We prospectively investigated the changes of liver stiffness (LS) and the occurrence of hepatocellular carcinoma (HCC) after hepatitis C virus (HCV) eradication using direct antiviral agents (DAA) over three years. LS measurement using transient elastography and serum fibrosis surrogate markers before treatment and at 48, 96, 144 weeks after starting direct-acting antivirals (DAA) according to the protocol were evaluated. Patients were also compared with historical cohort treated with pegylated interferon (peg-IFN). Sustained viral response (SVR) was observed in 95.8%. LS value in the patients achieving SVR significantly decreased over time (19.4 ± 12.9 kPa [baseline], 13.9 ± 9.1 kPa [48 weeks], 11.7 ± 8.2 kPa [96 weeks], 10.09 ± 6.23 [144 weeks], all p  < 0.001). With matched analysis, the decrease in LS value was significantly larger in DAA group than peg-IFN group at both 48 weeks (29% vs. 9%) and 96 weeks (39% vs. 17%). The incidence of HCC was not significantly different between DAA and peg-IFN groups (5.5% vs. 5.4%) at 144 weeks. HCV eradication with DAA can lead to improvement of liver stiffness over time. The regression of fibrosis was greater in the group with DAA than peg-IFN. Clinical trials registration: ClinicalTrials.gov (NCT02865369).

Frailty is a known risk factor for major life-threatening liver transplant complications, deaths, and waitlist attrition. Whether frailty indicates risk for adverse outcomes in cirrhosis short of lethality is not well defined. We hypothesized that clinical measurements of frailty using gait speed and grip strength would indicate the risk of subsequent hospitalization for the complications of cirrhosis. We assessed frailty as gait speed and grip strength in a 1-year prospective study of 373 cirrhotic patients evaluated for or awaiting liver transplantation. We determined its association with the outcome of subsequent hospital days/100 days at risk for 7 major complications of cirrhosis. We tested potential covariate influences of Model for Endstage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP) scores, age, sex, height, depression, narcotic use, vitamin D deficiency, and hepatocellular carcinoma using multivariable modeling. Patients experienced 2.14 hospital days/100 days at risk, or 7.81 days/year. Frailty measured by gait speed was a strong risk factor for hospitalization for all cirrhosis complications. Each 0.1 m/s gait speed decrease was associated with 22% greater hospital days (P<0.001). Grip strength showed a similar but nonsignificant association. Gait speed remained independently significant when adjusted for MELD, CTP, and other covariates. At hospital costs of $4,000/day, patients with normal 1 m/s gait speed spent 6.2 days and $24,800/year; patients with 0.5 m/s speed spent 21.2 days and $84,800/year; and patients with 0.25 m/s speed spent 40.2 days and $160,800/year. Frailty as measured by gait speed is an independent and potentially modifiable risk factor for cirrhosis complications requiring hospitalization. The potential clinical value of frailty measurements to help define such risk merits broader evaluation.

Background The influence of hepatic steatosis (HS) on liver metastasis in patients with non-metastatic breast cancer (BC) remains unclear. The aim of this study was to clarify the relationship between HS and liver metastasis in non-metastatic BC patients. Methods Patients who underwent treatment for BC at two affiliated hospitals of Southern Medical University, between January 1, 2005 and December 31, 2015, were retrospectively reviewed. BC patients were divided into the study and control groups based on the presence of HS. The association between HS and liver metastasis was analyzed, adjusting for the confounding factors using Cox regression and propensity score case - match analysis . Results In total, 1230 female BC patients were included, and 372 (30.2%) patients were diagnosed with HS (at the time of diagnosis BC or before). The cumulative liver metastasis-free survival (MFS) rate was significantly higher in the study group than in the control group (hazard ratio 0.61; 95% confidence interval 0.40–0.94; P  = 0.024). On multivariate analysis, HS was an independent protective factor for local liver metastasis (HR 0.55; 0.35–0.86; P  = 0.008). After one - to - one matching of the study group (344) with the control group (344), liver MFS remained significantly better in the study group (HR 0.42; 0.26–0.69; P  = 0.001). Conclusion This study indicated that HS may serve as an independent factor to decrease liver metastasis in patients with BC. Additional prospective studies are necessary to validate this finding.

