Abstract
Purpose To predict the efficacy of patients treated with hepatectomy and transarterial chemoembolization (TACE) based on machine learning models using clinical and radiomics features. Patients and Methods Patients with HCC whose first treatment was hepatectomy or TACE from June 2016 to July 2021 were collected in the retrospective cohort study. To ensure a causal effect of treatment effect and treatment modality, perfectly matched patients were obtained according to the principle of propensity score matching and used as an independent test cohort. Inverse probability of treatment weighting was used to control bias for unmatched patients, and the weighted results were used as the training cohort. Clinical characteristics were selected by univariate and multivariate analysis of cox proportional hazards regression, and radiomics features were selected using correlation analysis and random survival forest. The machine learning models (Deathhepatectomy and DeathTACE) were constructed to predict the probability of patient death after treatment (hepatectomy and TACE) by combining clinical and radiomics features, and an optimal treatment regimen was recommended. In addition, a prognostic model was constructed to predict the survival time of all patients. Results A total of 418 patients with HCC who received either hepatectomy (n=267, mean age, 58 years ± 11 [standard deviation]; 228 men) or TACE (n=151, mean age, 59 years ± 13 [standard deviation]; 127 men) were recruited. After constructing the machine learning models Deathhepatectomy and DeathTACE, patients were divided into the hepatectomy-preferred and TACE-preferred groups. In the hepatectomy-preferred group, hepatectomy had a significantly prolonged survival time than TACE (training cohort: P < 0.001; testing cohort: P < 0.001), and vise versa for the TACE-preferred group. In addition, the prognostic model yielded high predictive capability for overall survival. Conclusion The machine learning models could predict the outcomes difference between hepatectomy and TACE, and prognostic models could predict the overall survival for HCC patients.

Abstract
This review explores the evolution of cancer staging, focusing on intermediate hepatocellular carcinoma (HCC), and the challenges faced by physicians. The Barcelona Clinic Liver Cancer (BCLC) staging system, introduced in 1999, was designed to address the limitations associated with providing accurate prognostic information for HCC and allocating specific treatments, to avoid overtreatment. However, criticism has emerged, particularly regarding the intermediate stage of HCC (BCLC-B) and its heterogeneous patient population. To overcome this limitation, various subclassification systems, such as the Bolondi and Kinki criteria, have been proposed. These systems are aimed at refining categorizations within the intermediate stage and have demonstrated varying degrees of success in predicting outcomes through external validation. This study discusses the shift in treatment paradigms, emphasizing the need for a more personalized approach rather than strictly adhering to cancer stages, without dismissing the relevance of staging systems. It assesses the available treatment options for intermediate-stage HCC, highlighting the importance of considering surgical and nonsurgical options alongside transarterial chemoembolization for optimal outcomes. In conclusion, the text advocates for a paradigm shift in staging systems prioritizing treatment suitability over cancer stage. This reflects the evolving landscape of HCC management, where a multidisciplinary approach is crucial for tailoring treatments to individual patients, ultimately aiming to improve overall survival.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) accounts for the sixth most common cancer and ranks third in mortality worldwide with inhomogeneity in terms of resection for advanced-stage disease. METHODS A systematic review of published literature using the PubMed, Medline, and Google Scholar databases from 1995 to 2020 was conducted to identify studies that reported outcomes of resection for solitary HCC > 10 cm, BCLC B/C, and multinodular HCC. Our aim was to assess overall survival for resection, identify poor prognostic factors, and to compare it to trans-arterial chemotherapy (TACE) where data was available. RESULTS Eighty-nine articles were included after a complete database search in the systematic review as per our predefined criteria. Analysis revealed a 5-year overall survival of 33.5% for resection of HCC > 10 cm, 41.7% for BCLC B, 23.3% for BCLC C, and 36.6% for multinodular HCC. Peri-operative mortality ranged from 0 to 6.9%. Studies comparing resection versus TACE for BCLC B/C had a survival of 40% versus 17%, respectively. CONCLUSION Our systematic review justifies hepatic resection wherever feasible for hepatocellular carcinomas > 10 cm, BCLC B, BCLC C, and multinodular tumors. In addition, we identified and proposed an algorithm with five poor prognostic criteria in this group of patients who may benefit from adjuvant TACE.

