Application and Impact of Antiviral Therapy for Patients with HBV-Related Hepatocellular Carcinoma Receiving Sorafenib and Lenvatinib Treatment.

Overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC) has improved in the era of multi-line sequential therapy. The application of antiviral therapy and its impact on survival for patients with HBV-related HCC needs to be reassessed. The aim of this study was to evaluate the application and impact of antiviral therapy on survival for patients with HBV-related HCC receiving tyrosine kinase inhibitor (TKI) therapy. Patients with advanced HBV-related HCC treated with sorafenib or lenvatinib as first-line therapy with (n = 377) and without (n = 182) nucleos(t)ide analogue (NUC) therapy were retrospectively enrolled. Prognostic factors of OS were evaluated. Secular trends in the increased application of NUC therapy and improved survival were observed in the last decade. The HBV reactivation rate in patients without NUC therapy was 6.6%. By multivariate analysis, baseline low HBV viral load, achieving undetectable HBV DNA after TKI therapy, and ability to receive second-line therapy were found to be independent predictors of OS. In subgroup patients with NUC therapy, starting NUC before TKI was associated with a better OS. In conclusion, the application of antiviral therapy for patients with HBV-related HCC receiving TKI therapy has increased over time. Achieving complete virological suppression may contribute to a better OS in patients with advanced HBV-related HCC.

Anti-PD-1 combined sorafenib versus anti-PD-1 alone in the treatment of advanced hepatocellular cell carcinoma: a propensity score-matching study.

BACKGROUND: Vascular endothelial growth factor (VEGF) plays a role in the tumor microenvironment. Sorafenib, which inhibits the VEGF pathway, has an immune-modulation function but lacks substantial clinical data. This study aims to explore the efficacy of anti-PD-1 combined sorafenib in advanced hepatocellular carcinoma (HCC). METHODS: HCC patients who underwent anti-PD-1 treatment at Taipei Veterans General Hospital (Taipei, Taiwan) between January 2016 and February 2019 were reviewed. The efficacy was compared between groups after propensity-score matching. RESULTS: There were 173 HCC patients receiving anti-PD-1. After excluding unsuitable cases, 140 patients were analyzed, of which 58 received combination therapy and 82 received anti-PD-1 alone. The combination therapy had a trend of higher CR rate (8.6% vs. 4.9%, ns.), ORR (22.4% vs. 19.5%, ns.) and significantly higher DCR (69.0% vs. 37.8%, p < 0.05) comparing to anti-PD-1 alone. After matching, combination group achieved longer progression-free survival (3.87 vs. 2.43 months, p < 0.05) and overall survival (not reached vs. 7.17 months, p < 0.05) than anti-PD-1 alone, without higher grade 3/4 AE (10.3% vs. 7.1%, p = 0.73). The tumor response varied among different metastatic sites, with high responses in adrenal glands, peritoneum and lungs. The more AFP declined (> 10, > 50 and > 66%), the higher the ORR (70, 80 and 92%) and CR rates (30, 35 and 58%) were achieved at day 28. CONCLUSIONS: This is the first study to demonstrate the combination of anti-PD-1 and sorafenib had better efficacy and survival benefit. A prospective randomized study is needed to confirm this finding.

Herbal and dietary supplement-induced liver injury in Taiwan: comparison with conventional drug-induced liver injury.

BACKGROUND AND AIMS: Whether herbal and dietary supplements (HDS) are safer than Western conventional drugs is controversial. The aim of this study was to explore the characteristics and risk factors for HDS-induced liver injury (HILI) in Taiwan. METHODS: This is a 9-year multi-center prospective study conducted in Taiwan from 2011 to 2019. Patients with HILI were compared to those with conventional drug-induced liver injury (CILI). RESULTS: A total of 1,297 patients were enrolled, of whom 285 (22.0%) had HILI and 1,012 (78.0%) had CILI. Compared to the CILI group, the HILI group had higher initial serum alanine aminotransferase, alkaline phosphatase (ALP), peak ALP and bilirubin levels, and higher rates of jaundice, ascites, encephalopathy, coagulopathy, sepsis and acute liver failure. In addition, the HILI group had a higher mortality rate than the CILI group (12.6 vs. 8.0%, p = 0.016). Hepatitis B carrier status, elevated baseline liver biochemical tests and the use of crude herbs (without processing) were associated with an increased risk of HILI-related mortality (adjusted hazard ratios [95% confidence intervals]: 2.90 [1.43-5.99], 2.40 [1.01-5.68] and 2.94 [1.45-5.97], respectively). CONCLUSIONS: HDS are popular and incriminated in more than one-fifth of drug-induced liver injuries in Taiwan. The patients with HILI were more severe than those with CILI in terms of liver biochemical tests, complications and mortality. Hepatitis B carriers, those with elevated baseline liver tests and crude herb users may have a higher risk of HILI-related mortality. The prudent use of HDS is suggested in these high-risk subjects.

