| 1 | Colorectal cancer in inflammatory bowel disease:What is the real magnitude of the risk?显示文摘The association between inflammatory bowel disease(IBD) and colorectal cancer(CRC) has been recognised since 1925 and still accounts for 10%-15% of deaths in IBD.IBD-associated CRC(IBD-CRC) affects patients at a younger age than sporadic CRC.The prognosis for sporadic CRC and IBD-CRC is similar,with a 5-year survival of approximately 50%.Identifying at risk patients and implementing appropriate surveillance for these patients is central to managing the CRC risk in IBD.The increased risk of colorectal cancer in association with IBD is thought to be due to genetic and acquired factors.The link between inflammation and cancer is well recognised but the molecular biology,immune pathobiology and genetics of IBD-CRC are areas of much ongoing research.This review examines the literature relating to IBD-CRC,focusing on the incidence of IBD-CRC and examining potential risk factors including age at diagnosis,gender,duration and extent of colitis,severity of inflammation,family history of sporadic CRC and co-existent primary sclerosing cholangitis(PSC).Confirmed risk factors for IBD-CRC are duration,severity and extent of colitis,the presence of co-existent PSC and a family history of CRC.There is insufficient evidence currently to support an increased frequency of surveillance for patients diagnosed with IBD at a younger age.Evidence-based guidelines advise surveillance colonoscopy for patients with colitis 8 to 10 years after diagnosis,with the interval for further surveillance guided by risk factors(extent of disease,family history of CRC,post-inflammatory polyps,concomitant PSC,personal history of colonic dysplasia,colonic strictures).There is a move away from using random colonic biopsies towards targeted biopsies aimed at abnormal areas identified by newer colonoscopic techniques(narrow band imaging,chromoendoscopy,confocal microendoscopy). | Jessica K Dyson Matthew D Rutter | 2012 | World Journal of Gastroenterology2012，18，29： | 22 |
| 2 | Genotype phenotype classification of hepatocellular adenoma显示文摘Studies that compare tumor genotype with phenotype have provided the basis of a new histological/molecular classification of hepatocellular adenomas. Based on two molecular criteria (presence of a TCF1/HNF1α or β-catenin mutation), and an additional histological criterion (presence or absence of an inflammatory infiltrate), subgroups of hepatocellular adenoma can be defined and distinguished from focal nodular hyperplasia. Analysis of 96 hepatocellular adenomas performed by a French collaborative network showed that they can be divided into four broad subgroups: the fi rst one is defi ned by the presence of mutations in TCF1 gene inactivating the hepatocyte nuclear factor 1 (HNF1α); the second by the presence of β-catenin activating mutations; the category without mutations of HNF1α or β-catenin is further divided into 2 subgroups depending on the presence or absence of in? ammation. Therefore, the approach to the diagnosis of problematic benign hepatocytic nodules may be entering a new era directed by new molecular information. It is hoped that immunohistological tools will improve significantly diagnosis of liver biopsy in our ability to distinguish hepatocellular adenoma from focal nodular hyperplasia (FNH), and to delineate clinically meaningful entities within each group to define the best clinical management. The optimal care of patients with a liver nodule will benefit from the recent knowledge coming from molecular biology and the combined expertise of hepatologists, pathologists, radiologists, and surgeons. | Paulette Bioulac-Sage Jean Frédéric Blanc Sandra Rebouissou Charles Balabaud Jessica Zucman-Rossi | 2007 | World Journal of Gastroenterology2007，13，19： | 7 |

| 6 | Lack of correlation between Treg quantification assays in inflammatory bowel disease patients显示文摘AIM:To compare the number of regulatory T-cells( Tregs) measured by flow cytometry with those obtained using a real-time quantitative PCR(q PCR) method in patients suffering from inflammatory bowel disease(IBD).METHODS:Tregs percentages obtained by both flow cytometry and q PCR methods in 35 adult IBD patients,18 out of them with Crohn′s disease(CD)and 17 with ulcerative colitis(UC)were compared to each other as well as to scores on two IBD activity questionnaires using the Harvey Bradshaw Index(HBI)for CD patients and the Simple Colitis Clinical Activity Index(SCCAI)for UC patients.The Treg percentages by flow cytometry were defined as CD4+CD25highCD127lowFOXP3+cells in peripheral blood mononuclear cells,whereas the Treg percentages by q PCR method were determined as FOXP3 promoter demethylation in genomic DNA.RESULTS:We found an average of 1.56%±0.78%Tregs by using flow cytometry,compared to 1.07%±0.53%Tregs by using q PCR in adult IBD patients.There were no significant correlations between