Selecting the Best Approach for the Treatment of Multiple Non-Metastatic Hepatocellular Carcinoma. Cancers (Basel) 2022; 14:cancers14235997.

Abstract
According to the Barcelona Clinic Liver Cancer (BCLC) staging system, the optimal strategy for patients with multiple HCC within the Milan Criteria is liver transplantation (LT). However, LT cannot be offered to all the patients due to organ shortages and long waiting lists, as well as because of the advanced disease carrying a high risk of poor outcomes. For early stages, liver resection (LR) or thermal ablation (TA) can be proposed, while trans-arterial chemoembolization (TACE) still remains the treatment of choice for intermediate stages (BCLC-B). Asian guidelines and the National Comprehensive Cancer Network suggest LR for resectable multinodular HCCs, even beyond Milan criteria. In this scenario, a growing body of evidence shows better outcomes after surgical resection when compared with TACE. Trans-arterial radioembolization (TARE) and stereotaxic body radiation therapy (SBRT) can also play an important role in this setting. Furthermore, the role of minimally invasive liver surgery (MILS) specifically for patients with multiple HCC is still not clear. This review aims to summarize current knowledge about the best therapeutical strategy for multiple HCC while focusing on the role of minimally invasive surgery and on the most attractive future perspectives.

Abstract
PURPOSE To establish a model for assessing the overall survival (OS) of the hepatocellular carcinoma (HCC) patients after hepatectomy based on the clinical and radiomics features. METHODS This study recruited a total of 267 patients with HCC, which were randomly divided into the training (N = 188) and validation (N = 79) cohorts. In the training cohort, radiomic features were selected with the intra-reader and inter-reader correlation coefficient (ICC), Spearman's correlation coefficient, and the least absolute shrinkage and selection operator (LASSO). The radiomics signatures were built by COX regression analysis and compared the predictive potential in the different phases (arterial, portal, and double-phase) and regions of interest (tumor, peritumor 3 mm, peritumor 5 mm). A clinical-radiomics model (CR model) was established by combining the radiomics signatures and clinical risk factors. The validation cohort was used to validate the proposed models. RESULTS A total of 267 patients 86 (45.74%) and 37 (46.84%) patients died in the training and validation cohorts, respectively. Among all the radiomics signatures, those based on the tumor and peritumor (5 mm) (AP-TP5-Signature) showed the best prognostic potential (training cohort 1-3 years AUC:0.774-0.837; validation cohort 1-3 years AUC:0.754-0.810). The CR model showed better discrimination, calibration, and clinical applicability as compared to the clinical model and radiomics features. In addition, the CR model could perform risk-stratification and also allowed for significant discrimination between the Kaplan-Meier curves in most of the subgroups. CONCLUSIONS The CR model could predict the OS of the HCC patients after hepatectomy.

Abstract
BACKGROUND AND AIMS Surgical resection for patients with intermediate hepatocellular carcinoma (HCC) is preferred in China, but the prognosis remains far from satisfactory. Postoperative transarterial chemoembolization (p-TACE) has been conducted prevalently to prevent recurrence, but its efficacy remains controversial. Hence, we collected the data from primary liver cancer big data (PLCBD) to investigate the clinical value of p-TACE for patients with intermediate HCC and identify the potential beneficiaries. METHODS Patients who were diagnosed with intermediate HCC between December 2012 and December 2015 were identified through the PLCBD. Disease-free survival (DFS) of patients who received p-TACE or not following radical resection was evaluated using Kaplan-Meier survival curves before and after 1:1 propensity scoring match (PSM). Subgroup analysis was conducted stratified by risk factors associated with recurrence. RESULTS A total of 325 intermediate HCC patients receiving radical resection were eligible in this study, including 123 patients in the p-TACE group and 202 in the non-TACE group. Median DFS in the p-TACE group was significantly longer than in the non-TACE group (23.3 months vs. 18.0 months, P = 0.016) in the whole cohort with no severe complicates, which was confirmed in a well-matched cohort (17.4 months vs. 23.3 months, P = 0.012). In addition, p-TACE was identified as an independent risk factors of DFS by multivariate Cox regression analysis before and after PSM (both P < 0.05). After adjusting for other prognostic variables, patients were found to significantly benefit from p-TACE in DFS if they were male, or had hepatitis, diabetes, cirrhosis, AFP ≤ 400 ng/ml, anatomic hepatectomy, no severe surgical complication, no intraoperative transfusion, tumor number = 2, differentiation grading III, capsule, or had no transfusion (all P < 0.05). CONCLUSION With the current data, we concluded that p-TACE was safe and efficient for the patients with intermediate HCC following radical resection, and male patients with hepatitis, diabetes, cirrhosis, AFP ≤ 400 ng/ml, anatomic hepatectomy, no severe surgical complication, no intraoperative transfusion, tumor number = 2, differentiation grading III, and capsule would benefit more from p-TACE.

