Abstract
Background A wide range of ablative and non-surgical therapies are available for treating small hepatocellular carcinoma in patients with very early or early-stage disease and preserved liver function. Objective To review and compare the effectiveness of all current ablative and non-surgical therapies for patients with small hepatocellular carcinoma (≤ 3 cm). Design Systematic review and network meta-analysis. Data sources Nine databases (March 2021), two trial registries (April 2021) and reference lists of relevant systematic reviews. Review methods Eligible studies were randomised controlled trials of ablative and non-surgical therapies, versus any comparator, for small hepatocellular carcinoma. Randomised controlled trials were quality assessed using the Cochrane Risk of Bias 2 tool and mapped. The comparative effectiveness of therapies was assessed using network meta-analysis. A threshold analysis was used to identify which comparisons were sensitive to potential changes in the evidence. Where comparisons based on randomised controlled trial evidence were not robust or no randomised controlled trials were identified, a targeted systematic review of non-randomised, prospective comparative studies provided additional data for repeat network meta-analysis and threshold analysis. The feasibility of undertaking economic modelling was explored. A workshop with patients and clinicians was held to discuss the findings and identify key priorities for future research. Results Thirty-seven randomised controlled trials (with over 3700 relevant patients) were included in the review. The majority were conducted in China or Japan and most had a high risk of bias or some risk of bias concerns. The results of the network meta-analysis were uncertain for most comparisons. There was evidence that percutaneous ethanol injection is inferior to radiofrequency ablation for overall survival (hazard ratio 1.45, 95% credible interval 1.16 to 1.82), progression-free survival (hazard ratio 1.36, 95% credible interval 1.11 to 1.67), overall recurrence (relative risk 1.19, 95% credible interval 1.02 to 1.39) and local recurrence (relative risk 1.80, 95% credible interval 1.19 to 2.71). Percutaneous acid injection was also inferior to radiofrequency ablation for progression-free survival (hazard ratio 1.63, 95% credible interval 1.05 to 2.51). Threshold analysis showed that further evidence could plausibly change the result for some comparisons. Fourteen eligible non-randomised studies were identified (n ≥ 2316); twelve had a high risk of bias so were not included in updated network meta-analyses. Additional non-randomised data, made available by a clinical advisor, were also included (n = 303). There remained a high level of uncertainty in treatment rankings after the network meta-analyses were updated. However, the updated analyses suggested that microwave ablation and resection are superior to percutaneous ethanol injection and percutaneous acid injection for some outcomes. Further research on stereotactic ablative radiotherapy was recommended at the workshop, although it is only appropriate for certain patient subgroups, limiting opportunities for adequately powered trials. Limitations Many studies were small and of poor quality. No comparative studies were found for some therapies. Conclusions The existing evidence base has limitations; the uptake of specific ablative therapies in the United Kingdom appears to be based more on technological advancements and ease of use than strong evidence of clinical effectiveness. However, there is evidence that percutaneous ethanol injection and percutaneous acid injection are inferior to radiofrequency ablation, microwave ablation and resection.

Abstract
BACKGROUND & AIMS Non-surgical therapies are frequently used for patients with early or very early hepatocellular carcinoma (HCC). The aim of this systematic review and network meta-analysis (NMA) was to evaluate and compare the effectiveness of ablative and non-surgical therapies for patients with small HCC. METHODS Nine databases were searched (March 2021) along with clinical trial registries. Randomised controlled trials (RCTs) of any ablative or non-surgical therapy versus any comparator in patients with HCC ≤3 cm were eligible. Risk of bias (RoB) was assessed using the Cochrane RoB 2 tool. The effectiveness of therapies was compared using NMA. Threshold analysis was undertaken to identify which NMA results had less robust evidence. RESULTS Thirty-seven eligible RCTs were included (including over 3700 patients). Most were from China (n = 17) or Japan (n = 7). Sample sizes ranged from 30 to 308 patients. The majority had a high RoB or some RoB concerns. No RCTs were identified for some therapies and no RCTs reported quality of life outcomes. The results of the NMA and treatment effectiveness rankings were very uncertain. However, the evidence demonstrated that percutaneous ethanol injection was worse than radiofrequency ablation for overall survival (hazard ratio [HR]: 1.45, 95% credible interval [CrI]: 1.16-1.82), progression-free survival (HR: 1.36, 95% CrI: 1.11-1.67), overall recurrence (relative risk [RR]: 1.19, 95% CrI: 1.02-1.39) and local recurrence (RR: 1.80, 95% CrI: 1.19-2.71). The threshold analysis suggested that robust evidence was lacking for some comparisons. CONCLUSIONS It is unclear which treatment is most effective for patients with small HCC because of limitations in the evidence base. It is also not known how these treatments would impact on quality of life. Further high quality RCTs are needed to provide robust evidence but may be difficult to undertake.