Neonatal hepatitis B vaccination has been implemented worldwide to prevent hepatitis B virus (HBV) infections. Its long-term protective efficacy on primary liver cancer (PLC) and other liver diseases has not been fully examined. The Qidong Hepatitis B Intervention Study, a population-based, cluster randomized, controlled trial between 1985 and 1990 in Qidong, China, included 39,292 newborns who were randomly assigned to the vaccination group in which 38,366 participants completed the HBV vaccination series and 34,441 newborns who were randomly assigned to the control group in which the participants received neither a vaccine nor a placebo. However, 23,368 (67.8%) participants in the control group received catch-up vaccination at age 10-14 years. By December 2013, a total of 3,895 (10.2%) in the vaccination group and 3,898 (11.3%) in the control group were lost to follow-up. Information on PLC incidence and liver disease mortality were collected through linkage of all remaining cohort members to a well-established population-based tumor registry until December 31, 2013. Two cross-sectional surveys on HBV surface antigen (HBsAg) seroprevalence were conducted in 1996-2000 and 2008-2012. The participation rates of the two surveys were 57.5% (21,770) and 50.7% (17,204) in the vaccination group and 36.3% (12,184) and 58.6% (17,395) in the control group, respectively. Using intention-to-treat analysis, we found that the incidence rate of PLC and the mortality rates of severe end-stage liver diseases and infant fulminant hepatitis were significantly lower in the vaccination group than the control group with efficacies of 84% (95% CI 23%-97%), 70% (95% CI 15%-89%), and 69% (95% CI 34%-85%), respectively. The estimated efficacy of catch-up vaccination on HBsAg seroprevalence in early adulthood was 21% (95% CI 10%-30%), substantially weaker than that of the neonatal vaccination (72%, 95% CI 68%-75%). Receiving a booster at age 10-14 years decreased HBsAg seroprevalence if participants were born to HBsAg-positive mothers (hazard ratio [HR]  = 0.68, 95% CI 0.47-0.97). Limitations to consider in interpreting the study results include the small number of individuals with PLC, participants lost to follow-up, and the large proportion of participants who did not provide serum samples at follow-up. Neonatal HBV vaccination was found to significantly decrease HBsAg seroprevalence in childhood through young adulthood and subsequently reduce the risk of PLC and other liver diseases in young adults in rural China. The findings underscore the importance of neonatal HBV vaccination. Our results also suggest that an adolescence booster should be considered in individuals born to HBsAg-positive mothers and who have completed the HBV neonatal vaccination series.

PurposeRadioembolization has emerged as a treatment modality for patients with primary and secondary liver tumours. This observational study CIRT-FR (CIRSE Registry for SIR-Spheres Therapy in France) aims to evaluate real-life clinical practice on all patients treated with transarterial radioembolization (TARE) using SIR-Spheres yttrium-90 resin microspheres in France. In this interim analysis, safety and quality of life data are presented. Final results of the study, including secondary effectiveness outcomes, will be published later. Overall, CIRT-FR is aiming to support French authorities in the decision making on reimbursement considerations for this treatment.MethodsData on patients enrolled in CIRT-FR from August 2017 to October 2019 were analysed. The interim analysis describes clinical practice, baseline characteristics, safety (adverse events according to CTCTAE 4.03) and quality of life (according to EORTC QLQ C30 and HCC module) aspects after TARE.ResultsThis cohort included 200 patients with hepatocellular carcinoma (114), metastatic colorectal cancer (mCRC; 38) and intrahepatic cholangiocarcinoma (33) amongst others (15). TARE was predominantly assigned as a palliative treatment (79%). 12% of patients experienced at least one adverse event in the 30 days following treatment; 30-day mortality was 1%. Overall, global health score remained stable between baseline (66.7%), treatment (62.5%) and the first follow-up (66.7%).ConclusionThis interim analysis demonstrates that data regarding safety and quality of life generated by randomised-controlled trials is reflected when assessing the real-world application of TARE.Trial RegistrationClinical Trials.gov NCT03256994.

