| 2 | Combined resection and radiofrequency ablation for multifocal hepatocellular carcinoma: Prognosis and outcomes显示文摘AIM: To analyze the combined treatment of resection and intraoperative radiofrequency ablation (RFA) for multifocal hepatocellular carcinoma in terms of prognosis and surgical outcomes.METHODS: This study was a retrospective case comparison study using prospectively collected data. The study covered the period from April 2001 to December 2006. The data of 200 patients with histologically confirmed hepatocellular carcinoma were reviewed. Nineteen patients (17 men and 2 women) having received resection in combination with RFA were chosen as subjects of the study (the combination group). Fiftyfour patients (43 men and 11 women) having received resection alone were selected for comparison (the resection group). The two groups matched tumor number and tumor size, and all the patients in the two groups displayed no tumor rupture, major vascular involvement and distant metastasis. Their demographics, preoperative assessment, disease recurrence patterns, overall survival and diseasefree survival were compared.RESULTS: In the combination group, the medianage was 65 years (range, 3477 years), the median tumor number was 3 (range, 29), and the median tumor size was 6 cm (range, 1.214 cm). In the resection group, the median age was 51.5 years (range, 2780 years, P = 0.003), the median tumor number was 3 (range, 29, P = 0.574), and the median tumor size was 6 cm (range, 114 cm, P = 0.782). The two groups were similar in characteristics of tumors and comorbidities, and had comparable results in preoperative liver function tests. All patients had ChildPugh class A status. Bilobar involvement occurred in 14 patients (73.6%) in the combination group and 3 patients (5.5%) in the resection group (P = 0.04). Six patients (32%) in the combination group and 35 patients (65%) in the resection group underwent major hepatectomy. Thirteen patients (68%) in the combination group and 19 patients (35%) in the resection group underwent minor hepatectomy (P = 0.012). The combination group had fewer major resections (32% vs 65%, P = 0.012), less blood loss (400 vs 657 mL, P = 0.007), shorter operation time (270 vs 400 min, P = 0.001), and shorter hospital stay (7 vs 8.5 d, P = 0.042). The two groups displayed no major differences in surgical complications (15.8% vs 31.5%, P = 0.24), disease recurrence (63.2% vs 50%, P = 0.673), hospital mortality (5.3% vs 5.6%, P = 1), and overall survival (53 vs 44.5 mo, P = 0.496).CONCLUSION: Safe and effective for selected patients with multifocal hepatocellular carcinoma, the combination of resection and intraoperative RFA widens the applicability of surgical intervention for the disease. | Tan To Cheung Kelvin K Ng Kenneth S Chok See Ching Chan Ronnie T Poon Chung Mau Lo Sheung Tat Fan | 2010 | World Journal of Gastroenterology2010，16，24： | 14 |

| 5 | Acute liver injury induced by weight-loss herbal supplements显示文摘We report three cases of patients with acute liver injury induced by weight-loss herbal supplements. One patient took Hydroxycut while the other two took Herbalife supplements. Liver biopsies for all patients dem onstrated f indings consistent with drug-induced acute liver injury. To our knowledge, we are the fi rst instit ute to report acute liver injury from both of these two typ es of weight-loss herbal supplements together as a case series. The series emphasizes the importance of taking a cautious approach when consuming herbal supp lements for the purpose of weight loss. | Gary C Chen Vivek S Ramanathan David Law Pauline Funchain George C Chen Samuel French Boris Shlopov Viktor Eysselein David Chung Sonya Reicher Binh V Pham | 2010 | World Journal of Hepatology2010，2，11： | 5 |
| 6 | Features of extrahepatic metastasis after radiofrequency ablation for hepatocellular carcinoma显示文摘BACKGROUND Extrahepatic metastasis(EHM)of hepatocellular carcinoma(HCC)is associated with poor outcomes.However,the clinical features and risk factors of EHM of HCC after radiofrequency ablation(RFA)remain unclear.AIM To elucidate the characteristics and risk factors of EHM after RFA for HCC.METHODS From January 2008 to December 2017,we retrospectively enrolled 661 patients who underwent RFA as first-line treatment for HCC at 2 tertiary hospitals.The inclusion criteria were age≥18 years,a diagnosis of HCC,and treatment-naivety.Abdominal computed tomography(CT)or magnetic resonance imaging(MRI)and alpha-fetoprotein measurements were routinely performed at 1 mo after RFA and followed-up at intervals of 3-6 mo.Univariate analyses were performed using the chi-squared test or Student’s t-test,and univariate and multivariate analyses were performed via logistic regression,as appropriate.RESULTS EHM was diagnosed in 44 patients(6.7%)during a median follow-up period of 1204 days.The 10-year cumulative rate of HCC recurrence and EHM was 92.7%and 33.7%,respectively.Initial recurrence was most often intrahepatic,and the rate of extrahepatic recurrence at initial recurrence was only 1.2%.The median time to the diagnosis of EHM was 2.68 years,and 68.2%of patients developed EHM within 2 years of the first recurrence,regardless of recurrence-free survival and 75.0%of patients developed EHM within 5 years after first recurrence.EHM was mostly diagnosed via abdominal CT/MRI in 33(75.0%)and 38 of 44 patients(86.4%)with EHM had either positive abdominal CT scan results or serum AFP level elevation.In multivariate analysis,recurrence-free survival<2 years,ablation zone/tumor size<2,and alpha-fetoprotein level>400 IU/mL were associated with a high EHM risk.CONCLUSION EHM occurs following multiple intrahepatic recurrences after RFA and combined contrast-enhanced abdominal CT and serum AFP were useful for surveillance.Patients especially with high-risk factors require close follow-up for EHM. | Jae H Yoon Young J Goo Chae-Jun Lim Sung K Choi Sung B Cho Sang S Shin Chung H Jun | 2020 | World Journal of Gastroenterology2020，26，32： | 3 |

