Abstract
To the best of our knowledge, this is the first report of ectopic gastric mucosa appearing between muscularis mucosae and submucosa, at esophagogastric junction. Currently there are two theories explaining the mechanism. The most widely accepted one is that Ectopic gastric mucosa is an embryological remnant, and an alternative theory is abnormal proliferation under inflammation1.Although we don’t have many evidences to clarify this case into specific mechanism mentioned above, Nomura et reported two cases of Adenocarcinoma of the cervical esophagus arising from ectopic gastric…

Abstract
Colon interposition is a surgical procedure used for maintenance of luminal conduit after esophagectomy. Although epithelial neoplasia, such as adenoma and adenocarcinoma, may develop in the interposed colon, there are only few case reports on the condition. Due to the rarity of this condition, there is no definite consensus on recommending screening endoscopy for the early detection of neoplasia in the interposed colons. Here, we report a case of intramucosal adenocarcinoma in an interposed colon. Initial endoscopic resection for …

Abstract
BACKGROUND: Solitary fibrous tumor (SFT) is a rare mesenchymal neoplasm affecting soft tissues with a not well defined biological behavior. SFT occurs mostly in the pleura and the thorax, while extra-thoracic localization is uncommon and abdominal localization is very rare. Histologically, SFT is a well defined mass with splindle-cell proliferation in collagenous matrix with staghorn vascular network and CD34 reactive.
CASE REPORT: A 64 years-old man with a history of recurrent gastric cancer previously treated with total gastrectomy, w…

ConclusionMANEC is very rare, aggressive, rapidly spreading, usually with poor prognosis disease.

This study aimed to investigate expressions of lncRNA FOXCUT in gastric adenocarcinoma patients and its effects on the cell biological function.
PATIENTS AND METHODS: Expressions and survival of lncRNA FOXCUT in gastric adenocarcinoma patients (GA) in the Cancer Genome Atlas (TCGA) database were collected. Fifty patients with GA treated in our hospital (patient group) and another 50 contemporaneous normal people (normal group) were collected. Expressions of lncRNA FOXCUT in GES1, SNU-5, HGC-27, SGC-7901, and AGS cells were detected. Also, si-lncRNA FOXCUT and si-NC sequences were transfected to SGC-7901. Si-RNA and si-…

Chronic inflammation takes part in the pathogenesis of some malignancies of the gastrointestinal tract including colorectal (CRC), gastric and esophageal cancers. The use of ω3 polyunsaturated fatty acids (ω3-PUFAs) supplements for chemoprevention or adjuvant therapy of gastrointestinal cancers is being investigated in the recent years. Most evidences have been reported in CRC, although their protective role has also been reported for Helicobacter pylori-induced gastric cancer or Barrett’s esophagus-derived adenocarcinoma. Studies based on ω3-PUFAs supplementation in animal models of familial adenom…

ConclusionsPET/CT, as a non-invasive method, can be preferred as the first choice in the detection of primary tumor in patients with BMUO.ResumenObjetivoEste trabajo analiza el papel de la PET/TC con 18F-FDG en la detección del tumor primario en pacientes con metástasis óseas de origen desconocido (MOOD).Material y MétodosEste estudio retrospectivo consideró al análisis histopatológico o el seguimiento clínico como datos de referencia en el diagnóstico de tumores primarios y estos resultados fueron comparados con los resultados de la PET/TC.ResultadosSe incluye…

Abstract
The cytology of peritoneal washing fluids for gastric cancer is the most basic method for judging peritoneal micrometastasis. However, the clinical value of this method is not clear at present. A retrospective analysis was performed on 277 patients with pathologically proven and surgically treated gastric cancer. The peritoneal washing fluids were collected after opening the abdomen and before the operation, and were sent to the cytology laboratory for screening of occult cancer cells in the collected washing fluids. The number of cases diagnosed as cancer cells, reactive mesothelial cells, serosal balls,…

Abstract
Gastric cancer (GC) remains to be a familiar malignant tumor with poor prognosis and daunting impacts on global health. We planned to grab the latent impacts of microRNA-183 in regulating cell autophagy, thus to clarify its possible regulatory principle in GC. The miR-183 level in GC tissues and cell lines was investigated. The impacts of miR-183 dysregulation on cell biological performances including viability, apoptosis and autophagy of GC cell lines including SGC-7901 were detected. Also, cells were disposed with 3-methyladenine (3-MA, an autophagy inhi…

Conclusion: PG is more preferable to TG for treatment of upper-third gastric cancer.
