3Efficacy of transcatheter embolization/chemoembolization (TAE/TACE) for the treatment of single hepatocellular carcinoma显示文摘AIM:To investigate the efficacy of transcatheter embolization/chemoembolization (TAE/TACE) in cirrhotic patients with single hepatocellular carcinoma (HCC) not suitable for surgical resection and percutaneous ablation therapy. METHODS:A cohort of 176 consecutive cirrhotic patients with single HCC undergoing TAE/TACE was reviewed; 162 patients had at least one image examination (helical CT scan or triphasic contrastenhanced MRI) after treatment and were included into the study. TAE was performed with Lipiodol followed by Gelfoam embolization; TACE was performed with Farmorubicin prepared in sterile drip at a dose of 50 mg/m2,infused over 30 min using a peristaltic pump,and followed by Lipiodol and Gelfoam embolization. RESULTS:Patients characteristics were:mean age,62 years; male/female 117/45; Child-Pugh score 6.2 ± 1.1; MELD 8.7 ± 2.3; mean HCC size,3.6 (range 1.0-12.0) cm. HCC size class was ≤ 2.0 cm,n = 51; 2.1-3.0 cm,n = 35; 3.1-4.0 cm,n = 29; 4.1-5.0 cm,n = 22; 5.1-6.0 cm,n = 11; and > 6.0 cm,n = 14. Patients received a total of 368 TAE/TACE (mean 2.4 ± 1.7). Complete tumor necrosis was obtained in 94 patients (58%),massive (90%-99%) necrosis in 16 patients (10%),partial (50%-89%) necrosis in 18 patients (11%) and poor (< 50%) necrosis in the remaining 34 patients (21%). The rate of complete necrosis according to the HCC size class was:69%,69%,52%,68%,50% and,13% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. Kaplan-Mayer survival at 24-mo was 88%,68%,59%,59%,45%,and 53% for lesions of ≤ 2.0,2.1-3.0,3.1-4.0,4.1-5.0,5.1-6.0,and > 6.0 cm,respectively. CONCLUSION:Our study showed that in cirrhotic patients with single HCC smaller than 6.0 cm,TAE/TACE produces complete local control of tumor in a significant proportion of patients. TAE/TACE is an effective therapeutic option in patients with single HCC not suitable for surgical resection or percutaneous ablation therapies. Further studies should investigate if the new available embolization agents or drug eluting beads may improve the effect on tumor necrosis.Roberto Miraglia Giada Pietrosi Luigi Maruzzelli Ioannis Petridis Settimo Caruso Gianluca Marrone Giuseppe Mamone Giovanni Vizzini Angelo Luca Bruno Gridelli 2007World Journal of Gastroenterology2007,13,21:38
4Follow-up of intestinal metaplasia in the stomach: When, how and why显示文摘Gastric cancer remains the second most frequent cause of cancer-related mortality in the world. Screening programs in some Asian countries are impractical in the majority of other countries worldwide. Therefore, follow-up of precancerous lesions is advisable for secondary gastric cancer prevention. Intestinal metaplasia (IM) is recognized as a precancerous lesion for gastric cancer, increasing the risk by 6-fold. IM is highly prevalent in the general population, being detected in nearly 1 of every 4 patients undergoing upper endoscopy. The IM prevalence rate is significantly higher in patients with Helicobacter pylori (H. pylori) infection, in first-degree relatives of gastric cancer patients, in smokers and it increases with patient age. IM is the 'breaking point' in the gastric carcinogenesis cascade and does not appear to regress following H. pylori eradication, although the cure of infection may slow its progression. Gastric cancer risk is higher in patients with incomplete-type IM, in those with both antral and gastric body involvement, and the risk significantly increases with IM extension over 20% of the gastric mucosa. Scheduled endoscopic control could be cost-effective in IM patients, depending on the yearly incidence of gastric cancer in IM patients, the stage of gastric cancer at diagnosis discovered at surveillance, and the cost of endoscopy. As a pragmatic behavior, yearly endoscopic control would appear justified in all IM patients with at least one of these conditions: (1) IM extension > 20%; (2) the presence of incomplete type IM; (3) first-degree relative of gastric cancer patients; and (4) smokers. In the remaining IM patients, a less intensive (2-3 years) could be proposed.Angelo Zullo Cesare Hassan Adriana Romiti Michela Giusto Carmine Guerriero Roberto Lorenzetti Salvatore MA Campo Silverio Tomao 2012World Journal of Gastrointestinal Oncology2012,4,3:25

