Abstract
Hepatocellular carcinoma (HCC) is a growing health concern projected to cross over a million cases worldwide by 2025. HCC presents a significant burden of disease in Middle East and North African (MENA) countries due to a high prevalence of risk factors such as hepatitis C and B infections and rising incidence of non-alcoholic steatohepatitis and non-alcoholic fatty liver disease. In August 2022, an advisory meeting consisting of experts from 5 MENA countries was convened in an attempt to provide consensus recommendations on HCC screening, early diagnosis, current treatment modalities and unmet medical needs in the region. Data were collected from a pre-meeting survey questionnaire and responses analysed and presented during the advisory meeting. This review summarizes the evidence discussed at the meeting and provides expert recommendations on the management of HCC. The 2022 update of Barcelona clinic liver cancer (BCLC) staging and treatment strategy and its implementation in the MENA region was extensively discussed. A key consensus of the expert panel was that multidisciplinary care is crucial to effective patient management that results in better clinical outcomes and overall survival of the patient. The panel recommended the use of predictive and early response biomarkers to guide clinicians in arriving at more effective therapeutic decisions. The experts also emphasized the role of robust screening/surveillance systems, population-based registries, effective referral pathways and standardization of guidelines to ensure the successful management of HCC in the region.

Abstract
Hepatocellular carcinoma (HCC) is the sixth most common primary malignancy worldwide, and the third most common cause of death among cancers worldwide. HCC occurs in several pre-existing conditions, including hepatitis C, hepatitis B virus, and non-alcoholic cirrhosis. Egypt used to be the country with the heaviest hepatitis C virus (HCV) burden. The relationship between HCV and HCC is an important research area. In Egypt, HCC is a significant public health problem. A possible cause for the increasing rates of detection of HCC in Egypt is the mass screening program that was carried by the government for detecting and treating HCV. A multidisciplinary approach is now widely applied to HCC management in health centers all over Egypt. Different treatment modalities are available in Egypt, with success rates comparable to global rates. The Egyptian health authorities have made the elimination of HCV from Egypt a special priority, and this approach should lead to a decrease in number of HCC cases in the near future. In this article we review the current situation of HCC in Egypt, including epidemiological aspects, relevant risk factors for HCC development, strategies, and efforts established by health authorities for the screening and prevention of both HCV and HCC in Egypt. We highlight the different modalities for HCC treatment.

The initiation, standardization and proficiency (ISP) phases of the learning curve for minimally invasive liver resection: comparison of a fellowship-trained surgeon with the pioneers and early adopters. Surg Endosc 2020; 35:5268-5278. [PMID: 33174100 DOI: 10.1007/s00464-020-08122-1] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Accepted: 10/21/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Using the Ideal Development Exploration Assessment and Long-term study (IDEAL) paradigm, Halls et al. created risk-adjusted cumulative sum (RA-CUSUM) curves concluding that Pioneers (P) and Early Adopters (EA) of minimally invasive (MI) liver resection obtained similar results after fewer cases. In this study, we applied this framework to a MI Hepatic-Pancreatic and Biliary fellowship-trained surgeon (FT) in order to assess where along the curves this generation fell. METHODS The term FT was used to designate surgeons without previous independent operative experience who went from surgical residency directly into fellowship. Three phases of the learning curve were defined using published data on EAs and Ps of MI Hepatectomy, including phase 1 (initiation) (i.e., the first 17 or 50), phase 2 (standardization) (i.e., cases 18-46 or 1-50) and phase 3 (proficiency) (i.e., cases after 46, 50 or 135). Data analysis was performed using the Social Science Statistics software ( www.socscistatistics.com ). Statistical significance was defined as p < .05. RESULTS From November 2007 until April 2018, 95 MI hepatectomies were performed by a FT. During phase 1, the FT approached larger tumors than the EA group (p = 0.002), that were more often malignant (94.1%) when compared to the P group (52.5%) (p < 0.001). During phase 2, the FT operated on larger tumors and more malignancies (93.1%) when compared to the Ps (p = 0.004 and p = 0.017, respectively). However, there was no difference when compared to the EA. In the phase 3, the EAs tended to perform more major hepatectomies (58.7) when compared to either the FT (30.6%) (p = 0.002) or the P's cases 51-135 and after 135 (35.3% and 44.3%, respectively) (both p values < 0.001). When compared to the Ps cases from 51-135, the FT operated on more malignancies (p = 0.012), but this was no longer the case after 135 cases by the Ps (p = 0.164). There were no statistically significant differences when conversions; major complications or 30- and 90-day mortality were compared among these 3 groups. DISCUSSION Using the IDEAL framework and RA-CUSUM curves, a FT surgeon was found to have curves similar to EAs despite having no previous independent experience operating on the liver. As in our study, FTs may tend to approach larger and more malignant tumors and do more concomitant procedures in patients with higher ASA classifications than either of their predecessors, without statistically significant increases in major morbidity or mortality. CONCLUSION It is possible that the ISP (i.e., initiation, standardization, proficiency) model could apply to other innovative surgical procedures, creating different learning curves depending on where along the IDEAL paradigm surgeons fall.

