Abstract
Background To develop and validate an innovative predictive model that integrates multisequence magnetic resonance (MR) radiomics, deep learning features, and clinical indicators to accurately predict the recurrence of hepatocellular carcinoma (HCC) after thermal ablation. Methods This retrospective multicenter cohort study enrolled patients who were diagnosed with HCC and treated via thermal ablation. We extracted radiomic features from multisequence 3T MR images, analyzed these images using a 3D convolutional neural network (3D CNN), and incorporated clinical data into the model. Model performance was evaluated using the area under the curve (AUC) of the receiver operating characteristic (ROC) curve. Results The study included 535 patients from three hospitals, comprising 462 males and 43 females. The RDC model, which stands for the Radiomics-Deep Learning-Clinical data model, demonstrated high predictive accuracy, achieving AUCs of 0.794 in the training set, 0.777 in the validation set, and 0.787 in the test set. Statistical analysis confirmed the model's robustness and the significant contribution of the integrated features to its predictive capabilities. Conclusion The RDC model effectively predicts HCC recurrence after thermal ablation by synergistically combining advanced imaging analysis and clinical parameters. This study highlights the potential of such integrative approaches to enhance prognostic assessments in HCC patients and offers a promising tool for clinical decision-making.

Asian J Surg 2023; 46:3520-3528. [PMID: 37002048 DOI: 10.1016/j.asjsur.2023.03.070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 02/25/2023] [Accepted: 03/16/2023] [Indexed: 03/31/2023] Open
Abstract
PURPOSE To evaluate the safety and efficacy of different power modes(constant power and variable power) percutaneous microwave ablation (MWA) for treating hepatocellular carcinoma (HCC) and to predict the risk factors of recurrence after MWA. MATERIALS AND METHODS In this retrospective study, a total of 112 patients with solitary HCC were included from January 2015 to January 2021. All patients received MWA through a percutaneous approach that was guided by ultrasound, 45 patients received variable power MWA, and the remaining 67 were treated with constant power MWA. The complete ablation rates, local recurrence rates, complications, and short-term survival were analyzed. Possible risk factors for tumor recurrence were analyzed. RESULTS The complete ablation rates were 95.9% for the first ablation and 100% for the second ablation for ≤3 cm lesions. The complete ablation rates were 84.2%(95.9% versus 84.2%, p = 0.039) for the first ablation and 94.7% (100% versus 94.7%, p = 0.113) for the second ablation for 3-5 cm lesions. Local and distant recurrence rates were 18.7%(21/112) and 14.3%(16/112). The 1-, 2-year survival rates were 86.3 and 66.3%, respectively. Subgroup analysis showed that 1-, 2-year survival rates were 91.1% and 78.5% in ≤3 cm group, and were 74.4% and 40.9% in 3-5 cm group, respectively. Univariate analysis revealed that a positive correlation existed between the HBV DNA replication(p = 0.007), AFP level of pre-MWA(p = 0.001) and post-MWA(p<0.001), tumor diameter(p<0.001), irregular shape(p = 0.014), proximity to the risk location(p = 0.008), poor differentiation(p = 0.003), constant power(p = 0.028), length(p<0.001) and width of ablation zone(p = 0.001), and present complication(p<0.001), and early recurrence. Multivariate analysis identified HBV DNA replication(OR = 0.266, p = 0.036), AFP level of pre-MWA (OR = 4.001, p = 0.036), tumor diameter (OR = 2.153, p = 0.042), tumor location (OR = 0.910, p = 0.046), and width of ablation zone(OR = 2.530, p = 0.044) were independent prognosis factors causing postoperative HCC recurrence. CONCLUSION Variable power MWA of HCC appears to be a safe and effective treatment. HBV DNA, AFP level of pre-MWA, tumor diameter, tumor location, and width of ablation range appear to be independent predictors of tumor recurrence.

Abstract
Background Microwave ablation (MWA) is a standard percutaneous local therapy for hepatocellular carcinoma (HCC). Next-generation MWA is reported to create a more spherical ablation zone than radiofrequency ablation (RFA). We compared the ablation zone and aspect ratio of two 2.45 GHz MWA ablation probes; Emprint® (13G) and Mimapro® (17G). We compared the ablation zone to the applied energy after MWA in patients with hepatocellular carcinoma (HCC). Furthermore, we investigated local recurrence. Materials and Methods We included 20 patients with HCC, with an average tumour diameter of 33.2 ± 12.2 mm, who underwent MWA using Emprint®, and 9 patients who underwent MWA using Mimapro® with an average tumour diameter of 31.1 ± 10.5 mm. Both groups underwent the same ablation protocol using the same power settings. The images obtained after MWA showed the treatment ablation zone and aspect ratio, which were measured and compared using three-dimensional image analysis software. Results The aspect ratios in the Emprint® and Mimapro® groups were 0.786 ± 0.105 and 0.808 ± 0.122, respectively, with no significant difference (p = 0.604). The ablation time was significantly shorter in the Mimapro® group than in the Emprint® group, and there was no significant difference in the frequency of popping or the ablation volume. There were no significant differences in local recurrence between the two groups. Conclusion There was no significant difference in the aspect ratios of the ablation diameter, and the ablation zone was almost spherical in both cases. Mimapro® at 17G was less invasive than Emprint® at 13G.