6乳腺癌内分泌治疗专家共识与争议显示文摘2013年4月,上海举行“乳腺癌内分泌治疗高峰论坛”专家讨论环节,与会的400名乳腺癌专业医师就目前乳腺癌内分泌治疗若干热点问题投票表决,文中问题后具体选项所列百分比为现场投票结果。讨论由江泽飞教授主持,徐兵河、邵志敏、沈镇宙、杨名添、王永胜、刘荫华、段学宁、胡夕春教授和来自意大利的Angelo DiLeo教授作为特邀点评嘉宾,共同讨论了与乳腺癌内分泌治疗热点问题相关的循证医学证据和表决结果,现整理如下,供各位同道参考。1绝经后激素受体阳性乳腺癌术后辅助治疗的选择?江泽飞 徐兵河 邵志敏 沈镇宙 杨名添 王永胜 刘荫华 段学宁 胡夕春 Angelo DiLeo 2013中国癌症杂志2013,23,9:22
7Exploring the metabolic syndrome: Nonalcoholic fatty pancreas disease显示文摘After the first description of fatty pancreas in 1933,the effects of pancreatic steatosis have been poorly investigated,compared with that of the liver. However,the interest of research is increasing. Fat accumulation,associated with obesity and the metabolic syndrome(Met S),has been defined as 'fatty infiltration' or 'nonalcoholic fatty pancreas disease'(NAFPD). The term 'fatty replacement' describes a distinct phenomenon characterized by death of acinar cells and replacement by adipose tissue. Risk factors for developing NAFPD include obesity,increasing age,male sex,hypertension,dyslipidemia,alcohol and hyperferritinemia. Increasing evidence support the role of pancreatic fat in the development of type 2 diabetes mellitus,Met S,atherosclerosis,severe acute pancreatitis and even pancreatic cancer. Evidence exists that fatty pancreas could be used as the initial indicator of 'ectopic fat deposition',which is a key element of nonalcoholic fatty liver disease and/or Met S. Moreover,in patients with fatty pancreas,pancreaticoduodenectomy is associated with an increased risk of intraoperative blood loss and post-operative pancreatic fistula.Roberto Catanzaro Biagio Cuffari Angelo Italia Francesco Marotta 2016World Journal of Gastroenterology2016,22,34:22
8Gastric low-grade mucosal-associated lymphoid tissue-lymphoma: Helicobacter pylori and beyond显示文摘The stomach is the most frequently involved site for extranodal lymphomas,accounting for nearly two-thirds of all gastrointestinal cases.It is widely accepted that gastric B-cell,low-grade mucosal-associated lymphoid tissue(MALT)-lymphoma is caused by Helicobacter pylori(H.pylori)infection.MALT-lymphomas may engender different clinical and endoscopic patterns.Often,diagnosis is confirmed in patients with only vague dyspeptic symptoms and without macroscopic lesions on gastric mucosa.H.pylori eradication leads to lymphoma remission in a large number of patients when treatment occurs at an early stage(Ⅰ-Ⅱ1).Neoplasia confined to the submucosa,localized in the antral region of the stomach,and without API2-MALT1 translocation,shows a high probability of remission following H.pylori eradication.When both bacterial infection and lymphoma recur,further eradication therapy is generally effective.Radiotherapy,chemotherapy and,in selected cases,surgery are the available therapeutic options with a high success rate for those patients who fail to achieve remission,while data on immunotherapy with monoclonal antibodies (rituximab)are still scarce.The 5-year survival rate is higher than 90%,but careful,long-term follow-up is required in these patients since lymphoma recurrence has been reported in some cases.Angelo Zullo Cesare Hassan Francesca Cristofari Francesco Perri Sergio Morini 2010World Journal of Gastrointestinal Oncology2010,2,4:21