Abstract
BACKGROUND Blood flow factors, such as congestion or ischemia after hepatectomy, have a significant impact on liver regeneration, but with the popularization of precise hepatectomy technology, segmental hepatectomy without congestion or ischemia has become the preferred treatment. Our aim is to investigate the factors affecting liver regeneration after hepatectomy without blood flow changes, and to provide clinical evidence for surgeons on the timing of second hepatectomy for cirrhosis patients with hepatocellular carcinoma (HCC). METHODS This study retrospectively analyzed data from patients who underwent right hepatectomy without middle hepatic vein (MHV) in West China Hospital between January 2016 and January 2018. Eighteen living-donors without MHV as normal group and 45 HCC patients, further classified into 3 subgroups based on the severity of fibrosis using the Scheure system. Demographic data, pre- and postoperative liver function indexes, and remnant liver volume (RLV) were retrospectively compared. We also analyzed the remnant liver regeneration rate (RLRR) post-operatively in each group. The significant indexes in univariate analysis were further analyzed using both receiver operating characteristic (ROC) analysis and multivariate regression analysis. RESULTS Liver regeneration occurred in both living-donor and HCC groups after hepatectomy; the RLRRs at 1 month were 59.46 ± 10.39% and 57.27 ± 4.77% (P = .509), respectively. Regeneration in the cirrhosis group occurred more slowly and less completely compared with that in other groups. The regeneration rate in the first 6 months showed rapid increase and the RLRR reached above 70% in cirrhosis group. Multivariate and ROC analyses revealed that Alb and the hepatic fibrosis grade in the early postoperative period were significant predictors of remnant liver regeneration. CONCLUSION The liver regenerated in all HCC patients; however, regeneration was significantly slower and less complete compared with the normal liver, especially in the patients with cirrhosis. Therefore, it can be concluded that the degree of liver fibrosis is a major predictor of liver regeneration. Furthermore, the optimal time for second resection in recurrent HCC patients with cirrhosis was 6 months after the first operation.

Local Ablation Does Not Worsen Perioperative Outcomes After Liver Transplant for Hepatocellular Carcinoma. AJR Am J Roentgenol 2019; 213:702-709. [PMID: 31120785 DOI: 10.2214/ajr.18.20993] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/12/2022]
Abstract
OBJECTIVE. Local ablation of hepatocellular carcinoma (HCC) before liver transplant has important advantages, such as preventing disease progression, tumor downstaging, and offering a test of time. However, it might render liver transplant more technically demanding. Thus far, its potential effect on liver transplant outcomes is still unknown, and, therefore, the current study was performed. MATERIALS AND METHODS. Patients who underwent liver transplant for HCC at a single tertiary referral center between 2008 and 2016 were included and retrospectively analyzed. Patients who underwent liver resection and local ablation before liver transplant were excluded. Patients treated with local ablation before liver transplant were compared with those not treated with local ablation, both before and after propensity score matching. In addition, the local ablation group was compared with patients who underwent primary resection before liver transplant. Posttreatment mortality and morbidity were determined, and overall and disease-free survival rates were calculated. RESULTS. In total, 182 patients were included. Twenty-six patients underwent resection but not local ablation before liver transplant. Of the remaining 156 patients, 66 (42%) underwent local ablation before liver transplant and 90 (58%) did not. Perioperative mortality and morbidity were similar in both groups before and after propensity score matching (8% and 74% in the local ablation group vs 10% and 83% in the non-local ablation group, p = 0.60 and 0.17, respectively). In addition, no significant differences in long-term outcomes were observed between the groups before and after propensity score matching. Also, no differences were observed in outcomes in the local ablation group versus the liver resection group. CONCLUSION. Local ablation before liver transplant does not have a negative effect on outcomes after liver transplant for HCC.