Abstract
Background The liver resection for solitary large hepatocellular carcinoma (SLHCC) remains controversial due to the high risk of complications and recurrence after resection. This study aimed to compare the efficacy and safety of transcatheter arterial chemoembolization (TACE) plus microwave ablation (MWA) with resection for SLHCC. Methods We retrospectively analyzed a total of 148 patients who were treated with either TACE-MWA (n = 94) or resection (n = 54) for SLHCC (≥5 cm). A matched cohort composed of 86 patients was included after propensity score matching (PSM). The primary endpoint was overall survival (OS), and the secondary endpoints were progression-free survival (PFS) and safety. Results The TACE-MWA group was older with higher ALT and AST (all P < 0.05). After PSM, the 1-, 3-, and 5-year OS were 100%, 80.3%, and 51.0% in the TACE-MWA group, and 88.3%, 66.7%, and 39.4% in the liver resection group, respectively. The 1-, 3-, and 5-year PFS were 76.7%, 48.8%, and 19.6% in the TACE-MWA group, and 72%, 40.2%, and 22.6% in the liver resection group, respectively. There was no significant difference in OS and PFS between the two groups (all P > 0.05). For SLHCC patients with tumor size ≥7cm, TACE-MWA showed favorable OS than liver resection. The TACE-MWA group exhibited a lower rate of major complications and shorter hospital stay than the resection group. Conclusion TACE-MWA showed comparable efficacy to liver resection in patients with SLHCC, but better safety and shorter hospital stay. TACE-MWA might provide a longer OS than liver resection for SLHCC patients with tumor size ≥7cm.

Abstract
As novel therapeutic regimens continue to lead to increased survival of patients with lung cancer, it is imperative to remain mindful of the accompanying increase in the incidence of new primary malignancies. Although the most common secondary malignancies in patients with lung cancer have historically included colon, rectal, esophageal, and thyroid cancers, we report here two rare cases of new primary hepatocellular carcinomas in patients receiving immune checkpoint inhibitor therapy for NSCLC. In both cases, the diagnosis of hepatocellular carcinoma, rather than assuming a hepatic metastasis, was crucial for determining the appropriate approach for treatment. These cases thus underscore the importance of appropriate diagnostics to ensure that the proper therapeutics are chosen and present important considerations for the lung cancer community going forward.

Abstract
Background Microwave ablation (MWA) for hepatocellular carcinomas (HCCs) in the elderly has been the subject of new research in recent years. However, there are currently no strong lines of evidence for the prognosis following MWA treatment for HCC in the elderly. Therefore, we conducted a systematic review to assess the safety and feasibility of MWA for HCC in elderly patients. Methods Up until August 15, 2021, a comprehensive literature search was undertaken in PubMed, Scopus, CENTRAL (Cochrane Central Register of Controlled Trials), and Google Scholar databases for all published articles. Observational studies reporting the safety and feasibility of MWA for HCC in elderly patients were included. The Newcastle–Ottawa Scale (NOS) was used to measure the quality assessment. Results Our review, composed of 7 observational studies, including a total of 7,683 HCC patients, looked at the safety and feasibility of MWA for HCC in the elderly. Current lines of evidence on the risks and outcomes of MWA of HCC treatments in elderly patients are discussed. Conclusions According to our findings, elderly patients, even those with a high comorbidity index, benefited from MWA of HCC similar to younger patients. More clinical data are needed to determine selection criteria for elderly HCC patients to increase the possibility of receiving MWA as a potential lifesaving option. As such, further studies evaluating the outcomes of MWA for HCC treatment modalities in elderly patients are warranted.

Survival and recurrence rates of hepatocellular carcinoma after treatment of chronic hepatitis C using direct acting antivirals. Eur J Gastroenterol Hepatol 2022; 34:227-234.

Abstract
BACKGROUND Conflicting studies were proposed either suggested or denied the relationship between early hepatocellular carcinoma (HCC) recurrence and the use of direct-acting antivirals (DAAs) for chronic hepatitis C management. AIM OF THE STUDY To evaluate HCC recurrence rate post-DAAs and potential predictive factors.Study This prospective cohort study included all HCC patients achieved complete response attending our multidisciplinary HCC clinic, Cairo University, from November 2013 to February 2018. Group I (60 patients) who received DAAs after HCC ablation and group II (273 patients) who were DAAs-untreated. We studied factors that could play a role in HCC recurrence. RESULTS The sustained virological response rate was 88.3% among DAA-treated patients. HCC recurrence rate was 45% in the post-DAA group vs. 19% in the non-DAAs group; P < 0.001. Mean survival was significantly higher in the post-DAA group (34.23 ± 16.16 vs. 23.92 ± 13.99 months respectively; P value <0.001). There was a significant correlation between HCC recurrence rate and age, male gender, mean size of tumors and time interval between complete HCC ablation and occurrence of HCC recurrence. CONCLUSION Our study reports high rate of HCC recurrence post-DAA therapy in patients treated with transarterial chemoembolization but not in those treated with curative measures. DAA therapy after curative treatment for HCC led to significantly earlier HCC recurrence, which correlated with specific clinic-pathologic features in our prospective single-institution study. However, future independent prospective randomized studies are warranted to evaluate this correlation which may lead to a change in the current standard-of-care approach to patients with hepatitis C virus-related HCC.