9Splanchnic vasodilation and hyperdynamic circulatory syndrome in cirrhosis显示文摘Portal hypertension is a clinical syndrome which leads to several clinical complications,such as the formation and rupture of esophageal and/or gastric varices,ascites,hepatic encephalopathy and hepato-renal syndrome.In cirrhosis,the primary cause of the increase in portal pressure is the enhanced resistance to portal outflow.However,also an increase in splanchnic blood flow worsens and maintains portal hypertension.The vasodilatation of arterial splanchnic vessels and the opening of collateral circulation are the determinants of the increased splanchnic blood flow.Several vasoactive systems/substances,such as nitric oxide,cyclooxygenase-derivatives,carbon monoxide and endogenous cannabinoids are activated in portal hypertension and are responsible for the marked splanchnic vasodilatation.Moreover,an impaired reactivity to vasoconstrictor systems,such as the sympathetic nervous system,vasopressin,angiotensinⅡand endothelin-1,plays a role in this process.The opening of collateral circulation occurs through the reperfusion and dilatation of preexisting vessels,but also through the generation of new vessels.Splanchnic vasodilatation leads to the onset of the hyperdynamic circulatory syndrome,a syndrome which occurs in pa-tients with portal hypertension and is characterized by increased cardiac output and heart rate,and decreased systemic vascular resistance with low arterial blood pressure.Understanding the pathophysiology of splanchnic vasodilatation and hyperdynamic circulatory syndrome is mandatory for the prevention and treatment of portal hypertension and its severe complications.Massimo Bolognesi Marco Di Pascoli Alberto Verardo Angelo Gatta 2014World Journal of Gastroenterology2014,20,10:21
10Histopathology of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is currently the sixth most common type of cancer with a high mortality rate and an increasing incidence worldwide.Its etiology is usually linked to environmental,dietary or lifestyle factors.HCC most commonly arises in a cirrhotic liver but interestingly an increasing proportion of HCCs develop in the non-fibrotic or minimal fibrotic liver and a shift in the underlying etiology can be observed.Although this process is yet to be completely understood,this changing scenario also has impact on the material seen by pathologists,presenting them with new diagnostic dilemmas.Histopathologic criteria for diagnosing classical,progressed HCC are well established and known,but with an increase in detection of small and early HCCs due to routine screening programs,the diagnosis of these small lesions in core needle biopsies poses a difficult challenge.These lesions can be far more difficult to distinguish from one another than progressed HCC,which is usually a clear cut hematoxylin and eosin diagnosis.Furthermore lesions thought to derive from progenitor cells have recently been reclassified in the WHO.This review summarizes recent developments and tries to put new HCC biomarkers in context with the WHOs reclassification.Furthermore it also addresses the group of tumors known as combined hepatocellular-cholangiocellular carcinomas.Manuel Schlageter Luigi Maria Terracciano Salvatore D'Angelo Paolo Sorrentino 2014World Journal of Gastroenterology2014,20,43:20
11Management of duodenal stump fistula after gastrectomy for gastric cancer: Systematic review显示文摘AIM: To identify the most effective treatment of duodenalstump fistula(DSF) after gastrectomy for gastric cancer.METHODS: A systematic review of the literature was performed. Pub Med, EMBASE, Cochrane Library, CILEA Archive, BMJ Clinical Evidence and Up To Date databases were analyzed. Three hundred eighty-eight manuscripts were retrieved and analyzed and thirteen studies published between 1988 and 2014 were finally selected according to the inclusion criteria, for a total of 145 cases of DSF, which represented our group of study. Only patients with DSF after gastrectomy for malignancy were selected. Data about patients' characteristics, type of treatment, short and long-term outcomes were extracted and analyzed. RESULTS: In the 13 studies different types of treatment were proposed: conservative approach, surgical approach, percutaneous