Curative salvage liver transplantation in patients with cirrhosis and hepatocellular carcinoma: An intention-to-treat analysis. Hepatology 2018; 67:204-215. [PMID: 28806477 DOI: 10.1002/hep.29468] [Citation(s) in RCA: 37] [Impact Index Per Article: 6.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Revised: 07/24/2017] [Accepted: 08/06/2017] [Indexed: 12/07/2022]
Abstract
UNLABELLED The salvage liver transplantation (SLT) strategy was conceived for initially resectable and transplantable (R&T) hepatocellular carcinoma (HCC) patients, to try to obviate upfront liver transplantation, with the "safety net" of SLT in case of postresection recurrence. The SLT strategy is successful or curative when patients are recurrence free following primary resection alone, or after SLT for recurrence. The aim of the current study was to determine the SLT strategy's potential for cure in R&T HCC patients, and to identify predictors for its success. From 1994 to 2012, all R&T HCC patients with cirrhosis were enrolled in the SLT strategy. An intention-to-treat (ITT) analysis was used to determine this strategy's outcomes and predictors of success according to the above definition. In total, 110 patients were enrolled in the SLT strategy. Sixty-three patients (57%) had tumor recurrence after initial resection, and in 30 patients SLT could be performed (recurrence transplantability rate = 48%). From the time of initial resection, ITT 5-year overall and disease-free survival rates were 69% and 60%, respectively. The SLT strategy was successful in 60 patients (56%), either by resection alone (36%), or by SLT for recurrence (19%). Preresection predictors of successful SLT strategy at multivariate analysis included Model for End-Stage Liver Disease (MELD) score >10, and absence of neoadjuvant transarterial chemoembolization (TACE). Additional postresection predictive factors were absence of postresection morbidity, and T-stage 1-2 at the resection specimen. CONCLUSION The SLT strategy is curative in only 56% of cases. Higher MELD score at inception of the strategy and no pre-resection TACE are predictors of successful SLT strategy. (Hepatology 2018;67:204-215).

Abstract
The surgical treatments of hepatocellular carcinoma (HCC) in a cirrhotic liver include both hepatic resection and liver transplant. While the liver transplant is considered as a golden therapy, it has some obstacles including shortage of organs especially living donors, economic circumstances, and the progression of a tumor while waiting for the transplant so the second choice which is resection should have a role. In this study, 84 patients with HCC (who were legible for transplant according to Milan and extended selection criteria) were enrolled for hepatic resection. The outcome including complication and the oncologic outcome was evaluated. We followed our patients for 15 months as a median follow-up (range from 3 to 50 months); we noticed 10 tumor relapse (11.7%) and seven lost (8.3%). We also noticed no recurrence. Patients' overall survival showed a median of 15 and 50 months, respectively. We can conclude that there is reasonability for HR as an effective optional treatment for patients with HCC who are legible for transplant particularly for patients with a Child-A scoring.

Abstract
BACKGROUND AND OBJECTIVE For more than a decade, computer-assisted surgical systems have been helping surgeons to plan liver resections. The most widespread strategies to plan liver resections are: drawing traces in individual 2D slices, and using a 3D deformable plane. In this work, we propose a novel method which requires low level of user interaction while keeping high flexibility to specify resections. METHODS Our method is based on the use of Bézier surfaces, which can be deformed using a grid of control points, and distance maps as a base to compute and visualize resection margins (indicators of safety) in real-time. Projection of resections in 2D slices, as well as computation of resection volume statistics are also detailed. RESULTS The method was evaluated and compared with state-of-the-art methods by a group of surgeons (n=5, 5-31 years of experience). Our results show that theproposed method presents planning times as low as state-of-the-art methods (174 s median time) with high reproducibility of results in terms of resected volume. In addition, our method not only leads to smooth virtual resections easier to perform surgically compared to other state-of-the-art methods, but also shows superior preservation of resection margins. CONCLUSIONS Our method provides clinicians with a robust and easy-to-use method for planning liver resections with high reproducibility, smoothness of resection and preservation of resection margin. Our results indicate the ability of the method to represent any type of resection and being integrated in real clinical work-flows.

Abstract
INTRODUCTION Laparoscopic left lateral sectionectomy has been proven to be a safe and effective treatment for liver lesions. However, most of the literatures only reported this treatment method on benign lesion or colorectal metastases. The data on long-term outcome of laparoscopic left lateral section resection in patients with HCC and cirrhosis are still limited. The aim of this study is to analyze the survival outcome of laparoscopic left lateral sectionectomy when compared to open approach in patients with HCCs. METHOD Between January 2004 and September 2014, 967 patients had primary HCC with hepatectomy performed. Twenty-four patients had undergone pure laparoscopic left lateral sectionectomy for hepatocellular carcinoma (HCC). Twenty-nine patients with case-matched tumor characteristics and liver functions but received open left lateral sectionectomy for HCC were included for comparison. RESULTS Comparing laparoscopic group to open resection group, the median operation time was 190.5 versus 195 min (P = 0.734); the median blood loss was 100 versus 300 ml (P < 0.001). Hospital stay was 5 days in laparoscopic group versus 6 days in the open group (P = 0.057). There was no difference between the two groups in terms of complications (P = 0.495). The median survival in laparoscopic group was >115 months versus >125 months in the open group (P = 0.853). CONCLUSION Laparoscopic left lateral sectionectomy for HCC is a safe and simple procedure associated with less blood loss. The survival outcome is comparable with conventional open approach. It is becoming a more favorable treatment option even for patients with HCC and cirrhosis.