(Pro)renin Receptor Knockdown Attenuates Liver Fibrosis Through Inactivation of ERK/TGF-ß1/SMAD3 Pathway.

BACKGROUND & AIMS: Activation of the (pro)renin receptor (PRR) up-regulates the expression of profibrotic genes in the kidney and heart. We aimed to investigate the role of PRR in hepatic fibrogenesis. METHODS: Human hepatic PRR levels were measured in patients with or without liver fibrosis. PRR expression was analyzed in primary mouse hepatic stellate cells (HSCs). Experimental fibrosis was studied in thioacetamide (TAA)-treated or methionine choline-deficient (MCD) diet-fed C57BL/6 mice. Lentivirus-mediated PRR short hairpin RNA was used to knockdown hepatic PRR expression. Lentiviral vectors expressing PRR short hairpin RNA or complementary DNA from the α-smooth muscle actin promoter were used for myofibroblast-specific gene knockdown or overexpression. RESULTS: PRR is up-regulated in human and mouse fibrotic livers, and in activated HSCs. Hepatic PRR knockdown reduced liver fibrosis by suppressing the activation of HSCs and expression of profibrotic genes in TAA or MCD diet-injured mice without significant changes in hepatic inflammation. Renin and prorenin increased the expression of PRR and production of TGF-ß1 in human activated HSC Lieming Xu-2 cells, and knockdown of PRR inactivated Lieming Xu-2 cells with decreased production of transforming growth factor (TGF)-ß1 and Mothers against decapentaplegic homolog 3 (Smad3) phosphorylation. Myofibroblast-specific PRR knockdown also attenuated liver fibrosis in TAA or MCD diet-injured mice. Mice with both myofibroblast-specific and whole-liver PRR knockdown showed down-regulation of the hepatic extracellular signal-regulated kinase (ERK)/TGF-ß1/Smad3 pathway. Myofibroblast-specific PRR overexpression worsened TAA-induced liver fibrosis by up-regulating the ERK/TGF-ß1/Smad3 pathway. CONCLUSIONS: PRR contributes to liver fibrosis and HSC activation, and its down-regulation attenuates liver fibrosis through inactivation of the ERK/TGF-ß1/Smad3 pathway. Therefore, PRR is a promising therapeutic target for liver fibrosis.

Pre-sarcopenia determines post-progression outcomes in advanced hepatocellular carcinoma after sorafenib failure.

Many second-line therapies are recently approved for patients with advanced hepatocellular carcinoma (HCC), in whom protein malnutrition is prevalent that would affect treatment outcomes. In this study, we aimed to investigate the role of pre-sarcopenia and muscle restoration in patients with sorafenib-failed advanced HCC. From August 2012 to March 2017, 385 patients who developed radiology-proven HCC progression after sorafenib treatment were enrolled in the study. Pre-sarcopenia is defined as transverse psoas muscle thickness per body height < 16.8 mm/m, which was prevalent (64.7%) in our patients. Age > 60 years, female gender, and body mass index < 22 kg/m2 were independent predictors to the development of pre-sarcopenia. Patients with muscle depletion had significantly worse post-progression survival (PPS) compared with their counterparts (median PPS: 3.8 vs. 5.8 months, p = 0.003), particularly in those with intermediate liver reserves (Child-Pugh class B or Albumin-bilirubin grade 2). Besides, pre-sarcopenia independently predicted post-progression mortality in sorafenib-failed HCC (hazard ratio: 1.340, p = 0.012). In patients who developed pre-sarcopenia before sorafenib treatment, muscle restoration was associated with a longer PPS compared with their counterparts (6.3 vs. 3.6 months, p = 0.043). In conclusion, pre-sarcopenia independently determined the outcomes of sorafenib-failed HCC. Nutrition support to restore muscle mass would prolong survival for higher-risk patients.