either the percentages of Tregs measured by flow cytometry or q PCR and the HBI or SCCAI questionnaire scores in CD or UC patients,respectively.In addition,there was no correlation between Treg percentages measured by q PCR and those measured by flow cytometry(r=-0.06,P=0.73;Spearman Rho).These data suggest that,either Treg-related immune function or the clinical scores in these IBD patients did not accurately reflect actual disease activity.Until the cause(s)for these differences are more clearly defined,the resultssuggest caution in interpreting studies of Tregs in various inflammatory disorders.CONCLUSION:The two methods did not produce equivalent measures of the percentage of total Tregs in the IBD patients studied which is consistent with the conclusion that Tregs subtypes are not equally detected by these two assays. | Gunnar Brandhorst Darinka Todorova Petrova Sebastian Weigand Christoph Eberle Nicolas von Ahsen Jessica Schmitz Frank Christian Schultze Dirk Raddatz Michael Karaus Michael Oellerich Philip D Walson | 2015 | World Journal of Gastroenterology2015，21，11： | 2 |
| 7 | Effect of hepatic artery embolization on liver hypertrophy response in a rabbit liver VX2tumor model显示文摘BACKGROUND:Portal vein embolization not only induces hypertrophy of the non-embolized liver,but also enhances tumor growth.The latter could be prevented by embolizing the hepatic arteries supplying the tumor-bearing liver segments.This study aimed to determine the effects of transcatheter arterial embolization(TAE)on tumor volume and liver regeneration in a rabbit VX2 tumor model.METHODS:Twenty-three rabbits underwent subcapsular tumor implantation with a VX2 tumor.Two weeks after implantation,18 rabbits were used for TAE experiments,5were for sham controls.Tumor response and liver regeneration response of the embolized cranial and non-embolized caudal liver lobes were assessed by CT volumetry,liver to body weight index,and the amount of proliferating hepatocytes.RESULTS:All super-selective arterial tumor embolization procedures were performed successfully.Despite embolization,the tumor volume increased after an initial steady state.The tumor volume after embolization was smaller than that of the sham group,but this difference was not significant.Massive necrosis of the tumor,however,was seen after embolization,without damage of the surrounding liver parenchyma.There was a significant atrophy response of the tumor bearing cranial lobe after super-selective arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized,caudal lobe.This regeneration response was confirmed histologically by a significantly higher number of proliferating hepatocytes on the Ki-67 stained slides.CONCLUSIONS:Super-selective,bland arterial coil embolization causes massive necrosis of the tumor,despite increase of volume on CT scan.Atrophy of the tumor bearing liver lobe is seen after arterial embolization of the tumor with a concomitant hypertrophy response of the non-embolized lobe,despite absence of histological damage of the tumor-surrounding liver parenchyma. | Krijn P van Lienden Lisette T Hoekstra Jessica D van Trigt Joris J Roelofs Otto M van Delden Thomas M van Gulik | 2013 | Hepatobiliary & Pancreatic Diseases International2013，12，6： | 2 |
| 8 | Intravascular large B-cell lymphoma presenting with altered mental status: A case report显示文摘BACKGROUND Intravascular large B-cell lymphoma(IVLBCL)is a rare and aggressive subtype of non-Hodgkin lymphoma with a varied presentation and no pathognomonic findings.Early diagnosis is critical to altering the disease course as early treatment with chemoimmunotherapy is required to prevent a rapidly fatal outcome.Strategies including improved awareness of this clinical entity through publication of cases with unique presentations are essential to prompt consideration of IVLBCL early in the disease workup.Here,we present a case of IVLBCL presenting with altered mental status and systemic organ dysfunction.CASE SUMMARY A 61-year-old male patient presented with flu-like symptoms and a high fever.He experienced rapid clinical deterioration with liver,kidney failure,and shock despite rapid antibiotic administration and supportive care.A broad infectious workup was negative.Intracranial imaging revealed nonspecific changes to the corpus callosum suspicious for vasculitis.Renal biopsy was non-diagnostic.After further progression of his symptoms,the family elected to withdraw care and the patient died shortly thereafter.Post-mortem analysis revealed clear multi-organ involvement by IVLBCL,prompting re-examination of the ante-mortem renal biopsy that also identified IVLBCL involvement.CONCLUSION IVLBCL is a rare disease.Communication with specialties and early biopsy is critical to establishing the diagnosis and initiating therapy. | Christopher Robert D’Angelo Kimberly Ku Jessica Gulliver Julie Chang | 2019 | World Journal of Clinical Oncology2019，10，12： | 2 |