| 8 | Parvovirus B19 induced hepatic failure in an adult requiring liver transplantation显示文摘Parvovirus B19 induced acute hepatitis and hepatic failure have been previously reported, mainly in children. Very few cases of parvovirus induced hepatic failure have been reported in adults and fewer still have required liver transplantation. We report the case of a 55-year-old immunocompetent woman who developed fulminant hepatic failure after acute infection with Parvovirus B19 who subsequently underwent orthotopic liver transplantation. This is believed to be the first reported case in the literature in which an adult patient with fulminant hepatic failure associated with acute parvovirus B19 infection and without hematologic abnormalities has been identified prior to undergoing liver transplantation. This case suggests that Parvovirus B19 induced liver disease can affect adults, can occur in the absence of hematologic abnormalities and can be severe enough to require liver transplantation. | Darin S Krygier Urs P Steinbrecher Martin Petric Siegfried R Erb Stephen W Chung Charles H Scudamore Andrzej K Buczkowski Eric M Yoshida | 2009 | World Journal of Gastroenterology2009，15，32： | 3 |

| 10 | Clinical outcomes in patients with ICU-related pancreatitis显示文摘AIM:To identify risk factors predictive of intensive care unit(ICU) mortality in patients with ventilator-related pancreatitis.The clinical outcomes of patients with ventilator-related pancreatitis were compared with those of patients with pancreatitis-related respiratory failure as well as controls.METHODS:One hundred and forty-eight patients with respiratory failure requiring mechanical ventilation and concomitant acute pancreatitis were identified from a prospectively collected dataset of 9108 consecutive patients admitted with respiratory failure over a period of five years.Sixty patients met the criteria for ventilator-related pancreatitis,and 88(control patients),for pancreatitis-related respiratory failure.RESULTS:Mortality rate in ventilator-related pancreatitis was comparable to that in ICU patients without pancreatitis by case-control methodology(P=0.544).Multivariate logistic regression analysis identified low PaO2/FiO2(OR:1.032,95% CI:1.006-1.059,P=0.016) as an independent risk factor for mortality in patients with ventilator-related pancreatitis.The mortality rate in patients with ventilator-related pancreatitis was lower than that in patients with acute pancreatitis-related respiratory failure(P<0.001).CONCLUSION:We found that low PaO2/FiO2 was an independent clinical parameter predictive of ICU mortality in patients with ventilator-related pancreatitis. | Chia-Cheng Tseng Wen-Feng Fang Yu-Hsiu Chung Yi-Hsi Wang Ivor S Douglas Meng-Chih Lin | 2009 | World Journal of Gastroenterology2009，15，39： | 3 |
| 11 | Statistical issues and approaches in endophenotype research显示文摘The endophenotype concept was initially proposed to enhance the power of genetic studies of complex disorders. It is closely related to the genetic component in a liability-threshold model; a perfect endophenotype should have a correlation of 1 with the genetic component of the liability to disease. In reality, a putative endophenotype is unlikely to be a perfect representation of the genetic component of disease liability. The magnitude of the correlation between a putative endophenotype and the genetic component of disease liability can be estimated by fitting multivariate genetic models to twin data. A number of statistical methods have been developed for incorporating endophenotypes in genetic linkage and association analyses with the aim of improving statistical power. The most recent of such methods can handle multiple endophenotypes simultaneously for the greatest increase in power. In addition to increasing statistical power, endophenotype research plays an important role in helping to understand the mechanisms which connect the associated genetic variants with disease occurrence. Novel statistical approaches may be required for the analysis of the complex relationships between endophenotypes at different levels and how they converge to cause the occurrence of disease. | SHAM Pak Chung CHERNY Stacey S HALL Mei-Hua | 2011 | Chinese Science Bulletin2011，56，32： | 2 |

| 20 | Strategies to tackle the challenges of external beam radiotherapy for liver tumors显示文摘Primary and metastatic liver cancer is an increasingly common and difficult to control disease entity.Radiation offers a non-invasive treatment alternative for these patients who often have few options and a poor prognosis.However,the anatomy and aggressiveness of liver cancer poses significant challenges such as accurate localization at simulation and treatment,management of motion and appropriate selection of dose regimen.This article aims to review the options available and provide information for the practical implementation and/or improvement of liver cancer radiation programs within the context of stereotactic body radiotherapy and image-guided radiotherapy guidelines.Specific patient inclusion and exclusion criteria are presented given the significant toxicity found in certain sub-populations treated with radiation.Indeed,certain sub-populations,such as those with tumor thrombosis or those with larger lesions treated with transarterial chemoembolization,have been shown to have significant improvements in outcome with the addition of radiation and merit special consideration.Implementing a liver radiation programrequires three primary challenges to be addressed:(1) immobilization and motion management;(2) localization;and(3) dose regimen and constraint selection.Strategies to deal with motion include simple internal target volume(ITV) expansions,non-gated ITV reduction strategies,breath hold methods,and surrogate marker methods to enable gating or tracking.Localization of the tumor and organs-at-risk are addressed using contrast infusion techniques to take advantage of different normal liver and cancer vascular anatomy,imaging modalities,and margin management.Finally,a dose response has been demonstrated and dose regimens appear to be converging.A more uniform approach to treatment in terms of technique,dose selection and patient selection will allow us to study liver radiation in larger and,hopefully,multicenter randomized studies. | Michael I Lock Jonathan Klein Hans T Chung Joseph M Herman Edward Y Kim William Small Nina A Mayr Simon S Lo | 2017 | World Journal of Hepatology2017，9，14： | 2 |