Obeticholic acid ameliorates hepatorenal syndrome in ascitic cirrhotic rats by down-regulating the renal 8-iso-PGF2α-activated COX-TXA2 pathway.

BACKGROUNDS/AIMS: The present study explores the potential of chronic treatment with the Foresaid X receptor (FXR) agonist obeticholic acid (OCA), which inhibits oxidative stress-related pathogenesis, in ascitic cirrhotic rats with hepatorenal syndrome (HRS) developed 6 weeks after bile duct ligation (BDL). METHODS: Systemic, splanchnic, and renal hemodynamics and pathogenic cascades were measured in ascitic BDL and sham rats receiving 2-weeks of either vehicle or OCA treatments (sham-OCA and BDL-OCA groups), and NRK-52E cells, rat kidney tubular epithelial cells. RESULTS: Chronic OCA treatment significantly normalized portal hypertension, glomerular filtration rate, urine output, renal blood flow; decreased ascites, renal vascular resistance, serum creatinine, and the release of renal tubular damage markers, including urinary neutrophil gelatinase-associated lipocalin (uNGAL) and kidney injury moleculae-1 (uKim-1) in BDL-OCA rats. In the BDL group, inhibition of the renal oxidative stress (8-iso-PGF2α)-activated cyclooxygenase-thromboxane A2 [COX-TXA2] pathway, apoptosis, and tubular injury accompanied by a decrease in hyper-responsiveness to the vasoconstrictor 8-iso-PGF2α in perfused kidneys. In vitro experiments revealed that 8-iso-PGF2α induced oxidative stress, release of reactive oxygen species, and cell apoptosis, which were reversed by concomitant incubation with the FXR agonist. CONCLUSIONS: Through the inhibition of renal 8-iso-PGF2α production and the down-regulation of the COX-TXA2 pathway, our study suggests that chronic OCA treatment can ameliorate the HRS in ascitic cirrhotic rats. Thus, OCA is an agent with antioxidative stress, antivasoconstrictive, antiapoptotic properties which benefit ascitic, cirrhotic rats with systemic, hepatic, and renal abnormalities.

Antiviral effect of saikosaponin B2 in combination with daclatasvir on NS5A resistance-associated substitutions of hepatitis C virus.

BACKGROUND: Hepatitis C virus (HCV) is a major causative agent of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. The rapid progress in the development of direct-acting antivirals has greatly elevated the cure rate to ≥95% in recent years. However, the high cost of treatment is not affordable to patients in some countries, necessitating the development of less expensive treatment. METHODS: We adopted a cell culture-derived HCV system to screen a library of the pure compounds extracted from herbs deposited in the chemical bank of the National Research Institute of Chinese Medicine, Taiwan. RESULTS: We found that saikosaponin B2 inhibited viral entry, replication, and translation. Saikosaponin B2 is a plant glycoside and a component of xiao-chai-hu-tang, a traditional Chinese herbal medicine extracted from the roots of Bupleurum falcatum. It also inhibited daclatasvir-resistant mutant strains of HCV, especially in combination with daclatasvir. CONCLUSION: Our results may aid the development of a new combination therapy useful for patients with HCV who are intolerant or refractory to the currently available medications, including pegylated interferon and direct-acting antiviral agents.

Inhibitory Effects of Amentoflavone and Orobol on Daclatasvir-Induced Resistance-Associated Variants of Hepatitis C Virus.