Homoharringtonine Exerts Anti-tumor Effects in Hepatocellular Carcinoma Through Activation of the Hippo Pathway. Front Pharmacol 2021; 12:592071. [PMID: 33716735 PMCID: PMC7943857 DOI: 10.3389/fphar.2021.592071] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Accepted: 01/07/2021] [Indexed: 12/17/2022] Open
Abstract
Hepatocellular carcinoma (HCC) is the most prevalent subtype of liver cancer with a mortality rate of approximately 3–6/100,000 and is the third leading cause of cancer-related death worldwide. Although several small-molecule drugs have been developed for the treatment of HCC, the choice of an agent for patients who require systemic chemotherapy at an advanced stage is still limited. The Hippo pathway is an evolutionarily conserved tumor suppressive pathway commonly dysregulated in HCC, which makes it a promising target for anti-HCC therapies. Homoharringtonine (HHT) is an FDA-approved anti-leukemia drug with proven strong anti-tumor activity in solid tumors. In this study, we found that HHT could significantly inhibit HCC cell growth by suppressing cell proliferation and colony formation. Moreover, HHT repressed cell invasion and migration remarkably. Additionally, HHT induced cell cycle arrest at S phase and promoted apoptosis. Most importantly, we showed that HHT-induced apoptosis was a consequence of the Hippo pathway activation. Consistently, the MST1/2 inhibitor, XMU-MP-1, could restore cell viability and reverse HHT-induced cell apoptosis. Furthermore, in vivo results confirmed the tumor inhibitory effect of HHT. Taken together, our findings suggest that HHT is a potential alternative therapeutic agent for the treatment of HCC.

Abstract
Background Transarterial chemoembolization (TACE) is currently the recommended treatment for intermediate-stage hepatocellular carcinoma (HCC). Liver resection (LR) may be an effective option, although recurrences are not uncommon. TACE prior to LR has been proposed as an even better alternative. Methods Patients with intermediate-stage HCC who underwent curative resection were enrolled between January 2007 and December 2015. We compared overall survival (OS) and recurrence-free survival (RFS) for the 2 groups using the Kaplan-Meier method, and we determined independent risk factors for death and recurrence using multivariate regression analyses. Results A total of 488 patients with HCC at BCLC B (265 patients with LR, 223 patients with TACE+LR) enrolled from our center. Mean follow-up was 40.2 (range, 3.0-128.7) months. For patients receiving TACE+LR and LR, estimated 1-, 3-, and 5-year OS rates were 90.6% and 73.3%, 61.7% and 43.5%, and 52.9% and 33.8%, respectively (all P < 0.001) and estimated 1-, 2-, and 3-year RFS rates were 54.6% and 39.4%, 41.4% and 29.4%, and 36.3% and 26.3%, respectively (P < 0.001, P = 0.002, and P = 0.008, respectively). Significant independent predictors of poor OS were more than 3 (vs. 3 or fewer) tumors (HR=2.19, 95% CI 1.69-2.84), non-anatomical (vs. anatomical) hepatectomy (HR=1.29, 95% CI 1.01-1.66), microscopic vascular invasion (HR=1.46, 95% CI 1.15-.90), cirrhosis (HR=2.41, 95%CI 1.88-3.01), and intraoperative blood transfusion (HR=1.29, 95% CI 1.01-1.66). Conclusion Preoperative TACE with LR may result in better oncological outcomes than either TACE or LR alone, without a substantial increase in morbidity, and could be considered an effective combination treatment for intermediate-stage HCC.