Abstract
BACKGROUND Several treatments are available for treatment of early and very early-stage Hepatocellular Carcinoma, also known as small Hepatocellular Carcinoma (SHCC). However, there is no consensus with regards to the efficacies of these methods. We aimed at identifying the most effective initial treatment strategy for SHCC through Bayesian network meta-analyses. METHODS Studies published between January, 2010, and February, 2021 were searched in EMBASE, Cochrane Library, PubMed and Web of science databases, and conference proceedings for trials. The included studies reported the survival outcomes of very early and early Hepatocellular Carcinoma patients subjected to radiofrequency ablation (RFA), microwave ablation (MWA), surgical resection (SR), transarterial chemoembolization (TACE), percutaneous ethanol injection (PEI), minimally invasive liver surgery (MIS), stereotactic body radiotherapy (SBRT) and cryoablation (CA). Then, data were extracted from studies that met the inclusion criteria. Patient survival data were retrieved from the published Kaplan-Meier curves and pooled. A Bayesian random-effects model was used to combine direct and indirect evidence. RESULTS A total of 2058 articles were retrieved and screened, from which 45 studies assessing the efficacies of 8 different treatments in 11,364 patients were selected. The included studies had high methodological quality. Recurrence free survival* (progression/recurrence/relapse/disease/tumor-free survival were combined and redefined as RFS*) and overall survival (OS) outcomes were highest in MIS-treated patients (HR 0·57, 95% confidence intervals [CI] 0·38-0·85; HR 0.48,95% CI 0.36-0.64, respectively), followed by SR-treated patients (HR 0.60, 95% CI 0.50-0.74; HR 0.62, 95% CI 0.55-0.72, respectively). TACE was highly efficacious (58.9%) at decreasing the rates of major complications. Similar findings were obtained through sensitivity analysis, and in most of the prognostic subgroups. CONCLUSIONS MIS and SR exhibited the highest clinical efficacies, however, they were associated with higher rates of complications. Ablation is effective in small tumors, whereas SBRT is a relatively promising treatment option for SHCC. More well-designed, large-scale randomized controlled trials should be performed to validate our findings.

Hyperthermia ablation combined with transarterial chemoembolization versus monotherapy for hepatocellular carcinoma: A systematic review and meta-analysis. Cancer Med 2021; 10:8432-8450. [PMID: 34655179 PMCID: PMC8633247 DOI: 10.1002/cam4.4350] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Revised: 09/15/2021] [Accepted: 10/03/2021] [Indexed: 12/16/2022] Open
Abstract
BACKGROUND AND AIMS The existing evidence has indicated that hyperthermia ablation (HA) and HA combined with transarterial chemoembolization (HATACE) are the optimal alternative to surgical resection for patients with hepatocellular carcinoma (HCC) in the COVID-19 crisis. However, the evidence for decision-making is lacking in terms of comparison between HA and HATACE. Herein, a comprehensive evaluation was performed to compare the efficacy and safety of HATACE with monotherapy. MATERIALS AND METHODS Worldwide studies were collected to evaluate the HATACE regimen for HCC due to the practical need for global extrapolation of applicative population. Meta-analyses were performed using the RevMan 5.3 software (The Nordic Cochrane Centre, The Cochrane Collaboration, Copenhagen, Denmark). RESULTS Thirty-six studies involving a large sample of 5036 patients were included finally. Compared with HA alone, HATACE produced the advantage of 5-year overall survival (OS) rate (OR:1.90; 95%CI:1.46,2.46; p < 0.05) without increasing toxicity (p ≥ 0.05). Compared with TACE alone, HATACE was associated with superior 5-year OS rate (OR:3.54; 95%CI:1.96,6.37; p < 0.05) and significantly reduced the incidences of severe liver damage (OR:0.32; 95%CI:0.11,0.96; p < 0.05) and ascites (OR:0.42; 95%CI:0.20,0.88; p < 0.05). Subgroup analysis results of small (≤3 cm) HCC revealed that there were no significant differences between the HATACE group and HA monotherapy group in regard to the OS rates (p ≥ 0.05). CONCLUSIONS Compared with TACE alone, HATACE was more effective and safe for HCC. Compared with HA alone, HATACE was more effective for non-small-sized (>3 cm) HCC with comparable safety. However, the survival benefit of adjuvant TACE in HATACE regimen was not found for the patients with small (≤3 cm) HCC.

Abstract
Background Transarterial chemoembolization (TACE) is indicated for unresectable hepatocellular carcinoma. Methods This was a retrospective study of 50 hepatocellular carcinoma patients treated with TACE using doxorubicin-loaded LifePearl™ to investigate the safety and efficacy of TACE. Results There was no 30-day mortality, and limited adverse events were reported. At best tumor response, complete response and disease control were 58% and 94%, respectively, with a median of 4.5 months of follow-up. Median overall survival was 33.8 months. Patients with Barcelona Clinic Liver Cancer stage 0 and stage A at best tumor response showed a higher complete response rate (83%) than patients with Barcelona Clinic Liver Cancer stage B (complete response: 50%; p = 0.0414). Conclusion Doxorubicin-loaded LifePearl™ TACE might be an effective treatment, with a good safety profile, for patients with early/intermediate-stage hepatocellular carcinoma. Further prospective data, especially with a small cohort of selected patients, are required to confirm these results.

