1Advances in diagnosis, treatment and palliation of pancreatic carcinoma: 1990-2010显示文摘Several advances in genetics, diagnosis and palliation of pancreatic cancer (PC) have occurred in the last decades. A multidisciplinary approach to this disease is therefore recommended. PC is relatively common as it is the fourth leading cause of cancer related mortality. Most patients present with obstructive jaundice, epigastric or back pain, weight loss and anorexia. Despite improvements in diagnostic modalities, the majority of cases are still detected in advanced stages. The only curative treatment for PC remains surgical resection. No more than 20% of patients are candidates for surgery at the time of diagnosis and survival remains quite poor as adjuvant therapies are not very effective. A small percentage of patients with borderline non-resectable PC might benefit from neo-adjuvant chemoradiation therapy enabling them to undergo resection; however, randomized controlled studies are needed to prove the benefits of this strategy. Patients with unresectable PC benefit from palliative interventions such as biliary decompression and celiac plexus block. Further clinical trials to evaluate new chemo and radiation protocols as well as identification of genetic markers for PC are needed to improve the overall survival of patients affected by PC, as the current overall 5-year survival rate of patients affected by PC is still less than 5%. The aim of this article is to review the most recent high quality literature on this topic.Chakshu Sharma Karim M Eltawil Paul D Renfrew Mark J Walsh Michele Molinari 2011World Journal of Gastroenterology2011,17,7:28
2大气二氧化氮与每日总死亡率、心血管和呼吸系统疾病死亡率的短期关联:398个城市的多中心分析显示文摘目的:采用统一的分析方案,评估全球多个国家/地区的二氧化氮(NO_(2))与总死亡率、心血管和呼吸系统疾病死亡率之间的短期关联。研究设计:采用两阶段的时间序列分析方法、过度离散的广义线性模型和多水平meta分析。研究地点:22个低到高收入国家/地区的398个城市。主要结局指标:1973—2018年逐日总死亡人数(6280万人)、心血管疾病死亡人数(1970万人)和呼吸系统疾病死亡人数(550万人)。结果:平均而言,NO_(2)浓度在滞后1天(前1天)每增加10μg/m^(3),会导致总死亡率、心血管和呼吸系统疾病死亡率分别增加0.46%(95%可信区间0.36%~0.57%)、0.37%(0.22%~0.51%)、0.47%(0.21%~0.72%)。在对共污染物(PM_(10)、PM_(2.5)、臭氧、二氧化硫和一氧化碳)进行调整后,这些关联仍然很稳定。所有3种死因的暴露-反应曲线几乎是线性的,没有明显的阈值。在398个城市中,可归因于高过假定零水平的NO_(2)浓度造成的死亡比例为1.23%(95%可信区间0.96%~1.51%)。结论:这项多中心研究提供了关于NO_(2)短期暴露与总死亡率、心血管和呼吸系统死亡风险之间的独立和线性关联的关键证据,说明通过加强NO_(2)的控制和监管限制标准,可获得人群水平的健康收益。孟夏 刘聪(校) 陈仁杰 郑湃(译) 阚海东(校) Francesco Sera Ana Vicedo-Cabrera Ai Milojevic Maria Guo Yuming Tong Shilu Micheline de Sousa Zanotti Stagliorio Coelh Paulo Hilario Nascimento Saldiva Eric Lavigne Patricia Matus Correa Nicolas Valdes Ortega Samuel Osorio Garcia Jan Kysely Ales Urban Hans Orru Marek Maasikmets Jouni J K Jaakkola Niilo Ryti Veronika Huber Alexandra Schneider Klea Katsouyanni Antonis Analitis Masahiro Hashizume Yasushi Honda Chris Fook Sheng Ng Baltazar Nunes João Paulo Teixeira Iulian Horia Holobaca Simona Fratianni Ho Kim Aurelio Tobias Carmeníniguez Bertil Forsberg ChristoferÅström Martina S Ragettli Yue-Liang Leon Guo Shih-Chun Pan Shanshan Li Michelle L Bell Antonella Zanobetti Joel Schwartz Tangchun Wu Antonio Gasparrini 2021英国医学杂志中文版2021,24,8:7
3Giant hepatic extra-gastrointestinal stromal tumor treated with cytoreductive surgery and adjuvant systemic therapy:A case report and review of literature显示文摘BACKGROUND Primary extra-gastrointestinal stromal tumors(E-GIST)of the liver are rare.The clinical presentation may range from asymptomatic to bleeding or manifestations of mass effect.Oncologic surgery followed by adjuvant therapy with imatinib is the standard of care.However,under specific circumstances,a cytoreductive approach may represent a therapeutic option.We describe herein the case of an 84-year-old woman who presented with a tender,protruding epigastric mass.Abdominal computed tomography scan revealed a large,heterogeneous mass located across segments III,IV,V,and VIII of the liver.The initial approach was transarterial embolization of the tumor,which elicited no appreciable response.Considering the large size and central location of the tumor and the advanced age of the patient,non-anatomic complete resection was indicated.Due to substantial intraoperative bleeding and hemodynamic instability,only a near-complete resection could be achieved.Histopathology and immunohistochemical staining confirmed the diagnosis of primary E-GIST of the liver.Considering the risk/benefit ratio for therapeutic options,debulking surgery may represent a strategy to control pain and prolong survival.CASE SUMMARY Here,we present a case report of a patient diagnosed with E-GIST primary of the liver,which was indicated a cytoreductive surgery and adjuvant therapy with imatinib.CONCLUSION E-GIST primary of the liver is a rare conditional,the treatment is with systemic therapy and total resection surgery.However,a cytoreductive surgery will be necessary when a complete resection is no possible.Michel Ribeiro Fernandes Caroline Lorenzoni Almeida Ghezzi Tomaz J M Grezzana-Filho Flávia Heinz Feier Ian Leipnitz Aljamir Duarte Chedid Carlos Thadeu Schmidt Cerski Marcio Fernandes Chedid Cléber RositoPinto Kruel 2021World Journal of Gastrointestinal Surgery2021,13,3:3