approach and endoscopic approach(3 cases). The overall mortality rate was 11.7% for the entire cohort. The more frequent complications were sepsis, abscesses, peritonitis, bleeding, pneumonia and multi-organ failure. Conservative approach was performed in 6 studies for a total of 79 patients, in patients with stable general condition, often associated with percutaneous approach. A complete resolution of the leakage was achieved in 92.3% of these patients, with a healing time ranging from 17 to 71 d. Surgical approach included duodenostomy, duodenojejunostomy, pancreatoduodenectomy and the use of rectus muscle flap. In-hospital stay of patients who underwent relaparotomy ranged from 1 to 1035 d. The percutaneous approach included drainage of abscesses or duodenostomy(32 cases) and percutaneous biliary diversion(13 cases). The median healing time in this group was 43 d. CONCLUSION: Conservative approach is the treatment of choice, eventually associated with percutaneus drainage. Surgical approach should be reserved for severe cases or when conservative approaches fail.Paolo Aurello Dario Sirimarco Paolo Magistri NiccolòPetrucciani Giammauro Berardi Silvia Amato Marcello Gasparrini Francesco D’Angelo Giuseppe Nigri Giovanni Ramacciato 2015World Journal of Gastroenterology2015,21,24:19
12A randomized double-blind trial on perioperative administration of probiotics in colorectal cancer patients显示文摘AIM:To investigate whether probiotic bacteria,given perioperatively,might adhere to the colonic mucosa, reduce concentration of pathogens in stools,and modulate the local immune function. METHODS:A randomized,double-blind clinical trial was carried out in 31 subjects undergoing elective colorectal resection for cancer.Patients were allocated to receive either a placebo(group A,n=10),or a dose of 10 7 of a mixture of Bifidobacterium longum(BB536) and Lactobacillus johnsonii(La1)(group B,n=11),or the same mixture at a concentration of 10 9 (group C,n=10).Probiotics,or a placebo,were given orally 2 doses/d for 3 d before operation.The same treatment continued postoperatively from day two to day four. Stools were collected before treatment,during surgery (day 0)and 5 d after operation.During the operation, colonic mucosa samples were harvested to evaluate bacterial adherence and to assess the phenotype of dendritic cells(DCs)and lymphocyte subsets by surface antigen expression(flow cytometry).The presence of BB536 and La1 was evaluated by the random amplified polymorphism DNA method with specific polymerase chain reaction probes. RESULTS:The three groups were balanced for baseline and surgical parameters.BB536 was never found at any time-points studied.At day 0,La1 was present in 6/10(60%)patients in either stools or by biopsy in group C,in 3/11(27.2%)in group B,and none in the placebo group(P=0.02,C vs A).There was a linear correlation between dose given and number of adher- ent La1(P=0.01).The rate of mucosal colonization by enterobacteriacae was 30%(3/10)in C,81.8%(9/11) in B and 70%(7/10)in A(P=0.03,C vs B).The Enterobacteriacae count in stools was 2.4(log10 scale) in C,4.6 in B,and 4.5 in A(P=0.07,C vs A and B). The same trend was observed for colonizing enterococ- ci.La1 was not found at day+5.We observed greater expression of CD3,CD4,CD8,and naive and memory lymphocyte subsets in group C than in group A with a dose response trend(C>B>A).Treatment didnot affect DC phenotype or activation,but after ex vivo stimulation with lipopolysaccharides,groups C and B had a lower proliferation rate compared to group A (P=0.04).Moreover,dendritic phenotypes CD83-123, CD83-HLADR,and CD83-11c(markers of activation) were significantly less expressed in patients colonized with La1(P=0.03 vs not colonized). CONCLUSION:La1,but not BB536,adheres to the colonic mucosa,and affects intestinal microbiota byreducing the concentration of pathogens and modulates local immunity.Luca Gianotti Lorenzo Morelli Francesca Galbiati Simona Rocchetti Sara Coppola Aldo Beneduce Cristina Gilardini Daniela Zonenschain Angelo Nespoli Marco Braga 2010World Journal of Gastroenterology2010,16,2:18
