BACKGROUND: Neuroendocrine tumors (NETs) have a uniquely indolent biology. Management focuses on tumor and hormonal burden reduction. Data on cytoreduction with extrahepatic disease remain limited. OBJECTIVE: We sought to define the outcomes of cytoreduction for metastatic NETs with extrahepatic metastases. METHODS: Patients undergoing cytoreductive surgery for grade 1 or 2 NETs with extrahepatic metastases (with or without intrahepatic disease) were identified from an institutional database (2003-2014)...

Death receptor 3 (DR3), a member of the tumor necrosis factor receptor (TNFR) superfamily, has been implicated in regulating T-helper type-1 (TH 1), type-2 (TH 2), and type-17 (TH 17) responses as well as regulatory T cell (Treg ) and innate lymphoid cell (ILC) functions during immune-mediated diseases. However, the role of DR3 in controlling lymphocyte functions in inflammatory bowel disease (IBD) is not fully understood. Recent studies have shown that activation of DR3 signaling modulates Treg expansion suggesting that stimulation of DR3 represents a potential therapeutic target in human inflammatory diseases, including Crohn's disease (CD)...

The pharmacological management of inflammatory bowel disease (IBD) over the last two decades has transitioned from reliance on aminosalycilates, corticosteroids and immunomodulators to earlier treatment with anti-tumor necrosis factor (anti-TNF) therapy. Nevertheless, 20-30% of patients discontinue anti-TNF therapy for primary non-response and another 30-40% for losing response within one year of treatment. These undesirable therapeutic outcomes can be attributed to pharmacokinetic (anti-drug antibodies and/or low drug concentrations) or pharmacodynamic issues characterized by a non-TNF driven inflammation...

MEDICAL HISTORY AND CLINICAL FINDINGS:  A 43-year old male patient was admitted because of diffuse abdominal discomfort for two days, which had started in the upper abdomen; medical history, no previous surgical interventions at the abdomen. INVESTIGATIONS:  Gastroscopy and abdominal ultrasound revealed only a mild gastritis. Laboratory parameters: showed only a slight leucocytosis (10 610/µL). On the 1st day of the hospital stay, the patient developed a worsening of the abdominal symptoms with distended abdomen, sounding bowel movements and recurrent vomiting, which were interpreted as acute abdomen by the surgeon on call leading to the indication of a surgical intervention...

Radiotracers targeting prostate-specific membrane antigen (PSMA), including [18 F]DCFPyL, have been extensively investigated as a means to image prostate cancer more accurately. We present the case of a man with oligometastatic prostate cancer who was also diagnosed with a metastatic small bowel carcinoid tumor following the detection of indeterminate findings on a [18 F]DCFPyL PET and discuss how this case highlights the utility of a newly proposed reporting system for PSMA-targeted PET (PSMA-RADS version 1...

Inflammatory bowel disease (IBD) is a collection of inflammatory conditions of colon and small intestine which affect millions of individuals worldwide and the prevalence amount is on the rise. The organ failure as well as loss of tissue function is because of the inflammatory reaction which is the major contributor of tissue healing leading to lifelong debilitation. To stop the tough consequences of inflammation every patient pursues alternative therapy to relieve symptoms. Green tea polyphenols (GTPs) play significant roles in down regulating signaling pathways because GTPs exert effective antioxidant properties and regulate Toll-like receptor 4 (TLR4) expression via certain receptor, inhibited endotoxin-mediated tumor necrosis factor alpha (TNF-α) production by blocking transcription nuclear factor-kappa B (NF-kB) activation and upstream of mediated I kappa B kinase complex pathway activities, as well as intrusion with the flow of cytokines and synthesis of cyclooxygenase-2 (COX-2)...

Lynch syndrome is the most common hereditary cancer syndrome, the most common cause of heritable colorectal cancer, and the only known heritable cause of endometrial cancer. Other cancers associated with Lynch syndrome include cancers of the ovary, stomach, urothelial tract, and small bowel, and less frequently, cancers of the brain, biliary tract, pancreas, and prostate. The oncogenic tendency of Lynch syndrome stems from a set of genomic alterations of mismatch repair proteins. Defunct mismatch repair proteins cause unusually high instability of regions of the genome called microsatellites...

