c; and downregulated expression of Bcl-2 by upregulating the PTEN gene. The corresponding protein expression was consistent with the gene expression level. Furthermore, the loss of function of PTEN protein reduces the ability of CSO to induce apoptosis of PANC-1 cells and damage to mitochondrial function. CONCLUSIONS: CSO induces apoptosis of PANC-1 PC cells by modulating mitochondrial functional impairment and related apoptotic molecules via PTEN, which may be closely related to the PI3K/AKT signaling pathway.

Predictors of Virological Suppression After Clinical Relapse in Patients Who Discontinued Entecavir or Tenofovir.

BACKGROUND: The predictors of persistent virological suppression after clinical relapse remain unclear. AIMS: To investigate the predictors of retreatment or persistent virological suppression after clinical relapse in chronic hepatitis B (CHB) patients who discontinued entecavir or tenofovir disoproxil fumarate (TDF). METHODS: A total of 243 hepatitis B e antigen-negative CHB patients without cirrhosis who experienced clinical relapse after entecavir or TDF cessation were enrolled. RESULTS: Of the 243 CHB patients, 192 received retreatment and 51 did not receive retreatment after clinical relapse. Of the 51 patients without retreatment, 23 achieved persistent virological suppression (persistent HBV DNA < 2000 IU/mL at least 2 years) and 10 experienced hepatitis B surface antigen (HBsAg) loss. The Cox regression analysis showed that short consolidation duration, short duration of the first clinical relapse from the end of treatment (EOT), and high bilirubin and HBV DNA levels at the first clinical relapse were independent predictors of retreatment. Long duration of the first clinical relapse from the EOT and low HBsAg levels at the first clinical relapse were independent factors of patients with persistent virological suppression. The rates of persistent virological suppression at the first clinical relapse among patients with HBsAg < 100 and ≥ 100 IU/mL were 44.4% (12/27) and 5.1% (11/216) (P < 0.001), respectively. Baseline HBsAg levels and no retreatment requirement were independent factors associated with HBsAg loss. CONCLUSIONS: The HBsAg of 100 IU/mL at the first clinical relapse could predict persistent virological suppression after clinical relapse in patients who discontinued entecavir or TDF therapy.

The characteristics of patients with macrovascular invasion in hepatocellular carcinoma: when East meets West.

PURPOSE: To evaluate the prevalence and extension of macrovascular invasion (MaVI) in a large cohort of hepatocellular carcinoma (HCC) patients and analyze the association between MaVI and overall survival (OS). METHODS: From 2011 to 2018, 2540 patients with newly diagnosed HCC who were managed in our institution were enrolled in this retrospective study. Tumor invasion of the intrahepatic branches of the portal or hepatic veins was defined as peripheral MaVI. Tumor invasion of the main portal vein or inferior vena cava was defined as central MaVI. RESULTS: MaVI prevalence was 16.2% (n = 411). Among patients with Barcelona Clinic Liver Cancer (BCLC) stage C and Child-Pugh class A, 165 patients presented with peripheral MaVI and 89 patients with central MaVI. The median OS was 13.2 months (95% confidence interval [CI]: 11.4-15.4) in the peripheral MaVI group and 6.6 months (95% CI: 3.6-9.5) in the central MaVI group (p < 0.001). In patients with BCLC stage C and Child-Pugh class B or BCLC stage D, 68 patients presented with peripheral MaVI and 89 patients with central MaVI. The median OS was 3.6 months (95% CI: 3.1-4.2) in the peripheral MaVI group and 2.8 months (95% CI: 2.1-3.4) in the central MaVI group (p = 0.674). CONCLUSION: The extension of MaVI significantly affected patient survival only in those with BCLC stage C and Child-Pugh class A. In patients with BCLC stage C and Child-Pugh class B or BCLC stage D, survival was poor irrespective of MaVI status.

Community-based screening by Anti-HCV reflex HCV Ag test and accessible post-screening care toward elimination of hepatitis C in two hyperendemic townships.