Abstract
Background & Aims:
Hepatocellular carcinoma (HCC) is the fifth most common cancer
and the second leading cause of cancer-related deaths. The only definitive treatment for both HCC
and cirrhosis is liver transplantation, but long wait times in some regions and a relatively fixed
number of donor organs negatively impact access to liver transplantation. The aim of the work was
to evaluate and compare the short outcome of patients with medium-sized HCC who will undergo
percutaneous microwave ablation (MWA) alone and in combination with TACE.
Methods:
This prospective study included 40 patients with medium-sized HCC lesions who were
classified into two groups; Group A that included twenty patients treated by TACE followed by percutaneous MWA after 2 weeks and group B that included twenty patients treated by 2 sessions of
percutaneous MWA with 2 weeks interval. Full history taking, clinical examination, laboratory investigation, abdominal ultrasonography and abdominal tri-phasic computed tomography (CT) with
contrast were obtained from the two groups. Laboratory and radiological follow up of the cases
were done at 1 and 3 months after the treatment.
Results:
There was no statistically significant difference in the sociodemographic criteria, laboratory measurement and clinical criteria between the cases in the two study groups before initiation of
treatment. The response was slightly better in the combined treatment group, but it did not show a
statistically significant difference. The incidence of complications was higher in the MWA group.
Conclusion::
Hepatocellular carcinoma is a common complication of HCV related cirrhosis. Association of TACE-MWA led to better response rates than MWA with fewer complications.

On Efficacy of Microwave Ablation in the Thermal Treatment of an Early-Stage Hepatocellular Carcinoma. Cancers (Basel) 2021; 13:cancers13225784.

Abstract
Microwave ablation at 2.45 GHz is gaining popularity as an alternative therapy to hepatic resection with a higher overall survival rate than external beam radiation therapy and proton beam therapy. It also offers better long-term recurrence-free overall survival when compared with radiofrequency ablation. To improve the design and optimization of microwave ablation procedures, numerical models can provide crucial information. A three-dimensional model of the antenna and targeted tissue without homogeneity assumptions are the most realistic representation of the physical problem. Due to complexity and computational resources consumption, most of the existing numerical studies are based on using two-dimensional axisymmetric models to emulate actual three-dimensional cancers and surrounding tissue, which is often far from reality. The main goal of this study is to develop a fully three-dimensional model of a multislot microwave antenna immersed into liver tissue affected by early-stage hepatocellular carcinoma. The geometry of the tumor is taken from the 3D-IRCADb-01 liver tumors database. Simulations were performed involving the temperature dependence of the blood perfusion, dielectric and thermal properties of both healthy and tumoral liver tissues. The water content changes during the ablation process are also included. The optimal values of the input power and the ablation time are determined to ensure complete treatment of the tumor with minimal damage to the healthy tissue. It was found that a multislot antenna is designed to create predictable, large, spherical zones of the ablation that are not influenced by varying tissue environments. The obtained results may be useful for determining optimal conditions necessary for microwave ablation to be as effective as possible for treating early-stage hepatocellular carcinoma, with minimized invasiveness and collateral damages.

Abstract
PURPOSE To evaluate the rapeutic effectiveness of Angio-CT or cone-beam CT (CBCT)-guided immediate radiofrequency ablation (RFA) after transcatheter arterial chemoembolization (TACE) for large hepatocellular carcinoma (HCC). METHODS 117 large HCC patients (mean maximum diameter: 9.3 cm; range 5.3-17.7 cm) were retrospective studied and divided into Angio-CT group (n = 66 cases), CBCT group (n = 21 cases), and single TACE group (n = 30 cases) according to treatment (Angio-CT/CBCT-guided immediate RFA after TACE, single TACE, respectively). The operative time, effective radiation dose, local-regional tumor responses, overall survival (OS), and progression‑free survival (PFS) time and complications were recorded. RESULTS The operative time and effective radiation dose of Angio-CT group and CBCT group were higher than those of TACE group (P < 0.01). The local-regional tumor responses on 1-month follow-up MRI (complete response + partial response) of Angio-CT group and CBCT group were 100%, which were significantly higher than that of single TACE group (76.7%, P < 0.05). There was no significant difference in local-regional tumor responses of 1-month follow-up between Angio-CT group and CBCT group (P = 0.831). The median PFS and OS time of Angio-CT group were 14.7 ± 1.43 months and 18.21 ± 0.88 months, CBCT group were 13.9 ± 1.53 months and 17.87 ± 1.78 months, TACE group were 10.4 ± 1.21 months and 12.87 ± 0.91 months, respectively. No procedure-related major complications occurred. CONCLUSIONS MIYABI Angio-CT or CBCT-guided immediate RFA after TACE for large HCC both have more effective than single TACE. The former is worth popularizing, due to its advantages of convenience, shorter operative time, and less radiation dose for doctors.