13Evaluation of latent links between irritable bowel syndrome and sleep quality显示文摘AIM:To examine the links between quality of sleep and the severity of intestinal symptoms in irritable bow-el syndrome(IBS).METHODS:One hundred and forty-two outpatients(110female,32 male)who met the Rome Ⅲ criteria for IBS with no psychiatric comorbidity were consecutively en-rolled in this study.Data on age,body mass index(BMI),and a set of life-habit variables were recorded,and IBS symptoms and sleep quality were evaluated using the questionnaires IBS Symptom Severity Score(IBS-SSS)and Pittsburgh Sleep Quality Index(PSQI).The associa-tion between severity of IBS and sleep disturbances was evaluated by comparing the global IBS-SSS and PSQI score(Pearson's correlation and Fisher's exact test)and then analyzing the individual items of the IBS-SSS and PSQI questionnaires by a unitary bowel-sleep model based on item response theory(IRT).RESULTS:IBS-SSS ranged from mild to severe(120-470).The global PSQI score ranged from 1 to 17(median 5),and 60 patients were found to be poor sleepers(PSQI>5).The correlation between the global IBS-SSS and PSQI score indicated a weak association(r=0.2 and 95% CI:-0.03 to 0.35,P<0.05),which becomes stronger using our unitary model.Indeed,the IBS and sleep disturbances severities,estimated as latent variables,resulted significantly high intra-subject cor-relation(posterior mean of r=0.45 and 95% CI:0.17 to 0.70,P<0.05).Moreover,the correlations between patient features(age,sex,BMI,daily coffee and alcohol intake)and IBS and sleep disturbances were also ana-lyzed through our unitary model.Age was a signif icant regressor,with patients≤50 years old showing more severe bowel disturbances(posterior mean=-0.38,P<0.05)and less severe sleep disturbances(posterior mean=0.49,P<0.05)than older patients.Higher daily coffee intake was correlated with a lower sever-ity of bowel disturbances(posterior mean=-0.31,P<0.05).Sex(female)and daily alcohol intake(modest)were correlated with less severe sleep disturbances.CONCLUSION:The unitary bowel-sleep model based on IRT revealed a strong positive correlation between the severity of IBS symptoms and sleep disturbances.Massimo Bellini Angelo Gemignani Dario Gambaccini Simona Toti Danilo Menicucci Cristina Stasi Francesco Costa Maria Gloria Mumolo Angelo Ricchiuti Remo Bedini Nicola de Bortoli Santino Marchi 2011World Journal of Gastroenterology2011,17,46:17
14Efficacy and safety of endoscopic prophylactic treatment with undiluted cyanoacrylate for gastric varices显示文摘AIM:To evaluate the efficacy and safety of undiluted N-butyl-2 cyanoacrylate plus methacryloxysulfolane(NBCM)as a prophylactic treatment for gastric varices(GV)bleeding.METHODS:This prospective study was conducted at a single tertiary-care teaching hospital between October 2009 and March 2013.Patients with portal hypertension(PH)and GV,with no active gastrointestinal bleeding,were enrolled in primary prophylactic treatment with NBCM injection without lipiodol dilution.Initial diagnosis of GV was based on endoscopy and confirmed with endosonography(EUS); the same procedure was used after treatment to confirm eradication of GV.After puncturing the GV with a regular injection needle,1 mL of undiluted NBCM was injected intranasally into GV.The injection was repeated as necessary to achieve eradication or until a maximum total volume of 3 mL of NBCM had been injected.Patients were followed clinically and evaluated with endoscopy at 3,6 and 12 mo.Later follow-ups were performed yearly.The main outcome measures were efficacy(GV eradication),safety(adverse events related to cyanoacrylate injection),recurrence,bleeding from GV and mortality related to GV treatment.RESULTS:A total of 20 patients(15 male)with PH and GV were enrolled in