#1
REVIEW
Rupert Langer, Karen Becker
Neoadjuvant therapy has been successfully introduced in the treatment of locally advanced gastrointestinal malignancies, particularly esophageal, gastric, and rectal cancers. The effects of preoperative chemo- or radiochemotherapy can be determined by histopathological investigation of the resection specimen following this treatment. Frequent histological findings after neoadjuvant therapy include various amounts of residual tumor, inflammation, resorptive changes with infiltrates of foamy histiocytes, foreign body reactions, and scarry fibrosis...

A sufficient quantity and quality of colostrum must be fed quickly to the newborn calf while minimizing bacterial contamination. Adenosine triphosphate bioluminescence swabs offer a potential rapid on-farm alternative to assess bacterial contamination of colostrum. The objective of this study was to validate the Hygiena (Camarillo, CA) AquaSnap Total (AS), SuperSnap (SS), PRO-Clean (PC), and MicroSnap Coliform (MS) swabs as well as visual hygiene assessment for detection of elevated bacterial counts in or on colostrum-feeding equipment...

BACKGROUND: Although endoscopic resection (ER) may be sufficient treatment for early-stage esophageal cancer, additional treatment is recommended when there is a high risk of cancer recurrence. It is unclear whether delaying esophagectomy by performing and assessing the success of ER affects outcomes as compared with immediate esophagectomy without ER. Additionally, long-term survival after sequential ER and esophagectomy required further investigation. METHODS: Between 2011 and 2015, 48 patients with stage T1 esophageal cancer underwent esophagectomy after ER with curative intent at our institution...

PURPOSE: Randomized trials examining neoadjuvant chemoradiotherapy followed by surgical resection (nCRT-S) and definitive CRT (dCRT) for esophageal cancer (EC) patients are hampered by use of nonstandard treatment paradigms. Outcomes of nCRT-S versus dCRT in a more common patient population are lacking. We investigated local control and survival, evaluated clinical factors associated with endpoints, and assessed patterns of failure between these cohorts. METHODS: We retrospectively analyzed 130 patients with locally advanced EC receiving either dCRT or nCRT-S at our institution from 2000-2012...

Patients with liver cirrhosis and variceal hemorrhage are at increased risk of rebleeding. We performed a meta-analysis toassess the clinical efficacy of combination therapy (pharmacotherapy and endoscopic variceal ligation (EVL)) compared with pharmacotherapy, EVL, or transjugular intrahepatic portosystemic shunt (TIPS) alone in the prevention of rebleeding and mortality. A literature search of MEDLINE, EMBASE, and the Cochrane Controlled Trials Register, up until November 2016, identified relevant randomized controlled trials...

Remarkably, majority of the cancer deaths are due to metastasis, not because of primary tumors. Metastasis is one of the important hallmarks of cancer. During metastasis invasion of primary tumor cells from the site of origin to a new organ occurs. Metastasis associated proteins (MTAs) are a small family of transcriptional coregulators that are closely associated with tumor metastasis. These proteins are integral components of nuclear remodeling and deacetylation complex (NuRD). By virtue of being integral components of NuRD, these proteins regulate the gene expression by altering the epigenetic changes such as acetylation and methylation on the target gene chromatin...

Previous study has demonstrated that high mobility group nucleosome-binding domain 5 (HMGN5) is involved in tumorigenesis and the development of multidrug resistance in several human cancers. However, the role of HMGN5 in esophageal squamous cell carcinoma (ESCC) remains unclear. Here, we showed that HMGN5 was significantly upregulated in ESCC cells. Knockdown of HMGN5 significantly inhibited cell growth and induced cell apoptosis of ESCC cells. Moreover, knockdown of HMGN5 increased the sensitivity of ESCC cells towards cisplatin...

Several plant pathogen Fusarium species produce fumonisins (FUMs); which can end up in food and feed and; when ingested; can exhibit harmful effects on humans and livestock. Mycotoxin intoxication by fumonisin B₁ (FB₁) and fumonisin B₂ (FB₂) can cause porcine pulmonary edema; leukoencephalomalacia in equines; esophageal cancer and birth defects by natural contamination. Herein; the occurrence of FB₁ and FB₂ in feedstuff (compound feed and feed ingredients) was investigated between 2011 and 2016 in South Korea...

There is increasing evidence that cytoskeleton remodeling is involved in cancer progression. Wiskott-Aldrich syndrome Protein (WASP) family represents a key regulator of actin cytoskeleton remodeling. However, the underlying mechanism of WASP family in cancer progression remains elusive. Here, we studied the role of WASP and SCAR Homolog (WASH), a recently identified WASP family member, in human esophageal squamous cell carcinoma (ESCC). Using three human ESCC cell lines, we found that WASH expression was significantly elevated in cancer stem-like cells enriched by sphere formation assay...

Gastric and esophageal cancers frequently show genomic instability and aneuploidy. Chromosomal copy number instability (CIN) is a form of genomic instability that exerts pleiotropic effects on cellular biology and is a source of genetic heterogeneity in a population of cells. CIN results in cell-to-cell variation in chromosome copy number which can be detected and quantified by fluorescence in situ hybridization (FISH). CIN is a biomarker associated with differential response to a number of chemotherapy compounds...

Chronic hyperglycemia is a well-known cause of gastrointestinal motility disorders extending from the esophagus to the anorectum. Even though little attention has been paid to esophageal disorders in the context of DM, its prevalence is higher compared to gastroparesis. Heartburn, as a typical symptom of gastroesophageal reflux disease (GERD), is the most prevalent symptom and has been found in 25 to 41% of patients with DM. Furthermore, DM has recently been established as possible independent factor for the development of Barrett's esophagus...

Sarcina ventriculi is a Gram-positive, obligate anaerobic coccus, with a characteristic morphology. Only 22 cases of human infections by this microorganism, including 7 in children, have been reported in literature so far. Affected subjects usually present with abdominal pain, nausea, vomiting, and delayed gastric emptying. However, life-threatening complications, like emphysematous gastritis and gastric perforation have also been described. Gastroparesis and gastric outlet obstruction have been considered as a potential etiologic factor...

The poor clinical outcome and prognosis of esophageal squamous cell carcinoma (ESCC) is mainly attributed to its highly invasive and metastatic nature, making it urgent to further elicit the molecular mechanisms of the metastasis of ESCC. The function of each polycomb chromobox (CBX) protein in cancer is cell-type-dependent. Although CBX8 has been reported to promote the esophageal squamous cell carcinoma (ESCC) tumorigenesis, its role in ESCC metastasis has not been explored yet. In this study, we report that the inhibition of cell migration, invasion, and metastasis in ESCC requires CBX8-mediated repression of Snail, a key transcription factor that induces epithelial-to-mesenchymal transition (EMT), and that CBX8 inversely correlated with Snail in the ESCC tissues...