Pathologic response translates to improved patient survival after locoregional treatment for hepatocellular carcinoma: the importance of minimally invasive microwave ablation. Surg Endosc 2020; 35:3122-3130. [PMID: 32588344 DOI: 10.1007/s00464-020-07747-6] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 06/16/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Hepatectomy or transplantation can serve as curative treatment for early-stage hepatocellular carcinoma (HCC). Unfortunately, as progression remains a reality, locoregional therapies (LRT) for curative or bridging intent have become common. Efficacy on viability, outcomes, and accuracy of imaging should be defined to guide treatment. METHODS Patients with HCC who underwent minimally invasive (MIS) microwave ablation (MWA), transarterial chemoembolization (TACE), or both (MIS-MWA-TACE) prior to hepatectomy or transplantation were identified. Tumor response and preoperative computed tomography (CT) accuracy were assessed and compared to pathology. Clinical and oncologic outcomes were compared between MIS-MWA, TACE, and MIS-MWA-TACE. RESULTS Ninety-one patients, with tumors from all stages of the Barcelona Clinic Liver Cancer (BCLC) staging, were identified who underwent LRT prior to resection or transplant. Fourteen patients underwent MIS-MWA, 46 underwent TACE, and 31 underwent both neoadjuvantly. TACE population was older; otherwise, there were no differences in demographics. Fifty-seven percent of MIS-MWA patients had no viable tumor on pathology whereas only 13% of TACE patients and 29% of MIS-MWA-TACE patients had complete destruction (p = 0.004). The amount of remaining viable tumor in the explant was also significantly different between groups (MIS-MWA: 17.2%, TACE: 48.7%, MIS-MWA-TACE: 18.6%; p ≤ 0.0001). Compared with TACE, the MIS-MWA and MIS-MWA-TACE groups had significantly improved overall survival (MIS-MWA: 99.94 months, TACE: 75.35 months, MIS-MWA-TACE: 140 months; p = 0.017). This survival remained significant with stratification by tumor size. CT accuracy was found to be 50% sensitive and 86% specific for MIS-MWA. For TACE, CT had an 82% sensitivity and 33% specificity and for MIS-MWA-TACE, there was a 42% sensitivity and 78% specificity. CONCLUSION The impact of locoregional treatments on tumor viability is distinct and superior with MIS-MWA alone and MIS-MWA-TACE offering significant advantage over TACE alone. The extent of this effect may be implicated in the improved overall survival.

Abstract
Background The aim of the study was to assess the primary efficacy of robot-assisted microwave ablation and compare it to manually guided microwave ablation for percutaneous ablation of liver malignancies. Patients and methods We performed a retrospective single center evaluation of microwave ablations of 368 liver tumors in 192 patients (36 female, 156 male, mean age 63 years). One hundred and nineteen ablations were performed between 08/2011 and 03/2014 with manual guidance, whereas 249 ablations were performed between 04/2014 and 11/2018 using robotic guidance. A 6-week follow-up (ultrasound, computed tomography and magnetic resonance imaging) was performed on all patients. Results The primary technique efficacy outcome of the group treated by robotic guidance was significantly higher than that of the manually guided group (88% vs. 76%; p = 0.013). Multiple logistic regression analysis indicated that a small tumor size (≤ 3 cm) and robotic guidance were significant favorable prognostic factors for complete ablation. Conclusions In addition to a small tumor size, robotic navigation was a major positive prognostic factor for primary technique efficacy.

Abstract
Purpose Percutaneous ablation techniques, including microwave ablation (MWA) and radiofrequency ablation (RFA), have become important minimally invasive treatment options for liver cancer. This systematic review compared MWA with RFA for treatment of liver cancer. Methods The systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A systematic search of MEDLINE, EMBASE, and Cochrane Central Register of Controlled Trials was conducted for randomized and observational studies published from 2006 onwards. A random-effects model was used for meta-analyses and local tumor progression (LTP), technique efficacy, overall survival (OS), disease-free survival (DFS), intrahepatic de novo lesions (IDL), extrahepatic metastases (EHM), length of stay (LOS), and complications were analyzed. Subgroup and sensitivity analyses were also conducted. Results Of 1379 studies identified, 28 randomized and observational studies met inclusion criteria. The main analysis demonstrated that LTP was significantly reduced by 30% with MWA versus RFA (RR=0.70; P=0.02) (all studies) and by 45% with MWA versus RFA (RR=0.55; P=0.007) (randomized studies only). There were no significant differences between MWA and RFA for other efficacy and safety outcomes. Higher frequency (2450 MHz) and larger tumor size (≥2.5 cm) are amongst variables that may be associated with improved outcomes for MWA. Sensitivity analyses were generally congruent with the main results. Conclusion MWA is at least as safe and effective as RFA for treating liver cancer and demonstrated significantly reduced LTP rates. Future studies should assess time and costs associated with these two treatment modalities.

Abstract
BACKGROUND Videolaparoscopic (VL) microwave ablation (MWA) is not included in most of the international guidelines as a therapeutic option for hepatocellular carcinoma (HCC). Aim of this study was to assess the safety of VL MWA in patients with HCC for whom resection or percutaneous ablation is unsuitable. METHODS A retrospective analysis was performed on a prospective database of patients with HCC treated with VL MWA at our institution from 2009 to 2016. Patient demographics, operational characteristics, and complications were recorded. Statistical analysis was performed to identify safety profile, overall survival and recurrence rate. RESULTS A total of 815 VL MWA were performed in 674 patients with a mean age of 64 years. Patients had a mean Model for End-stage Liver Disease score of 10 (±3); 32.8% were Child B, 44.1% Barcelona Clinic Liver Cancer B-C. Perioperative mortality was 0.4%. Overall morbidity was 30.8%, with Dindo-Clavien complications ≥3 in 2%. The median length of stay was 2 days. In 43.1% VL MWA was the first-line therapy. Overall 1-, 3-, and 5-year survival rates were 81.9%, 54.9%, and 35.9%. CONCLUSIONS The present is the largest series of VL ablation and the bigger number of patients with HCC treated with MW reported nowadays. It confirms the safety of a minimally invasive procedure for patients with HCC when resection or percutaneous ablation is not feasible.