Abstract
BACKGROUND The predictive value of the Model for End-stage Liver Disease (MELD) for mortality after hepatectomy is unclear. This study aimed to evaluate whether MELD score predicts death after hepatectomy and to identify the most useful score type for predicting mortality. We hypothesized that an increase in this score is correlated with 30-day mortality in patients undergoing hepatic resection. METHODS The American College of Surgeons National Surgical Quality Improvement Program database was queried for hepatectomy. Original MELD, United Network of Organ Sharing-modified MELD (uMELD), integrated MELD (i-MELD), and sodium-corrected MELD (MELD-Na) scores were calculated. Mortality was analyzed by multivariate logistic regression. MELD types were compared using receiver operating characteristic (ROC) curves. RESULTS From 2005 to 2011, 11,933 hepatic resections were performed, including 7,519 partial, 2,104 right, and 1,210 left resections, and 1,100 trisectionectomies. The mean duration of stay was 8.4 ± 22.0 days, and there were 275 deaths (2.4%). The 30-day mortality rates were 1.8%, 6.9%, 15.4%, and 25% according to uMELD strata of 0-9, 10-19, 20-29, and ≥ 30, respectively. Multivariate analysis revealed that increasing MELD stratum was independently associated with higher mortality (P < .001) for all MELD types. The uMELD had the largest effect size (odds ratio [OR], 1.16; 95% CI, 1.10-1.20), whereas i-MELD had the narrowest CI (OR, 1.13; 95% CI, 1.10-1.17) and largest area under the ROC curve. CONCLUSION The postoperative 30-day mortality after hepatectomy increases with increasing MELD score across all MELD types. There is a 16% increase in the odds of mortality for each point increase in uMELD.

Liver resection for hepatocellular carcinoma in 313 Western patients: tumor biology and underlying liver rather than tumor size drive prognosis. J Hepatol 2015; 62:1131-40. [PMID: 25529622 DOI: 10.1016/j.jhep.2014.12.018] [Citation(s) in RCA: 85] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2014] [Revised: 12/08/2014] [Accepted: 12/10/2014] [Indexed: 02/06/2023]
Abstract
BACKGROUND & AIMS Treatment decisions for hepatocellular carcinoma are mostly guided by tumor size. The aim of this study was to analyze resection outcomes according to tumor size and characterize prognostic factors. METHODS Patients resected at a Western center between 1989 and 2010 were grouped by largest tumor size: <50mm, 50-100mm, and >100mm. The primary end points were overall- and recurrence-free survival. Univariate associations with primary endpoints were entered into a Cox proportional hazard regression model. RESULTS Three hundred thirteen patients underwent resection: 111 (36%) had tumors <50mm, 113 (36%) had tumors between 50 and 100mm, and 89 (28%) had tumors >100mm. Five-year overall and disease-free survival rates for the three groups were 67%, 46%, and 34%, and 32%, 27%, and 27%, respectively. Thirty-five patients, mostly from <50mm group, underwent transplantation which was associated with a 91% 5 year survival rate. Tumor size was not an independent predictor of overall or recurrence-free survival on multivariate analyses. Independent predictors of decreased overall survival were: intraoperative transfusion (HR=2.60), cirrhosis (HR=2.42), poorly differentiated tumor (HR=2.04), satellite lesions (HR=1.69), alpha-fetoprotein >200 (HR=1.53), and microvascular invasion (HR=1.48). The use of salvage transplantation was an independent predictor of improved survival (HR=0.21). Recurrence-free survival was predicted by intraoperative transfusion (HR=2.15), poorly differentiated tumor (HR=1.87), microvascular invasion (HR=1.71) and cirrhosis (HR=1.69). CONCLUSION By studying a large group of patients across a distribution of tumor sizes and background liver diseases, it is demonstrated that size alone is a limited prognostic factor. Tumor biology and condition of the underlying liver are better prognosticators and should be given closer attention. Although hampered by recurrence rates, resection is safe and offers good overall survival. In addition, it may allow for better selection for salvage transplantation after consideration of histopathological risk factors.