Abstract
BACKGROUND Several treatment strategies for early stage hepatocellular cancers (HCC) have been evaluated in randomised controlled trials (RCTs). This network meta-analysis (NMA) aimed to explore the relative effectiveness of these different approaches on their impact on overall (OS) and recurrence-free survival (RFS). METHODS A systematic review was conducted to identify RCT's reported up to 23rd January 2020. Indirect comparisons of all regimens were simultaneously compared using random-effects NMA. RESULTS Twenty-eight RCT's, involving 3,618 patients, reporting 13 different treatment strategies for early stage HCC were identified. Median follow-up, reported in 22 studies, ranged from 12-93 months. In this NMA, RFA in combination with iodine-125 was ranked first for both RFS (HR: 0.50, 95% CI: 0.19-1.31) and OS (HR: 0.41, 95% CI: 0.19-0.94). In subgroup with solitary HCC, lack of studies reporting RFS precluded reliable analysis. However, RFA in combination with iodine-125 was associated with markedly better OS (HR: 0.21, 95% CI: 0.05-0.93). CONCLUSION This NMA identified RFA in combination with iodine-125 as a treatment delivering better RFS and OS, in patients with early stage HCC, especially for those with solitary HCC. This technique warrants further evaluation in both Asia and Western regions.

Abstract
OBJECTIVE To compare overall survival (OS) and local recurrence (LR) following radiofrequency ablation (RFA), microwave ablation (MWA), and cryoablation (CA) for very early and early hepatocellular carcinoma (HCC). METHODS This systematic review was performed according to the PRISMA guidelines. MEDLINE, Embase, and Cochrane databases were searched. Randomized controlled trials (RCTs) and observational studies were included. OS and LR at 1 year and 3 years were assessed. OS was reported as hazard ratio (HR) with 95% credible intervals (CrI) and LR as relative risk (RR) with 95% CrI, to summarize effect of each comparison. RESULTS Nineteen studies (3043 patients), including six RCTs and 13 observational studies, met inclusion criteria. For OS at 1 year, as compared to RFA, CA had HR of 0.81 (95% CrI: 0.43-1.51), and MWA had HR of 1.01 (95% CrI: 0.71-1.43). For OS at 3 years, as compared to RFA, CA had HR of 0.90 (95% CrI: 0.48-1.64) and MWA had HR of 1.07 (95% CrI: 0.73-1.50). For LR at 1 year, CA and MWA had RR of 0.75 (95% CrI: 0.45-1.24) and 0.93 (95% CrI: 0.78-1.14), respectively, as compared to RFA. For LR at 3 years, CA and MWA had RR of 0.96 (0.74-1.23) and 0.98 (0.87-1.09), respectively, as compared to RFA. Overall, none of the comparisons was statistically significant. Age of patients and tumor size did not influence treatment effect. CONCLUSIONS RFA, MWA, and CA are equally effective for locoregional treatment of very early and early HCC. KEY POINTS • There is no significant difference in the OS and LR (at 1 year and 3 years) following ablation of very early and early HCC with RFA, MWA, and CA. • There was no effect of tumor size on the treatment efficacy. • More RCTs comparing CA with RFA and MWA should be performed.

Abstract
Background Conventional transarterial chemoembolization (cTACE) has been the standard treatment for intermediate stage hepatocellular carcinoma (HCC). For early stage HCC, percutaneous ablation is a curative option. There is growing evidence to support combined therapy to improve tumor response and overall survival (OS) in patients with unresectable HCC. The goal of this study is to retrospectively review a single institution patient population who underwent the combined approach to determine its efficacy and safety, and possible predictive factors for OS and tumor response. Methods Retrospective analysis identified all patients that underwent c-TACE with Mitomycin followed by percutaneous ablation from 2011 to 2016 at our institution. Efficacy was assessed by OS, time to progression (TTP), and tumor response according to mRECIST criteria. Initial imaging was obtained 1 month after each treatment and after complete response was achieved, every 3 months for 2 years. Percentage of Lipiodol uptake was determined at 30-day follow-up with contrasted abdominal CT. Safety was assessed using Common Terminology Criteria for Adverse Events (CTCAE) v4.0. Multiple linear regressions were conducted to predict OS and number of progression-free survival days based on potential predictive factors. Results A total of 50 patients were identified. At 1-month follow-up, objective response (CR + PR) was achieved in 44 patients (88%). The median OS was 26.6 months and median TTP was 9.7 months (n=50). There was no statistically significant difference in median OS between patients with different lesion size (P=0.95), BCLC stage (P=0.84) or Lipiodol uptake (P=0.36). Higher albumin/bilirubin ratio was significantly correlated with improved OS (P=0.024). Conclusions Combined c-TACE and PTA is a safe and effective approach for patients with unresectable HCC. Elevated albumin/bilirubin ratio was a predictor for improved OS.