Hepatitis C virus (HCV) is recognized as a major causative agent of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Despite rapid progress in the development of direct-acting antivirals (DAA) against HCV infection in recent years, cost-effective antiviral drugs with more affordable prices still need to be developed. In this study, we screened a library of natural compounds to identify natural HCV inhibitors. The library of the pure compounds extracted from Chinese herbs deposited in the chemical bank of National Research Institute of Chinese Medicine (NRICM), Taiwan was screened in the cell culture-derived HCV (HCVcc) system. We identified the flavone or flavan-based compounds amentoflavone, 7,4[Formula: see text]-dihydroxyflavanone, and orobol with the inhibition of viral entry, replication, and translation of the HCV life cycle. Amentoflavone and orobol also showed inhibitory effects on resistant-associated variants to the NS5A inhibitor daclatasvir. The results of this study have the potential to benefit patients who are intolerant to the adverse effect of pegylated interferon or who harbor resistant strains refractory to treatment by current direct-acting antiviral agents.

Chronic calcitriol supplementation improves the inflammatory profiles of circulating monocytes and the associated intestinal/adipose tissue alteration in a diet-induced steatohepatitis rat model.

Vitamin D deficiency and up-regulated TNFα-related signals are reported to be involved in abnormalities including intestinal hyper-permeability, bacterial translocation, systemic/portal endotoxemia, intestinal/adipose tissue/hepatic inflammation, and hepatic steatosis in nonalcoholic steatohepatitis (NASH). This study aims to explore the molecular mechanisms and effects of chronic calcitriol [1,25-(OH)2D3, hormonal form of vitamin D] on gut-adipose tissue-liver axis abnormalities using a high-fat diet (HFD)-fed rat model of NASH. In HFD-fed obese rats on a 10-week calcitriol (0.3 µg/kg/TIW) or vehicle treatment (NASH-vit. D and NASH-V rats) reigme, various in vivo and in vitro experiments were undertaken. Through anti-TNFα-TNFR1-NFκB signaling effects, chronic calcitriol treatment significantly restored plasma calcitriol levels and significantly improved vitamin D receptor (VDR) expression in monocytes and the small intestine of NASH-vit. D rats. Significantly, plasma and portal endotoxin/TNFα levels, bacterial translocation to mesenteric lymph nodes, plasma DX-4000-FITC, fecal albumin-assessed intestinal hyper-permeability, over-expression of TNFα-related immune profiles in monocytes, inflammation of intestinal/mesenteric adipose tissue (MAT)/liver and hepatic steatosis were improved by chronic calcitriol treatment of NASH rats. Additionally, in vitro experiments with acute calcitriol co-incubation reversed NASH-V rat monocyte supernatant/TNFα-induced monolayer barrier dysfunction in caco-2 cells, cytokine release from MAT-derived adipocytes, and triglyceride synthesis by lean-V rat hepatocytes. Using in vivo and in vitro experiments, our study reported calcitriol signaling in the gut as well as in adipose tissue. Meanwhile, our study suggests that restoration of systemic and intestinal vitamin D deficiency using by chronic vitamin D treatment effectively reduces TNFα-mediated immunological abnormalities associated with the gut-adipose tissue-liver axis and hepatic steatosis in NASH rats.

Outcomes of sequential treatment with sorafenib followed by regorafenib for HCC: Additional analyses from the phase III RESORCE trial.

