A protocol-driven, systematic pathway was developed to allow rapid and coordinated investigation of patients with iron-deficiency anemia (IDA) in a nurse-delivered outpatient setting. The study objective was to assess the safety and efficacy of the pathway by 5-year outcome data for the exclusion of gastrointestinal (GI) malignancy. This is a 5-year follow-up study of 122 patients entered onto the pathway with negative initial upper and lower GI investigations. The study was conducted at Hereford County Hospital NHS Trust (a district general hospital serving 220,00 people)...

Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional treatment and will have little effect on the prognosis of the individual. This article reports a synchronous rectal carcinoid in a patient with hepatic flexure adenocarcinoma...

Long-term survivors of Hodgkin lymphoma (HL) experience several late adverse effects of treatment, with second malignant neoplasms (SMNs) and cardiovascular diseases (CVDs) being the leading causes of death in these patients. Other late effects have also been identified, such as pulmonary dysfunction, endocrinopathies (thyroid dysfunction, infertility), neck muscle atrophy, and persistent fatigue. HL survivors have two- to fourfold increased risks to develop SMNs and CVD compared with the general population...

BACKGROUND: Toyocamycin, an antibiotic agent isolated from Streptomyces species, has been shown to have anticancer and chemopreventive effects on various cancer cells. Until now, Toyocamycin-induced apoptosis has not been reported to be involved in the regulation between mitogen-activated protein kinases (MAPKs) and reactive oxygen species (ROS) production. METHODS: Cell viability assay, western blot, cell-cycle arrest, annexin V/propidium iodide assay, reactive oxygen species (ROS) production, mitochondrial membrane potential and intracellular Ca(2+) flux were assayed...

BACKGROUND: Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥65 or 75 years is used. Nowadays most of malignancies requiring surgical treatment are diagnosed in old population. Comorbidities and frailty represent well-known problems during and after surgery in elderly patients. Minimally invasive surgery offers earlier postoperative mobilization, less blood loss, lower morbidity as well as reduction in hospital stay and as such represents an interesting and validated option for elderly population...

Gastrointestinal secretory tumors, or gastroenteropancreatic neuroendocrine tumors, encompass a wide array of endocrine cell tumors. The significance of these tumors lies in their ability to alter physiology through hormone production as we well as in their malignant potential. Functioning tumors may present earlier due to symptomatology; conversely, non-functioning tumors are often diagnosed late as they reach large sizes, causing symptoms secondary to local mass effect. Imaging aids in the diagnosis, staging, and prognosis and provides key information for presurgical planning...

REVIEW
James Q Del Rosso, Leon Kircik
This article provides an update on the use of oral apremilast, a phosphodiesterase-4 (PDE4) inhibitor, for the treatment of plaque psoriasis. Emphasis is placed on safety evaluations, although efficacy considerations are also addressed. Both two-year and three -year data analyses support the favorable safety profile reported in pivotal trials with this agent. Although effective in many study subjects despite baseline characteristics, higher response rates were noted in those with a baseline psoriasis area and severity index (PASI) score <20 and in subjects not previously treated with systemic therapy for psoriasis...

BACKGROUND: Malignant pleural effusions (MPE) are a common complication of advanced malignancy, but little is known regarding their prevalence and overall burden on a population level. METHODS: We conducted a retrospective analysis of MPE associated hospitalizations using the Healthcare Cost and Utilization Project-Nationwide Inpatient Sample, Agency for Healthcare Research and Quality (HCUP-NIS 2012). Cases were included if MPE was coded as a primary or secondary diagnosis or if an unspecified pleural effusion was coded in addition to a diagnosis of cancer with either of these being the primary diagnosis...

PURPOSE: Squamous cell carcinoma of the anal canal (ASCC) accounts for 2-4% of gastrointestinal (GI) malignancies in the US and is increasing in incidence; however, genomic features of ASCC are incompletely characterized. Primary treatment of ASCC involves concurrent chemotherapy and radiation (CRT), but the mutational landscape of resistance to CRT is unknown. Here, we aim to compare mutational features of ASCC in the pre- and post-CRT setting. EXPERIMENTAL DESIGN: We perform whole exome sequencing of primary (n=31) and recurrent (n=31) ASCCs and correlate findings with clinical data...

BACKGROUND: Bevacizumab (BV) has been used to treat recurrent glioblastoma with a progression free survival of approximately 3-3.5 months. Typically, it is administered intravenously every 2-3 weeks at dosages ranging from 5-15 mg/kg. Serious side effects include GI tract perforations, hematologic disorders, intracranial hemorrhage, and malignant hypertension. We hypothesized that selective intracranial intra-arterial infusion (SIACI) of BV following blood/brain barrier disruption (BBBD) with mannitol may allow for reduced dosage, lower toxicity, and equivalent or superior progression free survival (PFS)...