Abstract
Objective To assess the clinical efficacy and safety of transarterial embolization (TAE) in simultaneous combination with computed tomography (CT)-guided radiofrequency ablation (RFA) for recurrent or residual hepatocellular carcinoma (HCC), and to determine the risk factors influencing local tumor progression following this procedure. Methods One hundred eighteen patients with recurrent or residual HCC (tumor size, 10-30 mm) underwent RFA. During the 19-month follow-up, 59 patients received RFA only (RFA group), and the remaining 59 received RFA immediately after TAE (TAE + RFA group). All patients were followed up to observe the short-term therapeutic effects and complications. The cumulative local tumor progression rates in both groups were calculated using unpaired Student's t tests and the Kaplan-Meier method. Results The rate of major complications was 5.08% in the TAE + RFA group and 3.39% in the RFA group. The overall response rate was 96.61% in the TAE + RFA group and 79.66% in the RFA group (P = 0.008). The disease control rate was significantly higher in the TAE + RFA group than in the RFA group (94.92% vs. 79.66%, P = 0.024). The median time to local tumor progression was 4.8 months in the RFA group and 9.6 months in the TAE + RFA group. The cumulative local tumor progression rate at 1 year was 10.60% in the RFA group and 23.60% in the TAE + RFA group (P = 0.016). Conclusion TAE in simultaneous combination with CT-guided RFA was effective and safe against recurrent or residual HCC. Local tumor progression can be minimized by the complete ablation of targeted iodized oil deposits after simultaneous TAE.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related death in the world. Paris polyphylla, also known as Chong-lou in China, is traditionally used as an anticancer medicine. Paris saponin H (Ps H) has been reported to be one potential antitumor active component from Paris polyphylla and shows cytotoxicity on tumor cells. However, the role of Ps H in HCC is not clear. METHODS PLC/PRF/5 and Huh7 cells were exposed to Ps H. Cell viability, migration, and invasion were measured with CCK-8 assay, EMT and Transwell assay, respectively. Western blot was employed to detect the expression of cleaved caspase 3, E-cadherin, vimentin, β-catenin, p-GSK-3β and GSK-3β. Apoptosis was assessed by flow cytometry, and caspase 3 activity assay. For in vivo experiments, xenograft tumors were induced with PLC/PRF/5 cells. RESULTS Ps H reduced cell viability and induced apoptosis in HCC cells in the dose-dependent manner; EMT and invasion were inhibited by Ps H. Ps H downregulated expression of β-catenin and p-GSK-3β; in addition, β-catenin silencing mediated Ps H-induced suppression of cell progression in PLC/PRF/5 cells. An administration of Ps H effectively suppressed the tumor growth in the HCC xenograft model in vivo. CONCLUSION Ps H suppresses HCC cell progression through downregulation of β-catenin in vitro, and inhibits xenograft tumor growth, suggesting Ps H is an attractive candidate for clinical therapy for HCC.

Abstract
PURPOSE OF REVIEW To review the current status and ideal time interval of the combination therapy of transarterial chemoembolization (TACE) and local ablation for patients with HCCs. RECENT FINDINGS In recent years, local ablation has been proposed as an alternative curative treatment in the management of HCC. Additionally, many treatment options are available including TACE molecular targeted agents and immune checkpoint inhibitors. Similar overall survival rates and prognoses have been obtained with radiofrequency ablation (RFA) microwave ablation (MWA) and cryoablation for patients with HCCs up to 3 cm in diameter. Yet, MWA has shown superiority in treating large HCCs while cryoablation has several advantages compared with RFA or MWA. Furthermore, the treatment strategy of TACE combined with local ablation is widely accepted by many physicians in order to further increase the survival rate and improve the prognosis of patients with HCCs. However, the time interval between the two sessions of combination therapy remains uncertain in the current guidelines. Combination therapy of TACE and local ablation has advantages on survival and prognosis in patients with HCC compared with monotherapy. Good patient selection for the right modality needs to be carried out to guarantee the most efficacious treatment for HCC patients. Further studies are needed to find the ideal time interval between TACE and local ablation for HCC patients.

Abstract
Hepatocellular carcinoma is one of the most common malignancies of the digestive system. Traditional treatment is not effective for advanced hepatocellular carcinoma. Sorafenib is the first molecule-targeted drug for hepatocellular carcinoma treatment. The emergence of molecule-targeted drugs provided a new choice for patients with advanced hepatocellular carcinoma. In recent years, thanks to the development of immunotherapy, many new molecule-targeted drugs have been found to significantly improve the prognosis of patients with hepatocellular carcinoma. Therefore, targeted drugs have become a research hotspot. This article reviews the progress in basic and clinical research of molecule-targeted drugs for hepatocellular carcinoma.

Abstract
PURPOSE This study was designed to assess the feasibility and safety of a single-step combined therapy using radiofrequency ablation and transarterial chemoembolization (RFA + TACE) in patients with hepatocellular carcinoma (HCC) and uncontrolled coagulopathy. The study also aimed to compare the effectiveness of this approach with TACE alone, performed in a control group. MATERIAL AND METHODS One hundred and forty-three consecutive cirrhotic patients having a single HCC < 8 cm were enrolled in this observational prospective single-center study from January 2010 to June 2017 and were divided, according to coagulation tests, into three groups (A: low risk; B: intermediate risk and C: high risk of bleeding). The feasibility and safety of a single-step combined treatment (RFA followed by TACE) were evaluated in terms of technical success rate, periprocedural complications, and laboratory values variations. Tumor response obtained at 1-month CT follow-up for group C was compared with that of control group, composed by 16 matched patients with severe coagulopathy and single HCC < 8 cm, who underwent only TACE in a previous period, performed by the same operator. RESULTS Technical success was achieved in all patients, without any major complications. Minor complications rate was significantly higher in group C after RFA; however, the patients were successfully treated with subsequent TACE therapy, without any differences between pre- and post-procedural laboratory values. One-month complete response rates were similar in all the three groups; however, the response rates of group C were significantly higher as compared to that of the control TACE Group (p < .001). CONCLUSION The single-step RFA plus TACE therapy allows expansion of the indication for percutaneous thermal ablation, allowing to also include cases previously contraindicated due to the procedural high-risk of complications associated with bleeding, thus improving short-term patient outcome.