Abstract
The aims of the current study were to investigate the influence of insufficient radiofrequency ablation (RFA) on the cell proliferation of the human hepatocellular carcinoma (HCC) cells, SMMC7721, and to elucidate the underlying mechanism. SMMC7721 cells were subjected to a 47°C treatment regimen to simulate insufficient RFA, in the presence or absence of KN93 [a specific inhibitor of Ca2+/calmodulin-dependent protein kinase II (CaMKII)], PD98059 [a specific inhibitor of extracellular signal-regulated kinase (ERK)], or axitinib (a specific inhibitor of vascular endothelial growth factor (VEGF) receptor]. Cell proliferation was determined using a thiazolyl terazolium assay (MTT). The levels of CaMKII, phospho-CaMKII, ERK, phospho-ERK and VEGF were observed by western blot analysis. The results demonstrated that the 47°C treatment regimen: i) Triggered upregulation of VEGF expression in the SMMC7721 cells, which was reduced by CaMKII or ERK inhibition; ii) induced ERK activation was prevented by KN93; and iii) promoted SMMC7721 cell proliferation, which was greatly inhibited by axitinib, KN93 and PD98059. In conclusion, the results indicated that insufficient RFA promotes SMMC7721 cell proliferation by activating CaMKII/ERK-dependent VEGF overexpression.

Abstract
Hepatocellular carcinoma represents one of the most challenging frontiers in liver surgery. Surgeons have to face a broad spectrum of aspects, from the underlying liver disease to the new surgical techniques. Safe liver resection can be performed in patients with portal hypertension and well-compensated liver function with a 5-year survival rate of 50%, offering good long-terms results in selected patients. With the advances in laparoscopic surgery, major liver resections can be performed with minimal harm, avoiding the wound and leak complications related to the laparotomies. Studies have shown that oncological margins are the same as in open surgery. In patients submitted to liver resection (either laparoscopic or open) who experience recurrence, re-resection or salvage liver transplantation has been showing to be an alternative approach in well selected cases. The decision making approach to the cirrhotic patient is becoming more complex and should involve hepatologists, liver surgeons, radiologists and oncologists. Better understanding of the different risk factors for recurrence and survival should be aimed in these multidisciplinary discussions. We here in discuss the hot topics related to surgical risk factors regarding the surgical treatment of hepatocellular carcinoma: anatomical resection, margin status, macrovascular tumor invasion, the place of laparoscopy, salvage liver transplantation and liver transplantation.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive tumor that often occurs in the setting of chronic liver disease. Many patients do not initially manifest any symptoms of HCC and present late when cure with surgical resection or transplantation is no longer possible. For this reason, patients at high risk for developing HCC are subjected to frequent screening processes. The surgical management of HCC is complex and requires an inter-disciplinary approach. Hepatic resection is the treatment of choice for HCC in patients without cirrhosis and is indicated in some patients with early cirrhosis (Child-Pugh A). Liver transplantation has emerged in the past decade as the standard of care for patients with cirrhosis and HCC meeting Milan criteria and in select patients with HCC beyond Milan criteria. Loco-regional therapy with transarterial chemoembolization, transarterial embolization, radiofrequency ablation and other similar local treatments can be used as neo-adjuvant therapy to downstage HCC to within Milan criteria or as a bridge to transplantation in patients on transplant wait list.

Abstract
PURPOSE The aim of this study was to evaluate short- and intermediate-term results of laparoscopic liver resection in selected patients with hepatocellular carcinoma (HCC). PATIENTS AND METHODS Eighty-five patients with HCC were subjected to liver resection between February 2007 and January 2013. From these, 30 (35.2%) were subjected to laparoscopic liver resection and were retrospectively analyzed. Special emphasis was given to the indication criteria and to surgical results. RESULTS There were 21 males and 9 females with a mean age of 57.4 years. Patients were subjected to 10 nonanatomic and 20 anatomic resections. Two patients were subjected to hand-assisted procedures (right posterior sectionectomies); all other patients were subjected to totally laparoscopic procedures. Conversion to open surgery was necessary in 4 patients (13.3%). Postoperative complications were observed in 12 patients (40%), and the mortality rate was 3.3%. Mean overall survival was 29.8 months, with 3-year overall and disease-free survival rates of 76% and 58%, respectively. CONCLUSIONS Laparoscopic treatment of selected patients with HCC is safe and feasible and can lead to good short- and intermediate-term results.

Abstract
Purpose Although many patients with hepatocellular carcinoma experience recurrence within 2 years after hepatectomy, some patients with T1 and T2 hepatocellular carcinoma show recurrence-free survival for more than 5 years after surgery. This study was designed to analyze the optimal follow-up period on patients with T1 and T2 hepatocellular carcinoma (HCC) showing recurrence-free survival 5 years after surgery. Methods One hundred seventy patients underwent hepatectomy from January 1995 to December 1999. Numbers of patients with T1 and T2 HCC were 76 and 73, respectively. The recurrence patterns of patients experiencing recurrence more than 5 years after liver resection were analyzed in aspect of clinicopathological features and follow-up period. Results Thirteen patients experienced recurrence more than 5 years after surgery. Only age was found as a significant factor for recurrence. Eight patients were checked regularly with 6-month intervals and the others were checked with 12-month or more intervals. The size of the recurrent tumors in the 6-month interval group had a median of 1.1 cm (range, 1 to 4.2 cm) and the size of the recurrent tumors in the 12-month or more interval group had a median of 3 cm (range, 1.6 to 4 cm). The tumor size was significantly smaller in the 6-month interval group. Conclusion Though the patients with early stage HCC showed high overall survival, some patients experienced a late recurrence of more than 5 years after surgery. Patients less than 60 years old with early stage HCC should be checked regularly with 6-month intervals even over 5 years after liver resection.