Hepatitis B Virus (HBV) is one of the most common human infectious agents, and the mutations in its genome may cause chronic hepatitis (CH), liver cirrhosis (LC), and hepatocellular carcinoma (HCC). This study was designed to characterize the enhancer-II (Enh-II) region of X gene in HBV positive patients to assess the association of such mutations with CH, LC, and HCC. HBV positive samples (N = 200) with patients' demographic and clinical data were collected from different regions of Khyber Pakhtunkhwa (KP), Pakistan. The Enh-II region of the HBx gene was sequenced and zanalyzed for polymorphism associated with advanced liver disease. Univariate and logistic regression analyses were performed to evaluate potent mutations associated with a risk for LC and HCC. HBV Enh-II region sequences analysis revealed 25 different mutations. The highest frequency of mutations S101F (62.2%), A102V/R/G/I (56.25%), M103L/A (68.75%)were found in HCC, followed in LC and CH patients as 57.1%, 42.8%, 28.52% 16%, 15.2% and 18.4% respectively. H94 deletion in the α-box of the Enh-II region, associated with a high risk of HCC was found in half of the HCC patients. This deletion was present in 28.5% of LC and 6.5% of CH patients. Importantly, the high frequency of some notable mutations such as E109A/Y, A110S/K, Y111D/E, and F112L was first time reported in the entire study population. The frequencies of these mutations were high in HCC (43.75%, 37.5%, 50% and 43.75% respectively) as compared to LC (14.28%, 14.28%, 28.2% and 42.8%) and CH patients (12.8%, 15.2%, 16.8% and 16% respectively). Mutations associated with LC and HCC are prevalent in the Enh-II region in Pakistani HBV isolates. The mutations found are alarming in CH patients as these may progress to LC and HCC in a large number of patients.

Hepatectomy and transplantation are the main surgical therapies for HCC patients, and radiotherapy or chemotherapy is often used as adjuvant treatment. Researches have evaluated the independent predictors of HCC, but evidence for factors predicting the efficacy of chemotherapy is rare. Patients diagnosed with HCC between 2010 and 2015 from the SEER database were included and randomly divided into non-chemotherapy and chemotherapy groups. The predictors of CSS and OS were analyzed with the Cox proportional-hazards regression model and Fine and Gray’s competing risk model. Although there was no significant difference in survival analysis between the chemotherapy and non-chemotherapy groups, the cumulative cancer-specific mortality of most HCC patients was decreased in the chemotherapy group. AJCC stage, tumor size, grade, surgery and radiotherapy were predictors of OS and CSS in the non-chemotherapy group, while AJCC stage, tumor size, AFP, grade and surgery in the chemotherapy group. Surgery combined with chemotherapy was applicable to all AJCC stage patients. Surgery was the major treatment option for patients in AJCC I and AJCC II stage, and chemotherapy in AJCC III and AJCC IV stage. In conclusion, the study provided population-based estimates of the prognostic factors in HCC patients with or without chemotherapy.

Background Long-term antiviral therapy has resulted in viral suppression and biochemical response in chronic hepatitis B, although the risk of hepatocellular carcinoma has not been abolished. The Page-B score could be useful to estimate the probability of HCC. Aims To analyze the effectiveness and safety of entecavir or tenofovir for more than 4 years and the usefulness of Page-B score in the real-world setting. Methods Analysis of Caucasian chronic hepatitis B subjects treated with entecavir or tenofovir from the prospective, multicenter database CIBERHEP. Results A total of 611 patients were enrolled: 187 received entecavir and 424 tenofovir. Most were men, mean age 50 years, 32% cirrhotic and 16.5% HBeAg-positive. Mean follow-up was 55 (entecavir) and 49 (tenofovir) months. >90% achieved HBV DNA <69 IU/mL and biochemical normalization by months 12 and 36, respectively. Cumulative HBeAg loss and anti-HBe seroconversion were achieved by 33.7 and 23.8%. Four patients lost HBsAg; three HBeAg-positive. Renal function remained stable on long-term follow-up. Fourteen (2.29%) developed HCC during follow-up all of them with baseline Page-B ≥10. Nine were diagnosed within the first 5 years of therapy. This contrasts with the 27 estimated by Page-B, a difference that highlights the importance of regular HCC surveillance even in patients with virological suppression. Conclusions Entecavir and tenofovir achieved high biochemical and virological response. Renal function remained stable with both drugs. A Page-B cut-off ≥10 selected all patients at risk of HCC development.