A Five-Gene Signature for Recurrence Prediction of Hepatocellular Carcinoma Patients. BIOMED RESEARCH INTERNATIONAL 2020; 2020:4037639. [PMID: 33163533 PMCID: PMC7604585 DOI: 10.1155/2020/4037639] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/07/2020] [Revised: 06/20/2020] [Accepted: 06/25/2020] [Indexed: 01/27/2023]
Abstract
Background Hepatocellular carcinoma (HCC) is one of the most aggressive malignancies with poor prognosis. There are many selectable treatments with good prognosis in Barcelona Clinic Liver Cancer- (BCLC-) 0, A, and B HCC patients, but the most crucial factor affecting survival is the high recurrence rate after treatments. Therefore, it is of great significance to predict the recurrence of BCLC-0, BCLC-A, and BCLC-B HCC patients. Aim To develop a gene signature to enhance the prediction of recurrence among HCC patients. Materials and Methods The RNA expression data and clinical data of HCC patients were obtained from the Gene Expression Omnibus (GEO) database. Univariate Cox regression analysis and least absolute shrinkage and selection operator (LASSO) regression analysis were conducted to screen primarily prognostic biomarkers in GSE14520. Multivariate Cox regression analysis was introduced to verify the prognostic role of these genes. Ultimately, 5 genes were demonstrated to be related with the recurrence of HCC patients and a gene signature was established. GSE76427 was adopted to further verify the accuracy of gene signature. Subsequently, a nomogram based on gene signature was performed to predict recurrence. Gene functional enrichment analysis was conducted to investigate the potential biological processes and pathways. Results We identified a five-gene signature which performs a powerful predictive ability in HCC patients. In the training set of GSE14520, area under the curve (AUC) for the five-gene predictive signature of 1, 2, and 3 years were 0.813, 0.786, and 0.766. Then, the relative operating characteristic (ROC) curves of five-gene predictive signature were verified in the GSE14520 validation set, the whole GSE14520, and GSE76427, showed good performance. A nomogram comprising the five-gene signature was built so as to show a good accuracy for predicting recurrence-free survival of HCC patients. Conclusion The novel five-gene signature showed potential feasibility of recurrence prediction for early-stage HCC.

In the Barcelona Clinic Liver Cancer staging system, intermediate stage hepatocellular carcinoma (HCC) is defined as large multinodular tumors without vascular invasion or extrahepatic spread in an asymptomatic patient with good performance status. Intermediate stage HCC includes various subgroups and it is characterized by extensive heterogeneity. Current guidelines recommend transarterial chemoembolization (TACE) as the standard treatment modality for patients with intermediate stage HCC. Although TACE provides improved survival benefits compared with supportive care for patients with intermediate stage HCC, all of them are not good candidates for TACE. TACE refractoriness is another obstacle to effective treatment of patients with intermediate stage HCC. Given that many studies recently reported improved survival in patients treated with hepatic resection over TACE, we reviewed the survival outcomes of TACE and hepatic resection as a treatment strategy of intermediate stage HCC.

Transarterial Chemoembolization in Treatment-Naïve and Recurrent Hepatocellular Carcinoma: A Propensity-Matched Outcome Analysis. Dig Dis Sci 2019; 64:3660-3668. [PMID: 31187326 DOI: 10.1007/s10620-019-05701-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Accepted: 06/04/2019] [Indexed: 02/06/2023]
Abstract
OBJECTIVES Transarterial chemoembolization (TACE) improves the survival of patients with hepatocellular carcinoma (HCC); however, TACE treatment outcomes of patients with treatment-naïve HCC (TN-HCC) and those with recurrent HCC after curative resection (R-HCC) have not yet been compared. METHODS We recruited 448 patients with TN-HCC, and 275 patients with R-HCC treated with TACE as first-line anti-cancer treatment. RESULTS At first TACE, patients with TN-HCC showed a significantly lower proportion of male gender (74.9% vs. 84.3%), higher proportion of liver cirrhosis (61.9% vs. 49.3%), higher aspartate aminotransferase (median 48 vs. 31 IU/L), alanine aminotransferase (median 38 vs. 26 IU/L), alpha-fetoprotein (AFP) (median 96.6 vs. 7.7 ng/mL), and total bilirubin (mean 1.0 vs. 0.8 mg/dL) levels, longer prothrombin time (median 1.05 vs. 1.01 international normalized ratio), higher tumor number (mean 2.1 vs. 1.7), larger tumor size (median 3.1 vs. 1.6 cm), and lower proportion of Barcelona Clinic Liver Cancer stage 0-A (55.6% vs. 71.9%) than patients with R-HCC (all P < 0.05). Multivariate analysis showed that TACE for TN-HCC (vs. R-HCC) was an independent predictor of mortality (hazard ratio, 1.328; P = 0.024) with AFP level and tumor number (all P < 0.05). However, treatment outcomes between TN-HCC and R-HCC became statistically similar after propensity score-matched (PSM) analysis using liver cirrhosis, tumor size, and multiple tumors (P < 0.05). CONCLUSIONS Based on the similar TACE treatment outcomes observed with the PSM analysis, the current TACE treatment guideline for patients with TN-HCC might similarly be applied for patients with R-HCC.