Liver stiffness measurement changes following hepatocellular carcinoma treatment with percutaneous microwave ablation or transarterial chemoembolization: a cohort study. Eur J Gastroenterol Hepatol 2019; 31:685-691.

Abstract
BACKGROUND Liver stiffness increases after the development of hepatocellular carcinoma (HCC). Transient elastography for liver stiffness measurement (LSM) using fibroscan is a simple noninvasive method of proven efficacy. This study aims to assess the changes in LSM following HCC treatment. PATIENTS AND METHODS This study included 150 patients with hepatitis C virus related HCC attending the multidisciplinary HCC clinic, Kasr Al-Ainy Hospital between March 2014 and October 2015 who underwent either transarterial chemoembolization (TACE) or microwave ablation (MWA). Baseline LSM was carried out 3 and 6 months after treatment. The response rate was calculated according to the modified Response Evaluation Criteria in Solid Tumors criteria; overall survival and LSM changes were then compared between the two procedures. RESULTS MWA showed higher rates of complete ablation (77.4%) than did TACE (31.7%) (P=0.004). Increase in LSM 3 and 6 months after treatment was statistically significant in the TACE group (P<0.001) but not in the MWA group (P=0.4). Patients who showed complete ablation had statistically significant lower baseline LSM than those with incomplete ablation, and their 6 months increase in LSM was also significantly lower. Logistic regression revealed that with each unit increase in baseline stiffness, 3% reduction in the odds of complete ablation is expected, and this did not change after controlling for the type of treatment. Child-Pugh class, number, and size of HCCs were our independent prognostic factors by Cox proportional analysis. CONCLUSION The increase in LSM is significant after TACE than after MWA. Moreover, lower pre-ablation LSM is a predictor of complete ablation.

Abstract
BACKGROUND Patients with a single hepatocellular carcinoma (HCC) ≤3 cm and preserved liver function have the highest likelihood to be cured if treated. The most adequate treatment methods are yet a matter that is debated. METHODS We reviewed the literature about open anatomic resection (AR), laparoscopic liver resection (LLR), and percutaneous thermal ablation (PTA). RESULTS PTA is effective as resection for HCC < 2 cm, when they are neither subcapsular nor perivascular. PTA in HCC of 2-3 cm is under evaluation. AR with the removal of the tumor-bearing portal territory is recommended for HCC > 2 cm, except for subcapsular ones. In comparison with open surgery, LRR has better short-term outcomes and non-inferior long-term outcomes. LLR is standardized for superficial limited resections and for left-sided AR. CONCLUSIONS According to the available evidences, the following therapeutic proposal can be advanced. Laparoscopic limited resection is the standard for any subcapsular HCC. PTA is the first-line treatment for deep-located HCC < 2 cm, except for those in contact with Glissonean pedicles. Laparoscopic AR is the standard for deep-located HCC of 2-3 cm of the left liver, while open AR is the standard for deep-located HCC of 2-3 cm in the right liver. HCC in contact with Glissonean pedicles should be scheduled for resection (open or laparoscopic) independent of their size. Liver transplantation is reserved to otherwise untreatable patients or as a salvage procedure at recurrence.

Abstract
OBJECTIVE To evaluate the safety and long-term outcomes of microwave ablation (MWA) combined with transarterial chemoembolization (TACE) in a single stage for the treatment of hepatocellular carcinoma (HCC) with a maximum diameter of 5.0-10.0 cm. METHODS From January 2013 to December 2016, 84 consecutive HCC patients with cirrhosis from two medical centers who underwent MWA-TACE as a first-line treatment for up to three HCCs with maximum diameters of 5.0-10.0 cm were included. Feasibility, safety and effectiveness were evaluated. Recurrence-free survival (RFS) and overall survival (OS) were analyzed using the Kaplan-Meier method. Cox regression models were used to identify the prognostic factors. RESULTS The technique was successfully performed in all the patients. Grade 3 complications consisted of two cases of hemoperitoneum requiring blood transfusions and embolization. The cumulative incidence of local tumor progression was 25.8% at 3 years, with tumor size found to be the only significant predictive factor (p = .007). The cumulative incidence of OS was 81%, 68% and 49% at 1, 2 and 3 years, respectively. According to the Cox proportional hazards model analysis, serum AFP level, Child-Pugh class and tumor number were significant prognostic factors for OS. CONCLUSION MWA-TACE is a safe, feasible and effective therapy for the treatment of 5.0- to 10.0-cm HCC lesions in patients with cirrhosis.

Abstract
INTRODUCTION Survival of hepatocellular carcinoma (HCC) differs between regions and countries according to the different underlying factors and the degree of standard of care that enables early diagnosis and management. Our aim was to identify the most potent predictive factors of survival in Egyptian HCC patients receiving curative or palliative treatments. PATIENTS AND METHODS This retrospective study included 1302 HCC patients attending the HCC multidisciplinary clinic, Cairo University, between February 2009 and December 2016. Clinical, laboratory, tumor characteristics, and treatment data were collected. Prognostic scores for each of the treatment categories, curative or palliative, were developed using routine laboratory tests. RESULTS Patients were predominantly men, mean age 57.79±7.56 years. All cases developed HCC in addition to cirrhosis, mainly hepatitis C virus-related (88.2%). Most of the patients were Child-Pugh A (56.8%) or B (34.4%) and had single lesions. Transarterial chemoembolization was the most common line of treatment (42.08%). The overall median survival was 18.3 months from the date of diagnosis. Cigarette smoking, Child-Pugh score, performance status, number and size of the focal lesion, α-fetoprotein, and application of a specific treatment, particularly curative treatment, were the significant independent prognostic factors for survival. We found no impact of diabetes mellitus or hypertension on survival. Multidisciplinary HCC clinic predictive scores of survival after palliative and curative treatments were developed including independent prognostic factors, age, and portal vein status. CONCLUSION A new Egyptian prognostic score of tumor and patients factors can predict the survival of patients with HCC after palliative and curative treatments.

