Inflammatory bowel diseases (IBD) are chronic inflammatory disorders of the gastrointestinal tract, strongly associated with an increased risk of colorectal cancer development. Parasitic infections caused by helminths have been shown to modulate the host's immune response by releasing immunomodulatory molecules and inducing regulatory T cells (Tregs). This immunosuppressive state provoked in the host has been considered as a novel and promising approach to treat IBD patients and alleviate acute intestinal inflammation...

OBJECTIVES: Cholangiocarcinoma (CCA) is a biliary malignancy found primarily in adults. The incidence of CCA in children is unknown. The aim of this study was to describe characteristics of CCA in children and adolescents. METHODS: Using the Surveillance, Epidemiology, and End Results Program (SEER 18) database, we identified incident cases of CCA diagnosed at <20 years of age during the period of 1973-2013. Additionally, we reviewed published case reports describing pediatric patients with CCA...

Neuroendocrine tumors (NETs) are neoplasms arising from dispersed neuroendocrine cells, localized to the gastrointestinal tract (GIT), lungs, adrenal medulla, and other sites. The term "carcinoid tumor" is usually limited to NETs of the lung and GIT. Ovarian carcinoids are uncommon, accounting for 0.1% of ovarian malignancies and 5% of all NETs. Primary ovarian tumors arise in pure form or as a component of teratomas, while ovarian NET metastases are predominantly from gastrointestinal primaries. To the best of our knowledge, there are only two previous reports of bronchopulmonary carcinoids (PCs) metastasizing to the ovaries...

BACKGROUND/AIMS: Esophageal squamous cell carcinoma (ESCC) is the most aggressive type of cancer. Mutation of tumor suppressor gene p53 is observed in many gastrointestinal malignancies including ESCC. The immunohistochemical protein expression of mutant p53 has been proposed as a potential tool to evaluate the biological behavior of ESCC. Predictive value of p53 for survival is debatable, hence this study was formulated to know the survival of patients with p53 expression in ESCC. PATIENTS AND METHODS: We prospectively included 91 consecutive patients of ESCC from August 2014 to August 2016...

BACKGROUND AND AIM: The risk of lymph node metastasis of a small rectal carcinoid tumor (<10 mm) is known to be lower than that of tumors at other gastrointestinal sites. Although rectal carcinoid tumors can be treated by endoscopic resection, the resected specimen may be incomplete. The consequences of an incomplete resection are not well known. METHOD: From December 2008 to November 2015, cases of rectal carcinoid tumors resected by endoscopic resection techniques such as endoscopic submucosal dissection (ESD), or endoscopic mucosal resection using band ligation device (EMR-L), or cap aspiration (EMR-C) were enrolled...

In France, upper gastrointestinal haemorrhages have an estimated annual incidence of 143 cases per 100,000 inhabitants. Classically, two types of digestive hemorrhage are described: acute and chronic digestive hemorrhages. Upper endoscopy is carried out in case of hematemesis or melena. It requires that the patient has been fasting for at least 6hours for solids and 3hours for liquids. The main etiologies of hemorrhagic hemorrhage of the origin are the vascular abnormalities, inflammatory or drug-induced ulcerations, intestinal tumors, Meckel's diverticulum, and Dieulafoy ulcer...

BACKGROUND: Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the role of surgery in metastatic disease of the thyroid. Isolated thyroidectomy has been proposed as a local disease control option to palliate and prevent the potential morbidity of tumor extension related to the airway...

OBJECTIVE: One of the critical mechanisms of gastrointestinal cancer pathogenesis is the silencing of death associated protein kinase 1 (DAPK1), which could be caused by aberrant methylation of the promoter. However, the relationship between DAPK1 methylation and the risk of gastrointestinal cancer is still controversial. Hence, we conducted this study to determine the potential correlation. METHODS: Eligible publications were searched in the Pubmed, Embase, and Cochrane Library through November 2016 according to the inclusion criteria and exclusion criteria...