The efficacy of immunotherapy varies widely among different gastrointestinal cancers. Response to immune checkpoint inhibitors is shown to correlate with tumor mutation load (TML), mismatch repair deficiency (dMMR) status, and programmed cell death-ligand 1 (PD-L1) expression. Herein, we quantify TML, dMMR, and PD-L1 expression and determine their interrelationship in gastrointestinal cancers. Here, a total of 4125 tumors from 14 different gastrointestinal cancer sites were studied using validated assays. Next-generation sequencing (NGS) was performed on genomic DNA isolated from formalin-fixed paraffin-embedded (FFPE) tumor specimens using the NextSeq platform...

Gastrointestinal stromal tumors (GISTs) are rare in pregnancy, with only 11 reported cases. Adjuvant imatinib therapy, which targets the most common driver mutations in GIST ( KIT and PDGFRA) , is recommended for patients with high-risk GIST, but it has known teratogenicity in the first trimester. A 34-year-old G3P2 woman underwent exploratory laparotomy at 16 weeks' gestation for a presumed adnexal mass. Surgical findings included normal adnexa and a 14-cm solid small bowel mass. The mass was resected en bloc with a segment of jejunum followed by a primary anastomosis...

Small bowel adenocarcinoma (SBA) is an aggressive disease with limited treatment options. Despite previous studies, its molecular genetic background has remained somewhat elusive. To comprehensively characterize the mutational landscape of this tumor type, and to identify possible targets of treatment, we conducted the first large exome sequencing study on a population-based set of SBA samples from all three small bowel segments. Archival tissue from 106 primary tumors with appropriate clinical information were available for exome sequencing from a patient series consisting of a majority of confirmed SBA cases diagnosed in Finland between the years 2003-2011...

BACKGROUND: Neuroendocrine tumors (NETs) of the gastrointestinal tract are a heterogeneous group of tumors which have different malignant potential and evolution. The World Health Organization (WHO) has set up a new classification of gastrointestinal NETs in 2010. However, it does not evaluate the risk of malignancy for each tumor. AIM: To evaluate the prognostic impact of the WHO classification in 2010 by reclassifying the tumor according to new recommendations and to identify histoprognostic factors to better predict changes...

Angiosarcoma is an aggressive mesenchymal sarcoma of endothelial cell origin with high mortality. Its occurrence in the small intestine is exceedingly low. In addition to the rarity of small intestine angiosarcoma, the nonspecific early clinical symptoms obscure the suspicion of such tumors and thereby delay the diagnosis. In a hope to improve the knowledge of this rare but fatal neoplasm, we report one case of angiosarcoma of duodenum and jejunum in a 73-year-old man. Furthermore, we summarize and analyze the common clinical features, tumor markers, treatment, and survival of previous reported cases of this malignancy...

Background: Vedolizumab (VDZ), an adhesion molecule inhibitor and infliximab (IFX), a tumor necrosis factor (TNF) blocker, are both approved as first-line induction agents in moderately to severely active ulcerative colitis (UC). However, there are no head-to-head studies comparing the relative effectiveness of the two agents. Here we provide a real-world comparison of these two agents. Methods: We conducted an ambidirectional cohort study of adult UC patients seen at our tertiary inflammatory bowel disease (IBD) center from 2012 to 2017...

Intestinal malrotation is a continuum of congenital anomalies due to lack of rotation or incomplete rotation of the fetal intestine around the superior mesenteric artery axis. The abnormal bowel fixation (by mesenteric bands) or absence of fixation of portions of the bowel increases the risk of bowel obstruction, acute or chronic volvulus, and bowel necrosis. The clinical presentation of patients with malrotation without, with intermittent, or with chronic volvulus can be problematic, with an important minority presenting late or having atypical or chronic symptoms, such as intermittent vomiting, abdominal pain, duodenal obstruction, or failure to thrive...