Abstract
BACKGROUND Hepatocellular carcinoma is the most common type of primary liver tumor and its incidence is increasing worldwide. The study aimed to compare patients subjected to liver resection or radiofrequency ablation. METHODS One hundred and forty cirrhotic patients in stage A or B of Child-Pugh with single nodular or multinodular hepatocellular carcinoma were included in this retrospective study. Among them, 87 underwent surgical resection, and 53 underwent percutaneous radiofrequency ablation. Patient characteristics, survival, and recurrence-free survival were analyzed. RESULTS Recurrence-free survival was longer in the resection group in comparison to the radiofrequency group with a median recurrence-free time of 36 versus 26 months, respectively (P=0.01, HR=1.52, 95% CI: 1.05-2.25). In the resection group, median survival was 46 months, with the 1-, 3- and 5-year survival rates of 89.7%, 72.4% and 40.2%. In the radiofrequency group, median survival was 32 months, with the 1-, 3- and 5-year survival rates of 83.0%, 43.4% and 22.6% (P<0.01). CONCLUSIONS Surgical resection improves the overall survival and recurrence-free survival in comparison with radiofrequency ablation. New evidences are needed to define the real role of the percutaneous technique as an alternative to surgery.

Abstract
PURPOSE To validate the 2010 diagnostic criteria from the American Association for the Study of Liver Diseases (AASLD) for hepatocellular carcinoma (HCC) on MRI using the surgical liver specimen as a gold standard. PATIENTS AND METHODS A total of 21 liver transplant recipients were retrospectively included. Each underwent surgery because of HCC between January 2007 and January 2008. Pre-transplant MRI was performed on a 1.5 Tesla MR unit. The T1W and T2W signal and kinetic contrast enhancement were correlated for each lesion with the surgical specimen. Lesion diameters between MRI and specimen were compared (Spearman). A multivariate model was created (R statistics software package) to predict the presence and grade of tumor differentiation (WHO, Edmonson Steiner). RESULTS A total of 71 nodules were detected at histology, including 54 HCC (mean size: 25.3mm) compared to 68 on MRI. There was moderate agreement (r=0.58, P<0.001) between the maximum lesion diameters measured on MRI and at histology. Wash-out on MRI provided an accuracy of 75 % for the detection of HCC (sensitivity=75 %, specificity=76 %). Adding T2W hyperintensity to the AASLD criteria increased the sensitivity of MRI from 70.3 % to 77.7 % for the diagnosis of HCC and from 67.6 % to 79 % for nodules less than 20mm in diameter, without affecting specificity. On multivariate analysis, wash out as a single variable was significantly associated with a diagnosis of HCC (P<0.01, odds ratio 12.0, CI 95 % [2.6-55.5]). T1W hyperintensity (P=0.04, odds ratio 5.4) and loss of signal on opposed-phase images (P=0.02, odds ratio 9.2) were predictive of good differentiation. CONCLUSION On MRI, the AASLD criteria or presence of wash out within a liver nodule in patients with underlying chronic hepatocellular disease are suggestive of tumoral transformation. The addition of T2W hyperintensity to the AASLD criteria increases the detection of HCC, especially nodules smaller than 20mm.

Abstract
Liver resection remains the standard therapy for solitary hepatocellular carcinoma in patients with preserved hepatic function. In well-selected patients, 5-year survival rates are good and can approach that of liver transplantation for early-stage disease. Patient selection is critical to optimizing therapeutic benefit, and the health of the native liver must be considered in addition to tumor characteristics. Hepatic recurrence after resection is common. The difficulty lies in deciding which patients with chronic liver disease and small solitary tumors are best served by resection and which should proceed with transplant evaluation; this is the focus of this article.