BACKGROUND & AIMS: The RESORCE trial showed that regorafenib improves overall survival (OS) in patients with hepatocellular carcinoma progressing during sorafenib treatment (hazard ratio [HR] 0.62, 95% confidence interval [CI] 0.50-0.78; p <0.0001). This exploratory analysis describes outcomes of sequential treatment with sorafenib followed by regorafenib. METHODS: In RESORCE, 573 patients were randomized 2:1 to regorafenib 160 mg/day or placebo for 3 weeks on/1 week off. Efficacy and safety were evaluated by last sorafenib dose. The time from the start of sorafenib to death was assessed. Time to progression (TTP) in RESORCE was analyzed by TTP during prior sorafenib treatment. RESULTS: HRs (regorafenib/placebo) for OS by last sorafenib dose were similar (0.67 for 800 mg/day; 0.68 for <800 mg/day). Rates of grade 3, 4, and 5 adverse events with regorafenib by last sorafenib dose (800 mg/day vs. <800 mg/day) were 52%, 11%, and 15% vs. 60%, 10%, and 12%, respectively. Median times (95% CI) from the start of sorafenib to death were 26.0 months (22.6-28.1) for regorafenib and 19.2 months (16.3-22.8) for placebo. Median time from the start of sorafenib to progression on sorafenib was 7.2 months for the regorafenib arm and 7.1 months for the placebo arm. An analysis of TTP in RESORCE in subgroups defined by TTP during prior sorafenib in quartiles (Q) showed HRs (regorafenib/placebo; 95% CI) of 0.66 (0.45-0.96; Q1); 0.26 (0.17-0.40; Q2); 0.40 (0.27-0.60; Q3); and 0.54 (0.36-0.81; Q4). CONCLUSIONS: These exploratory analyses show that regorafenib conferred a clinical benefit regardless of the last sorafenib dose or TTP on prior sorafenib. Rates of adverse events were generally similar regardless of the last sorafenib dose. LAY SUMMARY: This analysis examined characteristics and outcomes of patients with hepatocellular carcinoma who were treated with regorafenib after they had disease progression during sorafenib treatment. Regorafenib provided clinical benefit to patients regardless of the pace of their disease progression during prior sorafenib treatment and regardless of their last sorafenib dose. The sequence of sorafenib followed by regorafenib for hepatocellular carcinoma may extend survival beyond what has been previously reported. ClinicalTrials.gov NCT01774344.

Validation of the albumin-bilirubin grade-based integrated model as a predictor for sorafenib-failed hepatocellular carcinoma.

BACKGROUND & AIMS: Sorafenib is the standard treatment for advanced hepatocellular carcinoma (HCC) but is challenging after treatment failure. Appropriate criteria for enrolling patients into second-line trials are still limited. In this study, we aimed to establish more objective criteria based on Albumin-Bilirubin (ALBI) grade to select patients with better post-progression survival (PPS) for second-line treatment. METHODS: Consecutive 404 advanced HCC patients receiving sorafenib were retrospectively enrolled. All patients were in Child-Pugh class A and BCLC stage C with either portal vein invasion or extrahepatic metastasis at the beginning of sorafenib treatment. Radiological evaluation based on mRECIST criteria and clinical assessments with compliance were performed on schedule. RESULTS: During the median follow-up period of 5.8 months, 310 patients developed progressive disease (PD) and 350 deaths occurred. The PD patients were randomized into derivation and validation cohorts by a 1:1 ratio. The independent predictors of poor PPS in derivation cohort were ALBI grade 3 at PD (hazard ratio [HR]=3.24, P = .002), new extrahepatic lesions (NEH) (HR=1.75, P = .011), and early PD within 4 months (HR=1.88, P = .037). ALBI-PD criteria were proposed by incorporating these three risk factors. In the validation cohort, PPS could be independently predicted by presence of early PD, NEH as well as ALBI grade 3 at PD. Patients within ALBI-PD criteria had significant longer median PPS than those beyond it even in Child-Pugh A (9.7 vs 4.9 months, P = .005) subpopulations. CONCLUSIONS: The ALBI-PD criteria can differentiate PPS and stratify the patients with advanced HCC for the second-line trials or salvage therapy.

Hepatocellular Carcinoma: Nomograms Based on the Albumin-Bilirubin Grade to Assess the Outcomes of Radiofrequency Ablation.

Purpose To construct a nomogram with the albumin-bilirubin (ALBI) grade to assess the long-term outcomes of patients with early-stage hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA). Materials and Methods This retrospective study was approved by the institutional review board, and informed consent was waived. We studied 622 treatment-naïve patients with HCC according to the Milan criteria who subsequently underwent RFA from 2002 to 2013. Baseline characteristics were collected to identify the risk factors for determination of poor overall survival after RFA. The multivariate Cox proportional hazards model based on significant prognostic factors of overall survival was used to construct the nomogram. Results After a median follow-up time of 35.7 months, 190 patients had died. The cumulative 5- and 10-year overall survival rates were 63.1% and 48.7%, respectively. Stratified according to ALBI grade, the cumulative 5- and 10-year survival rates were 80.0% and 67.9% for patients with grade 1, respectively, and 48.6% and 35.1% for those with grades 2-3, respectively (P < .001). Multivariate analysis results showed that patient age older than 65 years, a prothrombin time international normalized ratio greater than 1.1, α-fetoprotein level greater than 20 ng/mL, multiple tumors, and ALBI grade 2 or 3 were associated with overall mortality. A nomogram was developed on the basis of these five variables. Internal validation with 200 bootstrapped sample sets had a good concordance index of 0.770 (95% confidence interval: 0.633, 0.876). Conclusion This simple nomogram based on the ALBI grade offers personalized long-term survival data for patients with early-stage HCC who undergo RFA. © RSNA, 2017 Online supplemental material is available for this article.