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms (85%) of the gastrointestinal (GI) tract; duodenal GISTs constitute 3-5% of all GISTs and represent 10-30% of all malignant tumours of the duodenum. Rarely, patients present severe bowel obstruction, perforation or severe bleeding. The radical resection with complete removal of the tumour remains the main therapeutic approach. We performed a local resection in patients with suspected GIST admitted for emergency treatment for GI bleeding...

INTRODUCTION: Brush cytology is a rapid, cost-effective, and reliable tool to diagnose gastrointestinal tract (GIT) lesions in low-resource settings. Most of the studies on GIT brushings have focused on upper GI lesions. We have studied the diagnostic accuracy of brush cytology in the entire length of GIT and correlated the cytological diagnosis with histopathology. The aim of this study is to study diagnostic utility of brush cytology of GIT lesions in the context of correlation with biopsy and study the factors responsible for cytohistological discordance...

Patients who underwent resection of maxilla due to benign or malignant tumor, or accident will have defect in palatal area. They get retention, support and stability from remaining tissues which are hardly optimal. The advantage of swing-lock attachment design is having multiple contacts on labial and lingual side of the abutment teeth by retentive strut and palatal bracing component. Because the force is distributed equally to abutment teeth, abutment teeth of poor prognosis can be benefited from it. It is also more advantageous to cover soft tissue defects which are hard to reach with conventional prosthesis...

Treatment for type 1 Gaucher disease (GD1) decreases morbidity from hematological cytopenias, hepatosplenomegaly and bone complications. Consequently, untreated symptomatic patients for study of late outcomes are hard to find. We identified 184 untreated GD1 patients (67.4% Ashkenazi; splenectomy 51.1%) who died between 1950 and 2010. Here, we report confirmed causes of death for these patients compared with the overall US population. Median age of death 66years (2-97years); causes of death (COD) with a high proportional mortality rate (PMR) included malignancies (PMR 1...

Pancreatic ductal adenocarcinoma (PDAC) constitutes one of the most aggressive malignancies with a 5-year survival rate of <7%. Due to growing incidence, late diagnosis and insufficient treatment options, PDAC is predicted to soon become one of the leading causes of cancer-related death. Although intensified cytostatic combinations, particularly gemcitabine plus nab-paclitaxel and the folinic acid, fluorouracil, irinotecan, oxaliplatin (FOLFIRINOX) protocol, provide some improvement in efficacy and survival compared with gemcitabine alone, a breakthrough in the treatment of metastatic pancreatic cancer remains out of sight...

BACKGROUND: Clinicians are advised to refer patients with lower gastrointestinal (GI) alarm features for urgent colonoscopy to exclude colorectal cancer (CRC). However, the utility of alarm features is debated. AIM: To assess whether performance of alarm features is improved by using a symptom frequency threshold to trigger referral, or by combining them into composite variables, including minimum age thresholds, as recommended by the National Institute for Health and Care Excellence (NICE)...

Endoscopic submucosal dissection (ESD) is an innovative advance in the treatment of early gastrointestinal (GI) cancer without lymph node metastases and precancerous lesions as it is an effective and safe therapeutic method. ESD has also been a promising therapeutic option for removal of submucosal tumors (SMTs) for improving the completeness of resection of a large lesion. Endoscopic ultrasonography (EUS) can be used to detect the depth of invasion during the preoperative evaluation because of its close proximity to the lesion...

Pnina Brodt
Liver metastases remain a major barrier to successful management of malignant disease, particularly for cancers of the gastrointestinal tract but also for other malignancies, such as breast carcinoma and melanoma. The ability of metastatic cells to survive and proliferate in the liver is determined by the outcome of complex, reciprocal interactions between tumor cells and different local resident subpopulations, including the sinusoidal endothelium, stellate, Kupffer, and inflammatory cells that are mediated through cell-cell and cell-extracellular matrix adhesion and the release of soluble factors...

OBJECTIVE: Endoscopic mucosal resection (EMR) is established for the management of benign and early malignant upper GI disease. The aim of this observational study was to establish the effect of endoscopist procedural volume on mortality. DESIGN: Patients undergoing upper GI EMR between 1997 and 2012 were identified from the Hospital Episode Statistics database. The primary outcome was 30-day mortality and secondary outcomes were 90-day mortality, requirement for emergency intervention and elective cancer re-intervention...

Cancer cells are characterized by altered metabolic processes. Recent evidence of metabolic alterations has indicated that the fatty acid oxidation (FAO) pathway is used as a carbon source for anabolic processes in some tumors, thus making this pathway a potential target for therapy. The carnitine palmitoyltransferase (CPT; EC 2.3.1.21) enzyme transfers long-chain fatty acids from the cytosol to the mitochondrial matrix for β-oxidation. Because carnitine palmitoyl transferase 1a (CPT1a) is the rate-limiting enzyme for FAO, the authors evaluated the effects of CPT1A knock-down in BRAF V600E melanoma cell lines...