the study and treated with undiluted NBCM injection.Only 2(10%)patients had no esophageal varices(EV); 18(90%)patients were treated with endoscopic band ligation to eradicate EV before inclusion in the study.The patients were followed clinically and endoscopically for a median of 31 mo(range:6-40 mo).Eradication of GV was observed in all patients(13 patients were treated with 1 session and 7 patients with 2 sessions),with a maximum injected volume of 2 mL NBCM.One patient had GV recurrence,confirmed by EUS,at 6-mo follow-up,and another had late recurrence with GV bleeding after 35 mo of follow-up; overall,GV recurrence was observed in 2 patients(10%),after 6 and 35 mo of follow-up,and GV bleeding rate was 5%(1 patient).Mild epigastric pain was reported by 3 patients(15%).No mortality or major complications,including embolism,or damage to equipment were observed.CONCLUSION:Endoscopic injection with NBCM,without lipiodol,may be a safe and effective treatment for primary prophylaxis of gastric variceal bleeding.Matheus Cavalcante Franco Gustavo Flores Gomes Frank Shigeo Nakao Gustavo Andrade de Paulo Angelo Paulo Ferrari Jr Ermelindo Della Libera Jr 2014World Journal of Gastrointestinal Endoscopy2014,6,6:16
15Exocrine pancreatic insufficiency in adults:A shared position statement of the Italian association for the study of the pancreas显示文摘This is a medical position statement developed by the Exocrine Pancreatic Insufficiency collaborative group which is a part of the Italian Association for the Study of the Pancreas(AISP).We covered the main diseases associated with exocrine pancreatic insufficiency(EPI)which are of common interest to internists/gastroenterologists,oncologists and surgeons,fully aware that EPI may also occur together with many other diseases,but less frequently.A preliminary manuscript based on an extended literature search(Medline/PubMed,Cochrane Library and Google Scholar)of published reports was prepared,and key recommendations were proposed.The evidence was discussed at a dedicated meeting in Bologna during the National Meeting of the Association in October 2012.Each of the proposed recommendations and algorithms was discussed and an initial consensus was reached.The final draft of the manuscript was then sent to the AISP Council for approval and/or modification.All concerned parties approved the final version of the manuscript in June 2013.Raffaele Pezzilli Angelo Andriulli Claudio Bassi Gianpaolo Balzano Maurizio Cantore Gianfranco Delle Fave Massimo Falconi Luca Frulloni the Exocrine Pancreatic Insufficiency collaborative(EPIc) Group 2013World Journal of Gastroenterology2013,19,44:16

17Effects of cold and warm cross-rolling on microstructure and texture evolution of AZ31B magnesium alloy sheet显示文摘Mg alloys conventionally rolled often present strong basal textures that affect negatively further deformations,limiting their applications.The present research found that cross-rolling experiences in adequate conditions can weaken those intense basal textures as a result of the interaction of deformation mechanisms and dynamic recrystallization.The effects of rolling temperature and strain rate on the microstructure and texture of an AZ31B magnesium alloy sheet generated heterogeneous microstructure where the initial basal texture was strengthened during cold cross-rolling and it was gradually weakening by the rolling reduction and the rolling temperature increases in such a way that a rather weak basal fiber was produced applying reductions higher than 15%at temperatures higher than 200℃.Their ODF functions supported the texture weakening,exhibiting a combination of two crystallographic orientations represented by{0001}<211^(-)0>and{0001}<101^(-)0>.Litzy Lina Choquechambi Catorceno Hamilton Ferreira Gomes de Abreu Angelo Fernando Padilha 2018Journal of Magnesium and Alloys2018,6,2:16