BACKGROUND: Hyperendemic townships of hepatitis C virus (HCV) infection should devote extra efforts to eliminate HCV. We aimed to evaluate efficacy of the screening and linkage to care in two HCV hyperendemic townships. METHODS: Village-to-village HCV screening using anti-HCV reflex HCV Ag test was conducted in two HCV hyperendemic rural townships (Lioujiao and Yijhu). All residents aged 30 years or older were invited. Those patients detected as infected were referred to nearby hospitals or clinics in Lioujiao and to an accessible outreach hepatology clinic in Yijhu. RESULTS: The populations of Lioujiao and Yijhu townships at time of survey were 18,389 and 14,787 with 6086 (33.1%) and 4604 (31.1%) having ever been previously screened, and 1517 and 1071 responded to this screening respectively. Their crude screening coverage rates were 41.5% and 38.5%, and adjusted screening coverage rates were 54.3% and 94.6% respectively. The prevalence rates of anti-HCV and HCV Ag were 17.9% and 11.9% in Lioujiao, and 9.2% and 5.6% in Yijhu respectively, with their rates of antigenemia (HCV Ag/anti-HCV) being 62.1% and 60.6% respectively. Numbers needed to test (NNT) to find a candidate for anti-viral treatment were 9 and 18. For linkage to care, treatment rate by referral (Lioujiao) was slightly lower than by accessible outreach hepatology clinic (Yijhu) (84.9% vs. 93.3%, p = 0.093). Overall successful sustained virological response rate at week 12 was 98.2% (161/164) in outreach hepatology clinic. CONCLUSION: Since NNT was low, it was worthwhile conducting intensive screening in these hyperendemic townships. For high treatment rate, accessible outreach hepatology clinic is feasible especially in areas without adequate medical resources.

Incorporating albumin-bilirubin grade and up-to-seven criteria to predict outcomes of patients with intermediate stage hepatocellular carcinoma after transarterial (chemo)embolization.

BACKGROUND/PURPOSE: This study is to use albumin-bilirubin (ALBI) grade and up-to-7 (UT7) criteria to assess outcomes of patients with intermediate stage hepatocellular carcinoma (HCC) after transarterial (chemo)embolization (TA(C)E). METHODS: Between January 2012 and January 2019, newly diagnosed intermediate HCC patients underwent TA(C)E were enrolled and analyzed. The demographics, clinical characteristics and survival were obtained from medical chart reviews. RESULTS: A total of 359 patients were enrolled and 30.4% of them were within UT7 criteria (UT7 (-)). There were 36.5%, 59.3%, and 4.2% of the patients with ALBI grade I, II, and III, respectively. Beyond UT7 (UT7 (+)) and ALBI grade II/III were associated with overall mortality in multivariate analysis. Based on ALBI grade I/II/III and UT7 -/+, patients were classified into six groups as ALBI grade I plus UT7 (-), II plus UT7 (-), III plus UT7 (-), I plus UT7 (+), II plus UT7 (+), and III plus UT7(+). Distributions of median survival were 47.5, 32.9, 15, 34.3, 16.7 and 14.3 months, respectively. Patients with statistically insignificant survivals were further combined. Patients with ALBI grade I plus UT7 (-) were reclassified as ALBI-U class I, whereas ALBI grade II plus UT7 (-) and I plus UT7 (+) were ALBI-U class II, and the others were ALBI-U class III. There were 8.4%, 48.7%, and 42.9% of patients in ALBI-U class I, II, and III, respectively. The 5-year survival rate was 48.8%, 22.5%, and 13.7% in ALBI-U class I, II, and III, respectively (p < 0.01). CONCLUSION: ALBI-U classification was useful in predicting outcomes of patient with intermediate stage HCC after TA(C)E.

Reappraisal of the roles of alpha-fetoprotein in hepatocellular carcinoma surveillance using large-scale nationwide database and hospital-based information.

BACKGROUND/PURPOSE: Controversies over the use of alpha-fetoprotein (AFP) for detection of hepatocellular carcinoma (HCC) existed from guidelines. Using large-scale database and hospital-based information, we aimed to reappraise the role of AFP in HCC surveillance, including proportion of AFP elevation by stage of HCC, additional benefit of AFP in combination of ultrasonography (US) in the detection of early HCC, and survival in early HCC with high AFP levels. METHODS: This retrospective study enrolled 43,437 patients from database of the Taiwan Cancer Registry (TCR) and 4250 patients from Kaohsiung Chang Gung Memorial Hospital (KCGMH) between January 2011 and December 2017. RESULTS: The HCC cases in KCGMH accounted for 9.8% of the total cases in the TCR. Among both nationwide database and hospital-based information, the proportion of early HCC patients with an AFP level of ≥20 ng/mL was approximately 40%. In KCGMH, the proportion of patients with an AFP level of ≥20 ng/mL and a virus-related (hepatitis B and C) etiology was around 41.7%; furthermore, among patients with early HCC, those with an AFP level of ≥20 ng/mL had 4.7 years of median survival and 48.3% of the 5-year overall survival rate. By hospital electronic medical records review of early HCC cohort in KCGMH, approximately 10.9% of patients with AFP levels ≥20 ng/mL had US-undetectable early HCC. CONCLUSION: This study suggested that AFP in combination with US would add an additional benefit as being a prompted role for detection of early HCC in patients with US-undetectable HCC.