Abstract
Aberrant expression of long non-coding RNAs (lncRNAs) has been observed in hepatocellular carcinoma (HCC) and confirmed to participate in the initiation and progression of HCC. In the present study, we identified a novel functional lncRNA, hedgehog-interacting protein antisense RNA 1 (HHIP-AS1). The expression levels of HHIP-AS1 were significantly decreased in HCC tissues. Downregulation of HHIP-AS1 expression correlated with larger tumor size, metastasis, and advanced TNM stage, and also predicted worse overall survival rate of HCC patients. Through performing overexpression and knockdown experiments, the biological function of HHIP-AS1 was identified to suppress HCC cell proliferation, migration and invasion, while promote apoptosis. Further investigation showed that HHIP-AS1 interacted with and positively regulated the stability of HHIP mRNA in a HuR-dependent manner. HHIP-AS1 exerted its suppressive effects through HHIP. Taken together, our findings demonstrate that HHIP-AS1 represses HCC progression by promoting HHIP expression, and indicate that the use of HHIP-AS1 may offer a promising treatment for HCC patients.

LINC00460 promotes hepatocellular carcinoma development through sponging miR-485-5p to up-regulate PAK1. Biomed Pharmacother 2019; 118:109213. [PMID: 31376654 DOI: 10.1016/j.biopha.2019.109213] [Citation(s) in RCA: 37] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2019] [Revised: 07/05/2019] [Accepted: 07/08/2019] [Indexed: 12/18/2022] Open
Abstract
LncRNAs can function as significant regulators of tumor development. However, their roles in hepatocellular carcinoma (HCC) remain poorly investigated. LINC00460 has been identified in several cancers, which can act as an oncogene. In this study, we observed that LINC00460 was significantly up-regulated in HCC cells, which implied that LINC00460 was involved in HCC development. Then, LINC00460 was silenced in Hep3B and Huh-7 cells and we found that knockdown of LINC00460 greatly inhibited HCC cell proliferation. In addition, HCC cell apoptosis was induced and meanwhile, cell cycle progression was blocked by down-regulation of LINC00460 in vitro. Furthermore, we proved that Hep3B and Huh-7 cell migration and invasion capacity was repressed by decrease of LINC00460. Recently, a growing number of studies have indicated the correlation between lncRNAs and microRNAs. Currently, we displayed that miR-485-5p was greatly decreased in HCC cells and LINC00460 could sponge miR-485-5p to regulate HCC progression. The binding association between LINC00460 and miR-485-5p was confirmed using dual-luciferase reporter assay, RNA pulled down and RIP assay in our research. Subsequently, PAK1 was predicted as a downstream target of miR-485-5p and we demonstrated that miR-485-5p suppressed PAK1 levels in vitro. Finally, in vivo experiments were conducted to validate that knockdown of LINC00460 repressed HCC development through modulating miR-485-5p to increase PAK1. Taken these together, we indicated that LINC00460 promoted HCC progression through sponging miR-485-5p and up-regulating PAK1.