Abstract
Background Percutaneous ablation techniques offer a vast armamentarium for local, minimally invasive treatment of liver tumors, nowadays representing an established therapeutic option, which is integrated in treatment algorithms, especially for non-resectable liver tumors. The results of ablative treatment compare very well to surgical treatment in liver lesions, and confirm that these techniques are a valuable option for bridging for transplantation. Different techniques have been established to perform tumor ablation, and the feasibility varies according to the procedure and technical skills of the operator, depending on the size and location of the liver lesion. In recent years, stereotactic multi-needle techniques using 3D trajectory planning, general anesthesia, and tube disconnection during needle placement have had a strong impact on the application range of ablation for liver tumors. Conclusion It is well known that creating a sufficient ablation margin and overlapping ablation zones is one key issue to enable ablation of large liver lesions with tumor-free margins (A0 ablation in analogy to R0 resection). Image fusion during treatment and follow-up assure highly accurate staging procedures and interventional planning. Novel aspects Review on the standards in ablation techniques for the treatment of liver tumors. Update on different ablation techniques, indications, and contraindications for percutaneous liver tumor treatment. Summary of recently published reports on liver tumor ablation.

Abstract
Background Limited therapies are available for large (≥40 mm) unresectable hepatocellular carcinoma (HCC). Currently, the standard treatment with transarterial chemoembolisation (TACE) is unsatisfactory with high recurrence rate and limited effect on survival. Laser Ablation (LA) has emerged as a relatively new technique characterized by high efficacy and good safety. This study is aimed to evaluate the efficacy of LA in comparison to TACE in patients with large HCC. Methods Eighty-two patients with a single HCC nodule ≥40 mm (BCLC stage A or B) were enrolled in this case-control study. Forty-one patients were treated with LA and 41 patients were treated with TACE. Response to therapy was evaluated according to the mRECIST criteria. Survival was calculated with Kaplan-Meier from the time of cancer diagnosis to death with values censored at the date of the last follow-up. Results Twenty-six (63.4%) and 8 (19.5%) patients had a complete response after LA and TACE, respectively (p < 0.001). Subsequently we stratified the HCCs in 3 categories according to the nodule size: 40–50 mm, 51–60 mm, and >60 mm. LA resulted superior to TACE especially in nodules ranging between 51 and 60 mm in diameter, with a complete response rate post-LA and post-TACE of 75% and 14.3%, respectively (p = 0.0133). The 36 months cumulative survival rate in patients treated with LA and TACE was 55.4% and 48.8%, respectively. The disease recurrence rates after LA and TACE were 19.5% and 75.0%, respectively. Conclusions LA is a more effective therapeutic option than TACE in patients with solitary large HCC.

Abstract
Percutaneous treatment of hepatocellular carcinoma (HCC) encompasses a vast range of techniques, including monopolar radiofrequency ablation (RFA), multibipolar RFA, microwave ablation, cryoablation and irreversible electroporation. RFA is considered one of the main curative treatments for HCC of less than 5 cm developing on cirrhotic liver, together with surgical resection and liver transplantation. However, controversies exist concerning the respective roles of ablation and liver resection for HCC of less than 3 to 5 cm on cirrhotic liver. In line with the therapeutic algorithm of early HCC, percutaneous ablation could also be used as a bridge to liver transplantation or in a sequence of upfront percutaneous treatment, followed by transplantation if the patient relapses. Moreover, several innovations in ablation methods may help to efficiently treat early HCC, initially considered as "non-ablatable", and might, in some cases, extend ablation criteria beyond early HCC, enabling treatment of more patients with a curative approach.

Abstract
Primary liver cancer, mainly hepatocellular carcinoma, is one of the most common malignancies worldwide. Surgical management, either resection or transplantation, is considered definitive treatment, however, less than 20% of patients are ultimately candidates. Thermal ablation modalities such as radiofrequency ablation and microwave ablation have evolved such that these modalities have been applied with curative intent. Moreover, thermal ablation has demonstrated efficacy in treating early-stage tumors and can be offered as first-line treatment in patients with uncomplicated disease. Attributing to refinements in technology and techniques, recent studies evaluating stereotactic ablative body radiotherapy have shown promising results, while irreversible electroporation, an emerging modality, may further expand the role of ablative therapy in treating potentially resectable hepatocellular carcinoma.