Abstract
Optimal treatment for small hepatocellular carcinoma (HCC) ≤ 3 cm remains controversial. Ablation and chemoembolization are considered for nonoperative candidates. This study compares survival among patients with solitary HCC ≤ 3 cm treated with radiofrequency ablation (RFA) and transarterial chemoembolization (TACE). Patients diagnosed with HCC ≤ 3 cm between 2005 and 2014 were included. Kaplan-Meier survival functions with log-rank tests were used to estimate recurrence-free survival and overall survival (OS) survival. Among 161 patients with solitary HCC ≤ 3 cm, 145 patients with mean age of 65.2 years (69.2) and 95 per cent prevalence of cirrhosis had operative treatment or TACE, and/or RFA. From this cohort, 27 (19%) patients had TACE, 27 (19%) patients had RFA, and 15 (10%) patients had TACE/RFA. The patients treated with definitive TACE, RFA, or TACE/RFA had a similar 1-year recurrence-free survival (23% vs 27% vs 36%, respectively, P = 0.445) and similar 5-year OS (21% vs 24% vs 33%, respectively, P = 0.287). Thirty-five (24%) patients were bridged to transplantation with TACE and/or RFA. The 5-year OS was significantly improved in patients bridged to transplantation (P < 0.001). Survival does not differ between patients with solitary HCC ≤ 3 cm treated with TACE or RFA. Patients who were bridged to transplantation had significantly greater OS compared with patients who were not transplanted.

Abstract
PURPOSE It is unclear which kind of interventional therapies is the best when treating early-stage hepatocellular carcinoma (HCC). We conducted Bayesian network meta-analyses to compare local tumor progression (LTP), total tumor recurrence and survival rates and to rank the best intervention arm. MATERIALS AND METHODS A literature search of Pubmed, Embase, Cochrane library and Clinicaltrials.gov was conducted and randomized controlled trials (RCTs) comparing the outcomes of interventional therapies on early-stage HCC were enrolled. The quality assessment was conducted using Cochrane Collaboration's tool, while the outcome synthesis of the network meta-analysis was conducted using R-3.3.4 software. RESULTS A total of 35 RCTs were enrolled for further analysis. Using network meta-analysis, it was demonstrated that radiofrequency ablation (RFA) plus adjuvant therapies achieved the best performance in decreasing the LTP rate in early-stage HCC, while hepatic resection ranked as the best arm among all the interventional techniques for LTP at 3 years. Meanwhile, hepatic resection and RFA plus adjuvant therapies were the top two best arms in decreasing total recurrence. Furthermore, RFA plus adjuvant therapeutics ranked the best in achieving overall survival outcome, followed by hepatic resection. For disease-free survival, hepatic resection was the best, while for LTP-free survival, the difference among the included treatments was not significant. CONCLUSIONS Our network meta-analysis showed that RFA-based adjuvant therapies might be the most effective interventions in achieving the best outcomes, while hepatic resection exhibited the best performance in several situations in treating early-stage HCC. More RCTs are needed to draw more solid conclusions.

Abstract
OBJECTIVE The recurrence rate in the treatment of liver tumors using radio frequency ablation (RFA) is often related to incomplete tissue necrosis and consequently the limitation in the ablation volume. This paper proposes an ablation protocol combined with the infusion of saline solution and deionized water aiming at achieving a time displacement in the roll-off occurrence and consequently increasing the volume of ablation. METHODS An infusion of saline solution and deionized water at 5 and 23 °C was performed to evaluate the influence of these liquids on the RFA procedure in ex vivo bovine liver pieces. The obtained results were used to propose a mathematical model of the roll-off phenomenon by means of the system identification techniques. RESULTS The RFA combined with the infusion of saline solution 0.9% at 5 °C presented optimal results, with a time delay of the roll-off occurrence in 27.8% compared to pure RFA ( p = 0.002) and an increase in the necrotic volume of 51.2% ( p = 0.0002). Two Box-Jenkins models were obtained to describe the roll-off phenomenon: 1) pure RFA; and 2) RFA combined with the saline solution 0.9% at 5 °C. CONCLUSION The RFA therapy combined with the saline solution 0.9% at 5 °C increases the time range to the roll-off occurrence, leading to higher necrosis volumes in ex vivo bovine liver samples. The development of a mathematical model to describe the roll-off behavior demonstrated that the transient response is improved by the infusion of the saline solution 0.9% at 5 °C.