Clinical efficacy of Rong-Yang-Jyh-Gan-Tang on patients with chronic hepatitis C: A double-blinded randomized placebo-controlled crossover study.

ETHNOPHARMACOLOGICAL RELEVANCE: Traditional Chinese medicine (TCM) has been widely used by the Chinese population for treatment of chronic hepatitis. However, the efficacy of TCM for patients with chronic hepatitis has not been confirmed, mostly due to the lack of available scientific parameters such as serum viral load to evaluate treatment response. AIM OF THE STUDY: We evaluated the efficacy of Rong-Yang-Jyh-Gan-Tang (RYJGT, composed of Long-Dan-Xie-Gan-Tang, Jia-Wei-Xia-Yao-San, Dan-Shen, and Hou-Po) on patients with chronic hepatitis C. MATERIALS AND METHODS: Thirty-six patients with chronic hepatitis C who had no response to or had contraindications to interferon-ribavirin therapy were randomly allocated to receive RYJGT 15g/day or placebo for 12 weeks. After a 2-week washout period, patients were crossed over to receive placebo or RYJGT for another 12 weeks. Evaluation parameters included liver biochemistries, serum HCVRNA, side effects of RYJGT/placebo, and TCM symptoms. RESULTS: Of the patients who had 12-week RYJGT treatment, 51.7% had decreased serum HCVRNA levels, whereas only 25.8% patients had decreased levels in the placebo group (p=0.036). TCM patterns of "Damp-Heat" and "Liver Qi Depression" had significantly improved after RYJGT treatment in comparison with the placebo. Logistic analyses showed that RYJGT treatment, and pre-treatment values of TCM symptoms of "Damp-Heat" and "Liver Qi Depression", were statistically significant factors in predicting the decrease in serum HCVRNA. CONCLUSION: Chronic hepatitis C patients who received a 12-week RYJGT treatment had significantly higher HCVRNA decrease ratio, and improved TCM symptoms of "Damp-Heat" and "Liver Qi Depression", than those who received the placebo. Our results require further larger scale clinical trials.

Regorafenib for patients with hepatocellular carcinoma who progressed on sorafenib treatment (RESORCE): a randomised, double-blind, placebo-controlled, phase 3 trial.

BACKGROUND: There are no systemic treatments for patients with hepatocellular carcinoma (HCC) whose disease progresses during sorafenib treatment. We aimed to assess the efficacy and safety of regorafenib in patients with HCC who have progressed during sorafenib treatment. METHODS: In this randomised, double-blind, parallel-group, phase 3 trial done at 152 sites in 21 countries, adults with HCC who tolerated sorafenib (≥400 mg/day for ≥20 of last 28 days of treatment), progressed on sorafenib, and had Child-Pugh A liver function were enrolled. Participants were randomly assigned (2:1) by a computer-generated randomisation list and interactive voice response system and stratified by geographical region, Eastern Cooperative Oncology Group performance status, macrovascular invasion, extrahepatic disease, and α-fetoprotein level to best supportive care plus oral regorafenib 160 mg or placebo once daily during weeks 1-3 of each 4-week cycle. Investigators, patients, and the funder were masked to treatment assignment. The primary endpoint was overall survival (defined as time from randomisation to death due to any cause) and analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT01774344. FINDINGS: Between May 14, 2013, and Dec 31, 2015, 843 patients were screened, of whom 573 were enrolled and randomised (379 to regorafenib and 194 to placebo; population for efficacy analyses), and 567 initiated treatment (374 received regorafenib and 193 received placebo; population for safety analyses). Regorafenib improved overall survival with a hazard ratio of 0·63 (95% CI 0·50-0·79; one-sided p<0·0001); median survival was 10·6 months (95% CI 9·1-12·1) for regorafenib versus 7·8 months (6·3-8·8) for placebo. Adverse events were reported in all regorafenib recipients (374 [100%] of 374) and 179 (93%) of 193 placebo recipients. The most common clinically relevant grade 3 or 4 treatment-emergent events were hypertension (57 patients [15%] in the regorafenib group vs nine patients [5%] in the placebo group), hand-foot skin reaction (47 patients [13%] vs one [1%]), fatigue (34 patients [9%] vs nine patients [5%]), and diarrhoea (12 patients [3%] vs no patients). Of the 88 deaths (grade 5 adverse events) reported during the study (50 patients [13%] assigned to regorafenib and 38 [20%] assigned to placebo), seven (2%) were considered by the investigator to be related to study drug in the regorafenib group and two (1%) in the placebo group, including two patients (1%) with hepatic failure in the placebo group. INTERPRETATION: Regorafenib is the only systemic treatment shown to provide survival benefit in HCC patients progressing on sorafenib treatment. Future trials should explore combinations of regorafenib with other systemic agents and third-line treatments for patients who fail or who do not tolerate the sequence of sorafenib and regorafenib. FUNDING: Bayer.