Abstract
The role of hepatic resection, taking into consideration the functional status of the liver, for localized hepatocellular carcinoma (HCC) is an established curative treatment. In advance disease, a variety of interventional-based liver-directed therapies and more recently systemic therapy with sorafenib are available to treat unresectable tumors. Extrahepatic Metastasis (EHM) of HCC may occur at initial diagnosis or during recurrence following treatment. This may occur with or without concurrent intrahepatic disease. We reviewed the published works on surgical metastasectomy for common sites of EHM of HCC metastases. It appears from the studies reported in the literature that from selected cases reported, long-term survival may be achieved from resecting metastasis at sites of the abdominal lymph node, adrenal gland, lung, and peritoneum. The encouraging results presented demonstrate that highly selected fit patients may be suitable candidates for these radical curative pursuits. It is likely that indications for resection of EHM HCC may benefit patients with limited isolated metastasis, who have a preserved liver function, and whose primary tumor has been adequately controlled. A registry study to pull the results of case reports and institutional experiences may be useful in cumulating evidence of this practice.

Abstract
As the number of effective treatment options has increased, the management of patients with hepatocellular carcinoma has become complex. The most appropriate therapy depends largely on the functional status of the underlying liver. In patients with advanced cirrhosis and tumor extent within the Milan criteria, liver transplantation is clearly the best option, as this therapy treats the cancer along with the underlying hepatic parenchymal disease. As the results of transplantation has become established in patients with limited disease, investigation has increasingly focused on downstaging patients with disease outside of Milan criteria and defining the upper limits of transplantable tumors. In patients with well preserved hepatic function, liver resection is the most appropriate and effective treatment. Hepatic resection is not as constrained by tumor extent and location to the same degree as transplantation and ablative therapies. Some patients who recur after resection may still be eligible for transplantation. Ablative therapies, particularly percutaneous radiofrequency ablation and transarterial chemoembolization have been used primarily to treat patients with low volume irresectable tumors. Whether ablation of small tumors provides long term disease control that is comparable to resection remains unclear.

Abstract
BACKGROUND Some series have suggested that laparoscopy is beneficial for resection of hepatocellular carcinoma. This has to be confirmed in larger series. The aim of this study was to analyze the results of 3 European surgical centers on laparoscopic liver resections for hepatocellular carcinoma. STUDY DESIGN Prospective databases of 3 European centers involved in the development of laparoscopic liver surgery were combined. Between 1998 and 2008, 163 liver resections for hepatocellular carcinoma were performed. Liver parenchyma was cirrhotic in 120 (73.6%) patients. Liver resection was anatomic in 107 (65.6%) patients and was a major resection (>or=3 segments) in 16 (9.8%). A totally laparoscopic approach was used in 155 (95.1%) patients. RESULTS Median surgical duration was 180 minutes. Median operative blood loss was 250 mL, and 16 (9.8%) patients received blood transfusion. Conversion to open surgery was required in 15 (9.2%) patients. Median tumor size was 3.6 cm and median surgical margin was 12 mm. Liver-specific and general complications occurred in 19 (11.6%) and 17 (10.4%) patients, respectively. Hospital length of stay was 7 days. A further analysis of early (n = 75) and recent (n = 88) experiences showed improved results in the latter group. Overall and recurrence-free survival rates at 1, 3, and 5 years were 92.6%, 68.7%, 64.9%, and 77.5%, 47.1%, 32.2%, respectively. CONCLUSIONS This study demonstrates that laparoscopic resection for hepatocellular carcinoma is feasible in selected patients, with good operative and oncologic results. Laparoscopy should be routinely considered in centers experienced in liver surgery and advanced laparoscopy.

Abstract
Background The objective of this work is to evaluate a new concept of intraoperative three-dimensional (3D) visualization system to support hepatectomy. The Resection Map aims to provide accurate cartography for surgeons, who can therefore anticipate risks, increase their confidence and achieve safer liver resection. Methods In an experimental prospective cohort study, ten consecutive patients admitted for hepatectomy to three European hospitals were selected. Liver structures (portal veins, hepatic veins, tumours and parenchyma) were segmented from a recent computed tomography (CT) study of each patient. The surgeon planned the resection preoperatively and read the Resection Map as reference guidance during the procedure. Objective (amount of bleeding, tumour resection margin and operating time) and subjective parameters were retrieved after each case. Results Three different surgeons operated on seven patients with the navigation aid of the Resection Map. Veins displayed in the Resection Map were identified during the surgical procedure in 70.1% of cases, depending mainly on size. Surgeons were able to track resection progress and experienced improved orientation and increased confidence during the procedure. Conclusions The Resection Map is a pragmatic solution to enhance the orientation and confidence of the surgeon. Further studies are needed to demonstrate improvement in patient safety.