Abstract
BACKGROUND Major treatments for small hepatocellular carcinoma (SHCC) include percutaneous ethanol injection (PEI), percutaneous acetic acid injection (PAI), radiofrequency ablation (RFA), or surgical resection (SR). We aimed to compare these therapies concerning with effectiveness and safety. METHODS Cochrane Library, PubMed, and Embase were searched for randomized controlled studies (RCTs) from inception to 30 April 2017. Odds ratios (OR) for proportion dead (PD), local recurrence (LR) and adverse events (AEs). RESULTS Fourteen RCTs were identified. Compared with SR, PEI (OR 2.79, CrI 1.25, 6.45, p < 0.01) provided a significantly increased risk of PD. Similarly, PEI (OR 4.29, CrI 1.18, 18.35, p < 0.01) yielded more LR than SR. Also, SR significantly conferred more AEs than RFA (OR 0.10; CrI 0.02, 0.35, p < 0.01), PEI (OR 0.06; CrI 0.01, 0.31, p < 0.01). Besides, RFA conferred the highest efficacy for survival, time to recurrence, and new development of HCC. CONCLUSIONS SR was superior to PEI. Although SR achieved highest cumulative ranking probabilities in clinical efficacy, it obtained a low benefit-to-risk ratio for patients. RFA was superior to the other ablative therapies. For tumor sizes > 2 cm or ≤ 2 cm in diameter, SR conferred non-significant effects compared with other therapies for SHCC.

Abstract
Drug-eluting bead transarterial chemoembolization (DEB-TACE) is a relative new endovascular treatment based on the use of microspheres to release chemotherapeutic agents within a target lesion with controlled pharmacokinetics. This aspect justifies the immediate success of DEB-TACE, that nowadays represents one of the most used treatments for unresectable hepatocellular carcinoma. However, there is no consensus about the choice of the best embolotherapy technique. In this review, we describe the available microspheres and report the results of the main comparative studies, to clarify the role of DEB-TACE in the hepatocellular carcinoma management. We underline that there is no evidence about the superiority of DEB-TACE over conventional TACE in terms of efficacy, but there may be some benefits with respect to safety especially with the improvement of new technologies.

Abstract
OBJECTIVE Regulatory factor X1 (RFX1) deletion has been reported to be correlated with poor prognosis of some types of cancer. The present study aimed to investigate the prognostic value of RFX1 in HCC, especially in small hepatocellular carcinoma. METHODS Immunohistochemical assay was used to investigate RFX1 expression in 221 HCC tissues and another validation cohort of 71 small HCC samples. We also performed in vitro experiments to investigate if RFX1 regulated invasive capacity of HCC cells and expression of epithelial-mesenchymal transition (EMT) markers. RESULTS We found that RFX1 expression was significantly lower in HCC tissues compared to the corresponding non-tumor tissues. Further survival analysis suggested that the downregulation of RFX1 correlated with poor prognosis and a high recurrence risk in HCC patients, particularly in small HCC patients. Furthermore, another validation cohort of small HCC samples confirmed that downregulation of RFX1 in HCC tissues predicted high recurrence risk and poor prognosis for early stage HCC patients. In vitro studies suggested that knocking down RFX1 facilitated HCC cell invasion, while overexpression of RFX1 reduced the invasion of HCC cells. Western blot assays also indicated that RFX1 regulated expression of some EMT markers. Knocking down RFX1 decreased E-cadherin and increased vimentin expression, while RFX1 overexpression enhanced E-cadherin and decreased vimentin expression. CONCLUSIONS Our study demonstrated that RFX1 downregulation is a new predictive marker of high recurrence risk and poor prognosis of HCC; It has potential to help guide treatment for postoperative HCC patients, especially for small HCC patients.