Determinants of survival after sorafenib failure in patients with BCLC-C hepatocellular carcinoma in real-world practice.

Sorafenib may improve progression-free survival (PFS) and overall survival (OS) of advanced hepatocellular carcinoma (HCC). However, the survival benefit is short lived and survivals after progressive disease (PD) have not been well characterized. This study aimed to evaluate the survival predictors of OS and postprogression survival (PPS) in advanced HCC patients receiving sorafenib treatment. Consecutive 149 HCC patients receiving sorafenib under National Health Insurance were retrospectively enrolled. All patients fulfilled the reimbursement criteria: Barcelona Clinic Liver Cancer stage C HCC with macroscopic vascular invasion or extrahepatic metastasis (Mets), and Child-Pugh class A. Radiologic assessment was performed at a 2-month interval using modified Response Evaluation Criteria in Solid Tumors. Patients who maintained Eastern Cooperative Oncology Group ≤2 and Child-Pugh class A at PD were assumed to be candidates for second-line treatment. During the median follow-up period of 7.5 months (range, 1.1-18.5), PD developed in 120 (80.5%) patients and 96 (64.4%) deaths occurred. The median PFS, OS, and PPS were 2.5, 8.0, and 4.6 months, respectively. In general, patients with Mets only had better OS and PPS than those with portal vein invasion. Independent predictors of OS include baseline performance status (hazard ratio [HR] = 1.956), tumor size (HR = 1.597), alpha-fetoprotein (HR = 1.869), discontinuation of sorafenib due to liver function deterioration (LD) (HR = 6.142), or concurrent PD and LD (HR = 2.661) and PD within 4 months (HR = 5.164). Independent predictors of PPS include deteriorated performance status (HR = 7.680), deteriorated liver functions (HR = 5.603), bilirubin (HR = 2.114), early PD (HR = 6.109), and new extrahepatic lesion (HR = 1.804). In 46 candidates for second-line trials, development of new extrahepatic lesion independently predicts poorer PPS (HR = 3.669). In conclusion performance status, liver functions, early disease progression, and progression pattern are important determinants of survival after sorafenib failure. These factors should be considered in clinical practice and second-line trial designs for patients with sorafenib failure.

Surgical resection is better than transarterial chemoembolization for hepatocellular carcinoma beyond Milan criteria independent of performance status.

BACKGROUND AND AIMS: Performance status is tightly linked with survival in patients with hepatocellular carcinoma (HCC). We investigated the impact of performance status on HCC patients beyond the Milan criteria receiving surgical resection (SR) or transarterial chemoembolization (TACE). METHODS: A total of 909 patients with HCC beyond the Milan criteria were retrospectively analyzed by using propensity score analysis. RESULTS: The baseline characteristics were similar between the SR and TACE group for patients with performance status 0 in the propensity model. More patients in the TACE group with performance status ≥1 had Child-Turcotte-Pugh class A compared to the SR group (p = 0.044) in the propensity model. SR provided significantly better long-term overall survival than TACE in patients selected in the propensity model regardless of performance status (both p < 0.05). In the Cox proportional hazards model, TACE was associated with 2.279-fold and 3.066-fold increased risk of mortality in performance status 0 and performance status ≥1 in the propensity model (95% confidence interval, 1.476-3.591 and 1.570-5.989), respectively. CONCLUSIONS: For either performance status 0 or ≥1 HCC patients beyond the Milan criteria, SR provides significantly better long-term survival than TACE. SR should be considered a priority treatment in these patients independent of performance status.