Comparison of macrovascular invasion-free survival in early-intermediate hepatocellular carcinoma after different interventions: A propensity score-based analysis. J Cancer 2019; 10:4063-4071. [PMID: 31417651 PMCID: PMC6692624 DOI: 10.7150/jca.29850] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2018] [Accepted: 05/17/2019] [Indexed: 12/13/2022] Open
Abstract
Objectives: The purpose of this study was to compare macrovascular invasion (MVI)-free survival (MFS) at the three-year follow-up in patients with hepatocellular carcinoma (HCC) who underwent hepatic resection (HR), transcatheter arterial chemoembolization (TACE), or TACE combined with radiofrequency ablation (TACE-RFA). Materials and Methods: We retrospectively analyzed the medical records of 828 patients who were diagnosed with Barcelona Clinic Liver Cancer (BCLC) stage A or stage B HCC. Of these patients, 116 underwent HR, 395 underwent TACE-RFA, 239 underwent TACE, and 78 patients received conservative treatment (control group). A validation cohort of 158 patients was included. The MFS and overall survival (OS) before and after propensity score (PS) matching were evaluated using Kaplan-Meier analysis. Results: The baseline characteristics between the control and TACE groups were comparable. MFS was higher in the TACE group than in the control group at the three-year follow-up (p = 0.0091), and OS was similar in the two groups (p = 0.0549). PS matching was used to generate 68 pairs of patients in the control versus HR group and 74 pairs of patients in the control versus TACE-RFA group (1-to-1 matched). MFS was significantly higher in the HR or TACE-RFA groups than in the control group (p < 0.0001 (HR versus control) and p = 0.0001 (TACE-RFA versus control), respectively). Furthermore, for patients in the HR versus TACE-RFA versus TACE groups that were generated by PS matching, the Kaplan-Meier analysis showed that MFS and OS were higher with HR or TACE-RFA than with TACE at three years. In the study, similar results were obtained in the validation cohort. Conclusions: MFS and OS were higher with HR or TACE-RFA than with TACE for HCC patients without MVI.

Microwave Ablation in Intermediate Hepatocellular Carcinoma in Cirrhosis: An Italian Multicenter Prospective Study. J Clin Transl Hepatol 2018; 6:251-257. [PMID: 30271736 PMCID: PMC6160301 DOI: 10.14218/jcth.2018.00013] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/22/2018] [Revised: 04/04/2018] [Accepted: 04/16/2018] [Indexed: 02/07/2023] Open
Abstract
Background and Aims: To report long-term results in treatment of intermediate hepatocellular carcinoma (HCC) in cirrhotics using new high-powered microwaves (MWS) ablation alone. Methods: This multicenter study included 215 cirrhotics (age range: 67-84 years; 137 males; 149 Child A, 66 Child B) who underwent percutaneous ultrasound-guided high-powered MWS ablation instead of transarterial chemoembolization. Among the patient population, 109 had a single nodule (Ø 5.3-8 cm) [group A], 70 had 2 nodules (Ø 3-6 cm) [group B] and 36 had 3-5 nodules (Ø 1.5-6.8 cm) [group C]. MWS ablation efficacy was evaluated using enhanced-computed tomography and/or magnetic resonance imaging. Primary end-point was 5-year cumulative overall survival (OS). Results: On enhanced-computed tomography and/or magnetic resonance imaging, complete ablation rates were 100% for 1.5-3.5 cm nodules. In nodules >3.5-5 cm, it was 89% for the first ablation and 100% for the second. For lesions >5-8 cm, ablation was up to 92%. Overall, 1-, 3- and 5-year survival rates were 89, 60, and 21%, respectively. The cumulative OS rate of group A was 89%, 66% and 34% at 1, 3 and 5 years. The cumulative OS rate of group B was 88%, 60% and 11% at 1, 3 and 5 years. The cumulative OS rate of group C was 86%, 55% and 0%. The 5-year survival rate was significantly different among the groups (p <0.001). One patient died from rupture of HCC. Upon multivariate analysis, preablation total bilirubin >1.5 mg/dL was an independent factor for predicting lower survival. Conclusions: Percutaneous MWS ablation of intermediate HCC is safe and effective in inducing large volume of necrosis in intermediate HCC nodules, providing long-term survival rates similar to transarterial chemoembolization. Preablation total bilirubin >1.5 mg/dL as expression of liver function reserve is the main factor predicting a worse outcome.

Hepatic resection compared to chemoembolization in intermediate- to advanced-stage hepatocellular carcinoma: A meta-analysis of high-quality studies. Hepatology 2018; 68:977-993.