Abstract
BACKGROUND Hepatocellular carcinoma (primary liver cancer) is classified in many ways. The Barcelona Clinic Liver Cancer (BCLC) group staging classifies the cancer based on patient's life expectancy. People with very early- or early-stage hepatocellular carcinoma have single tumour or three tumours of maximum diameter of 3 cm or less, Child-Pugh status A to B, and performance status 0 (fully functional). Management of hepatocellular carcinoma is uncertain. OBJECTIVES To assess the comparative benefits and harms of different interventions used in the treatment of early or very early hepatocellular carcinoma through a network meta-analysis and to generate rankings of the available interventions according to their safety and efficacy. However, it was not possible to assess whether the potential effect modifiers were similar across different comparisons. Therefore, we did not perform the network meta-analysis and instead assessed the benefits and harms of different interventions versus each other or versus sham or no intervention using standard Cochrane methodology. SEARCH METHODS We searched CENTRAL, MEDLINE, Embase, Science Citation Index Expanded, and trials registers to September 2016 to identify randomised clinical trials (RCTs) on hepatocellular carcinoma. SELECTION CRITERIA We included only RCTs, irrespective of language, blinding, or publication status, in participants with very early- or early-stage hepatocellular carcinoma, irrespective of the presence of cirrhosis, portal hypertension, aetiology of hepatocellular carcinoma, size and number of the tumours, and future remnant liver volume. We excluded trials including participants who were previously liver transplanted. We considered interventions compared with each other, sham, or no intervention. DATA COLLECTION AND ANALYSIS We calculated the odds ratio, mean difference, rate ratio, or hazard ratio with 95% confidence intervals using both fixed-effect and random-effects models based on available-participant analysis with Review Manager 5. We assessed the risk of bias according to Cochrane, controlled risk of random errors with Trial Sequential Analysis using Stata, and the quality of the evidence using GRADE. MAIN RESULTS Eighteen trials met the inclusion criteria for this review. Four trials (593 participants; 574 participants included for one or more analyses) compared surgery versus radiofrequency ablation in people with early hepatocellular carcinoma, eligible to undergo surgery. Fourteen trials (2533 participants; 2494 participants included for various analyses) compared different non-surgical interventions in people with early hepatocellular carcinoma, not eligible to undergo surgery. Overall, the quality of evidence was low or very low for all outcomes for both comparisons. Surgery versus radiofrequency ablationThe majority of participants had cirrhotic livers, and the hepatocellular carcinoma was of viral aetiology. The trials did not report the participants' portal hypertension status or whether they received adjuvant antiviral treatment or adjuvant immunotherapy. The average follow-up ranged from 29 months to 42 months (3 trials).There was no evidence of a difference in all-cause mortality at maximal follow-up for surgery versus radiofrequency ablation (hazard ratio 0.80, 95% confidence interval (CI) 0.60 to 1.08; 574 participants; 4 trials; I2 = 68). Cancer-related mortality was lower in the surgery group (20/115 (17.4%)) than in the radiofrequency ablation group (43/115 (37.4%)) (odds ratio 0.35, 95% CI 0.19 to 0.65; 230 participants; 1 trial). Serious adverse events (number of participants) was higher in the surgery group (14/60 (23.3%)) than in the radiofrequency ablation group (1/60 (1.7%)) (odds ratio 17.96, 95% CI 2.28 to 141.60; 120 participants; 1 trial). The number of serious adverse events was higher in the surgery group (adjusted rate 11.3 events per 100 participants) than in the radiofrequency ablation group (3/186 (1.6 events per 100 participants)) (rate ratio 7.02, 95% CI 2.29 to 21.46; 391 participants; 2 trials; I2 = 0%). None of the trials reported health-related quality of life. One trial was funded by a party with vested interests; three trials were funded by parties without any vested. Non-surgical interventionsThe majority of participants had cirrhotic livers, and the hepatocellular carcinoma was of viral aetiology. Most trials did not report the portal hypertension status of the participants, and none of the trials reported whether the participants received adjuvant antiviral treatment or adjuvant immunotherapy. The average follow-up ranged from 6 months to 37 months (11 trials). Trial participants, who were not eligible for surgery, were treated with radiofrequency ablation, laser ablation, microwave ablation, percutaneous acetic acid injection, percutaneous alcohol injection, a combination of radiofrequency ablation with systemic chemotherapy, a combination of radiofrequency ablation with percutaneous alcohol injection, a combination of transarterial chemoembolisation with percutaneous alcohol injection, or a combination of transarterial chemoembolisation with radiofrequency ablation.The mortality at maximal follow-up was higher in the percutaneous acetic acid injection (hazard ratio 1.77, 95% CI 1.12 to 2.79; 125 participants; 1 trial) and percutaneous alcohol injection (hazard ratio 1.49, 95% CI 1.18 to 1.88; 882 participants; 5 trials; I2 = 57%) groups compared with the radiofrequency ablation group. There was no evidence of a difference in all-cause mortality at maximal follow-up for any of the other comparisons. The proportion of people with cancer-related mortality at maximal follow-up was higher in the percutaneous alcohol injection group (adjusted proportion 16.8%) compared with the radiofrequency ablation group (20/232 (8.6%)) (odds ratio 2.18, 95% CI 1.22 to 3.89; 458 participants; 3 trials; I2 = 0%). There was no evidence of a difference in any of the comparisons that reported serious adverse events (number of participants or number of events). None of the trials reported health-related quality of life. Five trials were funded by parties without any vested interest; the source of funding was not available in the remaining trials. AUTHORS' CONCLUSIONS The evidence was of low or very low quality. There was no evidence of a difference in all-cause mortality at maximal follow-up between surgery and radiofrequency ablation in people eligible for surgery. All-cause mortality at maximal follow-up was higher with percutaneous acetic acid injection and percutaneous alcohol injection than with radiofrequency ablation in people not eligible for surgery. There was no evidence of a difference in all-cause mortality at maximal follow-up for the other comparisons. High-quality RCTs designed to assess clinically important differences in all-cause mortality and health-related quality of life, and having an adequate follow-up period (approximately five years) are needed.

Abstract
Hepatocellular carcinoma (HCC) is the second most common cause of cancer-related deaths worldwide with rapidly growing incidence rates in the USA and Europe. Despite improving surveillance programs, most patients are diagnosed at intermediate to advanced stages and are no longer amenable to curative therapies, such as ablation, surgical resection and liver transplantation. For such patients, catheter-based image-guided embolotherapies such as transarterial chemoembolization (TACE) represent the standard of care and mainstay therapy, as recommended and endorsed by a variety of national guidelines and staging systems. The main benefit of these therapies is explained by the preferentially arterial blood supply of liver tumors, which allows to deliver the anticancer therapy directly to the tumor-feeding artery while sparing the healthy hepatic tissue mainly supplied by the portal vein. The tool box of an interventional oncologist contains several different variants of transarterial treatment modalities. Ever since the first TACE more than 30 years ago, these techniques have been progressively refined, both with respect to drug delivery materials and with respect to angiographic micro-catheter and image-guidance technology, thus substantially improving therapeutic outcomes of HCC. This review will summarize the fundamental principles, technical and clinical data on the application of different embolotherapies, such as bland transarterial embolization, Lipiodol-based conventional transarterial chemoembolization as well as TACE with drug-eluting beads (DEB-TACE). Clinical data on 90Yttrium radioembolization as an emerging alternative, mostly applied for niche indications such as HCC with portal vein invasion, will be discussed. Furthermore, we will summarize the principle of HCC staging, patient allocation and response assessment in the setting of HCC embolotherapy. In addition, we will evaluate the role of cone-beam computed tomography as a novel intra-procedural image-guidance technology. Finally, this review will touch on new technical developments such as radiopaque, imageable DEBs and the rationale and role of combined systemic and locoregional therapies, mostly in combination with Sorafenib.