Regulation by resveratrol of the cellular factors mediating liver damage and regeneration after acute toxic liver injury.

BACKGROUND AND AIM: Acute liver injury is manifested by different degree of hepatocyte necrosis and may recover via the process of hepatocyte regeneration once the injury is discontinued. Most of the liver injury is associating with inflammatory cytokines. Resveratrol (RSV) is a natural phytoalexin with powerful anti-inflammatory effects. AIM: The effects of RSV on cellular factors mediating liver damage and regeneration in acute carbon tetrachloride (CCl4 ) liver injury were investigated. RESULTS: RSV decreased alanine aminotransferase, aspartate aminotransferase, necrosis, and 4-hydroxynonenal in the CCl4 -injured liver. RSV decreased hepatocyte apoptosis by reducing caspase 8 and caspase 3 but not Bax and Bcl-xL. RSV reduced Kupffer cells recruitment, the expressions of tumor necrosis factor-α and interleukin-6, but not interleukin-10. RSV lowered the numbers of anti-5-bromon-2'-deoxyuridine and anti-Ki67-positive hepatocytes. Hepatic hepatocyte growth factor, c-Met and transforming growth factor-α expressions were reduced by RSV, while transforming growth factor-ß1 and hepatic stellate cells activation were not changed. RSV reduced the injury-induced CXCL10 elevations in serum and liver in vivo. Besides, RSV inhibited CXCL10 release from CCl4 -injured hepatocytes in vitro. In contrast, recombinant CXCL10 improved the viability of CCl4 -injured hepatocytes. CONCLUSIONS: RSV therapy can be beneficial for acute toxic liver injury. RSV reduced hepatocyte apoptosis but limited hepatocyte regeneration possibly through reducing the hepatomitogenic signaling and the release of CXCL10.

Self-administered acupressure reduces the symptoms that limit daily activities in bronchiectasis patients: pilot study findings.

AIMS AND OBJECTIVES: To examine and compare the effects of acupressure on the perceived health-related quality of life of the participants with bronchiectasis. BACKGROUND: In an attempt to offer comfort, pain control and symptom management, nursing is becoming increasingly involved in offering complementary-alternative medicine as part of its caring-healing focus in comprehensive patient care. Acupressure is one such modality that is being increasingly used by both medical and nursing professionals. While acupressure has been reported to have beneficial effects in patients with respiratory disease, the benefits to bronchiectasis patients have remained uncertain. DESIGN: A randomized, partially blinded study consisting of three groups. METHODS: Thirty-five out-patients of both genders, aged 59.46 SD 11.52 years, who were suffering from bronchiectasis, were randomly split into one of three groups: standard care with supplemental acupressure for eight weeks (11 participants); standard care with supplemental sham acupressure for eight weeks (11 participants); and standard care alone (13 participants). Outcomes were determined by changes in daily sputum amounts, sputum self-assessment, six-minute walking distance, breathing difficulty (measured on the dyspnea visual analogue scale) and health-related quality of life (measured by the Saint George Respiratory Questionnaire). RESULTS: The sputum self-assessment score improved over time for the sham acupressure participants (P = 0.03), when compared with the controls. For acupressure participants, the Saint George respiratory questionnaire activity component scores also improved over time, compared with controls (P = 0.01) after adjustment for covariates (treatment, time, age, sex and baseline values). Other variables did not differ between the standard care alone group and the other two groups. CONCLUSIONS: Eight weeks of self-administered acupressure could be useful in reducing the effects of bronchiectasis on a patient's daily activities. RELEVANCE TO CLINICAL PRACTICE: Acupressure may be regarded as a viable nursing intervention.