Abstract
UNLABELLED According to the American Association for the Study of Liver Diseases (AASLD) treatment guidelines for hepatocellular carcinoma (HCC), the role of surgery has been expanded beyond the Barcelona Clinic Liver Cancer (BCLC) algorithm. We compared primary hepatectomy (PH) with transarterial chemoembolization (TACE) in patients with intermediate- to advanced-stage (BCLC stage B/C) HCC to determine the current evidence. Through a database search, we included 18 high-quality studies (one randomized controlled trial [RCT], five propensity-score matching nonrandomized comparative trials [NRCTs], and 12 NRCTs) that compared survival outcomes of 5,986 patients after PH and TACE. We found significant survival benefits for PH over TACE in BCLC stage B/C patients (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.51-0.67; P < 0.00001; I2 = 84%). According to the BCLC, both stage B and stage C patients showed significantly better overall survival (OS) for PH compared to TACE (HR, 0.53; 95% CI, 0.43-0.65; P < 0.00001; I2 = 77%; HR, 0.67; 95% CI, 0.59-0.77; P < 0.00001; I2 = 79%, respectively). Five-year survival rates for PH were significantly higher than those for TACE in BCLC stage B/C, stage B, and BCLC stage C patients (odds ratio [OR], 2.71, 2.77, and 3.03, respectively; all P < 0.00001). Survival benefits persisted across subgroup, sensitivity, and metaregression analyses; interstudy heterogeneity remained constant. CONCLUSION This meta-analysis suggests that surgical resection provides survival benefits in patients with intermediate- to advanced-stage HCC. The evidence found herein may assist in the choice of treatment modality based on diverse definitions of operability. (Hepatology 2018).

Abstract
Long non-coding RNAs (lncRNAs) have been widely reported in various cancers due to their special molecular mechanisms. LncRNA SOX21-AS1 has been discovered to be a tumor facilitator in several types of human cancers. However, the expression pattern, clinical value and biological effects in hepatocellular carcinoma (HCC) are still unknown. In this study, we detected the high expression level of SOX21-AS1 in tumor tissues and cell lines through performing qRT-PCR analysis. The prognostic value of SOX21-AS1 was identified. Moreover, the biological effects of SOX21-AS1 on HCC cell activities were evaluated by functional assays, such as MTT, colony formation assay and transwell assay. As a result, silenced SOX21-AS1 suppressed cell proliferation and metastasis, resulted in cell cycle arrest, and induced apoptosis in hepatocellular carcinoma. Mechanically, RIP was conducted to prove that SOX21-AS1 could bind with EZH2. ChIp assay was carried out and manifested that SOX21-AS1 epigenetically silenced p21 via recruiting EZH2 to the promoter of p21. Finally, rescue assays were designed and carefully conducted to investigate whether SOX21-AS1 can interact with p21 to affect hepatocellular carcinoma progression. Generally, our results suggested that SOX21-AS1 could be a potential prognostic biomarker or a therapeutic target for hepatocellular carcinoma.

Abstract
Increasing evidence demonstrates abnormal expression of long non-coding RNA (lncRNA) is closely correlated with various malignancies including hepatocellular carcinoma (HCC). The present study aims to investigate the role of lncRNA long intergenic noncoding RNA 00673 (LINC00673) in tumorigenesis of HCC. Quantitative real-time polymerase chain reaction (qRT-PCR) revealed LINC00673 was upregulated in HCC cancerous tissue and cell lines compared to adjacent normal tissue and normal liver cell lines. LINC00673 overexpression is associated with poor prognosis and low survival rate. LINC00673 silencing inhibited the proliferation, invasion and epithelial-mesenchymal transition (EMT) of HCC cells in vitro. Bioinformatics analysis revealed that miR-205 targeted 3'-UTR of LINC00673. Rescue experiments confirmed that miR-205 could reverse the effect of LINC00673 on HCC cells. In vivo xenograft tumor assay LINC00673 silencing reduced the tumor volume and weight. Taken together, findings indicate overexpression of LINC00673 promotes HCC cells progression by regulating miR-205, providing a prognostic biomarker and therapeutic target for HCC and is associated with poor survival of HCC patients.