Abstract
BACKGROUND/PURPOSE Liver transplantation (LT) is the best theoretical treatment of hepatocellular carcinoma (HCC) fulfilling the Milan criteria (TNM stages 1-2). However, LT is limited by organ availability and tumor progression on the waiting list. Liver resection (LR) may represent an alternative in these patients. The aim of this study is to report the results of LR in transplantable patients. PATIENTS From 1990 to 2007, 274 patients underwent liver resection for HCC. Sixty-seven (24%) met the Milan criteria on pathologic study of the specimen. Ten were TNM stage 1 and 57 stage 2 and all had chronic liver disease. There were 56 men and 11 women with a mean age of 63. LR included 12 major hepatectomies, 14 bisegmentectomies, 14 segmentectomies, and 27 nonanatomic resections. Thirty-seven resections were performed through a laparoscopic approach and there were only 8 open resections since 1998. RESULTS Three patients died postoperatively (4.5%), none after laparoscopic resection. Morbidity rate was 34%. After a mean follow-up of 4.8 years, 36 patients (54%) developed intrahepatic tumor recurrence. Twenty-eight (77%) were again transplantable of which 16 (44%) were transplanted. Two additional patients underwent pre-emptive LT (ie before recurrence). When considering 44 patients <65 years at the time of resection (ie upper age limit for LT), the rates of recurrence, transplantable recurrence, and intention to treat salvage transplantation (patients with transplantable recurrence actually transplanted) were 59%, 80%, and 61%, respectively. Overall and disease free 5-year survival rates were 72% and 44%, respectively. Survival was not influenced by TNM stage 1 or 2, AFP level, tumor differentiation, or the presence microscopic vascular invasion. Survival after salvage LT was 70% and 87% when calculated from the date of LT and LR, respectively. CONCLUSION LR for small solitary HCC in compensated cirrhosis yields an overall survival rate comparable to upfront LT. Despite a significant recurrence rate, close imaging monitoring after resection allows salvage LT in 61% of patients with recurrence on intention to treat analysis.

Abstract
INTRODUÇÃO: As ressecções hepáticas representam umas das últimas fronteiras vencidas pela cirurgia videolaparoscópica. Apesar da complexidade do procedimento, da demanda de grande incorporação de tecnologia e necessidade de experiência em cirurgia hepática e laparoscópica, a indicação do método tem crescido de forma expressiva nos últimos anos. OBJETIVO: Realizar análise crítica do método, baseada nos trabalhos existentes na literatura, ressaltando o estado atual de suas indicações, exequibilidade, segurança, resultados e aspectos técnicos primordiais. MÉTODO: Foram identificados e analisados os trabalhos pertinentes nas bases de dados LILACS e PUBMED até dezembro de 2009, utilizando-se os descritores "liver resection", "laparoscopic" e "liver surgery". Não foram encontrados trabalhos prospectivos e randomizados sobre o tema, sendo os dados disponíveis provenientes de série de casos, estudos caso-controle e alguns estudos multicêntricos e metanálises. CONCLUSÃO: A hepatectomia por videolaparoscopia é hoje operação segura e factível, mesmo para as ressecções hepáticas maiores, com baixo índice de morbimortalidade. O método pode ser utilizado para lesões malignas sem prejuízo dos princípios oncológicos e com vantagens nos pacientes com cirrose ou disfunção hepática. A melhor indicação recai sobre as lesões benignas, em especial o adenoma hepatocelular. Em mãos experientes e casos selecionados, como as lesões benignas localizadas nos segmentos anterolaterais hepáticos, principalmente no segmento lateral esquerdo, a ressecção videolaparoscópica pode ser considerada hoje como tratamento padrão.

Abstract
BACKGROUND Utilizing laparoscopy for major surgeries such as hepatectomy is a relatively new concept. Initially, benign pathologies dominated indications for resection. Our experience in an Australian setting with primarily malignant diagnoses is described. METHODS A review of patients' profiles, pathology, surgery and outcome was performed on 35 patients between December 2005 and August 2008. Data were collected and analysed retrospectively from medical records on a pre-designed datasheet. RESULTS Commonest indication for resection was colorectal metastasis (54%), 71% of all resections were for malignancy. Average operating time was 2 h 31 min (range 30 min-7 h, 15 min). Major morbidity consisted of one bile leak, two subphrenic abscesses and one pulmonary embolus. There were no deaths. Conversion to open was required in 20% and two patients required intra-operative blood transfusions. Average length of stay overall was 6.1 days (range 1-27), but as low as 2 days for some left lateral sectionectomies. Cessation of parenteral analgesia, return to normal diet and full mobility were achieved on average at 2.4, 2.3 and 2.8 days. Significant post-operative liver dysfunction was seen in two patients, which returned to normal by discharge. One patient died of disease progression 4 months after surgery. There were two involved margins in 35 patients (6%). CONCLUSIONS Laparoscopic hepatectomy is a developing and safe technique in a select group of patients including those with malignancies, resulting in short hospital stays, rapid return to normal diet, full mobility and minimal morbidity with acceptable oncological parameters. This study is not comparative in nature, but provides evidence to support further investigation and establishment of this new technique for liver resection.