Background Early tumor recurrence after curative resection typically indicates a poor prognosis. The objective of the current study was to investigate the risk factors, treatment, and prognosis of early recurrence of neuroendocrine tumor (NET) liver metastasis (NELM) after hepatic resection. Methods A total of 481 patients who underwent curative-intent resection for NELM were identified from a multi-institutional database. Data on clinicopathological characteristics, intraoperative details, and outcomes were documented. The optimal cutoff value to differentiate early and late recurrence was determined to be 3 years based on linear regression. Results With a median follow-up of 60 months, 223 (46.4%) patients developed a recurrence, including 158 (70.9%) early and 65 (29.1%) late recurrences. On multivariable analysis, pancreatic NET, primary tumor lymph node metastasis, and a microscopic positive surgical margin were independent risk factors for early intrahepatic recurrence. While recurrence patterns and treatments were comparable among patients with early and late recurrences, early recurrence was associated with worse disease-specific survival than late recurrences (10-year NELM-specific survival, 44.5 vs 75.8%, p  < 0.001). Among the 34 (21.5%) patients who underwent curative treatment for early recurrence, post-recurrence disease-specific survival was better than non-curatively treated patients (10-year NELM-specific survival, 54.2 vs 26.3%, p  = 0.028), yet similar to patients with late recurrences treated with curative intent (10-year NELM-specific survival, 54.2 vs 37.4%, p  = 0.519). Conclusions Early recurrence after surgery for NELM was associated with the pancreatic type, primary lymph node metastasis, and extrahepatic disease. Re-treatment with curative intent prolonged survival after recurrence, and therefore, operative intervention even for early recurrences of NELM should be considered.

BackgroundProgressive hepatic fibrosis leads to hepatocellular carcinoma (HCC) and decompensated cirrhosis. The aim of this study was to identify the high-risk population for progressive hepatic fibrosis and the incidence of HCC and decompensated cirrhosis in chronic hepatitis B (CHB) patients with antiviral therapy.MethodsThe data came from a multicenter, center-randomized, double-blind clinical trial that analyzed only patients in the ETV-treated arm. There was 156 hepatitis B e antigen (HBeAg)-positive and 135 HBeAg-negative patients in 14 institutions. The primary endpoint was fibrosis reversal on 72-week Entecavir (ETV) treatment. The 7-year cumulative incidence of HCC and decompensated cirrhosis were analyzed. Multivariate logistic and LASSO regression analyses were used to screen variables associated with fibrosis reversal.Results86/156 (55%) HBeAg-positive and 58/135 (43%) HBeAg-negative patients achieved fibrosis reversal on 72-week ETV treatment. Average age was 43 years, 203 (69.8%) was male, and 144 (49.5%) patients had cirrhosis. Age ≥ 40 years (OR: 0.46, 95% CI 0.23–0.93) and HBcrAg ≥ 8.23 log U/ml (OR: 2.72, 95% CI 1.33–5.54) in HBeAg-positive patients and HBV genotype C (OR: 0.44, 95% CI 0.21–0.97) in HBeAg-negative patients were independent factors of fibrosis reversal. It was confirmed in patients with cirrhosis. After 7-year ETV treatment, seven (4.5%) HBeAg-positive patients occurred HCC or decompensated cirrhosis, including four patients with age ≥ 40 years and six with HBcrAg 8.23log U/ml, while twelve (8.9%) HBeAg-negative patients occurred, including eleven with HBV genotype C.ConclusionsHBeAg-positive patients with a low HBcrAg level or old age, and HBeAg-negative patients with HBV genotype C tended to develop progressive hepatic fibrosis and had a high incidence of HCC and decompensated cirrhosis, even on ETV treatment.