4Appropriateness of systemic treatments in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors显示文摘AIM:To evaluate systemic treatment choices in unresectable metastatic well-differentiated pancreatic neuroendocrine tumors(PNETs)and provide consensus treatment recommendations.METHODS:Systemic treatment options for pancreatic neuroendocrine tumors have expanded in recent years to include somatostatin analogs,angiogenesis inhibitors,inhibitors of mammalian target of rapamycinand cytotoxic agents.At this time,there is little data to guide treatment selection and sequence.We therefore assembled a panel of expert physicians to evaluate systemic treatment choices and provide consensus treatment recommendations.Treatment appropriateness ratings were collected using the RAND/UCLA modified Delphi process.After studying the literature,a multidisciplinary panel of 10 physicians assessed the appropriateness of various medical treatment scenarios on a 1-9 scale.Ratings were done both before and after an extended discussion of the evidence.Quantitative measurements of agreement were made and consensus statements developed from the second round ratings.RESULTS:Specialties represented were medical and surgical oncology,interventional radiology,and gastroenterology.Panelists had practiced for a mean of15.5 years(range:6-33).Among 202 rated scenarios,disagreement decreased from 13.2%(26 scenarios)before the face-to-face discussion of evidence to 1%(2)after.In the final ratings,46.5%(94 scenarios)were rated inappropriate,21.8%(44)were uncertain,and30.7%(62)were appropriate.Consensus statements from the scenarios included:(1)it is appropriate to use somatostatin analogs as first line therapy in patients with hormonally functional tumors and may be appropriate in patients who are asymptomatic;(2)it is appropriate to use everolimus,sunitinib,or cytotoxic chemotherapy therapy as first line therapy in patients with symptomatic or progressive tumors;and(3)beyond first line,these same agents can be used.In patients with uncontrolled secretory symptoms,octreotide LAR doses can be titrated up to 60 mg every4 wk or up to 40 mg every 3 or 4 wk.CONCLUSION:Using the Delphi process allowed physician experts to systematically obtain a consensus on the appropriateness of a variety of medical therapies in patients with PNETs.Jonathan R Strosberg George A Fisher Al B Benson Lowell B Anthony Bulent Arslan John F Gibbs Edward Greeno Renuka V Iyer Michelle K Kim William J Maples Philip A Philip Edward M Wolin Dasha Cherepanov Michael S Broder 2015World Journal of Gastroenterology2015,21,8:2
5Senescent human hepatocytes express a unique secretory phenotype and promote macrophage migration显示文摘AIM:To develop a model of stress-induced senescence to study the hepatocyte senescence associated secretory phenotype(SASP).METHODS:Hydrogen peroxide treatment was used to induce senescence in the human Hep G2 hepatocyte cell line.Senescence was confirmed by cytochemical staining for a panel of markers including Ki67,p21,heterochromatin protein 1β,and senescence-associated-β-galactosidase activity.Senescent hepatocytes were characterised by gene expression arrays and quantitative polymerase chain reaction(q PCR),and conditioned media was used in proteomic analyses,a human chemokine protein array,and cell migration assays to characterise the composition and function of the hepatocyte SASP.RESULTS:Senescent hepatocytes induced classical markers of senescence(p21,heterochromatin protein1β,and senescence-associated-β-galactosidase activity);and downregulated the proliferation marker,Ki67.Hepatocyte senescence induced a 4.6-fold increase in total secreted protein(P=0.06)without major alterations in the protein profile.Senescence-induced genes were identified by microarray(Benjamini Hochbergcorrected P<0.05);and,consistent with the increase in secreted protein,gene ontology analysis revealed a significant enrichment of secreted proteins among inducible genes.The hepatocyte SASP included characteristic factors such as interleukin(IL)-8 and IL-6,as well as novel components such as SAA4,IL-32and Fibrinogen,which were validated by q PCR and/or chemokine protein array.Senescent hepatocyteconditioned medium elicited migration of inflammatory(granulocyte-macrophage colony stimulating factor,GM-CSF-derived),but not non-inflammatory(CSF-1-derived)human macrophages(P=0.022),which could contribute to a pro-inflammatory microenvironment in vivo,or facilitate the clearance of senescent cells.CONCLUSION:Our novel model of hepatocyte senescence provides insights into mechanisms by which senescent hepatocytes may promote chronic liver disease pathogenesis.Katharine M Irvine Richard Skoien Nilesh J Bokil Michelle Melino Gethin P Thomas Dorothy Loo Brian Gabrielli Michelle M Hill Matthew J Sweet Andrew D Clouston Elizabeth E Powell 2014World Journal of Gastroenterology2014,20,47:2