Abstract
BACKGROUND The optimal transcatheter embolization strategy for patients with unresectable hepatocellular carcinoma (HCC) remains elusive. We conducted a systematic review and network meta-analysis (NMA) of different embolization options for unresectable HCC. METHODS Medical databases were searched for randomized controlled trials evaluating bland transarterial embolization (TAE), conventional TACE, drug-eluting bead chemoembolization (DEB-TACE), or transarterial radioembolization (TARE), either alone or combined with adjuvant chemotherapy, or local liver ablation, or external radiotherapy for unresectable HCC up to June 2017. Random effects Bayesian models with a binomial and normal likelihood were fitted (WinBUGS). Primary endpoint was patient survival expressed as hazard ratios (HR) and 95% credible intervals. An exponential model was used to fit patient survival curves. Safety and objective response were calculated as odds ratios (OR) and accompanying 95% credible intervals. Competing treatments were ranked with the SUCRA statistic. Heterogeneity-adjusted effective sample sizes were calculated to evaluate information size for each comparison. Quality of evidence (QoE) was assessed with the GRADE system adapted for NMA reports. All analyses complied with the ISPOR-AMCP-NCP Task Force Report for good practice in NMA. FINDINGS The network of evidence included 55 RCTs (12 direct comparisons) with 5,763 patients with preserved liver function and unresectable HCC (intermediate to advanced stage). All embolization strategies achieved a significant survival gain over control treatment (HR range, 0.42-0.76; very low-to-moderate QoE). However, TACE, DEB-TACE, TARE and adjuvant systemic agents did not confer any survival benefit over bland TAE alone (moderate QoE, except low in case of TARE). There was moderate QoE that TACE combined with external radiation or liver ablation achieved the best patient survival (SUCRA 86% and 96%, respectively). Estimated median survival was 13.9 months in control, 18.1 months in TACE, 20.6 months with DEB-TACE, 20.8 months with bland TAE, 30.1 months in TACE plus external radiotherapy, and 33.3 months in TACE plus liver ablation. TARE was the safest treatment (SUCRA 77%), however, all examined therapies were associated with a significantly higher risk of toxicity over control (OR range, 6.35 to 68.5). TACE, DEB-TACE, TARE and adjuvant systemic agents did not improve objective response over bland embolization alone (OR range, 0.85 to 1.65). There was clinical diversity among included randomized controlled trials, but statistical heterogeneity was low. CONCLUSIONS Chemo- and radio-embolization for unresectable hepatocellular carcinoma may improve tumour objective response and patient survival, but are not more effective than bland particle embolization. Chemoembolization combined with external radiotherapy or local liver ablation may significantly improve tumour response and patient survival rates over embolization monotherapies. Quality of evidence remains mostly low to moderate because of clinical diversity. SYSTEMATIC REVIEW REGISTRATION CRD42016035796 (http://www.crd.york.ac.uk/PROSPERO).

[DOI: 10.13105/wjma.v4.i4.77] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/25/2016] [Revised: 06/28/2016] [Accepted: 07/18/2016] [Indexed: 02/05/2023] Open
Abstract
AIM To compare different antibiotics for eradicating the carriage of Neisseria meningitidis (N. meningitidis), and to investigate heterogeneity and evidence inconsistency.
METHODS From a search of PubMed and published systematic reviews, we identified 23 trials evaluating 15 antibiotics that could be connected in a trial network. The outcome of interest is the eradication of N. meningitidis. We used WinBUGS to conduct random-effects, mixed treatment comparisons. Heterogeneity and evidence inconsistency was investigated by meta-regression modelling and examining characteristics of trial participants and interventions evaluated.
RESULTS Rifampin, ciprofloxacin, minocycline, ceftriaxone, and azythromycin were statistically significantly (P < 0.05) more effective than placebo. The probability of being the best was 67.0% for a combination of rifampin and minocycline, 25.0% for ceftriaxone, 1.7% for azythromycin, and below 1% for the remaining regimens. Significant inconsistency between the direct and indirect estimates was observed for the comparison of rifampin and ciprofloxacin (P < 0.01), which may be caused by different types of carriers and different doses of ciprofloxacin.
CONCLUSION A range of prophylactic antibiotic regimens are effective for eradicating meningococcal carriages, and treatment choice will depend on the individual priorities of the patients and physicians. In clinical situations where complete eradication is considered to be of the utmost importance, a combination of rifampin and minocycline seems to offer the highest likelihood of success. Ceftriaxone as a single intramuscular injection is also likely to be more effective as compared with the other two antibiotics (ciprofloxacin or rifampin) recommended by the current guidelines.