18Glycated hemoglobin and antidiabetic strategies as risk factors for hepatocellular carcinoma显示文摘AIM: To evaluate the relationship between glycemic control [assessed by glycated hemoglobin (HbA1c)], antidiabetic therapies and the risk of hepatocellular carcinoma (HCC).METHODS: We recruited 465 patients with HCC, 618 cases with liver cirrhosis and 490 controls with no liver disease. Among subjects with type 2 diabetes mellitus (DM2), the associations between the antidiabetic strategies and HbA1c level with HCC were determined through 2 series of multivariate logistic regression models using cirrhotic patients and controls as comparison groups. RESULTS: DM2 prevalence was 31.2% in patients with HCC, 23.2% in cirrhotic patients and 12.6% in controls (P < 0.0001). In 86% of study subjects, DM2 had been diagnosed for more than 1 year before the HCC diagnosis. HCC patients with DM2 had a 1.52.5fold increased risk of liver cancer. The HbA1c mean levels were signif icantly higher in DM2 patients with HCC than in cirrhoticand control DM2 patients. Antidiabetic treatment with metformin was more common among cirrhotic and control DM2 subjects than among cases with HCC. In both series of multivariate analyses, treatment with metformin signif icantly reduced the risk of HCC by more than 80% compared with sulphonylureas and insulin therapy. No signif icant differences were seen between sulphonylureas and insulin treatment. Elevated HbA1c levels were positively related to the risk for HCC in diabetic patients, with a 26%50% increase in risk for each 1% increase in HbA1c values.CONCLUSION: In patients with preexisting DM2, the risk of HCC is positively associated with poor chronic glycemic control and significantly decreased by metformin therapy.Valter Donadon Massimiliano Balbi Francesca Valent Angelo Avogaro 2010World Journal of Gastroenterology2010,16,24:15
19Small-for-size syndrome in adult-to-adult living-related liver transplantation显示文摘Small-for-size syndrome (SFSS) in adult-to-adult living-related donor liver transplantation (LRLT) remains the greatest limiting factor for the expansion of segmental liver transplantation from either cadaveric or living donors. Portal hyperperfusion, venous pathology, and the arterial buffer response signif icantly contribute to clinical and histopathological manifestations of SFSS. Here, we review the technical aspects of surgical and radiological procedures developed to treat SFSS in LRLT, along with the pathophysiology of this condition.Salvatore Gruttadauria Duilio Pagano Angelo Luca Bruno Gridelli 2010World Journal of Gastroenterology2010,16,40:15
20Molecular targeting agents associated with transarterial chemoembolization or radiofrequency ablation in hepatocarcinoma treatment显示文摘Hepatocellular carcinoma(HCC)is the fifth most common cause of cancer in the world.According to Barcelona Clinic Liver Cancer modified criteria,patients with early stage disease are candidate to radiofrequency ablation(RFA),while patients with intermediate stage HCC are usually treated by transarterial chemoembolization(TACE).TACE and RFA induce a transient devascularisation effect followed by strong neoangiogenic stimulus.In fact,after these procedures,it has been demonstrated an up-regulation of pro-angiogenic and growth factors such as vascular endothelial growth factor-A,which might contribute to accelerated progression in patients with incomplete response.Several studies have demonstrated that MAP-kinase and AKT pathways,in addition to neo-angiogenesis,have an important role in the development of HCC.In advanced HCC,anti-angiogenic therapy and tyrosine kinases inhibitors showed potential clinical benefit.Actually,a number of clinical studies are ongoing testing these agents in combination with TACE or RFA.In this paper,we have reviewed the most recent preclinical and clinical results of such trials.Girolamo Ranieri Ilaria Marech Vito Lorusso Veronica Goffredo Angelo Paradiso Domenico Ribatti Cosmo Damiano Gadaleta 2014World Journal of Gastroenterology2014,20,2:14