Abstract
BACKGROUND There is significant uncertainty in the treatment of intermediate-stage hepatocellular carcinoma which is defined by the Barcelona Clinic Liver Cancer (BCLC) as hepatocellular carcinoma stage B with large, multi-nodular, Child-Pugh status A to B, performance status 0 to 2, and without vascular occlusion or extrahepatic disease. OBJECTIVES To assess the comparative benefits and harms of different interventions used in the treatment of intermediate-stage hepatocellular carcinoma (BCLC stage B) through a network meta-analysis and to generate rankings of the available interventions according to their safety and efficacy. However, we found only one comparison. Therefore, we did not perform the network meta-analysis, and we assessed the comparative benefits and harms of different interventions versus each other, or versus placebo, sham, or no intervention (supportive treatment only) using standard Cochrane methodology. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, Science Citation Index Expanded, World Health Organization International Clinical Trials Registry Platform, and randomised clinical trials registers to September 2016 to identify randomised clinical trials on hepatocellular carcinoma. SELECTION CRITERIA We included only randomised clinical trials, irrespective of language, blinding, or publication status, in participants with intermediate-stage hepatocellular carcinoma, irrespective of the presence of cirrhosis, size, or number of the tumours (provided they met the criteria of intermediate-stage hepatocellular carcinoma), of presence or absence of portal hypertension, of aetiology of hepatocellular carcinoma, and of the future remnant liver volume. We excluded trials which included participants who had previously undergone liver transplantation. We considered any of the various interventions compared with each other or with no active intervention (supportive treatment only). We excluded trials which compared variations of the same intervention: for example, different methods of performing transarterial chemoembolisation. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We calculated the hazard ratio (HR) with 95% confidence intervals (CI) using both fixed-effect and random-effects models based on available-participant analysis with Review Manager. We assessed risk of bias according to Cochrane, controlled risk of random errors with Trial Sequential Analysis using Stata, and assessed the quality of the evidence using GRADE. MAIN RESULTS Three randomised clinical trials, including 430 participants, met the inclusion criteria for this review; however, data from two trials with 412 participants could be included in only one primary outcome (i.e. mortality). All three trials were at high risk of bias. All three trials included supportive care as cointervention. The comparisons included in the two trials reporting on mortality were: systemic chemotherapy with sorafenib versus no active intervention; and transarterial chemoembolisation plus systemic chemotherapy with sorafenib versus transarterial chemoembolisation alone. The trials did not report the duration of follow-up; however, it appeared that the participants were followed up for a period of about 18 to 30 months. The majority of the participants in the trials had cirrhotic livers. The trials included participants with intermediate-stage hepatocellular carcinoma arising from viral and non-viral aetiologies. The trials did not report the portal hypertension status of the participants. The mortality was 50% to 70% over a median follow-up period of 18 to 30 months. There was no evidence of difference in mortality at maximal follow-up between systemic chemotherapy versus no chemotherapy (hazard ratio 0.85, 95% CI 0.60 to 1.18; participants = 412; studies = 2; I2 = 0%; very low quality evidence). A subgroup analysis performed by stratifying the analysis by the presence or absence of transarterial chemoembolisation as cointervention did not alter the results. None of the trials reported on serious adverse events other than mortality, health-related quality of life, recurrence of hepatocellular carcinoma, or length of hospital stay. One of the trials providing data was funded by the pharmaceutical industry, the other did not report the source of funding, and the trial with no data for the review was also funded by the pharmaceutical industry. We found two ongoing trials. AUTHORS' CONCLUSIONS Currently, there is no evidence from randomised clinical trials that people with intermediate-stage hepatocellular carcinoma would benefit from systemic chemotherapy with sorafenib either alone or when transarterial chemoembolisation was used as a cointervention (very low quality evidence). We need high-quality randomised clinical trials designed to measure differences in clinically important outcomes (e.g. all-cause mortality or health-related quality of life).

Abstract
Introduction: Local ablative therapy and trans arterial chemoembolization (TACE) are applied to ablate non resectable hepatocellular carcinoma (HCC). Combination of both techniques has proven to be more effective. We aimed to study combined ablation techniques and assess survival benefit comparing TACE with radiofrequency (RFA) versus TACE with microwave (MWA) techniques. Methods: We retrospectively studied 22 patients who were ablated using TACE-RFA and 45 with TACE-MWA. All were classified as Child A-B and lesions did not exceed 5 cm in diameter. TACE was followed within two weeks by either RFA or MWA. We recorded total and partial ablation rates and complication rates. Survival analysis was then performed. Results: TACE-MWA showed a higher tendency to provide complete response rates than TACE-RFA (P 0.06). This was particularly evident with lesions sized 3-5 cm (P 0.01). Rates of complications showed no significant difference between the groups. Overall median survival was 27 months. The overall actuarial probability of survival was 80.1% at 1 year, 55% at 2 years, and 36.3% at 3 years. The recurrence free survival at 1 year, 2years and 3 years for the TACE-RFA group was 70%, 42% and 14% respectively and for TACE-MWA group 81.2%, 65.1% and 65.1% without any significant difference (P 0.1). In relation to the size of focal lesions, no statistically significant difference in the survival rates was detected between the groups. Conclusion: TACE-MWA led to better response rates than TACE-RFA with tumors 3-5 cm, with no difference in survival rates.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide and the third most common cause of cancer-related deaths. Hepatic resection and liver transplantation are considered to be the preferred treatment for HCC. However, as novel therapeutic options such as image-guided locoregional therapies have emerged and been refined, the manner in which HCC is treated has changed dramatically compared with what it was considered just 2 decades earlier. SUMMARY This study reviews the current results of various image-guided locoregional therapies for treating HCC, especially focusing on thermal ablative and transarterial techniques. KEY MESSAGE Advances in image-guided locoregional therapies, including local ablative therapy and transarterial therapy, have led to a major breakthrough in the management of HCC. Both survival rates and cure rates of patients with HCC have improved markedly since the introduction of these techniques. PRACTICAL IMPLICATIONS Radiofrequency ablation is currently considered as an alternative to surgical resection for patients with early-stage HCC. A newer technique of ablation such as microwave ablation is increasingly being used, especially for large HCC. Transarterial chemoembolization has become a standard care for asymptomatic patients with multinodular tumors in intermediate-stage disease, and transarterial radioembolization has become the method of choice in HCC cases with portal vein thrombosis. Moreover, combination treatment modalities, such as thermal-based ablation combined with transarterial chemoembolization or 125I seed implant brachytherapy, may further broaden their clinical indications for HCC. Moreover, use of localized radiation in combination with thermal ablation has been reported to improve tumor control and long-term survival.