Inflammatory bowel disease (IBD) is an immune-mediated inflammatory condition causing inflammation of gastrointestinal and systemic cells, with an increasing prevalence worldwide. Many factors are known to trigger and maintain inflammation in IBD including the innate and adaptive immune systems, genetics, the gastrointestinal microbiome and several environmental factors. Our knowledge of the involvement of the immune system in the pathophysiology of IBD has advanced rapidly over the last two decades, leading to the development of several immune-targeted treatments with a biological source, known as biologic agents...

AIM: To evaluate endoscopic ultrasound (EUS)-guided biopsies for the pretreatment characterization of gastrointestinal stromal tumors (GIST) to personalize the management of patients. METHODS: All patients with lesions suspected to be GIST who were referred for EUS-sampling at a tertiary Swedish center were eligible for inclusion 2006-2015. During the observational study phase (2006-2011), routine fine-needle-aspiration (EUS-FNA) was performed. In 2012-2015, we converted to an interventional, randomized protocol with dual sampling EUS-FNA and fine-needle-biopsy-sampling (EUS-FNB) for all lesions...

BACKGROUND: Clostridium septicum-infected aortic aneurysm is a fatal and rare disease. We present a fatal case of C. septicum-infected aortic aneurysm and a pertinent literature review with treatment suggestions for reducing mortality rates. CASE PRESENTATION: A 58-year-old Japanese man with an unremarkable medical history presented with a 3-day history of mild weakness in both legs, and experienced paraplegia and paresthesia a day before admission. Upon recognition of signs of an abdominal aortic aneurysm and paraplegia, we suspected an occluded Adamkiewicz artery and performed a contrast-enhanced computed tomography scan, which revealed an aortic aneurysm with periaortic gas extending from his chest to his abdomen and both kidneys...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

RATIONALE: Cronkhite-Canada Syndrome (CCS) is an idiopathic, nonhereditary syndrome haracterized by gastrointestinal (GI) polyposis and ectodermal changes including alopecia, onychatrophia, and pigmentation. CCS colon polyps were previously considered to be benign neoplasms. However, serrated adenoma was reported to be associated with malignant neoplasms in some cases of gastric and colorectal carcinomas, and esophageal cancers. Although malignant colon and gastric cancer have been reported in CCS, reports of distant metastasis have been rare in CCS...

With the recent advent of whole genome and transcriptome sequencing technologies, long non-coding RNAs have been brought into the spotlight in molecular biology. H19 was one of the first reported long non-coding RNAs; its expression is high in embryonic organs and absent or greatly reduced in most adult tissues. Accumulating evidence suggests that H19 plays crucial roles in embryogenesis. However, its levels are increased in different cancers, including breast, hepato-gastrointestinal, urological, respiratory, and brain tumors...

Plasmablastic lymphoma (PBL) is a rare B-cell lymphoma occurring mainly in HIV patients. The tumor frequently involves extranodal sites such as the oral cavity, nasal cavity, gastrointestinal tract, skin, and lungs. The neoplastic cells are characterized by a plasmablastic appearance and typical immunophenotype that indicates plasma cell differentiation. Herein, we report a case of intraocular involvement by plasmablastic lymphoma in a HIV patient with a long history of cytomegalovirus retinitis and loss of vision...

Constitutive activating mutations in KIT and platelet-derived growth factor receptor α ( PDGFRα) are heavily involved in the pathobiology of gastrointestinal stromal tumors (GISTs). This disease has served as an effective "proof-of-concept" model for targeting gain-of-function kinase mutations in cancer. This review discusses the current standard of care in terms of pharmacotherapy in the management of localized and metastatic GISTs.

Disruption of the gastrointestinal epithelial barrier is a hallmark of chronic inflammatory bowel diseases (IBDs). The transmembrane protein claudin 2 (CLDN2) is a component of epithelial tight junctions (TJs). In the intestines of patients with IBDs, the expression of the pore-forming TJ protein CLDN2 is upregulated. Although CLDN2 is involved in these leaky barriers, whether it can be a target to enhance TJ integrity is unknown because a CLDN2-specific inhibitor has not been developed. Here, we used DNA immunization to generate a monoclonal antibody (mAb) that recognized an extracellular loop of CLDN2...