Abstract
PURPOSE To evaluate the safety and efficacy of microwave (MW) ablation combined with transarterial chemoembolization in a single stage for the treatment of large (≥ 5 cm) hepatocellular carcinoma (HCC). MATERIALS AND METHODS From March 2013 to January 2015, 66 patients (54 men and 12 women; mean age, 54 y; range, 29-83 y) with 72 large HCC lesions were included in this study. Eighteen (27.3%) had Barcelona Clinic Liver Cancer class B disease, and 48 (72.7%) had class C disease. Seventy-nine percent of patients (n = 52) had hepatitis B virus infection. The average tumor size was 9.0 cm ± 3.9, ranging from 5 to 19 cm. MW ablation was performed under ultrasound guidance, immediately followed by chemoembolization. Local tumor response, progression-free survival (PFS), and overall survival (OS) were assessed. RESULTS The technique was successfully performed in all patients. Complete response (CR) was achieved in 28 cases (42.4%), and partial response (PR) was achieved in 34 cases (51.5%) at 1 month after the procedure. The objective response rate (ie, CR plus PR) was 93.9%. Median PFS and OS times were 9 months and 21 months, respectively. The 6-, 12-, and 18-month OS rates were 93.9%, 85.3%, and 66.6%, respectively. Hemorrhage was detected in three patients and arteriovenous fistula in two patients after MW ablation; all were promptly treated with embolization. There were no liver abscesses, bile-duct injuries, or other major procedure-related complications. CONCLUSIONS MW ablation immediately followed by chemoembolization is safe and effective in the treatment of large HCC lesions.

Abstract
Surveillance programs and widespread use of medical imaging have increased the detection of hepatic tumors. When feasible, surgical resection is widely accepted as the curative treatment of choice, but surgical morbidity and mortality has spurred the development of minimally invasive ablative technologies over the last 2 decades. Microwave ablation has emerged as a promising thermal ablation modality with improving oncologic efficacy due to technical improvements and image guidance strategies. This article provides an overview of microwave application in liver tumors, and we discuss currently available equipment, clinical efficacy, and safety and provide comparisons with other commonly used therapies. This article also introduces advanced ablative techniques and combination therapies that may help achieve precise ablation and further enhance the efficacy of microwave ablation.

Abstract
PURPOSE Radiofrequency ablation (RFA) and microwave ablation (MWA) are the two main percutaneous techniques for the treatment of unresectable hepatocellular carcinoma (HCC). However, to date, studies comparing the two therapies have provided discordant results. The aim of this meta-analysis is to evaluate the efficacy and safety of the two treatments for HCC patients. MATERIALS AND METHODS A computerised bibliographic search was performed on PubMed/MEDLINE, Embase, Google Scholar and Cochrane library databases. The rates of complete response (CR), local recurrence (LRR), 3-year survival (SR) and major complications were compared between the two treatment groups by using the Mantel-Haenszel test in cases of low heterogeneity or the DerSimonian and Laird test in cases of high heterogeneity. Sources of heterogeneity were investigated using subgroup analyses. In order to confirm our finding, sensitivity analysis was performed restricting the analysis to high-quality studies. RESULTS One randomised controlled trial (RCT) and six retrospective studies with 774 patients were included in the meta-analysis. A non-significant trend of higher CR rates in the patients treated with MWA was found (odds ratio (OR) = 1.12, 95% confidence interval (CI) 0.67-1.88, p = 0.67]. Overall LRR was similar between the two treatment groups (OR 1.01, 95% CI 0.53-1.87, p = 0.98) but MWA outperformed RFA in cases of larger nodules (OR 0.46, 95% CI 0.24-0.89, p = 0.02). 3-year SR was higher after RFA without statistically significant difference (OR 0.95, 95% CI 0.58-1.57, p = 0.85). Major complications were more frequent, although not significantly, in MWA patients (OR 1.63, 95% CI 0.88-3.03, p = 0.12). CONCLUSIONS Our results indicate a similar efficacy between the two percutaneous techniques with an apparent superiority of MWA in larger neoplasms.

Abstract
Hepatocellular carcinoma (HCC) is the sixth-most common type of cancer worldwide. The only definitive treatment modalities capable of achieving a cure are hepatic resection and hepatic transplantation. However, most patients are not candidates for these therapies. Overall, treatment options are driven by the stage of HCC. Early-stage disease is treated with ablative therapies, with radiofrequency ablation the ablative therapy of choice. Microwave ablation and irreversible electroporation are the other upcoming alternatives. Intermediate-stage disease is managed with transarterial chemoembolization (TACE), while advanced-stage disease is managed by sorafenib, with TACE and radioembolization as other alternatives.
